Coming down: CLPS: Firefly’s Blue Ghost 1
Firefly Aerospace says that its Blue Ghost 1 lunar lander mission has ended as expected, completing all its objectives. Look at this Space News article for more details.
CLPS is making the Moon a busy place. While the IM-2 CLPS mission is targeting a March 6th landing, Firefly’s Blue Ghost 1 has already successfully landed – this one in Mare Crisium. Here’s what they brought with them:
Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER)
LISTER is one of two payloads provided by Honeybee Robotics (Blue Origin). LISTER will measure the heat flow from the interior of the Moon. To achieve that, that probe will penetrate more than 2 m into the ground, using a pneumatic drill, and then measure the thermal gradient and the thermal conductivity for the depth interval of the regolith penetrated, using a custom-built heat flow needle.
This is being done to “provide key constraints to the Moon’s thermal evolution and the history of the crust-mantle differentiation”, as Honeybee states on their page.
Whether the instrument was named for the third-class technician of the mining ship Red Dwarf, Dave Lister, remains unknown.
Lunar PlanetVac (LPV)
The other Honeybee Robotics (Blue Origin) payload is their planetary sample collection device PlanetVac. It will collect lunar regolith by firing a blast of gas into the lunar surface to disturb the regolith and loft it into a collection chamber. There it will be visually inspected using a camera and sieved using further gas jets. This will be done within the sorting station to test regolith dust adhesion and efficiency of gas jets as a cleaning agent. And it will demonstrate this fast and low cost, low mass alternative for sample collection.
The development of PlanetVac was supported by the Planetary Society and its members.
Next Generation Lunar Retroreflector (NGLR)
NGLR (University of Maryland) will support the determination of the distance between Earth and the Moon by reflecting very short laser pulses from Earth-based Lunar Laser Ranging Observatories (LLROs) and measuring the laser pulse transit time to the Moon and back, supporting sub-millimeter range measurements. More detail at NASA.
Radiation Tolerant Computer (RadPC)
This totally RadPC (Montana State University) will demonstrate a computer that can recover from faults caused by ionizing radiation. While RadPC prototypes have already been tested aboard the ISS and Earth-orbiting satellites, this will prove the biggest trial yet by demonstrating the computer’s ability to withstand space radiation passing through the Earth’s radiation belts, while in transit to the Moon, and on the lunar surface.
Electrodynamic Dust Shield (EDS)
The moon is a very dusty place, and it is a good idea to have tech to deal with this. For example, by using electric fields to move dust from surfaces and to prevent dust from accumulating. The EDS (NASA Kennedy Space Center) can lift, transport, and remove particles from surfaces with no moving parts, and will demonstrate the ability for the first time on the lunar surface, showing the feasibility of self-cleaning glass and thermal radiator surfaces. The EDS will be released from a fifth leg of the lander and positioned directly onto the lunar surface to maximize dust contact.
Lunar Environment heliospheric X-ray Imager (LEXI)
LEXI (Boston University; NASA Goddard Space Flight Center; Johns Hopkins University) will capture a series of X-ray images to study the interaction of solar wind and the Earth’s magnetic field that drives geomagnetic disturbances and storms. This instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact Earth.
Lunar Magnetotelluric Sounder (LMS)
LMS (Southwest Research Institute) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed.
Lunar GNSS Receiver Experiment (LuGRE)
LuGRE (Italian Space Agency (ASI); NASA Goddard Space Flight Center) will receive and track signals from the GPS and Galileo navigation satellite constellations during the Earth-to-Moon transit and throughout a full lunar day on the Moon’s surface. This demonstration will help characterize and extend Global Navigation Satellite System (GNSS)-based navigation and timing to lunar orbit and the Moon’s surface, providing lunar spacecraft with accurate position, velocity, and time estimations autonomously, on board, and in real time.
Stereo CAmera for Lunar Plume-Surface Studies (SCALPSS)
SCALPSS (NASA Langley Research Center) will use stereo imaging photogrammetry to capture the impact of rocket plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion – an important task as bigger, heavier payloads are delivered to the Moon near each other.

Coming Down: CLPS Flight | Intuitive Machines IM-2
On Feb 27th, 2025, the latest mission that is part of NASA’s Commercial Lunar Payload Services (CLPS) initiative has launched from NASA’s Kennedy Space Center in Florida. For this mission, going up is important, but coming down even more so. Because Intuitive Machines’ IM-2 is going to land on the moon – hopefully on March 6th, 2025.
Let’s have a look at what IM-2 brings to the moon
Update:
Intuitive Machines has stated that “IM-2 mission lunar lander, Athena, landed 250 meters from its intended landing site” and has tipped over. Lying on its side, the solar panels could not deploy and the batteries quickly depleted. The mission was declared concluded.
Athena
Athena is sort of the mothership that will bring many exciting payloads safely to the lunar surface. It is IM’s second Nova-C class lander. The machine provides the ride to the lunar surface and also communication services for the different missions. It stands at 4.73 m (15.3 ft) tall, which means it is roughly the height of a shorter adult giraffe.
Now let’s see what it carries to the moon. There are NASA payloads and commercial payloads.
NASA Payloads
The first is NASA’s POLAR RESOURCES ICE MINING EXPERIMENT 1 (PRIME-1) drill suite, which consists of – you guessed it – a drill and a mass spectrometer.
TRIDENT (The Regolith Ice Drill for Exploring New Terrain) will attempt to drill up to 1 meter deep and extract lunar soil – called regolith – and deposit it on the surface for analysis. It will also measure soil temperature at depth, which will help to validate existing lunar thermal models.
The drill suite’s Mass Spectrometer Observing Lunar Operations (MSolo) will identify light volatiles to either measure the lunar exosphere or the spacecraft outgassing and contamination. That can help to determine the composition and concentration of potentially accessible resources.
So the suite is a demonstrator for tech that can help search for and identify interesting resources on the moon towards mining them.
Commercial Payloads
NOKIA LUNAR SURFACE COMMUNICATIONS SYSTEM
We should start by mentioning Nokia’s cellular network because it will be providing the underlying connectivity between the Nova-C lander, two mission vehicles and the sensors they carry.
It is also a Nokia Bell Labs demonstrator, that wants to show that space-hardened cellular technologies based on some of the same commercial-off-the-shelf components used in 4G/LTE networks across the globe can work for such a mission. It intends to offer dependable, high-capacity and efficient connectivity and communication for tasks such as voice, video, data communication, telemetry and biometric data for both crewed and uncrewed lunar and planetary missions.
YAOKI ROVER
Dymon Co. Ltd. Yaoki Rover is a small, lightweight rover with a special way to go around: It is designed to be versatile and resilient, enabling it to be dropped in any orientation without a mechanism. The best way to understand how is to have a look at the video:
As for the rover: it is essentially a self-driving camera that will examine and demonstrate mobility and adaptability on the lunar surface close to the lander and hopefully take some cool images.
MAPP
Lunar Outpost’s MAPP (Mobile Autonomous Prospecting Platform) is an autonomous rover with a navigation system that can operate without GPS, using visual cues and sensors to navigate and avoid hazards. It is furthermore built in a way that should give access to previously unreachable regions.
MICRO NOVA HOPPER
The little craft called *Grace* is not called HOPPER because it hops. But that is precisely what it will do. Following the advice of why drive if you can fly, it will – if all goes well – perform several hops of 20–100 m in altitude. The penultimate hop is expected to be into a small permanently shadowed crater approximately one quarter of a mile from the landing site. This would be the first time that a permanently shadowed crater, is being explored.
At about 98 cm in height and 39 kg weight, it will carry enough fuel for a range of up to 25 km of autonomously going up, going sideways, and going down.
The IM-2 Micro Nova Hopper is named for Grace Hopper, the pioneer in mathematics and programming who worked on some of the earliest computers, and developed the first compiler and COBOL, a language still used today.
The Hopper will also carry two more instruments to gather relevant data:
LRAD – the Lunar Radiometer – built by the German Aerospace Center (DLR) and FU Berlin will study surface temperatures at the Moon’s South Pole, particularly in permanently shadowed regions where water ice may be stable.
PULI LUNAR WATER SNOOPER (PLWS) by Puli Space Technologies Ltd. of Hungary is a tiny spectrometer weighing just 400 grams. It will collect water ice indicator data from the Moon’s South Pole region, conducting the first-ever direct surface measurements from a permanently shadowed crater, supporting critical in-situ resource utilization (ISRU) efforts for future lunar exploration.
Landing Site and Duration
Athena is targeting the “Mons Mouton” region of the Moon, approximately only 100 miles from the Moon’s South Pole.
Mons Mouton is named after the mathematician Melba Mouton, one of the first “human computers” who played a key role in the early field of spacecraft trajectory and geodynamics.
The missions will have only about 10 days to complete their objectives before the sun sets on the lunar South Pole, rendering Athena inoperable as extreme temperatures take hold.
Rewatch the Launch
Going Up: SPHEREx and PUNCH
Going Up: sharing a ride to look at our sun and at distant galaxies
On March 6th, 2025 – if all goes as planned – two missions will share a ride on a Falcon 9 Block 5. They will share similar orbits but with very different intentions. They will both find their homes on a sun-synchronous low earth orbit. That means they will both circle our Earth along its day-night (or terminator) line. One, because that way it can constantly observe the sun. The other to constantly look away from the sun while remaining close to home. The one looking at the sun is called PUNCH, the one looking away SPHEREx.
SPHEREx
Scientists launching things into love their acronyms. So, of course, they would call their telescope staring into deep space to look for traces of water, carbon dioxide, carbon monoxide, and other key ingredients for life frozen on the surface of interstellar dust grains in the clouds of gas and dust where planets and stars eventually form SPHEREx. That is meant as a short description of the mission, as it is derived from it being a Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. So it could also have been called SPUERIEx – but that would have been spurious and made it sound vaguely Swiss.
To catch these reservoirs of ice, bound to small dust grains, in interstellar space, it will look outward from low-Earth orbit, circling the planet at an altitude of 700km along its day-night (or terminator) line. These reservoirs are where most of the water in our universe forms and resides. Additionally, the water in Earth’s oceans as well as those of other planets and moons in our galaxy likely originated in such locations.
During the 25 months of its planned mission, it will survey the entire sky every six months, collecting data on more than 450 million galaxies along with more than 100 million stars in the Milky Way. That way, it will create a map of the entire sky in 102 different color bands, far exceeding the color resolution of previous all-sky maps. It also will identify targets for more detailed study by future missions, such as NASA’s James Webb Space Telescope and Wide Field Infrared Survey Telescope.
SPHEREX is a Caltech and JPL mission, and Dr. Jamie Bock is the principal investigator.
The data they collect will be publicly available. So if you want to read more about this mission, see more pretty pictures and maybe take a look at the data, JPLs page and the SPHEREx mission website at Caltech should have everything you desire. And there is of course a Wikipedia page for the mission as well.
PUNCH
And now the weather – space weather. The Polarimeter to Unify the Corona and Heliosphere – PUNCH – mission is a small constellation of four suitcase-sized satellites that will also be hoisted to a Sun-synchronous, low Earth orbit by said Falcon 9. There they will fly at 570 km altitude along the day-night (terminator) line, giving them a continuous view of the sun.
The four spacecraft are synchronized to serve as a single “virtual instrument”. One will look at the sun, while the others will look to the side of the sun. Every four minutes, each will collect three raw images through three different polarizing filters, plus a clear (unpolarized) image every eight minutes, to help calibrate the polarized images. This will create a composite movie of the interactions between the sun’s corona and the interstellar medium, look at the dynamics of the heliosphere that creates, and will also be able to routinely track coronal mass ejections.
All this will help us better understand and predict solar storms – which is important for protecting our astronauts, our satellites, and power grids.
The data will be downlinked multiple times a day via ground-based antennas managed by the Swedish Space Corporation (SSC), who will send the data to the mission operations center at SwRI in Boulder, Colorado sharing it with the science operations center at SwRI and with the world. Because the data will be available to the public at the same time it is available to the science team. All PUNCH data will be published through the Solar Data Analysis Center at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, ensuring open access to the scientific community and public.
Craig Deforest is the PUNCH Principal Investigator, at SwRI (Southwest Research Institute). The mission blog is here and of course, there is a Wikipedia page
PUNCH is up and mission controllers for PUNCH (Polarimeter to Unify the Corona and Heliosphere) have received full acquisition of signal from the four small satellites, indicating that they are functioning normally and at full power.
SPHEREx & PUNCH: Studying the Universe and Sun
A new ERA in space – a different kind of perseverance
A new ERA in space A different kind of perseverance
It is 11 meters long and has an even longer history: ERA (European Robotic Arm), developed and built by ESA, launched to the ISS with the Russian multipurpose laboratory module NAUKA. Its journey from idea to space underscores one more time: space is hard and it can take a long time to get there. Let’s take a look at this arm’s journey into space.
HERA for HERMES
The robotic arm was first conceived of as the Hermes Robot Arm (HERA), a “robot that will support the Hermes Spaceplane in its primary mission: the servicing of the Columbus Free Flyer”. As such it was presented in the 1992 IEEE International Conference on Robotics and Automation. The paper is available on the IEEE Explore site.
Let’s unpack this apparently simple sentence for fun. So HERMES was a proposed ESA space plane that was supposed to launch on Ariane 5 and carry crew to LEO. It was in essence a small Space Shuttle, complete with a cargo bay and the robotic arm to bring payloads from the cargo bay of the space plane onto a small space station. Planning started in the 80s, the first launch was planned for 1998, which then slipped to the early 2000s.
It’s initial destination was the Columbus Free Flyer – an ESA program to develop a space station. That was cancelled in 1991 while still in the planning stages. Aspects of the program were later realised in the Columbus science laboratory attached to the International Space Station (ISS).
So with no destination and – after the end of the cold war – with access to space for crewed missions through both NASA and the Russian space program, HERMES was cancelled in 1992. But the robot arm design did not go away.
#MIR2
The next proposed use was for MIR-2, a Soviet space station project initiated in 1976. This project went through different iterations, some smaller, some bigger. The one thing they had in common was that they were built around a core module called DOS-8, that would provide housing for the assembly crew. At one point the space station would have included up to four 90-tonne modules attached to the DOS-8 module. The huge modules were to be launched on Energia. That was a heavy lift rocket designed to bring payloads of up to 96 t to LEO or lift Buran, the Soviet space shuttle, into orbit.
Where the Soviets were planning MIR-2, the Americans were looking to build their own large space station called Freedom. But then, the Iron Curtain came down.
ISS – first attempt
in 1999 ESA published a short film outlining role ERA would play on the ISS.
Now plans were made to merge the two large scale space station projects into what would ultimately become the ISS. Those plans came to fruition fairly quickly. In 1993 Zarya was launched as the first module of the ISS, followed by the US built Unity connecting module and then – in 2000 – the russian modul Zvesda, otherwise known as DOS-8.
The European Robotic Arm (ERA), as it was by now called, was going to be placed on the Russian Science Power Platform, also part of the MIR-2 design. But at some point, as Philippe Schoonejans put it an episode of the ESA Explore Podcast, “that got canceled (…). And I think the Russians had then decided that it was OK for them to use the power coming from the very, very large American solar arrays on the American system.”
Canceled? Again? But wait: you get the power from another place, but it’s called Science Power Platform, so what about science (Nauka in Russian)?
Nauka
Fourth time lucky? Planning for more Russian science modules to be attached to Zarya and Zvesda went back to the 90s. But a lack of funds caused many delays. Finally, in 2004, the decision was made to use the Zarya replacement module to build Nauka. The module had already been about 70% complete since 1998, and had not been needed because of the successful 1998 launch of Zarya. In 2005, it was agreed to launch ERA together with Nauka.
There were delays, of course, and technical difficulties. But now, not even 30 years after it was described in a paper, it has launched to the ISS atop a Proton-M carrier rocket.
ESA’S 2021 piece on the launch of ERA
Another arm
The International Space Station of course already features two robotic arms: Canadarm2 and the Japanese Experiment Module Remote Manipulator System. Both play a crucial role in berthing visiting vehicles and grappling external payloads on the US and Japanese modules. So why send another one? Just because it’s been on the books since 1992? Of course not. The Canadian and Japanese arms cannot reach the Russian segment of the International Space Station. The different types of base points and payload mounting units do not allow them to operate in other parts of the Station.
Now that it has launched, things are far from done. If you want to listen to somebody go into more detail of how the thing is going to play out until it is finally fully installed and tested and then carry something for the first time maybe in March 2022, I recommend this ESA Explores Podcast episode with Philippe Schoonejans (ESA), ERA project Manager.
The ISS is very much about learning how to space. So ERA is not only a very serviceable tool, but it can also teach us lessons human-robotic interaction in space that will be very useful when we go on to the Moon and beyond.
ERA was largely funded by the Dutch government with Airbus Defense and Space Netherlands as its prime contractors. So on twitter you can find a thread by @DutchSatellites that shows some more early conceptual drawings from ESA and Fokker. It’s fun, have a look.
Dinner with a view
Dinner With A View ESA Astronaut Thomas Pesquet: on his second mission to the ISS, he again brings dinner for the stars

A Gastronautic Mission
No matter if you’re living with people, working with them or meeting them for the first time – sharing a meal is always the Great Facilitator. And it’s nice, especially if the food is good. But if you are stuck in a tin can for months on end, food becomes important, as the US Navy knows: Because nuclear subs stay submerged for as long as 90 days straight, serving better food is a way to make up for what is considered to be one of the toughest assignments in the military.
“When we’re out to sea, the highlight of the day is food. There is not much else to look forward to,” says senior mess specialist Salvador Rico, a petty officer 1st class and an 11-year veteran of the nation’s nuclear submarine fleet. (LA Times)
The same is true if said tin-can is in LEO. The view may be more spectacular by a mile up there, the days packed with science and maintenance, but food is important for the joy it brings and the joy of sharing. Today “crew members can choose from about 200 different items for their standard menu that can be augmented with some personal choices to include commercial off-the-shelf items. ” The U.S. and Russian crew members bring food and like to share it. And “Astronauts from the other ISS partner agencies such as the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), and the Canadian Space Agency (CSA) often bring their own specialties that are shared among all the crew members.” (NASA – Space Station 20th: Food on ISS)
European Tradition
ESA regularly sends members of different nationality up to the ISS and has a tradition to tap culinary luminaries to create menus for their astronauts. They are meant as a greeting from their home country and meant to be shared on the ISS on a special occasion. Since Luca Parmitano’s spaceflight in 2013, each ESA astronaut has worked with a great cook from their own country to develop meals that remind them of their childhood or their favourite dish on earth. On Thomas Pesquet’s first flight, for example, he brought a special dinner with French flavors for New Years Eve 2016 created by star chef Thierry Marx.
ESA astronaut Thomas Pesquet gives a tour of the International Space Station’s kitchen and the special food he will share with his crewmates in space (ESA, 2016).
Not your usual take away.
Did I say “created”? The word should actually be “developed”. The ISS is a special place, and has some very specific requirements regarding food. It should, for example, not create crumbs – because you don’t want them floating around and clogging up air ducts. Food on the ISS is generally stored at ambient temperature and must remain stable at those conditions for quite a while. So no refrigerator (and the big one outside in the shade is hard to get to and way too cold). So foods are often freeze-dried or thermostabilized – i.e. heated foods to destroy pathogens, microorganisms, and enzymes that may cause spoilage – to achieve the required shelf-life.
So your lovely dish has to undergo quite a bit before it is acceptable for space travel – and it still has to taste like something. Development of these dishes starts anywhere from a year and half to two years before a mission, ESA crew support Susanne Altenburger explains: “We start selecting meals and testing well in advance because, as well as being approved by the astronaut, meals must be sent to the lab for safety and nutritional testing, after being freeze-dried, thermostabilised or vacuum packed,” she adds. (ESA)
This time around, Thomas Pesquet got to chose from two different chefs, six dishes in total that he hopes to share with his crewmates: “But there’s basically two full meals that I’m looking forward to sharing with my crew mates and maybe trading against some other food, there’s a lot of trading of food that happens on the space station.” (quoted from newschainonline) One of the chefs we know from Pesquet’s first trip to the ISS: Thierry Marx.
Thierry Marx
Thierry Marx is quite the famous chef. He held Michelin stars for his cuisine in more than one location, and was awarded two stars at the Relais et Château Cordeillan-Bages in 1999. Currently he is at the helm of several restaurants and a pastry counter. Marx is specialised in molecular cuisine, which is already very heavily involved in the physics and chemistry of cooking. So when it comes to creating space food, he is probably a perfect fit.
The recipes for Pesquet’s Alpha mission he developed together with researcher in physico-chemistry Raphaël Haumont, co-director of the Centre Français d’Innovation Culinaire at the University of Paris-Saclay, which he had founded in 2012 together with Thierry Marx.
The resulting dishes were then prepared and canned by Jean Hénaff, France’s leading brand of pâtés and rillettes. And this is what they cooked up:
Gâteau de pommes de terre / oignons de Roscoff truffés
A deceptively simple potato cake with truffled Roscoff onions. Those are special onions originating from the French region Finisterre. The Roscoff onion is very popular because of its delicious taste, vitamin C content, mildness, pretty pink colour and shelf life.
Bœuf de sept heures / sauce aux cèpes
Seven hour beef is just that: beef tenderly cooked for seven hours for special tenderness with a mushroom sauce. It requires red wine to make, but alcohol is a no-go on the ISS, so there were some special challenges to be overcome in developing this dish, as Raphaël Haumont points out: “Making a traditional alcohol-free wine sauce is the result of a long process. Ethanol should be extracted using a rotary evaporator. Fine analyzes (NMR) are then carried out to verify the absence of alcohol.”
Amandine poires caramélisées
This caramelised pear with almond garnish is a perfect fit for the occasion. Says Thierry Marx: “We have turned to low-sugar recipes with the shortest possible list of ingredients. This represents a new challenge. To make the amandine without adding sucrose, for example, we had to work on the texture of pear pectin which will provide us with natural sweetness and gelation.”
Ready for Launch
To get the delicious compositions ready for launch and ultimately a lovely dinner with a view, Jean Hénaff meticulously assembled the food by hand and packaged it fit for space: “Our expertise consists in perfectly crimping the boxes for absolute sealing and filling just what is needed in order to preserve the nutritional and taste properties of the recipes so that the astronauts find the flavors of the food intact. Earth and the pleasure of taste. The other challenge is to guarantee flawless microbiological safety,” says Carole Machut, R&D Manager of the Jean Hénaff Group. That the company has been designing around 2000 dishes per year for the ISS since 2011 and subsequently enjoys a USDA approval, certainly helped.
And of course they also took care of the presentation of the dishes. “The visual aspect of the dishes can have a comforting side for the astronaut. On the organoleptic profile, we want the dishes’ taste in space to be as close as possible to that on earth,” Carol Machut added. (quoted from archyde.com)
Francois Adamski
The other chef tasked with creating the culinary high-flyers is Francois Adamski, a celebrated chef in his own right, with a Michelin star and a Bocuse d’or. In 2019 he was appointed Coporate Chef at Servair, big, among other things, in airline catering.
Here, Pesquet got to choose between 10 suggestions – and he selected:
- Crunchy and creamy small spelt, melting celery and Périgord truffle (Petit épeautre croquant et crémeux, céleri fondant et truffe du Périgord
- Beef bourguignon, smoked farm breast, mushrooms and small glazed onions (le Bœuf bourguignon, poitrine fermière fumée, champignons et petits oignons glacés)
- Classic Crepes flambéed with Grand Marnier and orange zest, Suzette style (les Crêpes flambées au Grand Marnier et zestes d’orange, façon Suzette)
Those posed their own type of problems. For packaging they chose pouches rather than cans, says Boris Eloy (Executive Vice President, Innovation, Servair): “The real challenge was to develop a “gourmet” product with the constraints of heat treatment but also reduced sodium and alcohol content, all with a “dense” texture suitable for consumption in zero gravity. Unlike traditional canning, the flexible pouch technique made it possible to combine the preservation of the original flavours with a very long shelf life.”
Thomas Pesquet was invited to do a comparative tasting between the dishes prepared fresh and those sterilised in pouches. “For me, it was essential to preserve the flavors of the dishes, whether they were fresh or in sterilized bags.” François Adamski, Servair’s Corporate Chef, said. “We work diligently to adjust the seasonings every time until we obtained a product that was very close in taste to its non-space version” (quoted from servair press release).
Matter of Taste
While you can theoretically endeavor to follow the special food and cook it fresh as Pesquet is sharing it with his crewmates on the ISS, it will never quite the same – because of gravity: On Earth, gravity causes body fluids to settle toward the feet, but in space, those fluids can float freely throughout the body. The retention of fluids in the head can have the same effect as congestion from a cold or virus. Congestion lessens the ability to smell and, therefore, taste food, which can lead to a preference for hot peppers and other spicy items, as this npr-article pointed out.
“Your head sort of inflates like someone is squeezing the bottom of a balloon,” says Chris Hadfield, who also adds that the effect disappears after a few days, and food tastes the same.
Mission specialist Clayton Anderson, who spent 152 days on the ISS as a flight engineer for Expedition 15 in 2007, says he only suffered from congestion the first few days there, although it returned intermittently. Nevertheless, he found some foods to be bland, whereas others that he had tasted and disliked preflight, such Tvorg (a tangy Russian cottage cheese dish with fruit and nuts) became space station faves.(quoted in Scientific American)
Then there is also the odours in the ISS, although opinions there also seem to vary: Scott Kelly stated once, that the ISS smelt like prison: “I was touring the Harris County Jail, and there’s this room that smells like space station—combination of antiseptic, garbage, and body odor. You know how on Earth, with gravity, stuff tends to rise or fall depending on its weight compared to air? On the ISS, that doesn’t happen, so smells can kind of linger.” (quoted in wire.com). Kjell Norwood Lindgren though was surprised about how fresh the ISS appeared to him thanks to impressive technology in the space station’s life support system. “The air in the space station actually smelled great,” he said in a video. “The filters in the life support system do a great job cleaning the air. There were no issues at all.”
And finally – a tiny little TEDx talk
If you want to know more about the challenge of preparing a special meal for the ISS, I have a talk for you: it is a TEDx talk by Thorsten Schmidt. He is the Danish chef who prepared the meals for Danish ESA astronaut Andreas Mogensen, and he will take you through his journey to that goal.
Become a Planetary Defender Today
On 10 September 2020 an asteroid missed our planet by 40 million kilometers, more than 100 times the distance between Earth and the Moon.
It was detected only very recently by amateur astronomer Leonardo Amaral of the Campo dos Amarais observatory in Brazil.
To quote Planetary Society’s Chief scientist Bruce Betts: “the fact that this relatively large near-Earth object, or NEO, wasn’t detected until now serves as a reminder that there’s much work to be done when it comes to defending our planet from dangerous asteroids”.
Leonardo Amaral’s important discovery was supported by the members of The Planetary Society, which awarded Amaral an $8,500 Shoemaker NEO grant to purchase a more stable telescope mount for better tracking and longer camera exposures.
You, too, can become a Planetary Defender by donating. Every dollar will power our crucial planetary defense initiatives.

Mars Missions 2020
Mars Missions 2020
This year will see four missions launching to Mars. The timing is of course dictated by the orbits of Mars and Earth in relation to another, which open a good launch window every two years. But the number also shows how space exploration has become a global affaire instead of one conducted only by a few nations.
(Titel image ESA/Roscosmos/CaSSIS, CC BY-SA 3.0 IGO )
ExoMars
This is part two of a mission that started in 2016. Part one brought the Trace Gas Orbiter (TGO) into Mars orbit and released the Schiaparelli EDM lander. The TGO has since produced some interesting science. The lander did not land successfully, proving that a) space is hard, and b) you test to learn from your failures.
Part two will now deliver the Rosalind Franklin rover, named after the X-Ray cristallographer so instrumental in the discovery of the structure of DNA. It will land using the Kazachok lander and descent stage.
One of the main instruments will be a drill to “retrieve samples from up to 2 m below the surface, delivering them to the onboard science laboratory for detailed analysis to sniff out signs of biological signatures.” (see this ESA-post for more details)
The entire mission is dedicated to help answer the question whether life has ever existed on Mars.
Launch
Launch window starts September 20th, 2022.
The launch will be from Baikonur, Kazakhstan on a Proton M Rocket.
Landing
The ExoMars Lander and Rover is expected to land 264 days after launch, so maybe on 10 June 2023.
Oxia Planum was chosen as the preferred landing site for the rover, with Aram Dorsum and Mawrth Vallis as backup options.
Space Agency
European Space Agency (ESA) and the Russian space agency Roscosmos
Mars 2020 / Perseverance
The mission will bring a rover to Mars now named Perseverance, that is based on the Curiosity rover but with all new instruments.
It will also have a drill. And it will also be about bio-signatures – to quote Wikipedia: “It will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials.”
Here is an overview of all instruments on board the rover.
It is also the first step for the proposed Mars sample return mission – which now looks like it could actually happen, as both ESA and NASA have been given budget to perform part of this complex mission.
There is also a NASA JPL fact sheet for the mission (PDF).

Launch
Launched July 30th from Cape Canaveral Air Force Station, Florida on an Atlas V.
Landing
The Mars2020 Rover has landed safely on 18 February 2021. Watch the amazing video from EDL cams showing the Perseverence POV.
It has landed in Jezro Crater. It currently is here.
Space Agency
Part of NASA’s Mars Exploration Program.
Hope Mars Mission
The Hope Mars Mission – aka the Emirates Mars Mission – is a probe (not a lander) that wants to provide a complete picture of the Martian atmosphere and its layers and so help answer key questions about the global Martian atmosphere and the loss of hydrogen and oxygen gases into space over the span of 1 Martian year.
As it is a cooperation between the Mohammed bin Rashid Space Centre, the University of Colorado and Arizona State University it is also a contribution towards a knowledge-based economy in the UAE.
More details are available on Wikipedia’s Hope Mars Mission page and on the Mohammed bin Rashid Space Center’s project page.
Launch coverage:
Launch
Launched July 20th, 2020 from Tanegashima LA-Y1 in Japan on a Mitsubishi H-IIA launch vehicle.
Orbital Insertion
The United Arab Emirates’ first Mars mission, Hope, successfully entered orbit around the planet Feb. 9.

Mars Global Remote Sensing Orbiter and Small Rover - Tianwen-1
The Chinese Mars Global Remote Sensing Orbiter and Small Rover is now officially named Tianwen-1, meaning ‘questions to heaven’. The name was revealed on China Space Day, marking the 50th anniversary of the launch of China’s first satellite, DFH-1, on April 24th.

The priorities of the mission include finding both current and previous life, and evaluating the planet’s surface and environment. Solo and joint explorations of the Mars orbiter and rover will produce maps of the Martian surface topography, soil characteristics, material composition, water ice, atmosphere, ionosphere field, and other scientific data will be collected.
CNSA initially focused on the Chryse Planitia and on the Elysium Mons regions of Mars in its search for possible landing sites for the lander and its associated rover. However, in September 2019, during a joint meeting in Geneva of the European Planetary Science Congress-Division for Planetary Sciences, Chinese presenters announced that two preliminary sites in the Utopia Planitia region of Mars have instead been chosen for the anticipated landing attempt, with each site having a landing ellipse of approximately 100 by 40 kilometers.
