  • China invites Brazil to participate in its lunar base project

    • There is no indication Brazil accepted the offer. The offer took place during a meeting between officials of the Brazil Space Agency and one of China’s pseudo-companies, China Great Wall Industry Corporation (which according to Jay “is the international launch service subsidiary” for China). Thus, this could be an effort by that pseudo-company to gain launch access to Brazil’s recently reactivated Alcântara spaceport.

Exploring the cratered southern highlands of Mars, part 2

1:44 pm

Overview map

Dune-bedrock contact in Rabe Crater
Click for original image.

Our travels in the cratered southern highlands of Mars continues. Today we visit 67-mile-wide Rabe Crater, as indicated on the overview map above. The picture to the right, cropped and reduced to post here, was taken on January 27, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Rabe Crater is significant for several reasons. First, it was one of the first places on Mars where sand dunes were identified, by one of the Viking orbiters in the late 1970s [pdf]. Second, the pits and sand in its interior, are unusual and puzzling. The inset on the overview map provides a closeup look at the crater. The yellow mound in the central south of the crater floor is all dunes, which are surrounded by the pit with steep cliffs more than a 1,000 feet high.

University of Arizona opens major facility for building and launching satellites

12:27 pm

anechoic chamber at UA's Applied Research Building
ARB’s anechoic chamber

Yesterday I attended the grand opening of the University of Arizona’s (UA) new Applied Research Building (ARB), designed to provide satellite builders as well as its students an almost completely comprehensive facility for the assembly, testing, and launching of satellites. From this event announcement:

To keep the university at the forefront of space science and exploration, ARB will serve as a world-class test and integration center for satellites, probes, and spacecraft, including:

  • A 40-foot tall high-bay payload assembly area used for constructing high-altitude stratospheric balloons and nanosatellites also known as “CubeSats.”
  • A thermal vacuum chamber that simulates environmental conditions in space to test balloon and satellite performance that is the largest of its kind at any university in the world.
  • A non-reflective, echo-free room called an anechoic chamber to test antennae for command, control, and data relay purposes.
  • A large lab for testing the performance of a range of objects, from airplane wings to sensors.

The anechoic chamber is pictured above. For scale, if a person was standing in the middle of the chamber their height would reach about six rows up. The carbon-infused styrofoam pyramids are designed to dampen reflections of radio signals in order to simulate the space environment while testing the antennas on a satellite. This is apparently is of the largest such chambers in the United States.

Webb snaps infrared picture of Uranus

10:11 am

Uranus as seen in the infrared by Webb
Click for original Webb false-color image.

In a follow-up to a recent Hubble Space Telescope optical image of Uranus, scientists have now used the Webb Space Telescope to take a comparable picture in the infrared of the gas giant.

Both pictures are to the right, with the Webb picture at the top including the scientists’ annotations.

On the right side of the planet there’s an area of brightening at the pole facing the Sun, known as a polar cap. This polar cap is unique to Uranus – it seems to appear when the pole enters direct sunlight in the summer and vanish in the fall; these Webb data will help scientists understand the currently mysterious mechanism. Webb revealed a surprising aspect of the polar cap: a subtle enhanced brightening at the center of the cap. The sensitivity and longer wavelengths of Webb’s NIRCam may be why we can see this enhanced Uranus polar feature when it has not been seen as clearly with other powerful telescopes like the Hubble Space Telescope and Keck Observatory.

At the edge of the polar cap lies a bright cloud as well as a few fainter extended features just beyond the cap’s edge, and a second very bright cloud is seen at the planet’s left limb. Such clouds are typical for Uranus in infrared wavelengths, and likely are connected to storm activity.

The Webb image also captures 11 of Uranus’s 13 rings, which appear much brighter in the infrared than in the optical.

Unlike all other planets in the solar system, Uranus’s rotation is tilted so much that it actually rolls as it orbits the Sun, a motion that is obvious by comparing these pictures with Hubble’s 2014 optical picture.

China tests vertical landing of small rocket from barge at sea

9:51 am

China's own version of SpaceX's Grasshopper

A commercial division of the Chinese Academy of Sciences (CAS) has successfully test flown its own a very small version of SpaceX’s Grasshopper, doing a vertical lift off from a barge at sea and then landing vertically on that barge.

The rocket prototype flew at an altitude of more than 1,000 meters, descended in a smooth hovering fashion and then decelerated thanks to the engine reverse thrust. The landing speed was reduced to less than two meters per second at the final stage before the rocket touched down steadily with a landing precision of under 10 meters.

The landing test took about 10 minutes, the CAS institute revealed.

The small scale of the rocket, as shown by the screen capture above, taken from the short video CAS produced of the flight, shows that CAS is a long way yet from using this technology in an orbital flight. Nonetheless, it demonstrates that at least two Chinese pseudo-companies are working hard to copy SpaceX’s reusable Falcon 9 first stage. With this test CAS has demonstrated it now has the software and fine engine control for vertical rocket landings. Based on the image of its proposed rockets at this tweet, this prototype will eventually lead to the development of larger orbital versions that look remarkably similar to what SpaceX produces.

Spaceplane startup flies small-scale prototype for the 1st time using new rocket engine

9:31 am

The startup Dawn Aerospace, based in New Zealand, has now successfully flown a small-scale prototype of its proposed spaceplane using for the first time the company’s Aurora rocket engine.

Mk-II Aurora, a scaled down version of the spaceplane Dawn is developing for commercial operations, took to the skies March 29, 30 and 31 from New Zealand’s Gentanner Aerodrome. The initial test campaign validated key flight systems and demonstrated the benefit of rapid reusability, Dawn CEO Stefan Powell told SpaceNews.

During the first flight, the Mk-II Aurora consumed more fuel than anticipated due to a leak in the propellant system. The next day, Dawn engineers removed the Mk-II Aurora engine, took out the oxidizer tank and found the leak.

These rocket-powered test flights are a follow-up of an earlier test program in 2021 using jet engines. You can get a sense of the scale of the prototype from a picture at this article.

The company plans to fly this prototype to as high as twelve miles later this year before moving on to a larger test version. Eventually it hopes to develop a two-stage orbital system. The details however remain vague. The 2021 release suggested it was building a two-stage-to orbit version that will take off from a runway and then launch small satellites into orbit. These new stories suggest it are presently targeting the suborbital unmanned research market, with the eventual ability to do frequent flights to 70 miles altitude. Launching orbital satellites is presently only a distant goal.

  • Tianzhou freighter will fly in formation with China’s Tiangong-3 space station

    • The plan is to periodically redock the freighter to the station “when inventories stored inside are needed.” Jay wonders whether this is a test of the similar formation flying that will be required when China’s space telescope arrives next year to orbit near the station for periodic maintenance and repair. I think he is correct.

Exploring the cratered southern highlands of Mars, part 1

Overview map of southern cratered highlands of Mars

Glacial filled crater
Click for original image.

Today and for the next three days the cool images that I will post from Mars will explore a region that I have not covered very much in depth, the cratered southern highlands between the giant basins Argyre and Hellas. The map above is an overview of this 7,000-mile-long region, all of which is inside the 30 to 60 degree south latitude band where scientists have found much evidence of buried glaciers. In this region the bulk of that evidence is most obvious inside craters.

The picture to the right, cropped, reduced, and sharpened to post here, was taken on December 21, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a typical example of the kind of glacial feature found. The white cross on the map marks its location, west of the Hellespontus Mountains that form the western rim of Hellas Basin.

Scientists have dubbed this feature concentric crater fill, a purposely vague term because — though it looks like glacial fill — until there is data to confirm it the scientists would quite properly rather not commit themselves. The concentric rings suggest multiple layers, each of which likely marks a different climate cycle in Mars’ geological history.

In this case the glacier features also appear to cover the entire plain surrounding the crater as well as its rim. The small crater to the west is similar, and both give the appearance that the ice sheet that covers them came after the impact, draping itself over everything, with the craters only visible because the ice sheet sags within their interiors.

More crazy features from the cratered highlands to come.

First binary quasar found

9:48 am

Double quasar as seen by the Hubble Space Telescope
Double quasar as seen by the Hubble Space Telescope

Using a suite of telescopes on the ground and in orbit, astronomers have found the first galaxy made up of two quasars, supermassive black holes that are very active in eating material from around them.

ESA’s (European Space Agency) Gaia space observatory first detected the unresolved double quasar, capturing images that indicate two closely aligned beacons of light in the young universe. Chen and his team then used NASA’s Hubble Space Telescope to verify the points of light were in fact coming from a pair of supermassive black holes.

Multi-wavelength observations followed; using Keck Observatory’s second generation Near-Infrared Camera (NIRC2) paired with its adaptive optics system, as well as Gemini North, NASA’s Chandra X-ray Observatory, and the Very Large Array network of radio telescopes in New Mexico, the researchers confirmed the double quasar was not two images of the same quasar created by gravitational lensing.

The two quasars are estimated to be only about 10,000 light years apart. Scientists estimate that this galaxy is about ten billion light years away, and exists in this state only about three billion years after the Big Bang.

Shetland Spaceport now faces same regulatory hurdles that destroyed Virgin Orbit

9:37 am

The new Shetland spaceport, Saxavord, is right now attempting to get launch approvals from United Kingdom’s Civil Aviation Authority (CAA), the same agency that dithered for six months approving a Virgin Orbit launch, thus causing the bankruptcy of that company.

According to Saxavord’s CEO, the spaceport has two launches aiming to launch before the end of this year, assuming the CAA can get its act together and give its approval. This quote however is worrisom:

The Saxavord spaceport says it is “still on track” to receive its necessary licences from the sector’s regulator before the summer. This relates to applications to the Civil Aviation Authority for range and spaceport licences.

Meanwhile SaxaVord CEO Frank Strang said the company is also on track for two rocket launches this year – “albeit they have moved slightly to the right”. [emphasis mine]

The delays could be coming from the rocket companies themselves. One of those companies is the German startup, Rocket Factory Augsburg, which has leased exclusive use of one launchsite. The other is the American startup ABL, which has had one launch attempt from the U.S. that failed.

Based on the CAA’s track record however the delays are just as likely coming from it. The CAA began this licensing process in November 2022, and is not done yet six months later.

Scientists try to model what would happen if Ryugu hit Earth

9:19 am

Ryugu's northen hemisphere
Ryugu’s northen hemisphere. The arrow marks the spot Hayabusa-2
gathered samples

Scientists, using the data and rock samples gathered by the Japanese probe Hayabusa-2, have attempted to predict what what would happen if the rubble-pile asteroid Ryugu hit the Earth.

Without diversion intervention, Tanaka explained, if the Ryugu asteroid was heading to Earth and entered the planet’s atmosphere at an angle of 45 degrees and at a speed of around 38,000 miles per hour (17 kilometers per second), the rubble pile asteroid would break up at an altitude of around 25 to 21 miles (40 to 35 km) over the surface of the planet.

This would result in an “airburst” similar to that seen over Russia in February 2013 when the Chelyabinsk meteor erupted at an altitude of around 19 miles (30 kilometers) over Earth. The result of the Chelyabinsk blast was a bright flash of light and an atmospheric blast equivalent to the detonation of 400–500 kilotons of TNT. This is as much as 33 times the energy released by the atomic bomb that devastated Hiroshima at the end of the Second World War.

The Chelyabinsk meteor caused about 1,500 injuries, mostly from people injured by glass thrown out by breaking windows when it suddenly and unexpectedly exploded during re-entry. With Ryugu this would not be a surprise, so these injuries could be reduced, though not eliminated. The damage and injuries from pieces that survived the breakup and hit the ground remains unknown because scientists don’t know how much of the asteroid would survive the break up.

Ryugu of course poses no threat, because it is not on a collision course with Earth. Whether an asteroid like Ryugu could be diverted however remains unknown, since any such diversion must not cause the asteroid to break apart as well.

The outermost edge of Mars’ north polar icecap

The outermost edge of Mars' north polar icecap
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on February 4, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the terminating cliffs of the north pole ice cap of Mars, dubbed Rupes Tenius on this side of the icecap.

At this point the elevation difference of the icecap’s edge from top to bottom is not significant, only about 1,500 feet or so, though this is a very rough estimate. As with all other images of the ice cape’s edge, there are many many layers visible, all indicating a different cycle in the climate history of Mars as its rotational tilt swings from about 11 degrees to 60 degrees over eons.

Moreover, at this point there is likely not that much difference between the terrain on top and the terrain below. Both will be mixed ice and dust and coarse rocks, though the percentages will be shifting towards less ice as we go down.

FAA issues travel advisory for Boca Chica for April 10, 2023 Starship launch

10:30 am

Though the FAA has not yet issued the launch license to SpaceX, allowing it to do the first orbital launch test of its Superheavy/Starship rocket, the agency today did issue a travel advisory for the Boca Chica area for April 10-11, 2023, in connection with this launch.

The FAA advisory is here. Scroll down to see the space activities section, which includes this information:

SPACEX STARSHIP SUPERHEAVY BOCA CHICA, TX
PRIMARY: 04/10/23 1310-1745Z
BACKUP(S): 04/11-12/23 1310-1745Z

Based on this information, we should expect the FAA launch license to be publicly announced any moment.

English company buys land in Ohio for astronaut training facility

9:04 am

Blue Abyss, an English company focused on establishing “extreme environment research, test, and training centres,” has purchased twelve acres in Ohio where it plans to build an astronaut training facility.

The property, which is near Cleveland’s NASA Glenn Research Center, will include a 164-foot deep pool, microgravity center, astronaut training center, and a hotel. Brook Park Mayor Edward Orcutt described the facility as a “boot camp for astronauts.”

It appears the company is expecting there to be a lot of commercial astronauts in the coming years who will need training, and anticipates that NASA will not be capable of or interested in providing the service.

Lockheed Martin picked by Australia to build two military communications satellites

8:54 am

Australia’s military announced yesterday that it has chosen Lockheed Martin as the “preferred bidder” to build two military communications satellites.

According to Australian media reports, the ADF [Australian Defense Force] is interested in buying at least two geostationary communications satellites and wants a sovereign military satcom capability. Currently Australia’s defense forces rely on commercial satellite services and on the U.S. Wideband Global Satcom constellation. Air Vice-Marshal David Scheul, head of Australia’s Air Defence and Space Systems Division, said the project will deliver the country’s “first sovereign-controlled satellite communication system over the Indo-Pacific ocean regions.”

Lockheed Martin edged out competing teams led by Airbus, Boeing, Northrop Grumman and Australia’s largest satellite operator Optus.

To get the contract, Lockheed Martin partnered with almost a dozen Australian companies. The specifics of the deal however still have to be worked out.

Virgin Orbit files for bankruptcy

8:46 am

Less than a week after it laid off 85% of its workforce, Virgin Orbit’s management has filed for Chapter 11 bankruptcy.

Under Chapter 11, it appears the company can still be purchased and re-established, much like Firefly Aerospace was when it filed for bankruptcy. Since Richard Branson’s Virgin Group pumped a lot of cash into the company in the past six months, exceeding $70 million, it would get first crack at ownership rights. We should therefore not be surprised if Virgin Orbit comes back to life, owned by Branson and bought for pennies on the dollar, with the little stockholders and investors left in the lurch.

A journey into Martian chaos

5:12 pm

Overview map of Aram Chaos

With today’s cool image, we shall begin with the overview map, and drill our way down until we get a close look at another example of truly alien Martian terrain, with only a hint of similarity to comparable geology on Earth.

The overview map to the right shows us Aram Chaos, an ancient 170-mile-wide impact crater that has gone through such complex geology that it is difficult, maybe impossible, to unravel it based on data obtained from orbit. As I wrote in a detailed December 2020 post describing the confusing geology of this crater,

The floor of Aram Chaos is a place of great puzzlement to planetary geologists. The geology there is incredibly complex, and includes chaos terrain overlain by several sedimentary layers of sulfate minerals. The chaos terrain is most obvious in the southern part of the crater’s floor. The flat areas near the eastern center are those overlaying sedimentary layers.

When we zoom into the white box we can see a good example of this complexity.

Ingenuity completes 49th flight on Mars

1:37 pm

Overview map
Click for interactive map.

The Ingenuity team today posted the official flight totals for the Mars helicopter’s 49th flight, which took place yesterday.

The helicopter flew 925 feet for 143 seconds, or two minutes and twenty-three seconds. The plan had been to fly 894 feet for 135 seconds, but has been happening consistently for the past dozen or so flights, the helicopter spent a little more time in the air and traveled a little farther.

As for altitude, it apparently did exactly as planned, averaging about 40 feet in height until the end of the mission, when Ingenuity went straight up another twelve feet to get a wider view of its landing area.

The map to the right shows the context. The green dot marks Ingenuity’s location at the start of the flight. The green line indicates my approximate estimate of its flight path and landing area, which the engineering team has not yet posted. The white dots and line mark Perseverance’s path, with its present location at the area dubbed Tenby where it has obtained its first core sample from the top of the delta.

Sunspot update: Activity remained high in March

12:35 pm

It is time for my monthly sunspot update. NOAA this week updated its graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. This graph is posted below, with some additional details included to provide some context.

Last month the number of sunspots dipped slightly after a gigantic leap of activity in January. This month showed a small rise in activity, but not enough to bring levels back to the January’s levels. Nonetheless, activity remains the highest seen since 2014. when the last solar maximum was approaching its end, and continues to exceed significantly the 2020 prediction by NOAA’s panel of solar scientists.

NASA names four astronauts to fly on first manned Artemis mission around Moon

9:23 am

NASA today named the four astronauts who will fly on its Artemis-2 in a 10-day mission around the Moon, launched on SLS’s second launch in an Orion capsule and tentatively scheduled for late 2024.

The crew assignments are as follows: Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist 1 Christina Hammock Koch, and Mission Specialist 2 Jeremy Hansen. They will work as a team to execute an ambitious set of demonstrations during the flight test.

The approximately 10-day Artemis II flight test will launch on the agency’s powerful Space Launch System rocket, prove the Orion spacecraft’s life-support systems, and validate the capabilities and techniques needed for humans to live and work in deep space.

The flight, set to build upon the successful uncrewed Artemis I mission completed in December, will set the stage for the first woman and first person of color on the Moon through the Artemis program, paving the way for future for long-term human exploration missions to the Moon, and eventually Mars. This is the agency’s Moon to Mars exploration approach. [emphasis mine]

The highlighted words illustrate some important facts. First, this first manned flight of Orion will also be the first that will use the capsule’s life-support systems, which were not included the first flight around the Moon in December. Thus, these four humans are essentially guinea pigs for this engineering. Seems such a plan should have been questioned by NASA’S corrupt safety panel, but then, it is corrupt, and never seems to have much problem with unsafe practices done by NASA itself. Instead, it spends a lot of time making up problems for SpaceX and missing problems at Boeing and NASA.

Second, note NASA’s emphasis on race and sex for the first landing on the Artemis-3 mission. Note too that Artemis-2 crew also includes a black and a woman. Though the press release wisely and correctly makes no mention of race when describing the four astronauts, it does tout the achievements of Christina Koch as a woman, not as a person.

Don’t get me wrong. It is good that a black and a woman are flying to the Moon. It just appears very clear that NASA now has a firm quota system, requiring one of each for every mission.

Finally, there is something not mentioned in the press release or on the Artemis-2 webpage that is very telling. Neither says anything about a launch date, which NASA had previously announced as November 2024. I have been predicting from the beginning that this date is a fantasy. It now appears NASA realizes it but is not yet ready to admit it publicly.

Starship and Superheavy readied for orbital flight

10:22 am

With Superheavy prototype #7 already on the launchpad at Boca Chica, Texas, SpaceX engineers yesterday moved Starship prototype #24 beside it in preparation for stacking the orbital spacecraft on top of Superheavy for a launch now expected no earlier than April 10, 2023.

As the article notes, when Superheavy lifts off, it will set a new record for the most powerful rocket, having twice the thrust of either of NASA’s Saturn-5 or SLS rockets. And this record will be achieved by a privately built and owned rocket whose development has been funded almost entirely by private investment capital. Note too that the development took about six years, from concept to first launch, a few years less than it took NASA to build the Saturn-5 in the 1960s, and about one third the time it NASA to do the same thing with SLS in the 2000s, the 2010s, and the 2020s.

The orbital mission, it successful, will have Superheavy lift off, separate from Starship and then land controlled in the Gulf of Mexico. Starship will continue into orbit, and then attempt a controlled vertical splashdown in the Pacific Ocean northwest of the big Island of Hawaii.

At the moment, it appears the only obstacle to launch remains the FAA, which after many months has still not issued the launch license. This new activity at Boca Chica however suggests SpaceX expects that approval to occur momentarily.

Japan officially delays next H2A rocket launch because of H3 launch failure

10:07 am

Japan’s space agency JAXA has now officially delayed its next H2A rocket launch, scheduled for May and carrying a Japanese lunar lander dubbed SLIM, because that rocket shares some components of Japan’s new H3 rocket, which failed during its inaugural launch in March.

No new launches are currently planned after a series of setbacks for the Japan Aerospace Exploration Agency, including the next-generation H3 rocket’s failure and that of the smaller Epsilon-6 in October, which was ordered to self-destruct after deviating from its intended trajectory shortly after takeoff.

The earliest the H2A launch can be rescheduled for is August, due to the orbital mechanics for getting it to the Moon. There are indications however that even this date will not be met.

India successfully lands its own version of the X-37B on a runway

10:00 am

LEX landing

India’s space agency ISRO today successfully landed its own version of the X-37B on a runway.

The flight was a test of the landing system. The spacecraft, dubbed LEX, was dropped from a helicopter at an elevation of 2.8 miles above sea level. It then autonomously guided itself to the runway to land smoothly. The picture to the right shows LEX as it approaches the runway. Note how similar it looks to the X-37B.

ISRO had demonstrated the re-entry of its winged vehicle RLV-TD in the HEX mission in May 2016. … In HEX, the vehicle landed on a hypothetical runway over the Bay of Bengal. Precise landing on a runway was an aspect not included in the HEX mission. The LEX mission achieved the final approach phase that coincided with the re-entry return flight path exhibiting an autonomous, high speed (350 kmph) landing.

The next step will of course be to launch an orbital version, and bring it back to Earth for reuse.

SpaceX and Chinese pseudo-company complete launches

9:46 am

Two launches today. First, a new Chinese pseudo-company, dubbed Space Pioneer, completed the first launch of its liquid kerosene-fueled Tianlong-1 rocket, putting a military surveillance satellite into orbit.

Space Pioneer is the third Chinese pseudo-company to achieve orbit, but the first to do it with a liquid-fueled rocket. The previous two, Ispace and Galactic Energy, used solid-fueled rockets based on military missile technology. All of these Chinese companies follow a private model. An individual or a group of individuals creates the company, obtains private investment capital, and then wins contracts from the Chinese government. What makes them pseudo is that they do not work independently and freely, and really do not own their products. The Chinese government supervises and approves everything, and can take over at any time.

The second launch today was by SpaceX, using its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California to put a new smallsat constellation of ten military satellites, designed to test the quick development (under two years) of such smallsats for use by the military.

The first stage successfully completed its second flight, landing back at Vandenberg. The fairings completed their fourth and sixth flights, respectively.

The leaders in the 2023 launch race:

22 SpaceX
14 China
6 Russia
3 Rocket Lab

American private enterprise still leads China 25 to 14 in the national rankings, and the entire world combined 25 to 24. SpaceX by itself trails the entire world, including American companies, 22 to 27.

Stratolaunch’s Roc airplane completes another test flight

9:31 pm

Stratolaunch today announced that it has successfully completed the third capture-carry test using its giant Roc airplane, carrying an engineering test version of its Talon vehicle, designed to do hypersonic flight tests for the Air Force.

The flight was the tenth for the company’s launch platform Roc and marks the beginning of routine flight operations in Vandenberg Space Force Base’s Western Range off California’s central coast. The flight, which lasted a total of five hours, performed risk reduction by practicing a variety of separation profiles and confirming telemetry between Roc and Talon-A vehicles and Vandenberg Space Force Base’s communication assets, assuring that back-up telemetry data collection will occur during future flight tests.

Pending results of post-flight data analysis, the team will progress toward a separation test in the coming weeks, enabling the company to perform its first hypersonic flight in 2023.

There is a lot of potential test capability for Roc and Talon, not just with hypersonic missiles and aircraft. If Stratolaunch succeeds in fulfilling this Air Force contract, it will likely garner a good amount of additional business.

Lunar rover startup signs deal to send rover to the Moon using Starship

9:25 pm

The lunar rover startup Astrolab has signed a deal with SpaceX to send its FLEX rover to the Moon’s south pole region using a lunar lander version of Starship.

Jaret Matthews, founder and chief executive of Astrolab, said in an interview that the mission, which will include 1,000 kilograms of customer payloads, will be the first flight of the FLEX rover. It will be a rideshare payload on a Starship mission landing somewhere in the south polar region of the moon.

“Because our rover can traverse up to a couple thousand kilometers in a given year, we’re less sensitive to exactly where we land,” he said. “’It is definitely optimized for the south polar region because that’s fundamentally where we think that the bulk of the activity is going to be.”

The company unveiled a full scale prototype of its rover one year ago, when it made it clear it intended to compete for the rover contract in NASA’s Artemis program, competing against several big established players. Since then there has been little news. The story today sadly reeks to me of a lot of blarney. For example, the company has only 20 employees. Astrolab might have signed this deal, but I suspect it is a very tentative deal, easily canceled by either party at no cost.

Update on MOXIE’s two years on Mars, producing oxygen

9:17 pm

Link here. MOXIE is a technology test instrument on the rover Perseverance that has proven it will be possible to practically produce sufficient oxygen from the Martian atmosphere to sustain a human colony.

The link provides a nice summary of everything the engineering team has accomplished since Perseverance landed in testing this technology. As I wrote in my December post about MOXIE’s achievements:

Based on these tests, MOXIE has unequivocally proven that future human explorers will not need to bring much oxygen with them, and will in fact have essentially an unlimited supply, on hand from the red planet itself. More important, MOXIE has also proven that the technology to obtain this oxygen already exists.

All we need to do is plant enough MOXIE trees on Mars.

Sponge terrain on Mars

Sponge terrain on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on January 11, 2023 by the high resolution camera on Mars Reconnaissnace Orbiter (MRO).

The scientists labeled this picture “Rocky Terrain.” Though this describes the overall sense of the full image, it fails to capture correctly the nature of this patch of ground at the center of the picture. As you can see, this patch of spongelike surface starts and ends abruptly. It appears that it is a layer on top of the surrounding terrain that has also been eroded aggressively since its placement.

The many craters on its surface seem to have come later, though as the crater size diminishes it becomes harder to separate the craters from the sponge holes. Moreover, some of the larger craters are distorted in shape, as if the impact hit material that was viscous and could flow somewhat.

The overview map below gives some context, but only some.

Spain’s government officially establishes a Spanish space agency

9:41 am

Spain’s Council of Ministers has voted to officially established a Spanish space agency, with operations beginning on March 7, 2023 with an initial budget of $753 million.

This announcement comes only a month before the private Spanish company, PLD, attempts its first suborbital launch from a Spanish spaceport of its Miura-1 rocket, its first stage designed to come back to Earth by parachute, recovered, and then reused. If successful the company hopes to then develop an orbital version.

The news from Europe increasing suggests that the members of the European Space Agency (ESA) are beginning to go their own way, relying less upon it. In addition to these developments in Spain, Germany now has three private companies developing rockets while Italy’s government has provided $308 million to its own Italian rocket company Avio. The United Kingdom meanwhile has had its own space agency for several years, is building several spaceports, and has been trying to develop its own space industry, with very mixed results. In addition, both Norway and Sweden are building spaceports for commercial operations.

ESA, while mouthing support for commercial space, has so far not done well in the past decade in transitioning from a government run, built, and owned operation to one owned by commercial companies. Its new Ariane-6 rocket, built and controlled by ArianeGroup but heavily managed by ESA, is still too expensive to compete with the new commercial rockets from the U.S. Nor does it appear ESA is moving very fast to fix this situation. It appears many people in Europe have recognized this state of affairs, and are looking for alternatives.

Two launches by China

China’s spaceports

China yesterday and today successfully completed two launches using two different rockets from two different spaceports.

First, a Long March 2D rocket yesterday launched a set of four satellites establishing a new constellation of radar satellites designed to measure the Earth’s surface topography. Lift off was from the Taiyuan Satellite Launch Center in the northeast of China. No word on where the rocket’s first stage crashed.

Next, a Long March 4C rocket today placed in orbit a classified military “remote-sensing” satellite, lifting off from the Jiuquan Satellite Launch Center in China’s northwest. Once again, no information was released on where the first and second stages of the rocket crashed to Earth.

The leaders in the 2023 launch race:

21 SpaceX
13 China
6 Russia
3 Rocket Lab

American private enterprise still leads China 24 to 13 in the national rankings, and the entire world combined 24 to 23. SpaceX now trails the entire world combined, including American companies, 26 to 21.
