Europe and China discussing future space cooperation

The new colonial movement: The heads of the space agencies of both Europe and China held a virtual face-to-face discussion on April 1st, discussing their space operations as well as the possibility of future cooperation.

Zhang Kejian, administrator of the CNSA, and new ESA Director General Josef Aschbacher, who entered the post March 1, discussed a range of topics according to a short CNSA press release (Chinese). The parties outlined upcoming activities, with China recently approving a 14th Five-year plan for 2021-2025, and discussed lunar and deep space exploration, Earth observation, and cooperation in ground station.

Josef Aschbacher tweeted after the meeting that he had congratulated Zhang on the Chang’e-5 lunar sample return mission, which in December 2020 delivered to Earth 1.73 kilograms of lunar samples from Oceanus Procellarum on the moon’s near side.

…Karl Bergquist, ESA’s international relations administrator, told SpaceNews that ESA and CNSA went over ongoing activities including telemetry, tracking, and control support activities for the Chinese exploration program.

Apparently Zhang raised the issue of Europe contributing to China’s proposed lunar base. Aschbacher made no commitments, though he later stated that while there is “no ESA stance on this topic”, he anticipates future discussions on the topic.

Some of this is similar to the recent discussions between NASA and China, focused on exchanging telemetry of various orbiters to avoid the possibility of collisions or interference with their operation. I would not be surprised however if Europe expands this conversation and joins China in its space plans. The U.S. is shifting from a government-run space program — which both China and Europe favor — to a commercial model mostly run by private enterprise. Under that model there will be less opportunity for European participation in American space projects.

OSIRIS-REx completes last close-fly of Bennu

OSIRIS-REx today successfully completed its last close-fly of Bennu before it will fire its engines on May 10th and begin its journey back to Earth to return its samples.

During the flyby, OSIRIS-REx imaged Bennu for 5.9 hours, covering more than a full rotation of the asteroid. It flew within 2.1 miles’ (3.5 kilometers) distance to the surface of Bennu – the closest it’s been since the TAG sample collection event.

It will take until at least April 13 for OSIRIS-REx to downlink all of the data and new pictures of Bennu’s surface recorded during the flyby. It shares the Deep Space Network antennas with other missions like Mars Perseverance, and typically gets 4–6 hours of downlink time per day. “We collected about 4,000 megabytes of data during the flyby,” said Mike Moreau, deputy project manager of OSIRIS-REx at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Bennu is approximately 185 million miles from Earth right now, which means we can only achieve a downlink data-rate of 412 kilobits per second, so it will take several days to download all of the flyby data.”

While they will get images of the asteroid’s entire surface, the region scientists are most interested in is the Nightingale sample return site where the spacecraft grabbed its samples. To best understand the asteroid they need to have before and after shots, and this last fly-by gave them the latter.

Perseverance as seen from orbit

Perservance on the ground

Cool image time! The two photos to the right show the landing site for the Perseverance rover in Jezero Crater on Mars. The first image was taken in 2016 by the high resolution camera on Mars Reconnaissance Orbiter. The second image was made available today in the monthly release of photos taken that camera on MRO.

The arrow points to a small white streak that is not visible in the 2016 photo. A closer look reveals that the streak is actually two fanlike white deposits expanding outward in opposite directions from a central point.

What we are seeing are the exhaust fans blown onto the Martian surface by the retro-jets on the Sky crane that was lowering Perseverance to the ground. The rover was put down at the centerpoint, and was still at that spot on March 2nd when this photo was acquired.

The highest resolution version of this image requires special software, so in this version you cannot see the rover itself. Nor can you see the Sky crane after it crashed landed or the parachutes.

The new photo was taken one week after the first high resolution image from MRO, as part of what will become a routine periodic monitoring of the site, along with obtaining mapping information for picking the rover’s upcoming route They will also probably use both images to try to locate both the Sky crane and parachutes, on the ground.

SpaceX successfully launches another sixty Starlink satellites

Falcon 9 today, with booster on 7th flight

SpaceX this morning successfully launched another 60 Starlink satellites, bringing the total number in orbit to more than 1,500.

The first stage, on its seventh flight, successfully landed on the drone ship. During SpaceX’s live stream they noted that every launch by the company this year has used a previously flown first stage. Both fairings on this flight were also reused.

The leaders in the 2021 launch race:

10 SpaceX
7 China
5 Russia
2 Rocket Lab

The U.S. now leads China 14 to 7 in the national rankings.

I have embedded SpaceX’s live stream below the fold. Because of the clear weather this was a particularly beautiful launch. The video during the landing of the first stage was especially spectacular, with the camera on the booster showing the entire landing.

Watching Ingenuity’s flight

NASA has now announced the planned flight time for its Ingenuity helicopter now on the Martian surface, including information for watching the live stream of the attempt.

A livestream confirming Ingenuity’s first flight is targeted to begin around 3:30 a.m. EDT Monday, April 12, on NASA Television, the NASA app, and the agency’s website, and will livestream on multiple agency social media platforms, including the JPL YouTube and Facebook channels.

I will embed the JPL live stream on Behind the Black when it goes live.

Meanwhile, Perseverance’s weather station is now functioning, providing its first weather reports from Jezero Crater.

[E]ngineers now have atmospheric data from three different locations on the Red Planet – Perseverance, Curiosity, and NASA’s InSight lander, which hosts the Temperature and Wind sensors for InSight (TWINS). The trio will enable a deeper understanding of Martian weather patterns, events, and atmospheric turbulence that could influence planning for future missions. In the near term, MEDA’s information is helping decide the best atmospheric conditions for the Ingenuity Mars Helicopter flights.

As Ingenuity achieved pre-flight milestones, a MEDA report from the 43rd and 44th Martian days, or sols, of the mission (April 3-4 on Earth) showed a temperature high of minus 7.6 degrees Fahrenheit (minus 22 degrees Celsius) and low of minus 117.4 degrees Fahrenheit (minus 83 degrees Celsius) in Jezero Crater. MEDA also measured wind gusts at around 22 mph (10 meters per second).

Those numbers are about normal for Jezero Crater at 18 degrees north latitude in the spring.

Chang’e-4 and Yutu-2 reactivated for 29th lunar day

Chinese engineers have reactivated their Chang’e-4 lander and Yutu-2 rover, beginning their 29th lunar day on the far side of the Moon.

As is usual from the state-run Chinese press, the article provides little other detail, other than stating that Yutu-2 ” will continue to move northwest toward the basalt distribution area located about 1.2 km away from the rover.” That’s about 3,900 feet. Based on Yutu-2 pace of moving about 100 feet per lunar day, it will be more than three years before it reaches that goal.

Study: a Martian crater lake fed by glacial run-off

Map of crater lake and run-offs
From figure 1 on the research paper.

A new study of a 33-mile-wide Martian crater in its southern cratered highlands has found evidence that a lake had once existed on the crater floor, and was fed entirely by glacial run-off in a cold climate, coming from its interior walls, not from outside the crater.

In a study published in Planetary Science Journal, a research team led by Brown Ph.D. student Ben Boatwright describes an as-yet unnamed crater with some puzzling characteristics. The crater’s floor has unmistakable geologic evidence of ancient stream beds and ponds, yet there’s no evidence of inlet channels where water could have entered the crater from outside, and no evidence of groundwater activity where it could have bubbled up from below.

So where did the water come from?

The researchers conclude that the system was likely fed by runoff from a long-lost Martian glacier. Water flowed into the crater atop the glacier, which meant it didn’t leave behind a valley as it would have had it flowed directly on the ground. The water eventually emptied into the low-lying crater floor, where it left its geological mark on the bare Martian soil.

You can read the full paper here. The crater is considered very old, which means this evidence dates from a very early Mars when the climate was very different. As the scientists note in their conclusion:

SpaceX’s decision to build launchpad with Starship tanks proves the rocket will be cheapest ever built

Capitalism in space: The decision by SpaceX’s to build the tank farm for its Starship/Super Heavy launchpad at Boca Chica using Starship tanks, rather than inexpensive off-the-shelf storage tanks, strongly suggests that the company’s manufacturing facility for building those tanks makes them very inexpensive, and also suggests that the final rocket will be as cheap to launch as SpaceX has promised.

SpaceX is effectively taking identical rocket parts, slightly tweaking a handful of those parts, and turning what could have been a rocket into a propellant storage tank. This is significant because relative to all other rockets in history, even including SpaceX’s own Falcon 9 and Heavy, building storage tanks with unchanged rocket parts on a rocket assembly line would be roughly akin to hiring Vincent van Gogh to paint lane lines.

Ever since Elon Musk made the radical decision to switch from composite structures to stainless steel, Starship has always aimed to be radically different than any large rocket before it. Crucially, by using commodity steel, the CEO imagined SpaceX would be able to build Starships fairly easily and for pennies on the dollar next to even SpaceX’s exceptionally affordable Falcon 9. In the last 18 months, it’s become apparent that SpaceX has built a factory capable of churning out one or two massive steel rockets per month and is willing to consign at least four or five of those Starship prototypes to all-but-guaranteed failures for the sake of data-gathering and iterative improvement.

Technically, the most logical conclusion would be that Musk was right and that SpaceX has quickly developed the ability to build steel rockets larger than any other launch vehicle on Earth for perhaps just $5M or less apiece.

The analysis at the link is detailed and worth reading. If correct, this decision by SpaceX proves that Starship and Super Heavy will be the cheapest rocket ever flown, even though it will be the largest ever flown, and also completely reusable.

Russia’s first private space tourism company shuts down

Capitalism in space? Russia’s first private space tourism company has been forced to close before it even launched its first rocket because of the obstacles placed before by Russia’s government.

Kosmokurs’ operations will cease due to “insurmountable difficulties” in coordinating with local authorities on the cosmodrome project as well as the company’s “inability to obtain needed regulatory documents from the Defense Ministry” for the design of a suborbital tourist rocket, its CEO Pavel Pushkin told RIA Novosti.

However, the government-run Roscosmos, which controls the rest of Russia’s aerospace industry, has graciously announced it will hire Kosmokurs’ fifty employees.

Do you see a pattern? I do. Kosmokurs was cutting into Roscosmos’s territory. That could not be tolerated, and so the government moved to sabotage it. Now that it is dead, the government can absorb it to try to build its rocket and make money using it.

This kind of mob rule by the Russian government is why that country’s space industry is failing to compete with the new commercial industry coming out of the U.S. and elsewhere. It does not tolerate free competition, only top-down control by the government. The result is that while Russia might eventually fly its own space tourism rockets, it will have only one, and it will likely not be as efficient or as competitive. The only cost advantage it will likely have is Russia’s low wages.

Rocket startup ABL Space gets giant Lockheed Martin launch contract

Capitalism in space: Smallsat rocket startup ABL Space, which has yet to launch its first test rocket, has won a gigantic launch contract from Lockheed Martin for as many as 58 launches through 2029.

Under terms of the block-buy agreement between ABL Space Systems and Lockheed, the aerospace giant will purchase “up to” 26 launches through 2026 and as many as 32 additional launches through 2029. If the terms are fulfilled, this would come to 58 launches over the next eight years for ABL Space. In an industry where even a single launch contract often produces a news release, a contract for five dozen launches is unprecedented for a private company.

…The partnership will allow Lockheed, which builds large numbers of satellites for commercial customers, frequent and low-cost access to space. It is perhaps not a surprise that Lockheed selected ABL Space for its small launch needs, as Lockhead was an early investor in the launch company during a seed phase in 2019 and has continued to participate in additional rounds of fundraising. ABL has raised a total of $219 million to date.

Though Lockheed Martin is not ABL’s biggest investor, by being an early investor it has been involved in the development of ABL’s RS1 rocket from the start, which also means that Lockheed Martin was essentially buying its own rocket company to place the satellites it makes into orbit.

In fact, this decision falls into line with what appears to be Lockheed Martin’s long term corporate strategy. In 2017 the company opened its satellite-making factory with the satellites designed with standardized structures so that customers could pick and choose the design of their liking.

In 2018 it was revealed that the company was a key investor in Rocket Lab, while also participating in the creation of the United Kingdom’s first spaceport in Sutherland, Scotland.

It then decided to become a major investor in ABL, probably taking advantage of what it learned from Rocket Lab to improve the design. Now it plans to use that new rocket to launch a large number of the smallsats it is building in its factory.

Lockheed Martin is essentially copying SpaceX’s vertical integration strategy, whereby it owns or builds all aspects of its launch business. This allows it to reduce costs while controlling construction entirely. You cut out the middle man, and make your satellites cheaper to sell to others.

The first launch of ABL’s RS1 rocket was originally scheduled for the first half of this year, but has now been pushed back to the third quarter. If successful the company says it will follow it with two more launches before the end of the year, and very ambitious schedule.

Ingenuity survives first night on its own on Mars

Completing another a major engineering hurdle, the Ingenuity helicopter successfully survived its first night on Mars, unprotected by the power and shielding of the Perseverance rover.

“This is the first time that Ingenuity has been on its own on the surface of Mars,” said MiMi Aung, Ingenuity project manager at NASA’s Jet Propulsion Laboratory in Southern California. “But we now have confirmation that we have the right insulation, the right heaters, and enough energy in its battery to survive the cold night, which is a big win for the team. We’re excited to continue to prepare Ingenuity for its first flight test.”

Engineers will spend the next two days fine-tuning Ingenuity’s thermal and power systems. Then on April 7th they will begin testing the helicopter’s rotary blades and their motors. If all goes right, the actual flight will occur on April 11th.

Colorful mesa in the Martian northern lowland plains

Colorful mound in Martian northern lowland plains
Click for full image.

Cool image time! The photo to the right, rotated and cropped to post here and taken on January 15, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows the colorful top of a small mesa in the northern lowland plains of Mars and about 300 miles north of the planned landing zone for Europe’s Franklin rover, scheduled to launch in 2022.

What makes this mesa stand out is the bright and colorful areas on its slopes. The colors are false, but they indicate [pdf] certain things. The yellow is likely dust covered rock. The pinkish rock is also likely dust-covered, but made up of coarser material. The bluish strip running along the mesa’s northern slope is possibly frost or ice, not unlikely as this mound is at 25 degrees north latitude and was taken during winter. The slope faces north, which would put it in shadow much of the time during winter.

The colors however only hint at what is there.

Methane tank leak caused Starship #11 failure

Capitalism in space: According to Elon Musk, a small leak of methane from one tank caused the failure of the eleventh Starship prototype. From Musk’s tweet:

Ascent phase, transition to horizontal & control during free fall were good.

A (relatively) small CH4 leak led to fire on engine 2 & fried part of avionics, causing hard start attempting landing burn in CH4 turbopump.

This is getting fixed 6 ways to Sunday.

Meanwhile, prototype #15 is getting prepped for rollout to the launchpad (Numbers 12-14 were scrapped), and the first prototype of first stage Super Heavy is being assembled to testing. It is presently unclear when either will take place, though the company still has a target date of July for its first orbital launch. According to Musk, the first orbital prototypes of Starship will be those numbered 20 or higher.

“Those ships will be orbit-capable with heat shield & stage separation system,” Musk tweeted. “Ascent success probability is high. However, SN20+ vehicles will probably need many flight attempts to survive Mach 25 entry heating & land intact.”

Knowing those first orbital ships will likely not land properly raises the question as to where they will be aimed to come down. SpaceX now owns two retired floating oil platforms, and is preparing them for use by Starship/Super Heavy. It could very well be that test flights of prototype #20+ will take place to and from those pads, out in the ocean, so as to minimize any risk to populated areas. Doing so will also allow SpaceX to hone its procedures for moving these big spaceships to and from the platforms.

Resilience successfully moves from one ISS docking port to another

With four astronauts on board the Dragon capsule Resilience tonight successfully undocked from one docking port on ISS and redocked to a different port.

This was the first time an American spacecraft had accomplished this task. It was necessary to clear the docking port that the next Dragon capsule, Endeavour, will use to bring its crew to ISS, presently set for launch on April 22nd.

Russian astronauts have piloted Soyuz spacecraft between different ports numerous times, both on ISS and on Russia’s earlier space stations. Tonight’s transfer by Resilience however was done entirely on autopilot. The American astronauts could have taken over manually at any time, but the spacecraft did the entire maneuver on its own.

There is a certain irony in how the Russians have always done this maneuver, manually, and how Resilience did this, without any human intervention. From the 1960s through the entire space shuttle program Americans and all its astronauts strongly demanded that their spacecraft be piloted, by the humans on board, rather than being controlled by software or ground control. The Russians instead insisted, at least initially, that while their astronauts had the capability of doing all maneuvers manually, their software or mission control should run things. This difference seemed to nicely symbolize the down-up nature of America versus the top-down culture of Russia.

Things are now reversed. I wonder if that tells us anything about the two cultures today.

More leaks found in Russian Zvezda module on ISS

Earlier this week Russian astronauts located and patched three more leaks in the 20+ year old Russian Zvezda module on ISS.

Prior to this week’s discovery, the recent patching done by Russian astronauts had reduced the air loss by about half. They need to do another seal test of Zvezda to see if these newer patches have reduced it further.

The report at the link from Russia is as usual very vague. No photos of any of the leaks have been released, by either Russia or NASA. No cause either has been described. This lack of information suggests that the leaks represent a more systemic problem, possibly related to stress fractures from age and wear. If so, it also suggests that Zvezda is nearing its pull-date. How this central module will be replaced from the station remains a major mystery.

Above all, this puts some urgency to the launch of newer modules, such as those being built by the private company Axiom.

Ingenuity released from Perseverance

Perseverance engineers have now confirmed that the Ingenuity helicopter was successfully released below the rover earlier today, and the rover immediately moved away to expose the helicopter to sunlight so that its solar panels can charge its batteries.

The photo to the right, cropped to post here, was taken by one of Perseverance’s rear hazard avoidance cameras, shortly after the release and move. They will now begin about a week of check-outs to make sure Ingenuity is functioning properly, even as they drive Perseverance a distance away to a lookout point where it can safely observe the helicopter’s test flight on Mars, presently targeted for April 11th. If successful this will be the first powered flight ever achieved on another world.

Falcon 9 upper stage debris lands on Washington farm

Falcon 9 helium pressure tank
Click for full image.

When a Falcon 9 upper stage broke up over the Pacific northwest last week apparently one of its interior helium pressure tanks, used to help push the fuel or oxidizer from the larger tank during launch, fell on a Washington farm and has since been recovered.

The image to the right is that tank, in what appears to be remarkable shape. From the article:

Composite-overwrapped pressure vessels, or COPVs, are standard components in Falcon 9 rockets. They’re designed to hold the helium gas that’s used to pressurize propellant tanks. COPVs are likely candidates to survive re-entry because they’re relatively lightweight and heat-resistant.

The tank has been returned to SpaceX, which I am sure is going to be very interested in studying its condition very thoroughly.

Russian gov’t okays extension of U.S cooperative space treaty to ’30

The Russian government yesterday officially approved an extension to 2030 of the cooperative space treaty with the United States that was initially signed in 1992.

According to the TASS article at the link, the U.S. government has already approved this extension. The original agreement was for U.S. flights to the Russian space station Mir. It has been renewed four times since to cover the deal to build and use ISS.

This could very well be the last extension of this deal. By 2030 private commercial American stations should be operational, and the age of some of the oldest sections of ISS will likely need replacement. At that point the U.S. will probably decide to retire its half of ISS.

What the Russians will do is uncertain. The government doesn’t have the cash to build its own station. Nor has that government allowed a private commercial space industry to thrive and thus be financially able to build private commercial stations. Russia may separate its part of ISS and attempt to keep it aloft, but some of their modules are the oldest, and have shown signs of that age.

Two pits at opposite ends of Mars’ big volcanoes

Overview map

Regular readers of Behind the Black know that since 2018 I have regularly documented all the images of pits taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO). (See my last pit post in January for a full list of these previous articles.) The black dots on the map to the right shows the location of all the pits near the volcanoes Arsia and Pavonis Mons that have so far been highlighted here.

The two white dots are the two most recent MRO pits, and are the subject of today’s cool image. They also happen to be the farthest north and south pits so far documented. The southernmost pit, which I am saving till last, is the most interesting.

InSight detects additional 3+ magnitude quakes on Mars

Martian quake map as seen by InSight

According to a JPL press release today, the seismometer on the Mars lander InSight detected two new 3+ magnitude quakes in March, both coming from the Cerberus Fossae region, the same region where the bulk of seismic activity has so far been pinpointed on Mars.

The map to the right was presented several weeks ago at the 52nd Lunar and Planetary conference, and could possibly include one of these two new quakes. The timing however of these March quakes is significant:

The new quakes have something else in common with InSight’s previous top seismic events, which occurred almost a full Martian year (two Earth years) ago: They occurred in the Martian northern summer. Scientists had predicted this would again be an ideal time to listen for quakes because winds would become calmer. The seismometer, called the Seismic Experiment for Interior Structure (SEIS), is sensitive enough that, even while it is covered by a dome-shaped shield to block it from wind and keep it from getting too cold, wind still causes enough vibration to obscure some marsquakes. During the past northern winter season, InSight couldn’t detect any quakes at all.

They are beginning to use the lander’s scoop to cover the seismometer and its communications tether with sand to protect both from the wind and temperature fluctuations. Once done they hope to be able to detect quakes during the entire Martian year, though this ability will be further limited by a reduction in power.

Despite the winds that have been shaking the seismometer, InSight’s solar panels remain covered with dust, and power is running lower as Mars moves away from the Sun. Energy levels are expected to improve after July, when the planet begins to approach the Sun again. Until then, the mission will successively turn off the lander’s instruments so that InSight can hibernate, waking periodically to check its health and communicate with Earth. The team hopes to keep the seismometer on for another month or two before it has to be temporarily turned off.

Tianwen-1’s engineers set mid-May for rover landing on Mars

The new colonial movement: The science team for China’s Tianwen-1 orbiter are now targeting mid-May for when they will release and land the as-yet unnamed rover for its landing on Mars.

Wang Chi, director of the National Space Science Center at the Chinese Academy of Sciences, said March 23 that Tianwen 1’s lander and rover are scheduled to touch down on Mars in May.

“The first Chinese Mars mission, Tianwen 1, is now orbiting Mars, and we are landing in the middle of May,” Wang said in a presentation to the National Academies’ Space Studies Board. “We are open to international cooperation, and the data will be available publicly soon.” [emphasis mine]

Though China has generally released the scientific data of its lunar probes eventually, they have done it slowly. In the case of Tianwen-1, they released so far practically nothing, with the only images released being two hi-resolution ground images and a handful of distant global pictures of Mars.

Very peculiar flow features on Mars

Peculiar flows on Mars

Today’s cool image focuses on one of the weirdest flow features I have yet seen on Mars. The first photo to the right, rotated and cropped to post here, comes from a January 27, 2021 picture by the high resolution camera on Mars Reconnaissance Orbiter (MRO). This cropped section focuses on the middle of three such weird features, two close flows heading downhill on the interior rim of very eroded 28-mile-wide crater. For some reason the flows also have depressions on their crowns. The depressions almost look like someone carved them out with a spackling spatula. In fact, the MRO science team agrees, labeling this image as “Spatulate Depressions with and without Upslope Gullies.”

The second image to the right shows a wider crop of the same picture, and explains the reason for the last half of that label.

Click for full image.

The photo to the right, taken yesterday, shows Perseverance’s Ingenuity helicopter now vertical with its legs deployed, hanging from the bottom of the rover and ready for placement on the ground.

The next step will be drop Ingenuity those last few inches. Once released Perseverance will quickly drive away, as it will no longer be providing power to the helicopter and will instead be blocking its solar panels from sunlight.

Perseverance will then proceed to its lookout post while engineers check out Ingenuity to make sure all is working.

The targeted flight date remains April 8th.

UPDATE: JPL just announced that it is delaying Ingenuity’s flight to April 11th. The announcement was done by a tweet, so provided no explanation as to why JPL decided to delay three days.

Sierra Nevada will build space stations and a manned version of Dream Chaser

Sierra Nevada's proposed LIFE space station
Artist conception of Sierra Nevada’s LIFE space station

Capitalism in space: Sierra Nevada announced today that it will not only build a manned version of its Dream Chaser reusable mini-shuttle, it now intends to use that shuttle as a ferry to its own space station, made up of inflatable modules.

They have dubbed their proposed station LIFE, and describe as follows:

The LIFE habitat is a three story, 27-foot large inflatable fabric environment that launches on a conventional rocket and inflates on-orbit. The LIFE habitat is undergoing a NASA soft-goods certification this year and the full size ground prototype developed under NASA’s NextSTEP-2 contract is in the process of being transferred from Johnson Space Center in Texas to Kennedy Space Center in Florida for further testing on short-and long-term habitation. SNC’s Astro Garden® system also provides fresh food within the habitat.

Making a manned version of Dream Chaser was always expected. Adding the company’s own station makes complete sense. Except for the rocket to launch a Dream Chaser spacecraft, Sierra Nevada will be able to provide a full service experience to, in, and from space.

Shetland spaceport application rejected by local monument authority

The application to build a spaceport on one of the Shetland Islands has been rejected by a local monument authority because it would cause “extensive and adverse impact on the cultural significance” of a WWII radar station.

Mr Strang [head of the spaceport organization] said he was “greatly surprised” by the decision, claiming HES [Historic Environment Scotland] had “done nothing to preserve the site for the last 50 years”.

Skaw is the UK’s most northerly Second World War radar station and protected as a scheduled monument of national importance. The proposed space centre would be built almost entirely with in the RAF radar station site. It would require the removal of nine buildings, including air raid shelters, guard huts and those associated with the radar system. More than 200 archaeological features, such as foundations of buildings, gun emplacements and bomb craters would also be removed.

The Shetland Islands are very remote with few job opportunities for its residences. Putting a spaceport there seems like an excellent idea, especially because it will create hundreds of jobs where none exist now.

The radar facility did the same, but it did so more than seventy years ago, during World War II. Protecting these old and unused buildings for the sake of those long gone jobs seems utterly foolish.

The spaceport people say they will oppose this decision, but it is not clear from the article what they can do. The law as written appears to give this historical agency full power to veto.

Ice under Mars’ biggest volcanic ash field, at the equator?

Wind eddies on Mars
Click for full image.

According to new data obtained from the radar instruments on Mars Reconnaissance Orbiter (MRO) and Mars Express, scientists now think that the Medusae Fossae Formation, Mars’ biggest volcanic ash field and thought by some to be the source of most of the planet’s dust, might have an underground layer of ash that is also ice-rich. From their abstract:

The Medusae Fossae Formation (MFF) on Mars covers a vast area along the boundary between the rugged southern highlands and the smooth northern plains. While the MFF appears to be thick sediments or volcanic ash slowly eroding in the martian winds, how this material was emplaced remains mysterious. Most intriguing is evidence suggesting that some areas of the MFF may contain water ice. In this work we use sounding radar data from the SHARAD instrument on the Mars Reconnaissance Orbiter to probe up to 600 m below the surface and measure the electrical properties of the MFF material. The results suggest that the shallow parts of the MFF deposits are very porous and compress readily under their own weight. To match deeper probing by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument on Mars Express requires a second layer of either vast porous deposits or ice‐rich material protected from sublimation by the dry sediments.

The MRO image above, originally posted here in November 2020, shows one example of the typical wind erosion found in the Medusae ash field. Apparently the ground-penetrating radar from orbit now suggests the possibility that there is an ash layer rich in ice, at depths beginning somewhere between 1,000 to 2,000 feet below the surface.

FAA says it will “lead” investigation into Starship #11 crash yesterday

They’re coming for you next: The Federal Aviation Administration (FAA) announced today that it will “oversee” the investigation into the crash at landing yesterday by SpaceX’s eleventh Starship prototype.

The Federal Aviation Administration, which had an inspector at SpaceX’s facilities to observe the test flight, said in a statement that the FAA will oversee the company’s investigation into the “prototype mishap.” The FAA has conducted similar mishap investigations after previous Starship test flights. “The [Starship] vehicle experienced an anomaly during the landing phase of the flight resulting in loss of the vehicle,” an FAA spokesperson said. “The FAA will approve the final mishap investigation report and any corrective actions SpaceX must take before return to flight is authorized.”

The FAA noted that it will also work with SpaceX to identify reports of light debris in the area, saying that there have yet to be any reported injuries or damaged to public property.

What will really go on here is that an FAA official will observe closely as SpaceX conducts the investigation. That official might have some background in space engineering, but he or she will be completely unprepared to actually lead the investigation. Thus in the end the FAA will really only be able to rubber stamp SpaceX’s conclusions, though it might as all governments do, demand its own pound of flesh before issuing that stamp.

Up to now the FAA has tried very hard to work with the new commercial space companies, especially SpaceX, doing as little as it can to impede their progress. There are strong signs however that this might now change with the Democrats in control of the White House and Congress. If so, expect the FAA to cause SpaceX some grief during this investigation, grief that could significantly delay further test flights.

Three new German smallsat startup rocket companies vying for market share

Capitalism in space: Three new German startup companies have joined the race to grab a share in the burgeoning new cubesat/nanosat launch business, with each building their own new rockets.

The companies are dubbed Isar Aerospace, Rocket Factory, and HyImpulse..

Each is developing rockets capable of carrying between 500 and 1,500 kilos (3,300 pounds) into low Earth orbit. While that’s a fraction of the tens of thousands of kilos hauled by the Falcon 9, operated by Elon Musk’s Space Exploration Technologies Corp., it’s enough to transport the satellites now being deployed for everything from super-fast Internet to autonomous driving.

Isar plans its first launch in ’22, HyImpulse in ’23. The target date of Rocket Factory’s first launch was not revealed.

These European companies join dozens such new smallsat rocket companies that already exist. Which will survive the shake-out that always occurs in such new industries only time will tell.

Last two passengers on 1st entirely private manned spaceflight revealed

Capitalism in space: The last two passengers for the first entirely private commercial manned spaceflight, dubbed Inspiration4 and paid for by businessman Jared Isaacman, were announced yesterday, along with a launch date no earlier than September 15, 2021.

Isaacman bought the mission partly to fly in space, but also to raise money for St. Judes Children’s Research Hospital. Both Isaacman and Haley Arceneaux, a former St. Judes cancer patient, will fly. Their two new crew members are both experienced in aviation or spaceflight operations, though neither is a professional astronaut with any training in that field.

[Sian] Proctor describes herself as a scientist turned artist and an “analog astronaut” where people live in environments to simulate long-duration spaceflight. She has done four analog missions including NASA’s Hawai’i Space Exploration Analog and Simulation (HI-SEAS) Habitat to simulate a trip to Mars. She is a pilot, scuba diver, “and loves geoexploring our world.” Born in Guam while her father was working at a NASA tracking station there during the Apollo program, she has a B.S. in environmental science, an M.S. in geology, and a Ph.D. in Curriculum and Instruction: Science Education. She was a finalist in NASA’s 2009 astronaut selection.

While a U.S. Space Camp counselor, [Chris] Sembroski conducted simulated space shuttle missions and supported STEM-based education. He served in the Air Force maintaining a fleet of Minuteman III ICBMs and served in Iraq. After leaving the Air Force in 2007, he earned a B.S. in Professional Aeronautics from Embry-Riddle Aeronautical University. He now works for the aerospace industry in Seattle, although he did not specify what company.

Their spacecraft will be Resilience, the Dragon capsule that flew the first operational manned commercial crew to ISS, and is presently docked to the station. For the Inspiration4 flight however SpaceX is going to install a large domed window at the capsule’s nose, replacing the docking port that will not be needed.

China today used its Long March 4C rocket to successfully place another Earth observation satellite into orbit.

The article at the link also gives a short update on the status of China’s space station, with its first module Tianhe-1 presently scheduled for launch on April 29th, using their biggest rocket, the Long March 5B.

The leaders in the 2021 launch race:

9 SpaceX
7 China
5 Russia
2 Rocket Lab

The U.S. still leads China 13 to 7 in the national rankings.
