Scientists: Liquid surface water might have existed on Mars as recently as 2.3 billion years ago

Map showing locations of salt deposits
Click for full image.

Using orbital data from Mars Reconnaissance Orbiter (MRO), scientists have found salt deposits on Mars where nearby crater counts suggest that the salt water that once held these deposits could have evaporated away as recently as 2.3 billion years ago.

Using [MRO’s] cameras to create digital elevation maps, Leask and Ehlmann found that many of the salts were in depressions – once home to shallow ponds – on gently sloping volcanic plains. The scientists also found winding, dry channels nearby – former streams that once fed surface runoff (from the occasional melting of ice or permafrost) into these ponds. Crater counting and evidence of salts on top of volcanic terrain allowed them to date the deposits.

Past data has suggested that if liquid surface water had existed on Mars, it was gone by three billion years ago.

You can read the scientists’ research paper here.. The maps to the right, figure two from the paper, shows the locations of discovered salt deposits, almost all of which are in the Martian southern cratered highlands of Mars.

Is there uncertainty in these results? My regular readers know that the answer is of course yes. The biggest problem for these Mars researchers is that, despite the surface evidence that liquid water should have once flowed on the surface of Mars, no scientist has yet come up with a satisfactory model of Mars’ past climate that would have made that possible. The planet was either too cold or had too thin an atmosphere, based on other data. And getting it warmer or with a thicker atmosphere involves inventing any number of scenarios that are all questionable, based on what is presently known.

There is also the increasing evidence that glaciers of ice, not water, might have carved those winding, dry channels. If so, many of the assumptions that liquid water existed might simply be wrong, or incomplete. The scientists who wrote this report recognize this importance of ice on Mars, and note in their abstract that

…we think that the water source came from surface runoff, rather than deep groundwater welling up to the surface. The small amounts of water required are most likely from occasional melting of ice.

As always, more data is needed, with the most useful data that will clarify these conclusions being that gathered by future colonists on the surface of Mars itself.

Russia schedules July 23rd for launch of its first unmanned lunar lander in decades

The new colonial movement: The Russia design bureau that is building Luna-25, Russia’s first unmanned lunar lander since the 1970s, has announced that it is targeting July 23, 2022 for launch.

The lunar mission will be launched atop a Soyuz-2.1b carrier rocket with a Fregat booster from the Vostochny spaceport in the Russian Far East. Under the lunar project, the Luna-25 automatic station will be launched for studies in the area of the lunar south pole. The lander is set to touch down in the area of the Boguslawsky crater.

Boguslawsky crater is about 125 miles from the nearest known permanently shadowed craters, and about 250 miles north of the south pole. It is thus not landing in what is presently thought to be the most valuable real estate on the Moon because of the possible presence of water ice, though there might be other resources at Boguslawsky that interest the Russians.

New Arianespace Vega-C rocket being prepared for first launch in April

Engineers in French Guiana are now preparing all the components of the first Vega-C rocket, built by the Italian company Avio, for its first launch in April.

Vega-C is an upgraded version of the Vega rocket and is currently set to launch no earlier than April 2022. The rocket will feature improved first and second stage solid rocket motors, an upgraded liquid-fueled AVUM+ upper stage, and usher in an era of propulsion system commonality between the Vega and Ariane rocket lines.

At the moment they are modifying the Vega launchpad and building a new mission control center. Once completed in March they will stack the rocket.

Vega-C, like its predecessor, is powered by solid rockets, which Avio believes can be competitive with reusable rockets, at least for the next decade or so. Arianespace also hopes to lower costs by using the exact same solid rocket boosters on both Vega-C and its new Ariane 6 rocket. Vega-C’s first stage, using a P120C solid rocket motor, is also used as side boosters on Ariane 6.

China tests space junk removal robot in geosynchronous orbit

China has apparently used a space junk removal robot to tug a defunct Chinese satellite out of geosynchronous orbit, thus opening that slot for future satellites.

Ground tracking by ExoAnalytic Solutions found that the robot, dubbed SJ-21, apparently docked with the defunct satellite on January 22nd. Since then:

In an email to Breaking Defense this afternoon, Flewelling [of ExoAnalytic] said the latest tracking data gathered earlier today from ExoAnalytic’s telescopes show the SJ-21 separating from the Compass G2, leaving the latter in the eccentric “super-graveyard drift orbit.” SJ-21 now has moved back to a near-GEO orbit.

The orbit places the defunct satellite in an orbit above the geosynchronous orbit satellites use, but in an orbit that is not typical.

This work is comparable to what the Japanese/American company Astroscale is presently testing in low Earth orbit, though it appears far more sophisticated. In fact, based on what SJ-21 has done so far, it appears China is far ahead of everyone else in developing in-orbit robotic servicing capabilities.

Astroscale stops orbital capture demo after detecting “anomalous spacecraft conditions”

Capitalism in space: Astroscale has halted an ambitious demonstration in-orbit of its magnetic capture technology when its engineers detected “anomalous spacecraft conditions.”

The demo involved a client satellite (posing as space junk) and a separate robot. Both were equipped with Astroscale’s magnetic capture device. A test in August had successfully separated the two units by a small distance, and then demonstrated that the magnetic capture device could grab the client satellite.

In the on-going but paused demo the robot was to separate, fly a distance away, and then use its autonomous programming to rendezvous with the client and then recapture it again. It successfully separated but that’s when the anomalies were detected. Engineers are now reviewing the data to see if they correct these issues and then proceed with the rest of the demo.

If successful Astroscale would demonstrate that their magnetic capture system works, thus giving them a strong selling point to have satellite companies buy it and install it on their satellites. Then, when the satellite was no longer needed Astroscale could send a robot up, capture it, and then de-orbit it safely.

Oman signs deal with companies to build and launch its first probe beyond Earth orbit

Capitalism in space: The Sultanate of Oman has finalized an agreement to have the Polish company SatRevolution build its first probe to go beyond Earth orbit and have Virgin Orbit launch it.

The target beyond Earth and the missions specific goals has not yet been determined, though the goal is to launch it before the end of ’24.

This agreement is in a addition to an earlier agreement by the same entities to build and launch Oman’s first satellite, set to launch from an airport runway in Cornwall, Great Britain, sometime later this year.

What this agreement tells us that there is money to be made building spacecraft and launching them. Oman wants to have its own space program, like its neighbor the United Arab Emirates (UAE), but like the UAE it does not have the aerospace industry to make that possible. The solution? Hire the skillsets of private companies, in this case from the U.S. and Poland.

Stratolaunch wins Air Force hypersonic research contract

Capitalism in space: Stratolaunch today announced [pdf] that is has been awarded by the Air Force contract to study whether its Roc aircraft carrier and Talon-A research craft will be useful in test hypersonic weapons and spacecraft.

Stratolaunch, LLC is pleased to announce a research contract with the U.S. Air Force Research Laboratory (AFRL).

Stratolaunch, under partnership with Booz Allen Hamilton, is on contract with AFRL to examine and assess the feasibility of hypersonic flight tests of a wide range of Air Force experiments and payloads on a frequent and routine basis.

Stratolaunch supports national security objectives for hypersonic offensive and defensive weapons development through the design, manufacture, and operation of a fleet of reusable hypersonic aerospace vehicles air-launched from its globally deployable carrier aircraft, Roc. The company plans to augment existing Department of Defense flight test resources through affordable, commercially contracted, rapid-turnaround hypersonic flight testing for the Department of Defense and its prime contractor partners.

This contract is not to do actual tests, but to study whether Stratolaunch’s equipment can make hypersonic tests easier, cheaper, and more frequent, as the company promises.

Eta Carinae: The star that proved Hubble was fixed

The Space Telescope Science Institute, which operates both the Hubble Space Telescope and the James Webb Space Telescope, today released a wonderful short video summarizing in images the decades of knowledge that Hubble has gleaned of the massive star Eta Carinae.

I have embedded that video below the fold. What makes Eta Carinae special is that when Hubble was pointed at it shortly after the first repair mission in 1993, that photo proved without a doubt that the telescope’s vision had been fixed. More important, the photo proved that Hubble was going to routinely show us things never before seen. In this case, we got our first sharp and unambiguous view of a massive star exploding.

Isar Aerospace wins $11.3 million in EU innovation competition

Capitalism in space: The German rocket startup company Isar Aerospace has won the first place $11.3 million prize in the European Innovation Council Horizon Prize in the category of low-cost rockets.

Isar was one of three finalists for the prize announced earlier this month by the European Commission, along with another German small launch vehicle developer, Rocket Factory Augsburg, and Spanish company Payload Aerospace, which is working on a reusable small launcher. Those three came from an initial pool or more than 15 applicants, Breton said at a ceremony during the conference to announce the winner.

Isar hopes to launch its rocket, called Spectrum, late this year.

Whether this contest marks the beginning of an open and competitive launch industry in Europe remains unclear. Apparently the EU is thinking of creating what it calls the “European Space Launcher Alliance,” which — from the vague descriptions of it as well as the reservations expressed by Isar officials — might force independent companies to cater their actions to the needs of the larger rocket companies, like Airbus and ArianeGroup. This quote suggests the thinking of those larger companies:

“We understand how important it is for Europe to grab and keep leadership,” said Morena Bernardini, vice president of strategy at ArianeGroup. “This is possible only if industry is pushing in one direction.” [emphasis mine]

If I was a new startup, the highlighted words from this powerful established big space company would worry me enormously. Who decides what that “one direction” is? And what if different companies want to approach rocketry differently?

Lucy update: cause of solar array issue identified

Lucy solar panel graphic

According to the principal scientist for the Lucy asteroid mission, engineers think they have identified what caused one of Lucy’s two fanlike solar arrays to fail to deploy completely.

The +Y array, rather than unfurling a full 360 degrees, instead went 347 degrees. In that configuration, the spacecraft is still generating more than 90% of its expected power. “Power is not an issue for the spacecraft, nor will it be through the entire mission if we have to fly it like it is.”

The arrays unfurl when a motor pulls on a lanyard, swinging one end of the array around and into place. Levison said that the most likely reason the array did not latch is that, for some reason, there was a loss of tension in the lanyard during deployment. That caused it to fall off a spool and wrap around the motor shaft. About 75 centimeters of lanyard remains to be pulled in.

It appears they in April will turn on the array’s motor to try to pull the lanyard in that last little bit. If that doesn’t work, they will then simply leave things as they are, as it appears the array is open enough to give them sufficient power for their mission.

There are risks to that course, however. Because the array is not latched open, it could begin to close, and thus result in less power to the spacecraft. Furthermore, its unlatched state appears to make some planned engine burns too risky.

Mars’ youngest lava flow

Mars' youngest lava flow

Today’s cool image is in some ways another version of my last cool image yesterday. Both are in Mars’s volcano country. Both show what appears to be a lava flow.

Yesterday’s image showed the leftover evidence of a confined flow of lava running in a meandering pattern like a river, and was somewhat distant from the biggest nearby volcanoes. Today’s cool image, to the right and rotated, cropped, and reduced to post here, is instead located smack dab on the inside of what is thought to be Mars’ youngest major lava event, the Athabasca flood lava plain, and in fact is near its outlet, when about 600 million years ago it belched out enough lava in just a matter of a few weeks to cover an area about the size of Great Britain.

The overview map below illustrates this.

Ukrainian rocket company signs deal with Portuguese spaceport organization

Capitalism in space: Ukrainian startup rocket company Promin Aerospace has signed an agreement with the Atlantic Spaceport Consortium (ASC), a Portugal organization that is aimed at building launch facilities on Portuguese-controlled islands in the Atlantic.

Promin has raised $500K for what it claims will be “the smallest solid rocket capable of launching a payload into orbit.” ASC meanwhile is presently building a suborbital launch site in the Azores.

How much of this is real is entirely unknown. The reality of both appear to me to be somewhat nebulous. Nonetheless, if successful the partnership will put another new cheap orbital rocket as well as another spaceport on the map.

Axiom awards construction contract for building Houston space station factory

Capitalism in space: Axiom has awarded its first construction contract for building its space station factory at a Houston industrial park dubbed Spaceport Houston.

Phase I of the Houston Spaceport architecture and engineering design contract was awarded to Jacobs by Axiom Space. This 100,000 sq ft facility will be developed on a 400 acre-site, located within Ellington Airport, at the heart of Space City. Axiom Space, the privately funded space infrastructure developer intends to use this new spaceport to achieve its goal of assembling the first commercial international space station and providing access to low Earth orbit.

The choice by Axiom of Houston for this facility is, at first glance, somewhat puzzling. Once built here Axiom’s large station modules and equipment will then have to be transported to some launch facility, likely Kennedy in Florida. Wouldn’t it have made more sense to build them in Florida, close to where they will be launched?

The explanation lies in politics. Axiom’s management has many close ties to NASA and the Johnson Space Center. Furthermore, Axiom’s first modules will be docked to ISS, run by Johnson. Building in Houston will give Axiom brownie points with these government entities, which will in turn grease the wheels for anything Axiom needs to do at ISS.

Falcon 9 upper stage to impact Moon

A Falcon 9 upper stage launched in February 2015 is apparently now on a course to impact the Moon this coming March.

According to Bill Gray, who writes the widely used Project Pluto software to track near-Earth objects, asteroids, minor planets, and comets, such an impact could come in March.

Earlier this month, Gray put out a call for amateur and professional astronomers to make additional observations of the stage, which appears to be tumbling through space. With this new data, Gray now believes that the Falcon 9’s upper stage will very likely impact the far side of the Moon, near the equator, on March 4.

Grey’s call out for more measurements is because there are uncertainties about this prediction. To prepare for observations of the impact by a variety of lunar orbiters, researchers need better data.

Startup building satellite electric thrusters signs deal with startup building refueling tankers

Capitalism in space: Phase Four, a startup building a new electric xenon thruster for use in satellites has signed an agreement with Orbit Fab, a startup building refueling systems for satellites already in orbit.

Under the agreement announced Jan. 24, the companies will work together to evaluate the refueling potential of traditional electric propulsion propellants like xenon for Phase Four Maxwell engines as well as new propellants like Advanced Spacecraft Energetic Non-Toxic propellant or ASCENT, a monopropellant developed by the Air Force Research Laboratory.

Orbit Fab last year launched its first prototype tanker, successfully testing the refueling port which it wants satellite makers to use so that future tankers can refuel them.

Webb successfully inserted in final orbital position at the Sun-Earth Lagrange point

The James Webb Space Telescope today successfully completed a five minute firing of its engines to place it at the Sun-Earth Lagrange point dubbed L2.

Webb’s orbit will allow it a wide view of the cosmos at any given moment, as well as the opportunity for its telescope optics and scientific instruments to get cold enough to function and perform optimal science. Webb has used as little propellant as possible for course corrections while it travels out to the realm of L2, to leave as much remaining propellant as possible for Webb’s ordinary operations over its lifetime: station-keeping (small adjustments to keep Webb in its desired orbit) and momentum unloading (to counteract the effects of solar radiation pressure on the huge sunshield).

Engineers will spend the next three months aligning the segments of Webb’s large primary and secondary mirrors, while they wait for the telescope to cool down to the ambient very cold temperatures required for it to detect the tiny infrared heat emissions from very faint very very very distant objects.

U-shaped meandering Martian ridge

Broad U-Shaped meandering ridge on Mars

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on December 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label a “Broad U-Shaped Ridge”. The two black squares are merely areas where no data was gathered.

Is this a fossilized river, of which scientists have identified more than 10,000 in the Arabia Terra transition region between the northern lowland plains and the southern cratered highlands? Arabia Terra however is literally on the other side of Mars, very far away.

The location, as shown in the overview map below, instead suggests that, if this U-shaped meander is a fossilized river, it isn’t one created by water or ice.

Another study says Mars does not have liquid water under its south pole

The uncertainty of science: A new study now claims that the presumed detection of lakes of liquid water under the Martian southern polar ice cap in 2018 was likely wrong, and that the detection was more likely volcanic rock.

The researchers think their conclusion — volcanic rock buried under ice — is a more plausible explanation for the 2018 discovery, which was already in question after scientists calculated the unlikely conditions needed to keep water in a liquid state at Mars’ cold, arid south pole.

“For water to be sustained this close to the surface, you need both a very salty environment and a strong, locally generated heat source, but that doesn’t match what we know of this region,” says the study’s lead author, Cyril Grima, a planetary scientist at The University of Texas at Austin Jackson School of Geosciences.

So my readers know how uncertain all of this is, note that the 2018 discovery of underwater liquid water was later confirmed by other scientists in 2020, then rejected by different researchers in 2021, who claimed it was clay instead.

In other words, the scientists have some inconclusive data that could mean many different things, either water, clay, volcanic rock, or maybe something else that someone hasn’t yet suggested. To really answer the question will require far more data, with some like required in situ on Mars itself.

Pseudo-private rocket company in China raises $200 million from Chinese investors

The Chinese pseudo-private rocket company Galactic Energy has successfully raised $200 million from a number of Chinese investors, money that the company will use to develop a mid-size rocket with a reusable first stage.

Though the company is not directly funded by the Chinese government, it is not an independent private company, which is why I label it “pseudo.” Everything it does is closely supervised and approved by the communist government. Also, some of this investment money apparently came from “state-backed investment vehicles,” which in plain language are fronts used by the government to funnel funding to these companies while maintaining the false appearance the companies are entirely private.

The fake nature of this charade has apparently influenced the decisions of real investors:

Incomplete information on funding in China’s emerging commercial space sector suggested that overall investment was lagging just over halfway through 2021, concentrating in fewer players.

It appears that no one outside China is willing to put money behind these companies, and even within China there is hesitancy.

Nonetheless, by letting many such competing operations that can also make profits for investors, China is successfully encouraging some innovation. That Galactic Energy — as well as several others — are planning on building reusable rockets is evidence of that.

Astra completes 1st static fire dress rehearsal countdown of Rocket-3 at Kennedy

Capitalism in space: On January 22, 2022, Astra successfully completed at Cape Canaveral the first static fire dress rehearsal countdown of its Rocket-3 rocket.

“Successful static test completed. We will announce launch date and time when we receive our license from the FAA,” said Chris Kemp, founder and CEO of the Alamada, California-based company on Twitter. The company, which was formed in 2016, had been targeting this month for the launch.

The FAA apparently required this successful dress rehearsal before it would provide the launch license. Expect the launch to follow almost immediately after the permit is issued. If successful it will be Astra’s second orbital launch, and the first to carry actual satellites for customers, three cubesats from three different universities and one from NASA’S Johnson Space Center.

Confirmed: All debris cleared from Perseverance sample tube

Mosaic showing the clearing of debris
Click here and here for original images.

The Perseverance science team today announced in an update that their effort to clear the sample tube of bits of core sample has succeeded, as indicated partly by the two images above that I posted on January 19th.

According to the report, the two small pieces visible bottom center fell out after two small rotations of the carousal. Other pieces however remained, and these were removed as followed:

On Monday, Jan. 17, the team commanded another operation of the rotary percussive drill in an attempt to dislodge more material from the tube. With the tube’s open end still pointed towards the surface, we essentially shook the heck out of it for 208 seconds – by means of the percussive function on the drill. Mastcam-Z imagery taken after the event shows that multiple pieces of sample were dumped onto the surface. Is Tube 261 clear of rock sample? We have new Mastcam-Z images looking down the drill bit into the sample container that indicate little if any debris from the cored-rock sample remains. The sample tube has been cleared for reuse by the project.

The team is now discussing their next step, which could be drilling a new hole at this spot or moving on.

NASA: No further Artemis Moon landings for at least two years after first in 2025

The tortoise appears to be dying: NASA today announced that there will be a two-plus year pause of Artemis missions to the lunar surface after it completes its hoped-for first manned Moon landing in 2025.

In presentations at a two-day meeting of the NASA Advisory Council’s Human Exploration and Operations Committee Jan. 18 and 19, agency officials said the Artemis 4 mission, the first after the Artemis 3 mission lands astronauts on the moon, will not attempt a landing itself.

Instead, Artemis 4 will be devoted to assembly of the lunar Gateway. The mission will deliver the I-Hab habitat module, developed by the European Space Agency and the Japanese space agency JAXA, to the Gateway. It will be docked with the first Gateway elements, the Power and Propulsion Element and Habitation and Logistics Outpost, which will launch together on a Falcon Heavy in late 2024 and spend a year spiraling out to the near-rectilinear halo orbit around the moon.

Essentially, the Biden administration appears to be switching back to NASA’s original plans, to require use of the Lunar Gateway station for any future lunar exploration, thus delaying that exploration considerably. Do not expect any of this schedule to take place as promised. The 2025 lunar landing will be delayed, as will all subsequent SLS launches for Artemis. The rocket is simply too complicated and cumbersome to even maintain one launch per year, while inserting Gateway into the mix only slows down lunar exploration even more.

NASA officials also revealed that they are limiting their lunar landing Starship contract with SpaceX to only that single planned ’25 Moon mission. For future manned missions to the Moon the agency will request new bids from the entire industry.

NASA’s Human Landing System (HLS) Option A award to SpaceX last year covers only development of a lander and a single crewed flight on Artemis 3. NASA will acquire future landings through a separate effort, called Lunar Exploration Transportation Services (LETS). The goal of LETS is to select one, and possibly more, companies to provide “sustainable” landing services.

The timing of LETS — a draft request for proposals is scheduled for release this spring — means there will be a gap of a couple years before the first landing service acquired through that program would be ready. “It’ll be about two years from the Option A award to the LETS award before we’ll have this sustainable lander,” Kirasich said. “It’s a different lander with more aggressive requirements than Option A.”

It appears that Jeff Bezos’ political lobbying efforts have paid off, and that NASA is now reopening bidding so that his consortium, led by Blue Origin, can once again compete for that lunar lander contract. Whether the Bezos’ team will be able to propose anything comparable to Starship is however very questionable.

None of this really hurts SpaceX. Its contract with NASA helps them develop a Starship lunar lander. Then, while NASA twiddles its thumbs building Gateway, it will be free to fly its own lunar missions, selling tickets on the open market. I suspect that — should NASA succeed in landing humans in ’25 — the next American manned landing on the Moon will be a bunch of SpaceX customers, not that second Artemis mission sometime in the late 2020s.

SpaceX of course will also be able to bid on that second lunar landing competition. And it will be hard for NASA not to award Starship a further contract, even if others are competing against it. Starship will be operational. The others will merely be proposed.

Latvian/Bulgarian commercial partnership to launch cubesats to monitor space weather

Capitalism in space: Mission Space, a Latvian company, plans to build a constellation of 24 cubesats designed to monitor space weather and solar activity, using cubesats manufactured by the Bulgarian company EnduroSat.

Mission Space plans to make its software model of the near-Earth radiation environment available in mid-2022, before launching its Aurora-1 detectors with EnduroSat in the fourth quarter of the year.

Mission Space was founded in 2020 to offer space weather monitoring as a service. With data supplied by its constellation, Mission Space will provide data and analytics to government agencies in addition to establishing a cloud-based platform to help commercial satellite operators prepare for solar storms, assess risks and monitor radiation levels.

EndoroSat already has five satellites in orbit, with ten more planned for launch in the next two years.

I think that both these companies demonstrate that a modern satellite business truly can be started in someone’s garage. Because cubesats are so small and are also somewhat standardized, you don’t need a large facility to build them.

SpaceX’s Starship gets Air Force point-to-point cargo study contract

Capitalism in space: The Air Force Research Laboratory (AFRL) has signed a $102 million five year contract with SpaceX to study the practicality of using its Starship spacecraft as a method for transporting large cargo point-to-point on Earth.

[Program manager Greg] Spanjers said the SpaceX work is focused in four areas: collecting data from commercial orbital launches and landings; exploring cargo bay designs compatible with U.S. Transportation Command containers [TRANSCOM] and support rapid loading and unloading; researching landing systems that can operate on a variety of terrain; and demonstrating the heavy cargo launch and landing process.

The emphasis on landing options and interoperability with TRANSCOM containers and loading processes is an important element of the project, Spanjers noted, because the department’s vision for how the point-to-point capability could be used is broader than just the commercial business case. While companies are primarily interested in delivering cargo to and from established sites, the military wants to deliver supplies and humanitarian aid to locations that may not have spaceports.

This contract is in many ways similar to NASA’s manned Starship lunar lander contract. Both provide SpaceX some cash for developing a different version of Starship, even as the bulk of development money for building Starship comes from the private investment community.

NRO to buy radar data from private companies

Capitalism in space: The National Reconnaissance Office (NRO) has signed contracts with five commercial companies to purchase the Earth radar data that they produce to see if that data will be useful for future reconnaissance and surveillance.

The National Reconnaissance Office announced Jan. 20 it has signed agreements with commercial radar imagery providers Airbus U.S., Capella Space, Iceye U.S., PredaSAR and Umbra.

These agreements are study contracts that give the NRO access to the data collected by these companies’ synthetic aperture radar (SAR) satellites, and are intended to help the agency better understand the quality of commercially available imagery. “We know that users across the national system for geospatial intelligence are eager to explore commercial radar, and these contracts will allow us to rapidly validate capabilities and the benefits to the national mission,” NRO Director Chris Scolese said in a statement.

Essentially, NRO is looking to see if it can fill some of its radar data needs from inexpensive privately built satellites, rather than build and launch its own very costly radar satellites. The agency is already doing the same with commercial optical data.

Debris from Russian anti-sat test just misses Chinese satellite

A Chinese satellite was almost destroyed on January 18th when a piece of debris from Russia’s November 15th anti-satellite test zipped past at a distance of less than a few hundred yards.

Expect more such events in the coming years.

This quote from the article I found somewhat ironic:

In an article from Beijing tabloid Global Times Jan. 20, cited experts stated that further close encounters cannot be ruled out. “Currently, they keep a safe distance but the chance for these two getting close in the future cannot be excluded,” said space debris expert Liu Jing.

Aerospace commentator Huang Zhicheng, told the publication that the growing issue of space debris should be addressed, including through international legal mechanisms. “It is not only necessary to conduct research on experimental devices or spacecraft to remove space debris, but also to formulate corresponding international laws and regulations on the generation of space debris under the framework of the UN,” Huang said. [emphasis mine]

Since anything published in the Chinese press must be approved by the Chinese government, this statement is essentially what the Chinese government wants said. For China however to demand other nations obey international law and not create more space junk that threatens others is hilarious, considering that China this year will likely launch two rockets whose core stages will crash to Earth uncontrolled, in direct violation of the Outer Space Treaty that China is a signatory to.

Since China doesn’t obey the treaties it signs, why should it expect others to do the same?

Contact restored with InSight after dust storm

The InSight science team has regained communications with the lander on Mars following a dust storm that caused it to shut down all operations entirely.

Though the tweet from the science team says the space craft is out of safe mode, that really doesn’t appear to be the case. Safe mode is a condition where a robot ceases all science operations, hunkers down, and awaits further orders. All that has happened here is that the engineers have regained contact after communications were lost on January 7th. No science is being done.

The resumption of communications is excellent news, however. They must now access how much power the lander’s solar panels are generating to see if they can turn InSight’s main instrument, its seismometer, back on. Those panels might be badly covered with dust, preventing operations.

Axiom & UK entertainment company propose film studio in space

Film studio balloon

Capitalism in space: Axiom has signed a deal with British-based entertainment company, Space Entertainment Enterprise (SEE) to add an inflatable film studio module to its private commercial space station.

Axiom Space’s modules are to be added to the ISS throughout the second half of the 2020s. SEE-1 would be added along with these components.

Once the ISS program is near its end, the plan is for the commercial segment to be detached to form an independent station.

According to SEE, the spherical studio module is planned to be about 20 feet (6 meters) in diameter once fully expanded in space. Its interior is expected to provide an “unobstructed pressurized volume” that can be adapted for a range of media activities, including film production, music, sports and livestreaming events.

The graphics that accompanied the press release of the British company make me very skeptical of it. Posted on the right, it shows this inflatable module as a simple sphere, like a balloon. No manned module ever built, including the inflatable modules launched by Bigelow, has ever looked anything like this. This suggests a certain level of ignorance from the entertainment company which also suggests this project really doesn’t yet exist. The press release and agreement with Axiom seems instead merely an effort to drum up investment capital from investors who know even less.
