First air leak crack on ISS has not grown

9:25 am

A inspection of the first air leak crack that had been found and patched in the Zvezda module on ISS last year has found that it apparently not increased in size since then.

The size of a crack in the intermediate chamber of the Russian Zvezda module aboard the International Space Station (ISS) remains unchanged, cosmonaut Sergei Ryzhikov reported to Russia’s Flight Control Center on Wednesday. “It [the length] has not changed. As in the previous measurements, I do not see any changes,” Ryzhikov said during his talks with Mission Control broadcast on NASA’s website.

On February 23, the cosmonaut carried out work with a microscope to trace another possible air leak. The photos of the work were transmitted to Earth and the video from GoPro cameras will be sent via the Russian broadband communications system. After completing the work, the cosmonaut reinstalled the patch in the area of the crack.

This Russian report is decidedly unclear about some details. Though it appears the astronaut was using the microscope to inspect another leak, he also apparently removed the patch on the first leak to check the crack for any changes, then replaced it. How one removes and replaces such a patch is a puzzle however. Such things are generally not removable.

No matter. The important detail is that the crack has not grown. If it was a stress fracture the recent dockings of spacecraft to the nearby port might cause it to grow. That it has not is good news.

The bad news is that the inspection did not find the second small leak that is thought to be in this same Zvezda module.

Starship #10 completes launch dress rehearsal & static fire test

9:18 pm

Starship #10 at static fire test
Screen capture from LabPadre live stream.

Capitalism in space: Starship #10 today successfully completed a launch dress rehearsal and static fire test in preparation for a planned 30 to 40 thousand foot test flight, possibly as soon as February 25th.

The Starship SN10 (“Serial No. 10”) vehicle performed its first “static fire” test on Tuesday (Feb. 23), lighting up its three Raptor engines for a few seconds at 6:03 p.m. EST (2303 GMT) at SpaceX’s South Texas site, near the Gulf Coast settlement of Boca Chica Village.

Static fires, in which engines briefly ignite while a rocket stays anchored to the ground, are a common preflight checkout for SpaceX. If all went well with today’s test, SN10 remains on track to launch soon — perhaps as early as Thursday (Feb. 25) — on a 6-mile-high (10 kilometers) demonstration flight into the South Texas skies.

I personally think it would be quite ironic if this Starship flies on the same day the second SLS static fire test had been originally scheduled but postponed. The contrast between the two development programs continues to be stark and astonishing. While one program has been flying test articles repeatedly as well as doing numerous engine and tank tests, the other has had trouble getting one static fire test completed without a hitch.

UPDATE: Apparently they have decided to swap out one Raptor engine based on the results of the static fire test, and thus will not do a flight tomorrow.

Martian pits or dark splotches?

11:37 am

Martian pits or dark splotches?
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on January 2, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a windswept sandy region of ridges and dunes with two dark features nestled between ridges.

What are these dark patches? At the available resolution they appear to be deep pits, with the one on the right having a significant overhang. And if these are pits, they would appear significantly different than most of the previously identified Martian pits, which are usually somewhat circular in shape. These features have very complex shapes, as if the pit is conforming itself to the terrain that surrounds it.

The resolution, however, is not good enough to confirm this interpretation. These dark patches could also be exposed volcanic material, darker than the surrounding terrain. The location, as shown in the overview map below, adds weight to this interpretation.

SpaceX delays all launches while it investigates failed booster landing

9:22 am

Capitalism in space: In order to investigate the failure of the first stage to land successfully during the last Starlink satellite launch on February 15th, SpaceX has paused all further launches, with an expected delay overall of one to two weeks before launches resume.

Analysis by Scott Manley suggests during the re-entry burn (as the 1st stage re-entered the atmosphere) one of the engines had issues, causing the booster to break-up shortly before it hit the ocean.

When SpaceX was first attempting to land its first stages, the boosters would routinely crash, and the company would not slow its launch schedule because the boosters had still functioned as expected during launch. Nor was anyone disturbed by those failures nor did anyone expect SpaceX to pause further launches.

Things are different now. We have a high expectation that a Falcon 9 engine will relight and work every time, all the way back to its landing pad. Any failure later in the flight, even if the rocket got the payload into orbit, raises questions that must be answered. Hence the delay in further launches.

Overall, this higher expectation of success is a good thing. It says that we now expect rockets to be able to land successfully. And getting this problem fixed will only increase the chances that they will do so more reliably in the future.

Firefly gets another launch contract

9:10 am

Capitalism in space: Firefly Aerospace, which hopes to do the first launch of its new Alpha rocket sometime this spring, has won another launch contract, this time with General Atomics to put an Earth science satellite in orbit in ’22.

The other contracts:

In December, the company won a NASA Venture Class Launch Services launch contract valued at $9.8 million to launch two sets of cubesats into polar orbits. It won a $93.3 million contract from NASA’s Commercial Lunar Payload Services program Feb. 4 for the 2023 launch of the company’s Blue Ghost lander carrying NASA payloads. That lander will be launched on another company’s rocket rather than Alpha.

Like all new rockets, the first launch will be highly risky. If successful however it will add one more launch company to the smallsat market, and encourage a further drop in the cost of getting such smallsats into orbit.

Second passenger chosen for private manned SpaceX mission

11:37 pm

Capitalism in space: Jared Isaacman, who has purchased an entire Dragon/Falcon 9 flight for the first private commercial manned mission scheduled for later this year, has picked the flight’s second passenger.

The second member of a four-person crew for what’s likely to be the first privately funded orbital space tour has been identified: She’s Hayley Arceneaux, a 29-year-old physician assistant who works at St. Jude Children’s Research Hospital in Memphis, Tenn. — and was successfully treated for bone cancer at St. Jude almost two decades ago.

Arceneaux was invited to be part of the Inspiration4 mission weeks ago by its commander and principal funder, Shift4 Payments CEO and founder Jared Isaacman — but her identity was kept secret until today.

This choice fits Isaacman’s main goal, which is to use the publicity of the flight in raise money for St. Jude’s. So far almost $10 million has been raised.

Two more passengers need to be chosen. One will be picked from a lottery of people who donate to St. Jude’s, with the second being an entrepreneur picked by a panel of judges. The deadline to enter both slots closes on February 28th.

As for the flight itself, it will spend two to four days in orbit.

First panorama from Perseverance

11:02 pm

The Perseverance science team has released the first panorama taken by the Perseverance rover after landing on Mars February 18th.

Below the fold however I have embedded something far better than the science team’s mosaic. Andrew Bodrev has taken these same navigation camera images and created a 360 degree virtual reality panorama, one that you can pan and tilt at your own pleasure. The view also includes the sounds of the Martian winds from the rover’s microphone. If you pause it you won’t hear the sounds, but you can scan and rotate for as long as you want.

NASA postpones second SLS static fire test

10:52 pm

NASA today announced that it was postponing the second SLS static fire test of the rocket’s core stage due to a valve issue in its main engines.

NASA said it was postponing the Green Run static-fire test, which had been scheduled for Feb. 25, after discovering a problem with one of eight valves called “prevalves” associated with the stage’s four RS-25 main engines. The valve, which supplies liquid oxygen, was “not working properly,” NASA said in a statement, but didn’t elaborate on the problem.

Engineers identified the problem during preparations over the weekend for the test. NASA said it will work with Boeing, the prime contractor for the core stage, to “identify a path forward in the days ahead and reschedule the hot fire test” but did not set a new date for the test.

This was not the first time Boeing and NASA has had valve problems with the rocket, though this problem appears unrelated to the previous issue.

Either way, the continuing technical problems — such as the two previous aborts during testing — does not build confidence in the rocket. First, the schedule is very tight, and is getting tighter. Its first unmanned test flight was supposed to happen by the end of this year, and right now that looks very unlikely. Yet, it must happen within the next twelve months because they have begun stacking the strap-on solid rocket boosters, and those have a sell-by date.

More important, these issues raise big red flags as to the overall trustworthiness of the rocket. I certainly would not want to fly on it, at least not until I see it fly at least a half dozen times successfully. The problems however suggest that achieving such a track record is going to be quite difficult.

And if SLS has any major failures during any launch, be prepared for Congress’s support to finally collapse, especially with the on-going spectacular progress being achieved by SpaceX with Starship along with two Falcon Heavy launches planned for this year.

Movie of Perseverance’s descent and landing

1:07 pm

Cool movie time! The science team for Perseverance today released movie footage obtained by the rover as it descended and landed on Mars in Jezero Crater. That video is embedded below.

If you compare what this movie sees with the orbital images from Mars Reconnaissance Orbiter (MRO) that I posted earlier today, you can recognize the features in the crater and anticipate exactly where the rover is going to land.

New 3D atlas of all binary stars within 3,000 light years of Sun

9:45 am

Using data from Europe’s Gaia satellite, astronomers have now compiled a 3D map of every binary star within 3,000 light years of the the Sun — 1.3 million — including many widely spaced binaries that were previously not identified.

The one-of-a-kind atlas, created by Kareem El-Badry, an astrophysics Ph.D. student from the University of California, Berkeley, should be a boon for those who study binary stars — which make up at least half of all sunlike stars — and white dwarfs, exoplanets and stellar evolution, in general. Before Gaia, the last compilation of nearby binary stars, assembled using data from the now-defunct Hipparcos satellite, included about 200 likely pairs. “This is just a massive increase in sample size,” said El-Badry. “And it is an increase in what kinds of evolutionary phases we find the binaries in. In our sample, we have 17,000 white dwarfs alone. This is a much bigger census.”

The data has also shown that the bulk of these binaries are made up of twins, stars similar in mass, something that is surprising and as yet unexplained, especially for binaries where the stars are widely separated.

All systems on Perseverance so far check out good

9:30 am

The Perseverance science team reported this past weekend that all systems on the rover have so far reported back and are operating as expected, including the test helicopter Ingenuity.

Some more images were sent back, all visible at the Perseverance raw image website. The most spectacular new image of Perseverance released however was one taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and posted below.

Update on Starship: Flight of prototype #10 possible this week

8:53 am

Link here. Lots of stuff going on, with Starship prototypes 15 through 19 being assembled and waiting n the wings. Crews have also repaved and expanded the landing pad at Boca Chica, and begun assembling the first Super Heavy prototype.

The most significant tidbit to me was this:

One section inside a production tent appears to be undergoing preparations to cover the entire windward side in [thermal patches].

This unnamed section could indicate a vehicle that will be taken to an altitude that would test its heat shield under re-entry conditions. Current [thermal] patches are mostly being tested to see how they perform during the stresses of cryogenic propellant loading and launch and landing vibrations.

It is not known yet to which prototype this section belongs to, but that it is being prepared means that SpaceX is moving relentless towards that first orbital flight.

Ham picks up signal from China’s Tianwen-1 Mars orbiter

5:58 pm

An amateur ham radio operator announced on February 10th that he has been able to pick up a radio transmission from China’s Tianwen-1 Mars orbiter.

As reported on Spaceweather.com, Canadian radio amateur Scott Tilley, VE7TIL, has snagged another signal from deep space. His latest conquest has been to copy the signal from China’s Tianwen-1 (pronounced “tee-EN-ven”) probe, which went into orbit around Mars on February 10. Tilley told Spaceweather.com that the probe’s X-band signal was “loud and audible.”

“It was a treasure hunt,” Tilley told Spaceweather.com. He explained that while the spacecraft did post its frequency with the International Telecommunication Union (ITU), it was too vague for precise tuning (X band is between 8 GHz and 12 GHz).

What makes this detection especially interesting is that it indicates the possibility that in the somewhat near future some ham might actually be able to win the Elser-Mathes Cup. According to this article [pdf] from the national ham radio magazine QST, by the late 1920s there was a desire to create a new challenge for hams, as by then they had managed to devise methods for communicating across the entire globe.

Amid this disillusionment, [Colonel Fred Johnson Elser] visited ARRL [the national ham radio organization] and had the pleasure of meeting League co-founder and first president Hiram Percy Maxim, whose many interests included Mars. Elser reported that Maxim even owned a globe of the planet, with all of its known features demarcated.

Elser returned to his home in Manila and befriended Stanley Mathes, a Lieutenant Commander in the Navy who had been stationed in the Philippines. Based on their shared belief that Amateur Radio technology would improve at a prodigious rate, Elser and Mathes devised an award for the most ambitious Amateur Radio contact they could imagine. In honor of Hiram Percy Maxim’s love of the Red Planet, Elser and Mathes established the Elser-Mathes Cup, to be awarded for the “First Amateur Radio Two-Way Communication Earth & Mars.”

That cup has remained unclaimed since it was established in 1929, more than ninety years. The detection by Tilley above using ham equipment suggests that a winner might soon be able to lay claim to the cup. However,

Fred Elser and Stanley Mathes stipulated that the contact must be two-way, and that the transmission on the Mars end of the contact cannot be generated by a “robot.” Until we can put a ham on Mars, the Elser-Mathes Cup will go unclaimed.

As almost all astronauts are also hams, all that must happen is for an astronaut to get to Mars, land, and communicate back to Earth using ham equipment. While this will not happen soon, the possibility it will happen in the not-too-distant future is finally becoming a reality. Stay tuned.

Hat tip to ham Don Huddler N4RRT.

Roscosmos head: Russia to launch 29 rockets in ’21

5:10 pm

Dmitry Rogozin, the head of Russia’s space agency Roscosmos, announced yesterday that they expect to complete 29 launches in 2021.

These numbers include all Russia’s launches, including the ones done for Arianespace in French Guiana. In my regular launch updates I don’t count those as Russian launches, as they are run and controlled by Arianespace, under Arianespace contracts.

Nonetheless, there should be an increase in the number of Russian launches in ’21, as they should resume OneWeb launches that were halted last year due to that company going into bankruptcy and then recovering. That bankruptcy meant that Russia’s total launches last year were less than half what they predicted.

The increase in ’21 does not mean Russia will successfully complete 29 launches. Rogozin and Roscosmos have for years routinely overstated their goals, and I think they are doing so again. I expect Russia to complete around 20-25 launches by the end of the year. If they top 25 it would make ’21 their best year since ’15.

Partly ice-filled Martian crater?

Partly ice-filled Martian crater?
Click for full image.

Time for another cool Martian image. The photo to the right, rotated, cropped, and reduced to post here, was taken on January 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The section I have focused on is a single crater about a mile and a half wide.

What makes this crater interesting is the material that appears piled up against the crater’s northern half. Furthermore, both the floor of the crater as well as this piled up material looks like it is eroding away, kind of like a block of ice which is having warm water sprayed on it.

So, is this glacial ice?

Bloomberg editorial: Scrap SLS!

8:38 am

I wonder who has said this before? In a scathing Bloomberg editorial yesterday, the news service called for President Biden to scrap the Space Launch System (SLS) and let private enterprise do the job instead.

The editorial’s opening sentence will sound very familiar to regular readers at this website:

Why is the U.S. government building a space rocket? In particular, why is it building a space rocket that has cost nearly $20 billion and counting, is years behind schedule, relies on outdated technology, suffers by comparison to private-sector alternatives, and has little justification to begin with?

That a major leftwing news source is beginning to endorse private enterprise and lambast SLS is a further sign that the political winds are blowing hard against this giant wasteful boondoggle. Should anything at all go wrong in its upcoming test schedule expect to see more such calls, coming from even more unlikely and unexpected places.

The lumbering thick-headed Washington political community is beginning to finally move towards the right conclusion, only a decade late.

Perseverance has successfully landed

2:07 pm

Cheers in the control room

First image from Perseverance on the ground

The rover Perseverance has successfully landed in Jezero Crater on Mars.

The picture to the right is a screen capture of everyone cheering in the control room on hearing the good news.

The second image is the first image beamed back, from the rover’s hazard camera used mostly for guiding it in future travels. The haze is from the dust kicked up during landing.

The engineering narrator indicated that they also know exactly where the rover landed, and it is a good location, but NASA’s live stream appears uninterested in telling us this critical information. Right now they are spending time blathering on with more NASA propaganda.

I should get this information during the post-landing press conference, which begins at 5:30 (Eastern).

UPDATE: The press conference started 30 minutes late, and then spent the first 25 minutes letting the top NASA managers claim credit for everything. Then we finally got to hear from actual mission managers to tell us where the rover landed and what should happen next.

Eroded mound in Mars’ glacier country

Eroded mound in Mars' glacier country
Click for full image.

Cool image time! The image to the right, reduced to post here, was a captioned release today by the science team of the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is located in Deuteronilus Mensae, a region of chaos terrain in the transition zone between the northern lowland plains and the southern cratered highlands that is also part of a 2,000 mile-long band that I call Mars’ glacier country. From the caption, written by Dan Berman, senior scientist at the Planetary Science Institute in Arizona:

Lobate debris aprons are commonly found surrounding dissected plateaus in the Deuteronilus Mensae region of Mars. They have been interpreted as debris-covered glaciers and radar data have shown their interiors to be composed of pure ice.

The mound in this image is slightly removed from most of the other plateaus, and the [debris apron] surrounding it is highly degraded. The sharp scarps on the western and eastern sides of the mound indicate that a great deal of the ice once found in these landforms has since sublimated away, leaving behind these collapsed debris cliffs.

I wonder if further research might find an ice layer in those cliff walls, especially because this photo strongly suggests that much of this mound is made of ice that is sublimating away or has flowed downward to form the debris aprons as well as that central gully.

The overview map below shows its location in Deuteronilus Mensae as well as showing almost all of the entire band of Mars’ glacier country.

Perseverance’s possible travel route on Mars

9:06 am

Perseverance's planned driving routes
Click for full image.

In touting the plans of NASA and the European Space Agency (ESA) to someday launch a rover to Jezero Crater designed to pick up the cached samples that Perseverance is going to leave behind, NASA today published the map to the right, showing Perseverance’s planned driving routes in the crater, on the large delta that poured into the crater in the past, and beyond that crater.

The yellow lines indicate Perseverance’s planned route, beginning somewhere in that red landing ellipse. The green lines indicated the many proposed landing sites and pathways the proposed follow-on sample retrieval mission can take to grab Perseverance samples.

The planned route looks like they will spend a lot of time exploring the top of delta, then will move out of the crater and to the southwest towards what had been another candidate landing site for Perseverance, now dubbed the Midway ellipse.

What route the science team will eventually take at the delta depends greatly on exactly where Perseverance lands today. We will know more in only a few hours.

Texas power outages delay Starliner but not Starship

8:42 am

Boeing announced yesterday that due to the winter storms and power outages in Texas it has delayed the second unmanned demo flight of its Starliner manned capsule from March 25 to no earlier than April 2nd.

Meanwhile, SpaceX’s Starship operation in Boca Chica, Texas has been proceeding practically unaffected by the power outages.

At the southernmost fringes of Texas, SpaceX’s Boca Chica Starship factory hasn’t been insulated from the chaos, though a large Tesla Solar and Energy installation has almost certainly lessened the blow. Highly cognizant of Boca Chica’s shortcomings for industrial-grade power needs, SpaceX installed that solar array and Tesla-made Powerpacks almost three years ago and substantially expanded it in 2020.

As a result, despite major issues posed by freezing weather and power grid instability, SpaceX has managed to keep the lights on and continue work at its Starship factory, while also slowly but surely preparing Starship serial number 10 (SN10) for its first static fire and high-altitude launch.

The weather is clearly slowing the Starship test schedule, but at least the work seems insulated from loss of power.

Hungarian company awarded NASA contract to develop Moon mini-rover

4:49 pm

A Hungarian company has won a NASA contract worth $225K to develop what the company calls its Puli Moon mini-rover.

Named after a Hungarian breed of dog, the Puli rover is a low-cost platform designed to carry different payloads, including the ice water snooper, which won the 2020 “Honey, I Shrunk the NASA Payload” challenge, a competition organised by the U.S. space agency. Weighing less than 400 grammes (14 oz), its purpose is to probe for water ice by identifying and mapping the subsurface hydrogen content of the lunar soil.

The “news article” at the link appears to be a poorly researched article distributed by Reuters that has now been reprinted without changes by such stalwart American mainstream news outlets like the New York Post and MSN.com, to name two. Neither bothered to do any further research.

The article falsely claims that the airplane-based SOFIA telescope recently confirmed there is water on the Moon. It also claims that this rover will be on a lunar mission next year, something that does not seem likely at all.

A look at the company’s website clarifies things. The company competed in a NASA contest offering its design of a very tiny lightweight rover, won, and was then awarded a larger development contract of $225K. No launch is presently set, though if the company is successful in building it for this cost, they will likely get a berth on a later unmanned mission.

Russia denies visa to NASA manager in retaliation for claimed similar denial by U.S.

3:29 pm

Russian officials revealed today that they denied and entrance visa to a NASA manager in retaliation for what they claim was a similar denial by U.S. government of another Russian individual.

The Russians did not reveal the names of either official, or even the work they were involved in. It appears however that that Russian blocked from entering the U.S. was not involved in space work. We also do not know if this was done during the Trump or Biden administration.

Cool image time. The photo to the right, rotated, cropped, and reduced to post here, was taken on October 26, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and labeled by the science team as simply an “Enigmatic Channel in Syrtis Major.”

It shows a channel going downhill to the northeast east in a series of steps, separated cliffs that in the southwest hikers call pour-offs, with the channel becoming initially deeper and then slowly becoming more shallow, until the next pour-off. On Earth the pour-offs would be waterfalls, with a deep pond at the base. On Mars?

Without doubt this channel poses mysteries, but maybe with a little research we can make it less enigmatic. Asl always, the overview map below gives context, and helps give a possible explanation for what created this channel.

SpaceX raises another $850 million in investment capital

8:10 am

Capitalism in space: SpaceX last week successfully raised another $850 million in investment capital in order to fund both its Starlink and Starship projects.

The article does not detail how the company plans to use the money, though it does also indicate this was not all that was raised.

In addition to SpaceX further building a war chest for its ambitious plans, company insiders and existing investors were able to sell an additional $750 million in a secondary transaction, one of the people said.

If I understand this correctly (which I admit I might not), this means SpaceX now has an additional $1.6 billion on hand in addition to the $2 billion it has previously raised.

Even if it only raised $850 million, that gives it a war chest of almost three billion for both Starlink and Starship. With Starlink already bringing in some earnings, the company should have enough to get done what it aims to do.

Strange corroding features on Mars

Strange corroding features on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and enhanced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on October 4, 2020. It shows what appears to be features that are either corroding or eroding away, with the lower areas filled with rippling sand dunes.

The circular features might be ancient craters. The material that partly fills them might be a layer of dust or sand that the wind is slowly blowing away to dig out the depressions along the southern cliff wall.

According to the MRO science team’s interpretation of the colors produced by the high resolution camera [pdf], the dark blue colors here are likely “coarser-grained materials (sand and rocks)”, while the orange-red material on the higher terrain is likely dust.

Could this material be evidence of buried ice eroding away? At first I thought so, and then I took a look at the photo’s location, as shown in the overview image below.

Momentus signs deal to deliver two private cubesats to lunar orbit

11:55 am

Capitalism in space: Momentus has signed a deal with a Singapore startup to provide the transportation to lunar orbit of two cubesats using its next generation space tug.

Momentus Inc. (“Momentus” or the “Company”), a commercial space company offering in-space infrastructure services, and Qosmosys, a new space venture founded in Singapore last year, announced today a service agreement to deliver two cubesats to low lunar orbit as early as 2024 via Momentus’ inaugural lunar mission.

The new contract builds and expands on the agreement announced in January 2021 for delivery of up to four cubesats in low Earth orbit by Momentus’ Vigoride service vehicle, starting in 2022. Qosmosys will expand its novel business ideas to the Moon using a specific bus named Zeus-MS, a version of its Zeus platform it has been developing in cooperation with NuSpace from Singapore, and made specific for lunar missions. Zeus-MS is the precursor to a series of multi-mission platforms that will allow organizations and businesses to host their payloads, and will offer individuals a bespoke, unprecedented line of services to the Moon on regularly scheduled flights.

“We are excited to partner with Momentus again, now onboard Ardoride’s inaugural lunar mission in 2024,” said Francois Dubrulle, CEO of Qosmosys. “Our vision is to make space accessible to all, and Momentus will help us achieve this goal through their efficient orbital services.”

Ardoride, the next generation service vehicle after Vigoride, will extend the range and capabilities of Momentus’s services beginning in 2023.

It is unclear who Qosmosys’ customers are for their lunar Zeus-MS cubesat platform, but I have no doubt they have plenty, many from the university community. For example, universities fund student-built cubesats for educational purposes. Why not make this a project to the Moon, rather than just in Earth orbti? The cost difference would not be much using these new private companies.

Axiom raises $130 million in investment capital

11:41 am

Capitalism in space: The private space station company Axiom announced today that it has obtained $130 million in investment capital during its most recent round of fund-raising.

The funding will allow the company to expand, including doubling its current workforce of about 110 people this year, Michael Suffredini, president and chief executive of Axiom, said in an interview. It will also support quarterly payments to Thales Alenia Space, which is building the pressurized elements of the first modules. The company recently moved into a two-story building in Houston and is buying a new test facility, with plans to establish a campus at Spaceport Houston, also known as Ellington Airport.

“This is a really the major step for us,” he said. “The B round is typically where you get your first large investment, but more importantly than the money is the community of investors that you put together, so that future rounds are largely from those investors.” That group of investors, he said, was “a perfect fit for us and puts us in a good position, however we want to go forward.”

Suffredini also admitted that while helps get those first modules built for launch to ISS in ’24, they will still need “probably between half a billion and a billion dollars” to build their full private space station.

Sounds like a lot, eh? ISS cost about $100 billion, but that is not including the contributions of the U.S.’s international partners. It is also likely a conservative estimate, as it likely does not include any of NASA’s overhead in connection with the station. Construction officially began in 1994, but actually started a decade earlier when President Reagan first proposed its predecessor, the Freedom station, and those costs are not included as well.

So Axiom will build its private station for about a billion, and get it done in about five years. NASA spent anywhere from $100 to $200 billion, and took more than three decades to get it launched and built.

Watching Perseverance’s landing on Mars

9:51 am

Because it will take eleven minutes for radio communications from Mars to reach Earth, no one on Earth will have any direct contact with the American rover Perseverance as comes in to land in Jezero Crater on Mars on February 18th. When NASA broadcasts the landing here on Earth it will already have happened.

Nonetheless, if you want see as soon as possible if the landing was successful, you can go to NASA public channel here at NASA or here at Youtube. I have also embedded the live stream telecast below the fold in this post.

The landing itself is set for about 3:55 pm (Eastern) on Thursday, February 18th. NASA’s coverage is scheduled to begin at 2:15 pm (Eastern). Expect almost everything you watch to be seeped in NASA propaganda, though of course their overview of the rover, its landing, and its landing site will be informative.

One important note: NASA has been selling the false notion that the primary goal of Perseverance is to search for life on Mars, and sadly much of the mainstream press has been repeating this notion blindly. It is simply not true. The rover’s primary goal, first, last, and always, is to gain more knowledge of the geology of Mars and its past history. If along the way the rover detects evidence of life, all for the better, but that is not what it will be focused on doing during its journey in Jezero Crater.
