SpaceX raises another $337 million in investment capital

9:45 am

Capitalism in space: In an SEC filing yesterday SpaceX revealed that it has raised another $337 million in investment capital.

The company raised in 2021 a total of $1.85 billion, and over the last six years has raised close to $7 billion total. While some of that capital is being used to finance its Starlink internet constellation of satellites, most is being funneled into the development of its totally reusable heavy lift Starship/Superheavy rocket.

The eagerness of investors to put money behind SpaceX is a strong vote of confidence in the company, coming from totally independent sources.

Adding in the $2.9 billion dollar contract from NASA for building a lunar lander version of Starship, SpaceX has raised about $10 billion total for building this rocket.

Whether that will be enough of course is not yet known. Based on SpaceX’s past work it should be. That however assumes the federal government’s bureaucracy doesn’t throw a serious wrench in the process, something it right now appears to be doing by stalling the orbital test flight of Starship/Superheavy.

1st stage of Webb sun shield deployment completed

9:29 am

The deployment of the forward and aft pallets required to support the sun shield for the James Webb Space Telescope has apparently been successfully completed.

The link takes you to the website that outlines each step in Webb’s entire 30-day deployment sequence, and is updated to show you the next required step as the process continues. Though I have yet to see any official announcement, this page now shows that both pallets have successfully unfolded and that the next step is removal of the covers that have protected the sun shield membrene during assembly and launch.

Iran launches orbital Simorph rocket, does not reach orbit

3:09 pm

According to Iran’s state run press, it successfully launched its orbital Simorgh rocket on a test suborbital flight today, carrying three payloads to an altitude of 292 miles.

Ahmad Hosseini, an Iranian defense ministry spokesman, said the satellite-bearing rocket named Simorgh, or “Phoenix,” had launched the three cargoes at an altitude of 292 miles (470 km) and at a speed of 7,350 meters (4,5 miles) per second. “The intended research objectives of this launch were achieved,” Hosseini said, in comments broadcast on state television.

“This was done as a preliminary launch … we will have an operational launch soon,” the spokesman added, without further clarifying whether the devices had successfully entered Earth’s orbit.

In 2020 Iran completed an orbital launch using a mobile launcher, which probably used a different solid rocket instead of Simorgh.

However, since Simorgh is intended as an orbital rocket and it did did not reach orbit this time strongly suggests the rocket failed. Since the Iranian press provided images of the rocket in flight soon after launch, the failure possibly occurred at first stage separation followed by ignition of the second stage, a critical moment in a launch where failures often occur.

No matter. Whether it failed or functioned exactly as planned, this launch will provide Iranian engineers valuable information for that inevitable successful orbital flight.

As an orbital rocket designed to launch satellites, Simorgh actually poses less of a threat than that mobile launcher from 2020. Simorgh isn’t really a missile designed to launch bombs. It takes too long to fuel, and its launch site is vulnerable. The mobile launcher used in 2020, likely using solid rockets, is far more dangerous.

The badlands on the floor of Valles Marineris

The badlands on the floor of Valles Marineris
Click for full image.

Cool image time! The recent discovery that there might be a near surface reservoir of ice on the floor the canyon Valles Marineris, near the Martian equator, immediately brought this location to the forefront as a possible site for establishing colonies. The weather will be less harsh than higher latitudes, the low elevation means a thicker atmosphere, and the terrain will be more appealing than the boring flat northern lowlands.

The picture to the right, cropped and reduced to post here, illustrates however the likely difficulties of landing and living on the floor of Valles Marineris. Taken on July 26, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), the photo shows just one small area of the floor of Ius Chasm, the western part of Valles Marineris and about 300 miles to the east of that water reserve.

In this one picture we can see trapped sand dunes in hollows, eroded depressions, mottled terrain resembling stucco, and innumerable cliffs and sinks and plateaus. For the first manned spacecraft to land on Mars, this is not a good first choice. Even later, when the first bases have been built, this terrain would still be forbidding for the early colonists to land in and traverse.

The overview map below shows exactly where this picture is relative to the rest of the Valles Marineris.

U.S. military adds Blue Origin to its point-to-point space cargo development program

9:50 am

Capitalism in space: The U.S. military on December 17th signed an agreement with Blue Origin to add it to its point-to-point space cargo development program.

The command last year signed similar agreements with SpaceX and with Exploration Architecture Corp. (XArc). Blue Origin is the third company to ink a CRADA [as these development contracts are called] for the rocket cargo program.

Under CRADAs, companies agree to share information about their products and capabilities but the government does not commit to buying anything. U.S. TRANSCOM’s analysis of industry data will inform the newly created “rocket cargo” program led by the Air Force Research Laboratory and the U.S. Space Force. The Air Force in its budget proposal for fiscal year 2022 is seeking $47.9 million to conduct studies and rocket cargo demonstrations. [emphasis mine]

I highlight the total budget of this program to show that this is a very small government program. The cash it provides these three companies is nice, but it is chicken feed when compared with the total cost of development. It certainly will not result in a faster pace at Blue Origin in developing its New Glenn rocket, which is presently two years behind schedule with further delays almost certain because its BE-4 rocket engine is not yet ready for mass production.

Whether the program itself is a good thing, or merely another example of government crony capitalism, is open to question. The practicality of using either Starship or New Glenn for cargo transport remains very unproven, especially for New Glenn, which was not designed with such a purpose in mind and cannot land its upper stage on Earth as Starship can.

Starship prototype #20 completes another static fire launchpad test

9:40 am

Capitalism in space: Despite being blocked by the federal government bureauceacy from launching its Starship/Superheavy rocket on its first orbital flight, SpaceX yesterday successfully completed another static fire launchpad test of the 20th prototype of Starship.

It appears that this was the second static fire test that used all six of prototypes’s Raptor engines.

Meanwhile, Superheavy prototype #4 sits on the orbital launchpad, where similar static fire tests were expected but have not yet occurred. Either SpaceX engineers found they needed to additional revisions of the prototype before attempted such a test, which could fire as many as 29 Raptor engines at once, or the company has decided to hold back its testing because the FAA has not yet approved the environmental reassessment for the Boca Chica launch site. Firing the engines on Superheavy before that approval could be used by SpaceX’s environmental enemies as a public relations weapon to help kill the approval entirely.

Personally I think the answer is the former. It is not Elon Musk’s way to cower in fear of others. In fact, he is more likely to push forward, knowing that the publicity from a successful Superheavy static fire test will almost certainly be mostly positive and enthusiastic, thus helping to force politicians to force the bureaucracy to sign off its approval.

Virgin Orbit merger produces only half the investment capital expected

9:28 am

Capitalism in space: It appears that the merger of Virgin Orbit with the special purpose acquisition company (SPAC) NextGen Acquisition II has produced only half the investment capital that had been expected.

The merger had expected to produce $483 million in investment capital for the rocket company. Instead it has produced only $228 million because many shareholders of NextGen cashed out before the merger occurred. Apparently, these shareholders did not have confidence in the Virgin Orbit, and feared their stock value would drop once the merger was completed.

It appears that Virgin Orbit has been stained by the failure of another Richard Branson space company, Virgin Galactic, to deliver on its promises. Virgin Orbit has successfully completed two orbital flights, and is expected to complete a third shortly. Unlike Virgin Galactic, it has done what it said it would, though it took longer than predicted (delays that were not unreasonable considering it was a startup rocket company). Investors have looked at the collapse of Virgin Galactic stocks, and have decided they do not wish to gamble their money on another Branson space company, no matter how successful.

China completes two launches to make 2021 the most active year in rocketry ever

9:16 am

China yesterday completed two different launches from two different spaceports using two different rockets.

First it used its Long March 2D rocket to launch an Earth observation satellite from the Jiuquan Satellite Launch Center in northern China.

Then, a few hours later, a Long March 3B rocket launched a classified military satellite from the Xichang Satellite Launch Center in southwest China.

Both launches dropped first stage boosters in the interior of China. No word on whether either used parachutes or grid fins to better control the stages so that they avoid habitable areas.

These two launches bring China’s total number of successful launches in 2021 to 52, a record for that country and the most any single country has achieved since Russia successfully launched 54 times in 1992 as its high launch rate slowly shut down following the fall of the Soviet Union.

The two launches also bring the total number of successful launches in 2021 to 134, the most in any single year in the entire history of space exploration. The last time global launches reached such numbers was in the 1970s and 1980s, numbers that were produced mostly by the launch of a lot of short term low orbit surveillance satellites by the Soviets, using technology that the U.S. had abandoned in the 1960s as inefficient. It took the collapse of the communist state for Russia to finally cease such launches itself.

Now the high number of launches is increasingly being fueled by commercial competition and profits, though China’s record this year is partly due to the same top down communist set-up similar to the Soviet Union. Even so, the number of competing private rocket companies worldwide is on the rise, and in most places (even China in a few cases), it is those companies that are providing the launch services to the government. Profit and private ownership are the watchwords, and so there is aggressive competition that is lowering the launch cost.

I will have more to say about this in my annual report, which I will publish on Monday, January 3rd.

Slope streaks in frozen lava flows on Mars

12:30 pm

Slope streaks on frozen lava
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on June 5, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a ridgeline at the base of the giant volcano Pavonis Mons, with slope streaks on ridge’s north and south sides.

Slope streaks are a mysterious phenomenon unique to Mars. While they resemble an avalanche, they do not change the topography of the surface at all. They appear to occur randomly year round, fading slowly with time. Also, while most are dark, scientists have also spotted bright slope streaks as well.

Slope streaks also only appear on surfaces covered with a layer of fine dust, something that is obviously the case in the cool image to the right. There is so much dust on the surface here that bedrock only appears at the top of the ridge, peeking out in only a few places.

The location of this image, as shown in the overview map below, adds some additional details.

Deployment of Webb’s critical sunshield has begun

9:03 am

The deployment of the complex sunshield for the James Webb Space Telescope has successfully begun, and if all continues as planned, will continue for the next five days.

Early this afternoon the Webb mission operations team concluded the deployment of the first of two structures that hold within them Webb’s most unpredictable and in many ways complicated component: the sunshield.

The structures – called the Forward and Aft Unitized Pallet Structures – contain the five carefully folded sunshield membranes, plus the cables, pulleys, and release mechanisms that make up Webb’s sunshield. The team completed the deployment of the forward pallet at approximately 1:21 p.m. EST, after beginning the entire process about four hours earlier. The team will now move on to the aft pallet deployment.

Over the next five days the aft pallet must be deployed, along with a tower assembly that will raise the telescope itself away from the sunshield to better keep Webb cold. After this the deployment of the many additional parts of the shield will take place, a process that is probably the most complex in-space spacecraft deployment ever.

It is good news that so far all is proceeding as planned, and gives hope that all will continue to do so.

FAA delays final approval of Starship environmental reassessment till Feb 28th

11:42 am

The FAA has now made it official and announced that the final approval of Starship environmental reassessment will not occur before the end of February, thus preventing any Starship orbital test flights until the spring, at the earliest.

As previously announced, the FAA had planned to release the Final PEA in on December 31, 2021. However, due to the high volume of comments submitted on the Draft PEA, discussions and consultation efforts with consulting parties, the FAA is announcing an update to the schedule. The FAA now plans to release the Final PEA on February 28, 2022.

When the rumors of a delay were first noted last week, I predicted that “Starship’s first orbital flight will not happen until the latter half of ’22, if then.” That prediction is now almost certainly confirmed.

Nor I am not confident the FAA’s environmental reassessment of SpaceX’s launch facility in Boca Chica will be ready even in February. The problem appears to be that the FAA needs to also get the approval of both NOAA and the U.S. Fish & Wildlife agencies, and both appear to be very hostile to SpaceX’s efforts.

In fact, this is beginning to look like the situation in Hawaii with the Thirty Meter Telescope. There protesters blocked the start of construction, and the government, controlled by Democrats, worked with those protesters to step by step keep that obstruction active and working. If so, SpaceX faces a very dangerous situation, as it appears the Biden administration is about to do the same thing to it.

China attacks SpaceX, claiming Starlink satellites threaten its space station

9:16 am

China earlier this month submitted a complaint against SpaceX to the UN, claiming that the company’s Starlink satellites have twice forced it to adjust the orbit of its space station to avoid a collusion.

The note said the incidents “constituted dangers to the life or health of astronauts aboard the China Space Station”.

“The U.S. … ignores its obligations under international treaties, posing a serious threat to the lives and safety of astronauts,” Chinese foreign ministry spokesman Zhao Lijian said at a routine briefing on Tuesday.

The story became news today because there was suddenly a flurry of outrage against SpaceX on Chinese social media, responding to Lijian’s statement, with much of it very likely astroturf posts prompted by the Chinese government itself.

This announcement likely signals that China is getting ready to launch the next module to that station. During that launch the large core stage of the Long March 5B rocket will reach orbit, but only for a few days. It will then crash uncontrolled somewhere on Earth. The Chinese government knows it is going to get a lot of bad press because of this fact, and is likely making this complaint to try to excuse its own bad actions.

The two issues however are not the same. Satellite orbits are very predictable, and any maneuvers required by China to avoid Starlink satellites were very routine. Moreover, if necessary SpaceX can adjust its own satellite orbits to avoid a collusion.

The crash of the Long March 5B core stage however is due entirely to a bad design that does not allow for any controlled maneuvers. Once the stage’s engines shut down after delivering the station module into orbit, they cannot be restarted, as designed. The stage must fall to Earth in an unpredictable manner, threatening every spot it flies over during that orbital decay.

At this time the actual launch date for that Long March 5B launch, carrying the next station module, has not been announced. The astronauts on the station just completed their second spacewalk, doing work to prepare for the arrival of the next module. Its arrival can’t be too far in the future, and this complaint by China today suggests it will be sooner rather than later. When it happens China will face a flurry of justified criticism, and the Xi government likely plans to use this UN complaint then to deflect that criticism.

Upper stage fails during 3rd test launch of Russia’s Angara rocket

8:52 am

In the third test launch of Russia’s new Angara rocket, intended as a replacement of its Proton rocket, the upper stage failed during the launch, placing the dummy satellite in the incorrect orbit that will decay in only a few days.

Launch was a partial failure after the upper stage shut down 2 seconds into the second burn leaving the dummy satellite in an incorrect very low parking orbit of 201 x 179 at an inclination of 63.4 degrees. The dummy spacecraft is likely to re-enter within a few days. The original plan was to use three upper stage burns to take the dummy spacecraft all the way into a “graveyard orbit” a few hundred kilometers above the circa 36,000 km circular geostationary Earth orbit (GEO).

The state-run Russian press TASS has attempted to paint this test flight as a success because the first stage operated as planned, but since the primary purpose of the flight was to test the new upper stage, dubbed Persei, the launch must be considered a failure. As an engineering test, however, this failure simply means they must figure out what went wrong and fly again.

In fact, the only real failure here is the slow pace in which Russia conducts these Angara test flights. This was only the third Angara test launch since 2014, with second occurring six years later in December 2020. That the third test was a year later should be considered unacceptable, and illustrates how the development of this rocket by the Russian government is very comparable to SLS, NASA’s own government rocket: slow, cumbersome, and inefficient.

The failure however means that this launch will not add to the total of successful Russian launches in 2021. The leader board in the 2021 launch race remains the same, with the total launches remaining at 132, tied with 1975 for the most active year in rocketry ever.

50 China
31 SpaceX
23 Russia
7 Europe (Arianespace)

According to an announcement today by Glavcosmos, the government agency that manages Russia’s commercial launches, it expects to launch 10 times next year, with three of those launches managed by Arianespace from French Guiana. This count does not include any Russian military, manned, or government launches, so the overall total will be higher, though it is unlikely to exceed by much this year’s total, and will more likely not match it.

Webb: Course correction burn and main antenna deployment both a success

2:11 pm

Over the weekend engineers for the James Webb Space Telescope successfully completed a course correction burn that put the telescope on route to is planned location a million miles from Earth.

They also successfully deployed the telescope’s main antenna.

Other steps completed on Webb’s first full day in space included the switch-on of temperature sensors and strain gauges on the telescope, used for monitoring Webb’s thermal and structural parameters, NASA said. The antenna release and first mid-course correction burn set the stage for the next step of Webb’s post-launch commissioning — the deployment and tensioning of the observatory’s tennis court-sized sunshield.

These next steps are likely the most risky part of the telescope’s deployment, as it involves the most moving parts and is the most complex. While similar such unfoldings have been done successfully many times before, they have also been the very prone to failure.

The sunshield must work however for Webb to operate. As an infrared telescope, it essentially detects heat, and if it is not well shielded from sunlight its images will be fogged.

The deployment is presently set to begin tomorrow.

Russian Soyuz-2 rocket launches 36 OneWeb satellites

9:42 am

Capitalism in space: A Russian Soyuz-2 rocket today launched another 36 OneWeb satellites into orbit, lifting off from Russia’s Baikonur spaceport in Kazakhstan.

This year, a total of five OneWeb missions were launched from the Vostochny Cosmodrome in eastern Russia, and another two launched from Baikonur. Vostochny is the newest cosmodrome for Russia, while Baikonur is the oldest and originated from the Soviet era.

There was also one launch from French Guiana.

The leaders in the 2021 launch race:

50 China
31 SpaceX
23 Russia
7 Europe (Arianespace)

This was the 132nd successful launch this year, which now ties 2021 with 1975 as the most active year in rocketry since Sputnik. With a possible launches from China (Long March 3B) and Russia (a tentatively scheduled test launch of its Angara rocket today), there is a good chance 2021 will become the most active year ever.

Most important, this activity is only a precursor. Next year should see even more activity.

China’s Long March 4C rocket launches Earth observation satellite

8:16 am

China today completed its 50th launch in 2021, successfully launching an Earth observation satellite into orbit using its Long March 4C rocket.

It also launched a cubesat built by students.

Not only does 50 launches smash its previous yearly launch record, set last year at 35, but it exceeds by 20% the 40 launches China had predicted at the start of the year it would complete in 2021.

The leaders in the 2021 launch race:

50 China
31 SpaceX
22 Russia
7 Europe (Arianespace)

China leads the U.S. 50 to 48 in the national rankings. This was the 131st launch in 2021, the second highest total in a single year since the launch of Sputnik in 1957.

Webb successfully launched

8:13 am

Early this morning an Ariane 5 rocket successfully launched the James Webb Space Telescope from French Guiana.

The key moment that indicated the launch was success was, after Webb was deployed from the rocket’s upper stage, its solar panels deployed and the telescope began receiving power from them.

The launch itself was something that has been done by the Ariane 5 rocket many many times, without failure. Now comes the part of this operation that has never been done before.

Now “30 days of terror” begin, as JWST starts its career in space. First, it will take the space telescope 30 days to reach the start of its halo orbit at L2. On its way, the telescope must unfurl its 18 gold-plated beryllium mirror segments using 132 actuators. It will also have to deploy its five-layer, origami sunshield and cool down to below 50K (-223°C or -370°F) to begin the start of science operations in 2022.

NASA has a webpage that shows the step-by-step deployment, and allows you to see the status at any time during the next 30 days.

After almost twenty years of development and a budget that went 20x over its original estimate, let’s us all hope that Webb deploys properly and begins collecting data as intended. If it does, it will allow astronomers to make ground-breaking discoveries, and we shall gain a better idea of what lies hidden behind that black sky that surrounds us.

As for the 2021 launch race, this is the updated leader board:

49 China
31 SpaceX
22 Russia
7 Europe (Arianespace)

China will likely be the winner in the national rankings, 49 to 48 over the U.S. This was the 130th successful launch in 2021, only the second time in the history of space exploration that the world reached that number of launches in a single year.

Webb telescope reaches launchpad on Ariane 5 + how to watch launch

9:14 am

The James Webb Space Telescope, stacked on top of Arianespace’s Ariane 5 rocket, has finally reached its launchpad in French Guiana after twenty years of development costing 20 times its original budget.

The launch itself is now scheduled for December 25, 2021 at 7:20 am (Eastern). It will be live streamed by both NASA (in English) and Arianespace (with options in English, French, or Spanish).

I have embedded below NASA’s feed. As always, expect NASA to pump you with lots of propaganda during its live stream.

When all is said and done, Webb has the chance to show us things about the universe we’ve never seen before. Optimized for deep space cosmology, it will provide us a window into the earliest moments of the universe’s existence. And is infrared capabilities will allow it to peer into many nearer places obscured by dust with a resolution unmatched by previous telescopes.

Keep your fingers crossed all goes as planned.

China launches two military satellites with its Long March 7A

8:56 am

China today successfully launched two military satellites from its coastal Wenchang spaceport, using its new Long March 7A rocket.

The Long March 7 family of rockets will eventually replace the Long March 2 and 3 families. It can launch from the coast, thus eliminating the need to drop boosters in China’s interior. It has greater capacity. It also uses kerosene and oxygen, not hypergolic fuels that ignite on contact and are very toxic.

The leaders in the 2021 launch race:

49 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

As there no more American launches planned this year, with this launch China wins the 2021 launch race, moving ahead of the U.S. 49 to 48.

This was the 129th launch in 2021. As there are three launches still scheduled — a Russian Angara test launch, a Ariane 5 launch placing Webb in orbit, and a Russian OneWeb launch — the year is likely end up tying or beating 1975 as the most active year in rocketry ever. The Chinese could also launch, as it has in the past done a lot of launches in December.

A detailed review of SLS’s present launch status

10:28 am

Link here. The article provides a detailed look at the engine controllers in the former shuttle engines that SLS is using on its core first stage, including some details about the failed unit and the issues involved in replacing it.

I found this historical data in the article most interesting:

The first attempt to launch Orbiter Atlantis and the STS-43 Shuttle vehicle was scrubbed before dawn on July 24, 1991, when the primary computer, DCU A, failed while propellants were being used loaded into the External Tank. … As a result, the launch was scrubbed to allow replacement of the controller, and the launch was rescheduled for August 1, 1991. The failure analysis of the controller revealed a broken blind lap solder joint connection of the bit jumper to the half stack, which is not a generic design problem.”

According to contemporaneous Shuttle Status Reports issued by NASA Public Affairs at KSC in late July, 1991, after the launch was scrubbed and the External Tank was drained and inerted, access to the engine area for maintenance was established on July 26. The broken engine controller was removed, and a new one was installed on July 27, followed by testing to verify the new controller on July 28; the three-day countdown was started over from the top on July 29 for the next launch attempt on the morning of August 1.

It took NASA less than a week to replace an engine controller in 1991. Now, it appears it might take NASA several months, including testing, to do the same thing on SLS. Moreover, the article suggests that there are other subcontractors and organizations (such as the range safety) that are also having trouble being ready for the presently scheduled mid-February launch.

All in all, this report suggests that SLS will not launch in February, will be delayed until April, with a strong chance that even that April date might not be met.

The report also illustrates the sluggish manner in which NASA operates today. Nothing is done with any speed. No task is done in one day if it can take a week. This is bad management, and also a very dangerous way to operate, as it actually encourages sloppiness because no one is under any pressure to work hard. The result has been endless niggling failures, each of which delays things interminably.

Identity of $28 million bidder for New Shepard flight revealed

9:53 am

Capitalism in space: The person who bid $28 million to win a seat on the first suborbital flight of Blue Origin’s New Shepard spacecraft has now revealed himself.

Justin Sun, the founder and CEO of the blockchain platform Tron, announced today (Dec. 22) that he’s the person who paid $28 million for a seat aboard Blue Origin’s first crewed spaceflight. That mission launched on July 20, carrying Blue Origin founder Jeff Bezos and three other people to suborbital space on the company’s New Shepard spacecraft. The then-unnamed auction winner was not among them, however, remaining groundbound due to scheduling conflicts, Blue Origin representatives said at the time.

But it turns out that Sun’s spaceflight dreams were just deferred, not dashed. The 31-year-old entrepreneur said today that he plans to fly on a New Shepard mission next year, along with five other “space warriors” that he will nominate.

Sun outlined what he’s looking for in a Twitter thread today. One crewmate nominee will be “a prominent figure in the crypto[currency] world,” he said. Another will be a Tron community member “with a strong passion for space,” and another will be a tech entrepreneur. The fourth and fifth nominees will be an artist and a celebrity, respectively.

It is unclear if Blue Origin is giving him six seats for his $28 million, or if Sun is paying additional money. At this time Bezos’ company has not revealed anywhere what it is actually charging for tickets.

Japan’s H-2A rocket launches communications satellite

3:52 pm

Japan today successfully launched a commercial communications satellite using its Mitsubishi-built H-2A rocket.

This was Japan’s third and likely last launch in 2021. Since 2018 its numbers have been low, ranging from 2 to 4, so this total matches that pace. It is an embarrassment for Japan, however, when compared to China and SpaceX.

The leaders in the 2021 launch race remain unchanged:

48 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

The U.S. and China remain tied at 48 in the national rankings. This was the 128th successful launch in 2021, making it the second most active year in the history of rocketry, exceeded only by 1975, when there were 132 successful launches, 98 of which were by the Soviet Union, with the bulk of these being short term low orbit spy satellites.

Cool image time! Curiosity yesterday used its navigation cameras to take a panorama of the view inside Maria Gordon Notch. The mosaic above, created from five images taken by the right navigation camera, shows the view looking south and uphill towards Mount Sharp. The heights of the nearest four hills are likely ranging from 30 to 100 feet.

The red dotted line indicates the planned route out of Gordon Notch and up onto the Greenheugh Pediment. If you click on the panorama to look at the full resolution version, you will see that the exit route looks extemely rough, possibly too rough for Curiosity to handle. How the science team handles this issue will be fascinating to watch in the coming weeks.

The map to the right gives us an overview. The white line is Curiosity’s actual travels. The red dotted line marks the planned route. The yellow lines indicate the area covered by the panorama above.

The most striking feature of this Martian terrain is its stark barrenness. All one can see in all directions are rocks and inanimate geology. There is no life, none at all. On Earth it is practically impossible to find any mountainous spot as barren as this, even in the most extreme and hostile environments.

As I’ve said before, Mars is strange, Mars is wonderful, and above all, Mars is alien.

SpaceX begins testing of launch procedures for Superheavy prototype #4

8:50 am

Capitalism in space: SpaceX began this week the testing of the fueling and launch procedures it will follow for launching the first orbital Superheavy, prototype #4, presently mounted on the orbital launchpad at Boca Chica.

On December 17th, SpaceX subjected Super Heavy B4 to a cryogenic proof test about twice as ambitious as B3’s, filling the booster maybe a sixth of the way with a few hundred tons of liquid nitrogen (LN2). What isn’t clear is if that test also raised the booster’s propellant tanks to flight pressures (6-8 bar or 90-115 psi). If Booster 4 did reach those pressures, the test is even more significant – partially proving that the rocket is ready for flight. On December 21st, SpaceX performed a similar series of cryogenic tests, again partially filling Booster 4 with about the same amount of liquid nitrogen but doing so two or three times in a row. Again, the Super Heavy survived the several-hour ordeal without any obvious issues. Still, a number of additional tests – some even more important – are still in front of SpaceX and Super Heavy B4.

The most obvious is simple enough: SpaceX needs to fully fill a Super Heavy booster for the first time. Depending on the storage situation, that process will likely begin by filling Booster 4 with about 2500 tons (5.5M lb) of liquid nitrogen (LN2) – about two-thirds full. If SpaceX also temporarily fills one of the orbital tank farm’s liquid oxygen (LOx) or methane (LCH4) tanks with nitrogen, it could fully load Booster 4 with around 3500 tons (7.7M lb) of nitrogen. At least according to SpaceX’s own website, that’s about the same weight as the propellant (3400t/7.5M lb) Super Heavy is designed to lift off with. If that full cryoproof goes well, SpaceX will then likely perform one or several wet dress rehearsals, ultimately filling Booster 4 with approximately 2900 tons (6.4M lb) of cryogenic oxygen and 500 tons (1.1M lb) of cryogenic methane.

At some point the company will need to not only fill the booster, it will need to do at least one static fire test of its 29 engines. If all goes well, SpaceX will then mount Starship on top, with the first orbital flight to follow. Musk has said they are aiming for a January launch, but no one should be surprised if it slips to February.

ESA delays Webb launch one day due to weather

8:41 am

The European Space Agency (ESA) announced late yesterday that, due to “adverse weather conditions” in French Guiana, it has delayed the launch of the James Webb Space Telescope on an Ariane 5 rocket one day to December 25th.

The announcement also stated that the final launch readiness review also approved the launch, though no update has yet been issued on the ground control communications problem that had caused a two day delay last week.

Meanwhile, this story and its headline encapsulates the terror I think many astronomers presently feel about this telescope:

Why Astronomers Are “Crying and Throwing Up Everywhere” Over the Upcoming Telescope Launch

The sense is one of helpless panic among astronomers who want to use Webb. They know it will do really cutting edge science, but they also know that many things can go wrong, and the history of the telescope (ten years late and 20x overbudget) will likely make replacing it impossible.

And many things can go wrong. Below is NASA’s video showing the telescope’s complex unfolding, step-by-step, after launch.

FAA approves license for launchpad in Camden, Georgia

9:58 am

Capitalism in space: After years of review, FAA yesterday finally approved a license for building a space launchpad in Camden, Georgia.

The approval however does not mean rockets will begin launching, even in the near future. First, there is the opposition to the spaceport, an opposition based on the simple fact that the rockets have to fly over seven miles over land before reaching the Atlantic Ocean.

About 3,800 people have signed a petition calling for a referendum that would let voters decide whether the county can buy the property. “Virtually from the start, the FAA’s review of Spaceport Camden has been fraught with factual mistakes and legal errors,” Brian Gist, senior attorney for the Southern Environmental Law Center, said in a statement Monday. “We will carefully review the FAA’s decision to ensure that it fully complies with all applicable laws.”

The National Park Service and its parent agency, the U.S. Department of the Interior, also have expressed concerns.

In a July 22 letter to the FAA, the Interior Department said a chance of rockets exploding — with fiery debris raining down on wilderness land on Cumberland Island — creates an “unacceptable risk.” Cumberland Island, with its wild horses and nesting sea turtles, is a popular tourist area off the Georgia coast.

The threat to wildlife by the rocket launches is certainly bogus, as we have more than a half century of evidence at Cape Canaveral that space launches not only do no harm to wildlife, they actually help because they stop development.

The environmental opposition however is actually being used as a weapon by many local residents who really fear the launches because the spaceport seems to them too close to residential areas. They also fear it will also likely interfere with tourism to the coastal beaches and parks that the rockets will fly over, causing them to be shut down during launches.

Because the fears about the nearness of residential areas and the harm to tourism are somewhat legitimate, they illustrate a second reason why this spaceport will likely fail. Why should any rocket company choose this launch site, so close to residential areas and so opposed by many locals, especially when there are now so many other less risky and controversial spaceports to choose from? I suspect very few will do so, and this project will eventually die, even if it finally gets full approval and is built.

SpaceX launches cargo Dragon to ISS using new 1st stage

9:39 am

Capitalism in space: In what will likely be its last launch in 2021, SpaceX early this morning successfully launched a reused Dragon cargo capsule to ISS.

This was the company’s 31st launch in 2021, extending its record for the most launches in a single year by a private company. The launch’s big news however was that the company used a new first stage booster, only the second time in 2021 that it needed to do so (the first was in May). The first stage successfully landed on the drone ship in the Atlantic, completing SpaceX’s 100th successful recovery.

The first such vertical landing had occurred in December 2015, and now six years later and after a hundred vertical landings, SpaceX remains the only orbital rocket entity in the world with such a capability. A very small handful of companies have performed tests with smaller scale prototypes, but that so much time has passed and no one has pushed forward to meet SpaceX’s challenge with even some full scale preliminary test flights does not reflect well on the innovative culture of the world’s rocket industry.

As for SpaceX’s yearly record, 31 launches actually exceeds the number of launches the entire U.S. rocket industry generally managed each year from 1970 through 2017. During much of that time the launch industry was run by NASA in a Soviet-style top-down system that stifled competition and innovation. Beginning in 2008, when SpaceX won its first contract with NASA, that system was abandoned by NASA, switching instead to capitalism and competition, whereby NASA was merely a customer buying its launches from the open market. The positive results from that change have been breath-taking, proving once again that freedom, competition, and private enterprise will win every single time over government programs and communist/socialist ideology.

The leaders in the 2021 launch race:

48 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

The U.S. and China are now tied 48 to 48 in the national rankings. This was the 127th launch in 2021, tying it with 1976 for the second most successful year in rocketry in the history of space exploration. With five more announced launches on the schedule, there is a chance that this year could tie the record year, 132 in 1975.

Curiosity: Through the notch and looking back

11:46 am

Looking back at the entrance to Gordon Notch
Click for full image.

The Mars rover Curiosity has now climbed up into Maria Gordon Notch. The image to the right, reduced to post here, was taken by the rover’s left navigation camera and looks back at the entrance to the notch, with the floor and rim of Gale Crater beyond. The crater floor is about 1,700 feet below and the rim is about 30 miles away.

The red dotted line indicates the path Curiosity took after entering the notch, traveling about 80 feet to the southeast. The rover will continue south inside the notch for another 800 feet or so and then turn west, climbing out of the notch and up onto the Greenheugh Pediment and continuing west until it gets to the base of Gediz Vallis Ridge, a ridge that had been in prominent view about a year ago when the rover was north of it but lower down the mountain. (See the panorama in this February 2021 post.)

Below is another picture from a day earlier, this time taken by the rover’s high resolution mast camera. I think it looks up at the top of the western cliff, but now looks at that cliff after having gone past it slightly.

Class action securities fraud lawsuit filed against Virgin Galactic

8:50 am

Capitalism in space: In what will likely be the first in a number of similar legal actions, a lawsuit was filed against Virgin Galactic earlier this month accusing the company and a number of upper management individuals of securities fraud.

A class action lawsuit was filed in New York on Dec. 7 alleging securities fraud by Virgin Galactic, which went public on the New York Stock Exchange (NYSE) in October 2019 after merging with Chamath Palihapitiya’s Social Capital Hedosophia (SCH).

Named in the lawsuit are Virgin Galactic Holdings, CEO Michael Colglazier, former CEO George Whitesides, former current chief financial officer Doug Ahrens, and former chief financial officer Jon Compagna.

The lawsuit was filed amid years-long delays in the start of commercial human suborbital flights that have caused a sharp decline in the value of the stock. Virgin Galactic began trading on the New York Stock Exchange at an opening price of $12.34 on Oct. 28, 2019. The stock is now trading at $14.46 having previously soared to a high of $62.80.

The article description of the condition of the company’s WhiteKnightTwo carrier plane and its suborbital craft VSS Unity suggests that the likelihood of further tourist flight could be low.

It is also interesting that Richard Branson is not named, as he clearly played a part in any such action. He also conveniently sold most of his stock in the company when its price was on the high end of its roller coaster. It could be the plaintiffs left him out in order to keep his substantial financial big guns from firing back at them.

More lawsuits are expected however, and we should not be surprised if both Branson and Palihapitiya get included at some point.

Japanese tourists return to Earth after 12 days in space

8:35 am

Capitalism in space: Japanese tourists billionaire Yusaku Maezawa and his assistant Yozo Hirano safely returned to Earth yesterday in their Russian Soyuz capsule after spending 12 days on the Russian half of ISS.

Maezawa’s and Hirano’s flight contracts were negotiated by Space Adventures, the only company to date to fly its clients to the International Space Station. Prior to Soyuz MS-20, Space Adventures organized eight flights for seven self-funded astronauts (one flew twice).

Maezawa, 46, is the CEO of Start Today and founder of ZOZO, an online retail clothing business, which he sold to Yahoo! Japan. In 2018, he paid an undisclosed but substantial amount to SpaceX for a circumlunar flight on the company’s still-in-development Starship spacecraft. Maezawa’s “dearMoon” mission, which will fly him and a crew of artists around the moon, is currently targeted for launch in 2023.

Hirano, 36, managed the photography team at ZOZO and is now a film producer at Start Today. In addition to filming Maezawa during the mission, Hirano also took part in human health and performance research on behalf of the Translational Research Institute for Space Health (TRISH) at the Baylor College of Medicine in Houston, Texas. The studies included collecting electrocardiogram readings and using a portable auto-refractor device to collect sight data.

The article also notes a minor record set during this tourist flight. On December 11th a total of 19 people were in space, the most ever, though only for a very short time. Ten were on ISS, three were on China’s space station, and then six were launched on a suborbital flight that day by Blue Origin.

The next commercial tourist flight on the schedule is February’s first Axiom flight to ISS, carrying three customers to ISS for eight days.
