Long March 5B moved to launchpad

8:32 am

The new colonial movement: China’s first Long March 5B rocket has been rolled to its launchpad in advance of its first launch, now expected around May 5th.

The launch was originally scheduled for mid-April, but it appears two recent Chinese launch failures, plus the Wuhan flu, caused the two-three week delay.

The payload is a test prototype of China’s still unnamed next generation manned capsule, which according to the article, will come in two variants:

The spacecraft has two variants of around 14 and 20 metric tons respectively. The mission will test the latter, which is designed for deep space. The mission will be uncrewed and will not include life support systems.

The spacecraft will be able to carry up to six astronauts, or three astronauts and 500 kilograms of cargo to LEO. The three-module Shenzhou can carry three astronauts to LEO and has been used for all six of the country’s crewed missions. The new spacecraft also features improved heat shielding than that used by the Shenzhou. The advanced shielding is required to survive the higher-energy reentries involved deep space missions.

Once in low Earth orbit, the two-module, 8.8-meter-long, 21.6-ton uncrewed spacecraft will use its own propulsion to raise its orbit to an apogee of around 8,000 kilometers. It will then attempt a high-speed reentry to test new heat shielding. The mission also will test avionics, performance in orbit, parachute deployment, a cushioned airbag landing, and recovery. Planned partial reusability — by replacing the heat shielding — will also be tested.

China’s entire manned and planetary program depends on the success of this launch. Should it fail, as did the early launches of the Long March 5, the program will likely experience a one to two year delay.

Europe turns to private enterprise for future space transportation

8:42 am

Capitalism in space: The European Space Agency (ESA) has announced a permanently open call for private companies to develop “space transportation to space, in space, returning from space, or any combination of these.”

To be eligible, the economic operator should demonstrate that its space transportation service is a ‘complete offering’. This means that customers should not need to procure any additional essential service elements such as access to facilities, transport or logistics, to obtain the full service.

The economic operator should take full responsibility for the service project, including finding the funding and resources necessary to develop and deploy the service.

The new space transportation services should justify commercial viability, oriented toward private sector customers, without relying on a guaranteed European institutional demand during the operational phase and with a long-term vision of service provision. Preference will be given to such service projects that are conceived, developed and commercialised in the Participating States.

Though the announcement is filled with the typical hard-to-translate bureaucratic language typical of ESA’s projects, the intent here seems clear. The ESA no longer wishes to do any designing and developing of its rockets, as they have done from the beginning of the space age. This also means they are facing the reality that the Ariane 6 rocket, developed for them by the joint partnership of Airbus and Safran dubbed ArianeGroup, is going to be a financial failure, unable to compete against the lower cost SpaceX and Russian rockets now on the market.

Instead, they are now following what appears to be NASA’s path — the path I outlined in Capitalism in Space — to have ESA act merely as a customer, buying these services from competing private companies (not just ArianeGroup) who will develop the rockets themselves and (most important) own the rockets themselves.

If this is so, it is very good new for the future of space travel. It ups the competition, and it will allow for the development of European rockets able to provide this service at low cost.

The one wrench in the process is that this announcement also includes a bidding process for allowing these new private companies to get development money and technical assistance from ESA. That process appears to have some strings attached that might in the end prevent competing private companies to grow, independent of this governmental body. For example, the submission process allows “ESA to check compliance with Programme objectives and general eligibility. After a positive assessment, ESA will invite the economic operator to submit a full service proposal.” In other words, if you want ESA’s help, you will have to have ESA’s stamp of approval.

Still, this proposal does not require ESA’s help. The agency does appear to be willing to now entertain the use of any rocket system developed by any private operators within the participating ESA’s member nations of Germany, Italy, Norway, Portugal, Romania, Sweden and the United Kingdom.

4th Starship prototype passes tank pressure test

8:41 am

Capitlism in space: SpaceX’s fourth Starship prototype has successfully passed a tank pressure test, the first to do so, allowing engine testing to now begin.

In the end, SN4 passed the cryogenic proof test – hitting 4.9 bar. SpaceX CEO Elon Musk admitted in a tweet that this was “kind of a soft ball…” However, “that’s enough to fly,” he added. It is now expected to move on to engine testing within the coming days.

Currently, SpaceX has three flight-ready Raptor engines waiting for the opportunity to participate in the testing. One of these engines will be installed on SN4. A Raptor engine is not installed until after the cryogenic proof test, as that test uses hydraulic pistons to simulate the forces created by Raptors during flight.

After SpaceX performs the Raptor installation on SN4, teams will need to conduct checkouts of the engine on the vehicle. These will include gimbal, ignitor, and fuel pre-burner tests, among others. Only then will SpaceX be ready to attempt a static fire. April 29 was originally the target for a static fire test, but a one day delay with the cryogenic proof test means that the static fire is now likely targeting no earlier than April 30

All in all, the company’s target of doing a hop with this prototype this summer appears increasingly likely.

China names its 2020 Mars mission

10:19 am

China’s official state-run press today announced that their 2020 Mars mission will be called Tianwen-1, noting that this name will be applied to all further planetary missions.

The link goes to that government state-run press, which provides no further information on Tianwen-1, such as where on Mars its lander/rover will land, its exact launch date, the instruments on board, etc. So far very very few details have been released.

What this propaganda press announcement does do is spout a lot of blather about how wonderful China is, and how we should all be thankful the communists have been in charge there. Here are some snippets to lighten your day:

  • …signifying the Chinese nation’s perseverance in pursuing truth and science
  • …a window for the Chinese public and the world to get a better understanding of China’s aerospace progress.
  • Chinese space engineers and scientists have overcome various difficulties and achieved aerospace development through self-reliance and independent innovation.
  • …promoting human welfare on the basis of equality, mutual benefit, peaceful utilization and inclusive development.

While China’s achievements in space are real (though much of the engineering was stolen or borrowed from others), these propaganda claims are junk and lies. Chinese space engineers are “self-reliant” and have “independence”? Don’t make me laugh. Everything done in their space program is dictated and controlled from the top, by the Chinese government and the Communist Party. No one is free to do anything, without their permission.

As for China’s pursuit of “truth and science”, their behavior during the Wuhan flu epidemic, originating from their country and very possibly caused deliberately or incompetently by them, makes this claim ludicrous on its face. They have lied, arrested scientists, blocked research, and distorted the scope and magnitude of the epidemic from day one.

Even a tiny bit of truth from them, from the beginning, might have prevented the panic that has overtaken the world which in turn appears to have triggered the next great economic depression, what I like to now call the Great Wuhan Depression.

SpaceX rolls out next Starship prototype

9:59 am

Capitalism in space: SpaceX has completed construction of its next Starship prototype and has moved it to its test stand in preparation for further tests.

This is the fourth prototype. If the tank pressure tests go well, they hope to add engines and do a twelve mile hop with this prototype, landing vertically. If not, they will try again with later prototypes. Regardless, the goal is to do that hop this year.

Swarm and Momentus team up to launch and position satellites

9:37 am

Capitalism in space: Swarm, builder of the tiny cubesats dubbed SpaceBees, has teamed up with Momentus to use that company’s Vigoride cubesat upper stage to position its satellites in different orbits after launch.

Under an agreement announced April 22, Momentus will arrange rides for 12 Swarm SpaceBee satellites on a SpaceX Falcon 9 rideshare mission in December 2020 with additional SpaceBee launches scheduled in 2021 and 2022.

To offer global coverage for customers seeking to relay messages through the internet, Swarm satellites must be stationed in different orbital planes and spread out within those orbital planes like a string of pearls, Sara Spangelo, Swarm co-founder and CEO, told SpaceNews.

For the Falcon 9 launch in December, Momentus will not move Swarm SpaceBees to a new orbital plane. In the future, Momentus’ Vigoride in-space shuttle will offer Swarm the option of moving SpaceBees from the rocket’s drop-off point to different locations, Negar Feher, Momentus vice president of product and business development, said by email.

Both companies have raised significant investment capital.

Firefly signs deal with satellite broker Spaceflight

9:29 am

Capitalism in space: Firefly Aerospace has signed a deal whereby the satellite broker Spaceflight will provide the payloads for one of Firefly’s Alpha rocket launches, planned for 2021.

The smallsat launch company already has several other launch contracts, even as development of its rocket proceeds.

Firefly is in the final phases of development of Alpha, and hopes to perform its first launch later this year. Markusic said the company is assembling the first flight vehicle, with plans to perform static-fire tests of the second stage in May and the first stage in June. Once those tests are complete, the vehicles will be shipped to Vandenberg, where work is continuing to modify Space Launch Complex 2 West, a former Delta 2 pad.

A lot can happen between now and 2021, but so far Firefly appears a strong candidate to launch and compete with Rocket Lab.

The first complete geologic map of Moon

9:15 am

Geologic map of Moon

Using data from several recent lunar orbiters, scientists have compiled and now released the first comprehensive geologic map of the Moon.

To create the new digital map, scientists used information from six Apollo-era regional maps along with updated information from recent satellite missions to the moon. The existing historical maps were redrawn to align them with the modern data sets, thus preserving previous observations and interpretations. Along with merging new and old data, USGS researchers also developed a unified description of the stratigraphy, or rock layers, of the moon. This resolved issues from previous maps where rock names, descriptions and ages were sometimes inconsistent.

“This map is a culmination of a decades-long project,” said Corey Fortezzo, USGS geologist and lead author. “It provides vital information for new scientific studies by connecting the exploration of specific sites on the moon with the rest of the lunar surface.”

The image to the right shows the Moon’s near side.

The complete map file is free to download, and I guarantee that scientists and engineers in China are downloading it even as I type, planning to use it to establish their ownership to the Moon’s most valuable real estate that we scouted for them.

SpaceX successfully launches 60 more Starlink satellites

1:28 pm

Capitalism in space: SpaceX today successfully launched 60 more Starlink satellites.

The launch was significant in several ways. They reused the first stage for the fourth time, landing it successfully. They reused the fairing for the second time.

And with this launch, the Falcon 9 has now flown more than the Atlas 5, and has the most launches of any active American rocket.

This flight marks a major point in U.S. launch operations, as Falcon 9 reaches 84 flights to its name and officially takes the mantle from Atlas V as the most flown, currently operational U.S. rocket.

Atlas V began flying on 21 August 2002 and has 83 flights to its name after 18 years — for an annual rate of 4.6 launches. Falcon 9 began flying on 4 June 2010 and will reach 84 flights in just under 10 years with a flight rate of 8.4 launches per year.

That SpaceX overtook the Atlas 5 so quickly indicates exactly how successful SpaceX has been in grabbing market share from all its launch competitors.

I have embedded the video of the launch below the fold.

The leaders in the 2020 launch race:

Russians slash their launch prices by 39%

9:08 am

Capitalism in space: Having lost their entire commercial market share because of SpaceX’s lower prices, the Russians have finally decided to slash their launch prices by 39%.

As the article notes, the cost for a Proton rocket launch was once $100 million. Then SpaceX came along with a $60 million pricetag. At first the Russians poo-pooed this, and did nothing. When their customers started to vanish however they decided to finally compete, so a year ago they cut the Proton price to match SpaceX’s.

Because of SpaceX’s ability to reuse its first stages, however, that $60 million price no longer worked. SpaceX had a year earlier lowered its prices even more, to $50 million, for launches with used first stages.

This new price slash by Roscosmos probably brings their price down to about $36 million, and thus beats SpaceX.

We shall see whether it will attract new customers. It definitely is now cheaper, but it is also less reliable. Russia continues to have serious quality control problems at its manufacturing level.

That SpaceX’s arrival forced a drop in the price of a launch from $100 million to less than $40 million illustrates the beautiful value of freedom and competition. The change is even more spectacular when you consider that ULA, the dominant American launch company before SpaceX, had been charging between $200 to $400 million per launch. For decades the Russians, ULA, and Arianespace refused to compete, working instead as a cartel to keep costs high.

SpaceX has ended this corrupt practice. We now have a competitive launch industry, and the result is that the exploration of the solar system is finally becoming a real possibility.

Correction: I originally called ULA “the only American launch company before SpaceX.” This was not correct, as Orbital Sciences, now part of Northrop Grumman, was also launching satellites. It just was a very minor player, with little impact. It was also excluded from the military’s EELV program, and thus could not launch payloads for them after around 2005.

First manned Dragon flight scheduled for May 27th

10:30 am

Capitalism in space: NASA today officially announced May 27, 2020 as the scheduled launch date for the first manned Dragon flight to ISS, the first time American astronauts will fly from American soil on an American rocket in an American spacecraft since the shuttle was retired almost a decade ago.

The launch is set for 4:32 pm (Eastern), and I am sure will be live streams by both NASA and SpaceX.

SpaceX reuses sections of damaged Starship prototype for next version

9:07 am

Capitalism in space: In building its fourth Starship prototype for testing, SpaceX has decided to reuse large sections of the previous Starship prototype, badly damaged during a pressure test several weeks ago.

On April 15th, eight days after Starship SN3’s [the damaged third prototype] remaining aft section was cut in half, the rearmost half – known as the skirt – was spotted stacked beneath a brand new engine section built for SN4. While confirming that a significant part of SN3 will be reused on SN4, it also indicates that only a less critical SN3 remnant was fit to join SpaceX’s next prototype.

Though they are not reusing the engines from that third prototype, I have full confidence they will, as they were part of the same bottom section of that prototype that was damaged during the test. This statement is incorrect. I had mistakenly assumed that because SpaceX had said it planned actual test hops eventually with this third prototype that three engines were already in place. They were not.

Chang’e-4 and Yutu-2 reactivated for 17th lunar day on Moon’s surface

8:40 am

Engineers have reactivated both the lander Chang’e-4 and the rover Yutu-2 for their seventeenth lunar day on the far side of the Moon.

The report comes from the state-run Chinese press, so of course, it provides no useful new information other than what I wrote above. It did have this bit of Chinese propaganda, however:

The Chang’e-4 mission embodies China’s hope to combine wisdom in space exploration with four payloads developed by the Netherlands, Germany, Sweden and Saudi Arabia. [emphasis mine]

China’s wisdom sure did everyone a lot of good in Wuhan, didn’t it?

JC Penny faces bankruptcy due to Wuhan panic

5:47 pm

The beatings will continue until morale improves: J.C. Penny is now facing bankruptcy because it will unable to meet a due date on a loan because of store closures forced on it by state governors, panicking over the Wuhan flu.

Like many traditional retailers, J.C. Penney’s business has been under pressure in recent years amid declining store traffic and a shift toward digital outlets. The company’s struggles were compounded in recent weeks after the coronavirus pandemic forced the closure of 850 J.C. Penney stores.

With turnaround plans temporarily shelved due to the pandemic, J.C. Penney executives are considering filing for bankruptcy, Reuters reported on Tuesday, citing sources familiar with the matter. While the retailer has enough cash on hand to weather the store closures, bankruptcy protections would allow J.C. Penney to restructure its upcoming debt payments. The company owes nearly $4 billion in long-term debt.

The article did not say how many employees are presently out of work because of the shut down of JC Penny stores.

I think I will start posting these stories, as I see them. There are a lot, and they illustrate that the shut downs are hurting far more people than the Wuhan flu.

Rocket Lab steals Arianespace customer

9:04 am

Capitalism in space: It turns out that a new launch contract won by Rocket Lab this week was actually a payload that was originally going to fly on Arianespace’s Vega rocket.

What Tuesday’s announcement did not include was the fact that the Japanese company [Synspective] shuffled this launch from a Vega rocket onto Electron. The Vega rocket, which had its first failure in 15 launches last July, has yet to return to flight. The spaceport it launches from in French Guiana remains closed due to the coronavirus.

Synspective had signed a major agreement with Arianespace last year to launch what is hoped will become a 25-satellite constellation. It appears that because of the Vega rocket failure, along with its higher price, Rocket Lab is going to get that business instead. That Rocket Lab can provide Synspective a dedicated launch, to the orbit of its choice, also encouraged the switch.

The background of this deal suggests that Rocket Lab’s future is bright, assuming New Zealand and the United States are ever allowed to go back to normal as free and open countries.

Intuitive Machines reveals details of lunar landing mission

9:28 am

Capitalism in space: Intuitive Machines (IM), one of a handful of private companies that NASA has awarded contracts to build lunar landers of the agency’s science instruments, yesterday revealed the landing site and launch date of its first mission to the Moon.

IM will launch the Nova-C lander in October 2021 on a SpaceX Falcon 9 rocket. The target landing site is Vallis Schröteri (Schröter’s Valley) in the Moon’s Oceanus Procellarum (Ocean of Storms). The company said the site is “flat, free of craters and rocks, and has abundant sunlight” throughout the 14-day mission.

Five NASA payloads and others from commercial customers will be aboard, but IM did not specify what they are. Nova-C can take 100 kilograms to the lunar surface and provide 200 watts of power. Nova-C is based on NASA’s Project M lunar lander and Project Morpheus, which were designed, developed and tested by Johnson Space Center to demonstrate planetary landing technologies. The core team that developed Morpheus left government and founded IM.

Because the lander belongs to Intuitive Machines, not NASA, they have the right to sell their spare payload space to others, increasing their profits above what NASA will pay them. This shifts control of the mission from NASA to the private company, and in the long run will encourage the development of a private unmanned lunar landing industry.

Nor is IM alone in this. NASA has purchased landers from Astrobotics and Masten, with Astrobotics aiming for a 2021 landing and Masten in 2022. Both also have spare payload space, and are offering this to others.

I expect at a minimum some universities will make a deal. Rather than have their students build an orbiting cubesat for training and education, now they can have them build a science instrument that will land on the Moon.

First manned Dragon mission slips to end of May

9:12 am

Capitalism in space: According to NASA administrator Jim Bridenstine, the first manned flight of SpaceX’s Dragon capsule will now occur at the end of May, not mid-May, and will last two or three months.

“I think we’re really good shape,” Bridenstine said in an interview Thursday. “I’m fairly confident that we can launch at the end of May. If we do slip, it’ll probably be into June. It won’t be much.”

The article at the link also reveals that the two astronauts will spend between two to three months on board ISS, not two weeks as originally planned.

Virgin Orbit completes capture-carry test of LauncherOne

8:47 am

Capitalism in space: Virgin Orbit yesterday completed the first capture-carry test of LauncherOne with it attached to the company’s 747 loaded with cryogenic materials.

In previous flight tests, the booster’s tanks were filled with water, which is much warmer than LOX.

For this cryogenic test, Virgin Orbit substituted liquid nitrogen for the LOX as a safety precaution. “So, for this end-to-end rehearsal, we’ll have liquid nitrogen — which is very similar in temperature to liquid oxygen, but which would pose less of a risk in case anything were to go wrong despite all of our planning — in our LOX tanks for both stages,” Virgin Orbit wrote in a mission update.

They say this was their last test prior to LauncherOne’s maiden flight. They have not yet set a date for that flight.

This maiden flight was first supposed to happen in 2018, but in that year development of this rocket slowed to a snail’s pace, probably because they had lost a major launch contract.

The contract award only two days ago from the Space Force will likely reinvigorate Virgin Orbit.

My 2016 prediction that Virgin Orbit would make its first operational flight before Virgin Galactic, even though Virgin Galactic had been started development of SpaceShipOne more than a decade earlier, is still holding. The race now appears to be neck-in-neck, as Virgin Galactic claims it will do operational flights this year. We shall see.

SpaceX moves forward on Starlink launch April 16

9:55 am

Capitalism in space: Despite the recent postponement by customers of two other planned launches because of the Wuhan panic, SpaceX appears to be moving ahead with plans to launch another sixty of its own Starlink satellites on April 16.

According to one unconfirmed news report, six SpaceX employees have tested positive for coronavirus. The company has not commented, however, either on this report or on its own internal policies for dealing with the Wuhan panic.

The Space Force meanwhile has not shut down its range operations in Florida, thus allowing launches from anyone to go forward.

Masten’s lunar lander wins NASA contract

9:46 am

Capitalism in space: Masten’s XL-1 lunar lander has won a NASA contract to bring a suite of science instruments to the Moon’s south polar regions, the launch targeted for December 2022.

The company also hopes to sell payload space on the lander to other customers.

Masten won a task order for NASA’s Commercial Lunar Payload Services (CLPS) program valued at $75.9 million. Masten will deliver nine science and technology demonstration payloads to the lunar surface near the south pole by December 2022 on the company’s XL-1 lander.

The CLPS payloads, with a mass of about 80 kilograms, will serve as the initial, anchor customer for that mission, Sean Mahoney, chief executive of Masten, said in an interview. He said there are “hundreds” of kilograms of additional payload space available on the lander, and that the company is working to line up additional customers.

Masten is now the third private company with an active contract with NASA to land science payloads on the Moon. Astrobotic and Intuitive Machines are the others, with their missions targeting 2021 for launch.

Rocket Lab tests 1st stage capture using helicopters

9:19 am

Capitalism in space: In early March, prior to the shutdown of New Zealand due to the Wuhan panic, Rocket Lab successfully completed a test whereby one helicopter dropped a dummy first stage over the ocean, the stage’s parachutes released to slow it down, and then a second helicopter captured it and gently transported and deposited it safely on land.

This test was part of the company’s effort to recovery its first stages so they can be reused. Because of their small size and the difficulty of developing the software, they have decided that a vertical landing is not economical. This test however shows that capturing the stage by parachute is possible. The real trick will be getting the first stage back through the atmosphere to an expected target spot and be able to release its parachutes. Proving that part of the effort will have to wait until the panic is over and New Zealand releases its citizens from house arrest.

I have embedded video of the test below the fold.

Russia hostile to Trump declaration to promote private enterprise in space

9:33 am

Russia today issued the first international response to the Trump executive order yesterday calling for private enterprise and property in space, and that response was decidedly negative.

Attempts to seize the territories of other planets are harmful to international cooperation, Deputy Director General of Roscosmos for International Cooperation Sergey Saveliev said on Tuesday. “Attempts to expropriate outer space and aggressive plans to actually seize territories of other planets hardly set the countries for fruitful cooperation,” Saveliev said.

He recalled that there were examples in history when one country decided to start seizing territories in its interests. “Everyone remembers what came of it,” Saveliev added.

Part of the goal of Trump’s order was to try to garner international support for the idea of allowing private property in space. The Russian response today suggests that they will not go along, and instead will use the words of the Outer Space Treaty to block such rights.

As I have been saying for years, the real solution is to pull out of the treaty. It forbids us from establishing our laws anywhere in space, which means future space-farers will be second class citizens, with their only rights determined by the UN, not the Bill of Rights.

Boeing to do second unmanned test flight of Starliner

12:59 am

Capitalism in space: Boeing officials said yesterday that they now plan a second unmanned demo mission to ISS of their Starliner manned capsule in order to make sure they have cleared up all the issues that plagued the first unmanned flight in December.

The company on Monday confirmed a report in the Washington Post that it will fly a second uncrewed demonstration mission — which Boeing calls an Orbital Flight Test — before astronauts ride a Starliner into orbit.

“We have chosen to refly our Orbital Flight Test to demonstrate the quality of the Starliner system,” Boeing said in a statement Monay. “Flying another uncrewed flight will allow us to complete all flight test objectives and evaluate the performance of the second Starliner vehicle at no cost to the taxpayer. We will then proceed to the tremendous responsibility and privilege of flying astronauts to the International Space Station.”

Right now they are aiming for an October/November launch date.

Astra furloughs and lays off a fifth of its workforce

9:08 am

The smallsat rocket company Astra Space recently reduced its workforce from 150 to 120, with most of those let go furloughed for three months during the Wuhan flu panic with some laid off entirely.

This reduction appears due mostly because of the panic, as it has killed their efforts to raise more investment capital. However, the “anomaly” that caused the complete loss of a rocket during countdown a few weeks ago might also have contributed. According to this article, which gives some more details of that “anomaly,” which apparently was a fire that destroyed the rocket, caused by “an unfortunate mistake.”

Third Starship prototype collapses during tank pressure test

8:44 am

During the final part of a tank pressure test the third SpaceX Starship prototype apparently collapsed, its outer welded hull failing.

Video below the fold. The prototype is on the right, and it appears it fall inward along its hull welds.

The SN3 (Serial Number 3) vehicle incorporated lessons learned from previous vehicles and test articles, and took advantage of improved manufacturing techniques and expanded facilities at SpaceX’s South Texas launch facility.

The next round of testing began this week with cryogenic proof testing. These tests saw the vehicle filled with liquid nitrogen at cryogenic temperatures and flight pressures. Proof testing began in Thursday and continued through to Friday morning when SN3 failed during what appeared to be the end of the test.

With Elon Musk noting “we will see what data review says in the morning, but this may have been a test configuration mistake,” on Twitter and the first-look observations, the fault may have been related to detanking, rather than another failure under pressure.

I’m no engineer, so I wonder how detanking could cause such a failure.

SpaceX bans use of Zoom by employees

10:18 am

For security reasons, SpaceX has banned its employees from using Zoom for video conferencing or communications.

Elon Musk’s rocket company SpaceX has banned its employees from using video conferencing app Zoom, citing “significant privacy and security concerns,” according to a memo seen by Reuters, days after U.S. law enforcement warned users about the security of the popular app.

…The Federal Bureau of Investigation’s Boston office on Monday issued a warning about Zoom, telling users not to make meetings on the site public or share links widely after it received two reports of unidentified individuals invading school sessions, a phenomenon known as “zoombombing.”

Investigative news site The Intercept on Tuesday reported that Zoom video is not end-to-end encrypted between meeting participants, and that the company could view sessions.

It appears that Musk’s concern is that someone might use Zoom’s security weaknesses to do some industrial spying. Based on what I have read about Zoom, it seems to me that Musk’s concern is valid.

Momentus wins contract with Taiwan university

9:58 am

Capitalism in space: Momentus, a company that sells a small upper stage designed to provide orbital transportation for cubesats, has won a new contract with Taiwan university.

Under the agreement, Momentus will provide in-space transportation for a satellite mission called Intelligent Remote-Sensing and Internet Satellite (IRIS)-A. Odysseus is providing pre-launch testing and arranging launch services for the IRIS-A mission developed by Taiwan’s National Cheng Kung University. IRIS-A is designed to test technology to improve the quality of downlink signals.

In spite of the COVID-19 pandemic, Momentus executives say they are continuing to sign up customers interested in traveling on Vigoride, a vehicle to move small satellites from their drop-off point in orbit to their final destination.

The article does not say what rocket will launch the cubesat plus Vigoride, but Momentus has a contract with SpaceX to launch five cubesats as secondary payloads, so this is probably how the payload will reach orbit.

Normally cubesats launched as secondary payloads on big rockets like the Falcon 9 have very limited options on the orbits they can reach. The primary payload’s requirements are what rules. The idea here is Vigoride takes over once deployed and moves the satellite to the exact orbit needed. If Momentus is successful in doing this it will give cubesat makers many more launch options. It will also put more competitive pressure on the smallsat rockets like Rocket Lab’s Electron, since its main selling point is how it can put cubesats where they want to go, something that bigger rockets have not been able to do, up until now.

NASA selects full crew for first operational Dragon mission

10:23 am

Even though SpaceX’s first demonstration manned mission to ISS has not yet occurred, NASA yesterday announced the selection of the full four person crew for the second flight, set for later this year and intended as the first operational mission to ISS, lasting six months.

This announcement tells us several things, all good. First, it appears NASA has now definitely decided that the demo mission, presently scheduled for mid-May, will be a short-term mission. They had considered making it a six-month mission, but it now appears they have concluded doing so will delay the demo launch too much.

Second, that NASA is solidifying its plans for that operational flight, the second for Dragon, including a tentative launch date later in 2020, is further evidence that they intend to go through with the demo mission in mid-May.

Finally, it appears that NASA has decided that it will not buy more seats on Russian Soyuz capsules, something that they had previously hinted they needed to do because the agency was worried the American capsules would not be ready this year. The article describes the negotiations on-going with the Russians about the use of Dragon, as well as the future use by Americans of Soyuz. NASA wishes to have astronauts from both countries fly on both spacecraft (Starliner too, once operational), but Russia is as yet reluctant to fly its astronauts on Dragon. They want to see that spacecraft complete more missions successfully.

Regardless, future flights of Americans on Soyuz will cost NASA nothing, as the agency wishes to trade the seats on the U.S. capsules one-for-one for the seats on Soyuz. It also means that NASA has decided it doesn’t need to buy Soyuz flights anymore, as it now expects Dragon to become operational this year.
