Unintentional ASMR – Very Thorough Table Tennis Racket Tester

An evening pause: An example of the complexity of technology required to set fair standards in official competitive games — in this case ping pong — that no one ever thinks about.

I especially like the passion and dedication the tester brings to his work, to make sure all is right.

Two space companies fight in the Ukraine war

Two stories yesterday illustrate how Russia’s invasion of the Ukraine has forced two different space companies, one American and the other Ukrainian, to adapt and change in order to help the Ukraine.

First, SpaceX once again demonstrated its ability to adapt, revise, and even redesign its products with lightning speed, based on unexpected facts on the ground.

After SpaceX sent Starlink terminals to Ukraine in February in an apparent effort to help Ukraine maintain its internet connection amid war with Russia, SpaceX founder Elon Musk claimed that Russia had jammed Starlink terminals in the country for hours at a time. After a software update, Starlink was operating normally, said Musk, who added on March 25 that the constellation had “resisted all hacking & jamming attempts” in Ukraine.

The speed in which SpaceX overcame Russia’s jamming was so fast that the American military was gob-smacked.

“From an EW technologist perspective, that is fantastic. That paradigm and how they did that is kind of eyewatering to me,” said Dave Tremper, director of electronic warfare for the Pentagon’s acquisition office. “The way that Starlink was able to upgrade when a threat showed up, we need to be able to have that ability. We have to be able to change our electromagnetic posture, to be able to change very dynamically what we’re trying to do without losing capability along the way.”

In other words, the Pentagon is incapable at present of doing the same thing, and now realizes it should be. The real lesson this government entity should take from this however is to stop trying to build anything at all. Hire the private sector. Let it do the work. Competing privately owned companies can always beat the government at this game. Always.

The second story involves the Ukrainian company Lunar Research Service, which until the war had used its 3D-printing technology to build components for a number of space missions, including lunar rovers. That changed immediately with the invasion.

The start-up was just about to ship its first batch of nanosatellites to their Kickstarter backers, but priorities changed within days, the company’s chief technology officer Dmytro Khmara told Space.com in an email. Instead of going to the customers, the nanosatellites were taken apart and the components handed over to the military.

Since then the company has reprogrammed its 3D printers to build parts for the Ukrainian military, including gun parts.

Though company officials say they hope to return to building components for space, circumstances might not allow it. As long as the war grinds on, the company’s profits will be found in helping the Ukriane’s military.

Astrobotics unveils nearly complete Peregrine lunar lander

Capitalism in space: Astrobotics yesterday unveiled its nearly complete Peregrine lunar lander, scheduled for launch later this year on the first launch of ULA’s new Vulcan rocket.

The lander is still being assembled, said John Thornton, chief executive of Astrobotic. Remaining work includes installation of its solar panels, two fuel tanks and decks holding payloads. The engines are “just about done,” he said, and will soon be installed.

He was optimistic that remaining work will be done quickly. “In just a couple months’ time, this will be heading out to environmental testing,” he said, followed by shipment to the launch site late this year.

This announcement now strongly suggests that Peregrine would not have been ready for Vulcan’s original launch date in late 2021. Since then the delays by Blue Origin in developing Vulcan’s first stage BE-4 engine has pushed the rocket’s first launch back by more than a year, time that apparently Astrobotics needed to finish Peregrine.

NASA awards contracts to six companies for its future orbital communications

Capitalism in space: NASA has awarded development contracts to six different companies to test the technology for providing the agency orbital communications for its manned missions, replacing the NASA-built TDRS satellite constellation.

In addition to SpaceX and Project Kuiper, the contractors include U.S.-based ventures representing Inmarsat, SES, Telesat and Viasat. Each venture will be required to complete technology development and in-space demonstrations by 2025 to prove that its system can deliver robust, reliable and cost-effective services — including the ability for new high-rate and high-capacity two-way links.

NASA would follow up by negotiating long-term contracts with multiple vendors to acquire services for near-Earth operations by 2030, while phasing out satellite communications systems owned and operated by the space agency.

Because NASA’s own station will likely be gone when these new in-space communications constellations become operational, their likely customers will not be NASA but the private space stations now under development. NASA is thus accepting responsibility for paying the cost for getting this communications need developed, for all the private companies. While the private space stations should eventually pay for using and building these constellations, it makes sense for NASA to get this started. No one company could likely afford or even be willing to pay the entire cost, and getting them all to work out an arrangement now would be difficult. NASA in turn can get it done now, and then later negotiate contracts with the private stations to pay for its construction and use.

OneWeb signs deal to launch additional satellites using India’s GSLV rocket

Capitalism in space: OneWeb yesterday announced that it has signed a contract with New Space India, the commercial arm of India’s space agency, to launch additional satellites using that nation’s GSLV rocket.

From the company’s press release:

The first launch with New Space India is anticipated in 2022 from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launches will add to OneWeb’s total in-orbit constellation of 428 satellites, 66 per cent of the planned total fleet, to build a global network that will deliver high-speed, low-latency connectivity.

The company refused to release any additional details. The deal however clearly indicates two things. First, OneWeb wants an alternative to using SpaceX for launching the satellites that the Russians had been previously contracted to put in space. This gives it flexibility should one or another company have issues. For example, SpaceX simply might not have the immediate capacity to launch all these satellites as quickly as OneWeb wants. This second deal distributes that capacity across two launch vendors.

Second, it is likely in the long run that India is going to get a lot of business from OneWeb. This gain for India is Russia’s total loss. The deal will also help get India out of its extended panic over the Wuhan flu. Since the arrival of COVID India’s space industry has ground to a halt, completing few launches. The OneWeb deal might force it to come back to life.

New schedule announced for landing of AX-1 crew and launch of NASA crew

Because of poor weather at the splashdown points on Earth, SpaceX and NASA have worked out a new schedule for both the landing of Axiom’s first passenger flight to ISS as well as NASA’s next launch of astronauts.

The integrated NASA, Axiom Space, and SpaceX teams have agreed on a plan for the Axiom Mission 1 (Ax-1) crew to undock from the International Space Station at 8:35 p.m. EDT Saturday, April 23, for a splashdown off the coast of Florida about 1:46 p.m. Sunday, April 24. The decision was made based on the best weather for splashdown of the first private astronaut mission to visit the International Space Station and the return trajectory required to bring the crew and the SpaceX Dragon Endeavour spacecraft back to Earth safely.

…The departure of Dragon Endeavour from the space station will clear the docking port for the arrival of Dragon Freedom and NASA’s SpaceX Crew-4 astronauts. The earliest potential launch opportunity for the Crew-4 mission is 4:15 a.m. Tuesday, April 26, with additional opportunities Wednesday, April 27, and Thursday, April 28. These launch opportunities are undergoing a more detailed program review to ensure they align with integrated operational timelines. The teams want to provide a two-day gap after Ax-1 return for data reviews from splashdown and to prepare for the Crew-4 launch, including the staging of recovery assets.

If the landing occurs on April 23rd as now planned, the Axiom passengers will have spent fifteen days in space, about four more than originally planned.

Spinlaunch releases video of its 7th test launch

Capitalism in space: Spinlaunch on April 18th released a video providing what it calls “an inside look” at the company’s procedures during its 7th test launch on March 22, 2022.

I have embedded the video below. Note that on this test launch, the projectile was lifted to only about 30,000 feet, which does not qualify it as a suborbital space flight. Still, the video also indicates that their test projectile not only survived the launch’s extremely high accelerations, reaching a speed of 1,200 miles per hour in mere seconds, but once it hit the ground it was in good enough shape to reuse.

The video also reveals one other interesting fact. Their mission control consisted of only two people, significantly less than the mission control staffs used by the commercial rocket companies, which are themselves significantly less that the mission control teams that NASA has used.

Delta testing Starlink use on its airplanes

Capitalism in space: The CEO of Delta has revealed that the airline company is testing Starlink as a method for providing its passengers internet access during flights.

Starlink officials have said they are also discussing this possibility with several airlines. It has also sought regulatory approval from the FCC, and will also need it from the FAA before officially proceeding.

The request to the FCC was made in March 2021, more than a year ago, and appears to have not yet been approved. Moreover, there have been signs that the FCC has been slow-walking other Starlink license requests. These facts, combined with the delays forced on SpaceX by the FAA, provides further circumstantial evidence that the federal bureaucracy under the Biden administration is working to block the success of Elon Musk’s space companies.

Axiom again cancels return of manned mission due to weather

Capitalism in space: Because of continuing poor weather on Earth, SpaceX & Axiom once again canceled the planned return of manned mission yesterday.

At the moment there is no word on when SpaceX’s Endeavour capsule will undock and bring its passengers home. Since a NASA crew is preparing for launch on Saturday, April 23rd, we should expect that return to occur beforehand.

This article from Israel about the delay, which also focuses on the flight of Israeli businessman Eytan Stibbe, had this interesting tidbit:

Businessmen Stibbe, American Larry Connor of Ohio, and Canadian Mark Pathy have paid $55 million apiece for the rocket ride. The visitors’ tickets include access to all but the Russian portion of the space station. [emphasis mine]

When the Russians launched Dennis Tito and other tourists in 2000s, I am unsure if those tourists were allowed in the American portion of the station. My guess would be yes, but that would be a guess, and very easily wrong. During the two tourist flights to ISS in October and December it is also unclear if those passengers had access to the American half. Considering the competition for tourist flights that now exists, I would suspect no.

Return of first Axiom commercial crew from ISS delayed

Capitalism in space: Because of iffy weather at their planned splashdown point, SpaceX and Axiom have delayed the return of Axiom’s first commercial crew at ISS so that they will splashdown tomorrow.

Weather permitting, the four-member private astronaut crew now is targeted to undock at about 10 p.m. Tuesday, April 19, to begin the journey home with splashdown off the coast of Florida no earlier than approximately 3:24 p.m. EDT Wednesday, April 20.

If weather remains an issue, the return to Earth of Endeavour could be delayed further.

Don’t launch it! Don’t spin it! Fire your orbital payloads from a gun!

Capitalism in space: It appears there is another company attempting to develop a different radical method for getting payloads into space. Instead of launching them on a rocket, or spinning them up to escape velocity (as Spinlaunch proposes), the startup Green Launch proposes to fire them from a cannon!

Green Launch COO and Chief Science officer Dr. John W. Hunter directed the Super High Altitude Research Project (SHARP) program at the Lawrence Livermore National Laboratory some 30 years ago, and in the process led the development of the world’s largest and most powerful “hydrogen impulse launcher.”

This is effectively a long tube, filled with hydrogen, with helium and oxygen mixed in, and a projectile in front of it. When this gas cannon is fired, the gases expand extremely rapidly, and the projectile gets an enormous kick in the backside. The SHARP program built and tested a 400-foot (122-m) impulse launcher in 1992, breaking all railgun-style electric launcher records for energy and velocity, and launching payloads (including hypersonic scramjet test engines) with muzzle velocities up to Mach 9.

This approach, says Green Launch Business Development Director Eric Robinson, scales up far better than a spinning accelerator like the SpinLaunch system.

On its website the company claims this technology could not only be used for bulk payloads, like oxygen or water, but also “acceleration-tolerant payloads in the cube-sat class and smaller.” I am not sure how any complex hardware in any satellite, no matter how small, could withstand such accelerations, but once again, such technology could provide a cheap way to get simple cargo into orbit.

Below is a video of the company’s December 21, 2021 vertical test.

Boeing and NASA set May 19th for second Starliner unmanned demo launch

NASA yesterday announced May 19th as the new launch date for Boeing’s second attempt to complete the first unmanned Starliner demo mission to ISS.

The uncrewed mission will test the end-to-end capabilities of the Starliner spacecraft and Atlas V rocket from launch to docking and return to Earth at one of five designated landing zones in the western United States. Following a successful completion of the OFT-2 mission, NASA and Boeing will determine a launch window for NASA’s Boeing Crew Flight Test (CFT), Starliner’s first flight with astronauts aboard.

The first unmanned demo flight in December 2019 failed to dock with ISS and had to be cut short due to serious software issues. The launch of the second unmanned demo flight was scrubbed mere hours before launch in August of 2021 due to serious valve issues.

Thus, Boeing’s manned capsule is more than two years behind schedule. Not only has Boeing had to pay more than $400 million for a second demo mission, the delays have caused a lot of business with NASA and with tourists to instead go to SpaceX. Hopefully, the company has finally fixed all issues and will succeed and begin manned operations later this year.
