How private enterprise is solving the vulnerability of satellites to military attack

Link here. The essay provides a nice overview of the U.S. military’s present conundrum on protecting all American satellites in orbit, not just military ones, and what it is beginning to do to solve it, now that the Space Force exists.

The approach is following three paths, with only the last two having any hope of success. First, the Biden administration is trying diplomacy to convince space-faring nations to ban future anti-satellite tests. This approach has really little chance of success.

The other two avenues involve innovations from private enterprise, launching many small satellites as part of a large constellation and in-orbit servicing, repair, and refueling. The first creates redundancy, making it difficult for any enemy power to easily destroy U.S. assets. The second provides capabilities for both fixing important satellites as well as attacking our enemy’s without causing space junk. Both will become common in the coming years, and thus will become very viable tools for military use.

Musk: Starship orbital attempt by November, at the latest

According to a tweet yesterday by Elon Musk, SpaceX engineers will likely have the first orbital prototypes of Starship and Superheavy ready for the orbital attempt either late in October, or by November. His full tweet:

Late next month maybe, but November seems highly likely. We will have two boosters & ships ready for orbital flight by then, with full stack production at roughly one every two months. [emphasis mine]

The highlighted words are the most significant. SpaceX is not building one rocket for test, like NASA has done with SLS. It is building an assembly line of test rockets, so that it can do a fast series of test launches plus upgrades, leading to quick and reliable operations. Should any one rocket launch fail, the company will speedily move on to the next, with little or no delay.

Should SLS fail in its first test launch sometime in the next month, NASA has no back-up. The entire program will be shattered, with no easy way to recover.

Nova Scotia spaceport signs deal with British rocket startup

Capitalism in space: Maritime Launch Services, the company that is building a spaceport in Nova Scotia, has signed an agreement with the British rocket startup Skyrora, naming its Skyrora-XL rocket as one of the launch providers for that spaceport.

As part of the agreement, Maritime Launch will purchase the vehicles and vehicle support staff from Skyrora for their satellite clients. Spaceport Nova Scotia will provide Skyrora a launch pad, ground and operations support, public safety services, regulatory approvals and mission integration facilities and staff. Skyrora will supply the launch vehicle, mobile launch complex, and launch operations support team to Maritime Launch.

Unlike other new spaceports, Maritime is running Spaceport Nova Scotia a bit differently. Most new spaceports simply provide a launch site for rocket companies. Maritime instead wants to offer satellite companies a full service spaceport, including the rocket. Initially the plan was to use a Ukrainian-built rocket, Cyclone-4M, as part of the service, but the Russian invasion of the Ukraine has made its availability uncertain.

This deal gives Maritime a new option to offer satellite companies. However, the Cyclone-4M was already somewhat tested, as it was an upgrade of the Ukrainian Tsiklon-4 rocket, which has already launched. Skyrora is only a startup, and has not yet flown.

Launch startup Spinlaunch raises $71 million more in private investment capital

Spinlaunch prototype suborbital launcher
Spinlaunch’s prototype launcher

Capitalism in space: The radical launch startup company Spinlaunch announced yesterday that it has raised an additional $71 million in private investment capital, bringing the total it has raised to $150 million.

Unlike the many rocket startups, Spinlaunch proposes launching payloads using a centrifuge. The image to the right is of its prototype smaller scale launcher, which has already completed several test launches.

The company claims its full scale launcher will begin operations by 2026, but it has not yet revealed where it will be built, which means construction has not yet begun.

Such a launch system cannot be used by any satellite with delicate equipment. The g-forces during launch are too high. However, for getting bulk cargo, like water and fuel into orbit, such a system could become very profitable, if it can be made operational.

Saudi Arabia buys two seats on Dragon for Axiom commercial flight to ISS

Capitalism in space: According to an as-yet unconfirmed story today by Reuters, Saudi Arabia has purchased two seats on a SpaceX Dragon capsule as part of an Axiom commercial flight to ISS.

The sources for the story are all anonymous, and no one from Axiom or SpaceX or Saudi Arabia has confirmed it. Nonetheless, it seems entirely plausible, since Saudi Arabia has made it clear it is considering such a mission and Axiom and SpaceX are eager to sell tickets.

OneWeb announces delivery of 36 satellites to India for launch

Capitalism in space: OneWeb yesterday announced the delivery of 36 satellites to India for launch on that nation’s biggest rocket, the GSLV-Mark3.

Though no date for launch was mentioned, the press release did say this:

One additional launch will take place this year and three more are targeted for early next year to complete the constellation.

This suggests two launches before the end of the year, one by India with the second already contracted to SpaceX. As for the three launches next year, it is unclear yet who will launch them. OneWeb has contracts with SpaceX, Relativity, and NewSpace India Limited (NSIL), the commercial arm of India’s government space program which is doing this year’s GSLV launch. While Relativity has not yet launched, either SpaceX or NSIL could handle those launches for sure next year.

Hydrogen leak detected during today’s SLS tank test

Though engineers have apparently overcome the issue so that today’s tank test of NASA’s SLS rocket can continue, a hydrogen leak was nonetheless detected during fueling.

The fueling tank test is not yet complete.

At this moment I cannot imagine the military’s range office will allow NASA to launch on September 27th, as the agency has requested. To do so will require the range to ignore the possibility that the flight termination is inoperable, as its batteries are past their use-by date by almost a month. Combined with these ongoing leak issues, it would be irresponsible to do otherwise.

Russia launches three astronauts to ISS; China launches Earth observation satellite

Russia today successfully used its Soyuz-2 rocket to launch three astronauts to ISS, two Russians and an American flying as part of the NASA-Roscosmos barter deal whereby each agency flies an astronaut from the other in order to make sure everyone knows how to use each other’s equipment.

China in turn today used its Long March 2D rocket to launch an Earth observations satellite into orbit.

The leaders in the 2022 launch race:

42 SpaceX
38 China
12 Russia
7 Rocket Lab
5 ULA

American private enterprise still leads China 58 to 38 in the national rankings, and is now tied with the entire world combined at 58.

Tom Scott – The Aรฉroplume

An evening pause: This looks like an incredibly fun thing to do. From the youtube page:

The Aรฉroplume, in France, is a helium blimp sized for one person. โ‚ฌ60 gets you half an hour’s flight. I had to try it.

More information about buying a flight here.

Hat tip Jeff Poplin.

NASA releases new overall objectives for exploration of solar system

NASA today released a new roadmap for its goal of exploring the Moon, Mars, and the rest of the solar system, with the goal of providing an overarching strategy for everything it hopes to accomplish.

The resulting revised 63 final objectives reflect a matured strategy for NASA and its partners to develop a blueprint for sustained human presence and exploration throughout the solar system. They cover four broad areas: science; transportation and habitation; lunar and Martian infrastructure; and operations. The agency also added a set of recurring tenets to address common themes across objectives.

You can read the full document here [pdf].

The most astonishing thing about this roadmap is its utter lack of any mention of race or gender, especially when one considers how obsessed the Biden administration and its minions in federal bureaucracy have been over such things. The goals are entirely focused on exactly what they should be focused on, exploration and research, with the goal of partnering with as many private and governmental entities as possible to get it done in the most efficient way.

Researchers develop strongest-yet 3D printed titanium

Capitalism in space: Researchers at Monash University in Australia have successfully developed a 3D printed titanium alloy that has an internal strength exceeding that of normal commercially produced titanium.

In tests, the team demonstrated that the new titanium alloy had both elongation and tensile strengths (stretching and tension, respectively) of over 1,600 MPa. For reference, most commercial titanium alloys top out at around 1,000 MPa. This is also the highest specific strength for any other 3D-printed metal alloy, the team says.

Since 3D printing is going to be the main industrial manufacturing process in space, this process and the titanium it produces is certainly going to looked at with great interest by those who wish to build things in space. Imagine having a 3D printer that can make strong titanium parts in almost any needed shape. The possibilities are endless.
