Astra gets contract to provide engines to OneWeb satellites

8:59 am

Capitalism in space: Astra, the startup rocket company that recently announced a cessation in launches, has won a contract to provide engines used by OneWeb satellites to maneuver in orbit.

he Astra Spacecraft Engine was designed by Apollo Fusion, which Astra acquired last year. It is an electric Hall engine and has been used by York Space Systems, Spaceflight’s Orbital Transfer Vehicle (OTV) Sherpa-LTE, and a U.S. Air Force intelligence satellite. Astra signed a deal earlier this year to supply the engines to LeoStella.

In retrospect, the purchase by Astra of Apollo last year was a signal that the company might be shifting its gears away from rocketry, at least in the short term. This contract, along with the others won by Apollo before Astra bought it, provides Astra a survival profit stream even as it has leaves the rocket launch market while attempting to develop its proposed larger Rocket-4. Whether it can resume launches eventually remains somewhat doubtful, as a number of new rocket companies should become operational in the interim, making that smallsat launch market very crowded.

As I’ve said numerous times, I’ll believe this engine is a flight engine when I see it in flight.

The link goes to the research paper from the Beijing Institute of Space Mechanics and Electricity, which is in Chinese except for the abstract. This tweet highlights the “leg deploying test and full-scale landing impact experiment” from that paper.

SpaceX launches 54 Starlink satellites into orbit

8:52 pm

Capitalism in space: SpaceX tonight used its Falcon 9 rocket to put another 54 Starlink satellites into orbit.

The flight’s fairings completed their third flight. The first stage successfully completed its second flight, landing on a drone ship in the Atlantic. That stage however had an interesting first flight:

Known as B1069, the booster was damaged during recovery on a drone ship Dec. 21 after launching its first mission, sending a Dragon cargo ship toward the International Space Station. The rough recovery damaged the rocket’s engines and landing legs, causing the rocket to return aboard the drone ship to Port Canaveral on a tilt. The damage forced SpaceX and NASA to switch to a backup Falcon 9 booster for the launch of four astronauts to the space station in April. That launch was originally supposed to use B1069, which has been refurbished with new engines and other components.

In the past, rocket companies and NASA would have automatically thrown out this stage after being damaged. SpaceX however now treats these first stages like airplanes, repairable for reflight, even if damaged. Tonight’s flight proved the robustness of this strategy, and it did it carrying the most mass of any previous Falcon 9 launch.

The leaders in 2022 launch race:

38 SpaceX
33 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise now leads China 53 to 33, and the entire world combined 53 to 51.

Federal court rejects lawsuit by Dish/Viasat against Starlink

9:11 am

A U.S. appeals court has rejected a lawsuit by Starlink competitors Dish and Viasat that had claimed a plan by SpaceX to deploy some satellites in a lower orbit would have “potential environmental harms when satellites are taken out of orbit; light pollution that alters the night sky; orbital debris; collision risks that may affect Viasat; and because ‘Viasat will suffer unwarranted competitive injury.'”

This decision was the second time the courts have rejected this lawsuit, which by Viasat’s own words above is expressly designed mostly to block a competitor, not protect the environment or reduce space junk.

Starliner manned launch delayed until 2023

8:42 am

NASA and Boeing yesterday announced that the first manned flight of a Starliner capsule has been delayed again, and will not occur before February 2023, at the earliest.

This delay is in order to fix the various thruster problems that occurred in the second unmanned demo flight in May 2021, dubbed OFT-2.

Nappi said some “debris-related conditions” likely caused those thrusters to shut down, but later noted that is their best estimate since the OMAC thrusters are in a service module that burns up on reentry and is not recovered. “We do not know where the debris may have come from,” he said. “The bottom line is that it looks to be the leading root cause, and we’ve eliminated that by looking at the CFT vehicle and making sure that there’s absolutely no debris in the system.”

Several reaction control thrusters also shut down during the mission, which Nappi said was likely due to low inlet pressures and can be addressed with a “tweak in timing and tolerances” in software. High pressures in a thermal control loop noticed in the mission were linked to filters that engineers determined are not needed and can be removed. A guidance system on the spacecraft called VESTA worked well but generated more data than the flight software could handle, requiring changes to the software. [emphasis mine]

The highlighted words indicate once again that there are quality control problems at Boeing. For any “debris” to get into the thrusters without notice means someone at some point wasn’t doing things right.

SpaceX and Boeing got contracts to fly humans on their commercial capsules at the same time, in 2014. SpaceX began those flights in 2020, about three years behind schedule, mostly due to NASA-imposed delays. Boeing has still not flown, with almost all its delays resulting from company failures, almost all of which were uncovered during the two unmanned demo flights in 2019 and 2022.

Hopefully, the company will finally get the last kinks from the system before next year’s flight. In the meantime its inability to get this job done on time has meant it has lost a lot of commercial business, all of which went to SpaceX.

T-Mobile and Starlink to team up

9:10 pm

SpaceX and T-Mobile today announced that sometime next year T-Mobile cell phones will use the Starlink satellite constellation to fill in any dead zones in its cell coverage.

T-Mobile says it’s getting rid of mobile dead zones thanks to a new partnership with SpaceX’s Starlink satellite internet, at an event hosted by T-Mobile CEO Mike Sievert and Elon Musk. With their “Coverage Above and Beyond” setup, mobile phones could connect to satellites and use a slice of a connection providing around 2 to 4 Megabits per second connection (total) across a given coverage area.

That connection should be enough to let you text, send MMS messages, and even use “select messaging apps” whenever you have a clear view of the sky, even if there’s no traditional service available. According to a press release from T-Mobile, the “satellite-to-cellular service” will be available “everywhere in the continental US, Hawaii, parts of Alaska, Puerto Rico and territorial waters.” The service is scheduled to launch in beta by the end of next year in “select areas,” and Sievert says he hopes it will someday include data.

The system will require Starlink’s second generation satellites, which right now also require SpaceX’s big Starship for launch. Once operational however it will work on the cell phones customers already own.

Fred Astaire & Ginger Rogers – Never Gonna Dance

6:01 pm

An evening pause: We’ve had a lot of 1970s pop songs and dance recently. Here’s an example of one of the greatest movie dance numbers, from the 1936 movie Swing Time. Note how smooth and ballet-like it is, unlike the staccato and gymnastic styles that began to dominate dance after the 1960s.

Note also the remarkable lack of cuts. The dance is performed with only one cut, which means Astaire and Rogers had to get it perfect, the whole way through each of these two shots. It took 47 takes before they succeeded.

SpaceX remounts Superheavy prototype #7 on launchpad

11:05 am

Superheavy #7 lifted onto launchpad

Capitalism in space: Using its giant launch tower crane that Elon Musk has dubbed Mechazilla, SpaceX engineers yesterday remounted the seventh Superheavy prototype onto the orbital launchpad in preparation for more engine tests leading to its first flight.

Booster 7 has been atop this launch mount before. Earlier this month, SpaceX conducted two “static fire” tests with Booster 7, firing the vehicle up while it remained attached to the mount.

Both of those tests — which occurred on Aug. 9 and Aug. 11, respectively — lit up just a single Raptor engine (apparently, a different one each time). And Booster 7 wasn’t fully outfitted at the time, sporting just 20 of its 33 engines (opens in new tab) (the vast majority of which stayed dormant during the tests).

After the Aug. 11 test, SpaceX lifted the Super Heavy prototype off the mount and hauled it back to a processing bay at Starbase. Technicians installed the remaining 13 Raptors and got it ready for Tuesday’s move back to the pad.

The picture above was sent out by Musk on his Twitter feed. Note the number of engines at the base. The tower itself, acting as a crane, has also simplified and speeded up operations. SpaceX can now quickly move the rocket back and forth from the assembly building, without the need of separate cranes.

The company is still targeting early September for the first orbital launch, though it also still needs to stack Starship prototype #24 (seen in the background) on top of Superheavy, and then do more tests.

NASA describes Starship’s first unmanned test lunar landing

9:28 am

In a briefing focused on the science that could be placed on the mission, a NASA official yesterday provided a status update of SpaceX’s first unmanned test flight by Starship to the Moon.

First, the official revealed that NASA is only requiring SpaceX to demonstrate a successful landing. Take-off will not be required. Also,

Starship is not designed to fly directly to the Moon like NASA’s Space Launch System, however. Instead, the first stage puts it only in Earth orbit. To go further, it must fill up with propellant at a yet-to-be-built orbiting fuel depot. Other Starships are needed to deliver propellant to the depot.

Watson-Morgan described the Concept of Operations for Starship’s Artemis III mission, starting with launch of the fuel depot, then a number of “propellant aggregation” launches to fill up the depot, then launch of the Starship that will go to Moon.

Previously SpaceX suggested that the ship would be directly refueled by subsequent Starships, with no middle-man fueling depot. It could be either engineering had made the depot necessary, or NASA politics have insisted upon it.

Finally, the talk outlined the elevator SpaceX is developing to lower the astronauts and equipment to the ground from Starship’s top.

SpaceX to use both Falcon 9 and Starship to launch 2nd gen Starlink satellites

9:06 am

Capitalism in space: In a letter sent to the FCC, SpaceX has revealed that it has revised its plans for launching the second generation of Starlink satellites, and has decided to launch them with both Falcon 9 and Starship rockets.

SpaceX has decided to use a mix of Falcon 9 and Starship rockets to launch the 30,000 satellites in its proposed second-generation Starlink broadband constellation. Launching some of the satellites with SpaceX’s “tested and dependable Falcon 9” will accelerate the constellation’s deployment to improve Starlink services. SpaceX director of satellite policy David Goldman wrote in an Aug. 19 letter to the Federal Communications Commission. Goldman did not say when SpaceX could start launching the second-generation constellation, which remains subject to FCC approval.

Previously the company’s plan had been to use Starship only, essentially retiring Falcon 9 once Starship was flying. This change could be for two fundamental reasons. First, the company has been launching Starlinks on Falcon 9 like clockwork this year, at a pace that could launch as many as 2,500 Starlink satellites in 2022 alone. With about 70% of that rocket reusable, it might now seem cost effective to continue to use it, even after Starship is flying.

The second reason is more worrisome, and has to do with Starship itself. SpaceX officials might now realize that the delays being imposed by the federal regulatory leviathan on Starship development might be significant enough that it won’t be ready when they need it for the full deployment of Starlink’s second generation constellation. If the FCC approves that deployment (an approval that is presently pending), SpaceX will have to launch at least half the full constellation of 30,000 satellites by around 2024 (thought that date might have been revised slightly).

It now might be necessary to use Falcon 9, because the federal government under Biden is standing in the way of Starship development.

Of course, it is possible that the engineering challenge of building Starship might be another reason. SpaceX might have realized that the rocket will be delayed anyway, and thus needs Falcon 9 to meet its timetable as promised to the FCC.

NASA again approves design concept for Orbital Reef commercial space station

10:53 am

Proposed Orbital Reef space station

Capitalism in space: Sierra Space announced today that NASA has completed, apparently for the second time, the design review for the Orbital Reef space station that the company wants to build in partnership with Blue Origin and others, thus allowing the actual design of the station to begin.

This press release announcement, on August 22, 2022, is a bit puzzling, as Sierra Space made almost the exact same announcement in April 2022. What, did NASA have to do this twice? Did issues come up after the first approval? Was the agency reviewing different things?

Regardless, NASA as usual is slowing things down considerably. Sierra Space and Blue Origin, the primary partners in this private space station project, first announced it in October 2021. It took the government almost a year to simply approve the basic concept so that the design phase could finally begin. At this pace it will be 2090 before the station is launched.

SpaceX and China complete launches

12:51 pm

Two launches have just occurred in the 2022 launch race. First, SpaceX today successfully launched another 53 Starlink satellites, using its Falcon 9 rocket.

The first stage successfully landed on its drone ship in the Atlantic, completing its ninth flight.

China in turn used its Long March 2D rocket to launch three military reconnaissance satellites, at what was the early morning hours of August 20, 2022, China time. The launch path took the rocket over China’s interior as well as Taiwan, with the first stage crashing somewhere in China.

The leaders in the 2022 launch race:

37 SpaceX
31 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 52 to 31 in the national rankings, and the entire world 52 to 49. The 52 launches so far this year is now the fifth best total for the U.S. since the launch of Sputnik in 1957.
