ABL completes static fire test of first stage of its new RS1 rocket

9:06 am

Capitalism in space: The new smallsat rocket startup ABL has successfully completed a full static fire test of the first stage of its new RS1 rocket from its launchpad in Kodiak, Alaska.

Company executives said that they performed the static-fire test of the first stage of its RS1 rocket July 9 at the Pacific Spaceport Complex – Alaska on Kodiak Island, the site where the company plans to conduct its first launch.

“The operation verified our startup sequence and stage level engine performance,” Harry O’Hanley, chief executive of ABL, said in a statement to SpaceNews. “A testament to our team’s intense preparation, we completed the test on the first attempt.”

The static-fire test also verified the performance of the ground systems, including a portable launch stool that can be packed into a shipping container. That system, O’Hanley said, enables launching from a flat pad like at Kodiak.

The company is presently completing testing of the rocket’s upper stage, with its next task to mate the two and complete a full dress rehearsal countdown. Though no launch date has been set, the company has been targeting a launch before the end of this year.

OneWeb agrees with SpaceX: Dish’s ground-based plans a frequency threat

9:01 am

Capitalism in space: In a filing with the FCC, OneWeb has come out in full agreement with its competitor SpaceX, stating that Dish’s proposal to use the 12 GHz wavelength would threaten its satellite communications.

In a letter to the Federal Communications Commission, OneWeb urged the regulator to reject a request from satellite broadcaster Dish Network and spectrum holder RS Access to run two-way mobile services in the band. If approved, “it would leave significant areas of the United States unusable by the otherwise ubiquitous NGSO [fixed satellite service] user terminals,” wrote Kimberly Baum, OneWeb’s vice president of spectrum engineering and strategy.

To connect user terminals, the SpaceX-owned Starlink and OneWeb megaconstellations use a satellite downlink band that extends from 10.7 GHz to 12.7 GHz. The analysis from OneWeb is the latest in a string of studies assessing how a high-power mobile network in the 12.2-12.7 GHz band would impact NGSO services.

Though the FCC has not yet made a final decision, it has already rejected Dish network’s request to block SpaceX’s use with Starlink of these wavelengths.

Superheavy prototype #7 explodes during tanking test

8:37 am

Capitalism in space: SpaceX’s Superheavy prototype #7 exploded yesterday during a tanking test in Boca Chica, Texas.

I have embedded the video of the explosion below, cued to just before it occurred.

According to Musk, the engineering teams are presently assessing damage. The booster itself appeared relatively intact afterward, though leaning slightly to one side.

At a minimum this incident will delay the orbital launch attempt, especially if booster #7 must be replaced with booster #8, already being prepped in the assembly building nearby.

SpaceX launches another 46 Starlink satellites

6:49 pm

Capitalism in space: Using its Falcon 9 rocket, SpaceX today successfully launched another 46 Starlink satellites from Vandenberg Space Force Base in California.

The first stage completed its sixth flight, landing on the drone ship in the Pacific.

A minor note: SpaceX has clearly decided to simplify these broadcasts. Each is now starting much closer to launch, and the announcers have reduced their narration to the absolute minimum. Overall, this seems a wise policy, because though these live streams are good advertising, most of the people listening at this point do not need detailed explanations of everything. If anything, too much chatter is annoying, and as always less is more.

The leaders in the 2022 launch race:

29 SpaceX
21 China
9 Russia
4 Rocket Lab
4 ULA

The U.S. now leads China 41 to 21 in the national rankings, and the entire world combined 41 to 36. The forty-one launches in just over half of ’22 beats the U.S.’s total for the whole year just two years ago.

Elon Musk gives a tutorial on the Raptor-2 engine

6:16 pm

Tim Dodd of Everyday Astronaut on Friday released another video from his most recent tour of Starbase at Boca Chica with Elon Musk. I have embedded it below.

Essentially, this 41 minute video is Elon Musk giving us a tutorial on how SpaceX simplified and improved its Raptor engines from its first iteration to the present Raptor-2. He does this while standing in front of a long row of finished Raptor-2s, all meant for installation in the seventh prototype of Superheavy, the booster now on the launchpad with those engines installed and being prepared for its first static fire test prior to the orbital flight.

Musk revealed two interesting factoids during this video. First SpaceX blew up approximately 20 to 30 Raptor engines during the development phase, and melted the chambers on another 50. All of this was perfectly acceptable, because they designed engine manufacture so that a high production rate was built in. As Musk noted, “A high production rate solves many ills.” Losing engines during testing and development was no big deal because they were able to quickly replace them, with revisions and upgrades.

Secondly, Musk claimed that the Raptor-2 engine has a 99% efficiency, a level of efficiency that is unheard of in any engine for any purpose ever. I wonder if that claim will hold up as new companies and engineers work to beat SpaceX in the coming centuries.

Dish Network condemns Starlink and SpaceX study

9:42 am

Constellation wars! In an apparent response to the FCC’s decision last week to reject the Dish network’s request that the agency block Starlink from using the 12GHz frequency band so that Dish could use it, Dish (as part of a coalition) now claims that SpaceX’s study on the use of that band is “scientifically and logically flawed” and used “cherry-picked” data.

While the FCC had rejected Dish’s blocking request, it also said it was still studying whether Starlink’s orbital system and Dish’s ground-based system could both use the frequency at the same time. Today’s statement is obviously Dish’s effort to influence that FCC study.

The coalition’s full statement also said this about the request by Starlink to its customers to send their own comments to the FCC:

In addition to this manipulated filing, Starlink has initiated a public misinformation campaign by falsely telling customers and the public that coexistence is not possible in the band among Starlink and 5G services – despite nationwide data proving otherwise. This tactic, which is commonly used by Elon Musk, is not only disingenuous, but it promulgates an anti-5G narrative that is harmful to American consumers who deserve greater competition, connectivity options and innovation. It also stands to threaten America’s global leadership in the 5G and technology sector as other countries outpace the nation in delivering next-generation services.

This constellation war has hardly begun. Expect politicians to soon get involved, both pro and con, prompted by campaign contributions from the commercial players (which when paid to ordinary we call it “bribes”).

Meanwhile, SpaceX announced yesterday that Starlink is now offering its service to boat owners, though the service is hardly cheap.

Starlink Maritime costs $5,000 per month, plus an initial $10,000 fee that covers two high-performance satellite dishes. It promises to deliver download speeds of 350 Mbps. Regular Starlink internet costs $110 per month, along with $599 for the necessary hardware.

Virgin Galactic is replacing its WhiteKnightTwo mother ship

9:21 am

Virgin Galactic yesterday announced that it has hired Aurora, a Boeing subsidiary, to build two new mother ships to to replace WhiteKnightTwo and launch its SpaceShipTwo suborbital space planes.

Virgin Galactic Chief Executive Officer Michael Colglazier said: “Our next generation motherships are integral to scaling our operations. They will be faster to produce, easier to maintain and will allow us to fly substantially more missions each year. Supported by the scale and strength of Boeing, Aurora is the ideal manufacturing partner for us as we build our fleet to support 400 flights per year at Spaceport America.” [emphasis mine]

The press release claims the first new mother ship will begin operations in 2025.

Forgive me if I am very very skeptical. The highlighted words tell us a lot about this company. First, we now have confirmation that the company has had problems maintaining WhiteKnightTwo. This fact was strongly implied when all planned flights in ’21 and ’22 were cancelled following that first passenger flight in July ’21 in order to do a full maintenance refit of WhiteKnightTwo. This press release tells us that the company’s management has recognized that WhiteKnightTwo cannot be maintained much longer.

Second, the company continues to overhype its future, even without Richard Branson. The chances of it flying 400 times per year, anytime in the near future, is so slim as to be non-existent.

Third, the need to hire an outside company to build these new mother ships also suggests that Virgin Galactic no longer has the capability of doing it itself.

Right now the company’s stock is selling for about $7 per share, well below its initial price of about $12. Expect it to fall again.

SpaceX launches another 53 Starlink satellites

8:38 am

Capitalism in space: Earlier this morning SpaceX successfully launched 53 Starlink satellites, using its Falcon 9 rocket.

The first stage was flying its thirteenth flight, and supposedly landed successfully, though the stage’s video cut off just before landing, the drone ship video did not show it on the pad, and the confirmation of that landing was very late. It is possible it landed on a spot that the camera did not show, or that the landing occurred in the ocean and the stage was lost. We shall have to wait and see.

The leaders in the 2022 launch race:

28 SpaceX
21 China
8 Russia
4 Rocket Lab
4 ULA

The U.S. now leads China 40 to 21 in the national rankings, and the entire world combined 40 to 35.

Having regained communications with CAPSTONE, engineers prepare for first mid-course burn

8:55 pm

Engineers are now preparing CAPSTONE for its first first mid-course engine burn, slightly late due to a loss of communications during the past two days.

The spacecraft is in good health and functioning properly.

The CAPSTONE team is still actively working to fully establish the root cause of the issue. Ground-based testing suggests the issue was triggered during commissioning activities of the communications system. The team will continue to evaluate the data leading up to the communications issue and monitor CAPSTONE’s status.

If all goes well, that engine burn will occur as early as 11:30 am (Eastern) on July 7th.

Rocket Lab to launch twice in 10 days for NRO

9:11 am

Capitalism in space: Rocket Lab announced yesterday that its next two launches, scheduled for July 12th and July 22nd, will demonstrate the ability of the company to quickly launch reconnaissance satellites for the National Reconnaissance Office (NRO).

The NROL-162 and NROL-199 missions will carry national security payloads designed, built, and operated by the National Reconnaissance Office in partnership with the Australian Department of Defence as part of a broad range of cooperative satellite activities with Australia. The satellites will support the NRO to provide critical information to government agencies and decision makers monitoring international issues.

These twin missions will be a demonstration of responsive launch under NRO’s Rapid Acquisition of a Small Rocket (RASR) contract for launching small satellite through a streamlined, commercial approach, and are the third and fourth missions contracted to Rocket Lab by the NRO under the contract.

Several federal military agencies have been testing this capability with almost all the new rocket companies, from the large, such as SpaceX, to the small, such as Rocket Lab and Astra.

Engineers lose contact with CAPSTONE on its way to Moon

2:24 pm

Shortly after the spacecraft was successfully deployed from its Proton upper stage on yesterday, engineers lost contact with the spacecraft as it headed towards the Moon.

“The spacecraft team currently is working to understand the cause and re-establish contact. The team has good trajectory data for the spacecraft based on the first full and second partial ground station pass with the Deep Space Network,” NASA spokesperson Sarah Frazier wrote in an emailed statement today (July 5).

“If needed, the mission has enough fuel to delay the initial post-separation trajectory correction maneuver for several days,” Frazier added. “Additional updates will be provided as soon as possible.”

The spacecraft will not arrive in lunar orbit until November, but along the way it needs to do a number of course corrections. Thus, there is some time pressure to reestablishing communications. That task now falls with the private company Advanced Space, which won a contract to operate the spacecraft for NASA.

UPDATE: More details are provided by the operators of the spacecraft, Advanced Space press, here. Though they canceled a course correction burn today, they apparently have plenty of time to do it, since the probe is already on a course to reach lunar orbit. The burn was simply intended to increase the accuracy of the trajectory.
