ESA awards D-Orbit €119.6 million contract to complete Europe’s first robotic service mission

9:25 am

The European Space Agency (ESA) today awarded the European orbital tug company D-Orbit a €119.6 million contract to fly Europe’s first robotic mission to extend the life of an already orbiting satellite.

Referred to as RISE, the mission will demonstrate the D-Orbit GEA satellite life extension vehicle’s ability to dock with a geostationary satellite, maneuver the satellite, and then release it. After this sequence is verified, ESA’s involvement in its operation will come to an end. The vehicle will then move into an operational phase with D-Orbit offering a life extension service to active geostationary satellite operators.

The mission is targeting a 2028 launch, though no specific target satellite as yet has been identified.

This project is very similar to the Mission Extension Vehicle (MEV) robotic missions of Northrop Grumman, which has been flown twice successfully. I guess ESA needed to see it work before it would consider doing its own mission. Moreover, ESA probably wanted to sign up a European company to do it, and until now no such company existed. D-Orbit has already completed fourteen orbital tug missions with seven more scheduled for 2025. This mission extension project however will be a significant leap forward in its capabilities, funded by ESA.

Musk says SpaceX will sue California Coastal Commission

8:42 am

In a tweet on X on October 12, 2024, Elon Musk said that SpaceX will sue the California Coastal Commission for violating his first amendment rights as soon the court opens tomorrow.

“Filing suit against them on Monday for violating the First Amendment,” he wrote, adding: “Tuesday, since court is closed on Monday.”

At least two commissioners had made it very clear in public statements at a hearing last week that they were voting against a Space Force request that would increase the number of launches at Vandenberg because they opposed Elon Musk’s political positions, not because the request would do any harm to the coast. The commission then rejected the request 6-4, with others claiming that SpaceX should have made the request directly rather than have the Space Force do it.

The vote remains non-binding, as the Space Force has the legal power to do whatever it wants at Vandenberg, and only works with the commission as a courtesy.

SpaceX Starship/Superheavy test flight achieves 100% of its goals

6:53 am

In SpaceX’s fifth orbital test flight of its Starship/Superheavy rocket, the company astonishingly achieved 100% of its goals, with Superheavy successfully returning to the launch tower and caught by the tower chopsticks on the very first attempt, and Starship successfully completing a soft splashdown in the Indian Ocean, hitting its target landing spot for the first time.

The full video of the live stream is embedded below.

The capture of Superheavy, as shown in the screen capture to the right, was especially incredible. The first attempts to vertically soft land the first stage of the Falcon 9 back in the mid-2010s were not unprecedented, the concept of which had previously been demonstrated by numerous tests on Earth as well as the Apollo landings. The tower chopstick capture of Superheavy was an entirely new concept and had never even been tested previously, anywhere, by anyone. To hit the mark and succeed on the first attempt is mind-boggling. The reaction of the SpaceX employees illustrated this, as they were overwhelmed by their own success.

As for Starship, like the fourth test flight there was some burn through damage seen on at least one of the control flaps, but much less this time. Moreover, the spacecraft was under full control during its entire flight, followed its planned flight plan, and landed on its target in the Indian Ocean.

With that success, I predict SpaceX will do a full orbit of Starship on the next test flight, #6, and attempt to land Starship vertically on land, possibly at Boca Chica or elsewhere. To do this will of course require government approvals, something that will likely slow things down again while accomplishing nothing, because in the end the bureaucrats will have to say yes anyway.

The leaders in the 2024 launch race:

97 SpaceX
45 China
11 Russia
11 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 114 to 68, while SpaceX by itself now leads the entire world, including American companies, 97 to 85.

FAA approves launch license for tomorrow’s SpaceX Starship/Superheavy launch

12:24 pm

The FAA today announced that it has finally approved a launch license for the fifth test launch tomorrow of SpaceX’s Starship/Superheavy, and that this approval applies to the next few launches as well, assuming the FAA or other government agencies or politicians don’t attempt to nitpick things again.

The full written re-evaluation [pdf] released today is somewhat hilarious, in that it spends 61 pages essentially concluding that SpaceX’s proposed actions were already approved by the 2022 Environoment Reassessment [abbreviated PEA by the FAA], spending page after page detailing why a license should be approved based on that 2022 reassessment. After wasting more than two months essentially retyping the 2022 conclusions, this report concludes ludicrously:

The 2022 PEA examined the potential for significant environmental impacts from Starship/SuperHeavy launch operations at the Boca Chica Launch Site and defined the regulatory setting for impacts associated with Starship/Super Heavy. The areas evaluated for environmental impacts in this WR [written reevaluation] included noise and noise compatible land use and biological resources.

Based on the above review and in conformity with FAA Order 1050.1F, Paragraph 9-2.c, the FAA has concluded that the modification of an existing vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, that the data contained in the 2022 PEA remains substantially valid, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action. Therefore, the preparation of a supplemental or new environmental document is not necessary to support the Proposed Action.

In plain English, SpaceX is doing nothing to require this bureaucratic paperwork, but we have insisted on doing it anyway in order to justify our useless jobs while acting to squelch free Americans from getting the job done as they wish. As Musk so rightly put it last month, “It takes longer to do the government paperwork to license a rocket launch than it does to design and build the actual hardware.”

Despite this approval, we must emphasize that this action has now set a very bad precedent for the future, When SpaceX makes changes to its flight plans on future test launches — something that is guaranteed as the company incrementally improves the design — the FAA will almost certainly shut things down again as it spends months once again determining that nothing is wrong.

Either way, stand by for tomorrow’s test launch, lifting off at 7 am (Central time). I have embedded the Space Affairs youtube live stream below, since SpaceX’s live streams on X don’t allow one to stand by, and will only go live 35 minutes before launch.

California officials: SpaceX shouldn’t be allowed to launch from Vandenberg because we hate Elon Musk

10:11 am

In voting yesterday to reject a plan by the military to increase the number of launches at Vandenberg Space Force Base in California, members of the California Coastal Commission admitted openly they did so because they do not like Elon Musk and his publicly stated political preferences.

The California Coastal Commission on Thursday rejected the Air Force’s plan to give SpaceX permission to launch up to 50 rockets a year from Vandenberg Air Force Base in Santa Barbara County.

“Elon Musk is hopping about the country, spewing and tweeting political falsehoods and attacking FEMA while claiming his desire to help the hurricane victims with free Starlink access to the internet,” Commissioner Gretchen Newsom said at the meeting in San Diego.

…“I really appreciate the work of the Space Force,” said Commission Chair Caryl Hart. “But here we’re dealing with a company, the head of which has aggressively injected himself into the presidential race and he’s managed a company in a way that was just described by Commissioner Newsom that I find to be very disturbing.”

It must be noted that this vote is not legally binding on the military. Though it has always tried to work in cooperation with this commission, it has the right to decide for itself how many launches it wants to allow out of Vandenberg. Whether it will defy the commission however is uncertain, and likely depends entirely on who wins the presidential election. If Harris wins, she will likely order the Space Force to not only obey the commission but to further limit launches by SpaceX at Vandenberg. If Trump wins, he will likely tell the Space Force to go ahead and expand operations, ignoring the immoral political machinations of these commissioners.

And it must be emphasized how immoral and improper these commissioners are. Their task is to regulate the use of the California coast in order to protect it for all future users, from beach-goers to rocket companies. It is not their right to block the coast’s use to certain individuals simply because those individuals have expressed political views they oppose. Not only does this violate Musk’s first amendment rights, it is an outright abuse of power.

If anyone in California reading this article wishes to tell these commissioners what they think of their actions yesterday, you can find their contact information here.

Fringe activists in Texas sue SpaceX to prevent further launches of Starship/Superheavy

9:50 am

In an obvious attempt to block SpaceX’s effort to do the fifth Starship/Superheavy orbital test launch this coming weekend, a fringe activist group dubbed Save RGV has now sued the company, accusing it of using industrial wastewater in the launchpad’s deluge system that acts to minimize damage to the pad.

The suit, filed Wednesday in U.S. District Court for the Southern District of Texas, Brownsville Division, under the Clean Water Act (CWA), seeks declaratory and injunctive relief, the imposition of civil penalties and “other appropriate relief” to bring a halt to SpaceX’s “recurring, unpermitted discharges of untreated industrial wastewater from the deluge system at the SpaceX Boca Chica Launch Site into waters of the United States,” according to the suit.

According to SpaceX, water in the deluge system is potable drinking water. Moreover, in previous launches the company obtained all the proper licenses for its use, only to have the EPA subsequently step in and claim SpaceX had “violated the Clean Water Act in deploying the deluge system. The EPA did not assess a fine, but did order SpaceX to comply with federal regulations.” That action has forced the FAA to delay issuing any further launch licenses, even as of today.

I call Save RGV a fringe group because it has almost no support from within the Rio Grande Valley surrounding Boca Chica and Brownsville. That community is overwhelming in support of SpaceX’s efforts, and wants it to grow and expand, because of all the jobs and money it is bringing to the region.

This suit is clearly an attempt to forestall any launch license approval the FAA might want to issue for SpaceX’s desire to launch this weekend, on October 13, 2024. SpaceX is ready to go that day, and is now merely waiting for the FAA to “go!”.

On-going manned test flights of Boom’s prototype supersonic plane inching towards the supersonic

9:28 am

During the on-going manned test flights of Boom’s one-third scale prototype supersonic plane, dubbed XB-1, the maximum flight speeds have been steadily increased as they company tests the plane’s design and structure.

[On October 7th on the fifth manned flight] Chief Test Pilot Tristan “Geppetto” Brandenburg set a record for the XB-1 shod with GE J85-15 turbojet engines, taking it up to 17,800 ft (5,425 m) and as fast as Mach 0.69 (428 knots / 492 mph / 791 km/h, true airspeed) over its 50-minute-long test flight, marking the highest and the fastest it’s flown so far.

Boom tested its flutter excitation system (FES) at Mach 0.6 … which must be unnerving for a test pilot. The FES is a system that deliberately induces vibrations into an aircraft’s airframe to help engineers find potential structural issues, particularly at higher speeds. They do this so structural issues (that could cause flutter) don’t rear their ugly head mid-flight.

The plan is to do five more test flights before attempted to break the sound barrier.

At the completion of this testing the company will then begin manufacture of its full scale supersonic passenger plane, dubbed Overture, that will carry up to 80 passengers and will sell to airlines. It already has contracts and financial support from a number of major airlines, including United and Japan Airlines.

Arianespace sets December 3, 2024 for the next Vega-C launch

9:17 am

Arianespace today announced that the next Vega-C launch is now scheduled for December 3, 2024, the first in more than two years since a launch failure in 2022.

The failure was caused by a design flaw in the rocket’s upper stage engine nozzle. In attempting to fix the problem, the first redesign failed as well during a static fire test in 2023. The second redesign has now passed all engine tests.

This launch — of a European Space Agency (ESA) radar satellite — is being managed by Arianespace, the commercial arm of ESA that is presently being phased out. Beginning late next year the rocket’s manufacturer, Avio, will regain complete control of its rocket and will be able to market it internationally, no longer required to deal with this unneeded government middleman. Expect the launch price to drop at that point to make Vega-C more competitive.

NATO to issue new space strategy to address growth in commercial sector

9:07 am

Capitalism in space? NATO officials at a meeting this week proposed issuing a new space strategy next year, designed to deal with the changing relationship in space between government and private enterprise.

During the Commercial Space Forum at NATO, participants discussed the threats they face, from cyber-attacks against ground systems, to jamming or spoofing of GPS and other satellite communications signals. They also addressed the importance of further investment in areas such as cybersecurity and sharing information about threats.

NATO Assistant Secretary General for Defence Investment, Ms Tarja Jaakkola, highlighted the need for a new relationship between the military and the commercial sector, “where both sides can learn from another, and where we can support and harness the entrepreneurial spirit and technological innovation essential to keep our defences strong and effective.”

More information here. It appears that NATO officials have realized that they can no longer do things as they have for the past half century, whereby they design, build, and own the space assets they launch. They must instead do what NASA and the Pentagon has been doing, become the customer that buys such products from the private enterprise.

Mitsuibishi’s H3 rocket wins launch contract from UAE

8:55 am

Capitalism in space: The United Arab Emirates (UAE) yesterday announced that it has awarded the launch contract for its first unmanned probe to the asteroid belt to the Japanese company Mitsuibishi and its new H3 rocket.

The UAE Space Agency (UAESA) announced Oct. 10 it selected Mitsubishi Heavy Industries to launch its Emirates Mission to the Asteroid Belt (EMA) on an H3 rocket in the first quarter of 2028. Terms of the contract were not disclosed.

The spacecraft, also known as MBR Explorer after Sheikh Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai, will fly by six main belt asteroids between 2030 and 2033 before rendezvousing on a seventh, Justitia, in 2034, later deploying a lander.

This mission is the third that the UAE has selected MHI to launch. An H-2A rocket launched the Emirates Mars Mission, a Mars orbiter, in 2020, while KhalifaSat, a remote sensing satellite, launched as a secondary payload on another H-2A in 2018.

What makes this launch contract different from the previous two is that the winner is Mitsubishi. Previous awards went through Japan’s space agency JAXA, which appeared to manage the H2A entirely. Now, Mitsubishi is in control, and is working directly with its customer.

This change proves that Japan’s government effort to promote private enterprise in space is real, that though it has been slow to wrest bureaucratic control from JAXA, that wresting is happening nonetheless.

The pimpled floor of Isidis Basin on Mars

The pimpled floor of Isidis Basin on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 21, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a “terrain sample,” it was likely taken not as part of any specific research project but chosen by the camera team to fill a gap in the camera’s schedule in order to maintain its proper temperature.

When they do this they try to pick a target that is somewhat interesting, though it is not always possible. In this case it appears they succeeded in capturing a location filled with lots of puzzling stuff, including low 60-to-80-foot-high mesas with either flat- or hollow-tops, shallow craters that appear almost buried, and other craters that appear so deep and shadowed that it is even possible these are skylights into underground caves.

In between these features the flat landscape has a scattering of ripple dunes, all oriented in the same direction and thus implying that the prevailing winds are or were blowing from the northeast to the southwest.

EPA to NASA: We intend to regulate how you dispose ISS, and that’s only the start

12:47 pm

The FAA to SpaceX
The EPA and its supporters to the American space industry:
“Nice industry you got here. Sure would be a shame if
something happened to it.”

It appears the Environmental Protection Agency (EPA) and a number of activist groups are now lobbying for the right to regulate whether anything in orbit can be de-orbited into the oceans, beginning with how NASA plans to dispose of the International Space Station (ISS) when the station is de-orbited into the ocean sometime before 2030.

The U.S. Environmental Protection Agency (EPA) is evaluating how the disposal of the International Space Station into the ocean will need to be regulated but has not shared the details of any specific concerns or aspects of regulation. “EPA’s Office of Water is coordinating with the Office of General Counsel on this complex issue. The agency does not have a timeline for this evaluation,” EPA spokeswoman Dominique Joseph told SpaceNews.

“Sixty-six years of space activities has resulted in tens of thousands of tons of space debris crashing into the oceans,” said Ewan Wright, a Ph.D. candidate at the University of British Columbia and a junior fellow of the Outer Space Institute, an interdisciplinary group of experts working on emerging space sustainability issues.

While Wright is later quoted as saying that disposal in the ocean is “the least worst option,” the article at the link includes quotes from several other academics, all claiming that such an option must be stopped at all costs, because it threatens to “cause great damage” to the ocean. These “experts” make this claim by comparing ISS’s de-orbit with the dumping of old ammunition from World War I as well as plastic forks now.
