Are Chang’e-6’s lunar samples on the way back to Earth?

9:30 am

In Friday’s June 21, 2024 quick links, changes to lunar orbit of China’s Chang’e-6 sample return spacecraft were detected by ham operators. As I noted, “It isn’t clear whether this was the previous orbit adjustment, a new one, or the burn that would send the sample return capsule back to Earth.”

According to Space News today, the spacecraft with the samples is on its way back to Earth, based on additional information detected by amateurs. China however has released no information on the status of the spacecraft.

Upon return to Earth, the reentry capsule is expected to touch down at Siziwang Banner, Inner Mongolia during an half-an-hour long window opening at 1:41 a.m. Eastern (0541 UTC) June 25. The information is according to airspace closure notices. CNSA has not openly published timings of mission events in advance.

Earlier reports (which I can’t find now) had said the return was tentatively scheduled for June 25, 2024, so this Space News report makes sense. The lack of information from China is par for the course.

France’s CNES space agency begins work adapting commercial launchpad at French Guiana for specific startup rocket companies

9:15 am

Capitalism in space: France’s CNES space agency, which has taken back ownership of its French Guiana spaceport from Arianespace, has now begun adapting its new commercial launchpad there for a number of specific startup rocket companies.

In early 2021, the French space agency CNES announced plans to open up the Guiana Space Centre to commercial micro and mini-launch operators. The agency explained that it would be developing a multi-user launch pad on the grounds of the old Diamant launch complex. In July 2022, CNES announced that it had pre-selected Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude to utilize the new launch complex.

During a media briefing following ESA’s 327th council meeting, Tolker-Nielsen explained that “general work” on the complex had already started and that work on “specific adaptations” was about to begin. These specific adaptations will be completed by the companies that will utilize the launch complex to ensure it fulfills the specific needs of their launch systems.

Of the seven rocket startups listed above, Tolker-Nielson said PLD was the ahead of the others in adapting the pad for its use, though no launch date is set. Avio meanwhile will likely not have to use this pad, as it owns the Vega family of rockets, which have already launched from French Guiana using another launchpad.

China’s successfully completes full 10K hop of 3-engine launch test rocket

8:57 am

China’s yesterday successfully completed a 10K hop lasting six minutes of 3-engine launch test small-scale rocket, lifting off from its Jiuquan spaceport in northwest China.

Developed by the Shanghai Academy of Spaceflight Technology, the carrier rocket features a 3.8-meter diameter rocket body, powered by three 70-tonne LOX/Methane engines and equipped with a full-size landing buffer system.

The rocket achieved vertical soft landing at a fixed point through take-off, ascent and variable-thrust descent. The test fully verified the rocket’s VTOL configuration, heavy-load landing buffer technology, reusable propulsion technology with high and strong variable thrust, and high-precision landing navigation and control technology.

I have embedded below a video that shows the take-off, parts of the flight, and landing. China hopes to fly a full scale orbital version, with a 4-meter diameter, in 2025.

Spacewalk on ISS canceled due to spacesuit issue

8:48 am

Two astronauts on ISS were forced today to abort their spacewalk soon after opening the hatch to go outside because a water issue in one suit.

This is the second time this spacewalk has been aborted. The first time, on June 13, 2024, was canceled due to an unspecified “spacesuit discomfort issue.”

This cancellation might cause a problem with the presently unscheduled return of Starliner, as its June 26, 2024 return was postponed to allow this spacewalk to take place without any schedule conflicts. Or it might simplify Starliner’s return, as the spacewalk will not happen due to spacesuit issues.

Note also that the American suits are old, and prone to these kinds of water leak issues. NASA started a project to replace them fifteen years ago, spent more than a billion on designs, getting nothing built, before abandoning its effort and awarding the project to two private companies.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

India’s prototype X-37B, dubbed Pushpak, completes third successfully drop test runway landing

10:43 pm

India’s space agency ISRO today successfully completed the third drop test from a helicopter to a runway landing of an X-37B engineering test vehicle, dubbed Pushpak.

The winged vehicle, named ‘Pushpak’, was released from an Indian Air Force Chinook Helicopter at an altitude of 4.5 km. Pushpak autonomously executed cross-range correction manoeuvres, approached the runway, and performed a precise horizontal landing at the runway centerline.

The vehicle also used the same body and flight systems from the previous flight without modifications. Though this is hardly a return from space, the landing profile attempted to duplicate much of that flight path, and thus demonstrated ISRO engineers are on the right track for creating a reusable mini-shuttle.

SpaceX completes two launches today, from opposite coasts

10:37 pm

The bunny marches on! SpaceX successfully completed two launches today.

First, its Falcon 9 rocket launched 22 Starlink satellites from Cape Canaveral in Florida. This was the launch that had been delayed several times by weather, and then by a tecnical launch abort at T-0. After several days of review, it lifted in the morning today with no problems, the first stage completing its eleventh flight, landing on a drone ship in the Atlantic.

Then, about ten hours later a Falcon 9 rocket lifted off in the evening Vandenberg in California, putting 20 Starlink satellites into orbit, 13 of which are said to be designed for direct cell-to-satellite capabilities. This first stage also completed its eleventh flight, landing on a drone ship in the Pacific.

This post is a bit late because we had a five hour power outage in my neighborhood tonight, caused apparently when someone drove into a utility pole and knocked it over.

The leaders in the 2024 launch race:

66 SpaceX
28 China
8 Russia
8 Rocket Lab

American private enterprise now leads the world combined in successful launches, 77 to 42, while SpaceX by itself still leads the entire world, including other American companies, 66 to 53.

China launches gamma-ray space telescope

9:50 am

China today successfully launched the Space-based Multi-band Variable Object Monitor (SVOM) gamma-ray space telescope, a 20-year-long joint Chinese-French project to monitor astronomical gamma ray bursts.

SVOM was placed in orbit by a Long March 2C rocket lifting off from China’s Xichang spaceport in the southwest of China. No word on where the rocket’s lower stages — which use very toxic hypergolic fuels — crashed inside China. UPDATE: See this video from China. Apparently one stage landed close to homes, spewing that orange hypergolic fuel.

The leaders in the 2024 launch race:

64 SpaceX
28 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 75 to 42, while SpaceX by itself still leads the entire world, including other American companies, 64 to 53.

Starliner return delayed again, until July

10:08 pm

NASA tonight announced that it is once again delaying the undocking from ISS and the return to Earth of Boeing’s Starliner capsule, carrying two astronauts, with the return date a as-yet unspecified date in July.

The move off Wednesday, June 26, deconflicts Starliner’s undocking and landing from a series of planned International Space Station spacewalks while allowing mission teams time to review propulsion system data.

It seems to me that they have decided the more time Starliner spends in space right now, the more data they can gather about its flightworthiness in the future. Remember, the first manned Dragon demo mission stayed at ISS for more than two months.

Their approach however — announcing small delays over and over again — is extremely poor PR. It makes it seem as if the capsule’s various issues — thrusters, helium leaks, and valves — are a more serious than I think they are.

Family whose home was damaged by NASA battery ejected from ISS files claim

3:29 pm

The Florida family whose home was damaged when a battery that NASA had ejected from ISS smashed through the roof of its house has now filed an $80,000 claim with the space agency.

Alejandro Otero, owner of the Naples, Florida, home struck by the debris, was not home when part of a battery pack from the International Space Station crashed through his home on March 8. His son Daniel, 19, was home but escaped injury. NASA has confirmed the 1.6-pound object, made of the metal alloy Inconel, was part of a battery pack jettisoned from the space station in 2021.

An attorney for the Otero family, Mica Nguyen Worthy, told Ars that she has asked NASA for “in excess of $80,000” for non-insured property damage loss, business interruption damages, emotional and mental anguish damages, and the costs for assistance from third parties. “We intentionally kept it very reasonable because we did not want it to appear to NASA that my clients are seeking a windfall,” Worthy said.

No lawsuit has been filed so far, as the family is trying to work this out with NASA amicably, and also help set a precedent for future such incidents. NASA in turn gave the family a claim form and is now reviewing the form they submitted.

The article I think is incorrect when it states that this incident “falls outside the Space Liability Convention” (which was written under the Outer Space Treaty) because the debris didn’t come from a foreign country but was launched and de-orbited by an American government agency. The Outer Space Treaty makes whoever launches anything in space liable for any damages. If NASA attempts to fight this it will be violating not only the language but the spirit of the treaty.
