The first stage completed its second flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

128 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 147 to 91, while SpaceX by itself leads the entire world, including American companies, 128 to 110.

Strange flat layers on Mars

12:47 pm

Strange layers on Mars

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on July 16, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what MRO’s camera team labels as “layers near ridge in Argyre Planitia.”

The layers are strange because there is so little topographic difference between them. Though the ground slopes downward from the south to the north, dropping about 1,300 feet, it does so almost smoothly. The layers show relatively little topographic relief.

And what caused the circular shape? Is it evidence of a buried crater? And if so, why so little relief at its rim?

As always, the overview map provides some answers.

Iran launches its Simorgh orbital rocket

11:11 am

Iran today announced it has successfully placed several small payloads into orbit, its Simorgh rocket lifting off from its interior Semnan spaceport.

The Simorgh carried what Iran described as an “orbital propulsion system,” as well as two research systems to a 400-kilometer (250-mile) orbit above the Earth. A system that could change the orbit of a spacecraft would allow Iran to geo-synchronize the orbits of its satellites, a capability Tehran has long sought.

It also carried the Fakhr-1 satellite for Iran’s military, the first time Iran’s civilian program is known to have carried a military payload.

This was Iran’s fourth launch in 2024, doubling the launch record it had set in 2023.

The leader board for the 2024 launch race remains unchanged:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 91, while SpaceX by itself leads the entire world, including American companies, 127 to 110.

Hubble takes a different look at quasar 3C 273

10:25 am

Hubble's different views of 3C 273
Click for original image.

One of the most studied objects in the sky is the quasar 3C 273, located about 2.5 billion light years away and the first quasar ever to be identified, in 1963. What makes it especially interesting is the 300,000-light-year-long jet that shoots out from it.

Astronomers have now used the Hubble Space Telescope to take a different view of 3C 273, using the telescope’s coronograph to block the central bright light so that the surrounding dimmer features can be seen. The two images to the right, reduced and sharpened to post here, show what this new image (bottom) reveals when compared to an earlier Hubble image (top).

The new Hubble views of the environment around the quasar show a lot of “weird things,” according to Bin Ren of the Côte d’Azur Observatory and Université Côte d’Azur in Nice, France. “We’ve got a few blobs of different sizes, and a mysterious L-shaped filamentary structure. This is all within 16,000 light-years of the black hole.”

Some of the objects could be small satellite galaxies falling into the black hole, and so they could offer the materials that will accrete onto the central supermassive black hole, powering the bright lighthouse.

What makes this observation even more outstanding is that the image was produced by using Hubble’s Space Telescope Imaging Spectrograph (STIS) as the coronograph to block the bright center of 3C 273. This improvisation of STIS has been done many times before, but it remains a great example of clever thinking by the astronomers who use Hubble.

Japan’s space agency admits first launch of its new Epsilon-S rocket will be delayed

10:01 am

Japan’s space agency JAXA yesterday admitted that the first launch of its new Epsilon-S rocket — intended to be cheaper and competitive with the new rockets being developed worldwide — will be delayed because of the explosion that occurred during a static fire test on November 26, 2024.

The news reports in the Japanese press don’t provide much information. It appears the investigation into the explosion is still on-going, and that the cause of the failure has not yet been identified. Because of this, JAXA has been forced to cancel the planned March 2025 date for Epsilon-S’s inaugural flight.

JAXA should get out of the business of building rockets, as its track record is really horrible. The Japanese government has already told it to do so, but it is clearly dragging its feet, not wanting to give up the turf it has controlled for decades.

Europe’s Vega-C rocket returns to flight after being grounded for more than two years

3:47 pm

Europe’s Vega-C rocket, built by the Italian company Avio but presently still managed by the European Space Agency’s commercial arm Arianespace, today successfully completed its first launch in two years, lifting off from French Guiana carrying a European Earth observation satellite. As of posting the satellite had not yet been deployed.

The rocket was first grounded when its upper stage failed during a December 2022 launch. The investigation pinpointed the problem as the design of the stage’s engine nozzle. However, the first redesign also failed, requiring a second redesign.

This was the eighth launch worldwide in the past 48 hours, the most ever accomplished in such a short time. All told, five nations completed launches (United States 3, China 2, India 1, Russia 1, Europe 1) from eight different spaceports, with all three American launches completed by SpaceX.

Because this was only the third launch by Europe this year, the leader board for the 2024 launch race remains unchanged:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 90, while SpaceX by itself leads the entire world, including American companies, 127 to 109.

Union official accuses Boeing of more unsafe practices

10:44 am

According Craig Garriott, a union representative at Boeing’s satellite-manufacturing facility in Los Angeles, Boeing’s management has been allowing numerous safety violations to go unfixed in order to focus on profits and fast production.

Acquired by Boeing in 2000, the satellite manufacturing facility has long been considered one of Boeing’s more stable business units. It relies in part on a union workforce that Garriott said is responsible for constructing and testing satellites and their component parts.

“This is perhaps the most technical group of hourly people that you’ll probably find on this planet,” said Garriott, who estimated he’s raised between 300 and 400 safety violations over the past year. Those complaints, he said, range from obstructed fire extinguishers and fire alarms to concerns over heavy machinery blocking exits and trapping workers in certain parts of the factory.

In October, union workers filed a complaint with the Occupational Health and Safety Administration that, according to Garriott, highlighted unsafe conditions on the factory floor. Another technician at the facility, who spoke to CBS News on the condition he remain anonymous to protect his job, said safety had become “an afterthought” and quality had “degraded” over the past five to six years.

It is important to recognize that Garriott’s complaints might simply be the typical tactic of a union representative during or before contract negotiations. There are rumors Boeing plans to sell off its space subsidiaries, which would include this satellite division. Garriott might simply be putting public pressure on the company in order to give himself a better negotiation position if such a sale takes place.

It is also quite possible, based on Boeing’s recent very poor track record in quality control, that everything Garriott says here is also true.

Sierra Space signs deal using its Dream Chaser mini-shuttles for in-space manufacturing

Sierra Space has now signed agreements with two different startups, Astral Materials and Space Forge, to use its Dream Chaser mini-shuttles for in-space manufacturing.

Astral Materials leverages the microgravity environment of space to grow ultra-high quality semiconductor crystals for advanced chip technologies. Space Forge harnesses free flying manufacturing facilities to produce next-generation materials for commercial industries, national security and research.

Up to now, Sierra’s only customer has been NASA, which wants to use Tenacity, the first Dream Chaser mini-shuttle, to hauling cargo to and from ISS. These new deals illustrate that there are other profit opportunities for the company’s reusable shuttle outside of government. As the startup Varda has already demonstrated with its own returnable capsule, there is money to be made manufacturing products in weightlessness that cannot be produced in the gravity of Earth.

The press release however has one additional tidbit that is intriguing. Sierra is a partner in the Blue Origin-led Orbital Reef commercial space station. It also appears to be the only partner that is actually building anything for that station, specifically its LIFE inflatable modules. The press release mentions that both these agreements include options for Astral and Space Forge to provide “input on Sierra Space’s future space stations.” That this press release does not refer to Orbital Reef here suggests once again that Sierra Space is somewhat dissatisfied with the output of its Blue Origin partner, and is thus creating options for it to build its own space station using those LIFE modules (shown above), should Blue Origin not deliver.

At a minimum, Astral and Space Forge will certainly be interested in doing manufacturing within those LIFE modules, should they end up being part of Orbital Reef.

Yuma competing for up to $160 million in an NSF grant to establish its own spaceport

10:16 am

Yuma spaceport

Arizona wants its own spaceport! The city of Yuma, located in Arizona’s southwest corner, is now a finalist in a National Science Foundation (NSF) grant program that could award it up to $160 million to establish a spaceport there.

The city is one of two Arizona applicants, the other being the University of Arizona, which wants to use the grant money “to make the state a proving ground for transformative mining technologies.” There are in addition 69 other applicants to the NSF grant.

This announcement is mostly PR, since Yuma not only does not yet have a spaceport licence from the FAA, it does not yet have approval from Mexico to fly missions over that country. Yuma is not on the coast, so launches must cross land. And if not over Mexico, launches would have to cross other U.S. states, something that would need approval as well.

This proposal has been in the works for many years, as having a spaceport in Arizona would draw a lot of space business to the state. It could happen, but to do so will require a lot of approvals from a lot of government agencies.

Republican California state legislator introduces bill to overturn California Coastal Commission’s effort to block SpaceX

9:46 am

Wants to be a dictator
Wants to be a dictator

Republican state assemblyman Bill Essayli has now introduced a bill that would overturn the decision by the California Coastal Commission to reject SpaceX’s request to increase its launch rate at Vandenberg spaceport, a decision the commissioners readily and publicly stated was made not to protect the state’s beaches (the commission’s prime function) but because they did not like Musk’s political positions.

“AB 10 will reverse the politically-motivated decision by the California Coastal Commission to restrict SpaceX launches for the Space Force due to their hatred of Elon Musk. This dangerous and illegal decision threatens our national security and erodes the public trust we place in our officials to act in the best interest of the people — not politics,” Essayli said in a statement this week.

SpaceX has already sued the commission and its commissioners for violating Musk’s first amendment rights as well as exceeding their statutory authority.

The bottom line however is that the commission’s decision carries no legal weight. Vandenberg is an federally operated military base, and thus this state commission has no authority to dictate what happens there. The Space Force has simply tried to work with it in the past.

Thus, if the commission’s fangs are not pulled by Essayli’s legislation as well as SpaceX’s lawsuit, the military will likely just ignore it.

Airbus cuts almost 500 jobs in Great Britain

9:30 am

As part of a larger planned belt-tightening that is expected to reducing staffing by more than 2,000, Airbus has now begun eliminating 477 jobs in its British operations.

The cuts are expected to hit the workforce in Stevenage and Portsmouth, where Airbus’s UK space operations are concentrated, while Newport in south Wales may also be impacted. The Stevenage site is also building Europe’s first Mars rover for a mission designed to search for signs of past or present life on the planet that’s due for launch in 2028.

Airbus said that only “overhead positions” – such as management support – will be hit, with nobody assigned to individual programmes or projects affected.

The company claims these cuts are due to SpaceX grabbing a large part of market share in the satellite business. It is also because Airbus is likely overstaffed, its operations shaped by the European Space Agency past requirement that it spread those operations to as many member nations as possible. These cuts in Great Britain are likely an attempt to reduce that spread.
