China and SpaceX complete launches

12:02 pm

Both China and SpaceX successfully completed launches today.

First, China completed the first launch of its Long March 8A rocket, an upgraded and more powerful version of its Long March 8 rocket. The rocket lifted off from China’s coastal Wencheng spaceport, and put the second batch (number unrevealed) of one of China’s new mega internet constellations.

Along with the basic Long March-8 model and the booster-free tandem configuration, it forms the Long March 8 series of rockets, providing a payload capacity range of 3 tons, 5 tons, and 7 tons to SSO. This significantly enhances China’s satellite networking capabilities for low and medium Earth orbits.

These rockets and the coastal spaceport will also allow China to steadily reduce its reliance on its older family of rockets that use toxic hypergolic fuels and launch from within China.

Next SpaceX launched another 21 Starliink satellites, including 13 with direct-to-cell capabilities, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 18th flight, landing on a drone ship in the Atlantic.

7 China

Astronomers catalog large ring systems surrounding 74 stars

11:32 am

74 rings surrounding stars
Click for original image.

Using a variety of ground-based telescopes in many wavelengths, astronomers have now produced a detailed catalog of 74 stars with large dust rings similar to the Oort cloud that is believed to exist at the very outer fringes of our own solar system.

The image to the right, reduced to post here, shows all 74 stars.

The new gallery shows a remarkable diversity of structure in the belts. Some are narrow rings, while others are wider and could be categorized more as “disks” than “belts”. Moreover, some of the 74 exocomet systems have multiple rings or disks and some of those are “eccentric,” meaning not a circular orbit but more like an oval. This provides evidence that yet undetectable planets or perhaps moons are present and their gravity affects the distribution of pebbles in these systems.

You can read the paper here [pdf].

The press release implies the discovery of “exocomets” but that is not true. The belts and rings mapped are likely to have comets in them, but no such comets have been found.

The scientists say that this database can be used to better understand the formation of solar systems, though they also admit that the “limited (although much improved) size of our sample” makes any conclusions based on it very uncertain. They hope however that over time that sample size will grow.

A Pakistani rover will fly on China’s Chang’e-8 mission to the Moon

9:18 am

Pakistan and China have finalized plans to place a Pakistani rover on China’s Chang’e-8 lunar lander mission.

This rover partnership was first announced in November 2024. This new release appears to provide a bit more information about the rover itself.

The rover will have a mass of around 35 kilograms and carry science payloads for studying lunar soil composition, radiation levels, plasma properties and testing new technologies for sustainable human presence on the Moon. It will also feature a collaborative scientific payload developed by Chinese and European researchers.

The Chang’e-8 mission is targeting a 2030 launch and will land in the Moon’s south pole region. China also claims it will initiate construction of China’s International Lunar Research Station (ILRS), but that’s a bit of hyperbole. All it shall be is another unmanned lander with two rovers and other instruments, hardly a manned base. What will matter will be what follows, and how quickly.

Blue Ghost leaves Earth orbit

Artist rending of Blue Ghost on the Moon

Firefly’s Blue Ghost lunar lander has successfully completed the mid-course correction engine burn that has taken it out of Earth orbit and into a transfer orbit to the Moon.

After a successful Trans Lunar Injection burn on Saturday, Feb. 8, Firefly’s spacecraft carrying NASA science and tech to the Moon has departed Earth’s orbit and begun its four-day transit to the Moon’s orbit. Blue Ghost will then spend approximately 16 days in lunar orbit before beginning its descent operations. Since launching more than three weeks ago, Blue Ghost has performed dozens of health tests generating 13 gigabytes of data. All 10 NASA payloads onboard are currently healthy and ready for surface operations on the Moon.

I post the artist’s rendering of Blue Ghost to the right to contrast its design with Intuitive Machines’ Odysseus lunar lander that fell over when it landed last year. Note how much lower to the ground Blue Ghost is. This will certainly reduce the chances it will have the same problem as Odysseus, even if one leg breaks upon landing.

A pimple on Mars

A pimple on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 1, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled simply as a “terrain sample,” it was likely not taken as part of any specific research project, but to fill a gap in the camera’s schedule in order to maintain its proper temperature. When the camera team does this they try to pick something interesting, and sometimes succeed.

I think they succeeded in this case. At first glance this appears to be a crater, but on closer inspection it is instead a small mound. The picture was taken in the winter, at the high latitude of 55 degrees north. The featureless white surface surrounding this dark mound is almost certainly the mantle of dry ice that falls as snow and covers the poles during the winter. If not that, it is then likely to be a water ice sheet that orbital data suggests covers much of Mars’ high latitudes.

The payloads on Intuitive Machines Athena lunar lander, including a hopper and a rover

9:32 am

The Moon's south pole, with candidate landing sites
Click for NASA’s original image.

Link here. Athena is scheduled for launch on February 26, 2025 on a SpaceX Falcon 9 rocket. The article is mostly focused on describing the Gracie hopper, which will attempt to hop into the permanent shadows inside a nearby crater.

Though no announcement has ever been made, it appears the landing site for this lander has been changed. Previously it had been targeting a ridge adjacent to Shackleton Crater, at the south pole and shown on the map to the right. That location however required a launch in January. The delay to February seems to have shifted the landing site.

If all goes to plan, Athena will land on a plateau just 100 miles (160 kilometers) from the moon’s south pole. This region is thought to be rich in water ice, and IM-2 will prospect for the precious resource with the help of some ride-along robots, including a pioneering hopper nicknamed Gracie.

Though I cannot find any specific information on where this location is, I strongly suspect it is the site that Intuitive Machines’ lander, Nova-C (also dubbed Odysseus), attempted to reach last year.

The yellow boxes on the map indicate NASA’s candidate landing zones for its Artemis-3 manned mission.

Germany commits almost a million dollars to build off-shore launch platform

9:08 am

The Germany government has now allocated $897,000 to a private consortium of four companies to help finance its promised but delayed an off-shore launch platform.

The North Sea launch platform is being developed by the German Offshore Spaceport Alliance (GOSA), a joint venture formed in December 2020 by Tractebel DOC Offshore, MediaMobil, OHB, and Harren Shipping Services. The platform will be constructed on the 170-metre-long Combi Dock I vessel and will accommodate launchers with a mass of between 36 and 52 tonnes. A 2020 feasibility study stated that the development and operation of the North Sea launch platform would cost between €22 and €30 million over six years.

The consortium had first announced the project in 2023, with the first launch of several suborbital test rockets in 2024. Since then little has been heard of this project, with those launches never occurring.

If built as promised, this platform would accommodate rockets as large as the Falcon Heavy. Its goal, besides offering the platform to all rocket companies, is apparently to give German rocket startups the option of a German spaceport so they don’t have to depend on other countries.

Falklands public wants the freedom to choose between OneWeb and Starlink

8:53 am

Even as the Falklands government is demanding its money back from OneWeb for not activating its service on time, it appears the public on those islands has buying and using Starlink terminals, even though it is presently illegal to use it there.

The high level of Starlink usage sparked a successful petition backed by 70% of the island’s population. This petition demanded both a reduction of the £5,400 FIG VSAT licence fee and formal approval for Starlink’s operation in the Falkland Islands.

In response, a Starlink Select Committee – comprising all of the island’s MLAs – convened from July to October 2024. The committee formally endorsed the petition’s demands, and the proposal was subsequently forwarded to the Falkland Islands Government (FIG) for implementation. However, the effective date for this approval has now been delayed until April.

Because Sure International holds an exclusive monopoly telecommunications licence, Starlink’s use in the islands is currently illegal. Nonetheless, this restriction has not prevented the widespread installation of hundreds of Starlink terminals, which remain unlicensed.

Sure International apparently provides internet service though traditional land lines. The cost difference compared to Starlink is considerable, with Starlink being far cheaper and providing much faster speeds. Meanwhile, OneWeb has failed to deliver and is losing this business. By April expect Starlink to be approved.
