India gets nine bids involving 30 companies on proposal to build satellite constellation

4:01 pm

Capitalism in space: India’s space agency in charge of promoting commercial space, In-Space, has received nine different bids involving 30 Indian companies on its proposal that an Earth observation satellite constellation be built by a private company, not by the country’s space agency ISRO.

The regulator had sought “expressions of interest” (EoI) in July to build home-grown satellite constellations as part of a broader strategy to monetize the sector and ensure data sovereignty.

India is doubling down on its small satellite and data services market to carve out a leading role in the global commercialization of space. The market for such services, increasingly key for industries ranging from telecoms to climate monitoring, is projected to reach $45 billion by 2030.

The applicants for IN-SPACe’s latest effort in this regard include startups such as Google-backed Pixxel and Baring Private Equity-backed SatSure, as well as larger entities like Tata Group’s Tata Advanced Systems. The companies did not immediately respond to requests for comment.

This is all part of the Modi government’s effort to shift from a government-run space program, controlled by ISRO, to the capitalist model where private companies compete for business and there is no “program” at all, at least not one that controls everything. The government becomes nothing more than one of many customers, buying services and products from the private sector to achieve its “program”. The companies in that sector then follow their own goals, and profit and innovation dictate who succeeds best. The result under this freedom model is always more development faster for less cost.

A fading supernova 650 million light years away

10:18 am

A fading supernova 650 million light years away
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope in March 2024, and shows the fading blue light of a supernova that was first discovered by another survey telescope six weeks earlier. The galaxy, dubbed LEDA 22057, is estimated to be about 650 million light years away.

The supernova is the bright spot in the galaxy’s southeast quadrant near the edge of the galaxy’s bright body. From today’s caption release:

SN 2024PI is classified as a Type Ia supernova. This type of supernova requires a remarkable object called a white dwarf, the crystallised core of a star with a mass less than about eight times the mass of the Sun. When a star of this size uses up the supply of hydrogen in its core, it balloons into a red giant, becoming cool, puffy and luminous. Over time, pulsations and stellar winds cause the star to shed its outer layers, leaving behind a white dwarf and a colourful planetary nebula. White dwarfs can have surface temperatures higher than 100,000 degrees and are extremely dense, packing roughly the mass of the Sun into a sphere the size of Earth.

While nearly all of the stars in the Milky Way will one day evolve into white dwarfs — this is the fate that awaits the Sun some five billion years in the future — not all of them will explode as Type Ia supernovae. For that to happen, the white dwarf must be a member of a binary star system. When a white dwarf syphons material from a stellar partner, the white dwarf can become too massive to support itself. The resulting burst of runaway nuclear fusion destroys the white dwarf in a supernova explosion that can be seen many galaxies away.

The rate in which this supernova fades will help astronomers untangle the processes that cause these gigantic explosions. Though the caption makes it sound as if we know how this happens, we really don’t. There are a lot of assumptions and guesses involved in the description above, based on the limited knowledge astronomers have gathered over the past few centuries looking at many supernovae many millions of light years away.

ESA approves a slightly smaller preliminary budget for 2025

9:26 am

The council running the European Space Agency (ESA) has now approved a preliminary budget for 2025 of $8 billion, a very slight reduction from the 2024 budget.

According to [ESA’s director general Josef] Aschbacher, the budget includes €4.8 billion in contributions from ESA member states, approximately €1.7 billion from the European Union, and €1.2 billion from “some other sources.” A more detailed breakdown of the 2025 ESA budget will be released during the DG’s annual press briefing, which is expected to occur on 9 January 2025.

It is also expected that the final budget will be higher once the legislatures of ESA’s numerous member states approve their contributions to the agency. Right now German, France, and Italy are the largest contributors. All three governments have in the past two years clearly signaled their determination to support commercial space. This should translate into support for ESA, though the two are becoming increasingly separated. Those nations could also decide there is no reason to give cash to this bureaucracy, and instead use it to directly fund their new private rocket startups.

China replaces head of its space agency

9:16 am

The man who has headed China’s space agency since 2018 during its most aggressive and successful period, Zhang Kejian, has been replaced by the Chinese government. Zhang has also been removed from another important political post.

Zhang, 63, who has been head of the China National Space Administration (CNSA) since May 2018, is to be removed as Party Secretary of the State Administration for National Defense Science, Technology, and Industry (SASTIND), the agency announced Dec. 26. Shan Zhongde, 54, has been appointed as his replacement. The leader of SASTIND typically also heads CNSA and the China Atomic Energy Authority, both of which are subordinate agencies to SASTIND. CNSA has yet to announce the expected change.

China’s state run press provided no explanation for this change, though it also follows the removal of two other high ranking managers this year from another space agency, CASC, that is supervised by CNSA. Those removals are thought related to reports of corruption.

In the past two decades CNSA administrators went on to become heads of Chinese provinces, the approximate equivalent of a state governor in the U.S. and a somewhat powerful position. It appeared the Xi government was using its space agency as a training ground for its future political leaders. This in turn gave its space operations a favorable political position within the government.

Zhang’s removal in this manner and the rumors of corruption suggest this policy failed in his case. Another possibility is ven more significant if true. It might imply Zhang was involved in some power struggle that threatened Xi and his leadership. If this last possibility is so, the present favored political position of China’s space operations might be seriously threatened. Xi might have decided he did not like the power its leaders have garnered, and is now moving to squash it.

This does not mean the government will now move to reduce its space effort. It could mean however that funding will be more closely watched, and new projects questioned and rejected more easily.

SpaceX completes two launches tonight from opposite coasts

10:09 pm

SpaceX tonight successfully completed two launches. First it placed 20 Starlink satellites into orbit (including 13 configured for direct-to-cell capabilities), its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its sixteenth flight, landing on a drone ship in the Pacific.

Next SpaceX successfully launched four satellites for the smallsat startup Astranis, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its seventh flight, landing on a drone ship in the Atlantic, while the two fairing halves completed their 12th and 22nd flights.

Astranis had previously launched one demonstration satellite, proving that its smallsat design could do the work in geosynchronous orbit traditionally done by much larger and more expensive satellites. The four satellites on this launch are its first attempt to provide commercial service. If successful it places this American company in a good position to grab the market share from the older geosynchronous companies like Intelsat, SES, and Eutelsat.

The leaders in the 2024 launch race:

136 SpaceX
65 China
17 Russia
14 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 156 to 97, while SpaceX by itself leads the entire world, including American companies, 136 to 117.

Roscosmos buys Earth observation data from private Russian satellite company

11:05 am

According to a report today by Russia’s state-run news agency TASS, Roscosmos has awarded a commercial contract to a private Russian satellite company, dubbed Sputnix, to purchase earth observation data its satellites have already collected.

“In 2024, up to 1.4 billion rubles [around $14.285 million] were allocated in budget funds to conclude forward contracts with private companies on buying out Earth’s remote sensing data obtained from their satellites and created under the federal project ‘Developing the Advanced Space Systems and Services High-Tech Sector.’ The first contract on buying out data has been concluded with the Sputnix Group of Companies,” Roscosmos said in a statement.

The Sputnix Group confirmed to TASS that the contract had been signed.

“Under the contract, the data already loaded into the database were bought out. We hope that next year we will be able to sign a forward contract as part of implementing the roadmap for the ‘Advanced Space Systems and Services’ project,” the company said, emphasizing that cooperation with Roscosmos remained a priority for Sputnix.

Sputnix was founded in 2011, and has so far launched 20 satellites into orbit, though many were short-lived cubesats. While on the surface this company appears real, it is not unlike the pseudo-companies in China. Its contracts appear to be almost all with the Russian government, all its work appears supervised by that government, and at any moment the Russian government can take it over, as it essentially did with the effort of the so-called private rocket startup S7 to launch from the Sea Launch ocean platform.

In other words, this news piece is simply the Russian government’s attempt to convince the world and its own people that there is a competitive and independent private sector in Russia, when in reality it doesn’t exist.

Blue Origin completes first full dress rehearsal countdown and static fire test of New Glenn

8:43 pm

Blue Origin today successfully completed the first full dress rehearsal countdown and static fire test of its New Glenn orbital rocket at its launchpad at Cape Canaveral.

The tanking test included a full run-through of the terminal count sequence, testing the hand-off authority to and from the flight computer, and collecting fluid validation data. The first stage (GS1) tanks were filled and pressed with liquefied natural gas (LNG) and liquid oxygen (LOX), and the second stage (GS2) with liquid hydrogen and liquid oxygen–both to representative NG-1 set points.

The formal NG-1 Wet Dress Rehearsal demonstrated the final launch procedures leading into the hotfire engine run. All seven engines performed nominally, firing for 24 seconds, including at 100% thrust for 13 seconds. The test also demonstrated New Glenn’s autogenous pressurization system, which self-generates gases to pressurize GS1’s propellant tanks.

According to the company, the test achieved all its engineering goals, apparently making it ready for its targeted January 6, 2025 launch date. Beforehand however it will be rolled back into the assembly building so that its payload, Blue Origin’s Blue Ring orbital tug, can be stacked inside the fairings to fly a demo mission for the military.

Blue Origin finally gets FAA license to launch New Glenn, now targeting January 6, 2025

2:27 pm

The first completely assembled New Glenn, on the launchpad

The FAA, after months of apparent delays, today finally issued Blue Origin a license to launch its New Glenn rocket for a period covering the next five years.

As has now become the FAA’s custom, in issuing this license it also brags about its success in issuing the license “well in advance of the statutory deadline” for doing so.

What a crock. Blue Origin and NASA were originally targeting an October launch of New Glenn carrying two Mars orbiters, but had to cancel when the rocket couldn’t lift off during the six-day launch window. Though delays at Blue Origin certainly contributed to this cancellation, I suspect the FAA’s red tape played a major factor as well.

According to another source, Blue Origin is now targeting a launch date of January 6, 2025. The company is presently doing a static fire test on the launchpad.

Why this place in Valles Marineris is NOT a good place to establish trails and inns

11:57 am

Overview map

North rim and the top of the trail
Click for original image.

In my cool image yesterday I highlighted a location along the north rim of the gigantic Valles Marineris canyon on Mars that appeared a great place to establish a hiking trail. The trail would take hikers down from the rim to the floor of the canyon, a distance of more than 20 miles with an elevation loss of more than 31,000 feet, more than the height of Mount Everest. The image to the right shows the top of that trail, at the rim. The white dot on the overview map above shows its location in Valles Marineris.

Because of the trail’s length I also suggested that future colonists would likely set up inns along the way, so that hikers would have places to stay as they worked their way downhill day-by-day.

There is however one major reason not to build at this particular location, and it involves the most significant geological detail I noticed in the picture to the right. Note the arrows in both this image as well as the inset above. In the picture they mark a sudden drop paralleling the rim. In the inset they also show a series of parallel cracks further north.

The cliff and the cracks suggest that the entire cliff of this part of the north rim has subsided, and is in fact beginning to separate from the plateau, and will soon (in geological terms) collapse into a spectacular avalanche. If you look at the cliff face in the inset you can see two extended outflow piles that apparently came from smaller earlier such collapses.

Could this entire cliff face, the size of Mount Everest, actually separate and crash into the canyon? If you have doubts, then take a look at the image below.

Eutelsat-OneWeb stock plummets

10:02 am

Despite its merger with Eutelsat in 2023, the stock value of the combined Eutelsat-OneWeb satellite company has plummeted in the past year, more than halving the value of the OneWeb portion that was saved from bankruptcy by both the government of the United Kingdom and investors from India in 2020.

The collapse means the UK’s investment is worth €133m (£110m), representing a near £300m paper loss for the taxpayer. … However, while the all-share deal implied a value of €12 per share, Eutelsat’s stock has since imploded. In the past 12 months, it has halved and is trading at record lows of €2.58.

Eutelsat was facing its own collapse before the merger, as its business was geosynchronous communications satellites which are now losing their business to the low-Earth orbit constellations such as SpaceX’s Starlab and OneWeb’s. The merger was the company’s attempt to join this new market.

OneWeb however has had its own repeated problems completing that its constellation, and faced bankruptcy in 2020 because of delays from the COVID panic as well as delays in launching the Ariane-6 rocket. Then Russia’s invasion of the Ukraine in 2022 meant it lost all its remaining planned launches, forcing it to scramble to find other launch providers.

Stock market analysts don’t expect the combined company to begin earning profits for at least the next three to five years, which casts an even greater pall on its future.

Parker probe phones home, signalling it has successfully survived its record-breaking closest approach to the Sun

9:42 am

Parker flight plan
The flight plan for Parker. Click for original.

NASA today reported that it has received a signal from the Parker Solar Probe, indicating all of its systems are in good health following its record-breaking closest approach to the Sun on December 24, 2024.

The mission operations team at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland received the signal just before midnight EST, on the night of Dec. 26. The team was out of contact with the spacecraft during closest approach, which occurred on Dec. 24, with Parker Solar Probe zipping just 3.8 million miles from the solar surface while moving about 430,000 miles per hour.

Not only was this the closest any human-built object has gotten to the Sun, it was the fastest any human-built object has ever traveled.

This close fly-by was Parker’s 22nd of the Sun since launch. In its nominal mission it plans to do two more close approaches as shown in the graphic to the right, both of which will be comparable to the record just set.

Chinese solid-fueled rocket fails during launch

9:26 am

The commercial division of a Chinese space agency, dubbed CAS Space, late yesterday experienced a launch failure of its solid-fueled Kinetica-1 rocket, lifting off from the Jiuquan spaceport in northwest China.

A statement by the pseudo-company described the failure tersely:

We can confirm that the first two stages were nominal. Stage 3 lost attitude three seconds after ignition and the self-destructing mechanism was activated.

Nothing was said about where the first two stages crashed inside China, or whether they landed near habitable areas.

According to the first link above, this was the second launch failure by China in 2024, which is incorrect. This was the third launch failure for China (see here and here for previous two). That article also says this was the 68th total launch this year, suggesting China has completed 66 successful launches. This does not jive with my count, which presently says China has had 64 successful orbital launches this year. I suspect the two additional launched might have been suborbital tests — such as first stage hop tests (here, here, and here) — which I do not include in these totals. It also might be including the accidental launch of one first stage during a static fire test when it broke free and launched itself unintentional.

More recent information from my readers (see the comments below) suggests that, though the numbers above are not correct, my own count for China’s total successful orbital launches needs adjusting as well. I had marked a March 13th Chinese launch as a failure because the satellites were not placed in their proper orbit. However, using their thrusters engineers were eventually able to get them into place and they are operating. I have therefore increased China’s totals below by one.

The leaders in the 2024 launch race:

134 SpaceX
65 China
17 Russia
14 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 154 to 97, while SpaceX by itself leads the entire world, including American companies, 134 to 117.
