The Senate, led by Ted Cruz, endorses NASA’s failed SLS, Orion, and Lunar Gateway

9:48 am

Let’s all go bankrupt! A bill introduced today by Ted Cruz (R-Texas), chairman of the Senate Commerce Committee, rejects the Trump budget plan to phase out NASA’s failed SLS, Orion, and Lunar Gateway programs that have cost so far tens of billions for decades without accomplishing anything, and instead expands funding over the next decade to these and many other projects and agencies at NASA.

The bill would allocate $2.6 billion to Lunar Gateway, $4.1 billion to build two more SLS rockets, $20 million to build one more Orion capsule, $1.25 billion more for ISS to continue its operations as is, and $1 billion to upgrade or expand facilities at five NASA centers in Florida, Texas, Mississippi, Alabama, and Louisiana.

This pork-laden bill would also fund a Mars Telecommunications Orbiter for $700 million and add $325 million to the $843 million contract NASA has with SpaceX to build the de-orbit vehicle for bringing ISS down in a controlled manner once it is retired.

What this bill tells us is that these Senators, led by “lying” Ted Cruz (to use the nickname Trump pinned on him during the 2016 presidential election campaign), are still unwilling to face the realities of the national debt, and want to spend money we don’t have in order to make believe they are grand explorers sending Americans into space. Instead, these idiots are simply funneling cash to their states in order to bribe voters to vote for them.

As Elon Musk so correctly noted, there is an election coming in 2026. Maybe it is time to throw them all out.

What this bill also tells us is that Trump is going to find it very difficult to get the budget under control. The Senate doesn’t care if the country goes bankrupt. They intend to spend our money like it grows on trees, to hell with the future. Shame on them.

Sadly, these senators know they have the backing of almost the entire press corp, which is why they are doing this. They figure they will get great press for “saving” NASA, even if it bankrupts the country. Worse, it appears the press is all for helping them do so.

R.I.P. America.

Long delayed ESA project to build a reusable first stage delayed again

9:28 am

The long delayed European Space Agency (ESA) project dubbed Themis to develop and test a reusable first stage for use in European rockets has been delayed again, with the first test hop now expected to occur next year instead of the fourth quarter of 2025.

Themis was first proposed by ESA in 2019, with the first hops expected in 2022. Three years later little has happened in the project. Instead, it appears the nations in the ESA as well as the new rocket startups on that continent have grown very disinterested in government-run projects like this. The closing paragraph at the article at the link illustrates this starkly:

While another delay to the start of the first Themis launch campaign is frustrating, the downstream consequences are likely to be minimal. The only direct application of the technology developed under the Themis programme is the first stage of the two-stage MaiaSpace rocket. However, the company appears to be continuing the development of its first stage largely independently of Themis, meaning the latest delay is unlikely to affect its progress.

In other words, this whole program is divorced entirely from any commercial application. We should therefore expect that once these test flights finally occur, the entire thing will vanish, like so many other similar government-run test programs by NASA and ESA.

Ispace confirms that its Resilience lunar lander has failed, apparently crashing on the Moon

8:41 pm

According to an update issued several hours after the planned landing, the Japanese lunar lander startup confirmed that its Resilience lunar lander apparently crashed in its attempt to soft land on the Moon.

Ispace engineers at the HAKUTO-R Mission Control Center in Nihonbashi, Tokyo, transmitted commands to execute the landing sequence at 3:13 a.m. on June 6, 2025. The RESILIENCE lander then began the descent phase. The lander descended from an altitude of approximately 100 km to approximately 20 km, and then successfully fired its main engine as planned to begin deceleration. While the lander’s attitude was confirmed to be nearly vertical, telemetry was lost thereafter, and no data indicating a successful landing was received, even after the scheduled landing time had passed.

Based on the currently available data, the Mission Control Center has been able to confirm the following: The laser rangefinder used to measure the distance to the lunar surface experienced delays in obtaining valid measurement values. As a result, the lander was unable to decelerate sufficiently to reach the required speed for the planned lunar landing. Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface.

After communication with the lander was lost, a command was sent to reboot the lander, but communication was unable to be re-established.

This explanation fits with the very high velocity numbers seen as the spacecraft approached the surface, much higher than intended.

Ispace has now attempted to land on the Moon twice, with both landers crashing upon approach. In this sense its record is not quite as good as the American startup Intuitive Machines, which had two landers touch down but immediately tip over, causing both to fail.

Ispace presently has three contracts to build landers with NASA, JAXA (Japan’s space agency), and the European Space Agency. The American lander is being built in partnership with the company Draper. Whether this second failure today will impact any of those contracts is uncertain at this time.

China launches another set of satellites for one of its giant internet constellations

8:17 pm

China earlier today successfully launched the sixth set of satellites for the Thousand Sails internet constellation, its Long March 6A rocket lifting off from its Taiyuan spaceport in northern China.

Very little information appears available about this specific payload. No word also was released about where the rocket’s lower stages and four strap-on boosters crashed inside China.

The leaders in the 2025 launch race:

69 SpaceX
33 China
7 Rocket Lab
6 Russia

SpaceX still leads the rest of the world in successful launches, 69 to 53.

Scientists discover another exoplanet that theories say should not exist

10:20 am

The uncertainty of science: Scientists using telescopes both in orbit and on the ground have discovered a small red dwarf star with only 20% the mass of our Sun with a gas giant exoplanet with about half the mass of Saturn but a bit larger in size.

The problem is that the theory for the formation of such gas giants predicts that they should not form around small red dwarfs such as this star.

The most widely held theory of planet formation is called the core accretion theory. A planetary core forms first through accretion (gradual accumulation of material) and as the core becomes more massive, it eventually attracts gases that form an atmosphere. It then gets massive enough to enter a runaway gas accretion process to become a gas giant.

In this theory, the formation of gas giants is harder around low-mass stars because the amount of gas and dust in a protoplanetary disc around the star (the raw material of planet formation) is too limited to allow a massive enough core to form, and the runaway process to occur.

Yet the existence of TOI-6894b (a giant planet orbiting an extremely low-mass star) suggests this model cannot be completely accurate and alternative theories are needed.

You can read the paper here. The exoplanet orbits the star every 3.37 days, and each transit across the face of the star has been easily detected by numerous telescopes. Further spectroscopic observations using the Webb Space Telescope will be able to characterize the exoplanet’s atmosphere more fully.

Scientists release the first year’s data from the Pace orbiter

10:07 am

Pace global data, August 2024
Click for original movie.

Launched in early 2024, the Pace orbiter was designed to track the evolution of the leaves of trees globally throughout the entire year. NASA has now released the data from the first twelve months, showing the seasonal changes of trees as the Earth rotates the Sun and the seasons change globally.

The map to the right is a screen capture from one of many videos showing these changes. The green indicates the global spread of tree cover in the middle of August in the northern hemisphere as well as in the equatorial regions of South America and Africa. Other movies focusing on North America, South America, Europe, India, etc, can be viewed here.

PACE measurements have allowed NASA scientists and visualizers to show a complete year of global vegetation data using three pigments: chlorophyll, anthocyanins, and carotenoids. That multicolor imagery tells a clearer story about the health of land vegetation by detecting the smallest of variations in leaf colors.

…Anthocyanins are the red pigments in leaves, while carotenoids are the yellow pigments – both of which we see when autumn changes the colors of trees. Plants use these pigments to protect themselves from fluctuations in the weather, adapting to the environment through chemical changes in their leaves. For example, leaves can turn more yellow when they have too much sunlight but not enough of the other necessities, like water and nutrients. If they didn’t adjust their color, it would damage the mechanisms they have to perform photosynthesis.

In the visualization, the data is highlighted in bright colors: magenta represents anthocyanins, green represents chlorophyll, and cyan represents carotenoids. The brighter the colors are, the more leaves there are in that area. The movement of these colors across the land areas show the seasonal changes over time.

You can read the full paper describing the first year’s data here.

The Trump budget presently funds Pace for two more years of observations, at about $26 million per year. This is an obvious example of a satellite whose life should be extended for as long as possible. This long term data would likely confirm other data that indicates the increase in CO2 in the atmosphere is greening the Earth, helping plant life that provides us oxygen to breath and food to eat.

To do so, however, other cuts in NASA will have to be found to pay for that extension. I once again wonder about the half a billion NASA spends for its “Mission Enabling Services”, which covers NASA’s human resources division, public relations department, and its equal opportunity division, as well as other more useful departments. Surely some money from these bureaucratic divisions could be found to finance this actual useful research.

Watch the landing attempt of Ispace’s Resilience lunar lander

9:34 am

Map of lunar landing sites

Ispace’s Resilience

I have embedded the live stream below of the landing of the Japanese startup Ispace’s Resilience lunar lander, presently scheduled to occur at 3:17 pm (Eastern) today (June 6, 2025 in Japan).

The live stream goes live at about 2:00 pm (Eastern).

Resilience will attempt to land on the near side of the Moon at 60.5 degrees north latitude and 4.6 degrees west longitude, in the region dubbed Mare Frigoris (Latin for “the Sea of Cold”), as shown on the map to the right. That map also shows a number of other landings on this quadrant of the Moon, including Ispace’s previous failed attempt with its first lander, Hakuto-R1, in Atlas Crater in 2023.

For Ispace, today’s landing is critical for its future. It has contracts for future three landers with NASA, with Japan’s space agency JAXA, and with the European Space Agency, but a failure today could impact whether those contracts proceed to completion.

SpaceX launches more Starlink satellites

8:41 pm

SpaceX this afternoon successfully launched another 27 Starlink satellites, its Falcon 9 lifting off from Vandenberg Space Force Base in California.

The first stage completed its 26th flight, landing on a drone ship in the Pacific. Also, as noted by regular reader Richard M, this was also the 500th orbital launch of a Falcon rocket, including the Falcon 1, the Falcon 9, and the Falcon Heavy. And the company has done this in only a bit over fifteen years. Quite amazing.

The leaders in the 2025 launch race:

69 SpaceX
32 China
7 Rocket Lab
6 Russia

SpaceX now leads the rest of the world in successful launches, 69 to 52.

Two giant clusters of galaxies on target for second collision

3:55 pm

Colliding galaxy clusters
Click for full image.

Using telescopes both on Earth and in space, astronomers now think two giant clusters of galaxies that had collided previously have now stopping flying from each other and are on target for second collision.

The annotated image to the right shows what we can see today. The two blue blobs near the center are the two galaxy clusters.

The galaxy cluster PSZ2 G181.06+48.47 (PSZ2 G181 for short) is about 2.8 billion light-years from Earth. Previously, radio observations from the LOw Frequency ARray (LOFAR), an antenna network in the Netherlands, spotted parentheses-shaped structures on the outside of the system. In this new composite image, X-rays from Chandra (represented in purple) and ESA’s XMM-Newton (blue) have been combined with LOFAR data (red) and an optical image from the Pan-STARRS telescope of the stars in the field of view.

These structures are probably shock fronts — similar to those created by jets that have broken the sound barrier — likely caused by disruption of gas from the initial collision about a billion years ago. Since the collision they have continued traveling outwards and are currently separated by about 11 million light-years, the largest separation of these kinds of structures that astronomers have ever seen.

Now, data from NASA’s Chandra and ESA’s XMM-Newton, a mission with NASA contributions, is providing evidence that PSZ2 G181 is poised for another collision. Having a first pass at ramming each other, the two clusters have slowed down and begun heading back toward a second crash.

When such giant object collide what really interacts the most is the gas and dust between the stars. The motions of the stars and galaxies of course get distorted by the pull of gravity, but there are almost never any crashes.

Understanding Trump’s proposed NASA cuts, in the larger context of the overall federal budget

1:44 pm

U.S. debt as of June 4, 2025
U.S. debt as of June 4, 2025. Click for original.

For my entire life it has always been the same: Whenever any politician or elected official proposes any cuts to the federal budget, and most especially when those cuts are aimed at a popular government agency like NASA, the news reports in the mainstream press are uniformly hostile.

Trump’s proposal to cut NASA’s budget by 24% in 2026 has been no different. Here are just a few headlines:

This list is only a sampling, but they are typical of almost all the reporting now and that always happens when big cuts are proposed in any government program. The spin is always the same: “These cuts are horrible, their acceptance would be the act of a barbarian, and by doing so will certainly cause the fall of civilization!”

Above all, the focus is always on the cuts themselves, and never on the larger picture.

I am not going to do that. I have reviewed in detail the proposed cuts to NASA, and am now going to take a detailed look, but will do so by considering the larger context of the overall federal budget and the need to get its spending under control.

And out of control that budget is, as indicated by the screen capture above of today’s US Debt Clock. The United States is bankrupt. If we don’t gain some control over federal spending in a very near future some very bad things are going to happen, and soon. And those bad things will likely shut down luxury items like NASA entirely, not just impose some cuts to its overall budget.

All Trump is doing is attempting a first stab at this problem. The real question is whether he has made a rational and reasonable attempt, or whether it should be revised in some manner.

This is the perspective I bring to this issue. I just wish others would do the same.

Japanese lunar lander startup Ispace signs deal to build lander for ESA

10:10 am

Map of lunar landing sites

Ispace’s Resilience

The Japanese lunar lander startup Ispace — about to attempt its second unmanned lunar landing — has now signed a $3 millionj contract with the European Space Agency (ESA) to begin design and construction of its proposed Magpie lander.

The agreement comes in the context of the Small Missions for Exploration initiative launched by ESA. This initiative called for innovative and short-term mission ideas for lunar exploration. ispace’s MAGPIE concept was selected and awarded a pre-phase A contract on Dec. 12, 2024. Under the Phase 1 extension agreement, ispace-EUROPE will collaborate with ESA on the implementation of the lunar exploration mission. In aggregate, the value of the contracts for the two phases is €2,695,000 (approximately ¥437 million JPY).

The company already has contracts for future landers with both NASA and Japan’s space agency JAXA. It appears these space agencies consider the company’s engineering to be acceptable, even though its only attempt to land on the Moon, Hakuto-R1, crashed in 2023 when its software shut the engines down prematurely, three kilometers above the surface.

Ispace’s second lander, Resilience, is presently in lunar orbit and is now targeting a landing attempt tomorrow, June 5, 2025, at 3:17 pm (Eastern). The map to the right shows the landing zone, in Mare Frigoris in the high northern latitudes of the near side of the Moon.

This contract by ESA also illustrates Europea’s increasing shift to the capitalism model. Rather than design and build the lander itself, ESA is buying this product from the private sector. It will likely get what wants sooner and for far less money.

Orbital tug startup Impulse raises $300 million in private investment capital

9:57 am

Following several large contract announcements in recent weeks, the orbital tug startup Impulse has now raised an additional $300 million in private investment capital, in addition to the $150 million it raised last year.

Impulse plans to use the funding for several initiatives. One is to scale up production of its Mira and Helios vehicles to better meet demand for them. The company says it has more than 30 signed contracts for those vehicles, a backlog worth nearly $200 million. Romo said the company is seeing increasing demand for Mira, the smaller of the two vehicles, for defense applications.

The company was founded by Tom Mueller, who was one of the principal engineers during SpaceX’s development of the Falcon 9. Mira is the smaller of the two tugs, and has flown one demo mission. The larger Helios tug has not yet flown, but the company recently won a contract with the satellite company SES to use it.

The company has also said it is developing its own rocket, but I suspect its first launch that will come later.
