Launch startup Spinlaunch raises $71 million more in private investment capital

Spinlaunch prototype suborbital launcher
Spinlaunch’s prototype launcher

Capitalism in space: The radical launch startup company Spinlaunch announced yesterday that it has raised an additional $71 million in private investment capital, bringing the total it has raised to $150 million.

Unlike the many rocket startups, Spinlaunch proposes launching payloads using a centrifuge. The image to the right is of its prototype smaller scale launcher, which has already completed several test launches.

The company claims its full scale launcher will begin operations by 2026, but it has not yet revealed where it will be built, which means construction has not yet begun.

Such a launch system cannot be used by any satellite with delicate equipment. The g-forces during launch are too high. However, for getting bulk cargo, like water and fuel into orbit, such a system could become very profitable, if it can be made operational.

Saudi Arabia buys two seats on Dragon for Axiom commercial flight to ISS

9:43 am

Capitalism in space: According to an as-yet unconfirmed story today by Reuters, Saudi Arabia has purchased two seats on a SpaceX Dragon capsule as part of an Axiom commercial flight to ISS.

The sources for the story are all anonymous, and no one from Axiom or SpaceX or Saudi Arabia has confirmed it. Nonetheless, it seems entirely plausible, since Saudi Arabia has made it clear it is considering such a mission and Axiom and SpaceX are eager to sell tickets.

Webb’s first infrared image of Neptune

9:30 am

Webb's infrared view of Neptune
Click for full image.

The science team for the James Webb Space Telescope today released that telescope’s first infrared image of Neptune.

That image is to the right, cropped and reduced slightly to post here. It is, as the press release touts, the best view in decades of Neptune’s rings. From the caption:

The most prominent features of Neptune’s atmosphere in this image are a series of bright patches in the planet’s southern hemisphere that represent high-altitude methane-ice clouds. More subtly, a thin line of brightness circling the planet’s equator could be a visual signature of global atmospheric circulation that powers Neptune’s winds and storms. Additionally, for the first time, Webb has teased out a continuous band of high-latitude clouds surrounding a previously-known vortex at Neptune’s southern pole.

The dots around the gas giant are the heat signatures of seven of its fourteen moons.

OneWeb announces delivery of 36 satellites to India for launch

9:17 am

Capitalism in space: OneWeb yesterday announced the delivery of 36 satellites to India for launch on that nation’s biggest rocket, the GSLV-Mark3.

Though no date for launch was mentioned, the press release did say this:

One additional launch will take place this year and three more are targeted for early next year to complete the constellation.

This suggests two launches before the end of the year, one by India with the second already contracted to SpaceX. As for the three launches next year, it is unclear yet who will launch them. OneWeb has contracts with SpaceX, Relativity, and NewSpace India Limited (NSIL), the commercial arm of India’s government space program which is doing this year’s GSLV launch. While Relativity has not yet launched, either SpaceX or NSIL could handle those launches for sure next year.

Hydrogen leak detected during today’s SLS tank test

9:08 am

Though engineers have apparently overcome the issue so that today’s tank test of NASA’s SLS rocket can continue, a hydrogen leak was nonetheless detected during fueling.

The fueling tank test is not yet complete.

At this moment I cannot imagine the military’s range office will allow NASA to launch on September 27th, as the agency has requested. To do so will require the range to ignore the possibility that the flight termination is inoperable, as its batteries are past their use-by date by almost a month. Combined with these ongoing leak issues, it would be irresponsible to do otherwise.

Russia launches three astronauts to ISS; China launches Earth observation satellite

9:02 am

Russia today successfully used its Soyuz-2 rocket to launch three astronauts to ISS, two Russians and an American flying as part of the NASA-Roscosmos barter deal whereby each agency flies an astronaut from the other in order to make sure everyone knows how to use each other’s equipment.

China in turn today used its Long March 2D rocket to launch an Earth observations satellite into orbit.

The leaders in the 2022 launch race:

42 SpaceX
38 China
12 Russia
7 Rocket Lab
5 ULA

American private enterprise still leads China 58 to 38 in the national rankings, and is now tied with the entire world combined at 58.

InSight’s power level holding steady

9:57 pm

InSight's on-going power levels

The Energizer bunny of Mars, the InSight lander, continues to hold on. The engineering team tonight issued another status report, as shown in the graph to the right. For the past week the lander continued to produce 420 watt-hours per day, even though the tau level of dust in the atmosphere increased from 0.8 to 0.85.

The tau level of dust outside of the winter dust season is normally between 0.6 and 0.7. Even though Mars is moving out of winter, that level has increased slightly above InSight. And yet, even with a higher dust content and thus less sunlight, the lander’s dust-covered solar panels are generating power, at a very slightly higher level.

The InSight team had expected the lander to die in early September, at the latest. Instead, it keeps running, thus allowing it to detect on September 5th an impact created by a cluster of three asteroids, the first time scientists have ever pinpointed exactly when such a new impact occurred on Mars.

For the lander to survive for even longer, all it needs is one gust of wind across the solar panels to clean them off. The science team had expected this to happen periodically, based on past experience with the Spirit and Opportunity rovers. Unfortunately for InSight, it has not yet happened even once since it arrived on Mars in 2018. Nonetheless, it only has to happen once to save the lander.

Stay tuned. All is not yet lost.

Jupiter’s endless interweaving storms

Jupiter's endless interweaving storms

Cool image time! The photo to the right, rotated so that north is up and then reduced slightly to post here, was created by citizen scientist Thomas Thomopoulos from a raw photo taken by Juno during its 44th orbit of Jupiter.

To bring out the details Thomopoulos enhanced the colors, then enlarged the entire photo and cropped the area of interest.

Unfortunately, the Juno team that releases these photos does not provide information for easily establishing scale. In an email to me Thomopoulos noted that the largest circular storm in the northern half of the image is likely a vortex, which on Jupiter tend to range from 600 to 3,500 miles in diameter. He also noted that Juno was a little less than 27,000 miles away from Jupiter when this photo was snapped on August 17, 2022. Thus, I suspect this particular vortex sits on the larger end of that size range, which makes it a little less than half the size of the Earth.

As for the colors, as with many similar Juno images, the white clouds appear to almost always sit at the top of these storms and jets, almost like thunderheads.

Though the largest feature here is that large vortex to the north, most of the gigantic Jupiter storms visible seem instead to form as bands, the storms churning about madly as they are driven along the gas giant’s very fast ten hour rotation period.

Today’s blacklisted American: Republicans and conservatives increasingly unwilling to talk to pollsters out of fear

12:45 pm

Joe Biden's
Joe Biden’s anti-conservative rally on September 1, 2022

Blacklists are back and the Democrats have got ’em: According to pollsters, the vicious almost slanderous attacks by President Biden against Republicans and conservatives — following decades of similar harsh language from Democrats nationwide — is causing these voters to increasingly refuse to talk to pollsters about their opinions.

In a Twitter thread, Trafalgar Group chief pollster Robert C. Cahaly said that President Joe Biden’s recent attacks on so-called “MAGA Republicans” will make polling supporters of former President Donald Trump even harder to poll than in previous years. Cahaly pointed out that in the last two presidential election cycles, name-calling and threats from prominent Democrats contributed to the phenomenon of the “shy Trump voter.” But as the 2022 midterms have begun in earnest, Biden’s escalating rhetoric against Trump supporters, accusing them of embracing “semi-fascism” and being a threat to America, will make these voters even harder to reach in polling.

NASA releases new overall objectives for exploration of solar system

11:28 am

NASA today released a new roadmap for its goal of exploring the Moon, Mars, and the rest of the solar system, with the goal of providing an overarching strategy for everything it hopes to accomplish.

The resulting revised 63 final objectives reflect a matured strategy for NASA and its partners to develop a blueprint for sustained human presence and exploration throughout the solar system. They cover four broad areas: science; transportation and habitation; lunar and Martian infrastructure; and operations. The agency also added a set of recurring tenets to address common themes across objectives.

You can read the full document here [pdf].

The most astonishing thing about this roadmap is its utter lack of any mention of race or gender, especially when one considers how obsessed the Biden administration and its minions in federal bureaucracy have been over such things. The goals are entirely focused on exactly what they should be focused on, exploration and research, with the goal of partnering with as many private and governmental entities as possible to get it done in the most efficient way.
