European nations struggle with the new private commercial space station concept

8:59 am

The European partners that have been doing research and work on ISS are now struggling to figure out their future on the multiple new private commercial space stations American private enterprise is now building to replace ISS.

The ISS today relies extensively on barter arrangements among participating agencies, providing services to cover their share of operations of the station. Such arrangements are unlikely to work for commercial stations, however. “We need to find a new way of cooperating,” said Nicolas Maubert, space counselor at the French Embassy in the U.S. and representative of the French space agency CNES in the U.S., citing the challenges of extending current barter arrangements to commercial stations. “We need to put on the table every option.”

The simplest approach — direct payments from space agencies to the companies operating commercial stations — could face political obstacles. “The taxpayers in Europe don’t want to pay directly to private American companies,” he said. [emphasis mine]

The highlighted words illustrate the fundamental problem. Europe on ISS has been for decades like a welfare queen. It has gotten access to space mostly free, since what it has offered in exchange for that access has never come close to matching what its work on ISS cost American taxpayers. Now that it will have to pay for that access in real dollars, some of its member nations are balking.

France for example still wants a free ride. Maubert suggested that Europe build its own space station, which means France wants its other ESA partners to help pay for the station that France wants to use.

I say, too bad. The costs on the private stations — built for profit and efficiency — will be far less that ISS. That cost will also be far far less than anything Europe might spend trying to build its own government station. Europe should bite the bullet and pay up. It won’t regret it.

Boeing’s write-off due to Starliner delays goes up to nearly $900 million

8:45 am

Capitalism in space: In a SEC filing on October 26, 2022, Boeing revealed that it has been required to spend another $195 million to cover the additional costs due to the further delays in getting Starliner launched, bringing the company’s total expense now to $883 million.

Boeing acknowledged today that it is taking a further $195 million charge against earnings for the CST-100 Starliner commercial crew program. Developed through a fixed-price contract with NASA, Starliner has encoutered a number of delays and Boeing must cover those costs. Added to $688 million already taken, the company now is spending $883 million of its own money on the program.

Boeing’s original fixed-price contract was for $4.2 billion, and included the test flights as well as six operational flights to ISS. However, numerous problems caused repeated delays and the need to fly a second unmanned test flight. Originally planned for the spring of 2020, the first manned Starliner flight is now targeting February 2023, three years behind schedule. Due to that delay, SpaceX’s Dragon ended up getting new contracts that included many of the later operational flights that Boeing would have earned. Right now, even if the capsule begins flying in ’23, NASA’s already purchased six flights will cover its needs through around ’26.

After that, NASA will still need to buy manned flights, if only to get to the new commercial space stations being built, and Starliner will then be an option. This just means however that it will take Boeing a long time to recover its Starliner losses. And that assumes customers begin to line up to buy flights.

Martian rectilinear ridges

1:16 pm

Martian rectilinear ridges
Click for original image.

Today’s cool image is also a bafflement. The photo to the right, cropped, reduced, and enhanced to post here, was taken on July 25, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The ridges in this picture are labeled by the scientists “Rectilinear Ridges,” but they really do not resemble any of the Martian rectilinear ridge types outlined in this paper [pdf], all of which appear to have a much more pronounced criss-cross pattern.

These ridges however are more meandering, and instead to my eye seem more like inverted channels, ancient channels whose beds became compacted and then became ridges when the less dense surrounding material eroded away. The problem with this conclusion however is the lack of any obvious tributary pattern. If these were once channels where either liquid water or glaciers once flowed, none of them seem to exhibit any drainage pattern. The ridges go in all directions.

The context map below only increases the mystery.

Orbit Fab, the company building gas stations in space, gets new investor

8:51 am

Though the amount invested has not been revealed, Orbit Fab announced yesterday that it has obtained a new investor to fuel its effort to build the first gas stations in space.

Orbit Fab said that 8090 Industries was a “new major investor” in the company, but did not disclose the size of the investment. The company had previously raised a total of $17 million, including more than $10 million in a September 2021 round that included Lockheed Martin Ventures and Northrop Grumman.

Orbit Fab’s goal is to provide satellite makers a way to more easily and cheaply refuel their satellites, thus allowing them to not only launch for less cost but to last longer once in orbit. In August it announced it is aiming to launch a hydrazine refueling depot for geosynchronous satellites by 2025.

Lucy's planned route
Lucy’s planned route to explore the Trojan asteroids

In the days prior to its October 16, 2022 fly-by of the Earth, the Lucy asteroid probe took several calibration images of the Earth and the Moon. The photo above, cropped, reduced, and enhanced to post here, shows both the Earth and the Moon together. From the caption:

On October 13, 2022, NASA’s Lucy spacecraft captured this image of the Earth and the Moon from a distance of 890,000 miles (1.4 million km). The image was taken as part of an instrument calibration sequence as the spacecraft approached Earth for its first of three Earth gravity assists. These Earth flybys provide Lucy with the speed required to reach the Trojan asteroids — small bodies that orbit the Sun at the same distance as Jupiter.

In the original, the Moon is so dim, compared to the Earth, that it was hard to find in the picture. I therefore brightened it considerably more than the Earth to make it easily seen above.

After 50 years Edward Stone retires as the project scientist for Voyagers 1 and 2

8:23 am

Edward Stone, the only project scientist the interstellar spacecraft Voyagers 1 and 2 have ever known, has now retired after 50 years service.

Stone accepted scientific leadership of the historic mission in 1972, five years before the launch of its two spacecraft, Voyager 1 and Voyager 2. Under his guidance, the Voyagers explored the four giant planets and became the first human-made objects to reach interstellar space, the region between the stars containing material generated by the death of nearby stars.

Until now, Stone was the only person to have served as project scientist for Voyager, maintaining his position even while serving as director of NASA’s Jet Propulsion Laboratory in Southern California from 1991 to 2001. JPL manages the Voyager mission for NASA. Stone retired from JPL in 2001 but continued to serve as the mission’s project scientist.

The new Voyager project scientist however is not new to the project.

Linda Spilker will succeed Stone as Voyager’s project scientist as the twin probes continue to explore interstellar space. Spilker was a member of the Voyager science team during the mission’s flybys of Jupiter, Saturn, Uranus, and Neptune. She later became project scientist for NASA’s now-retired Cassini mission to Saturn, and rejoined Voyager as deputy project scientist in 2021.

InSight still hangs in, barely

11:43 pm

InSight's power status as of October 22, 2022

A new update on the status of the Mars lander InSight was released today, showing its power output daily through October 22, 2022. The graph to the right shows this update. From the report:

As of October 22, 2022, InSight’s seismometer is collecting data again after being switched off to conserve energy after a recent dust storm. The lander was generating an average of 280 watt-hours of energy per Martian day, or sol. The tau, or level of dust cover in the atmosphere, was estimated at 1.45 (typical tau levels outside of dust season range from 0.6-0.7).

These power levels are very low, so low I am surprised the science team thought it was able to start the seismometer again. It could be they expect the lander to fail any moment, and decided to maximize the data it can get in the little time it has left.

A press conference is planned for Thursday, October 27, 2022 to provide an update on InSight’s future, as well it appears to describe a recent discovery (likely the exact moment some recent impacts took place) based on data from InSight and images from Mars Reconnaissance Orbiter (MRO). This was already reported in mid-September, but more impacts might have been identified.

It is also possible the MRO images detected some other change on the surface (not an impact) that InSight’s seismometer picked up. If so, the briefing will be far more interesting.

Russian Progress freighter successfully launches to ISS

11:20 pm

Using its Soyuz-2 rocket Russia tonight successfully launched a new Progress freighter to ISS.

The spacecraft will take two days to rendezvous and dock with ISS, thus delivering 2.5 tons of cargo.

The leaders in the 2022 launch race:

48 SpaceX
45 China
18 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 68 to 45 in the national rankings, though it now trails the rest of the world combined 72 to 68.

  • Protein crystal experiment to be launched on next Cygnus freighter to ISS

    • The tweet includes a cool picture of a protein crystal. From the experiment’s abstract:

    The Ring Sheared Drop investigation examines the formation and growth of amyloids and fibrils without the complications associated with the solid walls of a container, because in microgravity, surface tension provides containment of the liquid. Fibrous, extracellular protein deposits found in organs and tissues, amyloids are associated with neurodegenerative diseases such as Alzheimer’s. Results could contribute to better understanding of these diseases as well as to development of advanced materials.

    Forgive me if I am skeptical about this work. Protein crystal experiments have been going on on ISS now for more than two decades, without any clarity whether any have actually turned out useful on Earth. When I have seen presentations about them, I have repeatedly wondered if this isn’t more about creating papers and funding, not actual new knowledge that has a useful application.

    If I am wrong I would love to be educated otherwise.

China’s Long March 5B rocket with new space station module is now at launchpad

10:16 am

China’s Long March 5B rocket had now been rolled out to its launchpad, carrying the new Mengtian module for China’s Tiangong-3 space station.

The launch is presently scheduled for October 31, 2022. Assuming China has not upgraded the engines on the rocket’s core stage, that stage will tumble back to Earth, uncontrolled, sometime in the following week. Since it is large enough to survive re-entry, it will hit the ground, thus threatening every habitable location under its orbital path. By allowing this to happen China violates the Outer Space Treaty, to which it is a signatory.

Nor will this likely be the last time China does this. Though this module completes China’s station, as presently designed, this will not be the last Long March 5B launch. China plans to use it put its Hubble-class space telescope into orbit, as well as other things.

Relativity edges closer to first launch

9:59 am

Relativity has begun stacking its Terran-1 rocket with a goal of soon rolling it out to the launchpad for static fire tests.

The launch date itself remains uncertain. Though the company hopes to lift-off before the end of the year, it also has not committed to that goal.

“We are confident in our tech readiness to launch this year, and we’re still marching toward that,” Ellis said. “But there are a few external factors as we’re getting close to the end of the year that could impact the timeline for us. It’s not a guarantee, but it could.”

Those external factors include other spaceport users in Florida, including uncertainty around the mid-November launch of NASA’s Space Launch System rocket, and blackout periods as part of the military’s Holiday Airspace Release Plan. This effectively precludes launches around Thanksgiving, Christmas, and New Year’s Day due to the high volume of airline flights.

Ellis said the company is progressing well toward securing a launch license for “Good Luck Have Fun,” and noted that the Federal Aviation Administration accepted its methodology for debris mitigation as well as its trajectory analysis software.

The article at the link adds some additional details about the company’s plans. This Terran-1 rocket appears to be its equivalent of SpaceX’s Falcon-1. The company plans to quickly replace it with its much larger Terran-R rocket, comparable to the Falcon-9 in power and price. And it already has won $1.2 billion in launch contracts, and hopes to launch within two years.

I wonder if Terran-R will launch before Blue Origin’s much touted but repeatedly delayed New Glenn rocket. The article itself appears to think so, since it focuses entirely on the competition between SpaceX and Relativity, as if Blue Origin and New Glenn do not even exist.

ISS dodges space junk from Russia’s November 2021 anti-satellite test

9:46 am

In order for ISS to avoid one of the approximately 585 pieces of space junk still in orbit that were produced when Russia destroyed its defunct Cosmos 1408 satellite in a November 2021 anti-satellite test, engineers fired the engines of a docked Progress freighter yesterday for just over five minutes.

Without the burn the debris would have flown within three miles of the station, too close for comfort or anyone’s margin of error.

According to a report in September, of these 585 pieces, most will burn up in the atmosphere by ’25, with only 38 pieces left afterward to pose a threat to other operating satellites and manned spacecraft.
