Stratolaunch yesterday successfully flew its giant Roc airplane with a Talon hypersonic engineering vehicle attached for the first time to its central fuselage.

The flight lasted just over five hours, reached an altitude of 23,000 feet, and was “focused on measuring the aerodynamic loads on the Talon-A vehicle while mated to Roc. The loads captured in flight will validate aerodynamic predictions to ensure the release mechanism will function as designed.”

The company will complete a series of captive carry flights in the coming months, culminating in a separation test of the TA-0 vehicle out over the Pacific Ocean in late 2022.

Even as these flight tests proceed, the company is building the actual Talon flight vehicles, designed as testbeds for doing hypersonic flight tests quickly and relatively cheaply. The plan is to have these flight vehicles ready for both military and commercial customers to fly them by ’23.

NASA & ESA pick site for Perseverance to deposit its samples for pickup

Overview map
Click for interactive map.

Engineers at NASA and the European Space Agency (ESA) have now chosen the site in Jezero Crater where Perseverance will deposit its first set of core samples for later pickup by a mission to bring them back to Earth.

The location, at the base of the delta that flows into the crater and indicated by the white cross on the map to the right, will contain all the core samples collected from the floor of the crater. This area, in the middle of the flat region the science team has dubbed Three Forks, provides a good landing place for the sample return helicopter that will fly from point to point to pick these samples up. The blue dot on the map indicates Perseverance’s present position. The green dot where the helicopter Ingenuity presently sits.

Once the rover has finished collecting samples and doing its research at the base of the delta, it will deposit those samples at this point and then move up onto the delta, where it will collect more samples that will be placed at a different spot for pickup.

NASA sets new launch date for Psyche asteroid mission

NASA yesterday announced that the delayed Psyche mission, to the asteroid Psyche, now has a new launch date of October 10, 2023, with a planned arrival in 2029.

The spacecraft missed its original launch date in 2022 because of the late delivery of its flight software combined with problems with the equipment needed to test that software.

The new launch date, though only one year later than planned, will cause the spacecraft to arrive two years late because of orbital mechanics.

InSight detects and dates large impact on Mars

InSight's Christmas Eve impact
Click for full image.

Using the data from InSight’s seismometer of a 4 magnitude earthquake on Mars on December 24, 2021, scientists were able to use the high resolution camera on Mars Reconnaissance Orbiter (MRO) to find the meteorite impact that produced that quake, the largest detected since spacecraft have been visiting Mars. The picture to the right, cropped and reduced to post here and unveiled at yesterday’s press conference, shows the new crater.

The meteoroid is estimated to have spanned 16 to 39 feet (5 to 12 meters) โ€“ small enough that it would have burned up in Earthโ€™s atmosphere, but not in Marsโ€™ thin atmosphere, which is just 1% as dense as our planetโ€™s. The impact, in a region called Amazonis Planitia, blasted a crater roughly 492 feet (150 meters) across and 70 feet (21 meters) deep. Some of the ejecta thrown by the impact flew as far as 23 miles (37 kilometers) away.

With images and seismic data documenting the event, this is believed to be one of the largest craters ever witnessed forming any place in the solar system.

This is not the first such impact identified from InSight seismic data, but it is the largest. The white streaks surrounding the crater are thought to be near-surface ice ejected at impact.

The overview map below provides further context, as well as showing us the proximity of this impact to the proposed Starship landing sites on Mars.

ULA breaks ground on new facility in Alabama

ULA yesterday broke ground on the construction of a new facility in Alabama, where it will store its Vulcan rockets and build the fairings for that rocket.

The factory is scheduled to begin operations in 2024. According to ULA’S CEO, Tori Bruno, the facility will double the production rate for making Vulcan rockets, necessary to provide the launches that Amazon wants for its Kuiper internet constellation.

SpaceX successfully launches another 53 Starlink satellites

SpaceX tonight successfully used its Falcon 9 rocket to launch another 53 Starlink satellites into orbit, lifting off from Vandenberg Space Force Base in California.

The first stage completed its eighth flight, landing successfully on a drone ship in the Pacific. As of this writing, the satellites have not yet deployed, though they are in their planned orbit.

The leaders in the 2022 launch race:

49 SpaceX
45 China
18 Russia
8 Rocket Lab
7 ULA

American private enterprise now leads China 69 to 45 in the national rankings, though it trails the rest of the world combined 72 to 69. At 69 successful launches, the U.S. is now just one launch behind its national record of 70 set in 1966.

A glacier sea on Mars

A glacier sea on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, should at first glance be one of my “What the heck!?” images. However, a little detective work quickly provides us some understanding of the inexplicable geology seen at this particular location on Mars.

The picture was taken on August 29, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and was labeled by the science team a “Lobate Debris Apron in Deuteronilus Mensae.” This mensae region is the western part of the 2,000-mile-long strip in the northern mid-latitudes of Mars that I label glacier country, since almost every high resolution picture taken in this strip shows extensive glacial features.

This picture is no different, showing what appears to be glaciers, but by itself it is still difficult to make sense of it. Glaciers flow downhill, like rivers. In this high resolution image the direction of flow is somewhat unclear.

As always, a wider view clarifies the picture.

Russian government okays ISS partnership through ’27

The Russian government yesterday approved an order allowing Roscosmos to continue to send its astronauts and spacecraft to ISS through 2027.

“The expected results are as follows: transport and technical support for the Russian segment of the International Space Station in 2023-2027, including the delivery to the station and return to Earth of Russian crews, as well as the delivery to the ISS of fuel and cargo crucial to maintaining the ISS in flight and the implementation of a long-term program for authorized works,” the instruction says.

Putin’s government is essentially admitting that it will not be able to launch its own space station by ’27, so it has to stay on ISS because that’s all it has. Whether ISS can last that long, considering the somewhat delicate state of some of the oldest Russian modules, remains unclear.

The American private stations should all be coming on line in the years from 2024 to 2030, so it appears the U.S. is covered. What Russia will do however remains unknown. I suspect it will be far more difficult politically for it to buy time on the American private stations, compared to Europe. But if it doesn’t get its own station launched, buying time might be its only option, assuming of course the U.S. government allows it to do so. And considering that other Russian officials are threatening America’s private space assets, the likelihood that Russia will be allowed on future American space stations seems remote indeed.

European nations struggle with the new private commercial space station concept

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. โ€œWe need to find a new way of cooperating,โ€ 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. โ€œWe need to put on the table every option.โ€

The simplest approach โ€” direct payments from space agencies to the companies operating commercial stations โ€” could face political obstacles. โ€œThe taxpayers in Europe donโ€™t want to pay directly to private American companies,โ€ 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

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

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.
