A cliff of ice on Mars

12:56 pm

A cliff of ice on Mars
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on April 10, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the southern nose of a large plateau located in the deep south of Mars, at 63 degrees south latitude. This cliff is only about 20-25 feet high, but within that small distance orbital imagery as revealed what appears to be an underground layer of ice. When this photo was released in late June, it came with a short caption, which noted:

On these steep scarps, ice can still be seen on the south facing walls of the scarp towards the end of the Southern Hemisphere’s winter.

Note the white sections on that cliff wall, both inside and outside the color strip. The surrounding orange suggests dust and sand. This photo suggests that during the dark winter underground ice leaches out on these slopes, and is then sublimated away when the Sun returns in the spring. Since the south-facing walls remain in shadow the longest, the ice there lasts the longest, leaving behind these patches we see now.

It is also possible that this is not water ice and there is no underground ice layer. Instead, this might be the last leftover of the dry ice mantle that falls as snow and covers all of the Martian high latitudes during the winter, and then sublimates away come spring.

The battle between a Brazil judge and Starlink/X escalates

9:55 am

After Brazil’s Supreme Federal Court (STF) Justice Alexandre De Moraes froze Starlink bank accounts in Brazil in order to guarantee payments of fines he imposed on X because it refused to obey his commmand to censor some users, Elon Musk has responded defiantly and with force.

Starlink said Thursday that it will challenge De Moraes’ decision regarding the company’s bank accounts. “The order is based on an unfounded determination that Starlink is liable for the fines levied against X. It was issued in secret and without giving Starlink any of the due process guaranteed by the Brazilian Constitution. We intend to address the matter legally,” the company argued.

De Moraes’ deadline to appoint a new legal representative of X ended at 8.07 pm Thursday and, as expected, it was not complied with. In this scenario, the next step would be to suspend the social network in the country, for which there is still no deadline. X said in a statement that it would not comply with the judge’s “illegal decisions” aimed at “censoring“ De Moraes’ ”political opponents.”

“When we tried to defend ourselves in court, the minister threatened to arrest our legal representative in Brazil. Even after his resignation, he froze all his bank accounts. Our challenges against his manifestly illegal actions were rejected or ignored. Minister Alexandre De Moraes’ colleagues on the Supreme Court are either unable or unwilling to confront him,” X underlined while announcing it would be disclosing the judge’s confidential decisions against the company. X “does not comply with illegal orders in secret,” the company stressed.

“We are absolutely not insisting that other countries have the same free speech laws as the United States. The fundamental issue at stake here is that Justice Alexandre De Moraes is demanding that we violate Brazil’s own laws. We simply won’t do that,” the company added.

Musk has also pointed out that Starlink is an entirely different company than X. Musk has said that since its bank accounts are presently frozen, it will provide its users service for free, since “Many remote schools and hospitals depend on SpaceX’s Starlink.” He however soon expects De Moraes to shut down this service soon as well. He has also called De Moraes an “”an outright criminal” whom he expects to end up behind bars someday for his censorious and illegal rulings.

NASA names revised crew for next manned Dragon mission to ISS

9:34 am

NASA today named the two astronauts who will fly on the next manned Dragon mission to ISS, to be launched on September 24, 2024 for a six month mission, where they will be joined by the two astronauts who launched on Boeing’s Starliner in June but now will return with them when their Freedom capsule returns in February 2025.

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman and Stephanie Wilson, previously announced as crewmates, are eligible for reassignment on a future mission. Hague and Gorbunov will fly to the space station as commander and mission specialist, respectively, as part of a two-crew member flight aboard a SpaceX Dragon.

The updated crew complement follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed and launch Crew-9 with two unoccupied seats. NASA astronauts Butch Wilmore and Suni Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.

With Starliner now scheduled to return on September 6th and Freedom not arriving until around September 24th, there will be an eighteen day period when Wilmore and Williams will have a limited and more risky lifeboat option on ISS. If an incident should occur that requires station evacuation there is room to squeeze them inside SpaceX’s Endeavour Dragon capsule presently docked there, but they will return without flight suits. Their Dragon flight suits will not arrive until September 24th, on the next Dragon. The suits they used on Starliner will not work on Dragon.

First New Glenn launch, set for October 13, 2024, only has an 8-day launch window

9:16 am

According to an article from Aviation Week today, in order for Blue Origin’s New Glenn rocket to get its payload of two Mars orbiters on their way to Mars it must launch within a very short window lasting only eight days, beginning on the present launch date of October 13, 2024.

The Oct. 13-21 launch window is an ambitious goal. The aft and mid modules of New Glenn’s reusable first stage were recently attached, clearing the path for installation of the vehicle’s seven methane-fueled BE-4 engines, CEO Dave Limp noted in an Aug. 23 update on the X social media site.

A static hot-fire at New Glenn’s Florida launch complex is planned prior to launch. The company did not release the status of the New Glenn upper stage, which is to be powered by a pair of BE-3U engines fueled by liquid oxygen and liquid hydrogen. A hot-fire of the second stage is also pending.

This launch will be the first ever for New Glenn. To get ready for that tight launch window it appears a great deal of work must be done in the next six weeks, some of which Blue Origin engineers will be doing for the very first time.

If there are any issues and that launch window is missed, the two NASA Escapade orbiters, built by Rocket Lab, will face a two-year delay until the next window to get to Mars re-opens. At that point New Glenn will likely do this launch with a dummy payload, since it needs to get off the ground in order to fulfill other launch contracts, including a 27-launch contract with Amazon for its Kuiper satellite constellation.

NASA solar sail successfully deploys

9:03 am

After experiencing a technical issue that initially delayed deployment, NASA engineers have now successfully deployed the boom of the 860-square-foot solar sail that had been launched in a cubesat only about four feet in size.

NASA’s Advanced Composite Solar Sail System is now fully deployed in space after a successful test of its sail-hoisting boom system. Mission operators confirmed success at 1:33 p.m. EDT (10:33 a.m. PDT) on Thursday, Aug. 29, after receiving data from the spacecraft. Centrally located aboard the spacecraft are four cameras which captured a panoramic view of the reflective sail and supporting composite booms. High-resolution imagery from these cameras will be available on Wednesday, Sept. 4.

The next step will be to test the sail’s ability to maneuver in space, including raising and lowering its orbit using the pressure of sunlight, just like sailboats use the wind.

NASA awards Intuitive Machines a new lunar lander contract

8:55 am

NASA yesterday announced that it has awarded Intuitive Machines a new lunar lander contract for $116.9 million to carry six NASA/ESA payloads to the surface of the Moon.

The announcement stated that the landing will be in the south pole region of the Moon, but did not reveal the specific location. Of the six science packages, the most important is a European Space Agency-led drill that will obtain samples from as much as three feet down and then analyze them.

The contract calls for a 2027 landing, and will be the fourth targeting the south pole region, following Intuitive Machines first attempted landing there early this year that landed but then tipped over, preventing its science instruments from functioning as planned.

Starliner to return unmanned on September 6

8:44 am

NASA today announced that Starliner will undock from ISS on September 6, 2024 at about 6:00 PM (Eastern) and will then land six hours later at White Sands in New Mexico.

The announcement touts Starliner’s ability to fly autonomously, but based on what we know this is really not something to brag about. All Dragons do this routinely whether they are manned or not. Starliner required an upload of software to reconfirgure it for this, since it had originally been configured for a manned return and apparently that original software was not designed for an unmanned return.

In other words, the spacecraft as presently designed doesn’t have the ability to switch from autonomous to manned in a simple manner.

August 29, 2024 Quick space link

3:17 pm

BtB’s stringer Jay had no quick link stories today, but I thought for completion’s sake I should include this one from yesterday:

  • Blue Origin’s New Shepard yesterday completed its 8th manned suborbital flight

    • Not much else to say. These suborbital flights are nice, but they no longer represent the future, only the past. The future will be illustrated by Polaris Dawn, SpaceX’s next manned commercial orbital flight, scheduled to take off sometime in the next week or so, depending on weather and the FAA’s intransigence.

Monument rally on January 6, 2021.

Fight! Fight! Fight! Jason Moorehead, who was fired for being in Washington on January 6, 2021 to attend a Trump rally at the Washington Monument (never getting within a mile of the Capitol and thus never participating in any way with any violent events there), has now won a wrongful termination suit from the Pennsylvania Allentown School District as well as two school board members.

On Aug. 16, a jury awarded Moorehead $131,500, most of which will come from the district. Two school board members, Lisa Conover and Nancy Wilt, are liable for $6,000 and $500 respectively. Moorehead had not specified a desired dollar amount for “loss of earnings, loss of career, reputational damage, mental and emotional pain and suffering,” and punitive damages.

Moorehead’s lawyer AJ Fleuhr said in statement that he and his client were happy “a federal jury recognized that the Allentown School District violated Jason Moorehead’s First Amendment rights to free speech, assembly, and political affiliation,” and that the named board members had “maliciously and wantonly attacked him.”
