  • On this day in 2018 InSight touched down on Mars
    Though the mission was able to do the first seismology on Mars, overall it was a troubled mission. It was delayed years because the first seismometer, built by France, didn’t work and had to be replaced, and then the second science instrument, a German-built drill designed to drill down five meters, failed to work on Mars.

Unusual light-colored Martian dunes

Unusual light-colored Martian dunes
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 27, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The picture was simply labeled a “terrain sample,” which usually means it was taken not as part of any specific research request, but to fill a gap in the schedule so as to maintain the camera’s proper temperature. When such gap-filler pictures are necessary, the MRO camera team tries to snap something of interest. Sometimes the pictures end up somewhat boring. This time however the picture highlights a dune field that is unusually light in color.

Since most Martian sand is volcanic in origin, it tends to look dark in orbital pictures. That this sand looks bright could be because it is inherently different, or it could be that lighting conditions make what normally looks dark to look bright instead.

Trump’s picks to run all the federal health agencies guarantees major change is coming

1:02 pm

Trump defiant after being shot
Trump defiant

Fight! Fight! Fight! The announcement late yesterday that president-elect Donald Trump has picked Jay Bhattacharya, the director of Stanford University’s Center for Demography and Economics of Health and Aging, to head the National Institutes of Health (NIH) underlined quite forcefully the certainty that the outsider nature of all of Trump’s picks to head all the health-related agencies in the federal government will led to major changes in how those agencies operate.

Bhattacharya had been blacklisted for his very vocal opposition to the government’s lockdown and mandate policies during the COVID epidemic. He along with Martin Kulldorff, one of the world’s foremost experts on vaccines and who was also blacklisted during the epidemic, co-authored the Great Barrington Declaration that strongly criticized the policies of imposed by these health agencies, calling instead for a return to the standard response to infectious diseases that had been followed successfully for more than a century.

Putting Bhattacharya in charge of NIH is incredibly ironic. When he along with Kulldorff had come out opposed to the lockdown and jab mandates advocated by Francis Collins, then-head of the NIH, Collins in league with Anthony Fauci, then head of National Institute of Allergy and Infectious Diseases (NIAID), put together a back-room campaign to have Bhattacharya, Kulldorff, and many others blacklisted across social media. This campaign also had Kulldorf removed as a member of the CDC’s vaccine safety advisory committee.

Two years later, Collins is now gone, is being sued for his actions, and Bhattacharya has replaced him.

Trump’s defiant choice of Bhattacharya however is only one of many similar decisions, beginning last month with the choice of Robert Kennedy Jr. to run the Department of Health and Human Services.

NASA: forcing it to fly VIPER would cause it to cancel funding to 1 to 4 other commercial lunar landers

10:31 am

VIPER's planned route on the Moon
VIPER’s now canceled planned route at the Moon’s south pole

According to a response by NASA to a House committee and obtained by Space News, if Congress forces the agency to fly its canceled VIPER moon rover NASA would have to cancel funding to one to four other commercial lunar landers being built by private companies as part of NASA’s CLPS program.

In one scenario, NASA assumed VIPER would launch on Astrobotic’s Griffin lander as previously planned in September 2025. The agency estimated it would need to spend $104 million to prepare VIPER itself, $20 million of which had already been allocated for activities in fiscal year 2024, along with $20 million in “additional risk mitigation activities” for Griffin. “NASA estimated that these additional funding requirements would lead to cancellation of one CLPS delivery and delay of another delivery by a year,” it stated.

A second scenario anticipated a one-year slip in VIPER’s launch to September 2026. NASA projected an additional $50 million in costs for VIPER and $40 million for Griffin. That would have resulted in two canceled CLPS task orders and a one-year delay to two others.

NASA also revealed it considered “alternative delivery means” for VIPER other than Griffin. NASA did not disclose details about those alternatives, calling them “highly proprietary” but which would have delayed the launch of VIPER beyond 2026 “and would still include significant uncertainty about the reliability of delivery success.” NASA projected total costs of $350 million to $550 million with this scenario, resulting in the cancellation of four CLPS task orders and delaying three to four more by two years.

NASA preferred option is for a private company to take over VIPER. At the moment the agency is reviewing eleven proposals put forth by such companies that has “enough spaceflight experience and technical abilities to conduct the VIPER mission.”

Congress has gotten involved because the science community has lobbied hard to save it. The project itself has been a problem for NASA since its first iteration as Resource Prospector, when NASA would have built both the rover and lander. It has consistently gone over budget and behind schedule, even after NASA gave the lander portion to a private company, Astrobotic. At present the rover is 3X over budget with more overages expected, which is why NASA cancelled it.

American spaceplane startup signs deal with Australian spaceport startup

10:17 am

Australian commercial spaceports
Australia’s commercial spaceports. Click for original map.

The American spaceplane startup Titans Space, which hopes to develop a reusuable space plane based on designs developed in the 1970s by Rockwell, has now signed a deal with the Australian spaceport startup Space Port Australia to work together to find an Australian location for both building the spaceplane and launching it.

Titans Space, a company that is taking an innovative approach to the space industry, has ambitious plans to become the largest low-earth orbit and lunar space tourism company in the world, as well as the largest “real estate owner in space and the Moon”.

Space Port Australia, which is headquartered in the NSW regional town of Moree, is committed to creating an integrated space facility which fosters innovation, industry, education and helps grow Australia’s place in the space sector.

Though Titans has raised some investment capital, this project is right now in its aspirational phase. It is very possible none of this will happen. This announcement is mostly an attempt to generate interest in both projects.

As for Space Port Australia, if it finds a location for this project it would be the fourth spaceport in Australia, joining the three spaceports that already have completed or have planned launches, as shown on the map to the right.

FCC approves use of Starlink for direct cell-to-satellite T-Mobile service

10:02 am

Despite objections from all of SpaceX’s competitors, the FCC has now approved the use of its Starlink constellation for direct cell-to-satellite service as part of T-Mobile’s cellular network.

The decision noted that many technical issues still must be cleared.

There are a few limitations on how this type of service (which the FCC calls “supplemental coverage from space,” or SCS) can work. Right now it officially has to operate as an extension of an existing terrestrial provider, in this case T-Mobile. That’s because the regulations on how you broadcast stuff in space are different from those for how you broadcast stuff to and from a phone (as opposed to a base station antenna). AT&T, for its part, is partnering with AST SpaceMobile.

SpaceX must also be sure that its service does not interfere with other services on the ground, while the ground services do not have to worry about whether they might interfere with the satellite signals.

Nonetheless, this approval likely means that soon users of T-Mobile (as well as AT&T) will no longer have any dead zones. When there are no cell towers available, their phones will simply access the orbiting constellations of either Starlink or AST SpaceMobile.

ESA flies suborbital rocket from Swedish spaceport

9:55 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The European Space Agency (ESA) yesterday successfully flew a small suborbital rocket from the Esrange spaceport in Sweden, completing the sixteenth such flight since 1987.

The rocket reached an altitude of 256 km before falling back to Earth and providing approximately six minutes of microgravity to six scientific experiments onboard.

…All systems performed well during the flight and the valuable payloads were recovered by helicopter soon after landing. Flight samples of the experiments will now be returned for further analysis to science teams from Sweden, Germany and Finland, after more than two years of preparations.

This suborbital launch is only a preliminary of much bigger things to come. The rocket startup Firefly is building a launchpad at Esrange for orbital launches. Furthermore, the European startup MaiaSpace, a subsidary of ArianeGroup, plans to do tests of its partly reusable Maia rocket there in 2025.

Judge dismisses lawsuit against SpaceX by activists

9:41 am

A federal judge has now thrown out a lawsuit that had been filed by anti-Musk activists in an attempt to halt all launches by SpaceX of its Starship/Superheavy rocket at Boca Chica.

U.S. District Judge Rolando Olvera issued his ruling last Thursday in response to the request filed by Save RGV on Oct. 9. The group has alleged that SpaceX’s water deluge system is releasing untreated industrial wastewater during launches and sought to halt the launches.

The water deluge system is designed to dampen the effects of Starship’s rocket engine blasts during liftoff and static fire engine testing.

“At the beginning of the Starship-Super Heavy Launch System’s development, it became evident that a deluge water system was necessary to protect the launch site and surrounding areas during launches,” Olvera wrote in the order. “A deluge water system sprays large quantities of potable water at the base of the spacecrafts during launch to prevent fires and reduce dispersal of dust and debris.

“Because of these dangers, Defendant cannot launch its spacecrafts without the deluge water system.”

SpaceX had argued that environmental reviews by both federal and state agencies had determined that the deluge system caused no harm. Olvera concurred, and also noted that to block launches would do significant harm to SpaceX and NASA’s entire lunar program.

This activist group, which represents almost no one in southern Texas, has no real interest in the environment. It filed this and other lawsuits simply as lawfare to try to stymie SpaceX for political reasons, knowing that we have more than seven decades of data at spaceports in Florida and California that prove rocket launches and deluge systems cause no environmental harm. In fact, they help wildlife by creating a large refuge where that wildlife can thrive.

Expect further similar lawsuits, all of which will be summarily dismissed afterward.

What I wonder is who is paying for this lawfare? SaveRGV likely doesn’t have the resources.

Engineers restore Voyager-1 after communications issue

9:20 am

The Voyager missions
The routes the Voyager spacecraft have
taken since launch.

Engineers have now manged to resume normal communications with the Voyager-1 interplanetary probe after it had shut down its main communications channel last month due to low power levels.

Earlier this month, the team reactivated the X-band transmitter and then resumed collecting data the week of Nov. 18 from the four operating science instruments. Now engineers are completing a few remaining tasks to return Voyager 1 to the state it was in before the issue arose, such as resetting the system that synchronizes its three onboard computers.

The X-band transmitter had been shut off by the spacecraft’s fault protection system when engineers activated a heater on the spacecraft. Historically, if the fault protection system sensed that the probe had too little power available, it would automatically turn off systems not essential for keeping the spacecraft flying in order to keep power flowing to the critical systems. But the probes have already turned off all nonessential systems except for the science instruments. So the fault protection system turned off the X-band transmitter and turned on the S-band transmitter, which uses less power.

The S-band transmitter had not been used since 1981, so it took awhile for ground engineers to find the very weak signal. Once found however it was possible to recover operations, though those operations will likely continue for only another year or two. The spacecraft’s power supply is expected to finally run out sometime in ’26 or ’27.

Two launches early today

9:11 am

China and SpaceX successfully completed launches early today.

First, the Chinese pseudo-company Landspace launched a new version of its Zhuque-2 methane-fueled rocket, lifting off from the Jiuquan spaceport in the northwest of China. The mission placed two test satellites into orbit, but more important, the launch tested the rocket’s new fuel-loading systems that copies SpaceX’s, loading the fuel quickly and cooling it to a lower temperature to increase its density and thus allow more to be packed into its tanks.

No word on where the rocket’s first stage crashed inside China.

SpaceX then placed 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida. The first stage completed its fifteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

122 SpaceX
55 China
14 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 141 to 82, while SpaceX by itself leads the entire world, including American companies, 122 to 101.

Etched terrain on Mars

Etched terrain on Mars
Click for original image.

Today’s cool image is another example of what I call a “What the heck!” image. The picture to the right, simply cropped to post here, was taken on September 22, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It shows what the scientists label as “etched terrain,” an incredibly twisted and eroded landscape that to me actually defies description. In trying to research what scientists have learned and theorized about this terrain, it appears they think it is material that flowed over older terrain (thus its lack of many craters) that was subsequently eroded by later processes.

Why it eroded so strangely however is not really understood. It could have been caused by near-surface ice sublimated to the surface and thus causing many breaks, but since this terrain is located right on the equator in the dry tropics, it is a very long time since water was present here.

Hubble vs Webb, or why the universe’s secrets can only be uncovered by looking at things in many wavelengths

11:15 am

Hubble view of Sombrero galaxy
Click for original image.

Time for two cool images of the same galaxy! The picture above shows the Sombrero Galaxy as taken by the Hubble Space Telescope in 2003. The picture below is that same galaxy as seen by the Webb Space Telescope in the mid-infrared using false colors. From the press release:

In Webb’s mid-infrared view of the Sombrero galaxy, also known as Messier 104 (M104), the signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is revealed. The sharp resolution of Webb’s MIRI (Mid-Infrared Instrument) also brings into focus details of the galaxy’s outer ring, providing insights into how the dust, an essential building block for astronomical objects in the universe, is distributed. The galaxy’s outer ring, which appeared smooth like a blanket in imaging from NASA’s retired Spitzer Space Telescope, shows intricate clumps in the infrared for the first time.

Researchers say the clumpy nature of the dust, where MIRI detects carbon-containing molecules called polycyclic aromatic hydrocarbons, can indicate the presence of young star-forming regions. However, unlike some galaxies studied with Webb … the Sombrero galaxy is not a particular hotbed of star formation. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year. Even the supermassive black hole, also known as an active galactic nucleus, at the center of the Sombrero galaxy is rather docile, even at a hefty 9-billion-solar masses. It’s classified as a low luminosity active galactic nucleus, slowly snacking on infalling material from the galaxy, while sending off a bright, relatively small, jet.

In infrared the galaxy’s middle bulge of stars practically vanishes, exposing the weak star-forming regions along galaxy’s disk.

Both images illustrate the challenge the universe presents us in understanding it. Basic facts are often and in fact almost always not evident to the naked eye. We always need to look deeper, in ways that at first do not seem obvious. This is why it is always dangerous to theorize with certainty any explanation too soon, as later data will always change that explanation. You can come up with an hypothesis, but you should always add the caveat that you really don’t know.

By the way, this concept applies not just to science. Having absolute certainty in anything will almost always cause you to look like a fool later. Better to always question yourself, because that will make it easier for you to find a better answer, sooner.

We need only look at the idiotic “mainstream press” during the months leading up to the November election to have an example of someone with certainty who is now exposed as an obvious fool.

Firefly’s Blue Ghost lunar lander now targeting mid-January launch window

10:08 am

Landing sites on Moon

According to a media update from NASA yesterday, Firefly’s Blue Ghost lunar lander now targeting mid-January launch window for its unmanned mission to the Moon.

A six-day launch window opens no earlier than mid-January 2025 for the first Firefly Aerospace launch to the lunar surface.

The Blue Ghost flight, carrying 10 NASA science and technology instruments, will launch on a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Media prelaunch and launch activities will take place at NASA Kennedy.

The first quarter of 2025 will be a busy time for unmanned missions to the Moon. In addition to Firefly’s mission, the American startup Intuitive Machines also hopes to launch its Athena lander to the Moon’s south pole in February. Though it will launch after Blue Ghost, it will get to the Moon first, as it is taking a more direct week-long route compared to Blue Ghost’s 45-day journey. In addition, the Japanese company Ispace is targeting its own January launch for its Resilience lander.

If all three lift off as planned, there will be three landers heading for the Moon in early 2025.

Engine for Japan’s new Epsilon-S rocket explodes during static fire test

9:36 am

For the second time in a row an engine for Japan’s new Epsilon-S rocket has exploded during a static fire test.

The test was conducted inside of the restricted area at Japan’s Tanegashima Space Center in southwestern Japan, and the Japan Aerospace Exploration Agency is investigating, Chief Cabinet Secretary Yoshimasa Hayashi told reporters.

An Epsilon project manager, Takayuki Imoto, told an online press conference from Tanegashina that the explosion occurred 49 seconds into the planned two-minute test, causing fire and scattering broken parts of the engine and damaging the facility.

The Epsilon-S is being built by Japan’s space agency JAXA. It is intended to replace the solid-fueled Epsilon rocket that was initially conceived in 2013 to lower launch costs and provide JAXA with a rocket that could complete with the many new smallsat rocket startups worldwide. That rocket however only launched six times and never achieved its goals. JAXA had been targeting March for the first launch of Epsilon-S, but that is now unlikely, especially considering these two engine failures during tests.

France to resume suborbital launches at French Guiana

9:14 am

Now that France’s space agency CNES has taken the management of its French Guiana spaceport back from the European Space Agency’s Arianespace government company, it has been moving to make the spaceport more attractive to multiple future launch customers. Previously it announced that it is offering launchpads to multiple new rocket startups. Now it has announced that has signed a contract with the French startup Optus Aerospace to reopen its closed suborbital launchpad for the first time in decades.

Officially inaugurated in 1968, the Ensemble de Lancement Fusées-Sondes (ELFS) launch complex hosted the Guiana Space Centre’s first launch on 9 April 1968, with a Véronique sounding rocket that reached an altitude of 113 kilometres. Between 1968 and 1992, more than 350 sounding rockets were launched from the facility.

On 25 November, CNES announced that it had signed a contract with Opus Aerospace to use the ELFS facility for the launch of its Mésange rocket.

In other words, under the control of a government entity, Arianespace, which also controlled all European launches for decades, the variety of launches declined. As soon as control was lifted from this government monopoly however the possibilities expanded quickly.

SpaceX wins launch contract for Dragonfly mission to Titan

8:58 am

NASA yesterday announced that it has awarded the launch contract for sending its Dragonfly mission to Titan to SpaceX’s Falcon Heavy rocket.

The firm-fixed-price contract has a value of approximately $256.6 million, which includes launch services and other mission related costs. The Dragonfly mission currently has a targeted launch period from July 5, 2028, to July 25, 2028, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Dragonfly is a truly cutting edge mission. Though we have relatively limited information about Titan’s atmosphere and the environment on its surface, it will attempt to fly there like a helicopter, landing and taking off multiple times.

And though there are certainly additional costs required for such a mission, that quarter-billion dollar contract price probably triples what it normally costs SpaceX for a Falcon Heavy mission. Even if it requires the expending of all three first stages, the company is almost certainly getting a big windfall from this deal.

Martian mountains amidst a deep sea of sand

Overview

A Martian mountain surrounded by a sea of sand
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 9, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The white dot on the overview map above marks the location, inside the deep enclosed and very large 130-mile-wide depression dubbed Juventae Chasma.

The mountain in the picture raises above the sand sea that surrounds it from 1,000 to 2,300 feet, depending on direction, as the downhill grade of the sand sea is to the east. Thus, on the west the mountain rises less, while on the east the height is the greatest.

The inset illustrates the extent of the sand sea. It covers the ground for many miles in all directions. The way the sand surrounds these mountains suggests the prevailing winds blow from the west to the east. In fact, the facts suggest that this sand is volcanic ash that was blown into Juventae from many eruptions that occurred over time to the west, where it got trapped. The wind and gravity deposited the sand into the 20,000 to 25,000-foot-deep chasm, where the wind was insufficient to lift it out again.

One wonders how deep that sand sea might be. The lack of any surface features at all suggests it could be quite deep, burying everything but the highest peaks. In fact, if a geologist could drill a core through that sand I suspect he or she might be able to document the entire eruption history of much of Mars.

Italy to resume use of its San Marco spaceport off the coast of Kenya

9:21 am

Italy's offshore San Marco spaceport
Click for full map.

Italy has now decided to re-open its long unused San Marco spaceport facility off the coast of Kenya, resuming launches from its off-shore launch platform.

During its active life beginning in 1967 a total of eight launches occurred from this site, with the last flight occurring in 1988.

In late 2023, the Minister of Enterprise and Made in Italy, Adolfo Urso, first proposed reopening the facility for rocket launches. While unsubstantiated by other sources, local publication MalindiKenya.net reported at the time that the move would be used to create an “ideal launch base for the Italian Vega launcher, thus avoiding paying France for the use of the French Guiana base.”

In October 2024, during a presentation just before the 75th International Astronautical Congress kicked off, Minister Urso explained that the country had decided to move ahead with its plans to once again launch rockets from the Luigi Broglio Space Center.

The present plans will have the site managed by the Kenya Space Agency, established in 2017, with Italy providing the rockets and satellites, all of which are expected to be smallsats. It appears that the rocket company Avio, which builds the Vega-C rocket, might be aiming to use this site as an commercial launchpad, thus allowing it to bypass the French-run French Guiana spaceport. Located close to the equator and on the coast, this site would offer satellite companies a very wide range of orbits.

Launches galore in the past twelve hours

8:49 am

The past twelve hours was quite busy at spaceports worldwide, with two American companies completing three different launches from three different spaceports, while China added one of its own.

First China launched two radar-mapping satellites, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China. No word on where its lower stages, that use very toxic hypergolic fuels, crashed inside China. Though this launch was first, it actually took place in the early morning of November 25th, in China.

Next, Rocket Lab completed two launches, though one was not an orbital flight. First it completed its second of four planned launches of its HASTE suborbital version of its Electron rocket, lifting off from Wallops Island in Virgina. HASTE had been quickly improvised by the company when it realized there was a real market for hypersonic suborbital testing, and Electron could be refitted for that purpose. This launch actually occurred prior to the Chinese launch.

Then Rocket Lab launched five more satellites for the satellite company Kineis, the third of five, its Electron rocket lifting off from one of its two launchpads in New Zealand.

Finally, SpaceX in the early morning of November 25th launched 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its thirteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

121 SpaceX
54 China
14 Russia
13 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 140 to 81, while SpaceX by itself leads the entire world, including American companies, 121 to 100.

Unloading of new Progress docked to ISS delayed due to “toxic smell”

10:02 pm

The unloading of cargo from the new Progress freighter that docked to ISS on November 23, 2024 halted immediately after hatch opening because of a “toxic smell” detected by the Russian astronauts.

The crew then proceeded with air leak checks in the docking port, but after opening the hatch between Poisk and Progress, it had to be closed immediately due to toxic smell and possible contamination hazard in the form of droplets, according to communications between the US mission control in Houston and the ISS crew in late hours Moscow Time on November 23.

Various systems aboard the ISS were activated to scrub the station’s atmosphere from possible contamination, while the hatch of the Poisk module leading into the pressurized cargo compartment of the Progress M-29 spacecraft remained closed. In particular, the Trace Contaminant Control Sub-assembly, TCCS, was turned on aboard the US Segment. The Russian crew was also reported donning protective equipment and activating an extra air-scrubbing system aboard the Russian Segment, which operated up to a half an hour.

By the end of today mission controllers from both Russian and the U.S. declared the air cleared and normal, and have begun unloading operations.

The cause remains unexplained.

New Glenn on the launchpad and vertical for the first time

The first completely assembled New Glenn, on the launchpad
The first completely assembled New Glenn,
on the launchpad

Blue Origin’s first New Glenn rocket to be fully stacked and ready for launch was finally placed vertical on its Cape Canaveral launchpad late November 21, 2024.

For the first time, the company placed a fully integrated, flight-capable rocket on the launch pad Thursday evening. The company rolled the rocket out of the hangar at Launch Complex 36 (LC-36) earlier. A static fire test with the full 98-meter-tall (320 ft) rocket is forthcoming, though a specific date hasn’t been announced.

…The upcoming integrated static fire test would be the first time that Blue Origin fuels a full-assembled. flight-ready New Glenn rocket. It previously conducted a static fire test of its upper stage, which saw a 15-second burn of the two BE-3U engines.

The picture to the right was released by the company that night.

No launch date has been announced. The present payload for this launch is the company’s own Blue Ring orbital tug on a Pentagon-supported test flight. The original payload, two smallsat NASA Mars orbiters built by Rocket Lab, had to be pulled when Blue Origin’s generally leisurely approach meant that it was unable to get the rocket ready in time to meet the October launch window.

That leisurely approach to business will have to end if Blue Origin really wants to compete in today’s modern aerospace industry.

Distinct gully draining the side of a Martian crater

Distinct gully in crater on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 20, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labels the entire picture simply as “gully,” obviously referring to that distinct and somewhat deep hollow in the middle of the picture.

Most gullies that have been found on Mars tend to look more eroded and rougher than this hollow. Here, it appears almost as if the process that caused this gully occurred relatively recently, resulting in its sharp borders that have not had time to crumble into softer shapes.

The crater interior slope is about 1,500 feet high. Whatever flowed down it however did not do it in an entirely expected manner. As it flowed it curved to the west, so that the impingement into the glacial material that fills the crater floor is to the west of the gully itself. Either that, or that impingement was caused by a different event at a different earlier time.

Starship gets contract to deliver Lunar Outpost’s rover to Moon

11:10 am

Capitalism in space: The lunar lander version of SpaceX’s Starship has won a contract from the startup Lunar Outpost to deliver its manned rover to the Moon.

The Colorado company announced Nov. 21 that it signed an agreement for SpaceX to use Starship to transport the company’s Lunar Outpost Eagle rover to the moon. The companies did not disclose a schedule for the launch or other terms of the deal.

This announcement is less a new deal for SpaceX and more an effort to convince NASA to award Lunar Outpost the full contract to build the rover. In April 2024 Lunar Outpost was one of three companies chosen by NASA to receive initial development grants to design their proposed manned lunar rovers. NASA expects to award the full contract, worth potentially up to $4.6 billion, to one of these three companies later this year, after seeing their preliminary designs. It wants to choose two, but at present says budget limitations make that impossible.
