NASA shuts down Goddard $2 billion demo refueling program

3:43 pm

After more than a decade of work and more than $1 billion spent, NASA yesterday shut down a Goddard Space Flight Center program, dubbed On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1), that would have attempted to refuel a defunct the Landsat-7 satellite.

This Space News article details the program’s long history:

OSAM-1 started about a decade ago as Restore-L, with the goal of launching as soon as 2020 to refuel Landsat 7. The mission was renamed OSAM-1 in 2020 with the addition of payloads to perform in-space assembly and manufacturing activities.

The mission, though, suffered significant cost overruns and delays. As of April 2022, the mission’s total cost, once projected to be between $626 million and $753 million, had grown to $2.05 billion and its launch delayed to December 2026. NASA’s Office of Inspector General (OIG), in an October 2023 report, concluded the project would likely suffer additional overruns, with an estimated cost at completion as high as $2.17 billion and a launch of between March and June 2027.

The program was originally conceived by Frank “Cepi” Cepollina, who had run the program in the 1980s to use the shuttle and standard parts on satellites to successfully repair the Solar Max satellite, and then headed the program at Goddard that ran all the repair missions to the Hubble Space Telescope. It was his correct contention that designing satellites and spacecraft with standard modular parts would not only allow for replacement and repair, it would reduce the cost of getting into space while increasing increasing profit margins.

The problem was that Cepi’s operation was a government program, divorced from cost controls and profit. Unlike the many private orbital tug companies that are now building and flying the same technology, developed quickly and for relatively little, the Goddard program experienced endless delays and cost overruns. In the end, private enterprise has overtaken the government, and made this program superfluous. Kudos to NASA’s management for making the hard decision to shut it down finally.

Time for one last cool image of Ingenuity. The picture above, cropped, reduced, and annotated to post here, was created from a mosaic of 67 images taken on February 21, 2024 by the high resolution camera on the Mars rover Perseverance. The white rectangle marks the approximate area covered by the image below, a mosaic of seven pictures taken on February 24, 2024 by Perseverance’s Remote Microscopic Imager camera, normally used to take very close images of nearby rocks but repurposed here to provide a close up of Ingenuity about 1,365 feet away, inside Neretva Vallis. Ingenuity is on the right, and the speck on the left is the section of the rotor blade that broke off and was apparently flung about 49 feet away.

On the overview map to the right, the blue dot marks Perseverance’s position, the green dot Ingenuity’s, and the yellow lines mark the approximate area covered by the panorama above. The red dotted line is Perseverance’s planned route in the coming months.

Astronomers discover new moons around Neptune and Uranus

8:50 am

Using a observations over several years from a number of ground-based telescopes, astronomers have now identified two new moons around Neptune and one new moon circling Uranus.

The new Uranian member brings the ice giant planet’s total moon count to 28. At only 8 kilometers, it is probably the smallest of Uranus’ moons. It takes 680 days to orbit the planet. Provisionally named S/2023 U1, the new moon will eventually be named after a character from a Shakespeare play, in keeping with the naming conventions for outer Uranian satellites.

…The brighter Neptune moon now has a provisional designation S/2002 N5, is about 23 kilometers in size, and takes almost 9 years to orbit the ice giant. The fainter Neptune moon has a provisional designation S/2021 N1 and is about 14 kilometers with an orbit of almost 27 years. They will both receive permanent names based on the 50 Nereid sea goddesses in Greek mythology.

The two new Neptune moons raises its moon total now to sixteen. The orbits of all three are tilted and eccentric and far from the planets, strongly suggested they are capture asteroids, not objects formed at the same time as the planet.

Local county now in full support of SpaceX land swap

8:41 am

According to a local Cameron county judge, who had previously expressed opposition, county officials including himself are now in full support of the proposed land swap, giving SpaceX 43 acres of Boca Chica State Park land in exchange for 477 acres at a national wildlife area about 10 miles away.

A special meeting of the Texas Parks and Wildlife Commission to vote on this land swap is now scheduled for March 5, 2024 in Austin, and it appears it is ready to approve. That meeting however should be entertaining, because it also appears that the small minority of leftist activists organizations in the area that oppose everything SpaceX is achieving are organizing carpools to attend the meeting. Expect them to perform the typical shennigans of the left, screaming and shouting and attempting to take over the venue to prevent the vote.

What these activists of course refuse to recognize, or simply don’t care, is that the change of opinion by local officials is because the local community and in fact the majority of Texans support what SpaceX is doing. It has revitalized the Brownsville area, bringing billions of new investment capital and tens of thousands of new jobs to the region. It has also demonstrated repeatedly it is being a good steward to the environment at Boca Chica, and will do much as a launch site to help preserve the coastal wildlife there, just as NASA has done at Cape Canaveral for three quarters of a century.

SpaceX and China complete launches

10:40 pm

Two successful launches today, first from China and then from SpaceX.

First, China launched what it called a”high-orbit internet services” satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No word where the rocket’s four strap-on boosters or core stage crashed in China.

Then SpaceX launched another 23 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

19 SpaceX
10 China
3 Russia

American private enterprise still leads the entire world combined 22 to 19 in successful launches, while SpaceX remains tied 19-19 with the rest of the world, excluding American companies.

Marilyn Monroe – Happy Birthday/Thanks For The Memories

6:01 pm

An evening pause: Another bit of cultural history from the 1960s. From the Youtube webpage:

Marilyn footage singing to JFK on his gala birthday bash on May 19th 1962. The running joke for the evening, as planned, was that Marilyn was late! it was planned that way for the event. Everything we see Marilyn do on stage was rehearsed right down to her arm movements and jumping up and down at the end of the song as we can see in the rehearsal photos before the event. so Marilyn did this spot on as planned.

Sadly, she would be dead by August, and Kennedy by November of the next year.

Hat tip Judd Clark.

Today’s blacklisted American: Event by UC-Berkeley Jewish organizations is shut down by violent pro-Hamas rioters

They’re coming for you next: A lecture on international law by an Israeli attorney and former member of the Israeli Defense Force and organized by Jewish student groups at University of California-Berkeley (UC-Berkeley) was shut down on February 26, 2024 by a violent protest of about 200 pro-Hamas rioters, who broke down doors, attacked attendees, and forced the university to evacuate and cancel the event.

Jewish students at UC Berkeley evacuated from a campus theater Monday night after a mass of protesters, chanting “Intifada! Intifada!” and other slogans, shattered a glass door at the venue and shut down a scheduled lecture by an Israeli attorney who is also an IDF reservist.

Several students who were attending or working the event at Zellerbach Playhouse were injured, including two young women, one of whom sprained a thumb wrestling to keep a door shut as protesters tried to muscle it open. Another female student reportedly was handled around her neck, leaving marks. A third student said a protester spit on him.

Eventually the lecture did take place, at the home of a nearby rabbi, but was only seen by twenty.

A Martian cliff of ash, flushed by wind

A Martian cliff of ash flushed by wind
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on December 27, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Described merely as an “exposed scarp” by the science team, this cliff edge is actually much more.

First some basic details. The elevation drop from the plateau down to the base of this cliff is about a thousand feet. The material that forms this plateau, scarp, and its base is all volcanic ash. The thicker sections of ash has caused its lower levels to compress, harden into a kind of sandstone. Near the surface however it is more friable, and like sandstone can break apart somewhat more easily.

The prevailing winds at this site are generally blowing to the south, but beginning to turn to the east, which explains the northwest to southeast orientation of the features.

The best analogy I can come up with to explain the erosion of this scarp is as follows: Imagine a deposit of dry mud a few inches thick on pavement. Take a leaf blower and blow at it hard, always in one direction. Eventually the outer edge will break up and blow away, leaving a sharp edge, that will also retreat with time as the wind continues to blow.

Here the winds are eroding that cliff, causing periodic avalanches which dissolve into sand that then blows away, leaving no debris pile at the base of the cliff. The ridges indicate harder material, that breaks away last, which is why there are some ridgelines extending outward from the scarp in line with these ridges. At the same time, these ridges of harder ash still break up with time, as some are cut off suddenly at the cliff edge.

Air leak in Russia’s half of ISS continues and has increased slightly

9:34 am

The leak in the Russia half of ISS continues to bleed air from the space station and has even increased slightly in recent months, though both NASA and Roscosmos say the rate of loss is tiny and poses no danger to the station’s inhabitants.

“There is no threat to the crew or the station itself,” [Roscosmos] said in a statement carried by Russian news agencies. Roscosmos’ statement followed comments by Joel Montalbano, NASA’s station project manager, who noted Wednesday that the leak in the Russian segment has increased but emphasized that it remains small and poses no threat to the crew’s safety or vehicle operations.

As indicated by the graphic to the right, the air loss is suspected to come from stress fractures in the Zvezda module, the station’s second oldest and one in which many dockings have occurred over the past two decades. Russia had suspended dockings in this port shortly after the leaks and cracks were detected, but have apparently resumed those dockings recently. One wonders if this new activity is contributing to the increase in loss of air.

Final images from Odysseus, lying on its side

9:23 am

One of three pictures downloaded after landing
Click for original picture.

In a press conference yesterday, NASA and the private company Intuitive Machines released three pictures taken by the Odysseus lunar lander after it came down a bit too fast, skidded on the ground so that one leg broke, and then tilted over.

The first images from the lunar surface are now available and showcase the orientation of the lander along with a view of the South Pole region on the Moon. Intuitive Machines believes the two actions captured in one of their images enabled Odysseus to gently lean into the lunar surface, preserving the ability to return scientific data.

The best picture, reduced and annotated to post here, is to the right. The spacecraft is tilted about 30 degrees from the vertical. Another picture showed the broken leg on the lander’s other side. The “two actions” mentioned in the NASA quote above refer to the issues that caused the broken leg: the limited ground data the lander used to land, and its larger than expected lateral speed.

The spacecraft is expected to be shut down by today because of lack of power and the advent of the long lunar night. Company officials remain hopeful it will come back to life when the sun rises in several weeks.

Officials from both NASA and Intuitive Machines have correctly noted that this was an engineering test mission, so even these failures make it a success in that the company can use them to improve the next lander. Nonetheless, it would have been nice if things had worked better on this first flight, especially because the problem that led to all the breakdowns, the failure to turn the lander’s range finding system back on after installation on the rocket, was an incredibly stupid human error that should not have happened at all.
