Rocket Lab launches classified smallsat for National Reconnaissance Office

12:36 am

Rocket Lab in the early morning hours of March 21, 2024 successfully launched a classified payload for the National Reconnaissance Office, its Electron rocket lifting off from Wallops Island in Virgina.

For this launch Rocket Lab made no attempt to recover its first stage. As of posting the payloads had not yet been deployed.

A Chinese Long March 2D launch was also scheduled to occur just prior to the Rocket Lab launch, but as of posting there was no word on whether that launch had taken place.

The leaders in the 2024 space race:

27 SpaceX
11 China
4 Rocket Lab
3 Russia

American private enterprise presently leads the rest of the world combined in successful launches 32 to 20, while SpaceX leads the entire world, including American companies, 27 to 25.

Cracking terraces in Valles Marineris

3:27 pm

Overview map

Cracking terraces in Valles Marineris
Click for original image.

Inset

Today’s cool image returns us to the truly spectacular terrain found on the floor of West Candor Chasma, one of the giant side canyons that form Valles Marineris, the biggest canyon in the solar system, many times larger than the Grand Canyon on Earth.

The picture to the right, cropped, reduced, and sharpened to post here, was taken on January 5, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). On the overview map above its location is indicated by the red dot in the inset. The two green dots mark previous cool images from August 2022 and February 2024.

All three images show the same wild alternating dark and light terracing, suggesting many sedimentary layers like those seen in our Grand Canyon, but enhanced by the different erosion processes of the thin Martian atmosphere and its one-third Earth gravity.

The second image to the right zooms in on the area indicated by the rectangle. What makes this area doubly interesting are the cracks that appear to cut through the terraces. In the north-south crack it also appears that the terraces are now offset on each side of the crack.

Apparently, some event, likely an earthquake that occurred after the terraces formed, caused the ground to rip apart, with the earth shifting sideways on either side. Though the seismometer on the InSight lander detected no major quakes in this region, this image suggests they have occurred here, sometime in the past.

To give you a sense of scale, the canyon’s nearby rim to the west is about 14,000 higher, making that canyon wall two to three times taller than the walls of the Grand Canyon.

Is the Republican Party finally doing the election due diligence it should have been doing since 2020?

1:31 pm

The Republican Party: Finally waking up?
The Republican Party: Is it finally waking up?

Too late is better than nothing: Three stories in the past week suggest that after almost four years of twiddling its thumbs, the Republican National Committee (RNC) is finally beginning to do the hard work necessary to prevent Democratic Party vote tampering in the 2024 election.

This new apparently aggressive approach began almost immediately after Michael Whatley and Lara Trump took over as co-chairs of the committee from Ronna McDaniel, who for seven years seemed incapable of achieving anything beneficial for Republicans, or conservatives for that matter. In addition, a new chief of operations, Chris LaCivita, was brought in.

Four days after these people took over they did a complete house-cleaning of the staff at the committee.

As we reported Monday night, political director Elliott Echols and one of his top staffers, Tripp Looser; communications director Keith Schippert; Mike Mears (chief of staff to former co-chair Drew McKissick); and the lead data director were all given their walking papers. We also reported at that time that an email went out to staff from Sean Cairncross, LaCivita’s number two, stating that all existing vendor contracts were going to be reviewed.

We now know that every one of the RNC’s regional political directors, state directors, RNC Community Center staffers, and members of its election-integrity team were fired. Some of those let go were informed that they could reapply for their old positions, and the rest were simply let go but paid until the end of March.

This article also outlines the major restructuring of the entire committee management staff and programs. Included in these changes was the hiring of two people to coordinate the committee’s election integrity legal effort.

LaCivita brought in Charlie Spies, one of the most experienced Republican election law attorneys out there, as chief counsel, and former Trump attorney Christina Bobb as senior counsel for election integrity.

The arrival of Spies and Bobb has apparently resulted in immediate action, in two states, with more predicted. Two days after these changes the committee sued Michigan Secretary of State Jocelyn Benson for failing to maintain proper voter rolls, as required by law. One week later the committee followed up with a similar lawsuit against Nevada’s secretary of state Cisco Aguliar. As noted in the introduction to the Michigan lawsuit (available here [pdf]):

Spanish high-altitude balloon company to fly fullsize prototype capsule from Saudi Arabia

10:20 am

The Spanish high-altitude balloon startup Halo is now planning to fly from Saudi Arabia the second test flight of its fullsize prototype tourist capsule.

Headquartered in Madrid, the company, which specialises in stratospheric commercial flights, will embark on its sixth test flight from the kingdom in June, the company said in a release, with conditional approval from the Communications, Space and Technology Commission (CST), the Saudi Arabia authority responsible for space regulation.

Halo Space CEO Carlos Mira said in a statement that this test will validate the integrated operation of all critical systems, “bringing us one step closer to our goal,” which includes plans to begin commercial flights in 2026.

The company plans to set up bases for flights in Saudi Arabia, the U.S., Australia, and Spain, where it hopes to do high altitude tourist balloon flights to about 20 miles elevation. We should also not be surprised if it does classified reconnaissance flights for Saudi Arabia as well.

Whether it will do what it says however still depends on the final outcome of a lawsuit against it by another Spanish company, Zero 2 Infinity, which claims Halo stole its technology. The courts have ruled in Zero 2’s favor, but whether a final settlement has occurred is unclear.

SpaceX’s next Superheavy/Starship launch, according to SpaceX

10:06 am

According to SpaceX’s CEO, Gwynne Shotwell, the company hopes to be ready to fly its fourth orbital test flight of Superheavy/Starship in about six weeks, and will not attempt to deploy any Starlink satellites, as I speculated earlier this week.

“We’ll figure out what happened on both stages,” she said, not discussing what may have gone wrong with either, “and get back to flight hopefully in about six weeks,” or early May. She added that the company doesn’t expect to deploy Starlink satellites on the next Starship launch, as some had speculated. “Things are still in trade, but I think we’re really going to focus on getting reentry right and making sure we can land these things where we want to land them.”

The story however provided one very important tidbit of information about the launch license process from the FAA. Kelvin Coleman, FAA associate administrator for commercial space transportation, noted that after the second test flight in November 2023 “the company completed that report in several weeks.”

That statement confirms my conclusion in late December that SpaceX had been ready to launch in early January, but couldn’t do it because the FAA had to spend another two months rewriting SpaceX’s investigation report.

We should therefore not be surprised if the same thing happens on the next test flight. Shotwell says SpaceX hopes to be ready to launch in early May. That means it will likely submit its report to the FAA around then. Expect the agency to then spend at least one to two months retyping the report, as it has done now after both the first and second flights.

Based on this information, we should now expect the fourth flight to occur sometime in the June-July timeframe, with July more likely.

I am sure that the people at the FAA want to move as quickly as possible. I am also sure their bosses in the White House are demanding they dot every “i” and cross every “t”, with meticulous care, so that things cannot move as fast as desired. That has been the pattern since Joe Biden took office, and I have seen no evidence of that changing now.

A relatively dim star is expected to become one of the brightest in the sky later this year

9:49 am

As it has done twice before at intervals of 80 years, a relatively dim star is expected to go nova later this year, becoming for a short time one of the brightest stars in the sky.

Located in the Northern Crown constellation, T Coronae Borealis (T CrB) is a pretty average looking star, most of the time. With a brightness of about magnitude +10, it’s right on the limits of what you could see with a pair of binoculars, and even if you do go looking there’s not much to see.

At least, that’s the case for about 79 out of 80 years. But on that 80th year, the star suddenly brightens drastically up to around magnitude +2, which puts it on par with the north star Polaris. That makes it one of the brightest stars in the night sky, easily visible with the naked eye even when washed out by city lights. This once-in-a-lifetime outburst last occurred in 1946, and before that 1866.

And lucky for stargazers, T CrB seems to be about two years ahead of schedule, with astronomers predicting it will flare up again between March and September 2024. It’ll appear as a bright ‘new’ star for a few days with the naked eye, and a little over a week with binoculars, before it settles down again for another few decades. Astronomers noticed last year that T CrB had started to dim, which data from 1945 showed preceded the last brightening event.

The star is actually a binary, made up of a white dwarf and a red giant. The white dwarf is pulling material from the red giant, and as that new material piles up, it eventually gathers enough mass to go critical and produce a thermonuclear explosion. The result is a nova, a smaller version of a supernova that unlike supernovae occurs repeatedly.

Orbit Fab announces price tag for installing its refuelling port on satellites

9:40 am

Orbit Fab has now set a price of $30,000 for its satellite refuelling port, should companies decide to install one on their satellites.

Orbit Fab on March 19 … unveiled pricing for the RAFTI refueling ports, setting the price tag at $30,000 per unit. Executives said the number was based on market research into the pricing of fill and drain valves widely used across the satellite industry. “With a qualified port design, satellite manufacturers can now incorporate RAFTI with more confidence, knowing it has passed rigorous testing,” said Adam Harris,Orbit Fab’s chief commercial officer.

Clearing these tests paves the way for Orbit Fab to deliver the first 100 RAFTI units to U.S. government and commercial customers over the next year, Harris said.

Once in orbit, an Orbit Fab refueling tanker will rendezvous with the satellite, dock at the port, and pump new fuel into the satellite.

While no actual refueling missions are presently scheduled, the company is negotiating with both the Air Force and Space Force to fly such a mission to satellites they have already outfitted with this port.

Indian rocket startup to attempt suborbital test launch this week

9:30 am

India’s spaceports

Agnikul, one of the two rocket startups in India attempting to enter the launch market, is targeting March 22, 2024 for the first suborbital test launch of its Agnibaan rocket, lifting off from its own private launch site off the eastern coast of India.

Agnikul Cosmos is all set to conduct the maiden launch of the Agnibaan launch vehicle on Friday. The maiden test is aimed at validating the working of the first stage of the rocket that will power the vehicle in future missions.

Dubbed Agnibaan SOrTeD, the Sub Orbital Technology Demonstrator mission will see the maiden launch from India’s first private launchpad which has been developed with assistance from the Indian Space Research Organisation (ISRO).

The map shows the location of Agnikul’s launch site, south of ISRO’s long established spaceport at Sriharikota. The third spaceport at India’s southern tip is a new facility being built by ISRO.

If this launch is successful, Agnikul will have caught up with the other Indian rocket startup Skyroot, which conducted its own suborbital test launch in November 2022.

ESA: Euclid vision cleared after being fogged by ground ice, after launch

9:13 am

The European Space Agency (ESA) today announced that engineers have successfully “de-iced” the optics of its new Euclid space telescope that developed after it was launched in July 2023.

It was always expected that water could gradually build up and contaminate Euclid’s vision, as it is very difficult to build and launch a spacecraft from Earth without some of the water in our planet’s atmosphere creeping into it. For this reason, there was an ‘outgassing campaign’ shortly after launch where the telescope was warmed up by onboard heaters and also partially exposed to the Sun, sublimating most of the water molecules present at launch on or very near Euclid’s surfaces. A considerable fraction, however, has survived, by being absorbed in the multi-layer insulation, and is now being slowly released in the vacuum of space.

After a huge amount of research – including lab studies into how minuscule layers of ice on mirror surfaces scatter and reflect light – and months of calibrations in space, the team determined that several layers of water molecules are likely frozen onto mirrors in Euclid’s optics. Likely just a few to few tens of nanometres thick – equivalent to the width of a strand of DNA – it’s a remarkable testament to the mission’s sensitivity that it is detecting such tiny amounts of ice.

While Euclid’s observations and science continue, teams have come up with a plan to understand where the ice is in the optical system and mitigate its impact now and in the future, if it continues to accumulate.

It appears this new process has worked, according to a short update at the link.

Normally spacecraft are vented both on the ground during thermal testing, as well as when they reach orbit. It appears some of these normal procedures were either insufficient for Euclid’s needs, or threatened its optics if done as usual. This press release suggests that Euclid required very targeted venting processes that would not harm its sensitive optics, and that the procedures have worked.

I must admit I am suspicious of these claims. During development and after launch Euclid has had a number of problems. First, back in 2017 the NASA instrument on the telescope had to be completely rebuilt when it was found to be defective. Second, after launch engineers discovered unexpected light leaks on the mirror that now limit where it can look. Third, the telescope required a software patch to fix its pointing system, which was confusing cosmic rays for guide stars, causing it to shift positions randomly.

I can’t help wondering if this icing on the mirrors was also due, not to actual planning as suggested by ESA’s press release, but to poor ground testing and engineering that missed what is a common problem on spacecraft and thus required a post-launch improvised fix. I admit I might be wrong, but I still wonder.
