John Williams – Imperial March

6:01 pm

An evening pause: What is most important about this performance is that Williams was doing the conducting on his 90th birthday. The only sour note of this performance is the idiotic masks they made some members of the orchestra wear. Obviously, a horn player can’t give anyone an infection, but a violin player can. Note too how all the VIPs on the front of the stage (such as Steven Spielberg) were also immune from COVID and didn’t need masks either. What fools and hypocrites.

Hat tip Phil Berardelli.

A Martian crater with a wake of lava

12:47 pm

Overview map

Cool image time! Today’s cool image begins with the overview map to the right. The white dot marks its location, on the western edge of Amazonis Planitia and about 1,000 miles east of the giant shield volcano Elysium Mons.

This is a region of numerous flood lava events that appear to cover the knobby mountainous terrain that was once here. We know that past terrain was knobby because in the black outline just south of this picture the knobs are everywhere, short peaks sticking up from a very flat flood lava plain. The region is also on the northern edge of the dry equatorial regions of Mars, at 27 degrees north latitude. It is likely there is little near surface ice here.

These details will help explain the cool image itself.

Pushback: Judge blocks race-based program of Biden administration

11:45 am

Modern segregation
Modern Democratic Party segregation

“Segregation today, segregation tomorrow, segregation forever!” On June 5, 2023 federal Judge Mark Pittman of the Northern District of Texas ruled [pdf] that a race-based development agency, dubbed the Minority Business Development Agency (MBDA) and created under Biden administration, was patently illegal under both the U.S. Constitution and numerous civil rights laws, and must cease awarding grants based on race.

The ruling was in response to a lawsuit [pdf] filed for three individuals by the Wisconsin Institute for Law & Liberty (WILL), one of whom, Christian Bruckner, was specifically told by the local office of MBDA “…that it could not help him because of his race.” The lawsuit notes that:

NASA official in charge of its manned program denigrates the idea of fixed-price contracts

9:32 am

Jim Free, apparently hostile to commercial space despite running the NASA manned program dependent on it
Jim Free, apparently hostile to commercial space despite
running the NASA manned program dependent on it

Eric Berger on June 16, 2023 wrote up a careful analysis of comments made by NASA official Jim Free, who is in charge of its Artemis manned program, when he appeared on June 7, 2023 before the Aeronautics and Space Engineering Board and Space Studies Board in Washington, DC.

During that appearance, in which Free provided an update on the program’s status, including admitting that the manned lunar landing will not happen in 2025 but in 2026 — something that everyone in the space industry has known for years but NASA had been denying — Berger then noted this further comment by Free:

Oddly, Free also questioned the value of the contract mechanism that NASA used to hire SpaceX and its Starship lander. “The fact is, if they’re not flying on the time they’ve said, it does us no good to have a firm, fixed-price contract other than we’re not paying more,” he said.

Free did this after trying to place the entire blame for the launch delay on SpaceX, made worse by the regulatory delays being imposed on it by the FAA.

Berger than proceeded to outline in great detail why fixed-price contracts work far better than cost-plus contracts — also known widely in the space industry and detailed myself in Capitalism in Space. To sum up, cost-plus contracts produce very little but cost gobs of money, while fixed-price contracts save money while guaranteeing results. He then asked, “What’s going on here?” and answered it as follows:

SpaceX successfully launches Indonesian broadband satellite

8:48 am

SpaceX yesterday successfully launched an Indonesian broadband satellite, using its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its twelfth flight, landing on a drone ship in the Atlantic. The fairing halves completed their seventh and ninth flights respectively.

The leaders in the 2023 launch race:

41 SpaceX
23 China
8 Russia
5 Rocket Lab

American private enterprise now leads China 46 to 23 in the national rankings, and the entire world combined 46 to 39, with SpaceX by itself still leading the rest of the world, excluding other American companies, 41 to 39.

Rocket Lab completes first suborbital test launch of its Electron rocket

8:42 am

As part of its contract for providing the Defense Department with a testbed for hypersonic testing, Rocket Lab on June 17, 2023 successfully completed the first suborbital test launch of its Electron rocket.

The HASTE suborbital launch vehicle is derived from the Company’s Electron rocket but has a modified Kick Stage for hypersonic payload deployment, a larger payload capacity of up to 700 kg / 1,540 lbs, and options for tailored fairings to accommodate larger payloads, including air-breathing, ballistic re-entry, boost-glide, and space-based applications payloads. By leveraging the heritage of Rocket Lab’s low-cost Electron – the world’s most frequently launched commercial small launch vehicle – HASTE offers true commercial testing capability at a fraction of the cost of current full-scale tests.

Because of its military nature, Rocket Lab’s press release was generally terse in providing details. Sources in the industry tell me that this launch was designed to prove out the required suborbital capabilities of Electron prior to the first hypersonic test flight. When that flight takes place, it will carry a hypersonic test vehicle built by another company, Hypersonix.

Rocket Lab with this launch demonstrated again the smart flexibility of the company. It only announced this suborbital concept for Electron in April. Only two months later it has test flown it. It is now ready to fly an actual hypersonic test flight, and waits only for the test vehicle to be provided by Hypersonix. The speed of this program leap-frogged Stratolaunch, which is also offering its Roc airplane and Talon hypersonic test vehicle to the military but started its project in late 2020 and is still not ready for flight.

PLD’s first suborbital test launch aborted just prior to launch

1:07 pm

According to company officials, the first suborbital test launch of PLD Miura-1 rocket was aborted today just prior to launch because some of the umbilical fuel and power lines failed to disconnect as planned.

The launch was from PLD’s launch site in Spain. No word when the company will try again. Before it can build its orbital Miura-5 rocket it needs the test data from this suborbital launch.

The icy mesas of Mars’ glacier country

Overview map

The ice mesas of Mars' glacier country
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on March 25, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labeled this image “Cross-Section of Glacier-Like Form,” probably because the mesa in the center of the picture clearly shows numerous layers as you descend from its peak to the surrounding plains, an elevation difference of about 200 feet.

The white dot about 250 miles due south of Lyot Crater on the overview map above marks the location of this mesa, inside the chaos terrain of Deuteronilus Mensae that is the western section of the 2,000 long strip in the northern mid-latitudes of Mars that I call glacier country, since practically every image, like today’s, suggests the presence of glaciers.

The oblique mosaic below, created using MRO’s context camera images, illustrates this fact even more spectacularly.

Lightning on Jupiter

Lightning on Jupiter
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on December 30, 2020 by Juno during its 31st close fly-by of Jupiter, and was enhanced and processed by citizen-scientist Kevin Gill.

In this view of a vortex near Jupiter’s north pole, NASA’s Juno mission observed the glow from a bolt of lightning. On Earth, lightning bolts originate from water clouds, and happen most frequently near the equator, while on Jupiter lightning likely also occurs in clouds containing an ammonia-water solution, and can be seen most often near the poles.

Juno was about 20,000 miles above Jupiter’s clouds when it took this picture, located at about 78 degrees north latitude.
