First Juno images of Io from December 30th fly-by

Io as seen by Juno on December 30, 2023
For original global image go here. For original of inset go here.

The first raw Juno images taken of the Jupiter moon Io during its close fly-by on December 30, 2023, the closest in more than twenty years, have been released by the science team and citizen scientists have begun processing them.

The global picture to the right, rotated and reduced to post here, was processed by Kevin Gill. The inset of the volcanic mountains near the terminator was processed by Thomas Thomopoulos. As he notes, to obtain better detail he enhanced the colors and image and then zoomed in.

In the inset, note the northeast flows coming off the two mountains near the center. With the lower mountain, this flow appears to lie on top of a larger flow that extended out almost to the mountain to the right.

Io is a planet of continuous volcanic activity. For example, when the global image above was taken, the plume of a volcano eruption was visible on the right horizon, as shown in this version, its exposure adjusted by Ted Stryk. Catching such eruptions on Io is not unusual, considering its continuous volcanic activity generated by the tidal forces the planet undergoes from its orbit around Jupiter. In fact, the very first plume was imaged in 1979 by Voyager 1 during its short fly-by, and proved a hypothesis of such activity that scientists had only published one week earlier.

India completes first launch of 2024

India’s space agency ISRO early today completed the first launch of 2024, its PSLV rocket placing an X-ray telescope into orbit along with ten payloads on its fourth stage, which is functioning as an orbital tug. Most appear [pdf] to be experiments that will remain on board, but one is an amateur radio smallsat that might be released.

As this is the only launch so far in 2024, India leads the race. It will certainly not remain the leader.

My annual global launch report for 2023 will be published tomorrow, after the holiday.

China launches “test satellite for satellite internet technologies”

China today launched what it described as “a test satellite for satellite internet technologies,” its Long March 2C rocket lifting off from its Jiuquan spaceport in the northwest of China.

No word on where the lower stages crashed, both of which use very toxic hypergolic fuels. Nor was there any additional information about the satellite, though the description suggests this is a prototype satellite for a Starlink-type constellation, several of which China’s government has proposed building.

The leaders in the 2023 launch race:

96 SpaceX
66 China
19 Russia
8 Rocket Lab
7 India

American private enterprise still leads China in successful launches 110 to 66, and the entire world combined 110 to 103. SpaceX in turn trails the rest of the world (excluding other American companies) 96 to 103.

SpaceX successfully completes static fire tests of both Superheavy and Starship

SpaceX today successfully completed static fire tests on both Superheavy and Starship prototypes intended to fly on its next orbital test flight.

The video at the link is four hours long. The Starship engine burn occurs at 1 hour 15 minutes and lasts about five seconds. The Superheavy burn takes place at 2 hours 42 minutes, and lasts about ten seconds. Both burns appeared to operate exactly as planned, though obviously an inspection of the launchpad under Superheavy will have to take place to see if its deluge system operated as intended.

Once again, SpaceX is demonstrating that it will be ready to go for the third orbital test launch of this rocket in mere weeks. Based on these tests today as well as past operations, it seems that all the company needs to do now is stack Starship on top of Superheavy, do another dress rehearsal countdown, and then go.

It won’t however. There is no word from the FAA on when it will issue a launch permit. Based on the previous launch, it will likely not issue the permit when SpaceX says it has completed its investigation of the last launch and is ready to fly again. Instead it will take another month or two writing up its own report (which will essentially reword what SpaceX has told it). Then, once the FAA is finished only then will the Fish and Wildlife Service begin to write up its report (as happened in the fall), causing further delays.

I repeat my prediction from November: No launch until March, at the earliest. The federal government continues to stand in the way of progress, and freedom.

Republicans propose another deep state bureaucracy to enforce civil rights laws

Failure Theater!

Failure theater: In their typically impotent attempt to fight the leftist movement that is imposing a new racial bigotry across America, several Republicans in Congress have proposed a new special government office in Washington that will be specifically assigned the job of preventing racial discrimination at universities.

The College Admissions Accountability Act, introduced by Sen. J.D. Vance (R., Ohio) and Rep. Jim Banks (R., Ind.), would establish a special inspector general within the Education Department—separate from the Office of Civil Rights—to probe potential violations of the colorblind standard set forth in Students for Fair Admissions v. Harvard, which ruled that race-conscious admissions programs violate the 14th Amendment. The bill would also bar schools that flout the decision from receiving any form of federal aid.

…The bill, which appropriates $25 million for the new role and is cosponsored by Sens. Ted Budd (R., N.C.), Mike Braun (R, Ind.), Josh Hawley (R., Mo.), Eric Schmitt (R., Mo.), and Marco Rubio (R., Fla.), does include a sunset clause that would terminate the office after 12 years. Republicans seem to be betting that recalcitrant universities will, after a decade of robust enforcement, throw in the towel and evolve colorblind norms.

These senators and congressmen, along with several conservative think tanks, think naively that this office will the place for anyone of any race to go to get justice should a university receiving federal funds create a program that specifically excludes them solely because of their race. The aim will supposedly be to target specifically the new Diversity-Inclusion-Equity programs at universities and in governments that are imposing this new discrimination against whites, Asians, and Jews.

The foolishness of this plan is hard to measure. » Read more

The ancientness of rocks on Mars

Ancient rocks on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on December 27, 2023 by the high resolution camera on the Mars rover Curiosity. It shows what is a somewhat typical rock found on the ground as Curiosity climbs Mount Sharp in Gale Crater.

Two features stand out. First, the many layers illustrate again the cyclical nature of Martian geology. Many sedimentary events occurred over a long time to create this rock, each cycle putting down a new layer, with some intervening time periods possibly removing layers as well. Such layering has now become evident in both ground photos taken by rovers as well as orbital images.

Second, the delicate nature of some layers indicates the incredibly slow erosion process on Mars, enhanced by the red planet’s one-third gravity. The atmosphere is incredibly thin, less than 0.1% of Earth’s. Yet given time the wind had been able to wear away the edges of this rock. The thin atmosphere and light gravity has also allowed some material to remain in a delicate manner that would be impossible on Earth.

Thus, for these thin flakes to have formed has required a great deal of time. The very nature of this rock speaks of an ancient terrain, shaped slowly by inanimate processes with no active life around to disturb things.

Curiosity science team releases movies of Mars from dawn to dusk

Using its front and rear hazard avoidence cameras, the Curiosity science team had the rover take two full sets of images looking in one direction for twelve hours straight in order to create two movies of Mars that show an entire day, from dawn to dusk.

I have embedded both movies below. From the press release:

When NASA’s Curiosity Mars rover isn’t on the move, it works pretty well as a sundial, as seen in two black-and-white videos recorded on Nov. 8, the 4,002nd Martian day, or sol, of the mission. The rover captured its own shadow shifting across the surface of Mars using its black-and-white Hazard-Avoidance Cameras, or Hazcams.

Instructions to record the videos were part of the last set of commands beamed up to Curiosity just before the start of Mars solar conjunction, a period when the Sun is between Earth and Mars. Because plasma from the Sun can interfere with radio communications, missions hold off on sending commands to Mars spacecraft for several weeks during this time.

The first looks forward, into Gediz Vallis, where Curiosity will eventually travel. The second looks back down Mt Sharp and out across the rim of Gale Crater.

Kazakhstan approves Russia use of Baikonur through 2024

Though Russia supposedly has a long term lease for launching rockets from its Baikonur spaceport in Kazakhstan, Kazakhstan this week revealed that it has just now approved the Russian plan of launches there for 2024.

The Government of Kazakhstan approves the plan of spacecraft launches for 2024 presented by the Russian side within the framework of the state program of the Russian Federation “Space Activities of Russia”, programs of international cooperation and commercial projects from Baikonur Cosmodrome.

Kazakhstan has increasingly become a bit hard-nosed about Russia’s long term lease. For example, in March seized control of the launchpad Russia hoped to use on its new Soyuz-5 rocket, leaving that rocket with no place to launch. And for the last decade there have been hints from both countries that the deal is souring, with Russia suggesting it will shift launch operations entirely to its new spaceport in Vostochny and Kazakhstan politicians eager to see Russia go.

China completes work on first dedicated “commercial” launchpad

China announced today that it has completed work on first launchpad at its Wenchang spaceport on the island of Hainan off the southern coast of China that it intends to dedicate to launches by its many pseudo-private companies.

Construction of the No. 1 launch pad started in July 2022, and the equipment-installation phase is almost complete. The No. 2 launch pad is still at the construction phase, with the capping of the diversion trough’s main body now finished. On-site equipment installation is due to be completed by the end of May 2024.

The article also notes that this pad is a dedicated site for launching China’s new Long March 8 rocket, which means it isn’t really dedicated to commercial launches at all. These pseudo-companies might use it, but they will do so under orders from the communist Chinese government, which supervises everything they do.

Russia and NASA agree to extend ISS astronaut exchanges on each other’s spacecraft through 2025

Russia and NASA have agreed to extend their barter deal through 2025, whereby each nation sends astronauts to ISS periodically on the other nation’s rockets and capsules.

This is a barter deal, with no exchange of money. The fundamental idea is to make sure astronauts on board ISS understand how the capsules from each nation operate in case of emergency. Russia had initially resisted signing such a deal after SpaceX began providing NASA its Dragon capsules and Falcon 9 rocket to get astronauts to ISS. It said this was because it did not trust SpaceX’s technology, but I suspect Roscosmos was also hoping to squeeze some cash from NASA as it was no longer being paid to fly U.S. astronauts on its Soyuz rocket and capsule. That attempt was futile. For numerous political reasons there was no way NASA was going to pay Russia anything in this barter deal.

Russia then signed on, and will keep extending this agreement until the day ISS is retired, or it finally launches its own station (something that is becoming increasingly unlikely).
