China launches remote sensing satellite using rocket from pseudo-company

9:00 am

The Chinese pseudo-company Galactic Energy completed another successful orbital launch today, using its Ceres-1 rocket solid-fueled rocket carrying a remote sensing satellite and lifting off from the Jiuquan spaceport in the northwest interior of China.

As with the pseudo-company’s previous launch, the state-run press made no mention of the company in its reporting, underlining the fact that it really is simply another government-controlled entity that simply adds private investment and the profit-motive to its operations.

No word on where the rocket’s lower stages crashed within China.

The leaders in the 2023 launch race:

57 SpaceX
37 China
12 Russia
7 Rocket Lab

In the national rankings, American private enterprise still leads China in successful launches 66 to 37. It also leads the entire world combined, 66 to 60, while SpaceX by itself now trails the rest of the world (excluding American companies) 57 to 60 in successful launches.

  • Perseverance science team touts rover’s 19th core sample

    • If you listen closely to the two scientists in the video, they really can only guess about much of this geology, since Perseverance does not have the same geological capabilites as Curiosity. They can make some superficial analysis of the rocks, but the more detailed work will have to wait until those core samples are returned to Earth. Curiosity however can not only drill, but it has equipment to analyze those drill samples itself, there. While Curiosity can’t do what an Earth lab would do, it does it now. With Perseverance we will have to wait a decade or more to get to the samples.

Big mountains everywhere inside Valles Marineris

11:45 am

Big mountains in Valles Marineris
Click for original image.

While the giant canyon Valles Marineris on Mars is known best as the biggest known canyon in the solar system — large enough to cover the continental United States several times over — that size tends to diminish the mountainous nature of its interior. Today’s cool image attempts once again (see for example these earlier posts here, here, here, here, and here) to illustrate that stupendous and mountainous nature.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 15, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The goal of the picture was to get a better view of the numerous layers of this terraced cliff wall. What I see, however from my tourist’s perspective, is a steep wall that descends almost 4,500 feet from the high to the low point in just over three miles. This is as steep if not steeper than the walls of the Grand Canyon.

Biden’s Justice Department sues SpaceX

9:51 am

The corrupt and very partisan Justice Department of the Biden administration today sued SpaceX for discriminating against refugees and illegal immigrants because it restricts hiring to “U.S. citizens and lawful permanent residents.”

The lawsuit states SpaceX “failed to fairly consider” and “refused to hire” the asylees and refugees who ended up applying anyway. It also alleges that SpaceX “wrongly claimed” that the US’s export control laws allowed it to only hire US citizens and lawful residents. Additionally, the DOJ claims SpaceX hired “only” US citizens and green card holders from September 2018 to September 2020.

“Our investigation found that SpaceX failed to fairly consider or hire asylees and refugees because of their citizenship status and imposed what amounted to a ban on their hire regardless of their qualification, in violation of federal law,” Kristen Clarke, the assistant attorney general of the DOJ’s Civil Rights Division, says in a statement.

Justice is demanding compensation and back pay for anyone “deterred or denied employment”, as well as civil penalties.

This suit is utter garbage and puts SpaceX between a rock and a hard place. I guarantee if SpaceX had hired any illegal or refugee who was not yet a legal citizen, Biden’s State Department would have immediately sued it for violating other laws relating to ITAR (the export control laws mentioned) which try to prevent the theft of technology by foreign powers.

The Biden administration considers Elon Musk an opponent, and since it is now moving to indict and even imprison all political opposition, it is no surprise it is beginning to use lawfare against him. As I have written repeatedly, it has almost certainly pressured the FAA to slow walk any launch license approvals for SpaceX’s Starship/Superheavy. This lawsuit today simply provides further evidence that my prediction will be right that the next orbital test flight of that rocket will be delayed months.

North Korea fails again to get a military reconnaissance satellite into orbit

9:33 am

According to a report in North Korea’s state run press, a launch attempt of its new rocket Chollima-1 rocket failed to reach orbit at dawn today, its payload of a classified military reconnaissance satellite falling into the ocean.

The Korean Central News Agency (KCNA) in Pyongyang reported that the National Aerospace Development Administration launched the new Chollima-1 rocket “at dawn” August 24 from the Sohae Satellite Launch Center. The first and second stages worked as planned, but “the launch failed due to an error in the emergency blasting system during the third stage flight” according to KCNA.

South Korea’s Yonhap news agency identified the satellite as Malligyong-1, a military reconnaissance satellite and reported the launch time as 3:50 am local time (2:50 pm August 23 EDT).

The flight path can be found here. An earlier attempt in May failed also, but the cause was not specified. South Korea did recover the first stage and satellite from the May failure, claiming later the satellite had “no military utility.”

I expect South Korea to once again attempt recovery operations, but because the rocket traveled farther I also expect the chances of any recovery of material to be more unlikely.

India’s Pragyan rover has successfully been deployed on the lunar surface

9:23 am


Click for interactive map.

According to a tweet from India’s space agency ISRO late yesterday, the Pragyan rover has successfully rolled down its ramp and is now deployed on the lunar surface.

No further updates have yet been released. According to ISRO’s mission webpage the instruments on both Vikram and Pragyan are as follows:

Lander payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature; Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site; Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies.

Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site.

Pragyan’s two spectroscopes are likely similar to instruments on Curiosity and Perseverance on Mars, and allows some good surface analysis. Without a scoop however there will be no analysis of anything below the ground, unless the rover can upend a rock using its wheels.

Rocket Lab launches a satellite reusing one rocket engine from previous flight

9:20 pm

Rocket Lab not only successfully launched a satellite tonight (August 24 in New Zealand), its first stage used a rocket engine that had flown previously.

In addition, the first stage was designed to be reused, and was quickly recovered after it splashed down in the Pacific. The plan is to refly either this or another recovered first stage in one of the company’s upcoming launches in the coming months, making Rocket Lab the second private company in the world, after SpaceX, to reuse a first stage.

The leaders in the 2023 launch race:

57 SpaceX
36 China
12 Russia
7 Rocket Lab

In the national rankings, American private enterprise now leads China in successful launches 66 to 36. It also leads the entire world combined, 66 to 59. SpaceX by itself still trails the rest of the world (excluding American companies) 57 to 59 in successful launches.

Where the Martian landscape begins to dry out

Where Mars begins to dry out
Click for original image.

Today’s cool image to the right, cropped, reduced, and sharpened to post here, provides us a glimpse at the lower mid-latitudes of Mars where the terrain is beginning to dry out as we move south. The picture was taken on April 29, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists label “large linear features.”

The main north-south ridge is only about 20-25 feet high, and its meandering nature (which can be seen more clearly in the full image) suggests it is possibly an inverted channel, formed when the bed of a former canyon gets compressed by the water or ice that flows through it, and when the surrounding terrain gets eroded away that channel bed becomes a ridge.

These ridges however could also possibly be volcanic dikes, where magma had pushed up through fractures and faults to form these more resistant ridges.

First mission in Isaacman’s private space program delayed again

9:56 am

The first mission in the Polaris space program of manned flights by billionaire Jared Isaacman, using SpaceX’s manned spacecraft and rockets, has now been delayed until early in 2024.

Isaacman, in the podcast interview, suggested the delays were linked to the development of a new spacesuit required for a spacewalk, the first by a private astronaut mission, planned for Polaris Dawn. “We’ve had a little bit more free time this summer than we probably would have expected,” he said, which he attributed to the timing of spacesuit development and training. That effort “doesn’t always sync up, so we’ve had a little more free time with family and work this summer.”

That new suit, billed as the first new spacesuit developed in the United States in four decades, is critical to future human activities on moon and Mars, he argued. “We’re going to need spacesuits that don’t cost hundreds of millions of dollars in order to do that. We’re pretty excited because the suit that we are testing out, the evolution of it someday could be very well worn by people that are walking on the moon or Mars.”

This mission, dubbed Polaris Dawn, will use a Falcon 9 and one of SpaceX’s fleet of four manned Dragon capsules to spend several days in Earth orbit while conducting that first private spacewalk. Isaacman’s entire Polaris program includes two more manned missions,the second possibly aimed at raising and even doing maintenance on the Hubble Space Telescope, and the third using Starship to go around the Moon.

Isaacman has already flown one private mission in space, in 2021, dubbed Inspiration4. It flew for three days in orbit, carrying four passengers, including Isaacman himself. Since it did not dock with ISS, it was an entirely private manned mission, with no significant government involvement.

Space junk that ESA demo mission intends to de-orbit as been struck by another piece of space junk

9:44 am

In a strange bit of irony, an abandoned payload adapter from a mission launched a decade ago that a European Space Agency (ESA) mission was planning on capturing and de-orbiting has been hit by another piece of space junk, creating additional bits debris around it.

The adapter is a conical-shaped leftover, roughly 250 pounds (113 kg) in mass, from a 2013 Vega launch that sent a small fleet of satellites into orbit. Space tracking systems found new objects nearby the adapter, which ESA learned about on Aug. 10. The objects are likely space debris from a “hypervelocity impact of a small, untracked object” that smacked into the payload adapter, the agency said. We may never know if the crashing object was natural or artificial, given it didn’t appear in tracking systems.

The ESA mission, dubbed Clearspace-1, intends to launch in 2026 and use four grappling arms to grasp the payload adapter, after which both shall be sent to burn up in the atmosphere. Its goal is to demonstrate technology for removing space junk. This event, creating extra debris pieces around the payload adaptor, puts a kink on that mission while also underlining the need for such technology.

Mission engineers now have three years to figure out what, if anything, they need to do to deal with the extra debris. The good news so far is that it appears the payload adapter remains intact, its orbit has not changed, and the surrounding debris appears small enough to pose “negligible” risk.

India successfully lands Vikram on the Moon

9:10 am


Click for interactive map.

India this morning successfully placed its Vikram lander, carrying its Pragyan rover, on the surface of the Moon in the high southern latitudes.

I have embedded the live stream below, cued to just before landing.

The next challenge is getting Pragyan to roll off Vikram, and spend the next two weeks exploring the nearby terrain. The mission of both it and Vikram is only planned to last through the daylight portion of the 28-day-long lunar day, so it is not expected for either to survive the lunar night. Both will make observations, but the main purpose of this mission has already been accomplished, demonstrating that India has the technological capability to land an unmanned spacecraft on another planet. That the landing was in the high southern latitudes added one extra challenge to the mission.
