China today released three new images from its Zhurong Mars rover, showing that since their last release in late June the rover has traveled about 1,000 feet to the south to reach the parachute and backshell (or entry capsule), both released just before landing.

The image to the right, cropped and reduced to post here, is the color panorama from that release, looking north. According to a translation of the Chinese press release, provided at this Space.com report, the image shows:

“The complete back cover structure after aerodynamic ablation, the attitude control engine diversion hole on the back cover is clearly identifiable,”

Below is an annotated orbital picture of this location taken by Mars Reconnaissance Orbiter (MRO) in mid-June.

China launches 5 military reconnaissance satellites

9:37 am

Using its Long March 6 rocket, China today successfully launched five military reconnaissance satellites.

This is China’s fourth successful launch in the past week.

Though this newer rocket’s first stage does not use toxic hypergolic fuels — China’s older rockets — that first stage still crashes in China after its job is done and it falls to Earth. No word on whether it landed near inhabited regions.

The leaders in the 2021 launch race:

22 China
20 SpaceX
11 Russia
3 Northrop Grumman

The U.S. still leads China 29 to 22 in the national rankings.

China targets 2024 for next lunar sample return mission

9:42 am

The new colonial movement: China’s next robotic lunar sample return mission, called Chang’e-6 and targeted for a 2024 launch, will also attempt to bring back the first samples from the far side of the Moon.

Hu Hao, chief engineer of the China Lunar Exploration and Space Engineering Center, announced in a statement released on China’s national space day in April this year that the Chang’e 6 probe, consisting of an orbiter, lander, lunar ascent vehicle and reentry capsule, will target the South Pole-Aitken (SPA) basin.The SPA basin is a colossal, ancient impact crater roughly 1,550 miles (2,500 kilometers) in diameter that covers almost a quarter of the moon’s far side. The impact basin, considered to be the oldest on the moon, holds vital clues about the history of the moon and the solar system, according to a new report.

The precise spot for landing has not been revealed. Since the basin is so large and covers the Moon’s south pole, the mission could land in that region where ice is thought to possibly exist in the permanently shadowed floors of some craters. Whether they would attempt a landing in one of those craters is presently unknown, though unlikely because of the technical challenge.

China launches communications satellite for space effort

8:15 pm

Using a Long March 3C rocket China today successfully launched a communications satellite for use by its manned space missions and its space station, similar to the TDRS satellites used by NASA for similar purposes.

This satellite is the fifth such satellite launched, and is likely intended to enhance communications between the ground and China’s new space station.

No word on where the first stage crashed, or whether it landed near habitable areas.

The leaders in the 2021 launch race:

21 China
20 SpaceX
11 Russia
3 Northrop Grumman

The U.S. still leads China 29 to 21 in the national rankings.

Today’s blacklisted American: YouTube blacklists group exposing Chinese genocide in its Xinjiang region

12:12 pm

The Bill of Rights cancelled on YouTube
No free speech allowed on YouTube.

Today’s blacklisting victim is not really an American, but since it is an American company doing the blacklisting I think the story is applicable. It appears Google-owned YouTube has decided to remove videos on the Atajurt Kazakh Human Rights’ channel that expose the genocide and ethnic cleansing that China is doing to as many as a million people in its Xinjiang region.

Atajurt Kazakh Human Rights’ channel has published nearly 11,000 videos on YouTube totaling over 120 million views since 2017, thousands of which feature people speaking to camera about relatives they say have disappeared without a trace in China’s Xinjiang region, where UN experts and rights groups estimate over a million people have been detained in recent years.

On June 15, the channel was blocked for violating YouTube’s guidelines, according to a screenshot seen by Reuters, after twelve of its videos had been reported for breaching its ‘cyberbullying and harassment’ policy.

The channel’s administrators had appealed the blocking of all twelve videos between April and June, with some reinstated – but YouTube did not provide an explanation as to why others were kept out of public view, the administrators told Reuters.

Following inquiries from Reuters as to why the channel was removed, YouTube restored it, explaining that it had received multiple so-called ‘strikes’ for videos which contained people holding up ID cards to prove they were related to the missing, violating a YouTube policy which prohibits personally identifiable information from appearing in its content. They reinstated the channel on June 18 but asked Atajurt to blur the IDs.

China releases more images & videos from Zhurong

China today released a new panorama as well as several videos taken by its Mars rover Zhurong.

The videos show the rover’s landing as well as two short videos taken from the remote camera it had dropped off shortly after deployment from its lander, the first showing the rover moving away and the second showing it turning in place.. China also released sound recorded during that deployment, as the rover rolled down the ramps. The sound was of course enhanced, but it does allow scientists to learn something about the atmosphere of Mars.

The image above is a cropped section from the panorama. The map to the right, taken on June 11th by the high resolution camera on Mars Reconnaissance Orbiter (MRO), has been annotated by me to show the area I think is seen by this section of that panorama, looking due north. (For a higher resolution version that clearly shows the rover’s tracks since leaving the lander, go here.)

Chinese official outlines that country’s Mars exploration plan

10:02 am

The new colonial movement: According to an official from China’s prime rocket manufacturer, China is now beginning to plan for the manned exploration of Mars.

Wang Xiaojun, head of the state-owned China Academy of Launch Vehicle Technology (CALT), outlined the plans in his speech themed “The Space Transportation System of Human Mars Exploration” at the Global Space Exploration Conference (GLEX 2021) via a virtual link, the academy told the Global Times on Wednesday.

After reviewing the successful mission of the Tianwen-1 probe mission, the country’s first interplanetary exploration that achieved a successful orbiting, landing and roving the Red Planet all in one go, Wang introduced the three-step plan for future Mars expedition.

At the primary stage, or the technology preparation phase, androids will be launched whose mission include a Mars sample return mission and the exploration of a Mars base site. Next will be a manned Mars mission, and the building of a Mars base will be carried out. The third stage will be attempting shuttling large scale Earth-Mars cargo fleet and large scale development of the Red Planet.

The timetable for such mission launches will be 2033, 2035, 2037, 2041 and 2043, among others, the academy said.

While this is very far in the future, you can’t make it happen if you don’t get started early. China’s government is clearly looking at getting started, and appears to be following the same timetable approach it did for its space station. They began planning it about a decade ago, and are now launching and assembling it.

China’s decision to aim for Mars proves that the competition to get there is heating up considerably, and is likely their response to Elon Musk’s determined effort to make it possible.

A detailed look at Russia’s suffering and shrinking space program

9:46 am

Link here. The article starts off outlining Russia’s deepening inability to produce the computer chips it needs for its space effort, acerbated by sanctions imposed against that country because of its invasion of the Ukraine. It then goes on to describe the program’s overall financial problems, including its shrinking commercial market share resulting in a significant drop in income.

The article’s conclusion is stark:

If Moscow is unable to reach a new space deal with Washington, it will need to reconsider its space policy. But Russia has little wiggle room to increase federal spending on space activities to boost the industry. For instance, the government’s space program for 2016–2025 received $11.1 billion in 2016–2020 and will obtain another $10.2 billion in 2021–2025. The federal program for launch sites (2017–2025) secured $1.4 billion in 2017–2020 and will take in a further $2.83 billion in 2021–2025 (Economy.gov.ru, 2016–2021). The 2012–2020 GLONASS program received almost $5.1 billion, and $6.45 billion more is planned for the GLONASS program in 2021–2030 (RBC, December 21, 2020). Thus, without an international cooperation deal, and as long as Western sanctions are maintained, prospects for Russia’s space industry look bleak.

Russia has recently been working to establish a partnership with China and its effort to build a space station and a lunar base. That partnership however is not likely to provide Russia with any cash, which means the deal is an empty one. While China will continue to proceed to the Moon, I doubt Russia will follow with much.

It has also been trying to rework its American partnership, with Rogozin acting alternatively as a good guy/bad guy in public declarations. Since Russia opposes the Artemis Accords, and the Biden administration is continuing the Trump administration’s demand that all partners in the Artemis program agree to these accords, those negotiations are not likely to get Russia much. Moreover, NASA policy today is to feed money to American private companies so that they can grow, not feed money to Russia so that it can prosper.

Until Russia starts allowing free competition and private enterprise, outside the control of Roscosmos and the government, do not expect much of this Russian bad news to change. While China might strictly supervise the goals of its private space companies, it still encourages them to compete and innovate, and even fail. Russia not only strictly supervises, it also forbids any new startups from forming, as they might do harm to already established players. The result is no new innovation, and no new products of any real value.

Zhurong’s travels during first three weeks on Mars

9:31 am

Zhurong's travels through June 11th
Click for full image.

The science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) today released a new image showing the path that China’s rover , Zhurong, has taken from its landing on May 14th through June 11th.

The photo to the right, cropped and reduced to post here, is that photo. If you look close you can see the rover’s track skirting the edge of the bright blast mark put on the surface by the lander’s engines during touchdown. Though my scale bar is approximate, it does show that in those four weeks the rover traveled about 150 to 200 feet. However, half of that distance was crossed in the five days from June 6th to June 11th (as shown by the two different MRO images at these links), which means the pace is picking up.

The rover’s nominal three-month mission ends in mid-August, only two months from now. However, none of us should be surprised if the mission gets extended for as long as the rover continues to function.

Hubble remains out of commission, with no repair date in sight

9:32 am

According to a statement to Space.com provided by the engineers trying to fix the Hubble Space Telescope, “there is no definitive timeline for bringing the computer back online.”

The Hubble operations team is working to solve the payload computer issue onboard the Hubble Space Telescope. The team is working to collect all the data available to them to isolate the problem and determine the best path forward for bringing the computer back to operations. At this time, there is no definitive timeline for bringing the computer back online. However, the team has multiple options available to them and are working to find the best solution to return the telescope to science operations as soon as possible.

…Assuming that this problem is corrected via one of the many options available to the operations team, Hubble is expected to continue yielding amazing discoveries into the late 2020s or beyond,” the operations team at NASA’s Goddard Space Flight Center in Maryland told Space.com in an email. However, “there is no definitive timeline yet as to when this will be completed, tested and brought back to operational status,

I gather from this that they do have options to might fix the problem, but they have also found the problem to be more complex than expected.

While I honestly am confident these engineers can bring the telescope back to life, we must all be prepared for the strong possibility that this might be the moment when such a repair is impossible. If so, our vision of the heavens will once again be blinded by the poor vision available to us from inside the Earth’s atmosphere. And that vision will not be cleared in the foreseeable future by an American or western optical space telescope, as none are being designed, no less built.

The Chinese however are building one, for their purposes, which will be better than Hubble and is set to launch within the next few years to fly in formation with their new space station, close by so that astronauts can do repairs if necessary.
