China Taikonauts Zhai Zhigang and Wang Yaping completed their extravehicular activities (EVAs) and returned to the space station core module Tianhe in the early hours of Monday, Beijing time.
The two returned to the core module after 6.5 hours of spacewalking duties. Ye Guangfu remained in the cabin and supported the EVAs.
This was the third extravehicular mission conducted during the construction of China’s space station and the first by the Shenzhou-13 crew.
Zhai’s spacewalk signaled his second time performing an EVA. He completed China’s first spacewalk 13 years ago during the Shenzhou-7 mission. In this more recent outing, he installed “foot stoppers” and then performed the EVAs under the assistance of the station’s robotic arm.

“The device installed this time is mainly used for connecting the upper and lower parts of the robotic arm. We made this to prepare for the two parts to carry out combined operation. After being connected, the two parts can form a 15-meter-long robotic arm, which will have a wider working range,” Tang Zixin, monitor of the robotic arm engineering of the space station system at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation told China Central Television (CCTV).

Station orientation
“This time, the Tianhe core module has two cargo crafts docked at the two ends and a manned spacecraft docked radially. The whole structure has changed a lot. Therefore, to prepare for the EVAs, we made special adjustment involving the flying attitude, solar wings, and tilt angle of communication antenna. The core module’s flying attitude was especially designed for this time’s EVAs. The operation was very precise and accurate,” Zhu Guangchen, deputy chief designer of the space station system at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation told CCTV.
China launched the Shenzhou-13 crew on October 16, the trio of taikonauts on a six-month mission to construct its space station, expected to be completed by the end of next year.

New lab modules
China is preparing the launch of two lab modules, Wentian and Mengtian. They will first dock with the space station’s core module in the forward direction and then the mechanical arm will move them to both sides of the core module.
Before this milestone, the Shenzhou-13 crew will use the Tianzhou-2 cargo spacecraft to do a simulative test.
“Tianzhou-2 is now in front of our core module, and then will turn to the side of the core module by the mechanical arm to verify the process of transposition after Wentian module docks with the space station. This is a technique that we must master before the final ‘T’ shape was formed during the assembly phase of the space station,” said Li Xuedong, lead designer of the space station system with the China Aerospace Science and Technology Corporation.

The Tianzhou-2 cargo spacecraft is expected to complete its mission and undock from the space station early next year. After that, the Shenzhou-13 crew will also complete their mission and return to Earth.
When the Shenzhou-14 crew enters the space station, the country will launch the Wentian module that is outfitted with a special airlock capsule, providing a better environment for crew members to carry out spacewalks. That airlock is larger than the one now being used in the core module. It also has more equipment to facilitate EVAs, Li told CCTV.

Emergency practice
Earlier, the three Chinese astronauts in the under-construction Tiangong space station carried out an emergency evacuation exercise on a scenario of a crash caused by space debris.
China Central Television (CCTV) reported that the exercise started with an alarm for the loss of pressure in the space station. Astronaut Zhai Zhigang made judgments about the data of the pressure, while Ye Guangfu responded by opening the emergency gas cylinder to ensure that the pressure in the cabin remained stable.
Wang Yaping and Ye Guangfu soon closed the hatches of the two cargo crafts in a few minutes and evacuated to the return capsule of the Shenzhou-13.

Astronaut safety
“We have data criteria for the emergency management, such as the cabin pressure and its decline rate. The astronauts will open the emergency gas cylinder at first, and check where the leakage happens. If the core module is not leaking, they will go to check the spaceship. The astronauts need to close the hatches after ensuring the spaceship is fine,” said Wang Chunhui, deputy chief designer of astronaut system of the China Astronaut Research and Training Center.

“The design of the space station has set the highest requirements for the astronauts’ safety. We have all emergency preparedness for the pressure loss in the cabin, fire and other situations to ensure the life safety of the astronauts,” Wang told CCTV.
The three Chinese astronauts have been working and living in orbit after entering the core module on October 16.
The combination of China’s space station is formed by the Shenzhou-13 spaceship, Tianhe core module, and cargo craft Tianzhou-2 and Tianzhou-3.

Retro fire yourself back to the 1970’s.
It was a time of Soviet Union/United States Cold War, space race, one-upmanship histrionics.
In late March 1972, the Soviet Union’s Cosmos 482 was launched – an attempted Venus probe that ran afoul during its rocket-powered escape to that cloud-veiled world.
A big chunk of that failed craft remains in Earth orbit today as space junk.

Telescopic looks
Ralf Vandebergh of the Netherlands has been taking telescopic looks at the errant Cosmos 482 remains for numbers of years. He explains that, in late June 1972, a smaller object separated from the main spacecraft, thought to be the lander (descent craft), and catalogued as piece E.
Recently, Vandebergh re-appraised images he had taken of the spacecraft leftovers, stacking the best data he obtained from 2014 observations.
“I stacked data of 2 imaging sessions and I’m pretty sure now that there is a compact object – presumably the descent module as stated by experts,” Vandebergh told Inside Outer Space. “However the interesting thing is that there seems to be a fainter elongated part that seems attached to the compact object. It is just very hypothetical, but I thought it could be possible that what we see is the parachute that came out of the lander when it separated from the main spacecraft.”

Inevitable descent
The former Soviet Union’s Cosmos 482 was a sister probe to Venera 8. That spacecraft in July 1972 became the second craft to land successfully on the surface of Venus. It relayed data from Venus’ hellish surface for 50 minutes and 11 seconds before succumbing to the harsh planetary conditions.
Meanwhile, adrift around Earth and headed, eventually, for an Earth reentry is the lost-to-space Cosmos 482 wreckage.
One key question that intrigues satellite spotters is whether the out-of-action spacecraft still includes its Venus entry capsule.
That Soviet-style contraption was built to withstand the heat of diving into Venus’ cloud-veiled planet’s thick atmosphere. That Venus lander mass is pegged at 1,091 lbs. (495 kilograms) and carries significant thermal protection.

So could this piece of space junk survive its inevitable descent back to its home planet.
According to N2YO.com – a website dedicated to real time satellite tracking – the Cosmos 482 leftovers are circuiting Earth in an orbit that’s 129 miles (207.6 kilometers) by 1,284 miles (2,065.7 kilometers).
Exactly when and where the wayward hardware could plummet back to Earth is uncertain. Some analysts peg its reentry between 2023 and late 2026.

Settling in settings
“The Shenzhou-13 taikonauts have finished their settling in settings. And they have unpacked the new extravehicular suit we just sent up with the Tianzhou-3 cargo craft and completed various tests to make sure the space suit is well set for extravehicular activities,” said Wu Hao, an assistant researcher of the China Astronaut Research and Training Center, who specializes in training space crews for extravehicular activities.
The Shenzhou-13 team have successfully transferred supplies from the Tianzhou cargo crafts, maintained the space station combination in a good condition, unpacked and tested the new extravehicular spacesuit, conducted medical examinations, done weightless exercises, carried out some regular scientific experiments, and prepared for such emergency operations as evacuation and first aid, said the CMSA.
Target: new duration record
Launched on October 16, the crew will stay in orbit for six months, setting a new duration record for China’s crewed space missions.
A recently released set of videos spotlights life onboard the orbiting outpost, including the crew carrying out a microbiological analysis of their drinking water.

Mixed gender, nationalities
Representing a mixed gender and nationality of the crew, the international crew of the SIRIUS-21 mission are: Oleg Blinov (Russia), Victoria Kirichenko (Russia), Ekaterina Karjakina (Russia), William Brown (USA), Ashley Kowalski (USA) and Saleh Omar al Ameri (UAE).
During the experiment simulating a flight to the Moon, it is planned to collect scientific data on a number of problems expeditionary space crews will face, such as:
- sensory deprivation, monotony, limited social contacts, limited living space and managed habitat
- factors of autonomous interplanetary flight, including limiting the resources of the expedition and extravehicular activities on the planet’s surface
- professional activities of the crew (docking of transport ships, landing of the lunar module, control of robotic equipment)
- communication delay up to 5 minutes one way
Earlier stages
The previous two stages of the experiment – SIRIUS-17 and SIRIUS-19 – were carried out in 2017 and 2019, respectively.

SIRIUS analog missions assist NASA in gaining knowledge about the physiological and psychological “exploration stresses” of remoteness and confinement in humans – all in preparation for sustained Artemis expeditions to the Moon and on-the-horizon flight of crews to Mars.
Composition of the crew includes crew commander, flight engineer, crew doctor and three researchers. The activities of the crew during the experiment are based on the basic provisions of the Code of Professional Ethics of Cosmonauts of the Russian Federation and the Code of Conduct for the International Space Station crew.

The Defense Department today released its annual report on military and security developments involving China, commonly referred to as the China Military Power Report.
This newly issued report discusses China’s space ambitions:
“The PRC’s [People’s Republic of China] space enterprise continues to mature rapidly and Beijing has devoted significant economic and political resources to growing all aspects of its space program, from military space applications to civil applications such as profit-generating launches, scientific endeavors, and space exploration.”
The report notes the inaugural launch of a reusable PRC Space Plane, explaining:
“In early September, the PRC became the third country to successfully launch and recover a space plane, after
the United States and the Soviet Union. The space plane spent about two days in space before releasing a second object, de-orbiting, and landing at an airfield in Western China. The second object remains on orbit. Beijing has not released any information on the mission beyond calling it a “reusable experimental spacecraft.”

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3286 duties.
Reports Ken Herkenhoff, a planetary geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona, the robot’s Sol 3285 drive went well.
The rover has a good view of nearby outcrops, so the science team had a lot of potential drill and contact science targets to discuss, Herkenhoff adds. “We sent a prioritized list of drive targets to the rover planners, and ultimately selected a low-lying outcrop.”

Planning day
“Although the time available before new data must be relayed to Earth was limited today, we were able to plan contact science on a nearby rock target called “Dumbuck” and some remote sensing observations as well,” Herkenhoff notes. “It was a busy and sometime hectic planning day for the team…but the effort was worth it because the final plan is excellent.”

After the Alpha Particle X-Ray Spectrometer (APXS) and the Mars Hand Lens Imager (MAHLI) examine Dumbuck, the rover’s Chemistry and Camera (ChemCam) will shoot its laser at a nearby nodule-rich bedrock target named “Fallen Stack,” Herkenhoff reports, “to look for compositional variations among the nodules and surrounding bedrock.”

Drill site mosaics
After Curiosity’s Right Mastcam documents the laser spots, several Mastcam stereo mosaics are planned of the drill site for context, of an outcrop to the west dubbed “Bellevue,” and an outcrop uphill named “Cliffs of Hallaig.”

“Mastcam stereo mosaics will also be acquired on a couple targets that had been imaged before, “Coylton Rocking Stone” and “Ciuff Hill,” from our new viewpoint,” Herkenhoff says.
After the drive to the new drill site, in addition to the standard post-drive imaging, Navcam and Mastcam will take mosaics of much of the terrain surrounding Curiosity to enable an upcoming, detailed target selection.
Navcam will also search for clouds and the robot’s Mars Descent Imager (MARDI) will image the surface behind the left front wheel during twilight.

It is a fact that the Sun never sets in space.
Likewise, the idea of harvesting solar energy via power beaming satellites is a long-coming dawn of a glittery thought to feed an energy-ravenous Earth.
Technical feasibility, cost and economics of space-based solar power as a novel generation technology could support the UK to achieve net-zero emissions by 2050, according to a leading British systems, engineering and technology company.

That reflection has fomented for decades but is now garnering new looks – both in the U.S. and abroad, including Chinese technologists, experts in Japan, and researchers within the European Space Agency and the United Kingdom Space Agency.
Should the long-standing vision for space solar power (SSP) as a sustainable energy alternative be revisited in light of recent advances in technologies?
