Four Mice Carrying Key Experimental Data Return to Earth | China Space Station

Four Mice Carrying Key Experimental Data Return to Earth | China Space Station

Concluding a nearly two-week mission aboard China's space station, four mice have returned to Earth on November 14, 2025, with the three astronauts of China's Shenzhou-20 mission, bringing back highly valuable experimental data.

The return capsule of the Shenzhou-21 spaceship, carrying the Shenzhou-20 astronauts Chen Dong, Chen Zhongrui and Wang Jie, touched down at the Dongfeng landing site in north China's Inner Mongolia Autonomous Region on Friday.

Weighing 46.67 kilograms and collected from 26 experiment projects, these samples consist of nine from life experiments, three from combustion experiments, and 32 material samples.

Later, scientists will conduct biological analyses on the life experiment samples, carrying out multi-dimensional research on the impact of the microgravity environment on the body from cells to 3D tissues, and studying key relevant biological mechanisms and intervention targets, so as to provide new clues for the prevention and intervention of related diseases.

For the combustion experiment samples, researchers will study the generation characteristics of nano-carbon particles. The research results are expected to offer technical support for the development of new energy systems, space fire-prevention technologies, and the production of advanced functional nano-carbon materials.

For the material samples, researchers will carry out tests and analyses on their morphology and chemical composition to study the effect of gravity on material growth and component segregation. These studies will contribute to the future space application of high-performance solar cell protective materials and lunar base construction materials.

"China's in-orbit experiments have been carried out continuously over the long term. Currently, the space laboratory has entered a very normal and fully productive operating state. We hope through these experimental samples and subsequent ground-based research, we can further follow up and achieve more original scientific results with international influence," said Zhang Lu, researcher of the Technology and Engineering Center for Space Utilization under the Chinese Academy of Sciences.

Vibrant Gaseous Ribbons: The Veil Supernova Remnant in Cygnus | Hubble | STScI

Vibrant Gaseous Ribbons: The Veil Supernova Remnant in Cygnus | Hubble STScI

This 3-D visualization flies across a small portion of the Veil Nebula as photographed by the Hubble Space Telescope. This region is a small part of a huge expanding remnant from a star that exploded many thousands of years ago. Hubble resolves tangled rope-like filaments of glowing gases. They have been shocked and heated by colliding with cooler, denser interstellar gas. 

The 3-D model has been created for illustrative purposes and shows that the giant bubble of gas has a thin, rippled surface. It also highlights that the emission from different chemical elements arises from different layers of gas within the nebula. In the imagery, emission from Sulfur, Hydrogen, and Oxygen are shown in red, green, and blue, respectively.

Florida "Northern Lights" & Northern Taurid Meteor

Florida "Northern Lights" & Northern Taurid Meteor

Northern lights have come to Florida skies. The brilliant streak of a Northern Taurid meteor flashes through the starry night sky above the beach in this sea and skyscape, captured from Shired Island, Florida, on November 11, 2025. Meteors from the annual Northern Taurid meteor shower are expected this time of year. However, the digital camera exposure also records the shimmering glow of aurora, a phenomenon more often seen from our fair planet's higher geographical latitudes. Also known as aurora borealis, these northern lights are part of recent, wide spread auroral activity caused by strong geomagnetic storms. In the last few days, these storms have been triggered by multiple Earth impacting coronal mass ejections (CMEs) and intense solar activity.

The Taurids are an annual meteor shower, associated with the comet Encke. The Taurids are actually two separate showers, with a Southern and a Northern component. The Southern Taurids originated from Comet Encke, while the Northern Taurids originated from the asteroid 2004 TG10, possibly a large fragment of Encke due to its similar orbital parameters. They are named after their radiant point in the constellation Taurus, where they are seen to come from in the sky. Because of their occurrence in late October and early November, they are also called Halloween fireballs. Since 2P/Encke is such a short period comet, the meteors have the slowest impact speed of the annual well-known meteor showers.

Auroras happen when charged particles from the Sun interact with Earth's magnetic field, creating dazzling light shows in the sky. The aurora borealis, also known as the northern lights, occurs in an upper layer of Earth’s atmosphere called the ionosphere.

Fireball over Arizona

Fireball over Arizona

Photographer Ren Turley: "Fireball last night over Sedona was so bright night turned to day for a heartbeat."

In astronomy, fireballs, also known as bolides, are exceptionally bright meteors that, like all meteors, heat up when they enter Earth's atmosphere at high velocities and leave a trail of glowing material in the sky. Meteors are classified as fireballs when they shine brighter than the planets—an apparent magnitude of –4 or brighter. 

A fireball is a very bright meteorone at least as bright as Venus and possibly brighter than even a full Moon. Fireballs are rareif you see one you are likely to remember it for your whole life. Physically, a fireball is a small rock that originated from an asteroid or comet that typically leaves a fading smoke trail of gas and dust as it shoots through the Earth's atmosphere. It is unlikely that any single large ground strike occurredmuch of the rock likely vaporized as it broke up into many small pieces.

Capsule Carrying Shenzhou-20 Crew Lands in North China | China Space Station

Capsule Carrying Shenzhou-20 Crew Lands in North China | China Space Station

The return capsule of the Shenzhou-21 spacecraft, carrying the Shenzhou-20 astronauts Chen Dong, Chen Zhongrui and Wang Jie, touched down at the Dongfeng landing site in north China's Inner Mongolia Autonomous Region on November 14.

At 11:14 Beijing Time (0314 GMT), the Shenzhou-21 crewed spacecraft undocked from the space station combination. At 14:49 Beijing time (0649 GMT), the Beijing Aerospace Control Center issued a return command through the ground station, and the orbital capsule of the Shenzhou-21 spacecraft separated from the return capsule.

The brake engine then ignited, and the Shenzhou-21 return capsule separated from the propulsion capsule. The return capsule touched down at the Dongfeng landing site at 16:40 Beijing time (0840 GMT), the China Manned Space Agency (CMSA) said.

The returned astronauts are in good physical condition, according to the medical staff on site.

The Shenzhou-20 crew was sent into space from the Jiuquan Satellite Launch Center in northwest China on April 24, 2025.

Their return, originally scheduled for Nov 5, was postponed due to safety concerns. Tiny cracks were found in the viewport window of the Shenzhou-20 manned spacecraft's return capsule, which are most probably caused by external impact from space debris, according to the CMSA.

The agency said the Shenzhou-20 spacecraft does not meet the requirements for the astronauts' safe return and will remain in orbit to continue the relevant experiments.

Prior to Friday's return, the crew handed over the space station to the Shenzhou-21 astronauts who got on board on Nov 1.

The Shenzhou-22 spacecraft will be launched at an appropriate time in the future, said the CMSA.

The return capsule of China's Shenzhou-21 spacecraft, carrying the Shenzhou-20 crew, touched down at the Dongfeng landing site in north China's Inner Mongolia Autonomous Region at 4:40 p.m. (Beijing Time) on Friday, November 14, 2025, according to the China Manned Space Agency (CMSA).

At 2:49 p.m., the Beijing Aerospace Flight Control Center issued the return command via ground tracking stations and the Shenzhou-21 spacecraft undocked from the space station combination.

After the braking engine fired up, the return capsule separated from the propulsion module and touched down successfully. Search-and-rescue teams quickly located the return capsule and reached the landing site. Medical staff confirmed that Shenzhou-20 crew members Chen Dong, Chen Zhongrui and Wang Jie were in good physical condition.

At 5:21 p.m., all three Chinese astronauts, or taikonauts, exited the capsule safely. 

The crew spent 204 days in orbit, setting a new record for the longest stay by a single Chinese crew. 

During the mission, they completed four spacewalks and multiple cargo transfer operations. Working closely with researchers on the ground, they conducted a wide range of scientific experiments spanning microgravity physics, space materials science, life sciences, aerospace medicine and space technology.

After exiting the capsule, Chen Dong, the commander of the mission, said he felt "very grounded" returning home aboard the Shenzhou-21 spacecraft. He said that the road of human space exploration is not smooth but full of difficulties and challenges.

"And that is exactly why we choose to take it. This mission was both a training opportunity and a test. I'm very proud that we successfully completed it and that China's space program has withstood the test," Chen said.

Chen Zhongrui said, "We departed from here on April 24 and flew into space for a six-month mission. With the unity of our crew and the close coordination between space and ground, we completed all our tasks. I feel especially happy and fortunate."

Wang Jie said, "After half a year, returning safely to Earth and feeling gravity again is truly wonderful. This journey to space was not only a dream come true but also a challenging and arduous process of growth. Our success and honor embody the effort and wisdom of all space personnel and reflect the remarkable progress our country has made in space exploration."

After completing the Shenzhou-20 crewed mission, Chen Dong became the first taikonaut whose cumulative time in orbit had exceeded 400 days, and he is also the Chinese astronaut who has carried out the most spacewalks to date. The maiden flights of Chen Zhongrui and Wang Jie were also successfully completed.

The return of the Shenzhou-20 crew, originally scheduled for November 5, was postponed after slight cracks were detected on the window of the Shenzhou-20 spacecraft's return capsule, believed to be caused by a suspected impact from tiny space debris.

"This is the first time we met this uncertainty... but this is also a very good example, showing that we always take the safety of our taikonauts as the top priority," Yang Yuguang, chairman of the Space Transportation Committee of the International Astronautical Federation, told CGTN in a special program ahead of the Shenzhou-20 crew's landing.

The cracks on the window were discovered during a routine inspection of the spacecraft's condition, said Sui Yanan, associate professor at the School of Aerospace Engineering at Tsinghua University.

"A crack on the window is not a very big thing from a mechanical point of view, but still there are unknown safety risks," Sui said, adding that during the journey back to Earth, the cracks could expand due to high temperature and pressure.

"Even [if] the window broke completely, there [are] ways to guarantee the safety of the taikonauts, but we don't want those things to happen," Sui said.

After careful consideration, China decided to use the Shenzhou-21 spacecraft to bring the crew home.

"We always have a backup spaceship standing in the Jiuquan Satellite Launch Center. That's a system-level backup to ensure the safety of our taikonauts," Yang added.

A batch of space science experiment samples returned safely aboard the Shenzhou-21 spacecraft. They include nine types of life-science samples, such as laboratory mice, zebrafish, macrophages and hepatocytes. Also on board were various material samples, including tungsten-hafnium alloys, soft magnetic materials, new thermal control coatings and protective components for thin-film solar cells used in space. In addition, three types of combustion experiment samples, burners, soot collection plates and collection caps were brought back.

Shenzhou-21 Spacecraft Undocking Before Crew's Earth Return | China Space Station

China's Shenzhou-21 crewed spacecraft undocked from the space station combination at 11:14 on November 14, 2025, (Beijing Time) to send the Shenzhou-20 astronauts back to Earth, according to the China Manned Space Agency (CMSA).

The return capsule of the Shenzhou-21 spacecraft, carrying the Shenzhou-20 astronauts Chen Dong, Chen Zhongrui and Wang Jie, touched down at the Dongfeng landing site in north China's Inner Mongolia Autonomous Region on Friday, safely taking the three-member crew back home.

During a talk program of the China Media Group (CMG), Zhou Yaqiang, a technology official from the China Manned Space Agency (CMSA), explained the reasons for using the Shenzhou-21 instead of launching a new spacecraft to take the astronauts back to Earth.

"There are two main factors. First, the technical specifications of the Shenzhou-21 spacecraft are consistent with those of the Shenzhou-20 spacecraft, and the Shenzhou-20 crew had previously undergone trainings on the Shenzhou-21 spacecraft, making them quite familiar with it. In contrast, the instruments on the Shenzhou-22 spacecraft have been optimized and improved. Second, the Shenzhou-20 crew had completed their scheduled in-orbit missions, and we wanted to bring them back to the Earth as quickly as possible. Ultimately, it was all to ensure the return mission is flawless and that the astronauts are absolutely safe," said Zhou.

Li Guangsu, an astronaut from the Shenzhou-18 crewed mission, provided insight into the preparations Shenzhou-20 crew made for a safe and comfortable return aboard the Shenzhou-21 spacecraft.

"For astronauts, the process of returning aboard a different spacecraft this time involves transferring relevant materials from the Shenzhou-20 spacecraft to the Shenzhou-21 spacecraft. Another crucial task is replacing the seat cushions on the Shenzhou-21 spacecraft, as these cushions are custom-made to fit each astronaut's individual measurements," Li said.

The Shenzhou-20 crew was sent into space from the Jiuquan Satellite Launch Center in northwest China on April 24.

Their return, originally scheduled for Nov. 5, was postponed due to a suspected impact to the Shenzhou-20 spacecraft from tiny space debris, according to the CMSA.

In response, emergency protocols were immediately activated, and a comprehensive simulation analysis, testing and safety assessment of the Shenzhou-20 crewed spacecraft were conducted to determine the safest course for the astronauts' return.

Following the review, the CMSA announced that the Shenzhou-20 spacecraft no longer meets the stringent safety standards required for re-entry. As a result, it will remain in orbit to continue the relevant experiments.

Next, the Shenzhou-22 spacecraft will be launched at an appropriate time, said the CMSA.
