NASA Astronaut Profile of Chris Williams: Pre-flight | International Space Station

NASA Astronaut Profile of Chris Williams: Pre-flight | International Space Station

Long before he became a NASA astronaut, Chris Williams learned through his time in Boy Scouts a very valuable lesson . . . “you can do a whole lot more than you think you can.” The variety of accomplishments and skills acquired as a scout set a foundation of learning throughout Williams’ life, as he pursued a career in astrophysics, switched gears to become a medical physicist for cancer therapy, and now as an astronaut as he trained for his mission to the International Space Station.

NASA astronaut Chris Williams can be seen here training for his first mission to the International Space Station. He will launch aboard the Russian Soyuz MS-28 spacecraft with Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev of Russia, becoming a flight engineer on Expedition 73/74 after arriving at the station. During his approximately eight-month mission, Williams will conduct numerous scientific experiments and technology demonstrations, and help maintain the space station.

At the Baikonur Cosmodrome in Kazakhstan, the Soyuz MS-28 prime and backup crews completed final pre-flight training ahead of the scheduled Nov. 27, 2025, launch of NASA’s Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikayev for a planned eight-month mission to the International Space Station (ISS). The training activities that took place Nov. 11 through Nov. 21 include the rollout of the Soyuz 2.1a launch vehicle to its launch pad in Baikonur Nov. 24.

Journey to The Butterfly Nebula in Scorpius | Gemini South Telescope | NOIRLab

Journey to The Butterfly Nebula in Scorpius | Gemini South Telescope | NOIRLab

To celebrate 25 years since the completion of the International Gemini Observatory, students in Chile voted for the Gemini South telescope to image the NGC 6302—a billowing planetary nebula that resembles a cosmic butterfly. The International Gemini Observatory is partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab.

NGC 6302 is a bipolar planetary nebula that lies between 2,500 and 3,800 light-years away in the constellation Scorpius. Sources report various dates of discovery, but credit typically goes to a 1907 study by American astronomer Edward E. Barnard, though Scottish astronomer James Dunlop may have discovered it in 1826. Its official name is NGC 6302, but it is also referred to as the Butterfly Nebula, Bug Nebula, or Caldwell 69.

A planetary nebula is a type of emission nebula consisting of a massive star near the end of its life that is expelling material, surrounded by an expanding, glowing shell of ionized gas. Typically, these mesmerizing structures have a planet-like round shape. This is why they were named ‘planetary nebulae’ by the early astronomers who observed them through their telescopes.

You may notice, though, that the Butterfly Nebula does not resemble a round planet, but instead a "winged creature caught mid-flight." The formation of this unique structure is driven by a star at the nebula’s center that is casting off layers of gas and dust as it nears the end of its life.

Shenzhou-22 Launch Highlights Space Emergency Readiness | China Space Station

Shenzhou-22 Launch Highlights Space Emergency Readiness | China Space Station

The successful launch of China's Shenzhou-22 spacecraft on November 25, 2025, demonstrated the Long March-2F carrier rocket's rapid-response capability for space station emergencies. It took only 16 days for the China Manned Space Agency (CMSA) to respond after tiny cracks were found in the viewport window of the Shenzhou-20 crewed spacecraft's return capsule docked at the China Space Station, most probably caused by an external impact from space debris.

The replacement Shenzhou-22 spacecraft was launched from the Jiuquan Satellite Launch Center in northwest China, marking the first emergency launch mission in the country's crewed space program.

The country introduced the "one launch, one on standby" arrangement, a rolling backup system for the Long March-2F as early as the launch of the Shenzhou-12 mission, with the backup rocket fully prepared to launch on short notice should the space station require urgent assistance. Tuesday's mission marked the first time this emergency mechanism was put into actual use.

Under this emergency scheme, there are always a standby Long March-2F rocket and a standby Shenzhou spacecraft inside a dedicated facility at the Jiuquan Satellite Launch Center. The Long March-2F Y22 rocket used in the mission was such a backup vehicle, maintained in full readiness for precisely such emergency deployment.

"We ensure that one rocket is always in a ready-to-launch state. All work on this rocket is conducted as if it were performing a formal task. Tasks such as rollout and quality verification are all carried out in accordance with the standards for official tasks. By completing much of the work in advance, we can shorten the preparation window when an actual emergency need rises," said Zeng Yaoxiang, an engineer at the China Aerospace Science and Technology Corporation (CASC).

According to Zeng, the team reduced a normal test-to-launch cycle of more than 30 days to just 16, making the standby rocket ready to launch.

He said the mission was not only a test of the rocket's reliability but also a demanding challenge for the team's coordination and workflow optimization.

"The whole period from tests to launch is 16 days, which is a very short window. It requires full concentration and strict adherence to the plan, and uncompromising quality control," Zeng said.

Although Shenzhou-22 is an uncrewed spacecraft, the rocket retained its full crewed-mission configuration, including the escape tower, ensuring it could undertake a manned emergency rescue at any moment.

Meanwhile, the next rocket in the series, the Long March-2F Y23, is undergoing assembly and test in Beijing. It will be transferred to the launch site upon completion of related work and will be on standby status for emergency response following the Shenzhou-22 mission.

How to Eat in Space | Artemis II Moon Mission | NASA's Johnson Space Center

How to Eat in Space | Artemis II Moon Mission | NASA's Johnson Space Center

During their mission around the Moon and back, the Artemis II crew will need to be nourished inside their Orion spacecraft. The food the four astronauts will eat will play a key role in maintaining their health and ensuring they can perform their mission objectives to the best of their abilities. Long before launch, teams at Johnson Space Center prepare so that the crew has everything they need to enjoy their “around-the-Moon-meals.”

It starts with Johnson’s Space Food Systems Laboratory, which supports the development and production of space food, menus, packaging, and food-related hardware for all NASA programs, including Artemis. The crew also spends time practicing how they will use equipment aboard Orion to rehydrate and warm their food inside a full-size Orion mockup at Johnson’s Space Vehicle Mockup Facility. During the mission, the crew will use a potable water dispenser to rehydrate their chosen food and drink packages and a briefcase-style food warmer for warming them up.

This is how NASA’s Artemis II astronauts will eat in space.

Astronauts Deliver American Thanksgiving Message for 2025 | International Space Station

Astronauts Deliver American Thanksgiving Message for 2025 | International Space Station

Aboard the International Space Station, NASA Expedition 73 crew members Zena Cardman, Mike Fincke, Jonny Kim, and JAXA astronaut Kimiya Yui share reflections on life and work aboard the orbital outpost as part of a prerecorded Thanksgiving message.

The four astronauts are in the middle of a long duration mission, living and working aboard the microgravity laboratory. The goal of their mission is to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis program.

Thanksgiving is a federal holiday in the United States celebrated on the fourth Thursday of November (the uniform date countrywide since 1941). The earliest Thanksgiving can occur is November 22; the latest is November 28. Outside the United States, it is called American Thanksgiving to distinguish it from the Canadian holiday of the same name and related celebrations in other regions.

Southern Lights | International Space Station

Southern Lights | International Space Station

Earth auroras are assigned names based on the pole where they occur. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth.

NASA & NOAA 2025 Ozone Hole Update | Goddard Space Flight Center

NASA & NOAA 2025 Ozone Hole Update | Goddard Space Flight Center

This year, the ozone hole over Antarctica reached its annual maximum extent on Sept. 9th, 2025, with an area of 8.83 million square miles (22.86 million square kilometers.) The average size of the ozone hole between Sept. 7 and Oct. 13 this year was the 5th-smallest since 1992—when the Montreal Protocol began to take effect.

The improvement is due to a combination of continuing declines in harmful chlorofluorocarbon (CFC) chemicals.

The ozone-rich layer high in the atmosphere acts as a planetary sunscreen that helps shield us from harmful ultraviolet (UV) radiation from the Sun. Areas with depleted ozone allow more UV radiation to reach Earth's surface, resulting in increased cases of skin cancer and cataracts. Excessive exposure to UV light can also reduce agricultural yields as well as damage aquatic plants and animals in vital ecosystems.

Scientists were alarmed in the 1970s at the prospect that CFCs could eat away at atmospheric ozone. By the mid-1980s, the ozone layer had been depleted so much that a broad swath of the Antarctic stratosphere was essentially devoid of ozone by early October each year. Sources of damaging CFCs included coolants in refrigerators and air conditioners, as well as aerosols in hairspray, antiperspirant, and spray paint. Harmful chemicals were also released in the manufacture of insulating foams and as components of industrial fire suppression systems.

The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. It was agreed on September 16, 1987, and entered into force on January 1, 1989. Since then, it has undergone nine revisions, in 1990 (London), 1991 (Nairobi), 1992 (Copenhagen), 1993 (Bangkok), 1995 (Vienna), 1997 (Montreal), 1999 (Beijing) and 2016 (Kigali).

Countries worldwide agreed to replace the chemicals with more environmentally friendly alternatives by 2010. The release of CFC compounds has dramatically decreased following the Montreal Protocol. However, CFCs already in the air will take many decades to break down. As existing CFC levels gradually decline, ozone in the upper atmosphere will rebound globally, and ozone holes will shrink.

As a result of the international agreement, the ozone hole in Antarctica is slowly recovering. Due to its widespread adoption and implementation, it has been hailed as an example of successful international co-operation. Former UN Secretary-General Kofi Annan stated that "perhaps the single most successful international agreement to date has been the Montreal Protocol".

Liftoff! At 04:11:45.459 UTC on November 25, 2025, the Long March 2F Y22 rocket launched the replacement Shenzhou-22 crew spacecraft from the Jiuquan Satellite Launch Center (JSLC) in northwestern China. This marks a historic first—the spacecraft is launching uncrewed to meet astronauts in orbit at the start of their long duration mission. In place of a crew, Shenzhou-22 is carrying essential resupplies to the China space station. China was able to replace another crewed spacecraft in just sixteen days.

Tiny cracks were found in the viewport window of the Shenzhou-20 crewed spacecraft's return capsule, most probably caused by an external impact from space debris, according to the China Manned Space Agency (CMSA). This required its rapid replacement for the crew's safety.

Shenzhou-22 Replacement Crew Spacecraft: Arrival & Docking | China Space Station

The Shenzhou-22 crew spacecraft successfully docked with the China Space Station on November 25, merely more than three hours of space flight following the liftoff, according to the China Manned Space Agency (CMSA).

The spacecraft, atop the Long March-2F Y22 carrier rocket, blasted off at 12:11 Beijing Time (0411 GMT) from the Jiuquan Satellite Launch Center in northwest China.

About ten minutes after the launch, the spacecraft separated from the rocket and entered its designated orbit. The CMSA declared the launch mission a complete success.

At 15:50 Beijing time (0750 GMT), the spacecraft successfully docked with the front port of the Tiangong space station's Tianhe core module.

The spacecraft, flying without a crew aboard, carried a cargo of space food, medical supplies, fresh fruit and vegetables, as well as devices for treating the cracked window on the Shenzhou-20 spacecraft.

It will later serve as the return vessel for the three Shenzhou-21 astronauts currently in orbit.

Tuesday's launch followed the postponed return of the Shenzhou-20 crew aboard the Shenzhou-21 spacecraft on Nov. 14. The Shenzhou-20 spacecraft was struck by space debris, delaying its return originally scheduled to take place on Nov 5, according to CMSA.

The Shenzhou-21 crew members are in good condition, and are fulfilling their tasks as planed, the CMSA said, adding that the damaged Shenzhou-20 spacecraft will remain in orbit to continue relevant experiments.

Zhou Jianping, chief designer of China's crewed space program, explained the significance of the launch, which is the first emergency launch mission under the program.

"The success of this mission fully demonstrated the strengths of China's new system for mobilizing resources nationwide, comprehensively interpreted the principle of prioritizing life and safety above anything else in China's crewed space program, comprehensively verified the scientific, reliable and safe nature of the 'one launch, one standby, rolling backup' strategy for China's space station missions, rigorously tested all personnel's rapid response and emergency handling capabilities in real-world scenarios, and vividly exemplified the spirit of the crewed space program—one characterized by exceptional capabilities to overcome hardships, work with a fighting morale, solve technical bottlenecks, and remain dedicated," Zhou said.
