SpaceX Launches Indian-origin Astronaut Raja Chari-led Crew 3 Mission
US Space agency NASA and the Elon Musk-owned private rocket company SpaceX have launched the "Crew 3" mission on November 10, 2021. The "Crew 3" mission consists of Indian-origin NASA astronaut Raja Chari as its mission commander. The other three astronauts are NASA's Tom Marshburn (pilot); and Kayla Barron (mission specialist); as well as ESA (European Space Agency) astronaut Matthias Maurer (mission specialist).
Under this mission, four astronauts have been sent to the International Space Station (ISS) for a six-month science mission until April 2022. The four-member international crew of astronauts lifted off from Launch Complex 39A at NASA's Kennedy Space Center in Florida onboard the SpaceX Crew Dragon capsule named Endurance fixed to Falcon 9 rocket.

Hubble Finds Free-Floating EGGs in Northern Coalsack Nebula
The free-floating Evaporating Gaseous Globules (frEGGs) are the recently-discovered class of star-forming nurseries.
frEGGs are compact globules of interstellar dust and gas within which low-mass stars are being born.
These very rare objects were first identified in Hubble images of the Eagle Nebula in 1995.
They have very long tails and are approximately 100 AU (astronomical units) across.

World's Thinnest X-ray Detector Created
The structural characteristics of biological specimens, such as wet proteins and living cells, can be conveniently probed in their host aqueous media using soft X-rays. Conventional X-ray detectors in this area have low spatial resolution, limited sensitivity, and require complex fabrication procedures. Many of these limitations are overcome by introducing a direct soft X-ray detector based on nanosheets of tin monosulfide (SnS).
The SnS nanosheets respond very quickly, within milliseconds.
You can scan something and get an image almost instantaneously. The sensing time dictates the time resolution.
The soft X-ray detector created by Professor Jasieniak and colleagues is less than 10 nanometers thick.
Previously, the thinnest X-ray detectors created were between 20 and 50 nanometers.
SpaceX Capsule with 4 ISS Astronauts Returns to Earth, Ending 200-day Flight
Four astronauts returned to Earth, riding home with SpaceX to end a 200-day space station mission that began last spring.
Their capsule parachuted into the Gulf of Mexico off the coast of Pensacola, Florida.
Their homecoming — coming just eight hours after leaving the International Space Station — paved the way for SpaceX's launch of their four replacements.

First Chinese Woman Walks in Space Scripts History
Wang Yaping became the first Chinese woman astronaut to walk in space as she moved out of the under-construction space station and took part in extravehicular activities for over six hours along with her male colleague Zhai Zhigang.
The two moved out of the space station core module called Tianhe and spent 6.5 hours of the spacewalk and successfully returned to the module.
This marks the first spacewalk in Chinese space history involving a woman astronaut.
NASA Picks Landing Site at the Moon's South Pole for Ice-drilling Robot
NASA has set its sights on the moon's South Pole in its quest for ice.
The space agency and the company Intuitive Machines announced Shackleton Crater landing site at the South Pole of the moon for a small lander set to launch next year. The location is called the "Shackleton connecting ridge" and NASA data hint at ice lurking below the surface.
The robotic mission includes NASA's Polar Resources Ice-Mining Experiment-1 (PRIME-1) that requires solar power and a view of Earth for communications. The ridge zone should provide both.

China Launches 3 New Remote Sensing Satellites
China successfully launched three new remote sensing satellites from the Xichang Satellite Launch Centre located in southwestern Sichuan province.
The satellites belong to the Yaogan-35 family.
They were launched by a Long March-2D carrier rocket and entered the planned orbit successfully.
This was the 396th mission for Long March series carrier rockets of China.
