Strange 'eggshell planets' are among the rich variety of exoplanets possible, according to a study from Washington University in St. Louis. These rocky worlds have an ultra-thin outer brittle layer and little to no topography. Such worlds are unlikely to have plate tectonics, raising questions as to their habitability.
Only a small subset of extrasolar planets are likely eggshell planets. Ball Aerospace delivers NASA X-Ray Observatory to KSC for December launch

NASA's Imaging X-Ray Polarimetry Explorer (IXPE), built by Ball Aerospace, safely arrived Friday at Cape Canaveral in Fla. A collaboration between Ball, NASA, and the Italian Space Agency (ASI), IXPE is an astrophysics observatory set to launch from NASA's Kennedy Space Center in December.
Once on orbit, IXPE will measure the polarization of cosmic X-rays to improve our understanding of th Eagles collaborate in unique high-altitude simulation training

The first time senior Olivia Siu experienced hypoxia - a condition caused by lack of oxygen, sometimes suffered by pilots - she thought she was functioning fairly well. She was in the High-Altitude Lab (HAL) at Embry-Riddle Aeronautical University, focusing on folding a paper boat.
Despite her low oxygen intake, her dexterity was perfect, and each crease of her creation was exact. There wa LEOcloud to offer space edge cloud services on Orbital Assembly Space Stations

Satellites observe the Earth using a range of wavelengths on the electromagnetic spectrum. Different wavelengths allow us to probe different aspects of Earth’s land, atmosphere and ocean. By sampling the electromagnetic spectrum at multiple wavelengths, we can build a more complete picture of Earth’s complex climate system.
SpaceX crew launch marks 600 space travelers in 60 years

A SpaceX rocket carried four astronauts into orbit Wednesday night, including the 600th person to reach space in 60 years.
The repeatedly delayed flight occurred just two days after SpaceX brought four other astronauts home from the International Space Station. They should have been up there to welcome the newcomers, but NASA and SpaceX decided to switch the order based on Monday's ideal recovery weather in the Gulf of Mexico and pulled it off.
"It was a great ride, better than we imagined," mission commander Raja Chari said shortly after the spacecraft reached orbit.

SpaceX aims for night crew launch; ailing astronaut now OK

SpaceX counted down Wednesday toward a nighttime launch of four astronauts who have been grounded for nearly two weeks by weather and medical delays.
The Falcon rocket was poised to blast off from NASA's Kennedy Space Center a few hours after sunset. That would put the one German and three U.S. astronauts at the International Space Station by Thursday night to begin a six-month stay.
New space telescope to peer back at the universe's first galaxies

On Dec. 18, NASA is set to launch its next flagship mission into space. The spacecraft, called the James Webb Space Telescope, brings a lot of risks: Its roughly 270-square-foot mirror, which will collect light streaming in from the far reaches of space, will launch folded up inside a rocket, then unfurl far from Earth.
Astronomers are betting that the challenges will be worth it. Many have dubbed James Webb a successor to the Hubble Space Telescope—an instrument that was launched in 1990 and has delivered startling images of the cosmos, including The Pillars of Creation in the Eagle Nebula. Among other goals, James Webb will search the atmospheres of alien planets for what scientists call "biosignatures," or gases that could, theoretically, indicate the presence of life on the surface.
