NASA has no plans to exchange lunar samples with China
Wednesday, 01 September 2021 00:31
NASA currently has no plans to trade any of its Apollo-era lunar samples with those returned by China’s Chang’e-5 mission, although then agency’s chief scientist held out hope for such an exchange in the future.
Liquid nitrogen shortage delays Landsat 9 launch

A one-week delay in the launch of the next Landsat satellite on an Atlas 5 is the result of a ripple effect in the supply chain caused by increased demand for liquid oxygen to treat COVID-19 patients.
'X-ray magnifying glass' enhances view of distant black holes
Tuesday, 31 August 2021 18:19
By taking advantage of a natural lens in space, astronomers have captured an unprecedented look at X-rays from a black hole system in the early universe.
This magnifying glass was used to sharpen X-ray images for the first time using NASA's Chandra X-ray Observatory. It captured details about black holes that would normally be too distant to study using existing X-ray telescopes.
Astronomers applied a phenomenon known as "gravitational lensing" that occurs when the path taken by light from distant objects is bent by a large concentration of mass, such as a galaxy, that lies along the line of sight. This lensing can magnify and amplify the light by large amounts and create duplicate images of the same object. The configuration of these duplicate images can be used to decipher the complexity of the object and sharpen images.
The gravitationally-lensed system in the new study is called MG B2016+112.

Geologists propose theory about a famous asteroid
Tuesday, 31 August 2021 15:23
The asteroid Vesta is the second largest asteroid in our Solar System. With a diameter of about 330 miles, it orbits the sun between the planets Mars and Jupiter.
Asteroids have long played a part in building popular fascination with space. "Marooned off Vesta" was the first story published by American writer Isaac Asimov, the third story he wrote, appearing in the March 1939 issue of the science fiction magazine Amazing Stories.
"When we think of asteroid belts, we probably picture Han Solo maneuvering the millennium falcon through a dense set of irregularly shaped gray rocks in space," Christian Klimczak, associate professor in the Franklin College of Arts and Sciences department of geology. "While most rocks are indeed irregularly shaped and gray, they are far apart and NASA's Dawn spacecraft did not have to maneuver around any other asteroids to reach and explore Vesta."
Dawn was the space probe launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt, Vesta and Ceres.
Vesta, like Earth, is composed of rock in its crust and mantle, and it has an iron core.
Spacecraft deorbiting device ready for upcoming test launch
Tuesday, 31 August 2021 15:19
A drag sail that a team at Purdue University developed to pull launch vehicles in space back to Earth is scheduled to undergo a test launch on Thursday (Sept. 2).
The mission, set to take off from Vandenberg Space Force Base in California, will evaluate how well the prototype helps its vehicle deorbit from space after mission completion. A livestream of the launch will be available through Everyday Astronaut.
Faster deorbiting times may prevent spacecraft and launch vehicles from turning into hazardous space debris as they wait to deorbit naturally, a process that could take days, months or years without assistance. Abandoned, lost or post-mission space vehicles are part of the more than nine thousand tons of space debris currently traveling through Earth's lower orbit at dangerous speeds.
