(07 Apr) How a ’mudball’ meteorite survived space to land in the jungles of Central America
The pieces of a meteorite that fell in Costa Rica in 2019 are so unusual that scientists believe it ...

From 05 Feb: ’It was so simple’: How Antarctica’s missing meteorites were discovered using a block of ice, a freezer and a lamp - There are hundreds of thousands of meteorites hidden beneath Antarctica’s icy surface, some of which... https://www.livescience.com/planet-earth/antarctica/it-was-so-simple-how-antarcticas-missing-meteorites-were-discovered-using-a-block-of-ice-a-freezer-and-a-lamp #astronomy #meteoroids #space
@astrodad as of 2005 "Lunar space elevators are twice the length of the Earth space elevator, but because of the Moon’s much smaller mass they can be constructed of existing materials. In addition, there are few satellites in lunar orbit, no man-made #debris, and fewer #meteoroids are expected." https://www.niac.usra.edu/files/studies/final_report/1032Pearson.pdf
#NASA 📆 April 2020 #Micrometeoroids and #SpaceDebris will strike an #orbiting Station throughout its lifetime, as is evident on the #ISS, where several #solar arrays show #damage caused by micrometeoroids. The #hope is that the #meteoroids will not hit any #critical areas and cause #emergency #evacuation of the structure. Damage from meteoroids may include damage to #habitation 💤 modules.
#Welding is one of the best ways to create hermetic seals. The ability to #weld these structures without waiting for new equipment may limit the #risks to #astronauts in the event of damage.This ability for rapid #repair may also become more significant as orbiting Stations such as #Gateway move further from #Earth and the associated #cost of shipping parts increases. It is important to #develop these technologies now.
#NASA has recently funded work on #development of #spacewelding 🎇 capabilities https://ntrs.nasa.gov/api/citations/20200002259/downloads/20200002259.pdf
