New analysis of Hayabusa2 data of the asteroid Ryugu reveals much of the surface reflects and scatters light in ways that are consistent with studies of carbonaceous chondrite meteorites in the lab.

Swarms of small satellites could communicate amongst themselves to collect data on important weather patterns at different times of the day or year, and from multiple angles. Such swarms, using machine learning algorithms, could revolutionize scientists' understanding of weather and climate changes.

Engineer Sabrina Thompson is working on software to enable small spacecraft, or SmallSats, to communicate with each other, identify high-value observation targets, and coordinate attitude and timing to get different views of the same target.

"We already know that Saharan dust blowing over to the Amazon rainforests affects cloud formation over the Atlantic Ocean during certain times of the year," said Thompson, who works at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
