Catalog of known near-Earth asteroids tops 15,000
more »
The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. This milestone marks a 50 percent increase in the number of known NEAs since 2013, when discoveries reached 10,000 in August of that year. Surveys funded by NASA's Near Earth Object (NEO) Observations Program (NEOs include both asteroids and comets) account for more than 95 percent of discoveries so far. The 15,000th near-Earth asteroid is designated 2016 TB57. 2016 TB57 is a rather small asteroid -- about 50 to 115 feet (16 to 36 meters) in size -- that will come closest to Earth on Oct. 31 at just beyond five times the distance of the moon. It will safely pass Earth.

Serendipity, expertise, foresight and the equivalent of an Earth observation data archaeological dig have led to recovery of almost-40-year-old satellite imagery - thought lost forever - which will significantly add to understanding of our planet’s climate.

What happens to a pathogenic fungus grown in space?
more »
A new study provides evidence that Aspergillus fumigatus, a significant opportunistic fungal threat to human health, grows and behaves similarly on the International Space Station compared with Earth. The study provides important information that can help with space exploration. As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats.
