Solving some of the world’s most pressing challenges through space-based research.
Where? In space.
Low Earth orbit(Abbreviation: LEO) The orbit around the Earth that extends up to an altitude of 2,000 km (1,200 miles) from Earth’s surface. The International Space Station’s orbit is in LEO, at an altitude of approximately 250 miles. (LEO), approximately 250 miles above the Earth.






In this issue’s cover story, learn about microbes that hitchhike with astronauts, inhabit the space station, and adapt to the unique conditions there. Other features highlight how wave patterns in vibrating fluids could improve heat removal systems and how researchers are propelling bubbles using light to precisely steer fluids—both of which are critically important for future space missions.

National Lab research announcements (NLRAs) seek proposals that advance R&D in key areas with demonstrated potential to develop into sustainable markets and benefit humanity.
