Mice in space: NASA's latest experiment

Scientists are sending mighty mice to space, but rather than being gym rats, their strength was enhanced through genetic experimentation in the hopes of preventing human astronauts from experiencing muscle loss in microgravity.

Meteorite-loving microorganism

Chemolithotrophic microorganisms derive their energy from inorganic sources. Research into the physiological processes of these organisms—which are grown on meteorite—provides new insights into the potential of extraterrestrial ...

Building a Mars base with bacteria

How do you make a base on Mars? Simple: you send some bacteria to the red planet and let them mine iron. After a couple of years, you send in human settlers who use the iron to construct a base. That, in a nutshell, is the ...

Hibernating astronauts would need smaller spacecraft

If a sci-fi spaceship does not come with hyperdrive then it is usually fitted with hibernation capsules instead. In movies from 2001: A Space Odyssey to Event Horizon, Alien to Passengers, fictional astronauts get put into ...

NASA's Mars 2020 will hunt for microscopic fossils

Scientists with NASA's Mars 2020 rover have discovered what may be one of the best places to look for signs of ancient life in Jezero Crater, where the rover will land on Feb. 18, 2021.

How to control biofilms in space

Researchers from MIT will be collaborating with colleagues at the University of Colorado at Boulder on an experiment scheduled to be sent to the International Space Station (ISS) on Nov. 2. The experiment is looking for ways ...

Looking for lurkers —a new way to do SETI

The most recently discovered group of rocky bodies nearby Earth are termed co-orbital objects. These may have been an attractive location for extraterrestrial intelligence (ETI) to locate a probe to observe Earth throughout ...
