Natural environments favor 'good' bacteria

A new study has shown that restoring environments to include a wider range of species can promote "good" bacteria over "bad"—with potential benefits for human health.

New model accurately predicts harmful space weather

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt. A paper recently published ...

Van Allen Probes prepare for final descent into Earth's atmosphere

Two tough, resilient NASA spacecraft have been orbiting Earth for the past six and a half years, flying repeatedly through a hazardous zone of charged particles known as the Van Allen radiation belts. The twin Van Allen Probes ...

Exploring Mercury in a new book

Up until 2008, only one spacecraft had ever visited the planet Mercury, and it didn't linger long. NASA's Mariner 10 mission flew past the tiny world three times in the 1970s, giving humanity a helpful but limited glimpse ...

2-D material has space vehicle applications

A new study from The Australian National University (ANU) has found a number of 2-D materials can not only withstand being sent into space, but potentially thrive in the harsh conditions.

Video: Satellites and the modern economy

Satellites bring immense benefits to everyone on Earth. From monitoring our changing planet and increasingly severe natural disasters, to providing resilient telecom networks and delivering services such as precise navigation ...
