Studying DNA breaks to protect future space travelers

Earth's atmosphere shields life on the ground from cosmic radiation that can damage DNA. Astronauts in space have no such protection, and that puts them at risk. An investigation on the International Space Station examines ...

CLASP-2: Investigating the magnetic solar chromosphere

Four years ago, an international team (USA, Japan and Europe) carried out an unprecedented suborbital space experiment called CLASP-1, motivated by theoretical investigations carried out at the IAC by Javier Trujillo Bueno ...

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 ...

Video: A successful mission starts with nutrition

Centuries ago, large, wooden ships explored the seven seas. But often a ship that began its voyage with a crew of hundreds could return with tens. The silent killer? Scurvy, a disease that occurs when there's a lack of Vitamin ...

Video: Building spaceships

How do you build a spaceship? It's not easy – because space is hard. It's endless vacuum, hot and cold at the same time, streaked with radiation – and you have to fly at eight kilometres per second just to get there.

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 ...

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.

Earth's atmosphere stretches out to the moon – and beyond

The gaseous layer that wraps around Earth reaches up to 630,000 kilometers away, or 50 times the diameter of our planet, according to a new study based on observations by the ESA/NASA Solar and Heliospheric Observatory, SOHO, ...

Health threat from cosmic rays

The health threat from cosmic rays is the danger posed by cosmic rays generated by the Sun and other stars to astronauts on interplanetary missions. Cosmic rays consists of high energy protons and other nuclei. They are one of the most important barriers standing in the way of plans for interplanetary travel by crewed spacecraft.
