NASA goes on an ESCAPADE – twin small, low‑cost orbiters will examine Mars’ atmosphere

The twin spacecraft Blue and Gold could open a new era in space exploration and planetary science, powered by commercial partnerships and innovations.

SETI’s ‘Noah’s Ark’ – a space historian explores how the advent of radio astronomy led to the USSR’s search for extraterrestrial life

Radio astronomy opened up the universe for scientists. They could map new elements across galaxies and also search for signals from extraterrestrial civilizations.
Many companies and space agencies want to send satellites to orbit the Moon, and crowding could become a concern. European Space Agency ©ESA

With more Moon missions on the horizon, avoiding crowding and collisions will be a growing challenge

The US doesn’t currently have much ability to monitor what’s going on in the space around the Moon. An effort by the Air Force Research Laboratory could help.

Astronauts can get motion sick while splashing back down to Earth – virtual reality headsets could help them stay sharp

Astronauts generally can’t look out the window like you might in a car – a ‘virtual window’ could instead serve that purpose.

Space exploration in the backyard, on a budget – how NASA simulates conditions in space without blasting off

A planetary scientist who has participated in analog missions describes their value for planning space exploration – and learning about extreme environments on Earth.
Flux ropes (simulated, right) are structures made up of magnetic field lines wrapping around each other like a rope, that look similar to tornadoes on Earth. NOAA, Mojtaba Akhavan-Tafti and Chip Manchester

‘Space tornadoes’ could cause geomagnetic storms – but these phenomena, spun off ejections from the Sun, aren’t easy to study

Unprecedented simulations show the formation of space tornadoes capable of causing strong geomagnetic storms around Earth, calling for earlier and more accurate warnings.
The Sun occasionally ejects large amounts of energy and particles that can smash into Earth. NASA/GSFC/SDO via WikimediaCommons

What are solar storms and the solar wind? 3 astrophysicists explain how particles coming from the Sun interact with Earth

Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.
