European Space Agency astronaut Alexander Gerst snapped this spectacular view of the moon, Earth’s nearest neighbour and the next target for astronauts moving beyond low-Earth orbit, from his perch aboard the International Space Station. This week, ESA hosted a workshop in the Netherlands to discuss lunar resources and their role in sustainable space exploration. Learning how to extract oxygen and water for life support, producing propellants and building habitats and other structures using available resources will be critical to making such missions affordable, space planners say. ESA is meeting with industry officials, potential partners and space experts to explore “the technological readiness, commercial viability, legal status and international context for lunar resource use.”
Decisions on the future of a joint robotic mission between NASA and the European Space Agency to demonstrate the ability to deflect an asteroid on a collision course with Earth have been put off until later this year after European governments declined to fully fund their part of the project in December.
Astronomers have used modern techniques to create a 3-D visualisation of all of the O- and B-type stars within 500 parsecs (1,630 light-years) of the Sun using data from ESA’s Hipparcos satellite. This new visualisation uncovers evidence for new structures in the distribution of these nearby hot stars, and new and surprising theories of how those stars formed.
In this image we see the young lunar crescent as seen from the International Space Station by ESA astronaut Tim Peake on 9 February 2016. At the time of the photograph the Moon was just 1.2 days old. Features on the Earth-facing side of the Moon not directly illuminated by the Sun are glowing softly due to earthshine, light reflected onto the Moon from our planet.
