Often eclipsed by Apollo 11, the final manned moonshot left far more than bootprints in the dust. In these troubling times, it also left us with a lasting message of hope.
Enormous odd feature presents puzzle for scientists.
Letters from would-be girl astronauts in the 1960s tell part of the complicated story of sexism – in both NASA and the US at large – at the dawn of the space age.
NASA’s Juno spacecraft has faced a series of challenges during its first 150 days.
Asgardia is calling for unrestricted research but history has given us many examples where this has resulted in unacceptable consequences.
Technology had enabled humans to explore the deep sea, the Earth’s poles, and outer space. But we shouldn’t forget historical lessons about frontiers in the process of traversing them.
Musk’s know-how cannot be dismissed but there are significant challenges standing between him and his dream of colonising Mars.
A moment of sadness with tears shed … then it was on with the work.
It has been an epic journey, much more than 12 years in the making, but Rosetta is just about to go out in a blaze of glory. The final commands were uploaded to the spacecraft mid-morning on September…
We don’t know where Tiangong-1 will land but the risk of someone being hit is about 1 in 3,200.
Scientists are hoping to collect 100g of material from asteroid Bennu.
Future factories in space could be used to launch large structural sections to build space stations.
We could be exploring the oceans of Jupiter’s and Saturn’s icy moons in a couple of decades. Here’s what we need to work out.
What viewing on the International Space Station tells us about life among the stars.
Measuring time is a crucial part of navigation – particularly in space, where exacting precision is called for. The DSAC is poised to make a change that will aid future deep space missions.
Just about anyone can get a tiny, cheap satellite into orbit these days. As we consider how to deploy them responsibly, inspiration comes from an amateur community of enthusiasts.
Why carry building materials from Earth into space, when we can build structures by 3D printing using materials found out there?
From inflatable space stations to trips to asteroids and maybe even Mars, the next decade of human spaceflight will include many exciting firsts.
It’s an ambitious plan to send a micro-spaceship to our stellar neighbour but is this possible with today’s technology or even technology in the near future?
