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.
The idea that there’s a moral imperative for humans to expand beyond Earth is echoed by influential proponents of space exploration.
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.
The health of astronauts will be one of the main challenges for Musk.
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.
Artist’s impression of Rosetta’s descent.
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…
Workers wave flags as the rocket carrying the Shenzhou-9 spacecraft being moved to the launch pad.
We don't know where Tiangong-1 will land but the risk of someone being hit is about 1 in 3,200.

Artist’s impression of a cryobot and submarine in the ice on Jupiter’s Europa.
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.
Right, time for a little zero gravity and chill…
What viewing on the International Space Station tells us about life among the stars.
DSAC is prepping for a yearlong experiment to characterize and test its suitability for use in future deep space exploration.
Jet Propulsion Laboratory
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.
CubeSats upon release from the International Space Station.
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.
