The Parker Solar Probe has flown nearer to the sun than any other mission. The probe is now sending back data on the behaviour of electromagnetic waves emitted from the coronal mass. Fluctuations in these waves can lead to solar flares ,which in turn can have a huge impact on earth, including the potential to knock out global communications.

The Japanese space agency’s Hayabusa mission successfully landed two robots on an asteroid 4 years away from earth. Next year the mission will return to mine rock samples from beneath the asteroids surface by shooting a ‘space cannon’ to blast samples from within the asteroid.

NASA has a similar mission planned again to collect rocks from an asteroid, their method is to use kind of ‘space hoover’ to suck up samples.
The engineering challenges of creating a spacecraft that could eventually take us all the way to Mars. Then there are the challenges of engineering the humans for that momentous journey. In space, no-one can hear you scream, which is probably a good thing if you’re going to be trapped in a metal box for two years with the same people, as you cruise through the void on your way to the red planet. So how do astronauts prepare for the physical and psychological impacts of long-term space travel? We also discover how space travel can be made greener and cleaner and test a space harpoon designed to tackle the millions of pieces of space debris floating around our planet that potentially, could impact a mission before it even leaves Earth orbit.
