Opportunity’s Selfie. It might not look too sharp, but the camera is actually a 14 year old microscope. On Mars. Image credit: NASA\/JPL-Caltech\/Doug Ellison<\/p><\/div>\n

Ever taken a selfie on your birthday? Well, that’s just what the Mars Rover Opportunity<\/a> did to celebrate its 5000th “sol” (martian day) on Mars. This doesn’t sound like much, but 5000 sols is about 14 years – not bad for a rover that was only expected to last about 3 months! The selfie<\/a> – the first one Opportunity has ever taken – was thought up and coordinated by Doug Ellison<\/a>, who has been involved with Opportunity (initially as an amateur, now at NASA JPL) since it landed way back in January 2004. Who better to speak to to find out what this plucky little rover has been up to for the last 5000 sols?<\/p>\n

There’s also an update from on ‘Oumuamua<\/a>, the interstellar asteroid that came whizzing through the Solar System in late 2017. Dr Wes Fraser<\/a>, from Queen’s University Belfast, explains what we know, what we don’t know, and what we’ll probably never find out about our fleeting visitor. Oh, and why it’s called the Space Cucumber…<\/p>\n
