The Enduring Mystery of the Martian ‘Blueberries’ Discovered by Opportunity Rover

NASA has officially called an end to the historic Opportunity rover mission, ending a spectacular, 14-year adventure on the Red Planet. One of the rover’s most intriguing discoveries, however, came just two months after it landed, when it stumbled upon tiny objects bearing a startling resemblance to blueberries — the nature of which still divides scientists today.

The Sheer Distance Opportunity Roved Across Mars Still Has Us in Awe

As we remember the now-officially-dead Opportunity rover this week, one fact keeps sticking out to me: that machine travelled a whopping 45 kilometres across the surface of another planet. And it did so in short, nerve-wracking spurts. Spread over the course of 14 years then 45 kilometres may not sound like that much, but consider the many obstacles Oppy faced – including an agonising 38 days stuck spinning its wheels in a soft sand dune.

Scientists Remember the Mars Rover Opportunity as Hope Fades for Its Resurrection

A brutal dust storm engulfed Mars last summer. The planet-wide tempest spared the nuclear-powered Curiosity rover, but the older, solar-powered Opportunity rover shut down as the thick dust blocked light from the Sun. Opportunity has remained silent since June 10, 2018, despite NASA’s hundreds of attempts to contact it. When a windy season on Mars began in November, scientists hoped that gusts might clear debris from its solar panels, but that hope appears to have been in vain. NASA continues to send recovery commands, but sadly, it seems the Opportunity mission has finally come to an end. Read More >>

Turns Out One-Way Trips to Mars Not Exactly Great Business Plan

Remember Mars One, that company we all knew was a scam but still kind of hoped was real because of how much we liked the movie The Martian? Yeah, it went bankrupt. Read More >>

Where Are We On Colonising Other Worlds?

Since Elon Musk decided that now would be a good moment to test fire his fart-powered Mars rocket engine (no really, those things run on standard methane, which is a good thing), we thought now would also be a good moment to see exactly where we’ve got to in the quest to colonise other worlds.

New Horizons Images Show Ultima Thule May Actually Be More ‘Pancake’-Shaped

The distant (486958) 2014 MU69, nicknamed Ultima Thule, made history on New Year’s Day for becoming the farthest object ever visited by a spacecraft. As it’s situated in the Kuiper Belt about 4.1 billion miles from Earth, there’s much about MU69 that scientists are still learning. Now, new images have raised even more questions about the mysterious object. Read More >>
