Elon Musk presented an update on progress SpaceX is making with plans for missions to Mars at the International Astronautical Congress (IAC) in Adelaide, Australia on Sep 29, 2017, giving insight on the company’s ambitious vision to build a foundation and infrastructure […]

Lockheed Unveils Plans for Orbiting Mars Base Camp and Lander Within 10 Years

Mars Base Camp is Lockheed Martin’s vision for sending humans to Mars in about a decade. The Mars surface lander called the Mars Accent Descent Vehicle (MADV) is a single-stage system that uses Orion systems as the command deck. It could allow astronauts to explore the surface for two weeks at a time before […]

“Range Safety Command Destruct System has been armed…fuel valves are now being opened…”

It was Friday, 25 September 1992—a quarter-century ago—as NASA counted down the final moments on Earth of its first voyage to the Red […]

Twenty years ago, this week, NASA’s Mars Global Surveyor settled into orbit around the Red Planet, to begin what NASA described as “a sustained program of exploration” of our third-closest celestial neighbour after the […]

Hotsprings in Gale Crater? Curiosity Rover Finds New Evidence for Ancient Hydrothermal Activity

For the silver foxes among us, we may remember where we were when JFK died or when Challenger breathed her last in the skies above the Kennedy Space Center (KSC). But for NASA’s Curiosity rover—which alighted on Mars, […]

'Sprained Ankle': Opportunity Rover Sends Back New Panorama from Above Ancient Gully

NASA’s Opportunity rover has been […]

'No More Wheelies' Software Gives Curiosity Better Traction on Different Rocks

View of two of the raised treads (grousers) on the left middle wheel of the Curiosity rover which recently broke, including the one seen partially detached at the top of the wheel. NASA has now developed a new algorithm that adjusts the rover’s wheels speed depending on the rocks it’s climbing, to minimize wear […]

New Findings from Curiosity Hint Ancient Mars Lake 'Favorable for Different Microbial Life'
