ITS: SpaceX’s bold vision for crewed exploration of the solar system
It has long been known that SpaceX’s long term goal is the colonization of Mars. Everyone from the engineers to their CEO, Elon Musk, dreams of a world away from home. In September of 2016, we got a glimpse of how SpaceX is going to get there. At last, the long rumored Interplanetary Transport System …
Why did Schiaparelli crash during landing?
Contact with the ExoMars Schiaparelli lander was lost during its attempt to make it to the surface last October. It was later discovered that the lander had crashed into the surface of the Red Planet. A large volume of data recovered from the Mars lander shows that the atmospheric entry and associated braking occurred exactly …
Skimming an alien atmosphere
After the smooth arrival of ESA’s latest Mars orbiter, mission controllers are now preparing it for the ultimate challenge: dipping into the Red Planet’s atmosphere to reach its final orbit. The ExoMars Trace Gas Orbiter is on a multiyear mission to understand the tiny amounts of methane and other gases in Mars’ atmosphere that could …
Record number of missions at the Red Planet
So, the ‘Great Galactic Ghoul’ strikes again? This tongue-in-cheek entity is invoked by NASA scientists and engineers when missions experience difficulties, especially at Mars. After a seven month journey for ESA’s first ExoMars mission, contact with its Schiaparelli Lander was lost just before its scheduled touch-down on 19th October last year, although its Trace Gas Orbiter (TGO) successfully entered into orbit around the Red Planet and is functioning well. However, rather than the work of a cosmic ‘gremlin’, the …
Methane in the membrane (Producing rocket fuel on Mars)
Vocabulary • Carbon (C): Element with a mass of 12 g/mole • Hydrogen (H): Element with a mass of 1 g/mole • In-Situ Resource Utilization (ISRU): Taking advantage of a planet’s natural resources to supplement a space mission • Low Mars Orbit (LMO): The minimum altitude above the Martian surface necessary to maintain a stable …
Stuck on Mars: Comparing Mars analog simulations to ‘The Martian’
I’ve never been stuck on Mars, or any other planets save for this one. But I have had a chance to simulate what life would be like to live on Mars during a long-duration analog simulation. Like fictional astronaut Mark Watney in Andy Weir’s “The Martian”, participants in analog simulations often find themselves having to …
