- Visioning Spacesteads (8/8/2018) - Space, the final frontier… Humans have been imagining what it would be like to setup homesteads and live in space for about as long as they’ve been imagining how to get there, but the process didn’t really take off until after we actually got there. Back in the 1970’s NASA dedicated some resources to the … Continue reading Visioning Spacesteads
- Octopuses from Space! (5/20/2018) - Did you hear the one about the octopuses from space? It sounds like the title of a cheesy sci-fi movie, doesn’t it? But it isn’t, this time, or at least, yet. Instead, it’s actually an oddball theory that’s been put forth in a recently published “scientific” article that’s getting quite a lot of buzz in … Continue reading Octopuses from Space!

Mars InSight lander reaches red planet (Alexandra Witze, Nature) NASA’s InSight Mission Triumphantly Touches Down on Mars (Ian O’Neill, Scientific American) InSight has landed with Updates (Emily Lakdawalla, Planetary Society) Landing Replay (SciNews) Original Post If you hear a phrase like “six and a half minutes of … Continue reading Mars is hard!
- Mars 3D (11/16/2016) - Mars is getting even more attention than usual this week, and that is “mostly” because National Geographic began airing their special six part Mars series on Monday nights (9/8c). Here’s a trailer and links about it… Virtual Trip to Mars Offers Ultimate Preview to Crewed Mission (Nadia Drake, National Geographic) Inside Nat Geo’s Incredible Documentary … Continue reading Mars 3D
- Get Lost in Space! (9/14/2018) - Way back in August, in anticipation of the start of a new school year, I set out to update the pages on this site related to space. Those pages tend to be popular among the teachers and students who use Cosma, and I happen to enjoy updating them, too. It sounded like a short, fun … Continue reading Get Lost in Space!
- ExoMars (10/19/2016) - Oct. 21 Update: Unfortunately, the ExoMars mission’s Schiaparelli lander did not make a successful landing due to technical difficulties, and the crash site has been found. Happily, the mother ship did successfully enter orbit. Why Schiaparelli Probe’s Mars ‘Crash Land’ Is No Failure (Mason Peck, Newsweek) Mars Reconnaissance Orbiter views Schiaparelli landing site (ESA) Here’s … Continue reading ExoMars

Mars is the fourth planet from the Sun in the Solar System. Named after the Roman god of war, Mars, it is often described as the “Red Planet” as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. — Wikipedia

It will be one of the most daunting, complicated and, potentially, scientifically rewarding missions ever undertaken to the red planet. Ministers at a recent meeting of the European Space Agency (ESA) have fully committed to plans to collect samples from the surface of Mars and return them to Earth, in a joint effort with NASA. Official approval for the NASA budget to cover this mission is anticipated early next year.

As NASA's Curiosity rover makes its way over the surface of Mars, it's sometimes accompanied by clouds drifting by in the sky above. Like Earth, the Red Planet has a water cycle, with water molecules moving between the surface and the air, traveling through the atmosphere and coming together to form clouds. The behavior of water-ice clouds on Mars plays a big role in its climate, and this computer simulation shows them forming and dispersing over the course of a Martian day.
