- 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

A material way to make Mars habitable
on July 15, 2019 at 3:42 pm
New research suggest that regions of the Martian surface could be made habitable with a material -- silica aerogel -- that mimics Earth's atmospheric greenhouse effect. Through modeling and experiments, the researchers show that a 2- to 3-centimeter-thick shield of silica aerogel could transmit enough visible light for photosynthesis, block hazardous ultraviolet radiation, and raise temperatures underneath permanently above the melting point of water, all without the need for any internal heat […]
Methane vanishing on Mars
on July 2, 2019 at 7:28 pm
Wind-driven erosion of minerals on Mars may be the reason why methane disappears so rapidly on the red planet. Saltation causes electrical charges, that can oxidize minerals and ionize gases like methane, making the ionized methane bond to the minerals. That is the explanation proposed by an interdisciplinary research group, based on laboratory experiments in a Mars-like environment. […]

Silica aerogel could make Mars habitable
on July 15, 2019 at 3:00 pm
People have long dreamed of re-shaping the Martian climate to make it livable for humans. Carl Sagan was the first outside of the realm of science fiction to propose terraforming. In a 1971 paper, Sagan suggested that vaporizing the northern polar ice caps would "yield ~10 s g cm-2 of atmosphere over the planet, higher global temperatures through the greenhouse effect, and a greatly increased likelihood of liquid water."

Moon dust is not to be sneezed at
on July 15, 2019 at 2:05 pm
When the astronauts of the Apollo 11 mission returned to Earth, they had almost 22 kilograms of rock from the surface of the moon in their baggage. Josef Zähringer from the Max Planck Institute for Nuclear Physics in Heidelberg was one of the first researchers allowed to analyze the material in the US. Two months later, Heinrich Wänke's team at the Max Planck Institute for Chemistry in Mainz also received a grain. […]
