- 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 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

- Martian global dust storm ended winter early in...on July 22, 2021 at 11:50 pm
A dust storm that engulfed Mars in 2018 destroyed a vortex of cold air around the planet's south pole and brought an early spring to the hemisphere. By contrast, the storm caused only minor distortions to the polar vortex in the northern hemisphere and no dramatic seasonal changes.
- Meet the Martian meteorite hunterson July 22, 2021 at 11:50 pm
A team is paving the way for future rovers to search for meteorites on Mars. The scientists are using an extensive meteorite collection to test the spectral instruments destined for the ExoMars rover Rosalind Franklin, and develop tools to identify meteorites on the surface of the red planet.

A team created a catalyst from molybdenum fertilizer that reduces >99.9% of perchlorate in water and could be used to clean soil on Mars and make oxygen for human explorers.
- Volcanoes on Mars could be active, raising...on May 10, 2021 at 11:25 pm
New observations reveal that Mars could still be volcanically active, raising the possibility for habitable conditions in the near surface of Mars in recent history. Ongoing research investigates the possibility that the most recent volcanic activity on Mars, which occurred about 50,000 years ago, might have been triggered by a nearby asteroid impact that happened around the same time.

Marine scientists often feel like they're fumbling in the dark. The global ocean covers about 71 percent of our planet and is central to life as it exists on Earth. But only about 20 percent of the seafloor has been directly mapped so far.

When NASA's Ingenuity Mars Helicopter hovered above the Red Planet April 19 on its maiden voyage, the moment was hailed as the first instance of powered, controlled flight on another planet. Figuring out how to fly on Mars, where the air is thin but gravity is about a third of that on Earth, took years of work. Along with the challenge of developing a craft that was up to the task, the mission needed software to make the unprecedented flights possible.
