- 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

- Fluvial mapping of Marson December 22, 2020 at 7:15 pm
It took fifteen years of imaging and nearly three years of stitching the pieces together to create the largest image ever made, the 8-trillion-pixel mosaic of Mars' surface. Now, the first study to utilize the image in its entirety provides unprecedented insight into the ancient river systems that once covered the expansive plains in the planet's southern hemisphere.
- Powerful electrical events quickly alter surface...on December 15, 2020 at 3:43 pm
On Earth, dust particles are viewed mainly in terms of their physical effects, like erosion. But, in exotic locales from Mars to Venus to Jupiter's icy moon Europa, electrical effects can affect the chemical composition of a planetary body's surface and atmosphere in a relatively short time, according to new research.

Scientists created planetwide maps of where water might be found on Mars. It is probably scarcer than previously thought, they concluded.
- Best region for life on Mars was far below surfaceon December 3, 2020 at 12:25 am
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a new study concludes. The study may help resolve what's known as the faint young sun paradox - a lingering key question in Mars science.

There is no weather in space - but there is weathering: Celestial bodies are bombarded by high energy particles. On the Mars moon Phobos, the situation is complicated: It is hit by particles from the sun, but it is partly shielded by Mars. New experiments explain what is going on, in 2024 a space mission will reach Phobos and check the results.

Since the 1960s and '70s, scientists have come to view Mars as something of a "dead planet." As the first close-up images from orbit and the surface came in, previous speculation about canals, water and a Martian civilization were dispelled. Subsequent studies also revealed that the geological activity that created features like the Tharsis Mons region (especially Olympus Mons) and Valles Marineris had ceased long ago.

Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object—more than 10 trillion times stronger than a refrigerator magnet—and spin on their axes every few seconds.

Earth gets blasted by mild short gamma-ray bursts (GRBs) most days. But sometimes, a giant flare like GRB 200415A arrives at our galaxy, sweeping along energy that dwarfs our sun. In fact, the most powerful explosions in the universe are gamma-ray bursts.
