- 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 new water treatment technology could also help...on June 4, 2021 at 4:25 pm
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.
- Icy clouds could have kept early Mars warm enough...on April 26, 2021 at 7:48 pm
A new study led by a planetary scientist uses a computer model of Mars to put forth a promising explanation onto how Mars once contained rivers and lakes: Mars could have had a thin layer of icy, high-altitude clouds that caused a greenhouse effect.
- Seismicity on Mars full of surprises, in first...on April 23, 2021 at 5:00 pm
The SEIS seismometer package from the Mars InSight lander has collected its first continuous Martian year of data, revealing some surprises among the more than 500 marsquakes detected so far.
- Mars has right ingredients for present-day...on April 22, 2021 at 7:04 pm
New research suggests that rocks in the Martian crust could produce the same kind of chemical energy that supports microbial life deep beneath Earth's surface.

The blob, captured on distant, fuzzy video by Navy pilots, seems to skitter just above the ocean waves at improbable speed, with no discernible means of propulsion or lift. "Oh my gosh, man," one aviator says to another as they laugh at the oddity. "What ... is it?"
- Astronomers calculate genesis of Oort cloud in...on June 3, 2021 at 11:45 am
A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar system. The astronomers will soon publish their comprehensive simulation and its consequences in the journal Astronomy & Astrophysics.
- Atmospheric metal layers appear with surprising...on June 2, 2021 at 10:47 am
Twice a day, at dusk and just before dawn, a faint layer of sodium and other metals begins sinking down through the atmosphere, about 90 miles high above the city of Boulder, Colorado. The movement was captured by one of the world's most sensitive "lidar" instruments and reported today in the AGU journal Geophysical Research Letters.
- How were the carbon contents in terrestrial and...on June 1, 2021 at 4:57 pm
Carbon degassed from planetary mantles by volcanic activity plays an important role in the planetary surface environment. However, how the carbon content in the Earth's mantle was established is still poorly understood. Here we show that the mantle of planetary embryos may have been nearly saturated with carbon by new high-pressure experiments and point out that the carbon solubility of magma is very consistent with the estimated carbon contents in terrestrial and lunar mantles.
- Dunes trapped in a crater on Mars form this...on June 1, 2021 at 11:25 am
Symmetry in nature is pleasing to look at, and even more so when that symmetry is novel. There's plenty of it to see on Earth, as biological processes have a penchant for patterns. But finding it off-world is trickier, and sometimes more striking. Which is why a picture from HiRISE of some Martian dunes is so spectacular.
