- 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

- Carbon dioxide reactor makes 'Martian fuel'on September 23, 2021 at 5:26 pm
Engineers are developing new ways to convert greenhouse gases to fuel to address climate change and get astronauts home from Mars.
- Mars habitability limited by its small size,...on September 20, 2021 at 7:19 pm
Researchers measured the potassium isotope compositions of Martian meteorites in order to estimate the presence, distribution, and abundance of volatile elements and compounds, including water, on Mars, finding that Mars has lost more potassium than Earth but retained more potassium than the moon or the asteroid 4-Vesta; the results suggest that rocky planets with larger mass retain more volatile elements during planetary formation and that Mars and Mars-sized exoplanets fall below a size […]
- Affordable housing in outer space: Scientists...on September 13, 2021 at 5:57 pm
Transporting a single brick to Mars can cost more than a million British pounds -- making the future construction of a Martian colony seem prohibitively expensive. Scientists have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.
- Will it be safe for humans to fly to Mars?on August 26, 2021 at 3:17 pm
A human space mission would be viable if it doesn't exceed four years, an international research team concludes in new research.

- Scientist shepherds Perseverance rover through...on September 16, 2021 at 8:39 pm
The evening of Aug. 1 felt a lot like a birthday to NASA planetary scientist Justin Simon. On that night, Simon attended a virtual watch party for researchers preparing to use NASA's Mars 2020 Perseverance rover to conduct the first detailed study of a candidate rock target for drilling and collecting a sample. Ready to unwrap presents, Simon and his fellow researchers anxiously refreshed their inboxes to see the first downlinked and up-close images of the rock—that could help them better […]

It's the next best thing to being on Mars: Two online interactive experiences let you check out Jezero Crater—the landing site and exploration locale for NASA's Perseverance rover—without leaving our planet.
- European facility prepares for haul of samples...on September 16, 2021 at 4:59 pm
The Institute of Planetary Research at DLR (German Aerospace Center) is starting construction of a new Sample Analysis Laboratory (SAL) dedicated to the study of rock and dust samples from planetary bodies such as asteroids and the Moon. The first phase will be operational by the end of 2022, on time to welcome samples collected by the Hayabusa2 mission, and fully ready by 2023. A status report will be presented today at the Europlanet Science Congress (EPSC) 2021.
- Is Venus volcanically active? New approach could...on September 16, 2021 at 2:50 pm
Out of all planets in the solar system, Venus has the most volcanoes. Much of the planet is covered in volcanic deposits that are less than 300 million years old, and volcanic activity has played a pivotal role in its history. Although the precise timeline of Venus's volcanic past is still under debate and some data suggest that the planet may still have active volcanoes, the evidence remains inconclusive.
