Simple organic compounds detected by Curiosity on Mars

Too early to tell if findings are evidence of biological activity, scientists say

NASA’s Mars Science Laboratory (MSL) rover, Curiosity, has detected evidence of simple, chlorinated organic compounds in soil sampled recently from the red planet, project scientists announced Monday from the annual meeting of the American Geophysical Union in San Francisco. The scientists characterized the finding as very exciting, but they stressed that the results do not provide “definitive" evidence of past or present life on Mars.

Bare Earth Elements: Let the real Curiosity begin

This has been a year of scientific milestones. In just the last few months, we have witnessed the first successful launch of a privately built spacecraft — SpaceX’s Dragon capsule — which docked with the International Space Station in May, as well as the announcement in July that the Higgs Boson, the lynchpin particle in the Standard Model of physics, had at last been confidently detected. And by now, you have surely heard that Curiosity — the latest model in NASA’s lineage of robotic Mars-exploring rovers — has successfully landed on the red planet. In case you hadn’t, here is your official notice:

CURIOSITY HAS LANDED ON MARS!

Hazardous Living: Watching Curiosity land safely was exhilarating

Sometimes humanity accomplishes something absolutely awesome. Tonight was one of those nights. We put another rover on Mars — by far the most advanced rover yet. Curiosity is now out exploring Gale Crater and much is expected of her.

Blogging on EARTH: Curious to watch Curiosity land on Mars?

Sunday night will bring excitement to households around the world, not only because of the Olympics (and the GEOlympics), but also because the Mars Science Laboratory, also known as the Curiosity rover, will touch down on the Red Planet.

Bids in space: When should we outsource government science?

Government research and development has its limits: Time, money and bureaucracy can all hamper the timely progress of research. As a result, many federal agencies are looking to private companies to help drive new innovation and keep costs down — but it’s never that simple. Two current hot-button topics — returning humans to space and geoengineering — highlight a range of issues related to how private and public investment in science can coexist. This month, we focus on NASA.

A Martian icecap, now in 3-D

Move over, James Cameron. Researchers have created the first 3-D subsurface pictures of Mars’ northern icecap — and they’re using these images to solve a 40-year-old Martian puzzle.

The puzzle centered around Chasma Boreale, an ice canyon in the northern icecap that is comparable in size to the Grand Canyon, and the spiral troughs that extend in a pinwheel-fashion from the icecap’s center. How each of these features formed has long mystified researchers.

Shell tectonics may explain Mars mysteries

Mars may be mythologically known as the Red Planet, but its topography can be as captivating as its celestial glow. Several striking features stand out with only a glance at a topographic map of Mars: the odd distribution of land on its surface and the equatorial string of giant volcanoes known as the Tharsis Rise. Since Mars has no plate tectonics, how these unique features formed has been a longstanding mystery.

Phoenix takes a bow

Blogging on EARTH

One of the NASA’s most successful and widely publicized missions has ended.

On Monday, NASA scientists declared that the Phoenix Lander, a solar-powered, stationary robot laboratory designed to explore the habitability of the Red Planet, had stopped communications with Earth.
