Let's review what we know about NASA's Martian secret heard round the solar system last week:

An NPR reporter happened to be recording in the office of the lead scientist for the Curiosity rover as some data from the rover's on-board chemistry lab was coming in. When pressed by the reporter to interpret the data, NASA's John Grotzinger declined, commenting simply that the "data is going to be one for the history books."… Read more

It seems NASA and the Curiosity rover have found something exciting and nerd-tastic on Mars, but the space agency's scientists are holding back for now, despite how painful it appears to be for them.

NPR science correspondent Joe Palca happened to be in the room recently when John Grotzinger, lead scientist for the Curiosity mission at NASA, started receiving data on his computer from the rover's on-board chemistry lab, also known as SAM (sample analysis at Mars). SAM and NASA scientists on Earth have been busy analyzing a sample of Martian soil of late, and apparently the dirt from the Red Planet has a secret to tell.

"This data is going to be one for the history books, it's looking really good," Grotzinger said in the story that aired yesterday.

And that's about all he said.… Read more

"Now, this is the plan. Get your ass to Mars."

We all remember Schwarzenegger motivating himself to go to the Red Planet in "Total Recall" (anyone bother watching the remake?) and sure we'd like to go too. Now NASA's Curiosity Mars rover has determined that radiation levels on the planet's surface are safe for human explorers.

"The astronauts can live in this environment," Don Hassler, principal investigator on Curiosity's Radiation Assessment Detector instrument (RAD), told a news conference.

"Basically, we're finding that the Mars atmosphere is acting as a shield for the radiation on the surface and as the atmosphere gets thicker, that provides more of a shield and therefore we see a dip in our radiation dose," Hassler said.

The findings mark the first time that cosmic rays have been measured on the surface of another planet, and come 100 years after Victor Hess discovered cosmic rays on Earth by using a hot-air balloon.… Read more

Buffeted by ethereal whirlwinds and twisters, the Curiosity Mars rover is wrapping up initial soil analysis operations at a sandy drift where it's been parked for more than a month, project scientists said today. The rover is now being prepared to move on in search of suitable targets for a compact rock drill, the final major sample acquisition system to be tested.

Ashwin Vasavada, the deputy project scientist for the Mars Science Laboratory rover at the Jet Propulsion Laboratory in Pasadena, Calif., told reporters that Curiosity's robot arm had completed five scoops of martian soil, using the sandy … Read more

3D printing has captured the imaginations of just about anyone who knows what it is -- even NASA, apparently.

The space agency is using a similar technology to create precise metal parts for its next heavy-lift rocket, which it hopes will eventually help take humans to Mars.

The method is called selective laser melting, or SLM, but it's not quite the same as printing up a sweet "Star Wars" chess set out of extruded plastic. It's more of a cross between 3D printing and some high-end, defense-grade awesome tech.… Read more

It's as if you've just strolled up to Curiosity on the surface of Mars and surprised the rover as -- convinced that everyone at Mission Control is on a coffee break -- it's decided to ditch the scientific research for a bit and build a martian sand castle instead.

One of the latest Curiosity images posted by NASA is a stunning self-portrait made up of 55 high-rez images taken by the rover's Mars Hand Lens Imager. The base of Mount Sharp serves as a dramatic backdrop, swooping up toward the right, and in front of the rover, you can see four hand-size holes in the ground where Curiosity had just started building its sand castle gathered scoops of martian dirt for analysis. The scoop site is poetically named "Rocknest."… Read more

Felix Baumgartner hasn't stopped leaping.

The man who chose to risk his life on behalf of mankind and a caffeinated drink, wants you to know that sending little machines to Mars is a pointless exercise.

Yes, you might have thought that the famed sky-leaper would be in favor of any sort of spatial exploration.

But, no. In an interview with the Telegraph he made it clear that the Mars money could be spent more wisely.… Read more

Perhaps the Red Planet isn't quite so red as we thought. NASA's Curiosity rover has been digging up some unusual bits in the soil of Mars. A couple weeks ago, the rover found a strange bright object which later turned out to be a part of the rover itself. Now we have a new mystery object to contend with.

Curiosity took a few scoops of Martian soil from a patch called "Rocknest." That activity uncovered a bright particle in the pit it created. Unlike the earlier object, NASA has confirmed the new piece is of Martian origin. There are others like it scattered around.… Read more

It looks like the latest Mars mystery has been solved. Dashing the hopes of the many people who thought the Curiosity rover had located their lost keys or earrings, NASA has decided that a strange, bright object found on the surface is actually a piece of plastic.

According to a NASA status report, "The rover team's assessment is that the bright object is something from the rover, not Martian material. It appears to be a shred of plastic material, likely benign, but it has not been definitively identified."… Read more
