It Happened in Space – Mars PropM Rovers

Long before the Sky Crane lowered Curiosity into Gale Crater, before the twin MER rovers Spirit and Opportunity bounced across the Martian surface, even before Sojourner was a glimmer in its designers’ eyes the Soviet Union launched the twin Prop-M rovers. Though neither rover made it to the surface, the technology stands as a brilliant example of the Soviet ingenuity that gave the nation an early lead in space. I tell the Prop-Ms’ story, in brief, in my first video for Scientific American.

Incidentally, I’m very excited to announce that I’m doing a monthly video series – “It Happened in Space” – for Scientific American!

Vintage Space Favourites of 2012

The past twelve months have been very good ones. I’ve met and worked with some incredible people, ventured into the (often awkward) world of podcasts and webcasts, and have read and written more than I ever did in grad school. Of the hundreds of articles I’ve written, a few stand out as favourites. And so, in no particular order, here are my top picks of 2012. These aren’t the big news items or the articles that got the most traffic. These are the ones that were fun to research and write, and the ones that taught me something new. [Read more…]

NASA’s Plan for Mars Makes the Old New Again

Yesterday, NASA announced a bold new plan of exploration for the coming decade on Mars. It’s exciting. I love plans that include a methodical exploration of other worlds that will help answer the bigger questions out there, like why Mars developed into such a different world than the other inner bodies. But looking a little closer at what few details the agency’s released, it looks less like a concrete plan with a goal and more of a bid to capitalize on Curiosity’s unexpected fame. Which isn’t a bad thing. It’s just sort of an odd thing. [Read more…]

The Cost of Curiosity

Taken on Sol 32, this is the frist time Curiosity used its Mars Hand Lens Imager (MAHLI) camera on its arm to take this portrait of the top of its Remote Sensing Mast showing the Mastcam and Chemcam cameras. It’s as close to a headshot as Curiosity can take. Credit: NASA/JPL

The other day I was in a coffee shop, quietly writing and sharing a table with a woman also on a laptop. She caught me staring blankly out the window and asked what I was working on; apparently I looked troubled. I told her I was working on a new angle for my sixth or so Mars article that week. She seemed interested so I told her about Curiosity, the heritage technology that’s helped NASA make multiple successful Mars landings, and how the Sky Crane will open up a new future of exploration.

The idea that reusing technology saves money in spaceflight and that developing new technology now may cut costs on future missions caught her attention. She urged me to play up that angle because the amount of money NASA spends on these missions is stupid.  “Curiosity,” she said, “cost half the nation’s defense budget.” That’s when I noticed her cross necklace and asked what kind of writer she is; turns out she’s a Christian motivational writer. That’s when I wished I had the figures on hand to illustrate just how little we spend on space exploration. But I didn’t so I quietly got back to work. But I did decided that I ought to write a blog post putting Curiosity into perspective so that the next time someone tells me NASA wastes money I can tell them how wrong they are.  [Read more…]
