Schirra’s Stellar Navigation

Simulators have always been an integral part of spaceflight. In the case of the all important reentry and landing phase, simulators were like analogue versions Google Earth: reproductions of landscapes from specific altitudes taught astronauts to look for when lining up their spacecraft for reentry. But as Wally Schirra learned on his Sigma 7 flight, landing simulators can’t prepare you for everything.  [Read more…]

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!

The U-2 With Fictitious NASA Markings

Researching the U-2 spy plane the other day, I came across this stunning picture of the aircraft in silhouette. For the first time I noticed a yellow NASA stripe and an ID number – 55741 – on the tail, the same markings the agency put on the X-15’s tail when it assumed control of that program in 1958. Idly interested in NASA’s history with the U-2, I searched for records of the aircraft by its ID number. Turns out, these NASA markings were put on the aircraft entirely for show.   [Read more…]

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…]
