On February 24, 2011, the space shuttle Discovery launched for its final trip into orbit. The main objective of the STS-133 mission is to deliver and install a permanent multipurpose module (what NASA is calling a ‘floating closet’) to give occupants of the International Space Station increased storage. Discovery is also delivering Robonaut 2 to the ISS. It is the first human analogue to go in space; it will undergo a series of tests to see how well a robot can function in a zero gravity environment. (Pictured is Discovery on the launch pad the eve before launch. February 23, 2011.)
While this is Discovery’s last fight, the shuttle program as a whole has two more mission lined up: STS-134 will see Endeavour launch into orbit on April 19, and STS-135 will see Atlantis launch on June 28. Even taking into account possible delays and scrubbed launches, it’s safe to say the shuttle program will likely be finished by the end of 2011. So, what’s next?

The Gemini program is often passed over in popular accounts of NASA’s race to the Moon. Perhaps understandably so. Gemini doesn’t carry the excitement of the Mercury Program with America’s first steps into space and it lacks the climactic excitement of the Apollo program with a lunar landing. The major accomplishments of the Gemini Program are usually highlighted in the greater scheme of the space race, such as America’s first extravehicular activity (EVA) or the first docking of two spacecraft. (Pictured is Gemini 7 in orbit as seen from Gemini 6. 1965.)
On the whole, however, Gemini is often treated like NASA’s overlooked middle child of the space race, a sad fate for the program I would argue is actually the most interesting of the era. As such, this promises be the first of several posts focussing on various aspects of the Gemini program. What fascinates me the most is that Gemini exemplifies the pioneering spirit and technological “go for broke” attitude NASA embodied in the 1960s. Even the genesis of Gemini is an interesting as it forced NASA to design a program in support of an as-of-yet- undesigned lunar program. The fundamental design choices of Apollo shaped Gemini.

Like Venus, Mars has long been an object of fascination to men – the red wanderer among the heavens, historically associated with the God of war, whose retrograde motions baffled astronomers for centuries. More than any other planet, Mars has experienced oscillating periods of interest; it has dominated astronomical studies as an irregularity and a world teeming with intelligent life, and falling into disinterst as a cold world. The trend has continued in the modern era of space exploration, with rovers and orbital spacecraft returning periodically to the red planet to explore the latest point of interest. (Pictured: Mars.)
Before this modern technological era, Mars enjoyed great popularity in the Victorian era as a life-harbouring planet. Emerging technologies applied to Martian studies combined with wildly fantastical theories to paint Mars as a probable second Earth – long before proposals of terraforming and colonization.

Whenever anyone gets me talking about space and spaceflight, they invariably ask what got me started on ‘all of this space stuff’ in the first place. The short answer is Venus. I became captivated by the planet researching a second grade science project and my interest has continued growing from there. It is a planet, sometimes referred to as Earth’s twin but really more like the Earth turned inside out, that and I can see in the sky! But it’s never been the object that truly captivates me; it’s the hunt to learn about the object. Continue reading “Unraveling Venus” →
I’ve recently found that good things come from using Twitter! Mark Ratterman approached me (via email) asked if I would like to join him and fellow hosts Gene Mikulka, Gina Herlihy, and Sawyer Rosenstein on their podcast Talking Space.
I joined the team this past Sunday for a very fun and interesting discussion. I answered questions and shared my opinions on the Space Shuttle, landing systems, and one-way trips to Mars.
Listen to the episode entitled “A New Look on ‘Vintage Space'”!
In a previous post, I talked about how NASA designed the perfect astronaut – the qualities that were considered vital in selecting the first generation Mercury astronauts. The Soviet Space Program was no different. The organization held its candidates to an equally stringent set of standards as well as a host of unspoken ideal qualities. A cursory look at the Mercury Astronaut selection and the first Soviet Cosmonaut selection reveal two greatly similar processes. But of course, different countries with different resources use different methods. Unsurprisingly, the Soviet Union’s selection and training prior to selecting Yuri Gagarin as its first cosmonaut differs from NASA’s, and some of the main differences between programs are fairly striking. When compared, the agenda of both nations are evident as they determined which man (or men) would represent them as the space age began. So, what makes the perfect Cosmonaut? (Left are three images of the first spacewalk, Cosmonaut Alexei Leonov. 1964.) Continue reading “Designing the Perfect Cosmonaut” →
