MSL Sky Crane on Scientific American’s Guest Blog

Regular readers of Vintage Space will know that I’m fascinated by landings – the challenges of both landing on Earth and on other planets. Within this latter vein, I’ve lately become completely mesmerized with the Mars Science Laboratory’s (MSL’s) Sky Crane. Finally, I’ve found a fantastic outlet for an article I’ve been wanting to write for months about the Sky Crane, where it came from, and how it works. With this pieces, I’m very pleased to be a contributing member to the Scientific American’ Guest Blog! Check out the full article, which includes a video of MSL’s recent launch, on Scientific American’s website. (Pictured, the Sky Crane lowering the SUV-sized rover Curiosity to the surface of Mars. Don’t you want to know all about it?)

NASA’s First Interplanetary Journey: Venus

Venus has always held a certain fascination for sky-gazers. It’s the brightest object aside from the Sun and the Moon and it’s been named for three goddesses of love: the Roman Venus, the Greek Aphrodite, and the Babylonian Ishtar. As naked eye astronomy and myth gave way to scientific observation, Venus took on a different personality. Early Earth-based observations suggested it was a younger world and a tropical paradise, but better technology revealed it was hot and carbon dioxide rich. But there’s no better way to learn about a planet than to visit it. (Left, an artist’s concept of Mariner 2 – the first interplanetary spacecraft.)

In 1967, NASA developed a mission to send men to Venus. But before getting into the proposed manned mission, it’s worth stepping back to look at the state of NASA’s knowledge of Venus and its understanding of the interplanetary space a mission would have to go through to get there. Before this manned mission proposal, NASA had only sent one mission to Venus – Mariner 2.  Continue reading “NASA’s First Interplanetary Journey: Venus”

Carnival of Space #223

It’s been a busy week for space blogs, so we’ve got a packed Carnival of Space. Let’s look at what’s been going on in my favourite way: starting from way out in deep space and coming all the way back home to Earth. (Fun vintage space picture of the day: the Apollo 1 crew relaxes in a pool during egress training. That looks like a fun day at work!) Continue reading “Carnival of Space #223”

The Life and Times of Pluto

This week, three people have approached me wondering why Pluto isn’t a planet anymore. My brief explanation of “it doesn’t meet the characteristics of a planet” didn’t set too well; they grew up with Pluto, they want it back! They want their children to grow up with Pluto! I realized after these exchanges that although the fate of Pluto has been a news feature since it’s contestation began a little over a decade ago, not many people know the details behind the decision. Each of the people I spoke to this week suggested I explain the story in more complete detail on my blog. As so, by request: a brief history of the outer planets and the rise and fall of Pluto. (Left, Pluto.) Continue reading “The Life and Times of Pluto”

Before This Decade is Out: Robotic Mars Edition

Decades make great sales tools. Kennedy used a decade timeframe to sell American on the moon in 1961. Robert Zubrin recently tried the same pitch and called for a manned mission to Mars by the end of a decade (Zubrin’s been pitching a decade-long manned Mars program since the 1980s to no avail). A decade is a nice  round number, and when you’re at the start of a decade – like the year 1961 or 2011 – people (namely Congress and taxpayers) can easily contemplate the end of a decade as a timeframe. But it isn’t  only large-scale manned programs that use a round decade as a sales tool. Recently, the National Research Council’s Committee on Planetary Science in cooperation with NASA released an outline of its planetary goals for the coming decade. Where Mars in concerned, there is a pretty impressive program in the works from 2012 to 2023. But unlike the moon landing, bottomless funding isn’t going to achieve the goals at any cost. Instead, the next decade on Mars (pictured) will face certain challenges to meet the decadal goal.  Continue reading “Before This Decade is Out: Robotic Mars Edition”

Carnival of Space #216

Welcome to another installment of the Carnival of Space! Some neat things on the table this week, so let’s get to it. (Not exactly a hover craft, Dave Scott practices how to manoeuvre in anticipation of an EVA. If you look closely, it appears as though he’s doing this training in a shirt and tie. 1962.)

RATs and Monuments on Mars

In a previous post, I made the comment that I don’t necessarily think humans ought to colonize other planets; at least, not until we know a lot more about the environment upon which we intend to force ourselves. Manned exploration is another story. Sending men to another planet to survey the environment is much simpler than trying to replicate a man’s honed skills and keen mind in a machine – aside, of course, from the challenges associated with getting him there in the first place. Such tools exist on the recently silent Mars Exploration Rovers (MER) Spirit and Opportunity. But the rover’s tools serve an unlikely second purpose. They stand as a tribute to those lost during the terrorist attacks on the World Trade Centre on September 11, 2001. (Left, MER rover Spirit captures its own shadow. Mars, 2004.)
