Mars: A Planetary Star
John O’Neill’s August 5th blog article, “All Eyes on Mars as Curiosity Prepares to Land,” focused on the suspense of waiting for the rover to land safely on Mars. The two-thousand pound (900 kg) rolling geology lab did in fact make a flawless landing on August 6th and with its touchdown, it revived interest in the Red Planet. From the description of Curiosity given on Jet Propulsion Lab’s website, the rover truly belongs in a science fiction tale.
- body: a structure that protects the rover’s “vital organs”
- brains: computers to process information
- temperature controls: internal heaters, a layer of insulation, and more
- “neck and head”: a mast for the cameras to give the rover a human-scale view
- eyes and other “senses”: cameras and instruments that give the rover information about its environment
- arm and “hand”: a way to extend its reach and collect rock samples for study
- wheels and “legs”: parts for mobility
- energy: batteries and power
- communications: antennas for “speaking” and “listening”
The size of a small SUV, the rover has already begun its mission to “search areas of Mars for past or present conditions favorable for life, and conditions capable of preserving a record of life.” It is equipped to gather data, take photographs and then send the information back to JPL. In other words, Curiosity is our roving reporter on Mars. Kind of gives a whole new concept to being a “foreign” correspondent, doesn’t it?
With Curiosity running around on Mars, what better time is there to combine science with fiction and review some of the stories written about the Red Planet? A good start is Gordon Van Gelder’s anthology, Fourth Planet From The Sun. It was published by Thunder’s Mouth Press in 2005, about a year after the Mars rovers Spirit and Opportunity started to send back their photos of Mars. It is fitting that with the successful landing of Curiosity, we take another look at it.
