An amazing video was released recently by NASA showcasing the 13 mile journey of NASA’s Opportunity rover across the Martian landscape from one crater to another. Sure the video isn’t flashy and not for those with the limited attention spans of our MTV and Twitter society, but at least it is more interesting than the 2000 dual-combo movie stinkers Red Planet and Mission to Mars. As an aside, has Val Kilmer even done a good movie since Heat? Sure, his turns in The Saint and as the voice of KITT in the Knight Rider reboot were alright, but The Steam Experiment? I don’t even need to make a joke here, do I?
Anyway, in honor of this fascinating achievement, I wanted to examine some of the interesting patents related to Mars exploration.
Mars exploration rover Athena — US D487,715 S
The first is a design patent of the rover itself. What is most interesting to me is the 6 wheel design, to help the rover navigate the rocky terrain on Mars, and the large solar arrays that provide power to the rover’s lithium ion batteries.
Bacillus pumilus SAFR-032 isolate — US 7,262,047 B
The patent relates to isolating a particular type of bacteria spore that is capable of surviving typical spacecraft sterilization processes, and is resistant to UV rays that are present on Mars. If present and future rovers are going to test for characteristics related to past or current life on Mars, they have to be certain that the life is not actually bacteria from Earth that happened to survive the treacherous journey to Mars.
Lithium Ion Electrolytes and Lithium Ion Cells with Good Low Temperature Performance — US 2009/253046 A1
This lithium ion battery is designed with the future in mind. It must be lightweight, provide enough energy to power several pieces of electronic equipment, work in the extreme temperature ranges, and have a long life span. No, we aren’t talking about powering the photographer for your third cousin’s wedding reception, but rather powering future Mars rovers and landers.
Method and Apparatus for Powered Descent Guidance — US 2010/0228409 A1
When future space probes reach Mars, what is the most important thing when deploying the lander and rover? Why, not crashing it and losing the hundreds of millions of dollars spent on the project, of course. Unless that probe contains Val Kilmer, then by all means (just kidding–man, he’s really taking a beating today). An accurate landing is essential for all further missions, and therefore the technology to get it right needs to be put in the hands of some very smart people.
Next time: I offer Val Kilmer five bucks to take my abuse with kindness and good humor. He accepts as he really needs the money until the Top Gun sequel starts shooting.
