Robotic armada is invading Mars from all directions By Ken Kremer The Red Planet is getting a whole lot of attention from Earthlings right now, and it’s like never before in the history of humanity and space exploration. Currently, an armada of five spacecraft from Earth are actively exploring the vicinity of Mars, including a trio of orbiters and a duo of rovers. All but one of those space probes is from NASA. The lone exception being the Mars Express (MEX) orbiter from ESA, the European Space Agency. And later this Fall, two additional probes - NASA’s MAVEN and India’s Mars Orbiter Mission (MOM) - will blast off to embark on long interplanetary voyages in search of new Martian discoveries beginning late in 2014. Joining MEX, NASA has two orbiters and two surface rovers plying the Martian skies and plains. Circling overhead are Mars Odyssey (MO) and Mars Reconnaissance Orbiter (MRO). Trundling below are the Martian sister rovers, Opportunity and Curiosity. The spacecraft literally form an invasion fleet embarked on a coordinated attack plan that’s directed by an elite group of highly talented engineering and science ‘Generals’ so as to reap every last drop of scientific research possible - and for as long as possible. Every one of these unique spacecraft is a ‘priceless asset’ as Prof. Steve Squyres, Opportunity’s Principal Investigator of Cornell University, or lead scientist, is fond of saying. Besides conducting breathtaking science in their own right, the MO, MRO and MEX orbiters relay and transmit virtually all of the gorgeous photos and unprecedented research data collected on the ground by NASA’s Curiosity and Opportunity rovers back to huge dish antenna receiving stations spread across Earth. So let’s briefly review the history, goals and results of the current quintet of our Martian fleet and learn what’s new and upcoming in the near term. 12 12 www.RocketSTEM.org
