How Much Science Data Has The Mars Reconnaissance Orbiter Sent To Earth?

Imagine being able to watch three months’ worth of high-definition space video sequentially — maybe real-time coverage on the International Space Station, or getting to watch the Mars Reconnaissance Orbiter zoom across the Red Planet over and over again. Well, that’s how much science data MRO itself has sent back  in 10 years of operations, NASA said.

“The sheer volume is impressive, but of course what’s most important is what we are learning about our neighboring planet,” stated the Jet Propulsion Laboratory’s Rich Zurek, the project scientist for the Mars Reconnaissance Orbiter.

MRO has sent back 200 terabits, all told. It’s a wealth of science data on its own merits as it examined evidence of water, ancient volcanoes and other parts of the Red Planet’s history from above. The spacecraft, however, also serves as a relay for the NASA Curiosity and Opportunity rovers on the surface.

“Data gathered by the orbiter’s instruments and relayed from rovers are recorded onto the orbiter’s central memory. Each orbit around Mars takes the spacecraft about two hours. For part of each orbit, Mars itself usually blocks the communication path to Earth,” NASA stated.

“When Earth is in view, a Deep Space Network antenna on whichever part of Earth is turned toward Mars at that hour can be listening. Complex preparations coordinate scheduling the use of the network’s antennas by all deep-space missions — 32 of them this month. Mars Reconnaissance Orbiter typically gets several sessions every day.”

Once the Deep Space Network antennas in Spain, California and Australia pick up the data, JPL organizes them into their separate “products”, ranging from radar measurements from above to data picked up by a rover below. The information is then sent to various organizations around the world that have interests in the work.

MRO arrived at Mars in 2006 and its mission has been extended three times, with the latest one taking place in 2012. NASA also relays information from the planet using Mars Odyssey, which has been there since 2002.

    Thanks for the interesting article. Such a amazing achievement yet space exploration has a long way to go still.
    I wish I could be alive 100 years or more from now to see what mankind will have achieved. I think the phrase Science Fiction will have been replaced by the phrase Science Future Reality. I firmly believe that if it can be imagined then it is possible!

    According to one eminent scientist, humans will be extinct in 100 years. Enjoy it while you can.
