Building an IT Infrastructure Around Mars

bfwebster writes "Space.com has an article talking about the efforts to observe the arrival of the Phoenix lander on Mars this coming May using current Mars orbiters. This community will likely be intrigued to see the ways in which NASA is using existing landers and orbiters to prepare for, and then monitor, that landing. This includes using the landers Spirit and Opportunity to simulate transmissions from Phoenix as a testing procedure in advance of the actual landing; using the Odyssey orbiter as a high-speed data transmission link from Phoenix to Earth during the landing; and using the Mars Reconnaissance Orbiter and Mars Express orbiter as backup data stores for Phoenix data transmissions during the descent. How long until we get a terabyte solid-state dataserver (running IPv6, natch) in orbit around Mars?"

One should be engaged (and I hope the folks at NASA are reading this) in a serious discussion of what is the information retrieval rate of a space probe (robotic explorer, etc.) vs.a human being? http://astrobiology.arc.nasa.gov/news/expandnews.cfm?id=849

According to Kathy Clark, chief scientist for NASA's Human Exploration and Development of Space (HEDS), while the Sojourner Mars rover was a tremendous achievement, "Sojourner spent two weeks analyzing half a dozen Mars rocks. A human geologist could have done that same work in 30 minutes--then turned the rocks over to see what was hiding underneath." A biased source, but it's probably true - a human could travel the four miles Spirit has travelled in several years in about an hour. A little slower considering the sampling they'd be doing, but not by that much - you can pick it up and look at it on the way home (or when you get back to Earth). They could kick a deeper hole with their shoe in seconds than the rover can dig, ever.
