Sincerely hope all you UMSFers on the West Coast are OK! Read Emily's blog....

Just out of curiosity ... does the JPL have backup mission control centers somewhere in the US?
Otherwise I've been lucky with disasters. Felt a few Earthquakes in Switzerland, typhoons in HK and Taiwan & was in Malaysia during the boxing day tsunami but well away from the coast, and of course still remember the big chemical fire in Basel, Switzerland (not really a natural disaster) -------------------- |

Just out of curiosity ... does the JPL have backup mission control centers somewhere in the US? I don't believe they do, but it sounds like all mission teams have a contingency plan for earthquakes. Here's the Cassini plan (extract taken from the Cassini website in 1999): QUOTE A Major Earthquake in California. Yes, we even have plans for this goblin! If a major earthquake were to strike, communication lines between JPL and the remote Deep Space Network, which we use to communicate to the spacecraft, might be broken for hours to possibly days. And with a probability of about 2 percent per year of a "major" earthquake, we'd better be ready for it if it happens. Our strength in this area is Cassini's distributed network, with scientists planning observations all over the country. The spacecraft sequence files, not to mention the science observations, will be stored in more than one location. Of course, after an earthquake we'd have to make sure our operations team can get somewhere secure to continue to plan spacecraft events, but with sequences being 28 days long, it's likely we'll have some time to recover and get a team to develop the next 28-day sequence before the current sequence ends. -------------------- "I got a call from NASA Headquarters wanting a color picture of Venus.
