This reminds me that I have to set up an "evening out at the pub" with a friend
of mine here, who works for the ESA (European Space Agency) on two different
projects that have gotten a mention here lately. First, and most immediately
relevant, he was in charge of the database operations for the Rosetta project,
so I'll ask him what's up now that Philae has rolled away the stone and come
back to life.
But the other, more long-term project he works on is that he is in charge of
the database used to store info on comets, asteroids, and other space junk that
might hit the earth. Suffice it to say that this DB is *huge*, and presents
some problems we've discussed before (I used to work in DB, and was curious)
about the relational design of the data and issues he might face with
optimization and speed of retrieval.

Subject: [FairfieldLife] Philae only playing possum
The European Space Agency (Esa) says its comet lander, Philae, has woken up
and contacted Earth.
Philae, the first spacecraft to land on a comet, was dropped on to the surface
of Comet 67P by its mothership, Rosetta, last November. It worked for 60 hours
before its solar-powered battery ran flat. The comet has since moved nearer to
the Sun and Philae has enough power to work again, says the BBC's science
correspondent Jonathan Amos.
An account linked to the probe tweeted the message, "Hello Earth! Can you hear
me?" On its blog, Esa said Philae had contacted Earth, via Rosetta, for 85
seconds on Saturday in the first contact since going into hibernation in
November.
We don't leave anyone behind.https://www.youtube.com/watch?v=Ue4PCI0NamI
