Wow, in 10 years I'll be 68 years old. By that age many people retire from work, but space science is so much fun that many of us work long into our 70's or even 80's. Dr. Bill Gordon, who invented the Arecibo Telescope, is 90 years old!
I am working on the planning of a spacecraft call the "Magnetospheric Multiscale Mission". It is designed to fly in the year 2012, and we hope will take data for 5 years or more. So I hope I will still be analyzing the data from it in 2018! When science stops being fun, I'll retire but I don't expect that very soon.
For more information on the MMS mission, see
http://MMS.space.swri.edu. It will be four spacecraft flying in formation, like the Cluster mission. By doing that we can understand the process of "reconnection" or "merging" that allows magnetic energy to be released into particle energy. This process happens on the Sun and in the Earth's magnetosphere, but it's a lot easier to fly a spacecraft near the Earth than near the Sun!
