  1. http://twitpic.com/ad6h1 - Actually did useful work wile the team fixed CASIE-SIERRA problem. Science flights tomorrow
  2. At Ny Alesund, Svalbard. Tried test flight of @NASA_CASIE. Power drain anomaly. Back to the hanger to troubleshoot. Hopefully tomorrow
  3. @jsalsman because its not moving very fast relative to other sensors. Key issue though is very low signal of exo-planet atmospheres
  4. 11pm - sun high in the sky. Sierra autopilot glitch being worked. Hope test flight early tomorrow does well - then science Wed!
  5. At Ny Alesund research station in Svalbard. What a spectacular setting. Hopefully first science flight on CASIE wednesday.
  6. Just landed in Longyearbyen, Svalbard. Spectacular actic views. On to Ny Alesund soon
  7. At Tromso for a short stop - North of the arctic circle!
  8. About to leave Oslo for Longyearbyen, svalbard via Tromso - studying the earth rocks!
  9. @jsalsman final limitation is orders of magnitude larger interference from parent star signal - typically 10**9 or more
  10. @jsalsman next limitation is can't hold interferometric lock over long time periods with low signal and rapid relative s/c movement
  11. @jsalsman prime limitation is that planetary signals are very weak. Need large aperture or very long integration time
  12. @jsalsman I could be completely wrong - but see numerous reasons why Hubble etc. Are orders of magnitude off from what's needed
  13. @jsalsman frankly for a space system to perform a difficult function like exo-planets it needs to be designed from the start to do so
  14. @jsalsman 1)Signal from planetary ozone far to small, 2) hubble etc. Don't have detectors, sensitivity or time/position accuracy.
  15. Just arrived is Oslo, Norway - tomorrow off to Svalbard and our research mission CASIE
  16. @jsalsman the satellites are moving too fast relative to each other to get accurate enuf relative positions with approp time accuracy
  17. @jsalsman to do interferometry one needs to reconstruct pieces of wavefront. Need relative position (inc time) to better than wavelength
  18. Having beer, sousage and potatoes at the Munich airport - yum!
  19. @jsalsman tethered baloons much easier to synchonize - slow relative velocities
  20. Just landed in Munich - early (good German efficiency - way to go Lufhanza!). Off to Oslo in two hours
