At Ny Alesund, Svalbard. Tried test flight of @NASA_CASIE. Power drain anomaly. Back to the hanger to troubleshoot. Hopefully tomorrowabout 11 hours agofrom web
11pm - sun high in the sky. Sierra autopilot glitch being worked. Hope test flight early tomorrow does well - then science Wed!1:56 PM Jul 13thfrom web
At Ny Alesund research station in Svalbard. What a spectacular setting. Hopefully first science flight on CASIE wednesday.8:56 AM Jul 13thfrom web
Just landed in Longyearbyen, Svalbard. Spectacular actic views. On to Ny Alesund soon4:47 AM Jul 13thfrom TwitterBerry
About to leave Oslo for Longyearbyen, svalbard via Tromso - studying the earth rocks!12:35 AM Jul 13thfrom TwitterBerry
@jsalsman final limitation is orders of magnitude larger interference from parent star signal - typically 10**9 or more12:07 AM Jul 13thfrom TwitterBerry
@jsalsman next limitation is can't hold interferometric lock over long time periods with low signal and rapid relative s/c movement12:05 AM Jul 13thfrom TwitterBerry
@jsalsman prime limitation is that planetary signals are very weak. Need large aperture or very long integration time12:04 AM Jul 13thfrom TwitterBerry
@jsalsman I could be completely wrong - but see numerous reasons why Hubble etc. Are orders of magnitude off from what's needed11:53 PM Jul 12thfrom TwitterBerry
@jsalsman frankly for a space system to perform a difficult function like exo-planets it needs to be designed from the start to do so11:52 PM Jul 12thfrom TwitterBerry
@jsalsman 1)Signal from planetary ozone far to small, 2) hubble etc. Don't have detectors, sensitivity or time/position accuracy.1:27 PM Jul 12thfrom TwitterBerry
Just arrived is Oslo, Norway - tomorrow off to Svalbard and our research mission CASIE12:43 PM Jul 12thfrom TwitterBerry
@jsalsman the satellites are moving too fast relative to each other to get accurate enuf relative positions with approp time accuracy10:29 AM Jul 12thfrom TwitterBerry
@jsalsman to do interferometry one needs to reconstruct pieces of wavefront. Need relative position (inc time) to better than wavelength10:26 AM Jul 12thfrom TwitterBerry
