Here is the message that was distributed: ”As of 18:30 Z today [Friday, 8/29/04] we went into drag-free control and expect to remain there for the duration of the science phase of the mission. There may be some adjustments to the control system, but pending unforeseen problems, you may want to switch your models to be consistent with drag-free operations.” We are hopeful that the GPB predictions will be much more stable in drag-free operations. Please let us know if you experience any acquisition problems. Thank you for all of your efforts over the last few weeks, as this mission has gotten off to a great start. Best Regards, Julie Horvath NASA SLR Honeywell TSI 301-805-3951 julie.horvath@honeywell-tsit.com From: slrmail@dgfi.badw.de ******************************************************************************** |
