Page 1JSOC Overview August 2007 HMI Status HMI is virtually done. –Virtually  similar to but not in fact –Front window issue resolved, flight window now at LMSAL will be installed next week –Light leaks to be fixed next week. –Some electronics boards need conformal coating –Some software issues remain Vibration and EMI/EMC testing done Thermal Balance and Thermal Vacuum testing starting week after next. In Air and Vacuum Calibration next few weeks. Pre-Ship Review set for 25 Sept. Ship date estimated 5 October. Launch date slip to probably 15 Jan 2009 pending review at HQ. Some serious implications from delay

Page 2JSOC Overview August 2007 JSOC-SDP Status Capture system complete, waiting testing with DDS at White Sands DRMS and SUMS virtually done Level-0 work progressing, to be done by delivery Level-1 work to start after delivery Getting serious about work on basic pipeline modules
