LAUNCH OPPORTUNITY FOR SMALL SPACE EXPERIMENTS POC George Sabestyen tel: 703/883-1010/Jim Jacoby 703/883-2659. NASA has contracted with CTA Space Systems to build and launch the Small Spacecraft Technology Initiative (SSTI) Clark satellite. The launch vehicle for this mission is the Lockheed LLV1 and the launch date is June 1996. The Clark spacecraft will be launched into a sun synchronous 257nm, (476 km) 97.3 degree orbit. The lift capacity of the LLV1 launch vehicle exceeds the Clark spacecraft weight by about 210 lbs. This excess capacity is available to launch a small secondary payload either as a free-flyer spacecraft or as a space experiment without a customer-furnished spacecraft. CTA invites organizations with potential secondary payloads that can meet certain weight, interface and orbit average power constraints to indicate their interest by February 15, 1995. In your reply please indicate the weight, dimensions, attitude, pointing accuracy requirements and status of your potential payload. The secondary payloads will be screened with respect to these characteristics and with respect to any impact they may have on the primary mission. More detailed information will be requested for those potential spacecraft that appear initially to be viable candidates. The secondary payload selection process will be rapid, and cost information will be provided to potential secondary payloads that meet the selection criteria. Please contact Dr. George Sebestyen, CTA Space Systems, 703-883-1010, FAX 703-883-2697, 1521 Westbranch Drive, McLean, VA 22102, or Mr. Jim Jacoby, 703-883-2659. It is the intent that a definitive launch agreement be reached by May 1995. Notice: This is not a Government Solicitation. Any contract negotiated for launch of a secondary payload on the LLV1 will be between CTA and the organization providing that payload.
