![]() It should be remembered that while NASA had some tracking ships, most of the tracking ships used by NASA were not actually owned by NASA and were made available to NASA as required. ![]() I agree that the USNS Range Sentinel wasn't used for the manned program. This ceased to be necessary with the advent of the TDRSS network of satellites. It was also used, along with the USNS General Hoyt S. It was used up to Apollo 11 and then again for the Skylab missions. While the USNS Redstone was part of ETR support, it was definitely used in support of NASA's Manned Space Program. OK, but it seemed like about T-3 days they could be seen in port but come shuttle launch day they were nowhere to be found. The telemetry needs for the launch phase of most vehicles was covered by the Cape, JDMTA, Antigua and Ascension. It wasn't TDRSS that caused the demise of the Redstone, it was lack of need. The Redstone was used for ETR support and not part of the NASA tracking network (manned or unmanned) nor the AF sat control network. In the 70s, most of the tracking ships were either decommissioned or converted to other uses. The Range Sentinel wasn't deliver until 1971 and it was specifically for SLBM testing support. So then USNS Redstone was also uninvolved with the early space shuttle program? That's a bit surprising.Īlways assumed that these range telemetry ships were part of the worldwide tracking network up until TDRSS became operational?
