X-37B unmanned mini-shuttle completes its OTV Mission 5 with safe landing

by David Todd | Oct 29, 2019 | Military space

After 780 days in orbit (having been launched on 7 September 2017), the US Air Force unmanned mini-shuttle X-73B landed at the Kennedy Space Centre air strip on 27 October. Details of the military mission are mainly secret but are thought to involve both imaging and situational awareness tasks. However, part of the experimentation was known to include a test of heat pipe technology called the US Air Force Research Laboratory Advanced Structurally Embedded Thermal Spreader.
