Boeing's Starliner crew capsule, making a repeat test flight in a third attempt to reach the International Space Station, finally closed in on the lab complex Friday, executing a series of rendezvous maneuvers while engineers investigated problems with two thrusters and the spacecraft's cooling system. Approaching from behind and below, the unpiloted Starliner was expected to home in on the space station using a high-tech robotic vision system, moving in for docking at the lab's forward port around 7:10 p.m. EDT. "From Starliner's cameras, we are seeing ISS," Rob Hayhurst in mission control at the Johnson Space Center radioed the station crew as the capsule slowly approached. "Awesome, we're waving, can you see us?" astronaut Robert Hines joked. "Great news, that's really good to hear. We're getting squared away up here and ready to catch her."

NASA While no astronauts were on board the Starliner, Boeing took advantage of the test flight to send up about 500 pounds of equipment and supplies along with "Rosie the Rocketeer," an instrumented mannequin collecting data on the cabin environment real astronauts will experience during operational flights. Launched Thursday from Cape Canaveral atop a United Launch Alliance Atlas 5 rocket, the Starliner reached its planned initial orbit despite the premature shutdown of two thrusters, automatically switching to a backup jet in the same rocket pad to continue the critical maneuver. At the same time, engineers were monitoring a spacecraft cooling problem that appeared to stabilize after the ship reached orbit. Overnight, however, one of the capsule's two cooling loops later ran into problems, forcing flight controllers to make manual adjustments. Without providing details, Boeing said in a statement "the thermal subsystem is maintaining stable temperatures" and a spokesman said the Starliner's approach to the station could be adjusted as required to maintain proper temperatures if necessary. Otherwise, Boeing reported the Starliner's guidance, navigation and control system was working normally, flight software was running smoothly, the ship had good communications through NASA's Tracking and Data Relay Sa . . . read the full article here.
