WSJ - The Spacex Dragon capsule appeared to flawlessly complete a series of maneuvers around the international space station Thursday, clearing the last major hurdle before a historic docking attempt planned for Friday.
The tests demonstrated that sensors, navigation equipment, communications links and computer-controlled propulsion systems aboard the Dragon capsule were all working properly.
The so-called fly-under maneuver commanded the cone-shaped capsule—built and operated by Space Exploration Technologies Corp.—to catch up to and then pass the space station. The highlight of the test, occurring before 7:30 a.m. Eastern time, had the spacecraft float by about 1.5 miles below the station.
National Aeronautics and Space Administration officials said preliminary indications were that Dragon's thrusters, laser-assisted sensors and thermal imaging instruments seemed to pass the preliminary rendezvous tests with flying colors, but analysis of the data was expected to continue through the day.
