A European mini-space shuttle prototype launched into space Wednesday (Feb. 11) and then zoomed back to Earth in a daring test of innovative technologies for future reusable spacecraft. <\/p>\n
The European Space Agency's car-sizeIntermediate eXperimental Vehicle(IXV) blasted off atop a Vega rocket from the European Spaceport in French Guiana at 8:40 a.m. EST (1340 GMT) Wednesday. The spacecraft was initially expected to launch at 8 a.m. EST, but a problem with telemetry delayed the liftoff within the one hour and 45 minute launch window. The craft came back to Earth about 100 minutes after launch, making a parachute-assisted splashdown in the middle of the Pacific Ocean at about10:20 a.m. (1520 GMT).A recovery ship is stationed near the splashdown zone and is on its way to collect the IXV, European Space Agency (ESA) officials said. <\/p>\n
\"It [the test flight] couldn't have been better, but the mission itself is not yet over,\" Jean-Jacques Dordain, director general of ESA, said through a translator after splashdown was confirmed. \"Now it's going to be necessary to analyze all of the data that was collected throughout the flight.\" [Photos: Europe's IXV Reusable Space Plane Prototype] <\/p>\n
The experimental vehicle is a wingless \"lifting body\" rather than a true space plane. It measures 16.4 feet long by 4.9 feet high by 7.2 feet wide (5 by 1.5 by 2.2 meters) and weighs almost 2 tons (1,814 kilograms) when fully fueled, ESA officials said. <\/p>\n
During today's suborbital flight, the IXV was expected to reach a maximum altitude of about 261 miles (420 kilometers), then barrel back intoEarth's atmosphereat a speed of 16,800 mph (27,037 km\/h). The vehicle was also designed to use an advanced infrared camera and more than 300 other sensors to assess how its thermal protection, guidance and other key systems perform during re-entry. <\/p>\n
ESA considers IXV an important step along the path to mastering autonomous, controlled re-entry technology. <\/p>\n
\"Such a capability is essential for developing a wide range of space transportation applications, including space planes, reusable launcher stages, planetary probes and sample return, cargo and crew transport vehicles,\" ESA officials wrote in anIXV mission FAQ. \"Mastery of re-entry technology could also be useful in innovative future missions for Earth observation, microgravity experimentation, high-altitude atmospheric research and servicing and disposing of future-generation satellites.\" <\/p>\n
IXV is considered \"intermediate\" because it follows the 1998 flight of the Atmospheric Reentry Demonstrator (ARD) capsule and precedes an envisioned space plane project called PRIDE (Program for Reusable In-orbit Demonstrator for Europe). <\/p>\n
The \"PRIDE space plane will be similar to, but smaller and cheaper than, the U.S.s X-37B but, unlike the X-37B, would be managed under civil auspices,\" ESA officials wrote. (The roboticX-37B space plane, which has flown three space missions to date, is operated by the United States Air Force.) <\/p>\n
\"It would be launched by Europes Vega light rocket, orbit robotically, operate in orbit and land automatically on ground in a runway,\" they added. \"The mission will focus on system and technology performance verification under all flight conditions hypersonic, supersonic, transonic and subsonic.\" <\/p>\n
