Europe launched a sleek new space plane more than 250 miles above Earth on Wednesday, testing its maneuverability, on-board guidance systems, and a next-generation heat shield as the experimental vehicle glided through the atmosphere toward a pinpoint splashdown in the Pacific Ocean.<\/p>\n

The test flight marked new territory for Europe and in hypersonic research, laying the foundation for plans to develop a robotic mini-shuttle and reusable launcher stages in the future.<\/p>\n

The flight lasted about 100 minutes from liftoff to landing, beginning with a fiery blastoff aboard a Vega launcher at 1340 GMT (8:40 a.m. EST) from the European-run Guiana Space Center on the northern coast of South America.<\/p>\n

The four-stage rocket flew east from its launch pad, spanning the Atlantic Ocean as it shed its powerful P80 solid-fueled composite motor and two smaller upper stage motors. A Ukrainian-made liquid-fueled engine accelerated the Intermediate Experimental Vehicle to nearly the speed required to achieve orbit, then released the spacecraft more than 200 miles above Earth.<\/p>\n

The IXV passed above ground stations in Africa, radioing its status back to engineers as it reached the top of an arcing suborbital trajectory at an altitude of about 256 miles (413 kilometers).<\/p>\n

Steered by four hydrazine rocket thrusters and two aerodynamic flaps, the IXV dropped into the atmosphere, withstood temperatures near 3,000 degrees Fahrenheit, deployed parachutes and splashed down on target in the Pacific Ocean west of the Galapagos Islands.<\/p>\n

\u201cIt couldn\u2019t have been better, but the mission itself is not yet over,\u201d said Jean-Jacques Dordain, director general of the European Space Agency. \u201cNow it\u2019s going to be necessary to analyze all the data that was collected throughout the flight.\u201d<\/p>\n

Giorgio Tumino, ESA\u2019s IXV program manager, called out status reports on the space plane\u2019s descent. The re-entry demonstrator flew out of range of ground communications antennas about a half-hour after liftoff, and the build-up of plasma around the craft during re-entry blocked radio signals.<\/p>\n

The IXV was programmed to fire thrusters and move its flaps for a series of S-turn banking maneuvers during re-entry, similar to roll reversals executed by space shuttles returning from orbit.<\/p>\n

Tumino announced the acquisition of signals from the IXV at 1502 GMT (10:02 a.m. EST) after the spacecraft was out of the most stressful phase of re-entry.<\/p>\n

A supersonic parachute deployed a few minutes later as the IXV flew at Mach 1.5, then a drogue stabilizing chute ejected before the ship\u2019s 100-foot (30-meter) diameter main parachute unfurled to slow its speed to about 15 mph.<\/p>\n

Officials declared splashdown at 1519 GMT (10:19 a.m. EST), wrapping up a 20,000-mile around-the-world journey.<\/p>\n

More than 300 sensors \u2014 strain gauges, pressure and temperature instruments, accelerometers, and an infrared camera \u2014 were aboard the IXV to record data on the space plane\u2019s test flight. The IXV transmitted the data to engineers before it splashed down.<\/p>\n

The spacecraft\u2019s belly is covered in black ceramic matrix thermal protection panels \u2014 made of a mixture of carbon fiber and silicon carbide \u2014 bolted to the IXV\u2019s structure. Cork-based and silicon-based ablative light-colored materials blanket the space plane\u2019s upper surfaces.<\/p>\n

Once recovery teams retrieve the spacecraft \u2014 which measures about the size of a family car \u2014 it will be returned to Europe for inspections.<\/p>\n

\u201cIt will be hard work, but it will move the frontiers of knowledge further back concerning aerodynamics, thermal issues, and guidance and navigation of such a vehicle \u2014 this lifting body,\u201d Dordain said. \u201cThanks to such analysis, it will be possible to prepare for the next step.\u201d<\/p>\n

European engineers are in the early stages of developing a follow-on automated space plane \u2014 called the Program for Reusable In-orbit Demonstrator for Europe, or PRICE \u2014 that would launch on a Vega rocket into orbit, perform research and deploy or retrieve satellites, and return to Earth for landing on a runway.<\/p>\n

The PRIDE program won funding from ESA member states in 2012 and 2014 for initial studies, but the new space plane needs more money to fly by 2020, as hoped by its backers.<\/p>\n

Officials said lessons learned from Wednesday\u2019s IXV test flight will also aid work on other projects.<\/p>\n

\u201cThis mission will teach us a lot about the technologies we need to apply in new launch systems, in particular when we think about reusable systems,\u201d said Gaele Winters, director of ESA\u2019s launcher directorate.<\/p>\n

The IXV program \u2014 with a cost of about 150 million euros ($170 million) \u2014 also has applications in space science and human spaceflight, officials said.<\/p>\n

Future probes to collect and return samples from other worlds will need an advanced heat shield beyond Europe\u2019s current capabilities, and although Europe has no plans for its own human spaceflight program, such a vehicle would require technologies tested by the IXV.<\/p>\n

Wednesday\u2019s test mission was the first European re-entry testbed to fly since 1998, when ESA launched a blunt Apollo-like capsule on a ballistic flight around Earth on an Ariane 5 rocket. Development of the IXV began in 2002 with ESA-funded studies, and industrial activities started in 2005.<\/p>\n

\u201cEurope has leadership in going to orbit,\u201d Tumino said in an interview before Wednesday\u2019s launch. \u201cWe have the long history of the Ariane family up to the Ariane 5, and we have also the success of the new Vega launcher. We believe the European know-how in getting to orbit is quite good. We also believe that European competencies in operating advanced systems in space is among the best worldwide, with the ATV (space station supply ship) and the Rosetta mission (to comet 67P\/Churyumov-Gerasimenko).<\/p>\n

\u201cWe believe the return capability is running behind,\u201d Tumino said. \u201cWe never closed the loop on the capability to go to orbit, operate in orbit and come back from orbit. The first objective of the IXV mission is we need to gain experience on these types of missions \u2014 the capability to return from orbit.\u201d<\/p>\n

The IXV\u2019s shape is a lifting body \u2014 blend between capsules like Apollo and winged re-entry vehicles such as the space shuttle.<\/p>\n

\u201cWhat we have decided is to avoid these two extremes, and we came up what we believe is an optimal solution, which is a lifting body,\u201d Tumino said, adding such a design \u201cputs together the simplicity of the capsule and the controllability and maneuverability of a winged vehicle.\u201d<\/p>\n

Wingless lifting body vehicles have only been tested in the atmosphere before IXV, officials said.<\/p>\n

\u201cThe novel part of this \u2014 and this is the first time worldwide \u2014 is we are going to test, in flight for a full re-entry, a lifting body,\u201d Tumino said in a pre-flight interview.<\/p>\n

Italy is the prime financial supporter for the IXV and the Vega launcher.<\/p>\n

Roberto Battiston, president of the Italian Space Agency, said Italy will push for a more defined re-entry program within Europe\u2019s space program.<\/p>\n

\u201cWhat to do next is not easy,\u201d Battiston said in remarks after Wednesday\u2019s mission. \u201cDefining the future takes vision, risk and not being afraid of making a mistake. But clearly, in order to develop re-entry technology, we have to have a re-entry program.<\/p>\n

\u201cSomewhere in the future, we should know what to do and what to re-enter \u2014 people, samples, space planes, whatever,\u201d Battiston said. \u201cWe have to have an idea how to proceed. The step we did today is a tremendously important one, but it\u2019s just one step of a long journey.\u201d<\/p>\n

Officials said representatives from ESA member states would meet later this year to discuss the prospects for the PRIDE space plane program, and attempt to identify more concrete objectives for the new spaceship.<\/p>\n

The current concept for PRIDE is for the space plane to be a smaller, civilian-run counterpart to the U.S. Air Force\u2019s X-37B spacecraft, which flies on classified missions and lands on a runway like the space shuttle.<\/p>\n

\u201cPRIDE is exactly a program designed to figure out first what to do next, and then concentrate initial resources on the first phase,\u201d Battiston said. \u201cThis is a long journey and has to be part of a grander project of getting to space and re-entry from the European side \u2014 maybe on another planet, maybe on Earth.\u201d<\/p>\n
