Europe's first-ever "space plane" will be launched on February 11 next year, rocket firm Arianespace says after a three-month delay to fine-tune the flight plan.

The unmanned, car-sized vessel will be sent into low orbit by Europe's Vega light rocket, on a 100-minute fact-finding flight to inform plans to build a shuttle-like, reusable space vehicle.

Dubbed IXV, for Intermediate eXperimental Vehicle, the plane will be boosted from Europe's space pad in Kourou, French Guiana, and separate from its launcher at an altitude of 320km.

The European Space Agency website says it will attain an altitude of around 450km before re-entering the atmosphere at an altitude of 120km - representative of a return mission from low orbit.

The vessel is expected to collect data on its hypersonic and supersonic flight phases, before plunging into the Pacific Ocean with a parachute.

The initial launch had been scheduled for November 18, but Arianespace in October announced a postponement "to carry out additional flight trajectory analyses".

"Based on joint work by ESA (the European Space Agency) and CNES (the French space agency), the date for the IXV mission to be launched by Vega has been set for February 11, 2015," the company said in a statement on Friday.

Developed over five years at a cost of 150 million euros ($A225 million), the IXV is the testbed for a reusable vehicle that may one day be able to land on a conventional runway on Earth after a mission to space.

This could be useful for bringing astronauts back from the International Space Station (ISS).

The only craft currently able to ferry astronauts to the ISS and back is Russia's Soyuz.
Last month saw two major setbacks for the space industry.

On October 28, an Orbital Sciences Antares rocket exploded shortly after launch on what was to be a supply mission to the ISS, followed three days later by the crash of Virgin Galactic tourist space plane SpaceShipTwo on a test flight, killing one of two pilots.
