ESA VV04 Vega Rocket Launches IXV Spacecraft

Replay of the liftoff of Vega VV04 with ESA's Intermediate eXperimental Vehicle, IXV, launched from Kourou, French Guiana on 11 February 2015.

IXV was launched 340 km into space atop a Vega rocket, VV04, from Kourou in French Guiana on 11 February 2015.

After separation from Vega, IXV coasted to 412 km before beginning a punishing glide back through the atmosphere.

During its autonomous flight, IXV tested the latest technologies and critical systems to extend Europe’s capability for space exploration.

ESA’s IXV (Intermediate eXperimental Vehicle) has been “topped off” at the Spaceport in French Guiana as preparations continue for its launch with Vega’s year-opening mission on February 11.

IXV (Intermediate eXperimental Vehicle) was built for the European Space Agency (ESA) by Thales Alenia Space, and is designed to flight test technologies and critical systems for Europe’s future automated reentry systems as they return from low Earth orbit.

The unmanned IXV is to be deployed into a suborbital trajectory by Vega at a 320-km. altitude.

After IXV coasts up to an altitude of 420 km., it will begin the reentry phase, recording data from a large number of conventional and advanced sensors.

The entry speed of 7.5 km. per second creates the same conditions as those for a vehicle returning from low Earth orbit, with IXV subsequently descending via parachutes for a safe splashdown in the Pacific Ocean approximately 100 minutes after liftoff.

Vega’s February 11 mission will mark the lightweight launcher’s second flight within the European Space Agency-managed VERTA (Vega Research and Technology Accompaniment) program to showcase this vehicle's flexibility.

The industrial prime contractor for Vega is ELV S.p.A., a company created by Avio and the Italian Space Agency (ASI) in December 2000.

The IXV (Intermediate eXperimental Vehicle) is being prepared for launch at Europe's Spaceport in Kourou, French Guiana.

IXV will be launched 320 km into space on top of a Vega  rocket, climbing up to 420 km before beginning a long glide back through the atmosphere.

In the process, IXV will gather data on reentry conditions to help guide the design of future spaceplanes. 

ESA’s Intermediate eXperimental Vehicle (IXV) spaceplane on display

This drop-test model of ESA’s Intermediate eXperimental Vehicle (IXV) spaceplane will be one of the star attractions of the Sunday, 5 October ESTEC Open Day.

This replica was built to be dropped from a helicopter and parachuted into the Mediterranean, to ensure the flight model would survive splashdown at the end of its plunge from space.

The actual spaceplane will fly on a Vega launcher this November, coasting as high as 450 km before gliding back to Earth. In the process, it will gather valuable data on atmospheric reentry conditions.

The flight model was, until this week, being tested for space only a few tens of metres away from its drop-test twin, within the cleanroom environment of the ESTEC Test Centre.

With its test programme complete, it has now been flown to Europe’s Spaceport in French Guiana to begin its launch campaign.

Having been designed for a sea splashdown, the drop-test model can readily withstand the Dutch weather. Visitors can view it in its new position outside the Test Centre throughout the Open Day.

The European Space Agency on Tuesday put the final touches to its first-ever "space plane" before blasting it into sub-orbit for tests aimed at eventually paving the way to the continent's first space shuttle.

Assembled in Italy, the Intermediate eXperimental Vehicle (IXV) is undergoing final ground tests at the ESA's headquarters in Noordwijk, north of The Hague, before being shipped to Kourou in French Guiana later this month.

On November 18 the sneaker-shaped IXV will take off aboard ESA's Vega rocket to a height of 450 kilometres (280 miles) where it will go into sub-orbital flight.

Set to fly for 100 minutes, the IXV will then re-enter Earth's atmosphere at a speed of 28,000 km/h over the Pacific Ocean, plunge into the water and then be picked up by a ship.

Bristling with 300 sensors, the IXV will collect myriad data including on what scientists refer to as aerothermodynamics, the heat exchange in gasses and solid surfaces at very high speed, usually supersonic flight.

The data will tell ESA's scientists how the IXV's structure holds up, as well as how its shape performs aerodynamically under extreme conditions.


"The IXV is the starting point and the mission is of huge importance for the future of space shuttles for Europe," Giorgio Tumino, the craft's mission manager, told journalists.

"This mission's key objective is to acquire the capability to come back to earth from orbit," he said.

Built from high-tech ceramics and carbon-fibre, as well as ordinary cork, the IXV is 5.0 metres (16 feet) long and 2.2 metres wide, the same size as a medium-sized car.

The plane could be adapted in future to carry astronauts, Tumino told AFP.

The IXV was developed over five years at a cost of 150 million euros ($193 million).

"If Europe for instance wants to bring back astronauts from the International Space Station to the ground, this (test flight) is a fundamental step," Tumino said.

"We cannot put a person on board a spacecraft without testing its capability to survive re-entry into the earth's atmosphere," he added.

ESA: Europe to Launch Robotic Space Plane Prototype in November

The launch of a robotic space plane prototype in November could pave the way toward the creation of a reusable cargo vehicle that would survive the blistering re-entry into Earth's atmosphere, according to the European Space Agency.

ESA officials plan to launch the unmanned space plane, called the Intermediate eXperimental Vehicle (IXV), on a Vega rocket in early November.

The flight plan calls for Vega to make an eastward flight, different than its usual polar orbit track, to release IXV into a suborbital path that would end in the Pacific Ocean.

Officials with the space agency hope to eventually use the reusable space place as an automated vehicle that will fly through the atmosphere aerodynamically, controlled by thrusters and its surfaces, then splash down safely in the sea.

"In this mission we are not only monitoring the spacecraft all along its autonomous flight, but also tracking its progress back to Earth to a particular spot, this is different [than] what we are used to," Giorgio Tumino, the project manager for IXV, said in a statement.

IXV will include sensors and infrared cameras to examine how heating is distributed across the belly of the spacecraft.

The space plane will also fly with new technologically advanced features.

"The technical advancements that have been made since the first experiments with our Atmospheric Reentry Demonstrator in 1996 are huge," Jose Longo, ESA's head of aerothermodynamics, said in the same statement.

"This is the first flight demonstration of features such as highly advanced thermal structures: thrusters and flaps that are part of the control system, and the 300 sensors and infrared camera to map the heating all along the spacecraft from the nose to the flaps. These things just cannot be tested in the same way in laboratories."



ESA is also going to test an infrared camera on its final automated transfer vehicle (ATV), called Georges Lemaitre, on a mission launching to the International Space Station Tuesday (July 29).

The ATV is designed to break up in Earth's atmosphere during re-entry after it leaves the space station about six months after it docks, according to ESA.

For the first time, ESA plans to track the spacecraft's re-entry using a special infrared camera.

The camera will transmit information to a special pod designed to survive re-entry, which will then send the information on to Earth through the Iridium satellite network.
