IXV Makes a Splash as ESA Spaceplane Effort Treads Water

TURIN, Italy – A European spaceplane know-how demonstrator was efficiently launched Feb. 11 on a 100-minute suborbital mission that took it into house for almost an hour earlier than it re-entered Earth’s environment and splashed down within the Pacific Ocean greater than midway around the globe.

The 5-meter-long Intermediate Experimental Automobile (IXV) efficiently despatched telemetry because it re-entered the environment, delivering knowledge from its sensors and making bodily restoration of the ship much less essential.

“So as to develop reentry know-how, we’ve got to have a reentry program.”

Supported by flotation gadgets, the car was awaiting pickup by the identical Italy-based ship that acquired the telemetry and took images of the car within the water.

European Area Company officers stated the parachutes had functioned as laid out in slowing IXV’s descent, and that its flotation gadgets – there are 4 of them – additionally deployed appropriately.

The launch prolonged the right document of Europe’s Italian-led Vega small-satellite launcher – 4 successes in its first 4 missions. Vega program officers stated that not solely has the rocket made historical past as the primary European rocket to conduct a flawless first 4 flights, but it surely has executed so with very completely different mission profiles.

“All that we have to work on now’s the value,” stated one European authorities official, referring to Vega’s present price construction, which is taken into account too excessive for the market.

Reflecting the predominance of Italy within the IXV program, the mission was managed from ALTEC, the Superior Logistics Know-how Engineering Heart, which is owned by Thales Alenia Area, the Italian Area Company, Italian aerospace conglomerate Finmeccanica and Italy’s Piedmont regional authorities.

The IXV mission price European Area Company governments about 210 million euros ($275 million), together with 40 million euros for the Vega launch.

The launch had been delayed from November due to a dispute between ESA and the French house company, CNES – which has prime launch authority as a result of Europe’s Guiana Area Heart spaceport is on French territory in French Guiana – over the protection of Vega’s uncommon flight profile.

Most launches from the European spaceport, positioned on South America’s northeast coast, head north over the ocean. However IXV required a Vega flight heading useless east, over the city of Kourou, French Guiana.

The November IXV launch was scrapped when CNES declined to present launch authorization. The flight trajectory was barely modified – forcing a change-out of the Vega flight management software program – and rescheduled for February.

The Feb. 11 flight additionally bore the stamp of continued concern for flight security. The countdown was stopped 4 minutes earlier than liftoff to present spaceport range-safety officers time to confirm the distinctive telemetry measures they added for the flight to cowl these a number of seconds when Vega, its solid-fueled second and third levels full, flew over Kourou after liftoff.

Weighing some 1,844 kilograms and chock-full of sensors, the IXV is the primary European atmospheric re-entry experiment since 1998, when a capsule was launched right into a suborbital flight in what was meant to be a sustained program on re-entry applied sciences.

It was to not be. The IXV venture survived solely due to the insistence of the Italian authorities, which can also be the principle backer of the Vega rocket. The IXV employs a lifting-body design with no wings, however two flaps for management throughout re-entry. European officers stated it’s thus a midpoint between the U.S. shuttle and the Russian Soyuz capsule.

What occurs subsequent for Europe’s re-entry know-how plan is unclear. An Italian-led venture referred to as PRIDE, or Program for Reusable In-orbit Demonstrator in Europe, acquired solely lukewarm assist from European governments after they met in December to repair technique and spending plans.

Robert Battiston, president of the Italian Area Company, stated after the IXV launch that he hoped the mission’s success would catalyze assist for PRIDE as a part of a broader European program on rocket reusability, re-entry applied sciences and planetary exploration.

“So as to develop reentry know-how, we’ve got to have a reentry program,” Battiston stated.
