Today the European Space Agency’s test spaceplane went on a successful 100-minute, remotely-operated ride along the equator from Kourou, French Guiana, to the Pacific Ocean, just west of the Galapagos islands.
IXV was launched 340km into space on top of a Vega rocket, flight VV04, had climbed to 412 km before began a long glide back through the atmosphere. During the flight, IXV tested the latest technologies and critical systems to help guide the design of future spaceplanes and reusable launchers.
We covered the event live based on ESA’s live video and Twitter feed:

Update 11:
Shortly, Libreville station will lose radio contact, as expected, followed by Malindi station. Then, no news from #IXV until after reentry

Update 12:
According to ESA everything seems OK!

Update 14:
This is how the equatorial trajectory of the spaceplane looks like:
Update 15:
ESA reports: In 7 minutes, ESA’s spaceplane will dive into Earth’s atmosphere at circa 120km altitude moving at 27,000 km/hr. All systems looks ok, both in space and on the ground.
Update 16:
And we have a spaceplane again!

Update 19:
And splashdown! European Space Agency’s Intermediate eXperimental Vehicle (IXV) is back on Earth, the 100 minutes long mission has been successfully completed.
This fine time-lapse video below, shows IXV’s preparation, fairing encapsulation, transfer to the Vega mobile gantry and upper composite integration on the Vega launcher.
