\nA view of the marine tracking station antenna on the recovery ship, Nos Aries<\/i>, now in the Pacific Ocean readying for next week\u2019s crucial IXV mission.\n<\/p>\n
\nThe ship will support the 100-minute flight of IXV, which will test crucial new European reentry technologies. IXV is set for liftoff at 13:00 GMT on 11 February.\n<\/p>\n
\nFollowing the ballistic phase, reentry \u2013 IXV\u2019s most critical phase \u2013 will start at 120 km altitude, when the craft\u2019s aerodynamic \u2018lifting body\u2019 shape slices into the atmosphere at 27 000 km\/h, which mimics a spacecraft returning from a typical low-orbit mission.\n<\/p>\n
\nThis is when ground teams in Europe and on the ship will be most anxious, as nothing will have been heard from the wingless spaceplane since before the start of reentry.\n<\/p>\n
\nReentry starts about 64 minutes into flight and lasts about 20 minutes. During reentry, the thermal protection on the underbody will be exposed to temperatures of around 1700\u00baC \u2013 hot enough to melt nickel.\n<\/p>\n
\nMeanwhile, in the Pacific Ocean, slightly north of the equator and about 25 km from the target splashdown spot near 3\u00b0N \/ 123\u00b0W<\/a>, the antenna on the Nos Aries will be pointing at IXV\u2019s expected trajectory and listening for \u2018AOS\u2019 \u2013 acquisition of signal. Hearing it will indicate that reentry has gone well.\n<\/p>\n \nExperts from the Agency’s Estrack ground station network will be on the ship to support the crucial tracking activity.\n<\/p>\n \nMore about IXV<\/a>\n<\/p>\n \nMore about ESA’s tracking station network<\/a>\n<\/p>\n \nFollow IXV on Twitter @esa_ixv<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" \t\t\t\t\t \nA view of the marine tracking station antenna on the recovery ship, Nos Aries<\/i>, now in the Pacific Ocean readying for next week\u2019s crucial IXV mission.\n<\/p>\n \nThe ship will support the 100-minute flight of IXV, which will test crucial new European reentry technologies.
