China s Long March 8 Rocket Makes Successful Debut in Step Toward Reusability – Parabolic Arc

by Douglas Messier Managing Editor China’s newest booster, Long March 8, successfully placed five satellites into sun-synchronous orbit on Tuesday from the Wenchang Satellite Launch Center in a step toward partial reusability. The medium-lift booster blasted off at 12:37 p.m. local time from Hainan island carrying the classified XJY-7 remote sensing technology test satellite and four smaller payloads. “The relevant satellite payloads will verify the microwave imaging and other technologies in orbit, and carry out space science, remote sensing, and communication technology experiments and applications,” the China National Space Administration said in a press release. Long March 8 first stage with side boosters lands on offshore platform.

Virgin Galactic Looks on the Bright Side After Launch Abort – Parabolic Arc

But, when it came time for the rubber to meet the oxidizer, the whole thing suddenly flamed out. The hybrid engine on Virgin Galactic’s SpaceShipTwo VSS Unity failed to fire properly on Saturday, sending the suborbital rocket plane, pilots David Mackay and C.J. Sturckow and a load of NASA-sponsored experiments into a rapid descent and landing back at Spaceport America, instead of a graceful parabolic arc into suborbital space. Although the misfire will cause another delay in a flight test program that has already lasted for more than decade, Virgin Galactic emphasized the positives.
