The last test launch of the Soyuz-2.1v light-class carrier rocket from the Plesetsk space centre in northern Russia is planned for next year, a Russian space industry source told Sputnik. "The fifth and final launch of Soyuz-2.1v as part of flight tests is scheduled for 2019. Previously, it was planned to be carried out this year," the source said. Four previous test launches of the Soyuz-2.1v from Plesetsk were performed in the period from 2013 to 2018. Last year, a Soyuz-2.1v carrier rocket blasted off from the Plesetsk space centre with the Russian Defense Ministry's spacecraft on board. Source: Sputnik News
New Materials Architectures Sought to Cool Hypersonic Vehicles Washington DC (SPX) Dec 21, 2018 Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above - five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat. To address this thermal challenge, DARPA recently announced its Materials Architectures and Characterization for Hypersonics (MA ... read more
