SPACE: Stratolaunch abandons launch vehicle program. “Stratolaunch, the company founded by the late billionaire Paul Allen, said Jan. 18 that it is ending work on a launch vehicle that would be flown on the company’s giant aircraft. In a statement to SpaceNews, a company spokesman said that the company was ending work on its own family of launch vehicles and would instead use its aircraft for launching small Pegasus XL rockets from Northrop Grumman.”
