SpaceX loses contact with Starship rocket eight minutes after second launch

SpaceX launched its massive Starship rocket in Texas, US, but lost contact after eight minutes of flight. The top part of the rocket - the most powerful ever developed - successfully separated from the booster which then blew up. Contact was then lost with the main rocket. Elon Musk's company still hailed it as a success and the rocket flew further than the failed first attempt in April.
