SPACEX POLARIS LAUNCH POSTPONED AFTER HELIUM LEAK IS DETECTED

Summary from the TLDR newsletter

SpaceX's Polaris Dawn mission has been delayed until later this week at the earliest due to a helium leak. The mission will send four private citizens (billionaire entrepreneur Jared Isaacman, retired Air Force Lt. Col. Scott “Kidd” Poteet, and SpaceX engineers Sarah Gillis and Anna Meno) to space on a mission that will include the first spacewalk carried out by a civilian crew. It was scheduled to lift off early Tuesday. Polaris Dawn is the first of three planned space flights funded and organized by Isaacman and SpaceX.
