SPACEX LAUNCHES POLARIS DAWN, WHERE ASTRONAUTS WILL VENTURE FARTHER THAN ANY HUMANS IN MORE THAN 50 YEARS

Summary from the TLDR newsletter

The Polaris Dawn mission lifted off on a SpaceX Falcon 9 in the early hours of Tuesday morning. The mission will travel to the highest altitude humans have traveled since the Apollo 17 mission to the moon in 1972. The four-person crew will fly through the high-energy Van Allen belt and also attempt the first spacewalk not involving government astronauts. They will be testing new extravehicular activity suits designed by SpaceX. The mission is a partnership between tech billionaire Jared Isaacman and SpaceX - neither party has disclosed the cost of the flight.
