What began as a concept scribbled on a cocktail napkin in a Tucson bar 12 years ago — sending a spacecraft to an asteroid and retrieving a pristine sample to bring back to Earth for study — becomes reality Thursday with the launch of NASA’s OSIRIS-REx mission.

NASA has selected Blue Origin, Dynetics and SpaceX to move forward with development of human-rated lunar landers, committing nearly $1 billion in funding for a range of moonship concepts that include a variant of SpaceX’s next-generation Starship vehicle, officials announced Thursday.

The scheduled launch Saturday of two commercial BlackSky Earth-imaging satellites from New Zealand will double as an opportunity for Rocket Lab to test an enhanced heat shield on its Electron booster, an upgrade that should allow the company to recover rockets in better condition for eventual reuse.
