Space missions dispatched into the solar system often have journeys lasting years before reaching a scientific payoff, but NASA’s Parker Solar Probe launched last weekend on a speedy departure from planet Earth is already getting ready to sweep closer to the sun than any spacecraft in history during a flyby later this year.

Boeing officials said Monday the company’s Starliner crew capsule will fly a second time without astronauts after software problems and other issues plagued a first test flight in December, preventing the ship from reaching the International Space Station.

A barge and command ship chartered by SpaceX are stationed in the Atlantic Ocean off Florida’s East Coast in a bid to recover a used-up Falcon 9 rocket stage Tuesday in a long-theorized — but never tried — maneuver that could lay the groundwork for a big advance in space technology.
