+== NASA will try its Artemis II launch again in early April ==
+The agency anticipates about four launch opportunities between April 1 and 6.

+NASA will soon give it another go on April Fools' Day. On Thursday, NASA said it's targeting April 1 at 6:24 PM ET for the Artemis II mission's next launch attempt.
+In case that date doesn't pan out, NASA added April 2 at 7:22 PM as a secondary launch opportunity. If necessary, the agency foresees several more openings between April 1 and 6 to get the Orion rocket into space. "Within those six days between the first and the sixth, we can't always turn around every day for an attempt," NASA acting associate administrator Lori Glaze said at a press conference. "We would anticipate […] about four opportunities within that six-day period."
+In preparation, NASA is targeting March 19 (a week from today) to roll Artemis II back out to the launch pad. However, it warned that further setbacks could occur. "While I am comfortable and the agency is comfortable with targeting April 1 as our first opportunity, just keep in mind we still have work to go," Glaze said. "There are still things that need to be done within the [Vehicle Assembly Building] and out at the pad. As always, we'll be guided by what the hardware is telling us, and we will launch when we're ready."

+== NASA’s DART spacecraft changed an asteroid’s orbit around the sun ==
+Studying this asteroid could help protect Earth from future asteroid strikes

+A spacecraft slowed the orbit of a pair of asteroids around the sun by more than 10 micrometers per second — the first time human activity has altered the orbit of a celestial object, researchers report March 6 in Science Advances. The experiment could have implications for protecting Earth from future asteroid strikes.
+NASA’s Double Asteroid Redirection Test, or DART, intentionally crashed a spacecraft into the small asteroid Dimorphos in 2022. The goal was to change Dimorphos’ orbit around its larger sibling, Didymos. Within a month, researchers showed that the impact shortened Dimorphos’ 12-hour orbit by 32 minutes.
