NASA to crash a spacecraft into asteroid around 7:15 PM this evening.
From NASA:
"Watch as NASA’s DART Mission Attempts the World’s First-Ever Test of Planetary Defense Description: Countdown to impact as NASA’s Double Asteroid Redirection Test (DART) attempts humanity’s first-ever test of planetary defense! The DART spacecraft will intentionally crash into asteroid Dimorphos at 7:14 p.m. ET on Monday, September 26, 2022 to see if kinetic force can change its orbit. Why? If this test is successful, the same technique could be used to deflect an Earth-threatening asteroid in the future, should one ever be discovered. DART’s target asteroid is NOT a threat to Earth before, during or after the impact event."
Live coverage from NASA beginning at 6:00 PM EST this evening

Hey!!! it worked!!!!........uh, Houston, we have a slight problem.....

I love this movie and Steve Buscemi! "Define irony. Bunch of idiots dancing on a plane to a song made famous by a band that died in a plane crash"
Different movie, but several good quotes. Hey doing my best to hi-jack this thread!!

mot sure hi-jacking this thread would be irony or not ?

Success!! I watched most of the rebroadcast. Amazing! I love how happy and excited the crew was.

haha
I was going to play a tune while we waited guess it hit already
well I'll play the tune anyway

Pretty classy fender bender, good that they hit where it was supposed to.

I wonder when we will find out if this little crash was a success.
I also wonder how much it cost us.

I wonder when we will find out if this little crash was a success. I also wonder how much it cost us. Thanks RickB . What I really want to know is if it was knocked out of it's orbit, which was the actual goal of this expensive experiment I believe. Glad they hit the dang thing at least, but was it really successful? ETA: From NASA.gov: The investigation team will now observe Dimorphos using ground-based telescopes to confirm that DART’s impact altered the asteroid’s orbit around Didymos. Researchers expect the impact to shorten Dimorphos’ orbit by about 1%, or roughly 10 minutes; precisely measuring how much the asteroid was deflected is one of the primary purposes of the full-scale test. So we must wait for the answer.

I didn’t hear mention of this little Italian job during the short time I watched the impact. Along with the DART team, another set of JPL navigators is calculating and planning the trajectory of DART’s spacecraft companion: The Italian Space Agency’s (ASI) Light Italian CubeSat for Imaging Asteroids, or LICIACube, which has the important task of imaging DART’s impact effects on Dimorphos. The toaster-size spacecraft disconnected from DART on Sept. 11 to navigate interplanetary space on its own – with an assist from the team at JPL.
“We are working with ASI to get LICIACube to within 25 to 50 miles (40 to 80 kilometers) of Dimorphos just two to three minutes after DART’s impact – close enough to get good images of the impact and ejecta plume, but not so close LICIACube could be hit by ejecta,” said JPL’s LICIACube navigation lead Dan Lubey.
While not necessary for the DART mission to succeed, the pre- and post-impact images this small satellite’s two optical cameras LEIA (LICIACube Explorer Imaging for Asteroid) and LUKE (LICIACube Unit Key Explorer) will provide could benefit the scientific community for studies of near-Earth objects and aid in the interpretation of the DART results.

DART also had a passenger – a small spacecraft contributed by the Italian Space Agency (ASI). The shoebox-sized LICIACube (Light Italian CubeSat for Imaging of Asteroids) split apart from DART several days before DART’s impact with the moonlet. LICIACube was designed to capture images of the impact and material (ejecta) kicked up from the moonlet. Images from LICIACube were expected to be beamed back to Earth several hours after DART's impact.

or Because LICIACube doesn’t carry a large antenna, images will be downlinked to Earth one by one in the coming weeks.

It was discussed at the end of the video after the impact. Pretty cool.
