spacecraft ejected a smaller sensor drone spacecraft before crashing <br>
headlong into Dimorphos, the small 160 m satellite of a larger 780 m NEO <br>
named Didymous. The mission was a test to see if we could use a <br>
spacecraft impact to deflect the trajectory of an oncoming asteroid for <br>
obvious reasons.<br>
<br>
The mission succeeded in changing the orbit of Dimorphos around its <br>
primary Didymous by shortening its orbital period by 22 min, however in <br>
the process several boulders were dislodged that had three times the <br>
momentum of the spacecraft, thus changing the orbit in an unpredicted <br>
fashion.<br>
<br>
Still seems like progress to me. Here is the complete story from <br>
University of Maryland:<br>

<br>
Here is a link to the footage from the camera craft that got ejected <br>
prior to impact. The footage starts after the impact so in the beginning <br>
the target Dimorphos is hidden from view by the bright starburst pattern <br>
of ejecta. The large bright object to the right is the larger asteroid <br>
Didymous.<br>

Google also made a cute easter-egg that happens if you search for "DART <br>
mission".<br>
