Here is a photo of #ClydeTombaugh having supper at @SHube3’s house, along with an email from @SHube3’s dad explaining the amazing story! It came to light as we are remembering that it was #OnThisDay 18 February 1930 that #CyldeTombaugh discovered #Pluto Thanks for sharing!

Three prominent features on the Kuiper Belt object #Arrokoth – the farthest planetary body ever explored, by NASA's New Horizons spacecraft – now have official names.jhuapl.link/gv5 NASA Solar System Johns Hopkins APL Southwest Research Institute

DART is on schedule to impact Didymos's moon, Dimorphos. Impact scheduled for 7:14pm EDT or 2314 GMT. DART's camera, DRACO, is the newer version of New Horizon's LORRI camera.

DART/DRACO can now resolve the blog that was the combo Didymos and Dimorphos. Wahooo!

Last DART poll taking place now. About 7000miles from Dimorphos. All systems reporting nominal.

Some background. DART (double asteroid redirection test) is NASA's first planetary protection mission. Basic idea is to test to see if an impact by a spacecraft can affect the orbit of an asteroid.

The target of the DART spacecraft is the moon (Dimorphos) of asteroid Didymos. The moon is about 1/5 the size of Didymos. Dimorphos takes about 11hrs 5min to orbit Didymos and the hope is that after the impact, a change in this orbital period will result.

Ground telescopes as well as some spacecraft will also be watching the impact.

On Sep 11, LICIA Cube was released from the DART spacecraft. It is to document/image the impact. LICIA Cube is from the Italian space agency

The one way light time from Earth to the DART spacecraft is on the order of 35 sec at impact. (11 million kilometers/6.8 million miles). Currently at 11 million miles from Dimorphos

Projected miss distance just reported as 17m.

Spectacular image

perfect target hit. No signal! Success!

So honored to receive the 2022 Resnik Challenger Medal from the Society of Women Engineers (SWE). It's humbling and exciting at the same time. Thank you SWE for continuing to support and inspire women engineers. SWE

Congratulations to Kerri Phillips and Alice Bowman on your SWE Emerging Leader and Resnik Challenger Medal Awards. Can't wait to celebrate with you at #we22 this week! #opportunity SWE jhuapl.edu/NewsStory/2210…

Alice Bowman shared her path to becoming a NASA mission operations manager. Every job, cashier, waitress, researcher, taught her something that prepared her for what she does today.
