NEW HORIZONS EXPLORATION TARGET 2014 MU69 OCCULTS A STAR
On July 17, 2017 at 03:50 UTC, members of the New Horizons science team successfully observed Kuiper belt object 2014 MU69 passing in front of a background star in the constellation Sagittarius.
The 24 frames in this animation were separated by 0.2 seconds apiece. In each 0.2 seconds, the shadow of 2014 MU69 passed 4 kilometers across Earth's surface. Observations like these will allow the team to constrain the size and position of the New Horizons mission's flyby target, improving the precision of their encounter planning.
This animation has been processed from the originally published version to reduce noise and align the star field.
The New Horizons team enjoyed strong support from Argentinian scientists, government officials, and locals, who went above and beyond to ensure mission success.
“I’ve been calling the people who helped us, our ‘twelfth player,’” [team member Mark] Buie said. “The Comodoro Rivadavia community came together and did some amazing things for us.” A major national highway was closed for two hours to keep car headlights away. Street lights were turned off to ensure absolute darkness. People like the Intendente or Mayor of the Comodoro parked trucks as wind breaks. Said Buie, “The local people were a major team player.”
“Planning for this complex astronomical deployment started just a few months ago and although the odds seem daunting -- like finding a needle in a haystack -- the team succeeded, thanks to the help of institutions like CONAE (Argentina's National Commission on Space Activities), and all the goodwill of the Argentinian people. This is another example of how space exploration brings out the best in us,” said New Horizons Program Executive Adriana Ocampo.
