Someone please help NASA come up with a better name for New Horizonsí next space target

Now, you can suggest nicknames on a website hosted by the SETI Institute of Mountain View, California. But donít worry, this wonít turn into another Boaty McBoatface situation. Members of the public can nominate names, and then officials will select their favorite submissions and put them up for vote. People can also check to see which names are getting the most love over the next month.

As it looks like it is probably a binary, Eric Berger has nominated "Carolyn & Eugene", which I think would be a fitting tribute to their immense contribution.

Marc Buie, in New Horizons briefing at #AGU17: think MU69 is a contact binary, with a small moon orbiting it that was seen in SOFIA occultation but not in later Argentina observations.

I'm glad 'Horizons' next target is proving to be more interesting than expected.

Assuming the moonlet is confirmed at in indeed orbits between 200-300 km from MU69, would the 3500 km planned for the flyby still be sufficiently safe?

New Horizons Corrects Its Course in the Kuiper Belt

NASA's New Horizons spacecraft carried out a short, 2.5-minute engine burn on Saturday, Dec. 9 that refined its course toward 2014 MU69, the ancient Kuiper Belt object it will fly by a little more than a year from now.

Setting a record for the farthest spacecraft course correction to date, the engine burn also adjusted the arrival time at MU69 to optimize flyby science.

Telemetry confirming that the maneuver went as planned reached the New Horizons mission operations center around 1 p.m. EST at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, via NASA's Deep Space Network (DSN) stations in Goldstone, California. The radio signals carrying the data traveled over 3.8 billion miles (6.1 billion kilometers) and took five hours and 41 minutes to reach Earth at the speed of light.

Operating by timed commands stored on its computer, New Horizons fired its thrusters for 152 seconds, adjusting its velocity by about 151 centimeters per second, a little more than three miles per hour. The maneuver both refined the course toward and optimized the flyby arrival time at MU69, by setting closest approach to 12:33 a.m. EST (5:33 UTC) on Jan. 1, 2019. The prime flyby distance is set at 2,175 miles (3,500 kilometers); the timing provides better visibility for DSN's powerful antennas to reflect radar waves off the surface of MU69 for New Horizons to receive Ė a difficult experiment that, if it succeeds, will help scientists determine the reflectivity and roughness of MU69's surface.

Today's maneuver was the last trajectory correction during the spacecraft's long "cruise" between Pluto, which it flew past in July 2015, and the MU69 flyby. New Horizons Mission Design Lead Yanping Guo, of APL, said the next course-correction opportunity comes in October 2018, at the start of the MU69 approach phase. The mission team is using data from NASA's Hubble Space Telescope and the European Space Agency's Gaia mission to hone its aim toward MU69, which was discovered in 2014.

"We are on course and getting more excited all the time; this flyby is now barely a year away!" said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute, Boulder, Colorado.

The mission team will put the New Horizons spacecraft into hibernation mode on Dec. 21, where it will stay until early next June. The spacecraft is healthy and speeding away from the Sun at 31,786 miles (51,156 kilometers) per hour, or over 750,000 miles (1.2 million kilometers) per day.
