Since the New Horizon probe has been given further orders to look at other lumps of rock/ice/whatever in the solar system (well we call it that but in all honesty the lumps could be from anywhere, and not always doing anything that is affected by the sun, with the exception of a weak gravitational pull and an even less EMR dose) , the people that are checkng the received imagery and other data might be in for a surprise sooner than later.
Binary is the best we have so far, what comes back New Year, at least the decyphering will be interesting, if they let the public into the secret.
Buie’s team has identified one more occultation opportunity, on Aug. 4, when telescopes could again be deployed to map 2014 MU69’s shape, and perhaps confirm the presence of a moon.
2014 MU69 will blot out the light from a star in a swath extending from South America, across the Atlantic Ocean, into North Africa. Buie said the New Horizons science team is discussing a field campaign with partners in Colombia and Senegal, where a network of mobile telescopes could be placed to try and find the shadow of 2014 MU69 and its potential moon.
After that, the next chance for scientists to learn more about 2014 MU69 will come in the final weeks and days before New Horizons speeds by the object.
“We won’t resolve the object until the week of the flyby, and it’s going to be a very exciting, almost overnight experience in which MU69 will go from a point of light to a real place in the sky, a new world that humans have explored,” Stern said.
Plot thickens as New Horizons moves within year of next flyby – Spaceflight Now
I'll probably start a MU69 thread in the next few days since this is going to be the biggest thing in planetary discovery before the end of the year.
