The New Horizons flyby of Pluto will (hopefully) reach its closest approach on July 14, 2015 at approximately 7:49 AM EDT (11:49 AM UT) - just hours from now.

And one article I stumbled across - Wired.com - New Horizonsí Finest Moment Could Be Its Hour of Destruction (posted July 13, 2015) - provides this remarkably exact time: "7:49:58 AM Eastern time"

And also says:

"With all sensors trained on Pluto, New Horizons wonít phone home for 21 straight hours."


Another link - New York Times - New Horizons' Pluto Flyby (July 14, 2015) - says in the last section of the animated slideshow near the top of the page:

"Confirmation that New Horizon survived the flyby is not expected until after 9:00 p.m., in part because signals from Pluto take four and a half hours to reach Earth."

Quoted from the last link:

"Pluto is 2,370 kilometers (1,473 miles) in diameter, give or take 20 kilometers. This makes it undisputedly larger than Eris, the second largest object in the Kuiper Belt at 2,336 kilometers with a potential error of +/- 12 kilometers, and ends a decade-long debate over which object is larger."


However, Eris still has more mass. Another recent link:

Quote:

"Itís worth noting that Pluto and Erisí masses have been precisely known for some time ó Eris is around one-third more massive than Pluto. By measuring the characteristics of moons orbiting both dwarf planets, an accurate mass can be calculated."

Addition, Aug. 9, 2015, 1:10 AM EDT: Quoted from this page from The Guardian:

"The New Horizons probe has made contact with Earth, proof that the spacecraft survived its historic flyby of Pluto.

The signal was received at precisely 8.52.37pm Eastern time."
