July 14
7:30 a.m. – Media Briefing: Arrival at Pluto, Inside the Pluto System and New Horizons’ Perilous Path (live on NASA TV)

At 7:49 a.m., the New Horizons spacecraft will make history as flies past Pluto, after a journey of more than nine years and 3 billion miles. For much of the day the New Horizons spacecraft will be out of communication with mission control as it gathers data on Pluto and its moons.

The moment of closest approach will be marked with a live NASA TV broadcast that includes a countdown, a discussion of images and data received thus far, and what’s expected next as New Horizons makes its way past Pluto and potentially dangerous debris. Follow the path of the spacecraft in real time with a visualization of the actual trajectory data, using NASA’s Eyes on Pluto.

9 a.m. – noon -- Interview Opportunities (no NASA TV coverage)
Informal group briefings and availability for one-on-one interviews. An updated schedule will be posted in the New Horizons Media Center.

Noon – 3 p.m. – Panel Discussions (no NASA TV coverage)
  • New Horizons mission overview and history
  • Pluto system discoveries on approach
  • Mariner 4 and Pluto: 50 years to the day

8 – 9:15 p.m. -- NASA TV program, Phone Home, broadcast from APL Mission Control

NASA TV will share the suspenseful moments of this historic event with the public and museums around the world. The New Horizons spacecraft will send a preprogrammed signal after the close approach. The mission team on Earth should receive the signal at about 9:02 p.m. When New Horizons “phones home,” there will be a celebration of its success and the anticipation of data to come over the days and months ahead.

9:15 – 10 p.m. -- Media Briefing: New Horizons Health and Mission Status (live on NASA TV)

Getting closer! I can imagine a good deal of math required to thread the needle. If their math is not exact the spacecraft will film outer space during the pass.

Just something to think about. These are the devices and what the do I will add my thoughts.


Alice: Ultraviolet imaging spectrometer; analyzes composition and structure of Pluto's atmosphere and looks for atmospheres around Charon and Kuiper Belt Objects (KBOs).

REX: (Radio Science EXperiment) Measures atmospheric composition and temperature; passive radiometer.

LORRI: (Long Range Reconnaissance Imager) telescopic camera; obtains encounter data at long distances, maps Pluto's farside and provides high resolution geologic data.
SWAP: (Solar Wind Around Pluto) Solar wind and plasma spectrometer; measures atmospheric "escape rate" and observes Pluto's interaction with solar wind.

PEPSSI: (Pluto Energetic Particle Spectrometer Science Investigation) Energetic particle spectrometer; measures the composition and density of plasma (ions) escaping from Pluto's atmosphere.

SDC: (Student Dust Counter) Built and operated by students; measures the space dust peppering New Horizons during its voyage across the solar system.

They will show some pics of Pluto. What may not be shown are a dwarf star and its planets which has a large dust trail around it, notice the devices. In some of my post the orbit was reveal to you also one post explained look into this part of heaven this fall. I was not aware of this probe to clock its arrival moreover the probe JUNO will see its exit of our solar system. Its not what they tell you but what they are doing in both these area's of heaven at the same orbit as the book of Ezekiel describes.

Here is a reshearch question why do the need a plasma spectrometer?

If you notice the time ticks get spaced closer apart after the fly by. This is because New Horizons will get a gravity assist as it flies by Pluto. The space craft will have to maneuver as it flies by the Pluto system. If the maneuvers are not precise all we will get is pictures from outer space.

06/28/2015 - Starting to see craters. It will be interesting to see when our velocity starts to increase as Pluto's gravity begins to give the spacecraft a gravity assist. The scientist are going to have to calculate the change of velocity to calculate the roll program as the spacecraft threads the eye of the Pluto system.

Heliocentric Velocity - 14.54 km/s
Velocity relative to Pluto - 13.8 km/s

Pluto almost looks like Star Wars, "The Death Star" at this distance! :)

Date--------- Velocity relative to Pluto
6/28/2015 - 13.80 km/s
6/29/2015 - 13.79 km/s
7/01/2015 - 13.78 km/s

Date--------- Heliocentric Velocity
6/28/2015 - 14.54 km/s (32,525 mph)
6/29/2015 - 14.535 km/s (32,513 mph)
7/01/2015 - 14.53 km/s (32,502 mph)

Notice that the spacecraft is slowing down by about 10mph a day. The escape velocity from planet earth is 11.2 km/s while the escape velocity from our sun is 42.1 km/s from the same position of earth and the sun. Because the New Horizons space probe is slowing down I assume it is because it is going slower than the escape velocity required to exit our solar system.

Voyager's speed was helped by gravity assist from the planets. It is still going roughly 35,000 miles and is a sure bet at that distance to escape the suns gravity and exit the solar system and head towards Alpha Centuri in about 40,000 years. New Horizon's is currently going 32,500 and probably will not get much of an assist from Pluto. They did speed New Horizons up a tad to help thread the needle of the Pluto system...

http://pluto.jhuapl.edu/News-Center/News-Article.php?page=20150630

"With just two weeks to go before its historic July 14 flight past Pluto, NASA’s New Horizons spacecraft tapped the accelerator late last night and tweaked its path toward the Pluto system.The 23-second thruster burst was the third and final planned targeting maneuver of New Horizons’ approach phase to Pluto; it was also the smallest of the nine course corrections since New Horizons launched in January 2006. It bumped the spacecraft’s velocity by just 27 centimeters per second – about one-half mile per hour – slightly adjusting its arrival time and position at a flyby close-approach target point approximately 7,750 miles (12,500 kilometers) above Pluto’s surface." - From article

Looks like a giant crater on Pluto.. Possibly a collision with Charon? Looks like the spacecraft is gaining in velocity as it nears Pluto.

However there is good news...

"I'm pleased that our mission team quickly identified the problem and assured the health of the spacecraft," said Jim Green, NASA's Director of Planetary Science. "Now - with Pluto in our sights - we're on the verge of returning to normal operations and going for the gold."

5 Days from Pluto!

No images due to the spacecraft anomaly. 0.5 AU from Pluto with no signs yet of gravity assist. The moon is 0.0025 AU from earth. So New Horizons is 200 times further away from Pluto than the earth is from the moon. Should have some images by tomorrow...
