NASA's Three-Billion-Mile Journey to Pluto Reaches Historic Encounter

Source: NASA

NASA's New Horizons spacecraft is at Pluto.

After a decade-long journey through our solar system, New Horizons made its closest approach to Pluto Tuesday, about 7,750 miles above the surface -- roughly the same distance from New York to Mumbai, India - making it the first-ever space mission to explore a world so far from Earth.

"I'm delighted at this latest accomplishment by NASA, another first that demonstrates once again how the United States leads the world in space," said John Holdren, assistant to the President for Science and Technology and director of the White House Office of Science and Technology Policy. "New Horizons is the latest in a long line of scientific accomplishments at NASA, including multiple missions orbiting and exploring the surface of Mars in advance of human visits still to come; the remarkable Kepler mission to identify Earth-like planets around stars other than our own; and the DSCOVR satellite that soon will be beaming back images of the whole Earth in near real-time from a vantage point a million miles away. As New Horizons completes its flyby of Pluto and continues deeper into the Kuiper Belt, NASA's multifaceted journey of discovery continues."

"The exploration of Pluto and its moons by New Horizons represents the capstone event to 50 years of planetary exploration by NASA and the United States," said NASA Administrator Charles Bolden. "Once again we have achieved a historic first. The United States is the first nation to reach Pluto, and with this mission has completed the initial survey of our solar system, a remarkable accomplishment that no other nation can match."

Per the plan, the spacecraft currently is in data-gathering mode and not in contact with flight controllers at the Johns Hopkins University Applied Physical Laboratory (APL) in Laurel, Maryland. Scientists are waiting to find out whether New Horizons "phones home," transmitting to Earth a series of status updates that indicate the spacecraft survived the flyby and is in good health. The "call" is expected shortly after 9 p.m. tonight.

The Pluto story began only a generation ago when young Clyde Tombaugh was tasked to look for Planet X, theorized to exist beyond the orbit of Neptune. He discovered a faint point of light that we now see as a complex and fascinating world.

"Pluto was discovered just 85 years ago by a farmer's son from Kansas, inspired by a visionary from Boston, using a telescope in Flagstaff, Arizona," said John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington. "Today, science takes a great leap observing the Pluto system up close and flying into a new frontier that will help us better understand the origins of the solar system."

New Horizons' flyby of the dwarf planet and its five known moons is providing an up-close introduction to the solar system's Kuiper Belt, an outer region populated by icy objects ranging in size from boulders to dwarf planets. Kuiper Belt objects, such as Pluto, preserve evidence about the early formation of the solar system.

New Horizons principal investigator Alan Stern of the Southwest Research Institute (SwRI) in Boulder, Colorado, says the mission now is writing the textbook on Pluto.

"The New Horizons team is proud to have accomplished the first exploration of the Pluto system," Stern said. "This mission has inspired people across the world with the excitement of exploration and what humankind can achieve."

New Horizons' almost 10-year, three-billion-mile journey to closest approach at Pluto took about one minute less than predicted when the craft was launched in January 2006. The spacecraft threaded the needle through a 36-by-57 mile (60 by 90 kilometers) window in space -- the equivalent of a commercial airliner arriving no more off target than the width of a tennis ball.

Because New Horizons is the fastest spacecraft ever launched - hurtling through the Pluto system at more than 30,000 mph, a collision with a particle as small as a grain of rice could incapacitate the spacecraft. Once it reestablishes contact Tuesday night, it will take 16 months for New Horizons to send its cache of data - 10 years' worth -- back to Earth.

New Horizons is the latest in a long line of scientific accomplishments at NASA, including multiple rovers exploring the surface of Mars, the Cassini spacecraft that has revolutionized our understanding of Saturn and the Hubble Space Telescope, which recently celebrated its 25th anniversary. All of this scientific research and discovery is helping to inform the agency's plan to send American astronauts to Mars in the 2030's.

"After nearly 15 years of planning, building, and flying the New Horizons spacecraft across the solar system, we've reached our goal," said project manager Glen Fountain at APL "The bounty of what we've collected is about to unfold."

APL designed, built and operates the New Horizons spacecraft and manages the mission for NASA's Science Mission Directorate. SwRI leads the mission, science team, payload operations and encounter science planning. New Horizons is part of NASA's New Frontiers Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama.

That the program wasn't killed by Republis and the funds not redirected towards war profiteering or raiding of the national treasury.

Glad we're able to bear the fruits of a history scientific mission, one that somehow slipped under their cynical anti-science anti-NASA radar.

I've still never quite gotten over Pluto's demotion, sigh. http://www.vox.com/2015/4/16/8420813/pluto-not-a-planet

Apparently, Pluto IS bigger than some thought.

Fresh measurements from New Horizons, the first spacecraft to reach Pluto on the outer edge of the solar system, show that it is 2,370 kilometres across, roughly two-thirds the size of Earth’s moon.

Alan Stern, the lead scientist on the $700m (£450m) mission, said the increased dimensions meant Pluto must hold more ice and less rock beneath its surface than researchers had expected. Pluto has been hard to measure with any accuracy from Earth because it is so far away, and its atmosphere creates mirages that can fool ground-based telescopes.

Other instruments onboard New Horizons confirmed that Pluto’s north pole bears an icy cap. The latest measurements beamed to Earth from the probe picked up chemical signatures of methane and nitrogen ice in the polar cap.

... but what's with the strong political and nationalistic jingoism from NASA Administrator Charles Bolden? We spent all that money just to be "first"? So is this the "race to the moon" just to beat the Russians all over again? Are you kidding me? I'm sick of it.

...has been abysmal, except for the basics--getting the photos and science info out. The "P.R. Show" early this morning was embarassing, with the tiny US flags and the maudlin comments. I hope that more media savvy people are in charge tonight for the crucial "phone home" from New Horizons. It's only 10 minutes away and what does NASA have on its TV channel--a vid from their "files"--a truly boring, very old astronaut talking about the Russian-US cooperation on the space station. That might be interesting IN ANY OTHER CONTEXT BUT THIS ONE! Gawd. I can't find confirmation of the time--of the "phone home" or the media briefing. I can't find out what site to go to at 5:30 PDT. ("Phone home" is supposed to occur at 5:53.) Etc.

Well, we'll see. It's supposed to be here, in a couple of minutes:

...the audience wouldn't cooperate (hah, hah, hah). (One of their "presenters" tried to rev up a "USA! USA!" chant, and nobody picked it up.)

They started with critically important press conference with an irrelevant congrats message from Stephen Hawking. (If New Horizons doesn't phone home, does Hawking take it back?) Mood in some palatial room that Hawking is inhabiting. Mood. Then a very emotional SONG, with old vid and animation! This just sucks.

Flags will be next.

NASA was much better at PR when the PR was run by engineers, who stuck to THE FACTS, and whose eruptions of enthusiasm were RARE and GENUINE.

This is too...packaged?

The actual "phone home" was exciting because I think it was real--the actual telemetry reports to Operations Manager Alice Bowman ("Mom&quot , station by station, reporting "nominal," I guessed meaning okay.

How much better would it have been if the "presenters" (Mike Buckley, Duane Brown) had explained each of these reporting stations, which were mostly identified by acronym as it happened! I mostly couldn't tell which systems were reporting. And if the "presenters" should have explained what "nominal" was going to mean (at first I thought it meant "minimal," i.e., minimal power, minimal propulsion, etc.). "Nominal" actually meant "optimal" (a guess, or at least okay). Why didn't they explain this ahead of time, instead of all this emotional garbage?

I don't want to downplay the brilliance and persistence of this amazing science team. I am flabbergasted by what they've been able to do, and I think it's very, VERY important work. But at the crucial media moments, some evil corporate mind has taken over--an evil mind that tries to lure you with emotional music to buy shit you don't need or worse, is really bad for you--and then it adds U.S. flags in the ultimate hypocrisy.

We see this sickly combo--emotionalism and flag-waving--on TV commercials all the time, and hear it on the radio.

It. Is. Not. Science. It is the opposite of wonder.

Yup, out came the flags--not in the stupid proliferation of early this morning, with everybody in the control room wiggling a little flag. Just a couple of important people had the flags.

The "presenters" are "feel good" guys, who want to know how it FEELS. How does it FEEL?, they ask, over and over again, of different scientists. How did that feel? What are you feeling now?

The accomplishment is momentous. The P.R. sucks.

The U.S. flag again. OMG.

WHY DIDN'T THEY HAVE THE WORLD FLAG, MADE FROM THE APOLLO MISSION CAMERA LOOKING BACK AT EARTH?

Or at least both flags--us and all humanity. NASA's chief Charlie Bolden mentioned all those other humans but his flag-waving and all the flag waving is really small-minded, in such ironic contrast to the mission itself.

I've been searching sites to get these times, and I'm pretty sure this is correct. But maybe the time-line for release of info has been pushed forward. What I'm worried about is that you and others will tune in at 8 pm and it'll all be over.

Well, this won't be over for months and years, as they download the flyby data, and obtain and download new data in the Kuiper Belt. But I mean the dramatic re-connection with the spacecraft which has been silent for the hours of the flyby. They won't know for sure it made it thru the closest approach until it signals back to earth. That's the approx. 5:30 time PDT. Then NASA will speak at 6:30 pm PDT.

Please correct me if you know for sure I'm wrong. Here's what where I got my times:

http://www.businessinsider.com/how-to-watch-new-horizons-pluto-flyby-2015-7

I think you didn't notice that the 8:30 pm time you may have read is EASTERN time. Those in the west need to subtract 3 hours from that. New Horizons will phone home just after 5:30 PACIFIC DAYLIGHT TIME. (To be exact, 5:53 pm PDT, some sites say.)

That is according to several sites that I searched. I believe that the "phone home" will be live at NASA and other sites, and probably on some TV channels. After that, NASA is doing a media briefing, live, at 6:30 pm PACIFIC time.

It's vital that New Horizons sends this 5:30-ish pm PDT signal back to Earth, or all the flyby data and future data could be lost. It has been on its own since early this morning, doing numerous experiments and taking numerous, very high resolution pictures (much higher resolution than we've seen, even just yesterday). It couldn't do all this and broadcast home at the same time. It will have taken 4.5 hours from Pluto to Earth for the signal to reach us that all is okay aboard the spacecraft. That signal will likely come at 5:53 pm PACIFIC time, but to be safe, tune in at 5:30.
