From Wiki:
New Horizons has both spin-stabilized (cruise) and three-axis stabilized (science) modes, controlled entirely with hydrazine monopropellant. Seventy-seven kilograms of hydrazine provides a delta-v capability of over 290 m/s after launch. Helium is used as a pressurant, with an elastomeric diaphragm assisting expulsion. The spacecraft's on-orbit mass including fuel will be over 470 kg for a Jupiter flyby trajectory, but would have been only 445 kg for a direct flight to Pluto. This would have meant less fuel for later Kuiper Belt operations and is caused by the launch vehicle performance limitations for a direct-to-Pluto flight. There are 16 thrusters on New Horizons: four 1 lbf (4.4 N) and twelve 0.2 lbf (0.9 N) plumbed into redundant branches. The larger thrusters are used primarily for trajectory corrections, and the small ones (previously used on Cassini and the Voyager spacecraft) are used primarily for attitude control and spinup/spindown maneuvers. Two star cameras (from Galileo Avionica) are used for fine attitude control. They are mounted on the face of the spacecraft and provide attitude information while in spinning or in 3-axis mode. Between star camera readings, knowledge is provided by dual redundant Miniature Inertial Measurement Unit (MIMU) from Honeywell. Each unit contains three solid-state gyroscopes and three accelerometers. Two Adcole Sun sensors provide coarse attitude control. One detects angle to the Sun, while the other measures spin rate and clocking.
The New Horizons spacecraft. It will reach Pluto July 14th 2015.
The New Horizons spacecraft is currently over halfway to Pluto, and set to arrive in 2015.
A small amount of the ashes of American astronomer Clyde Tombaugh are on board the New Horizons spacecraft. As of 2017, the spacecraft is en route to Kuiper belt object (486958) 2014 MU69.
Not yet, but the "New Horizons" space craft was launched in January 2006. It is expected to reach Pluto some time in 2015 if nothing goes wrong.
No robots or satellites have ever explored Pluto. But one spacecraft did do a flyby.On July 14, 2015, the New Horizons spacecraft flew 12,500 km (7,800 mi) above the surface of Pluto, making it the first spacecraft to explore the dwarf planet.On October 25, 2016, the last of the recorded data from the Pluto flyby was received from New Horizons.
The name of the spacecraft is, rather anticlimactically, "New Horizons".

They sent the New Horizons spacecraft, with no humans on board.
No spacecraft has ever landed on Pluto. The New Horizons spacecraft did a flyby (2015-2016) but did not land on the surface.
The New Horizons spacecraft, which completed its Pluto flyby in 2016.
It's not a shuttle. The spacecraft New Horizons is on its way to Pluto.
None. The New Horizons spacecraft only observed Pluto from orbit.
The ashes of Clyde Tombaugh, the astronomer who discovered Pluto in 1930, are aboard the New Horizons spacecraft. After his death in 1997, a small container with his ashes was attached to the spacecraft as a way to honor his role in the exploration of the distant dwarf planet.
