The Science Payload

The seven science instruments aboard the New Horizons spacecraft.

The New Horizons spacecraft carries a payload of seven scientific instruments. These instruments will allow NASA scientists to investigate the surface geology, composition, atmospheric pressure, and temperature of Pluto and its moons.

Technicians at Johns Hopkins University install the LORRI instrument into the New Horizons spacecraft.
The antennas on the New Horizons spacecraft receive commands from mission control and transmit data back to Earth from the seven scientific instruments.

The RTG or Radioisotope Thermoelectric Generator, provides electrical power for the spacecraft by converting the heat generated by the decay of plutonium-238 (Pu-238) fuel into electricity.

The Honeymooners in Outer Space

The Honeymooners featured Audrey Meadows as Alice Kramden and Jackie Gleason as Ralph Kramden.

Ralph and Alice are complementary optical instruments. They are named after Ralph and Alice Kramden, two of the major characters in an American comedy TV series from the 1950s called The Honeymooners.
