NASA's OSIRIS-REx asteroid probe is on the launch pad and poised for liftoff tonight on a United Launch Alliance Atlas V rocket assembled in Decatur, Ala. The launch window opens at 6:05 p.m. CDT. Watch the launch in the window below.

OSIRIS-REx is a name that stands for all of the probe's missions. Here they are as explained by principal scientist Dante Lauretta:

Origins – Return an asteroid sample for laboratory analysis. "This really is what drives our program. We're going to asteroid Bennu because it's a time capsule from the earliest stages of solar system formation, back when our planetary system was spread across as dust grains in a swirling cloud around our growing protostar."

Spectral Interpretation – Provide direct observations for telescopic data of the entire asteroid population.

Resource Identification – Map the chemistry and mineralogy of a primitive, carbon-rich asteroid.

Security – Measure the Yarkovsky effect, in which the asteroid absorbs the energy in sunlight, then emits that energy in the form of heat. "That causes a small thrust on the asteroid, changing its trajectory over time," Lauretta explained Tuesday. A better understanding of this phenomenon could not only help scientists know more about Bennu, but could be applied to asteroids throughout our solar system.

Regolith Explorer – Document the loose blanket of gravel and dirt on the surface, known as regolith.

This is a seven-year roundtrip mission. The probe will reach the near-Earth asteroid Bennu in 2018 and return with samples in 2023.
