Science Missions

Peering into the creation of the universe and traversing Mars

The James Webb Space Telescope is an orbiting infrared observatory that will look to the beginning of time and to hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today.

Much closer to home, NASA has sent five robotic vehicles, called rovers, to Mars. Rovers help scientists in their quest to understand what different parts of the planet are made of.

Semi-opaque layers of blue and gray gas and dust start at the bottom right and go toward the top left. The left pillar is the largest and widest. The peaks of the 2nd and 3rd pillars are set off in darker shades of blue outlines.
NASA’s James Webb Space Telescope’s mid-infrared view of the Pillars of Creation strikes a chilling tone. Thousands of stars that exist in this region seem to disappear, since stars typically do not emit much mid-infrared light, and seemingly endless layers of gas and dust become the centerpiece. The detection of dust by Webb’s Mid-Infrared Instrument (MIRI) is extremely important – dust is a major ingredient for star formation.

Decades of Discovery

NASA's first high profile program was Project Mercury, an effort to learn if humans could survive in space. 

NASA is responsible for unique scientific and technological achievements in human spaceflight, aeronautics, space science, and space applications that have had widespread impacts on our nation and the world. When NASA opened for business on October 1, 1958, it accelerated the work already started on human and robotic spaceflight.
