This color picture is made from images taken by the imaging system on the Galileo spacecraft about 14 minutes before its closest approach to asteroid 243 Ida on August 28, 1993. The range from the spacecraft was about 10,500 kilometers (6,500 miles). The images used are from the sequence in which Ida's moon was originally discovered; the moon is visible to the right of the asteroid. This picture is made from images through the 4100-angstrom (violet), 7560 A (infrared) and 9680 A (infrared) filters. The color is 'enhanced' in the sense that the CCD camera is sensitive to near infrared wavelengths of light beyond human vision; a 'natural' color picture of this asteroid would appear mostly gray.

John Houbolt, an engineer at Langley Research Center, is credited with fully developing the lunar-orbit rendezvous (LOR) approach. It involved firing three spacecraft (command module, service module, and lunar module) aboard one Saturn V rocket into Earth orbit. Once there, the last stage of the Saturn boosted the spacecraft on a lunar trajectory and eventually into orbit. Only the lunar module would go down to the surface. It would then return and redock with the orbiting command module in the top-half of the lunar module (leaving the lower-half on the moon). The astronauts would return to Earth in the command module while the remainder of the lunar module was ejected into space.

The towering 327-foot-tall Ares I-X rocket leaves the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The rocket, riding atop a crawler-transporter, headed down the 4.2-mile track to Launch Pad 39B. The move to the launch pad, known as "rollout," began at 1:39 a.m. EDT and ended with “hard down” at the launch pad at 9:17 a.m. EDT.

Astronomers used the Galaxy Evolution Explorer (GALEX) telescope to take this deep image in ultraviolet light of the sprawling spiral galaxy M81, hoping to learn where it kept its hot stars. Hot stars emit more ultraviolet than cool stars, and are frequently associated with young, open clusters of stars and energetic star-forming regions. Less than […]
