There are two points in space where an elevator's docking port could maintain a stable, lunar-synchronous position: the Earth-Moon Lagrange points L 1 and L 2.The 0.055 eccentricity of the lunar orbit means that these points are not fixed relative to the lunar surface : the L 1 is 56,315 km +/- 3,183 km away from the Earth-facing side of the Moon (at the lunar equator) and L 2 is 62,851 km ...
The concept of a Tsiolkovsky tower combined with a classic space elevator cable (reaching above the level of GEO) has been suggested. [6] Other ideas use very tall compressive towers to reduce the demands on launch vehicles. [97] The vehicle is "elevated" up the tower, which may extend as high as above the atmosphere, and is launched from the ...
A wire cable was connected to the top and bottom of the razor blade and to both halves of the cover. The cable was routed through a pulley on the hammerhead crane at the top of the launch umbilical tower (LUT) down to a tube on the right side of the 360-foot (110 m) level of the LUT. The cable was connected to a cylindrical weight inside a tube.
Apollo 8, flown to the Moon's orbit without an LM, was considered a "C-prime" mission, but its success gave NASA the confidence to skip the "E" mission, which would have tested the full Apollo spacecraft in medium or high Earth orbit. Apollo 10, the dress rehearsal for the lunar landing, was to be the "F" mission.
Space Shuttle Discovery is carried by a Crawler-transporter, a launch tower is visible in the background. A service structure is a steel framework or tower that is built on a rocket launch pad to facilitate assembly and servicing. An umbilical tower also usually includes an elevator which allows maintenance and crew access. Immediately before ...
The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC) in Florida, designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V, the Space Shuttle and the Space Launch System, and stack them vertically onto one of three mobile launcher platforms used by NASA.

The Curiosity team invented the sky crane system by studying old Viking landing system—its engines are "an upgraded 'reinvention' of Viking’s throttleable engines"—and landing experience from previous rovers. [5] The sky crane works much like a helicopter, and the team even consulted with Sikorsky Skycrane helicopter engineers and pilots. [9]
