* December 2 – STS-61 is launched – This Space Shuttle mission to the Hubble Space Telescope (HST) installed corrective optics, plus upgrades, that not only allowed the telescope to focus properly, but also increased magnification/clarity beyond the original design: HST had been pre-designed for such future upgrades (see: continuous improvement). * February 13 – [...]

During early shuttle development there was great debate about the optimal shuttle design that best balanced capability, development cost and operating cost. Ultimately the current design was chosen, using a reusable winged orbiter, reusable solid rocket boosters, and an expendable external tank. The shuttle program was formally launched on January 5, 1972, when President Nixon [...]

It is located at the Kennedy Space Center Visitor Complex and is accessible by tourists. ”Explorer” is displayed alongside a gantry-style tower (which includes an elevator for accessibility) and visitors may view a mock-up payload, a [...]
Ultraviolet astronomy is generally used to refer to observations of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma ray astronomy. Light at these wavelengths is absorbed by the Earth’s atmosphere, so observations at these wavelengths must be performed from the upper atmosphere [...]

* September 29 – NASA resumes space shuttle flights, grounded after the Challenger disaster. * November 15 – In the Soviet Union, the uncrewed Shuttle ”Buran” is launched by an Energia rocket on her maiden orbital spaceflight (this was the first and last space flight for the shuttle). *Asteroid 3994 Ayashi is discovered by Masahiro [...]

Space Shuttle ”Atlantis” (Orbiter Vehicle Designation: OV-104) is a Space Shuttle orbiter belonging to the National Aeronautics and Space Administration (NASA), the spaceflight and space exploration agency of the United States (the other two surviving Space Shuttles are the ”Discovery” and the ”Endeavour”). The ”Atlantis” was the fourth operational (and the next-to-the-last) Space Shuttle to [...]

Individual Space Shuttle Orbiters are named in honor of antique sailing ships of the navies of the world, and they are also numbered using the NASA Orbiter Vehicle Designation system. While all of the Orbiters are externally practically identical, they have minor differences in their interiors. New equipment for the Orbiters is installed in the [...]
