In public-key cryptography, the Station-to-Station (STS) protocol is a cryptographic key agreement scheme. The protocol is based on classic Diffie–Hellman , and provides mutual key and entity authentication .
Nuclear Ferry and Shuttle Orbiter docked to an Orbital Propellant Depot. The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), [1] was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program (NASA appropriated the name for its Space Shuttle Program, the only component of ...
STS-1 (Space Transportation System-1) was the first orbital spaceflight of NASA's Space Shuttle program. The first orbiter , Columbia , launched on April 12, 1981, [ 1 ] and returned on April 14, 1981, 54.5 hours later, having orbited the Earth 37 times.
Spacelab in orbit on STS-9. The Spacelab module was a European-funded pressurized laboratory that was carried within the payload bay and allowed for scientific research while in orbit. The Spacelab module contained two 2.7 m (9 ft) segments that were mounted in the aft end of the payload bay to maintain the center of gravity during flight.
Security token service (STS) is a cross-platform open standard core component of the OASIS group's WS-Trust web services single sign-on infrastructure framework specification. cf. [1] [2] Within that claims-based identity framework, a secure token service is responsible for issuing, validating, renewing and cancelling security tokens.
The codes were adopted from STS-41-B through STS-51-L (although the highest code used was actually STS-61-C), and the sequential numbers were used internally at NASA on all processing paperwork. After the Challenger disaster , NASA returned to using a sequential numbering system, with the number counting from the beginning of the STS program.
STS-9 (also referred to Spacelab 1) [1] was the ninth NASA Space Shuttle mission and the sixth mission of the Space Shuttle Columbia. Launched on November 28, 1983, the ten-day mission carried the first Spacelab laboratory module into orbit.
The flight was originally given the designation "2A.2", serving as a logistics flight to carry cargo to the then-uncrewed space station, in between 2A.1/STS-96 and 3A/STS-92. STS-101 was originally planned to arrive after the Service Module Zvezda , but when Zvezda fell further behind, mission 2A.2 was split into 2A.2a and 2A.2b, the former ...
