Space Shuttle Discovery as it approaches the International Space Station during the STS-114 on 28 July 2005. The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the extreme 1,650 °C (3,000 °F) heat of atmospheric reentry. A secondary goal was to protect from the heat and cold of ...
LI-900 is a type of reusable surface insulation tile developed and manufactured by Lockheed Missiles and Space Company in Sunnyvale, California. It was designed for use on the Space Shuttle orbiter as part of its thermal protection system to minimize thermal conductivity while providing maximum thermal shock resistance.
Originally it was planned to have MISSE-1 and 2 deployed for about a year and MISSE-3 and 4 for up to three years. Due to the grounding of the shuttle fleet after the Space Shuttle Columbia disaster required that changes be made to these plans. MISSEs 1 and 2 provided the three-year data and MISSEs 3 and 4 have provided the one-year data.
The shuttle program was marked by triumphs and failures, including the 2003 Columbia disaster. The tragedies left a lasting mark on the perception of risks in space.
The positioning had to be precise. The shuttle's nose was raised 200 feet into the night sky so that the rudder could clear 80 feet of space. Endeavour was then turned 17 degrees clockwise to ...
Corrosion in space is the corrosion of materials occurring in outer space.Instead of moisture and oxygen acting as the primary corrosion causes, the materials exposed to outer space are subjected to vacuum, bombardment by ultraviolet and X-rays, solar energetic particles (mostly electrons and protons from solar wind), and electromagnetic radiation.

This new design introduced several other changes to improve resistance and give the device a longer shelf life, such as switching the material of the body from 17-4 PH steel to Inconel 718. [ 4 ] After the Apollo program ended, the Initiator was renamed and re-used on other spacecraft , such as the Space Shuttle .
Figure 1. An UHTC strake composed of three different sections with different UHTC compositions. [4]Beginning in the early 1960s, demand for high-temperature materials by the nascent aerospace industry prompted the United States Air Force Materials Laboratory to begin funding the development of a new class of materials that could withstand the environment of proposed hypersonic vehicles such as ...
