The key to a reusable shield against this type of heating is very low-density material, similar to how a thermos bottle inhibits convective heat transfer. [citation needed] Some high-temperature metal alloys can withstand reentry heat; they simply get hot and re-radiate the absorbed heat.
Polar Satellite Launch Vehicle – C39 was the forty-first flight of the PSLV series of launch vehicles on 31 August 2017. Launched in its XL configuration, the vehicle suffered a rare failure – the first failure after 24 years of operations [1] when the heat shield failed to separate and the payload became trapped inside the heat shield and could not be deployed.
NASA subsequently decided to switch the launch vehicle for the Orbiting Carbon Observatory's replacement, OCO-2, from a Taurus to a Delta II rocket. [15] On August 31, 2017, ISRO's IRNSS-1H satellite failed to deploy after the payload fairing of the rocket PSLV-C39 failed to separate. As a result of extra mass, the rocket could not reach the ...

STS 114 day before launch ESP-2 in launch configuration Shown here is the design of the LMC (Lightweight Multi-Purpose Experiment Support Structure Carrier), which was mounted in the rear of the Shuttle's cargo bay. Mounted on the LMC is the TPS Repair Box, which would have been used in case to repair the Thermal Protection System of the Space ...

Then localised heat is applied to the component to remove, with less heating required than from cold. Most frequently, a hot air (or hot gas) gun, with a nozzle of appropriate size and shape, is used to heat the component, with nearby components shielded from the heat if necessary, followed by removal with tweezers or a vacuum tool.
