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.
The flights would not begin until research into production and maintenance of these bubbles is completed, which the authors estimate would require a minimum of 10–15 years. After that, the space shield may be large enough by 2050 to prevent crossing of the 2 °C (3.6 °F) threshold. [21] [20] [22]
