CTOnews.com, Nov. 22 (Xinhua) when NASA's Artemis I mission returned to Earth around the moon a year ago, the Orion spacecraft traveled at more than 18000 mph, producing temperatures of 2700 degrees Fahrenheit, damaging the heat shield.
To this end, NASA is testing a new inflatable heat shield, from the existing test results, the results are satisfactory.
At present, the thermal insulation devices used by spacecraft are all hard materials, some of which can be disintegrated during the process of passing through the atmosphere of the probe object, and some can be stripped off after passing through the atmosphere. For example, after the American rover passes through the Martian atmosphere, the external thermal insulation protection device automatically disconnects.
However, the disadvantage of this kind of thermal insulation device is that its weight is too high, which limits the payload of the spacecraft. In addition, the volume of the thermal insulation is also limited because it must be able to be contained in the launch vehicle.
NASA tested the new heat shield in the low Earth orbit flight test of the inflatable Reducer (LOFTID). The test results show that the inflatable heat shield can not only slow down the spacecraft, but also withstand friction with the atmosphere to generate heat.
From the test results, this kind of inflatable heat shield has a broad application prospect. in the future, scientists can use it to send probes and other spacecraft to planets such as Mars, Venus and even Saturn, so that the heat shield does not rely on heavier materials. land on Earth or other planets.
CTOnews.com described the inflatable heat shield in detail in a press release. NASA attached a link here, and interested users can click on it to read more.
