Us developed inflatable spacecraft reducer for safe landing on Mars

According to the Star Spangled Banner of the United States, landing a large spacecraft safely on Mars is only one of the many engineering challenges faced by NASA to send humans into deep space. At the Langley Research Center in Hampton, Virginia, engineers are developing an inflatable speed reducer that looks like an oversized baby doughnut.
the report says that sending astronauts to Mars requires new technology, because the spacecraft that allows humans to land on Mars is larger than any spacecraft that has landed on other planets before. Engineers at Langley Research Center have been working on inflatable technology for 10 years and believe that this technology is close to practical application. Chetwood, an American expert, said the same inflatable technology could also be used to detect the atmospheres of other planets, such as Venus, Titan and Jupiter. A Chinese aerospace expert of

said that in addition to this technology, NASA also completed the first supersonic flight aerodynamic test of “low density supersonic reducer” (LDSD) in June 2014. So far, the maximum mass to land on the surface of Mars is the curiosity rover, which weighs about 1 ton. In order to send heavier probes to the surface of Mars and finally realize manned landing on Mars (more than 20 tons), the United States must develop deceleration technology that can quickly reduce the speed of large spacecraft in the thin Martian atmosphere. The test of

is the first of the three planned tests of NASA’s “low density supersonic reducer” project. Two more similar tests were conducted in 2015. If the “low density supersonic reducer” technology is mature, it can ensure that the United States can break through the current Mars landing quality limit as soon as possible. It is expected that NASA can fully master this technology in 2018, but from the perspective of demand, it may not have the opportunity to apply this technology until 2021.
