Spaceport America — Nasa launched and tested a new umbrella-like heat shield on Wednesday, opening the door to landing humans on Mars.

The new technology — dubbed the adaptable deployable entry placement technology (ADEPT) — can be stored like a folded umbrella inside smaller rockets, opening handle-up in space to protect larger payloads as they enter a planet’s atmosphere, said Brandon Smith, Nasa’s principal investigator on the project. The shape allows it to protect larger areas than current heat shields.

"At the larger scales, it could be used for something as grand as human Mars explorations, or potentially human cargo landings on Mars," Smith told Reuters at the Spaceport America launch site, about 80km north of Las Cruces, New Mexico.

Nasa is preparing to send a new rover robotic lander to Mars in 2020 and plans to send human astronauts in 2033. The rover will search for previous signs on life on Mars and demonstrate technology that could helpast ronauts survive there. The goal of sending humans to Mars was set in 2010 during the administration of president Barack Obama and was affirmed by US President Donald Trump last December.

Before Nasa can send humans to Mars, it will need to land a lot of cargo there and the new heat shield could help, if it works, Smith said. The system also could also be used with crew capsules, protecting astronauts.

ADEPT, launched with a SpaceLoft sub-orbital rocket made by UP Aerospace, was tested at the spaceport in southern New Mexico. It deployed between 100km and 120km before opening and making its way back to Earth, landing at White Sands Missile Range.

Data gathered from the test will not be available until the shield is recovered, officials said. The system, once implemented, will allow Nasa to send more complex missions to other planets.

"Typically, heat shields are rigid structures, but this one can actually deploy in space," Smith said. "What that allows you to do is to get around the volume constraints of a typical launch vehicle that are long and slender." He added that the new heat shield can also be used to run recoverable experiments in Earth’s upper atmosphere and send probes to Venus.
