If successful, the 4-pound (1.8-kg) helicopter could lead to low-altitude aerial surveillance of distant worlds, officials said.The daredevil nature of the rover's descent to the Martian surface, at a site that NASA described as both tantalizing to scientists and especially hazardous for landing, was a momentous achievement in itself.The multi-stage spacecraft carrying the rover soared into the top of Martian atmosphere at nearly 16 times the speed of sound on Earth, angled to produce aerodynamic lift while jet thrusters adjusted its trajectory.A jarring, supersonic parachute inflation further slowed the descent, giving way to deployment of a rocket-powered "sky crane" vehicle that flew to a safe landing spot, lowered the rover on tethers, then flew off to crash a safe distance away.Perseverance's immediate predecessor, the rover Curiosity, landed in 2012 and remains in operation, as does the stationary lander InSight, which arrived in 2018 to study the deep interior of Mars.Last week, separate probes launched by the United Arab Emirates and China reached Martian orbit. NASA has three Mars satellites in orbit, along with two from the European Space Agency.FROM THE ARCHIVES<figure class='op-interactive'><iframe height='315' src='https://www.youtube.com/embed/UTAar03Sa2g?enablejsapi=1' width='560'></iframe></figure><div class='iwantbar'>Watch more in <a href='//www.iwantv.com.ph/'>iWantv</a> or <a href='//tfc.tv/'>TFC.tv</a></div>
