Nasa’s Perseverance rover is bearing down on Mars
IslamNews – The US space agency’s Perseverance rover is now just three weeks from arriving at Mars.
The robot’s current distance to the Red Planet is still some 4.5 million km (3 million miles), but that gap is closing at a rapid rate.
The biggest, most sophisticated vehicle ever sent to land on another planet, the Nasa robot is being targeted at a near-equatorial crater called Jezero.
Touchdown is expected shortly before 2100 GMT on Thursday 18 February.
To get down, the Nasa rover will have to survive what engineers call the “seven minutes of terror” – the time it takes to get from the top of the atmosphere to the surface.
The “terror” is a reference to the daunting challenge that is inherent in trying to reduce an entry speed of 20,000km/h to something like walking pace at the moment of “wheels down”.
