Top 10 Things You Need To Know About Mars Landing on Thursday
1. NASA launched a mission back in 2017 called the Mars 2020 mission, which is due to arrive at Mars on Thursday 18th February 2021.
2. The Mars 2020 Mission is carrying two vehicles, the Perseverance Rover and the Ingenuity helicopter test-aircraft.
3. The Landing is scheduled for about 9pm UK time. The Spacecraft will smash into the Martian atmosphere at about 20:48UTC (8:48pm)
4. The Rover has an unusual landing sequence due to the thin atmosphere on Mars: First an ablative heat shield slows the spacecraft down from hypersonic, to supersonic speeds (thousands of miles per hour, down to hundreds). A supersonic parachute deploys to slow the spacecraft to tens of miles an hour before finally a sky-crane with retro-rockets hovers the rover about 20m above the surface. The Rover is lowered down to the ground on cables, underneath a hovering rocket, cut's itself loose and... we're down!
5. What happens to the sky-crane? That flies away to a safe distance before gracefully crashing into a near-by hill-side.
6. Perseverance is a NASA Jet Propulsion Laboratory (JPL) mission, primarily to drill deep into the rocks of Mars ready for a subsequent return flight for the samples all of the way back to Earth.
7. Ingenuity won't be the first aircraft to fly on another planet. Back in 1987 the USSR (modern day Russia) flew a high altitude balloon in the atmosphere of Venus. However, Ingenuity will be the first powered flight (think Wright brothers, vs hot air balloons) on another celestial body.
8. Perseverance was much cheaper than most Mars rovers to build because her design was based on the very visually similar Curiosity Rover which arrived at Mars' Gale Crater in 2012.
9. Perseverance is planning to land in Jezero Crater, a 49km crater which is believed was once an enormous lake.
10. The Mars 2020 spacecraft carries two microphones, which means that for the first time, we will be able to hear the sounds of entering the Martian atmosphere, and the sounds around Perserverance Rover as she explores the Martian landscape on arrival.
