"The launch readiness review is complete, and we are indeed go for launch," administrator Jim Bridenstine said.
"We are in extraordinary times right now with the coronavirus pandemic, and yet we have in fact persevered and we have protected this mission because it is so important."
The launch will take place at 7:50 am (1150 GMT) on Thursday from Cape Canaveral, Florida, on board a United Launch Alliance Atlas V rocket.
Live coverage will take place on YouTube and across social media platforms.
Following a seven-month journey,
Perseverance is set to land at Jezero Crater on February 18, 2021. The six-wheeled robot, which is about the size of an SUV and weighs 1,040 kilograms, is NASA's fifth Mars rover and its most advanced to date. It comes equipped with a small helicopter called
Ingenuity that will attempt to fly - a first on another planet - as well as a robotic arm, and an array of cameras and a pair of microphones.
To look for evidence of ancient fossilized bacteria, it will use two lasers and an X-ray capable of chemical analysis. It will gather rock and soil samples for a future mission that will bring them back to Earth.
