NASA has launched one of its most crucial science missions to date, the Mars 2020 mission that carries its Perseverance robotic rover. This rover, a successor to the Curiosity robotic explorer, is equipped with sensors specifically designed to help it hopefully fund evidence of ancient, microbiotic life on Mars.

Mars 2020 departed from Cape Canaveral in Florida at 7:50 AM EDT (4:50 PM PDT). Perseverance was loaded atop a United Launch Alliance (ULA) Atlas V rocket, which had a good liftoff and deployed its second stage which put the spacecraft into a parking orbit as it readies to depart on its trip towards Mars, which will see it arrive in February 2021.
