A rocket carrying NASA’s Perseverance Mars Rover took off from Cape Canaveral, Florida this week. The Mars Rover is once again on a mission to find signs of life on another planet. It’ll take seven months for the craft to get to Mars, where the Rover will be drilling for samples in an area called Jezero Crater. The crater is known by scientists to have once had water. And where there’s water, there may be— or may have been— life, possibly billions of years ago. For scientists at NASA, finding extraterrestrial life, “it’s really the holy grail” said NASA scientist Dr. Thomas Zurbuchen.
