NASA and United Launch Alliance have delayed blast-off for the Mars 2020 mission from July 22nd to “no earlier than” July 30th.

NASA had pushed back the Mars 2020 takeoff from its original July 17th date to the 22nd after a problem with encapsulating the spacecraft.

NASA has been developing Perseverance and the Mars 2020 mission for years, and many pieces need to come together for the expedition to be a success.
