NASA launches the Mars 2020 mission from Cape Canaveral.
An Atlas V turned years of preparation into a trajectory, sending a new scientific mission toward Mars.
NASA’s Mars 2020 mission launched on an Atlas V rocket from Cape Canaveral Air Force Station. For a planetary mission, liftoff is both spectacle and handoff: Earth’s launch systems begin a journey that must continue far beyond them.
The name Mars 2020 sounds like a date stamp, but the mission stretches time in both directions. Years of design stand behind the launch, while travel, arrival, and scientific work wait ahead.
A planetary launch is a sequence of handoffs: rocket to trajectory, cruise to arrival, instruments to the teams waiting to read them. July 30 records the moment that sequence left the coast and became a journey.
