Why are there so many attempts to get to Mars right now?
Our Mars Perseverance Rover has successfully launched from Cape Canaveral, Florida.
It is after the Hope United Arab Emirate satellite was launched and China successfully launched its first rover mission on the Red Planet in recent weeks.
Summer 2020 is a popular time for missions on the red planet as the planets level out.
