Space Probe Zooms Past Mars at 12,000 mph for Cosmic Slingshot!

NASA just sent a spacecraft called Psyche zooming past Mars at super-fast speeds to get a gravitational boost [a push from Mars's gravity] to help it travel to a mysterious metal asteroid. As it flies by, the spacecraft will take amazing pictures of Mars and test its instruments [tools for measuring things]. It's like using Mars as a springboard to launch into space!
