The launch date is planned for August 2024. This will be the first Time to Use Blue Origin's New Glenn rocket, but since the contract is only worth $79 million, NASA is willing to take the risk.
The mission is called ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers).
Satellites weigh close half a ton each. The New Glenn, which is 320 feet tall and 23 feet in diameter, can lift a payload of 45 metric tons. Its first launch was planned four years ago.
Elon Musk has already made all the flights to Mars so far, but his last two rockets headed there exploded. He once called Bezos "a dilettante" when it came to space. Bezos will no doubt be hoping to prove him wrong.
