SpaceX’s Falcon 9 is scheduled to launch at approximately 1:11 AM EST, and will not only have Firefly Aerospace’s Blue Ghost 1 lander on board, but also the Resilience lander from the Japanese robotic spacecraft firm iSpace. It will take 45 days for the craft to journey to the Moon before it spends another 14 days carrying out surface operations. There’s no word on whether we’ll be able to watch it take off.

The Firefly lander will carry 10 NASA payloads to the surface. They’re designed to measure various particulate compositions, thermal properties, and electromagnetic activity of both the Moon and the Earth. It’ll collect data for various applications, from improving landing and takeoff procedures to learning about the Moon’s resources and its history.

The so-called LEXI payload is particularly interesting — it’s an x-ray machine that can read the Earth’s magnetic field. NASA will use the data to see how our magnetosphere interacts with solar winds, which could ultimately help accurately detect and track solar weather patterns that cause power outages on Earth and interfere with satellite and GPS systems.

This would be NASA’s second attempt to deploy such technology. It first launched the device, then known as STORM, into space in 2012. That one didn’t land on the moon, however, and wasn’t able to get the full picture that LEXI’s wide-angle sensors will be able to capture.
