A rocket carrying a small, Maine-made satellite had to scrub its launch Monday night. Another attempt will take place just after midnight on Wednesday, July 3.

The Firefly Aerospace rocket will launch from Vandenberg Space Force Base in California. 

Technicians aborted Monday’s launch seconds before liftoff due to “a faulty ground support equipment connection that has been fixed,” Firefly posted on X, formerly known as Twitter.

Firefly is working under contract with NASA.

The rocket is carrying a payload of small satellites, including MESAT1, a satellite designed and built by the University of Maine’s space initiative.

Described as “Maine’s first research satellite,” it will collect climate data from Earth’s upper atmosphere, according to the university.

The nanosatellite appears in photographs to be small enough to fit in a backpack. 

It uses four cameras to measure water and energy in the atmosphere, according to the university.
