Rehearsal Day
January 30, 2026
With just 36 hours to go before launch, all team members gather together to rehearse the multi-step process.
Launching a rocket, regardless of size, takes more than just one person pressing the "go" button. Carefully scripted to the minute, the PolarNOx rehearsal connected the research team in the science center with the NASA Wallops and the NASA Sounding Rocket Operations Contract (NSROC) team in the launchpad and communications centers.
The teams simulate, in real time, what is meant to happen during the real launch. Each system is checked for communication, telemetry, and control as much as possible. The script continues through the launch window; flight and experiment operations; and ends with the payload parachute deployment and landing.
Upon completing the rehearsal, all that's left is to wait for rocket launch call time.
The fully assembled rocket waits on the launchpad rail, boxed in with foam to protect the delicate instrumentation from the negative temperatures of Alaska.
Watching over the research team members are numerous good luck photos, each with a special significance to someone in the group.
