After 12 missions to the International Space Station, the space shuttle Endeavour has returned to Earth. This mission’s conclusion is bittersweet for Texas Tech University graduate Joel Tumbiolo.
“I worked Endeavour’s first launch in May 1992, and last in May 2011,” Tumbiolo said. “It’s a reason to be proud.”
Tumbiolo, a member of the 45 Weather Squadron at Patrick Air Force Base, Fla., is the Delta Program launch weather officer at Cape Canaveral Air Force Station. Since March 1991, he has led all weather support for both the space shuttles and expendable vehicles alike.
“We monitor lightning across the area and ground-wind constraints throughout the countdown, including pre-launch operations, launch countdown simulations, final terminal countdowns and post-launch data analysis,” Tumbiolo said. “Launch day can be very exciting, especially if there is weather in the area.”
Moments before a vehicle blasts off from Kennedy Space Center in Florida, a NASA test director calls for a status check from all flight directors monitoring the various systems crucial to launch. Tumbiolo is among those responding with a “go/no go” for launch.
“We follow a very specific list of safety constraints,” Tumbiolo explained. “If the data meets a certain criteria, launch must be postponed. And out of the more than 200 launches I’ve been a part of, I have probably scrubbed around 30 to 50 of them.”
Tumbiolo received an associate’s degree in geology from Vincennes University in 1981, followed by his bachelor’s in atmospheric science from Purdue University in 1983. And for his master’s, he decided on Texas Tech.
