Residents in parts of central and eastern Pennsylvania will get an opportunity on Wednesday night to catch a peek at the vapors from several rockets launching from NASA’s Wallops Island Flight Facility in Virginia.
Tonight’s launch window will open at 10:30 p.m. and last through 3:30 a.m. Thursday, NASA said. This will be the latest of several attempts by the space agency, which had to scrub earlier ones due to weather conditions.
Called the Turbulent Oxygen Mixing Experiment Plus, or TOMEX+, it’s a NASA sounding rocket mission that will investigate the mesopause, one of Earth’s most turbulent atmospheric regions. The mesopause is a region of the upper atmosphere that stretches from about 53 to 65 miles (85 to 105 kilometers) in altitude, at the boundary between Earth’s mesosphere and thermosphere, NASA wrote in an explanation of the mission. It is the coldest layer of our atmosphere.
This mission is a follow-up to the original TOMEX sounding rocket that launched in 2000. This time, the mission will use three rockets instead of one. The first two rockets will launch within a minute of each other and release vapor tracers, which are colorful clouds made from compounds similar to those in fireworks. The third rocket will launch about five minutes later and carry an instrument that will allow scientists to measure atmospheric density and motion over time.
Assuming this launch goes off as scheduled, the rockets should be visible over southcentral and southeastern Pennsylvania.
NASA plans to launch three rockets, including two with colorful vapor trails, in a 5-minute span. The rockets may be visible as far away as New Jersey.NASA Wallops Flight Facility
Viewers will need to look into the south-southeastern sky to see the streaks.
While the Wallops Visitor Center will not be open for public viewing of the rockets, NASA plans to provide a livestream on YouTube, beginning five minutes before the launch.
