Engineers at NASA’s Johnson Space Center in Houston will be conducting a pressure test on Saturday, July 9, that will result in a sudden burst of noise from 11AM until 12PM (noon). The test will cause a loud boom that may sound like an explosion to people in the vicinity.
Specifically, the full test will begin at 8AM with the culminating boom likely to come between 11 a.m. and noon. People nearby and in surrounding neighborhoods and communities likely will hear the test, which will be conducted at the Energy Systems Test Activity area, and only if weather conditions permit.
