NASA is preparing to launch a groundbreaking aircraft across the United States that’s faster than the speed of sound, travels without the noise. The X-59, a joint project between NASA and Lockheed Martin, is designed to reach speeds of over 900 mph, shattering the sound barrier of 761 mph.

Unlike traditional supersonic aircrafts, the X-59 is engineered to avoid the typical sonic boom. Instead of a loud, thunderous clap, it’s expected to deliver more of a “thump,” similar to a car door slamming.

NASA is conducting extensive testing to verify the aircraft’s ability to travel at such speeds without causing excessive noise. A recent social media post showed flames shooting from the jet during an engine test in California, confirming its capability to reach high speeds.

Lifting the ban on supersonic flights

The X-59 could be the key to lifting the U.S. government’s ban on supersonic flights over the country. Currently, aircrafts that break the sound barrier create a sonic boom, which officials said can be disruptive to communities below the path of flight. If successful, the X-59 could change that, opening the door for commercial supersonic air travel.

NASA plans to conduct a series of flights to measure the shockwaves the X-59 generates during its journey. The goal is to gather data on public reactions and the aircraft’s performance, specifically its ability to limit noise disruption in residential areas.

NASA spent decades researching designs to make supersonic flight over populated areas feasible. The X-59 is part of the agency’s broader mission to explore new possibilities in aviation, including faster travel times and improved medical response capabilities.

Competition in supersonic aviation

Meanwhile, Boom Supersonic, a Colorado-based company, is also making strides in the race to develop supersonic airliners. The company’s XB-1 jet made headlines with its first successful flight on Tuesday, Jan. 28. Now, with 12 flights, Boom Supersonic broke the sound barrier over California, claiming the title of the world’s fastest airliner.

The X-59’s first public flight is expected to take place later this year, with plans to fly over U.S. residential areas as part of its test campaign.
