NASA showed off for a new gravitational wave detection mission in space. The telescope is part of the mission led by the European Space Agency (NSA) in partnership with NASA.
The goal of the LISA mission is to position three spacecraft in a triangular orbit measuring nearly 1.6 million miles on each side. The three spacecraft will follow the Earth’s orbit around the Sun. Each spacecraft will carry two telescopes to track their siblings using infrared laser beams. Those beams can measure distances down to a trillionth of a meter.
Gravitational waves are created during a collision between two black holes. They were first theorized by Albert Einstein in 1916 and by the Laser Interferometer Gravitational-wave Observatory (LIGO) Scientific Collaboration from the National Science Foundation, Caltech and MIT. A gravitational wave is detected when the three spacecraft shift from their characteristic pattern.
The LISA mission is scheduled to launch in the mid-2030s. The detection of gravitational waves could provide “enormous potential” to better our understanding of the universe, including events like black holes and the Big Bang that are difficult to study through other means, according to the official mission website.
