LATER today, Nasa will launch the TESS satellite into space, where it’ll hunt for undiscovered exoplanets orbiting stars.
Want to watch the Nasa TESS launch? We’ve got a livestream video below, plus all the details on the start time and what TESS is designed to do.

What time does the Nasa TESS satellite take off?
The Nasa TESS launch is scheduled to take place on Monday, April 16.
We’re expecting take-off to begin at 11.32pm UK time – or 6.32pm on the east coast of America.
However, the livestream should begin at 11.15pm, so make sure to tune in then so you don’t miss it.
It’s worth noting that rocket launches are famously difficult to pull off successfully, so it’s possible that the launch time may not be exact.

What is the Nasa TESS satellite?
TESS is a survey satellite, so it’s job is to go into space and gather information.
It’s part of Nasa’s search for planets outside of our solar system, including ones that might support life.
It’ll work by finding exoplanets that block light from their host stars – that’s called a “transit”.
TESS will be surveying 200,000 of the brightest stars near the sun to find these transiting planets.
“TESS scientists expect the mission will catalog thousands of planet candidates and vastly increase the current number of known exoplanets,” explains Nasa.
“Of these, approximately 300 are expected to be Earth-sized and super-Earth-sized exoplanets, which are worlds no larger than twice the size of Earth.”
TESS will be surveying the entire sky over two years, breaking it up into 26 different sectors.
Using powerful cameras, the spacecraft will “stare” at each sector for at least 27 days, looking at the brightest stars.
