NASA’s new planet hunter named the Transiting Exoplanet Survey Satellite (TESS), which was launched in April this year, has started its search for alien world around nearby stars.

TESS officially kicked off its science operations on July 25. It is expected to transmit its first science data back to Earth in August. After that, it will send the information periodically every 13.5 days, once per orbit, as the spacecraft makes its closest approach to Earth, NASA said in a statement.

“I’m thrilled that our new planet hunter mission is ready to start scouring our solar system’s neighborhood for new worlds,” said NASA Astrophysics Division Director Paul Hertz.

“Now that we know there are more planets than stars in our universe, I look forward to the strange, fantastic worlds we’re bound to discover,” Mr Hertz said.

TESS’ job will be to search for planets outside our solar system. Such planets are known as exoplanets.
