Washing machine sized satellite to scan more than 200,000 stars for planets
TAMPA, UNITED STATES: NASA is poised to launch a $337 million washing machine-sized spacecraft that aims to vastly expand mankind's search for planets beyond our solar system, particularly closer, Earth-sized ones that might harbor life.
The Transiting Exoplanet Survey Satellite, or TESS, is scheduled to launch Monday at 6:32 pm (2232 GMT) atop a SpaceX Falcon 9 rocket from Cape Canaveral, Florida.
Its main goal over the next two years is to scan more than 200,000 of the brightest stars for signs of planets circling them and causing a dip in brightness known as a transit.
NASA predicts that TESS will discover 20,000 exoplanets -- or planets outside the solar system -- including more than 50 Earth-sized planets and up to 500 planets less than twice the size of Earth.
"They are going to be orbiting the nearest, brightest stars," Elisa Quintana, TESS scientist at NASA's Goddard Space Flight Center, told reporters on Sunday.
"We might even find planets that orbit stars that we can even see with the naked eye," she added.
"So in the next few years we might even be able to walk outside and point at a star and know that it has a planet. This is the future."
TESS is designed as a follow-on to the US space agency's Kepler spacecraft, which was the first of its kind and launched in 2009. Now, the aging spacecraft is low on fuel and near the end of its life.
Kepler found a massive trove of exoplanets by focusing on one patch of sky, which contained about 150,000 stars like the Sun.
The Kepler mission found 2,300 confirmed exoplanets and nearly 4,500 candidates. But many were too distant and dim to study further.
TESS, with its four advanced cameras, will scan an area that is 350 times larger, comprising 85 percent of the sky in the first two years alone.
"By looking at such a large section of the sky -- this kind of stellar real estate -- we open up the ability to cherry-pick the best stars to do follow up science," said Jenn Burt, a postdoctoral fellow at the Massachusetts Institute of Technology (MIT).
"On average the stars that TESS finds observes be 30-100 times brighter and 10 times closer than the stars that Kepler focused on."
Since TESS uses the same method as Kepler for finding potential planets, by tracking the dimming of light when a celestial body passes in front of a star, the next step is for ground-based and space telescopes to peer closer.
The Hubble Space Telescope and the James Webb Space telescope, scheduled to launch in 2020, should be able to reveal more about planets' mass, density and the makeup of their atmosphere.
"TESS forms a bridge from what we have learned about exoplanets to date and where we are headed in the future," said Jeff Volosin, TESS project manager at NASA's Goddard Space Flight Center.
By focusing on planets dozens to hundreds of light-years way, TESS should be a stepping stone to future breakthroughs, he said.
"With the hope that someday, in the next decades, we will be able to identify the potential for life to exist outside the solar system."
Weather was expected to be 80 percent favorable for launch.

Allahabad HC orders probe into 'reinstatement' of teacher in UP's Barabanki
Lucknow (PTI): The Lucknow Bench of the Allahabad High Court on Friday ordered a probe by the special task force (STF) into alleged irregularities in the rejoining of a teacher at City Intermediate College in Barabanki, observing that the reinstatement appeared to be prima facie illegal.
The court also directed the recovery of the salary paid to the teacher during the disputed period.
A bench of Justice Rajeev Singh passed the order on a petition filed by the college management committee. The court expressed doubts over the roles of the District Inspector of Schools (DIOS), Barabanki, the college principal and the teacher concerned and hence, directed a detailed inquiry into the matter.
Taking note of alleged manipulation of records and misleading submissions, the court ordered the immediate transfer of the Barabanki DIOS to ensure a fair probe. It also directed the initiation of disciplinary proceedings against the then joint director of education of the Ayodhya division.
In its order, the court found that the teacher, Abhay Kumar, was initially appointed as an assistant teacher in 2018 but joined an Eklavya Model Residential School in Chhattisgarh as a lecturer in June 2024 without obtaining permission from the management. His subsequent request to retain the lien was rejected.
Despite this, he was allowed to rejoin the Barabanki College in September 2025 on the directions of the joint director of education and the DIOS, and was even paid the salary for October 2025. The court termed the rejoining "wholly illegal" and lacking any legal basis.
The bench also expressed concern over lapses in communication within the education department and directed the Uttar Pradesh chief secretary to ensure that official orders are communicated through email and WhatsApp as well, to prevent disputes.
The matter is next listed for hearing on May 28 when a compliance report is sought.
