NASA's Dr Martin Still also said in a blog: "We expect to find a whole range of planet sizes between planets the size of Mercury or even the moon, our moon, to planets the same size as Jupiter and everything in between". Exoplanets are planets outside the solar system.
"TESS is going to dramatically increase the number of planets that we have to study", said Ricker.
TESS's launch had appeared on track earlier in the day, when SpaceX reported the weather was 80 percent favorable.
The satellite will seek to find exoplanets that have the most promising conditions for supporting life, NASA said.
In a tweet, the aerospace company said the team was standing down to run additional analyses on the guidance, navigation and control systems. Meanwhile, SpaceX will stay busy with some important launches like the debut of its "Block 5" Falcon 9 rocket.
"That is about 20 times what the Kepler mission was able to detect". "It's a reliability upgrade that combines reliability and reusability".

TESS's prime mission is to survey up to 200,000 stars for a period of two years, with the goal of finding potential exoplanets that might be orbiting them.
Some might have Earth-like qualities, others may be unrecognizable.
"One of the numerous stunning things that Kepler let us know is that planets are all over the place and there is a wide range of planets out there". "Everybody always says, what's your favorite exoplanet?"
