Kepler has found more than 5000 exoplanet candidates so far, and confirmed about half of them.
The sperm will eventually make its way back to a lab at the University of Kansas for further testing, according to another press release, where one of the scientists coordinating the study will perform further experients to see how time in space changed its behavior.
TESS will look at the nearest and brightest stars in the whole sky while it's in a high elliptical orbit of Earth.
By combining global data from NASA satellites with the ship, aircraft, and autonomous assets such as floats, along with laboratory research and balloon data, boffins are able to not only understand the current state of the atmosphere, but also how it is evolving over time.

How do you find exoplanets?
You can directly image them, but this is very hard, and only captures the largest planets, and those in the most distant orbits around their stars.
NASA is leading the study of the world's largest phytoplankton bloom in the North Atlantic to see how the tiny sea critters influence the climate in every season on our planet. You can even use spacetime itself, as a planet's gravity forms a gravitational lens, warping the light from stars directly beyond your star of interest. This involves watching a star for dips in its light as a planet passes between the star and the telescope. Kepler and TESS have a different, but similar approach, to do that.
"We learned from Kepler that there are more planets than stars in our sky, and now TESS will open our eyes to the variety of planets around some of the closest stars", said Paul Hertz, Astrophysics Division director at NASA Headquarters. This will provide much more information on these targets, as the spacecraft's cameras spend a total of 27 days on each sector of space. In the first year of the observations, it will map the 13 sectors encompassing the southern sky, and the second year will map the 13 sectors of the northern sky.
TESS will tell James Webb what to look at, and the powerful telescope can look for the planets' atmosphere traces.
"Based on previous experiments, it seems the lack of gravity facilitates sperm mobility", Fathi Karouia, lead scientist for NASA's space biology project, was quoted as saying.
