In this March 26, 2015 file photo, U.S. astronaut Scott Kelly, (right), crew member of the mission to the International Space Station, stands behind glass in a quarantine room, behind his brother, Mark Kelly, also an astronaut, after a news conference in the Russian-leased Baikonur, Kazakhstan cosmodrome. Nearly a year in space put Scott Kelly's immune system on high alert and changed the activity of some of his genes compared to his Earth-bound identical twin, according to a report released on Friday, Feb. 15, 2019.

This composite image made from a series of Jan. 23, 2018 photos shows a self-portrait of NASA's Curiosity Mars rover on Vera Rubin Ridge. On Thursday, June 7, 2018, scientists said the rover found potential building blocks of life in an ancient lakebed and confirmed seasonal increases in atmospheric methane. The rover's arm which held the camera was positioned out of each of the dozens of shots which make up the mosaic. (NASA/JPL-Caltech/MSSS via AP)
