NASA’s chief scientist is confident evidence of life beyond Earth will soon be found.
In a NASA media event April 7, Ellen Stofan said she thought scientists would find “strong indications” of extraterrestrial life in a decade, and “definitive evidence” of it in 20 to 30 years. John Grunsfeld, NASA associate administrator for science, concurred, saying we are “one generation away” from finding life both elsewhere in our solar system and in other solar systems.
