Former NASA Scientist <br />Claims They Found Life on Mars <br />40 Years Ago According to Gilbert V. Levin, <br />Viking landers sent by NASA to Mars <br />in 1976 conducted an experiment <br />which he claims offers proof of life. Levin made the claims <br />in an article published <br />in 'Scientific American.' The experiment conducted <br />by the lander is known <br />as Labeled Release (LR). It sought to detect life by embedding <br />nutrients into Martian soil. It then tested <br />whether organic life had consumed the <br />nutrients, releasing evidence of metabolism. While the experiment seemed <br />to prove that life existed on Mars, <br />NASA was unable to reproduce <br />the result in a laboratory. Gilbert V. Levin, Former NASA Scientist, via CNN With new discoveries on Mars, Gavin <br />proposes a repeat of the LR experiment. <br />He suggests that the data be reviewed <br />by an independent, expert panel.
