Late Tuesday night, scientists at NASA’s Jet Propulsion Laboratory sent their final data uplink to the Opportunity rover on Mars. Over this connection, via the Deep Space Network, the American jazz singer Billie Holiday crooned “I’ll Be Seeing You,” a song that closes with the lines:
I’ll find you in the morning sun
And when the night is new
I’ll be looking at the moon
But I’ll be seeing you
The scientists waited to hear some response from their long-silent rover, which had been engulfed in a global dust storm last June, likely coating its solar panels in a fatal layer of dust. Since then, the team of scientists and engineers has sent more than 835 commands, hoping the rover will wake up from its long slumber—that perhaps winds on Mars might have blown off some of the dust that covered the panels.
So on Tuesday night, they listened. They reminisced. But in the end, no response came. Opportunity would finally be declared dead on Sol 5352, as in five thousand, three hundred, and fifty-two days on Mars. NASA is expected to make it official at 2pm ET Wednesday, when NASA Administrator Jim Bridenstine and the chief of the agency’s science division, Thomas Zurbuchen, convene a news conference.
Opportunity landed on Mars more than 15 Earth years ago, on January 25, 2004. So much time has passed since then. Facebook would not be created until a month later. YouTube would not get its first video upload for more than a year. George W. Bush was still in his first presidential term. NASA’s Cassini spacecraft had not yet even arrived in the Saturn system.
And yet from that moment on, Opportunity and its sister rover Spirit began plugging along the surface of Mars. Originally designed for 90-day lifetimes, the rovers persisted. Spirit lasted until 2010, when its batteries were unable to keep the spacecraft’s critical components from freezing.
