An era closes.
POWERING DOWN
The clock is ticking for Voyager space vehicles 1 and
2. Voyager 1 has gone farther since being launched in 1977, along with its
twin, than any other manmade space vehicles in human history — but NASA says
they'll soon run out of power.
News outlets have been reporting attempted cuts and
reductions of the Voyagers for a while, including in 2005 and again in 2021.
But this week's Scientific American report makes it clear that this time it's
goodbye for good.
"We're at 44 and a half years," Ralph
McNutt, Johns Hopkins University a physicist, told the publication. "So
we've done 10 times the warranty on the darn things."
REMEMBER ME
The vehicles are expected to completely run out of
power by 2025, and NASA has been cutting off features as necessary to extend
their lives until then.
It will certainly be interesting to see how Earth's
Voyager fans memorialize their missions. Remember how people mourned when the
Mars Opportunity Rover died?
The science Voyager conducts is as relevant as ever,
so there's no reason to think it won't be just as missed. In fact, a team of
researchers published findings obtained from Voyager data yesterday in The
Astrophysics Journal.
The twin Voyagers deserve a sentimental send off, but
even if they don't get one, they'll leave behind decades of scientific data
about the cosmos as their legacy.
