We’ve learned a lot about Neptune’s largest moon, Triton, since it was first discovered in 1846. Some scientists believe it could be an “ocean world” with liquid water – and maybe even harbor life.
And now, pending approval, we might soon get our best glimpse yet. NASA’s Jet Propulsion Laboratory proposed on Tuesday at a conference in Texas to send a spacecraft called “Trident” to Triton – with the goal of sussing out whether it’s a habitable world.
Rather than spending billions of dollars, the proposed spacecraft called Trident aims to keep costs low – roughly the “price of a small mission to the moon,” in the New York Times’ reckoning.
“The time is now to do it at a low cost,” said Louise Prockter at Tuesday’s Lunar and Planetary Science Conference in Texas, director of the Lunar and Planetary Institute in Houston and the principal investigator of the proposed mission.
“And we will investigate whether it is a habitable world, which is of huge importance.”
Along with a Triton flyby, Trident would also visit Jupiter’s moon Io and stop by Venus – it’s been almost twenty years since NASA’s Cassini-Huygens spacecraft visited the second planet from the Sun.
