Jupiter's Great Red Spot might fade into a great red memory in a few decades, according to planetary scientists.
The Great Red Spot on the largest planet in the solar system is a swirling storm which has been around since the 1600s. NASA's Juno probe transmitted stunning photos of the storm in July 2017.
In an email to Business Insider, a team member of the Juno mission, Glenn Orton, explained why storms on Jupiter last for a long time.
"They don't, at least not all of them. Think of the GRS [Great Red Spot] as a spinning wheel that keeps on spinning because it's caught between two conveyor belts that are moving in opposite directions. The GRS is stable and long-lived, because it's 'wedged' between two jet streams that are moving in opposite directions."
The $1 billion Juno spacecraft will take another peek at the Great Red Spot in April this year. The next viewing will be in July and in September 2019, and another flyby in December 2020.
According to Orton, they have no plans to "come as close without changing the orbit from its current configuration." They will also operate on the presumption that the drift rate of the GRS in Jupiter's atmosphere remains constant.
