In the early 1960s, scientists developed the gravity-assist method, where a spacecraft would conduct a flyby of a major body in order to increase its speed. Many notable missions have used this technique, including the Pioneer, Voyager, Galileo, Cassini, and New Horizons missions. In the course of many of these flybys, scientists have noted an anomaly where the increase in the spacecraft’s speed did not accord with orbital models.
This has come to be known as the “flyby anomaly”, which has endured despite decades of study and resisted all previous attempts at explanation. To address this, a team of researchers from the University Institute of Multidisciplinary Mathematics at the Universitat Politecnica de Valencia have developed a new orbital model based on the maneuvers conducted by the Juno probe.
The study, which recently appeared online under the title “A Possible Flyby Anomaly for Juno at Jupiter“, was conducted by Luis Acedo, Pedro Piqueras and Jose A. Morano. Together, they examined the possible causes of the so-called “flyby anomaly” using the perijove orbit of the Juno probe. Based on Juno’s many pole-to-pole orbits, they not only determined that it too experienced an anomaly, but offered a possible explanation for this.

It is a testament to the complexities of physics that even after sixty years of space exploration – and one hundred years since General Relativity was first proposed – that we are still refining our models. Perhaps someday we will find there are no mysteries left to solve, and the Universe will make perfect sense to us.

Planet x?
cool
Instead of taking a physics correspondence course, I opted to watch The Orville on Thursday nights to better understand spatial anomalies. I’ve found it helps.
The little Millennial cutey is....well...a cutey
Let’s send soroz HilLIARy and obama whatshisrealarabicnsme there to investigate.
Glowbal warming?
I find it amazing they even notice.
Personally I think they are forgetting carry a number.
Hmmm.
Just googled the Orvilles. From the cast pic, it looks similar to a choice between Mary Ann and Ginger.
I go for Mary Ann, btw.
Perhaps variations in the very tenuous atmospheres involved. I assume such matters are taken into account!
The calculations required for these maneuvers are insanely precise, challenging the average person’s comprehension of what “precise” really means, IMHO.
But then it is let slip that well, there is one iota of a scintilla of a fragment of uncertainty, and the popular mind is inflamed ... “It’s space aliens!”
Nice post!
Humans won't last that long.
Stopped off for cigarettes. And to play video games.
Nothing good comes next.
Solar system must be warming up from those California fires.
Fools. All they had to do is say there may be a link to climate change and cha ching.
Aren’t the masses of planets and moons really just estimates?
If a body doing the slingshot comes out with a wider orbit than expected, wouldn’t that mean the mass of the body it’s using for it’s pivot is less than estimated?
They will find this effect mostly in the vicinity of gas giant worlds like Jupiter due to ongoing ‘sporting events’ in Lunar-sized stadiums by the universe-wide Dweller civilization which has inhabited these sorts of worlds for billions of years.
“Juno isn’t exactly where it’s supposed to be...”
Well, you can’t drive there even though it’s the largest (in land area) city in America.
