A mesmerizing NASA video enables you to trip with the Juno spacecraft because it flies by Jupiter and its largest moon


NASA’s Juno spacecraft has been beaming photographs of Jupiter again to Earth since 2016, however a brand new video reveals what the view may appear to be from contained in the probe because it flies previous Jupiter’s roaring cyclones and big storms.
The footage additionally affords a front-row take a look at Jupiter’s largest moon, Ganymede – an icy orb bigger than Mercury.
Juno flew inside 1,038km of Ganymede final week – the closest any spacecraft has gotten to the moon in additional than twenty years. (The final method was by NASA’s Galileo spacecraft in 2000.) Lower than a day later, Juno performed its thirty fourth flyby of Jupiter, snapping photographs alongside the best way.
Citizen scientist Gerald Eichstädt compiled pictures from each of these journeys right into a time-lapse video that reveals what it’s wish to cross by the celestial our bodies. The video lasts three minutes and 30 seconds, however in actuality, it took Juno practically 15 hours to journey the 1,182,868km between Ganymede and Jupiter, then about three extra hours to journey between Jupiter’s poles.
Check out the video under:
The start of the footage reveals Ganymede’s cratered floor, marked by darkish patches that probably type as ice modifications straight from stable to fuel. When you look carefully, you possibly can see one in every of Ganymede’s largest and brightest craters, Tros, surrounded by white rays of ejected materials.
When it captured these pictures, Juno was touring at a pace of roughly 66,949km per hour. However because the spacecraft bought nearer to Jupiter, it picked up pace: The planet’s gravity accelerates Juno to just about 209,215km per hour throughout its flybys.
The video reveals Jupiter’s turbulent floor rising from the darkish abyss of house like a watercolor portray. White ovals point out a set of big storms in Jupiter’s southern hemisphere often known as the “string of pearls.” (There are 5 of them within the video.) Flashes of white mild symbolize lightning.
“The animation reveals simply how stunning deep-space exploration might be,” Scott Bolton, Juno’s principal investigator on the Southwest Analysis Institute in San Antonio, Texas, mentioned in a press release.
He added: “As we speak, as we method the thrilling prospect of people with the ability to go to house in orbit round Earth, this propels our creativeness many years into the long run, when people can be visiting the alien worlds in our photo voltaic system.”
Juno has already solved a few of Jupiter’s mysteries

Juno flies in an elliptical orbit round Jupiter, getting near the planet as soon as each 53 days. Its current shut cross to Ganymede, nonetheless, shortened that orbit to 43 days.
The spacecraft’s principal purpose is to achieve perception into Jupiter’s origins and evolution by mapping its magnetic fields, finding out its northern and southern lights (or auroras), and measuring components of its ambiance – together with temperature, cloud motion, and water concentrations.
The spacecraft entered Jupiter’s orbit in July 2016. (Jupiter is roughly 390 million miles away from Earth.) Its mission was initially supposed to finish this month, however NASA has prolonged Juno’s lifespan by way of 2025.

Juno’s earlier flybys have yielded vital discoveries, like the truth that most of Jupiter’s lightning is concentrated at its north pole. The spacecraft additionally discovered that storms have a tendency to look in symmetrical clusters at Jupiter’s poles, and that the planet’s highly effective auroras produce ultraviolet mild that’s invisible to human eyes.
Simply this week, Juno’s measurements helped scientists work out why these auroras type within the first place: Electrically charged atoms, or ions, “surf” electromagnetic waves in Jupiter’s magnetic discipline earlier than crashing into the planet’s ambiance.
