The Juno to Jupiter mission was extended to September 2025, or how long the spacecraft can operate around Jupiter.
While Juno has focused solely on the giant planets, the expansion of the mission will include observing the rings of Jupiter and the large moons with the planned close-up observation of targets and flies of the Ganymede Euro moon. Napa and Io
This will be the first near-moon flight since the Galileo mission 1995-2003.
“One of the exciting things about this mission. [extension]Scott Bolton, Juno’s Principal Investigator, said in September 2020 at a meeting of NASA’s Exoplanet Advisory Group. “We are going to visit satellites and rings. It really became a full-blown system explorer, not focused on the core mission, so it was able to pull in a more diverse community as satellite geologists, all of whom would get the information I thought. Interesting and unique “
Juno made his discoveries about Jupiter’s internal structure, magnetic fields and magnetic fields and found that the dynamics of the atmosphere are more complex than scientists previously thought.The JunoCam on board provided a beautiful view of the gas giant Earth. Space photography enthusiasts expect that the view of Galilean’s Moon Junocam should be nothing short of exciting.June took a distant image of the Ganymede moon in 2020.
Juno arrived in Jupiter in July 2016 and the mission originally predicted was February 2018 as the spacecraft will be in close proximity to Jupiter and its radiant environment. Extreme “operating conditions” are expected to eventually render the spacecraft unusable.
But mission plans changed when problems with the spacecraft’s main engines soon after Jupiter arrived. The spacecraft was originally going to have a 14-day near-earth orbit, but in late 2016, mission managers opted not to perform the final firing of the rocket for that orbit due to the instability of the engine’s reliability.
But the revision plan kept Juno in orbit 53 days. This meant that the entire mission was scientifically slow. However, Bolton said the slower pace was “Frugal” Juno received less intense radiation, making the mission last longer than originally planned.
“I think the lesson is that we have flexibility, and that’s a good thing about the mission,” Bolton said in September, “so when you design missions, try to be flexible because you don’t know what the curves you’re going to throw. ”
NASA is also expanding its InSight mission to Mars for another two years, running through December 2022.The spacecraft and the InSight team have installed and operated a highly sensitive seismograph, measuring Mars and collecting data about it. Strong tectonic movements on the red planet, as well as deepening our knowledge Of the dynamics of the atmosphere, magnetic fields and the internal structure of the planets.
An independent review committee recommended both mission extensions to NASA.
“A senior review has verified that these two planets’ scientific missions are likely to lead to new discoveries and raise new questions about our solar system,” said Lori Glaze, Science Director. Planet at NASA headquarters in Washington, “I would like to thank a member of the Senior Examiner for the comprehensive analysis, and I’d like to thank the mission team as well, who now provide an exciting opportunity to refine our understanding of theology. The dynamic science of Jupiter and Mars “
NASA said the extended missions took advantage of large investments in these missions, enabling ongoing science operations at a lower cost than developing new missions. Long-term further valuable information, while in other cases, will allow the mission to visit new targets with entirely new scientific goals, ”NASA said in a press release.
