NASA’s Juno Navigator allows detection of Jupiter Cyclone

The Configuration of Circumpolar Cyclones at Jupiter's South Pole.

NASA’s Juno Navigator allows detection of Jupiter Cyclone, Jupiter’s South Pole has a new cyclone. The big storm Jovian discovered on November 3, 2019, during a recent Jupiter flight at NASA to collect data from NASA spacecraft.

It was the 22nd flight where the solar-powered spacecraft collected scientific data about the gas giant and rose only 3,500 kilometers above its peak. The flight also means victory for the mission team, whose innovative actions save the solar-powered spacecraft from the darkness that can end the mission.

The combination of creativity and analytical thinking yields more results for NASA, the researcher said. We have learned that Juno’s orbit will place it under Jupiter’s shadow, which can have serious consequences if we have solar energy. There is no sunlight which means electricity, so there is a risk of freezing.

When the team tried to find a way to save energy and keep the core warm, the engineers had a completely new way out of trouble: Jupiter’s Jump shadow. It was nothing short of a brilliant navigation hit. Here we first make another fundamental discovery from the door to the other side.

With each flight of data, the data reinforces the idea that five storms in the pentagonal pattern revolve around the central storm at the South Pole and that the system appears stable. None of the six hurricanes showed signs of withdrawal so that other typhoons could join.

Then, during Juno’s 22nd scientific leak, smaller new typhoons began to live and join the battle.

The Janov Infrared Auroral Cartridge Instrument [JIRAM] data shows that we are moving from a pentagon of a cyclone that surrounds one in the middle to a hexagonal arrangement.

By examining the weather layer up to 50 to 70 kilometers beneath Jupiter’s clouds, JIRAM captures the infrared light that radiates deep inside Jupiter. His data shows that the speed of the new typhoon averages 362 km / h, comparable to the speeds of six more established polar peers.

JunoCam from the spacecraft also received images with visible light from the new cyclone. Two data sets provide information about atmospheric processes not only from Jupiter but also from other gas giants such as Saturn, Uranus, and Neptune, as well as exoplanets, currently found; They even explained the terrestrial cyclone’s atmospheric processes.

This storm is a new meteorological phenomenon that has never observed or predicted. Nature is currently discovering new physical properties about the fluid movement and the functioning of the giant atmosphere on the planet.

We began to understand through observation and computer simulation. Juno’s overflight in the future will help us improve our understanding by showing how cyclones evolve.

Of course, the new cyclone would never found if Juno froze to death during a solar eclipse when Jupiter fell between a spaceship and heat and sunlight.

Juno has been in space since 2011. On July 4, 2016, an initial 53-day orbit began around Jupiter. First, the orbit must be shortened a few months later to shorten the time between scientific flights of the gas giant. every 14 days.

But, the project team advised NASA to stop burning the main engine because of concerns about the spacecraft’s fuel system. The 53-day Juneau Orbit provides all scientific knowledge according to the original plan. need more time to do it. Juno’s longer life on Jupiter means that Jupiter’s shadow must be avoided.

From the day we entered orbit around Jupiter, we made sure it remained in the sun around the clock, researchers said. Our navigators and engineers have told us that there is a day of reckoning when we enter Jupiter’s shadow in about 12 hours.

Without the sun’s energy-producing rays, Juno cooled below the test level and empties the battery cells after recovery. So, the navigation team has a plan to “jump in the shadows” and maneuver the spacecraft so that the track misses the eclipse.

The navigator calculated that if Juneau fired a rocket weeks before November 3 when the spacecraft was deep in Jupiter’s orbit, Juneau could change its trajectory so the eclipse slipped. Maneuvers will use a spacecraft response control system that was not intended to maneuver this size and duration.

On September 30, at 7:46 pm EDT (4:46 pm PDT), the reaction control system started. It ended 10 hours later. The propulsion maneuver – five times longer than using the previous system – changed the speed of the Juno orbitals to 203 km / h and consumed around 73 kg of fuel. Thirty-four days later, the spaceship’s solar fields turned sunlight into electrons that had not destroyed when Juneau screamed behind Jupiter’s clouds again.
