Astronomo amateurs help determine the Juno Path


NASA's nuclear space decided to fly across the Great Red Spot of Jupiter, the Earth's improvements on the intelligence of the intrusion disorder.

It is an effort to plan observation in Juno's Juno space, and should know Candice Hansen (Planetary Science Institute). As a scientist in charge of JunoCam, like a single camcorder camera, he spends a lot of time chatting with astronomers, explaining what is happening in Jupiter's atmospheric turmoil. Intel is an essential part of JunoCam where a spacecraft passes through another planet.

But lately, the world of Jupiter's world of fans has helped the mission scientists, specifically where Juno has to fly. Last week, when he talked about a Washington DC Geophysical Union meeting, D.C., Hansen described how Juno's amateurs' army was a key player in deciding whether or not to break a Jupiter Big Red Fever.

Hans sat down Sky and telescope Talk about the role played by astronomers and amateurs in the upcoming weekend.

Juno is in the midst of mapping the depth of Jupiter's interior in July or July 2016 in orbital polar bearings. Vessels provide more time for the planet remotely, but every 53 days, it is low and faster, when it passes from the north pole to the south, approximately 2 hours. Near the equator, the tube circles approximately 200,000 kilometers per hour (150,000 mph) about a thousand miles in the cloud tops.

In each of these approaches, the mission scientists can measure the Juno velocity to control the length of the flight. While planning the eighth flybya space Season 18 The mission statement – scientists realized that the original 18-season plan for the Red Spot Red Cross had a 25-season plan.

But John Rogers, an amateur astronomer, head of the Jupiter Department of the British Astronomical Association, was careful. "John warned us before doing this, surely, even if Red Spot Red is to be there," says Hansen.

Back during the season 9 – October 24, 2017 – JunoCam imagined an atmospheric disturbance far from the Red Spot. Rogers, who keep Jupiter fans in tile around the world, has recognized what it was like immediately: the turbulent Moor known as Tropical Hurricane. Dark-skinned nights appear occasionally on the Red Spot Grande latitude. . . and has a story that sheds light on the most famous cousin.

Tropical Trojan War In 1901 another amateur and British military officer Percy Molesworth was discovered. It was stuck until 1939, cutting the Red Spot Large eight times. Writing in the British Astronomical Association in 1997, Richard McKim described Molesworth's mess as "the normal pattern of alternating shades of obscure belt and white shining in the dark south-western part of Jupiter's south shore." Since then, he appeared seven times, adapting to a destination ship Voyager 2 in 1979.

Rogers knew this story as well, and also knew that the Tropical Hive Rifle changed the speed of the original Roque Red during the Jupiter sky. This event was lost by the Red Spot meeting with Juno in February 2019.

"We had to wait a bit, we could see how everything came out," says Hansen. He and his colleagues convinced most of the project managers to spend as much time as possible, with their daily updates from the amateur, along with Red Spot and Disturbance.

Ground-based observations Disturbance showed fear of reaching Red Spot Redo in February of 2018. Over the next two months, in the darkness around the Earth's boundary, the Three Tropical Caverns again shook the storm. On April 12, Juno reached 10 degrees to the east of the Great Red Spot, and when he saw the distances away, he grew slightly bending.

The data made by amateur astronaut were invaluable, says Hansen. In the end, the team decided to go out and test February's near Red Spot. "We can not fly more than fly in the middle," he says, "but it will be enough to do what we want to do."

This is not the first time that Juno's Great Red Spot was sculpted. On July 2, 2017 (7 periods), the spacecraft was directly exploring the roots of the mammoth storm with its microwave antenna. Thanks to these data, Leku – 1.3 times the Earth's width – extends 300 km (200 miles) below the cloud deck.

During the next stroll, Juno will examine the area of ​​gravity above the storm, which moves around excess mass. The researchers follow the Jupiter's gravity map in Juno's low speeds, revealing on Earth's Doppler shifts. Combining microwave and gravitational data, scientists should learn a lot about the vertical location structure, says Hansen.

Amateurs were always part of the mission. JunoCam was designed to be a citizen science camera, an observation made by Earth hobbyists, where the "next image" was constantly updated. And without the dedication of JunoCam's professional video-cleaning professionals, the missions have given data to the most enlightening audiences, and they have begun to produce surrealist Jovian scenes, often fused with science and art.

"One of the best things about amateur astronomers is to spend a night at night and decide what they want to look at," says Hansen. "They are really good to see if the community of the best location changes … It's based on the beginning of the task of finding out what is happening to Jupiter."

Until now, however, interactions have been limited to decisions that were made about the camera. But the potential of the South Tropical Range and the Earth's Great Ground, as Hansen says, "this is the first time that really affects the design of our mission."
