NASA’s spacecraft Juno rose directly on the buyer’s South Pole when the JunoCam got this image on February 2, 2017 at 6:06. M. PT (9:06. M., F) from a height of about 62,800 miles (101,000 kilometers) above the cloud tops. Credit: NASA
“NASA’s” Juno mission to Jupiter, which was in orbit around the gas giant since July 4, 2016, still in its development to the current 53-day orbit for the remainder of the task. This will allow Juno to ride the std of the old science, while avoiding the risk of previously-planned engine firing would reduce the spacecraft’s orbital period is 14 days.
“Juno is healthy, science The whole instrument and the data and images we have received is nothing short of amazing,” said Thomas Zurbuchen, minerals for NASA’s science mission Directorate in Washington. “The decision to abandon the burning is the right thing to do—to maintain the value of the assets so that Juno can be used sexually exciting journey of discovery.”
Juno is successfully orbiting the planet Jupiter four times since his arrival to the giant planet, with the latest orbit completed in February. 2. Sti next investigation near the planet Jupiter will be 27 March.
the orbital period does not affect the quality of the science that was collected by Juno on each investigation since the height above the planet Jupiter will be the same at the time of closest approach. In fact, the orbit provides new opportunities to enable further exploration of the Far reaches of space dominated by Jupiter’s magnetic field, increasing the value of Juno search.
during each orbit, Juno low altitude above Jupiter’s cloud tops — the closest is about 2600 miles (4,100 kilometers). Through these investigations, the Juno probe under the opacity of cloud cover and studies the buyer’s Aurora to learn more about the planet Earth from the origins of the structure of the atmosphere and the magnetosphere.
The original Juno flight plan depicting the spacecraft loops around Jupiter twice in a 53-day orbit, then the reduction of sexually transmitted diseases the orbital period to 14 days for the remainder of the mission. However, two of the helium check valves that are part of the plumbing of the spacecraft Main Engine not work as expected when the defense system of the CD in October. Measurement of the spacecraft that took several minutes duty to open, while it took only a few seconds through main engine firing.
“through a comprehensive review, we look at several scenarios that will place Juno in the shortest period of orbit, but there was concern that another main engine burn can lead to less than desirable orbit,” said Rick Nybakken, Juno Project Manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The bottom line is burning represents a danger to the completion of the Juno science objectives.”
Juno largest the 53-day orbit, the so-called “bonus science” that wasn’t part of the original mission design. Juno wants to explore more of the ends of the jovian magnetosphere—the region of space dominated by Jupiter’s magnetic field—now including the magnetotail South magnetic, and the magnetosphere of the earth the boundaries of the region called the magnetopause. Understanding of the magnetosphere and how it interacts with the solar wind is the key science objectives of NASA’s pop-up science division.
“another major advantage of longer orbits is that Juno will spend less time in strong radiation belts on every orbit,” said Scott Bolton, Juno Principal Investigator from the southwest Research Institute in San Antonio. “This is important because the radiation was a major life-limiting factor for Juno.”
Juno will continue to work within the current budget line through July 2018 a total of 12 science orbits. The team can then propose the extension of the mission through the science review session. Review the process of re-evaluation of the proposed mission extension on merit and the previous value and the expected science return.
The Juno science team continued to improve returns from the previous investigations. Revelations include that the buyer’s magnetic field Aurora are bigger and more powerful than it was originally thought that belts the regions that give the gas giant cloud top sti a distinctive look that extends deep into the Earth ” from the inside. Peer-reviewed papers with more in the results of Juno for the first three investigations and is expected to be published within the next few months. In addition to the mission JunoCam—the first planetary information and the time the camera is now guided with the help of the audience. People can participate by voting, one that contains the buyer to be photographed during each investigation.
“Juno is providing amazing results we formulate our thoughts and how the giant planet of action,” said Bolton. “It will be just as amazing as with the original plan.”
