Today (6/24), during accurately 9:57 and 48 seconds a.m. PDT, NASA’s Juno booster was 5.5 million miles (8.9 million kilometers) from a Jul 4th appointment with Jupiter. Over a past dual weeks, several milestones occurred that were pivotal to a successful 35-minute bake of a rocket motor, that will place a robotic path-finder into a frigid circuit around a gas giant.

“We have over 5 years of spaceflight knowledge and usually 10 days to Jupiter circuit insertion,” pronounced Rick Nybakken, Juno plan manager from NASA’s Jet Propulsion Laboratory in Pasadena, California. “It is a good feeling to put all a interplanetary space in a rearview counterpart and have a biggest world in a solar complement in a windshield.”

On Jun 11, Juno began transmitting to and receiving information from Earth around a clock. This consistent hit will keep a goal group sensitive on any developments with their booster within tens of mins of it occurring. On Jun 20, a protecting cover that shields Juno’s categorical engine from micrometeorites and interstellar dirt was opened, and a module program that will authority a booster by a all-important rocket bake was uplinked.

As Juno creates a initial approach, a hulk planet's 4 largest moons -- Io, Europa, Ganymede and Callisto -- are visible, and a swapping light and dim bands of a planet's clouds are only commencement to come into view.

One of a vicious near-term events remaining on Juno’s pre-burn channel is a pressurization of a thrust complement on Jun 28. The following day, all orchestration not geared toward a successful insertion of Juno into circuit around Jupiter on Jul 4 will be incited off.

“If it doesn’t assistance us get into orbit, it is close down,” pronounced Scott Bolton, Juno’s principal questioner from a Southwest Research Institute in San Antonio. “That is how vicious this rocket bake is. And while we will not be removing images as we make a final proceed to a planet, we have some engaging cinema of what Jupiter and a moons demeanour like from five-plus million miles away.”

The goal visual camera, JunoCam, imaged Jupiter on Jun 21, 2016, during a stretch of 6.8 million miles (10.9 million kilometers) from a gas giant.  In a image, only to a right of core is Jupiter, with a particular swirling bands of orange, brownish-red and white. To a left of Jupiter (from right to left) are a planet’s 4 largest moons — Europa, Io, Callisto and Ganymede. Juno is coming over Jupiter’s north pole, affording a booster a singular viewpoint on a Jovian system. Previous missions that imaged Jupiter on proceed saw a complement from most reduce latitudes, closer to a planet’s equator.

JunoCam is an overdo instrument — a inclusion in this goal of scrutiny was to concede a open to come along for a float with Juno. JunoCam’s optics were designed to acquire high-resolution views of Jupiter’s poles while a booster is drifting most closer to a planet.  Juno will be removing closer to a cloud tops of a world than any goal before it, and a picture fortitude of a large gas hulk will be a best ever taken by a spacecraft.

All of Juno’s instruments, including JunoCam, are scheduled to be incited behind on approximately dual days after achieving orbit.  JunoCam images are approaching to be returned from a booster for estimate and recover to a open starting in late Aug or early September.

“This picture is a start of something great,” pronounced Bolton. “In a destiny we will see Jupiter’s frigid auroras from a new perspective. We will see sum in rolling bands of orange and white clouds like never before, and even a Great Red Spot.

The Juno booster launched on Aug. 5, 2011, from Cape Canaveral, Florida.

JPL manages a Juno goal for a principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is partial of NASA’s New Frontiers Program, that is managed during NASA’s Marshall Space Flight Center in Huntsville, Alabama, for NASA’s Science Mission Directorate. Lockheed Martin Space Systems, Denver, built a spacecraft. The California Institute of Technology in Pasadena, California, manages JPL for NASA.
