All this ‘high frontier’ action comes amidst the utterly chaotic US government partial shutdown, that threatened the launch of the MAVEN Mars orbiter, has halted activity on many other NASA projects and stopped public announcements of the safe arrival of NASA’s LADEE lunar orbiter on Oct.
Bolton confirmed that the shutdown fortunately hasn’t altered or killed Juno’s flyby objectives. And some more good news is that Slooh will track the Juno Earth Flyby “LIVE” – for those hoping to follow along.
NASA’s Juno Jupiter-bound space probe will fly by Earth for essential speed boost on Oct 9, 2013. 97% of NASA’s employees are furloughed – including public affairs – due to the legal requirements of the shutdown! A full up science investigation of our Home Planet by Juno is planned, that will also serve as a key test of the spacecraft and its bevy of state of the art instruments. NASA’s Juno spacecraft blasted off atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. During a one year science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s genesis and evolution.
Viewers near Cape Town, South Africa will have the best opportunity to view the spacecraft traveling across the sky. Juno itself will most likely not be visible to the unaided eye, but binoculars or a small telescope with a wide field should provide an opportunity to view, according to a Slooh statement. Amidst the government shutdown, Juno prime contractor Lockheed Martin is working diligently to ensure the mission success.
What’s not at all clear is whether Juno will detect any signs of ‘intelligent life’ in Washington D.C.!
The Juno spacecraft was launched from Kennedy Space Center on August 5, 2011 toward Jupiter.
Juno will receive a huge boost from Eartha€™s gravity equivalent to about 70 percent of the total change in velocity, or delta-v, provided by the Atlas V 551 rocket. The spacecraft passes over the ocean off the coast of South Africa at the point of closest approach.
Juno arrives at Jupiter on July 4, 2016, to study the giant planeta€™s interior, atmosphere and giant magnetosphere. On the map & geometry images provided below, the red segments of the spacecrafta€™s path indicate the time when Juno is within Eartha€™s shadow. Viewers near Cape Town, South Africa will have the best opportunity to view the spacecraft traveling across the sky near closest approach (weather permitting). In addition, information about Junoa€™s position on the sky during and after the flyby, including sky charts, has kindly been made available by the satellite spotting website Heavens Above.
The Juno mission team welcomes images from amateur astronomers who attempt to photograph the spacecraft during and after the flyby.
Amateur radio operators are invited to join in sending a coordinated Morse code message that the spacecrafta€™s radio and plasma wave instrument may be able to detect.
The spacecraft first loops around the inner solar system, returning to the original distance from the Sun from which it was launched (Eartha€™s orbit). In 2006, the Pluto-bound New Horizons spacecraft was sent on a direct flight past Jupiter (its own gravity assist), reaching the giant planet in just one year.
The Juno spacecraft received a little over half of the boost it needs to get to Jupiter from its launch vehicle. The key to understanding how Juno and other spacecraft use gravity assists is recognizing that the spacecraft is in orbit around the Sun, not the Earth. This trio of Junocam views of Earth was taken during Juno's close flyby on October 9, 2013. The Sand Fire in the Santa Clarita Valley area of Southern California erupted on Friday, July 22, 2016, and rapidly grew to more than 37,000 acres.

The Juno team commanded the probe to take the image as part of the checkout phase of the vehicles instruments and subsystems. So far the spacecraft is in excellent health and the team has completed the checkout of the Waves instrument and its two Flux Gate Magnetometer sensors and deployment of its V-shaped electric dipole antenna. The team reports that Juno also performed its first precession, or reorientation maneuver, using its thrusters and that the first trajectory control maneuver (TCM-1) was cancelled as unnecessary because of the extremely accurate targeting provided by the Atlas V rocket.



JunoCam will collect new photos and the other science instruments will make measurements as Juno cartwheels past Earth during the slingshot to Jupiter. The goal is to find out more about the planets origins, interior structure and atmosphere, observe the aurora, map the intense magnetic field and investigate the existence of a solid planetary core.
NASA's Juno spacecraft and its spent Centaur upper rocket stage are captured in this telescope view as they move across the field of stars. Bolton is Juno’s principal investigator from the Southwest Research Institute (SwRI), San Antonio, Texas. 9, 2013, NASA’s Jupiter-bound Juno spacecraft is making a quick pass to get a gravity boost from the mother planet. 5, 2011 to begin a 2.8 billion kilometer science trek to discover the genesis of Jupiter hidden deep inside the planet’s interior. When it arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant.
Questions can be asked during the broadcast via Twitter by using the hashtag #nasajuno -says Slooh. Junoa€™s rocket, the Atlas 551, was only capable of giving Juno enough energy or speed to reach the asteroid belt, at which point the Suna€™s gravity pulled Juno back toward the inner solar system. About two minutes before this point, Juno will pass into Eartha€™s shadow for about 20 minutes.
While the spacecraft may not be visible to the unaided eye, a pair of binoculars or a small telescope with a wide field of view should help. IMPORTANT: you must specify your viewing location in order to see accurate predictions for your area. The Juno team will use this occasion to exercise Junoa€™s science instruments and sample a planetary magnetosphere to get a preview of what to expect from the spacecraft once it arrives at the giant planet.
The trick is to time the flyby so that when Juno returns to Eartha€™s orbital distance, our planet is there.
New Horizons used the same rocket as Juno (the Atlas V 551), however New Horizons was far less massive than Juno, and didna€™t need to stop upon reaching Jupiter.
Eartha€™s point of view is represented on the left, and the suna€™s point of view is represented on the right.
Eartha€™s orbital speed around the Sun can be considered as momentum, which is something that any moving massive object carries (for example, a speeding truck has a lot of momentum). Right-click on the image (control-click on a Mac) and select the option 'Set the Background' or 'Set as Wallpaper' (or similar). Now in its third year of a five-year journey to Jupiter, Juno is about 35 million miles from Earth. This image of Earth (on the left) and the moon (on the right) was taken by NASA's Juno spacecraft on Aug.
It makes one wonder just how many other planets or solar systems might contain life like ours,” Bolton told me. The instrument is working great and in fact, all the instruments that we’ve turned on thus far have been working great,” Bolton added. When she arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant. The spacecraft travels around the Sun, to a point beyond the orbit of Mars where it fires its main engine a couple of times.
24, 2011 nearly 6 million miles distant from Earth visualized by NASA’s Eyes on the Solar System website.
CrowellSeptember 1, 2011 3:15 PMThe velocity is relative to the heliocentric coordinate system. All spacecraft that we send out into the solar system follows more or less this sort of rule.
And even find a reason to defy evolution.I guess i will never understand simple minded people.
On the other hand, non-dogmatic science being what it is, you might do better to embrace the simple truth and harmony of the methodology of physics and the physical sciences.
The Earth flyby gravity assist was planned as part of Junoa€™s trajectory to increase the spacecrafta€™s speed relative to the Sun so that it is sufficient to reach Jupiter. What we learn from Juno will teach us about the early stages of our solar system and how Earth and our neighbor planets formed.


Most of Junoa€™s science instruments have observations planned for the encounter, except for the exquisitely sensitive Microwave Radiometer, which will remain powered off as a protective measure. Once a spacecraft is away from our planet, it is still in orbit around the Sun (just like Earth). Then Juno can use Eartha€™s orbital momentum to increase its own momentum a€“ in effect, stealing a small amount of Eartha€™s orbital energy. Gravity allows the spacecraft to steal a very small bit of our massive, moving planeta€™s great momentum. Both of these components change during a gravity assist to produce a new course, and it is easiest to see each effect by looking at the flyby from two different frames of reference. The spacecrafta€™s direction, but not speed relative to Earth, will similarly be altered by the gravity assist.
When a spacecraft flies closely past the moving planet, the planeta€™s tug on the spacecraft has a profound effect.
As the spacecraft moved eastward during its flyby, the Chilean coast and the snowy line of the Andes Mountains recedes toward the limb at left on the planet.
On the left is an image from the nadir (vertical pointing) camera, which shows the central portion of Nepartak and the storm's eye.
This October, the spacecraft will increase its velocity by 16,330 mph (7.3 kilometers per second) when it makes a flyby of Earth and comes within 347 mile of our planet. The spacecraft snapped the portrait with the onboard JunoCam camera on August 26 after journeying some 6 million miles (9.66 million km) from Earth and while traveling at a velocity of 77,600 miles per hour (124,900 kilometers per hour) relative to the sun. These deep space maneuvers set up the Earth flyby maneuver that occurs approximately two years after launch. Ken has presented at numerous educational institutions, civic & religious organizations, museums and astronomy clubs.
Scott Bolton of Southwest Research Institute® is the Juno mission principal investigator, leading an international science team seeking to answer some fundamental questions about the gas giant and, in turn, about the processes that led to formation of our solar system. Viewers in other parts of the world, including the United States, might be able to image the spacecraft using a telescope the evening following the flyby, as a faint object moving against the background stars.
The velocity or speed of an orbit around the Sun dictates the distance an object can reach with respect to the Sun. Chemical propulsion provided by Junoa€™s launch vehicle gave the spacecraft a bit more than half the boost it needs to get to Jupiter; the Earth flyby provides the rest.
6 at 3:18 UTC) when Juno was at a distance of about 195,000 miles (314,000 kilometers) from Earth. The velocity of the spacecraft is of course not oriented along the Earth’s orbital velocity. It would take a more powerful rocket to send a spacecraft as massive and capable as Juno directly to Jupiter.
Because Juno has much less mass compared to Earth, this small amount of momentum results in a relatively large boost to Juno.
The images were taken remotely by amateur astronomer Scott Ferguson using Global Rent-a-Scope's GRAS-016 Takahashi Widefield Refractor, which is located in Nerpio, Spain.
In framing turn, what is that large measure of space ( the Sun’s domain of light-hours ) in comparison to the enormous expanse of our ancient star-strewn Galaxy?
It takes about two years for the Juno spacecraft to travel around the sun once and come back to Earth for the flyby, and then three more years to coast out to Jupiter. The Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala.
I know the Juno Cam is mostly for PR to reach out to the public, but I can’t wait myself for the images to come in.
Hopefully it will allow a look down that reveals the different layer decks, something akin to what you can see on certain occassions from an airliner.
