After nearly five years traveling through space to its destination, NASA's Juno spacecraft will arrive in orbit around Jupiter on July 4, 2016. This video shows a peek of what the spacecraft saw as it closed in on its destination. Jupiter is visible along with the four Galilean moons: Callisto, Ganymede, Europa and Io. The images were taken prior to June 30, 2016, when the JunoCam camera and science instruments were turned off to prepare the spacecraft for the daring orbit insertion maneuver.

It would great to get back to real science instead of apologist debates in science.

Maybe we need a special forum for that junk.

. . . or just clean out Natural Science 301 of specious threads. 300 courses are supposed to be higher level sciences.

YAHOO!! Successful JOI (Jupiter Orbital Insertion) right on time to the second.

I love watching those live streams from NASA and ESA. One kind of feels the tension, just watching those guys, and being aware of all that time and effort.

Agreed - real science is indeed great, cool, interesting, neat, useful, and fun.

What most people don't realize (because it is done so cleverly and stealthily) is how much ideological promotion takes place under the guise of "science".

That ISN'T the case here - well, mostly. JUNO is the result of applied real operational science. Hopefully we will get to learn much that we did not know before.

People get mesmerized by the wonders of space and the achievements of good science and don't even realize the stealth indoctrination that continuously takes place by those of the Materialist faith.

"Junk"? Matters pertaining to the spirit are "junk"? Really?

No The stupid dreck you try to pass of as YEC "science" is junk. Like your latest laughably bad ICR article on mtDNA "proving" a literal Genesis.

Please ignore Jorge in this thread. We have a clean one, let's try to keep it that way.

I found the discussion on the orbit plan to be very interesting ... that first, there are two orbits of 51 days where the craft swings close in to Jupiter, then a series of orbits of 14 days... apparently keeping the craft out of the radiation zone for prolonged periods of time, and giving NASA plenty of time to assess the data, and determine what they want it to do on the next pass.

If somebody knows more about this, that would be an interesting discussion.

Jedidiah is right on! Do not feed the Trolls.

How Juno Will Peer Deep below Jupiter's Roiling Clouds

PASADENA, Calif.—When ground controllers begin powering up the Juno spacecraft’s science instruments on July 6, one of their most important goals will be to get the microwave radiometer up and running. The radiometer is charged with taking water-vapor readings that will help locate Jupiter’s birthplace in the solar system and plumb its atmospheric structure, including the roots of the mysterious Great Red Spot. “This is a totally new concept specifically designed for Jupiter,” says Michael Janssen of the Jet Propulsion Laboratory, the leader of the Microwave Radiometer Team.

Water vapor is a useful tracer of Jupiter’s formation because it contains most of the oxygen present in the giant planet’s atmosphere, and theorists believe oxygen’s abundance depends on how far Jupiter formed from the sun. In the early days of our solar system the tempestuous young sun boiled oxygen and other volatile materials out of the inner system, leaving planets that formed there relatively oxygen-poor. Worlds that coalesced far from the sun, by contrast, incorporated ices laden with those materials, leaving them relatively oxygen-rich. If Juno’s microwave radiometer finds high levels of water vapor in Jupiter’s atmosphere, that would suggest the planet formed farther out from the sun than its present location. This would add to already-abundant circumstantial evidence hinting Jupiter has migrated from its place of origin.

Critically, Juno’s microwave radiometer will not simply survey Jupiter’s cloud tops—instead, it will peer below the ammonia clouds that shroud most of the planet, which are largely transparent to microwaves. What is more, because Jupiter’s microwave emissions vary in wavelength based on the pressure (as well as temperature) of the atmospheric layers where they originate, observations at multiple wavelengths allow researchers to create a cross-section through the atmosphere. Short wavelengths suss out the near-surface layers; longer wavelengths dive deeper. Juno’s radiometer will probe to a depth of about 500 kilometers. It takes a spacecraft to do that because from Earth the longer wavelengths are obscured by the thick swarms of high-energy particles trapped in the potent magnetic fields that wreathe the giant planet.

The instrument is a kind of radio telescope consisting of six antennas of increasing size, each tuned for a specific wavelength from 1.37 centimeters to 50 centimeters. (For comparison, the microwaves in your oven or radiating from your wireless router typically have a wavelength of about 12 centimeters.) The largest antenna takes up an entire side of the hexagonal spacecraft—indeed, it sets the size of the spacecraft. It is a flat aluminum sheet with a five-by-five grid of aluminum panels, which work in harmony to measure the microwaves. Just before 3 p.m. Pacific time on Wednesday, Janssen and his team confirmed that the radiometer had woken up and detected microwaves.
