Nasa Jupiter Probe

Nasa Jupiter Probe, A trip to Jupiter begins today, when NASA plans to launch an ambitious probe to reveal the interior of the largest planet in the solar system.
The 1.1 billion and will reach Jupiter Juno mission in 2016, where the spacecraft solar power have to hit a precise orbit about the planet’s poles. Mission controllers at NASA’s Kennedy Center on Wednesday approved the release of 11:34 a.m. ET today, although there was a 30% chance of rain would force a delay.
“All systems are ready to go,” said Jan Chodas of the Jet Propulsion Laboratory in Pasadena, California, at a conference.
After its launch aboard an Atlas V rocket, the most powerful rocket in the inventory following the retirement of NASA space shuttle, the vessel of 8,000 pounds will feature three 29-foot long solar panels to supply energy to Jupiter five times farther from the Sun than Earth.
“We are getting closer to Jupiter than any spacecraft has gone,” said mission chief scientist Scott Bolton of Southwest Research Institute in San Antonio.
Juno will travel through the poles of Jupiter, only 3100 miles above the clouds and below the belts of radiation. “We’re just skimming the clouds,” says Bolton.
A NASA probe has orbited Jupiter since the Galileo mission ended in 2003, a trip that focused both on the moons of Jupiter as the planet itself. Juno instead, seek answers to the origin of Jupiter, and if the cloud swirling world has a solid core, says Bolton, “or if it’s just the gas to the bottom.”
Juno will also try to measure the depth of the famous Jupiter “Red Spot”, a huge storm like a hurricane more than 15,000 miles wide.
To pierce the veil of Jupiter, the spacecraft will rotate around the poles of the planet 30 times in the observation of 11 days on a mission of one year, says Chodas. Due to the very strong magnetic field of Jupiter, 14 times stronger than the Earth, the planet’s radiation belts have to destroy the spacecraft electronics, which require strong titanium shield computers from Juno. “We are basically an armored tank to go to Jupiter,” says Bolton.
Jupiter is a “gas giant”, composed primarily of hydrogen and helium sweep the dawn of the solar system about 4.6 billion years. That he was weighing all the other planets of the solar system combined 3 to 1 and weighs 318 times more than Earth. Astronomers want to know more about their origins because of its dominant role in our solar system and because most of the approximately 500 planets detected orbiting nearby stars since 1995 are believed to be gas giants similar.
