NASA's Juno spacecraft loops into orbit around Jupiter

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - NASA'S Juno spacecraft capped a five-year journey to Jupiter on Monday with a do-or-die engine burn that looped it into orbit to probe the origins of the biggest planet in the solar system and how it impacted the rise of life on Earth, the U.S. space agency said. Juno fired its main engine for 35 minutes beginning at 11:18 a.m. EDT/0318 Tuesday GMT, slowing the spacecraft so it could be captured by the planet's gravity.     Once in position to begin its 20-month science mission, Juno will fly in egg-shaped orbits, each one lasting 14 days, to learn if Jupiter has a dense core beneath its clouds and map its massive magnetic field. The probe also will hunt for water in Jupiter's thick atmosphere, a key yardstick for figuring out how far away from the sun the gas giant formed.

Fastest-Ever Spacecraft to Arrive at Jupiter Tonight

NASA's Juno probe will attempt to slip into orbit around Jupiter tonight (July 4), shortly after becoming the fastest object ever made by human hands. As Juno nears Jupiter tonight, the giant planet's powerful gravity will accelerate the spacecraft to an estimated top speed of about 165,000 mph (265,000 km/h) relative to Earth, mission team members said. "I don't think we've had any human[-made] object that's moved that fast, that's left the Earth," Juno principal investigator Scott Bolton, of the Southwest Research Institute in San Antonio, said during a news conference last week.

NASA's Juno spacecraft poised for one-shot try to orbit Jupiter

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A NASA spacecraft was poised for a one-shot attempt to slip into Jupiter's orbit on Monday for the start of a 20-month-long dance around the solar system’s largest planet to learn how and where it formed. Flight controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California, were preparing for a long night as the Juno probe streaked closer toward Jupiter at 200 times the speed of sound in the empty vacuum of space. Confirmation of whether Juno, the only solar-powered spacecraft ever dispatched to the outer solar system, had successfully placed itself into polar orbit around Jupiter was not expected until 11:53 p.m. EDT on Monday (0353 GMT on Tuesday).
