Delays the next stage of the mission of the Juno probe. The mission control center took the decision to transfer is scheduled for Wednesday maneuvers, correcting the orbit of the probe. The start of the main engine of the probe was to decrease its orbital period around Jupiter from 53.4 to 14 days. NASA said, however, that need more time to analyze observed yesterday, irregularities in the operation of the valves, the fuel. Another possibility to correct orbit will have during the next approach to Jupiter on December 11.

by the way maneuver PRM (period reduction maneuver) the main engine of the probe is included in the latest times. During testing appeared, however, worrying signals related to the operation of the valves, seal installation helową. telemetry Data show that two non-return valve, which will play an important role during startup of the engine, didn’t work at all after the initialization command sequence, says Rick Nybakken of the Jet Propulsion Laboratory in Pasadena. Valves must be open for a few seconds, it took them a few minutes. Before we decide to start the main engine, we need to better understand what happened, he added.
the Probe wanders Juno is currently in a highly elliptical orbit and is approaching Jupiter. The best time to perform such a maneuver is necessary at the time of maximum approach to the planet. After the rejection of the echoes deadline, the next opportunity will appear on 11 December. After successfully passing near Jupiter on August 27, NASA planned that most of the research instrument probe will be disabled. If the maneuver PRM will not, the scientists used the flight to gather more data.
maturity does not affect the quality of data collected during closest approach to Jupiter, says Scott Bolton of the Southwest Research Institute in San Antonio. the Mission is very flexible. Data collected during the trip on August 27 was a real revelation, I am convinced that October 19 will be the same, he added.

the photo Above, Juneau made on 27 August from a distance of about 195000 miles from the center of Jupiter, about two hours prior to rapid convergence. The largest planet in our Solar System we have not seen from this point of view, from time to time, when the probe Pioneer 11 passed in 1974. The photo shows the formation of clouds not seen until now none of the gas giants in our solar system.
during the first of 36 planned community of the Jupiter probe was at a minimum distance of 4200 kilometres from the upper surface of its clouds. After 6 hours I collected about 6 MB of data which is the message to Earth, then took about a day and a half. <>First look at the North pole has shown that have never been seen, he said in early September, Bolton.
