Magnetic torquing is also used to maintain the satellite spin rate at 1/ 12 revolution per minute. These systems are outgrowths of APL developments for previous satellites, chosen for simplicity and maximum expectation of satisfactory performance in orbit.

    Juno Spacecraft Description

    Juno Spacecraft Description By Bill Kurth 2012-06-01 Juno Spacecraft (ID=JNO) Description The majority of the text in this file was extracted from the Juno Mission Plan Document, S. Stephens, 29 March 2012. [JPL D-35556] Overview For most Juno experiments, data were collected by instruments on the spacecraft then relayed via the orbiter telemetry system to stations of the NASA Deep Space Network (DSN). Radio Science required the DSN for its data acquisition on the ground. The following sections provide an overview, first of the orbiter, then the science instruments, and finally the DSN ground system. Juno launched on 5 August 2011. The spacecraft uses a deltaV-EGA trajectory consisting of a two-part deep space maneuver on 30 August and 14 September 2012 followed by an Earth gravity assist on 9 October 2013 at an altitude of 559 km. Jupiter arrival is on 5 July 2016 using two 53.5-day capture orbits prior to commencing operations for a 1.3-(Earth) year-long prime mission comprising 32 high inclination, high eccentricity orbits of Jupiter. The orbit is polar (90 degree inclination) with a periapsis altitude of 4200-8000 km and a semi-major axis of 23.4 RJ (Jovian radius) giving an orbital period of 13.965 days. The primary science is acquired for approximately 6 hours centered on each periapsis although fields and particles data are acquired at low rates for the remaining apoapsis portion of each orbit. Juno is a spin-stabilized spacecraft equipped for 8 diverse science investigations plus a camera included for education and public outreach.

Earthrise, seen for the first time by human eyes On Christmas Eve 1968 three American astronauts were in orbit around the Moon: Frank Borman, James Lovell, and Bill Anders. The crew of Apollo 8 had been declared by the United Nations to be the ‘envoys of mankind in outer space’; they were also its eyes.1 They were already the first people to leave Earth orbit, the first to set eyes on the whole Earth, and the first to see the dark side of the Moon, but the most powerful experience still awaited them. For three orbits they gazed down on the lunar surface through their capsule’s tiny windows as they carried out the checks and observations prescribed for almost every minute of this tightly-planned mission. On the fourth orbit, as they began to emerge from the far side of the Moon, something happened. They were still out of radio contact with the Earth, but the on- board voice recorder captured their excitement. Borman: Oh my God! Look at that picture over there! Here’s the Earth coming up. Wow, that is pretty! Anders: Hey, don’t take that, it’s not scheduled.
