  • 1 the New Horizons Spacecraft Glen H. Fountain, David Y
    The New Horizons Spacecraft Glen H. Fountain, David Y. Kusnierkiewicz, Christopher B. Hersman, Timothy S. Herder, Thomas B Coughlin, William T. Gibson, Deborah A. Clancy, Christopher C. DeBoy, T. Adrian Hill, James D. Kinnison, Douglas S. Mehoke, Geffrey K. Ottman, Gabe D. Rogers, S. Alan Stern, James M. Stratton, Steven R. Vernon, Stephen P. Williams Abstract The New Horizons spacecraft was launched on January 19, 2006. The spacecraft was designed to provide a platform for the seven instruments designated by the science team to collect and return data from Pluto in 2015 that would meet the requirements established by the National Aeronautics and Space Administration (NASA) Announcement of Opportunity AO-OSS-01. The design drew on heritage from previous missions developed at The Johns Hopkins University Applied Physics Laboratory (APL) and other NASA missions such as Ulysses. The trajectory design imposed constraints on mass and structural strength to meet the high launch acceleration consistent with meeting the AO requirement of returning data prior to the year 2020. The spacecraft subsystems were designed to meet tight resource allocations (mass and power) yet provide the necessary control and data handling finesse to support data collection and return when the one way light time during the Pluto fly-by is 4.5 hours. Missions to the outer regions of the solar system (where the solar irradiance is 1/1000 of the level near the Earth) require a Radioisotope Thermoelectric Generator (RTG) to supply electrical power. One RTG was available for use by New Horizons. To accommodate this constraint, the spacecraft electronics were designed to operate on less than 200 W.

  • NASA Finds Neptune Moons Locked in 'Dance of Avoidance' 15 November 2019, by Gretchen Mccartney
    NASA finds Neptune moons locked in 'dance of avoidance' 15 November 2019, by Gretchen McCartney Although the dance may appear odd, it keeps the orbits stable, researchers said. "We refer to this repeating pattern as a resonance," said Marina Brozovi?, an expert in solar system dynamics at NASA's Jet Propulsion Laboratory in Pasadena, California, and the lead author of the new paper, which was published Nov. 13 in Icarus. "There are many different types of 'dances' that planets, moons and asteroids can follow, but this one has never been seen before." Far from the pull of the Sun, the giant planets of the Neptune Moon Dance: This animation illustrates how the outer solar system are the dominant sources of odd orbits of Neptune's inner moons Naiad and gravity, and collectively, they boast dozens upon Thalassa enable them to avoid each other as they race dozens of moons. Some of those moons formed around the planet. Credit: NASA alongside their planets and never went anywhere; others were captured later, then locked into orbits dictated by their planets. Some orbit in the opposite direction their planets rotate; others swap orbits Even by the wild standards of the outer solar with each other as if to avoid collision. system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to Neptune has 14 confirmed moons. Neso, the newly published research. farthest-flung of them, orbits in a wildly elliptical loop that carries it nearly 46 million miles (74 million Orbital dynamics experts are calling it a "dance of kilometers) away from the planet and takes 27 avoidance" performed by the tiny moons Naiad years to complete.
