  • Weighing Uranus' Moon Cressida with the Η Ring

Weighing Uranus’ Moon Cressida with the η Ring Robert O. Chancia1 , Matthew M. Hedman1 , and Richard G. French2 1 Department of Physics, University of Idaho, Moscow, ID 83844-0903, USA; [email protected] 2 Astronomy Department, Wellesley College, Wellesley, MA 02481, USA Received 2017 June 19; revised 2017 August 9; accepted 2017 August 21; published 2017 September 20 Abstract The η ring is one of the narrow rings of Uranus, consisting of a dense core that is 1–2 km wide and a diffuse outer sheet spanning about 40 km. Its dense core lies just exterior to the 3:2 Inner Lindblad Resonance of the small moon Cressida. We fit the η ring radius residuals and longitudes from a complete set of both ground-based and Voyager stellar and radio occultations of the Uranian rings spanning 1977–2002. We find variations in the radial position of the η ring that are likely generated by this resonance, and take the form of a 3-lobed structure rotating at an angular rate equal to the mean motion of the moon Cressida. The amplitude of these radial oscillations is 0.667±0.113 km, which is consistent with the expected shape due to the perturbations from Cressida. The magnitude of these variations provides the first measurement of the mass and density of the moon Cressida (m =´()2.5 0.4 1017 kg and r =0.86 0.16 gcm−3) or, indeed, any of Uranus’ small inner moons.

  • The Right Rocket for the Job: Small Launch Providers Target Small Satellites
    The Right Rocket for the Job: Small Launch Providers Target Small Satellites An STS Research Paper presented to the faculty of the School of Engineering and Applied Science University of Virginia by Gabriel Norris May 11, 2020 On my honor as a University student, I have neither given nor received unauthorized aid on this assignment as defined by the Honor Guidelines for Thesis-Related Assignments. Signed: _________________________________________________ Approved: _______________________________________ Date ________________________ Peter Norton, Department of Engineering and Society 2 The University of Virginia Department of Mechanical and Aerospace Engineering has its first satellite, Libertas, now in orbit and plans to launch two more within the next three years. This sudden activity is representative of the vastly increased smallsat1 launch cadence by a variety of groups around the world. The trend is facilitated by the reduced cost and relative ease of assembly conferred by CubeSats, which collectively make up 70 percent of satellites launched today (Halt & Wieger, 2019). Startups, underdeveloped countries, and universities that, just ten years ago, would have been incapable of any kind of space mission are now launching several. From 2012 to 2019, 663 CubeSats were manufactured by private companies, nearly 300 by governments or militaries, and 371 by academic institutions. Yearly satellite launches have increased six-fold in this time (Halt & Wieger, 2019; fig. 1). This marked increase in customers underscores a sociotechnical problem in the rocketry industry: most rockets are fairly large and cater primarily to large satellites, leaving behind a large number of customers in the smallsat domain. Satellites broadly fall within four categories of use: remote sensing, communication, technology demonstration, and scientific investigation.

  • By: Maddie S. It Takes 84 Earth Years for It to Complete One Orbit
    Uranus By: Maddie S. It takes 84 earth years for it to complete one orbit. It's radius is 400.1 miles. At its closest it orbits Uranus appeared to be 1.7 billion miles away. At its only a blue-green ball with farthest it orbits 1.9 billion miles a smooth surface. away. Uranus is too far away to see easily without a telescope. Uranus is the seventh planet Sometimes it is just bright from the sun. It orbits farther enough to see with the naked out, along Uranus's outer eye. ring. Uranus' high powered telescope at the Keck Observatory in Hawaii creates detailed images of Uranus. Each of Uranus' hemispheres receives 42 earth years of sunlight. Uranus' rings are a mix of large chunks of matter and fine particles of dust. One spacecraft has managed to visit Uranus but it took a little creativity to get it there. The rings orbiting Uranus are thinner than those orbiting other planets. Uranus has ten moons. Ariel is Uranus's brightest moon. The moons names are Juliet, Puck Cordelia, Ophelia, Bianca, Desdemona, Portia, Rosalind, Cressida, and Belinda. Umbriel is the darkest moon on Uranus. Uranus Uranus is so far away that for about 200 years scientists could not make out how quickly it turns on its axis. Most planets turn on their axis in such a way that they are almost upright as they move about the sun. It is the only planet with an axis tipped that way, so some think of it as a sideways planet. Like most planets, Uranus has its own natural satellites, or moons.
