A satellite this small and this close to the asteroid could not be resolved in the available VLT adaptive optics observations of Agamemnon recorded in 2003. -

Binary and Multiple Systems of Asteroids
Binary and Multiple Systems Andrew Cheng1, Andrew Rivkin2, Patrick Michel3, Carey Lisse4, Kevin Walsh5, Keith Noll6, Darin Ragozzine7, Clark Chapman8, William Merline9, Lance Benner10, Daniel Scheeres11 1JHU/APL [[email protected]] 2JHU/APL [[email protected]] 3University of Nice-Sophia Antipolis/CNRS/Observatoire de la Côte d'Azur [[email protected]] 4JHU/APL [[email protected]] 5University of Nice-Sophia Antipolis/CNRS/Observatoire de la Côte d'Azur [[email protected]] 6STScI [[email protected]] 7Harvard-Smithsonian Center for Astrophysics [[email protected]] 8SwRI [[email protected]] 9SwRI [[email protected]] 10JPL [[email protected]] 11Univ Colorado [[email protected]] Abstract A sizable fraction of small bodies, including roughly 15% of NEOs, is found in binary or multiple systems. Understanding the formation processes of such systems is critical to understanding the collisional and dynamical evolution of small body systems, including even dwarf planets. Binary and multiple systems provide a means of determining critical physical properties (masses, densities, and rotations) with greater ease and higher precision than is available for single objects. Binaries and multiples provide a natural laboratory for dynamical and collisional investigations and may exhibit unique geologic processes such as mass transfer or even accretion disks. Missions to many classes of planetary bodies – asteroids, Trojans, TNOs, dwarf planets – can offer enhanced science return if they target binary or multiple systems. Introduction Asteroid lightcurves were often interpreted through the 1970s and 1980s as showing evidence for satellites, and occultations of stars by asteroids also provided tantalizing if inconclusive hints that asteroid satellites may exist. -

1 Rotation Periods of Binary Asteroids with Large Separations
Rotation Periods of Binary Asteroids with Large Separations – Confronting the Escaping Ejecta Binaries Model with Observations a,b,* b a D. Polishook , N. Brosch , D. Prialnik a Department of Geophysics and Planetary Sciences, Tel-Aviv University, Israel. b The Wise Observatory and the School of Physics and Astronomy, Tel-Aviv University, Israel. * Corresponding author: David Polishook, [email protected] Abstract Durda et al. (2004), using numerical models, suggested that binary asteroids with large separation, called Escaping Ejecta Binaries (EEBs), can be created by fragments ejected from a disruptive impact event. It is thought that six binary asteroids recently discovered might be EEBs because of the high separation between their components (~100 > a/Rp > ~20). However, the rotation periods of four out of the six objects measured by our group and others and presented here show that these suspected EEBs have fast rotation rates of 2.5 to 4 hours. Because of the small size of the components of these binary asteroids, linked with this fast spinning, we conclude that the rotational-fission mechanism, which is a result of the thermal YORP effect, is the most likely formation scenario. Moreover, scaling the YORP effect for these objects shows that its timescale is shorter than the estimated ages of the three relevant Hirayama families hosting these binary asteroids. Therefore, only the largest (D~19 km) suspected asteroid, (317) Roxane , could be, in fact, the only known EEB. In addition, our results confirm the triple nature of (3749) Balam by measuring mutual events on its lightcurve that match the orbital period of a nearby satellite in addition to its distant companion. -

INTRODUCTION of an asteroid prior to impact, or from asteroid fragments dispersed by aerodynamic forces during entry. We propose that Two commonly held paradigms about asteroids and some fast rotating rubble-pile asteroids (e.g., 4769 Castalia), comets are that (a) they are composed of non-fragmented after experiencing a close approach with a planet, undergo tidal chunks of rock or rock/ice mixtures, and (b) they are soli- breakup and split into multiple co-orbiting fragments. -
STS-132 Mission Summary
NASA Mission Summary National Aeronautics and Space Administration Washington, D.C. 20546 (202) 358-1100 STS-132 MISSION SUMMARY May 2010 SPACE SHUTTLE ATLANTIS Atlantis’ 12-day mission will deliver the Russian-built Mini Research Module-1 that will provide additional storage space and a new docking port for Russian Soyuz and Progress spacecraft. MRM-1, also known as Rassvet, which means dawn in Russian, will be permanently attached to the bottom port of the station’s Zarya module. MRM-1 will carry important hardware on its exterior including a radiator, airlock and a European robotic arm. Atlantis also will deliver addi- tional station hardware stored inside a cargo carrier. Three spacewalks are planned to stage spare components outside the station, including six spare batteries, a Ku-band antenna and spare parts for the Canadian Dextre robotic arm. Shuttle mission STS-132 is the final sched- uled flight for Atlantis .

Rule Number 7 of the 365 Days of Astronomy Podcast States The
Hi this is Steve Nerlich from Cheap Astronomy www.cheapastro.com and this is Finishing the ISS. The clock is ticking with only five more Space Shuttle launches confirmed to complete – at least the USA’s contribution to – the International Space Station. This podcast is about how all that will happen – and what happens then. Commenced in 1998, the construction of the ISS was sadly interrupted with the destruction of the Columbia orbiter in mission STS 107 in February 2003 – followed by a subsequent two year hiatus while the Space Shuttle program was reconfigured. Of course the Russians have done their bit keeping the station manned and flying before and after the Columbia disaster – as well as contributing some important components, including the original Zarya module that started it all, the Zvezda, the Pirs – and just a couple of weeks ago, on the 12th of November 2009, the Poisk. Other international players have also got their modules in place now, with the European Columbus module delivered in February 2008 and the Japanese Kibo module in May 2008. As of today, the ISS is 108 by 73 by 20 metres and weighs over 300 metric tonnes. It is composed of 10 pressurised modules and a huge Integrated Truss Structure supporting 16 large solar arrays in addition to four smaller arrays on some of the Russian modules. With all the planned solar arrays now in place the ISS has become brighter than Venus and replaces it as the second brightest object in the night sky after the Moon. The recent launch of STS 129 in November 2009 represents the 31st visit of a space shuttle to the ISS and brings up two Express Logistics Carriers – Express is an acronym for Expedite the Processing of Experiments to the Space Station.
