The Solar System
5 The Solar System R. Lynne Jones, Steven R. Chesley, Paul A. Abell, Michael E. Brown, Josef Durech,ˇ Yanga R. Fern´andez,Alan W. Harris, Matt J. Holman, Zeljkoˇ Ivezi´c,R. Jedicke, Mikko Kaasalainen, Nathan A. Kaib, Zoran Kneˇzevi´c,Andrea Milani, Alex Parker, Stephen T. Ridgway, David E. Trilling, Bojan Vrˇsnak LSST will provide huge advances in our knowledge of millions of astronomical objects “close to home’”– the small bodies in our Solar System. Previous studies of these small bodies have led to dramatic changes in our understanding of the process of planet formation and evolution, and the relationship between our Solar System and other systems. Beyond providing asteroid targets for space missions or igniting popular interest in observing a new comet or learning about a new distant icy dwarf planet, these small bodies also serve as large populations of “test particles,” recording the dynamical history of the giant planets, revealing the nature of the Solar System impactor population over time, and illustrating the size distributions of planetesimals, which were the building blocks of planets. In this chapter, a brief introduction to the different populations of small bodies in the Solar System (§ 5.1) is followed by a summary of the number of objects of each population that LSST is expected to find (§ 5.2). Some of the Solar System science that LSST will address is presented through the rest of the chapter, starting with the insights into planetary formation and evolution gained through the small body population orbital distributions (§ 5.3). The effects of collisional evolution in the Main Belt and Kuiper Belt are discussed in the next two sections, along with the implications for the determination of the size distribution in the Main Belt (§ 5.4) and possibilities for identifying wide binaries and understanding the environment in the early outer Solar System in § 5.5. -
Meteoroid Stream Formation Due to the Extraction of Space Resources from Asteroids
Meteoroid Stream Formation Due to the Extraction of Space Resources from Asteroids Logan Fladeland(1), Aaron C. Boley(2), and Michael Byers(3) (1) UBC, Department of Physics and Astronomy, 6224 Agricultural Rd, Vancouver, BC V6T 1Z1 (Canada), [email protected] (2) UBC, Department of Physics and Astronomy, 6224 Agricultural Rd, Vancouver, BC V6T 1Z1 (Canada), [email protected] (3) UBC, Department of Political Science, 1866 Main Mall C425, Vancouver, BC V6T 1Z1 (Canada), [email protected] ABSTRACT Asteroid mining is not necessarily a distant prospect. Building on the earlier mission Hayabusa, two spacecraft (Hayabusa2 and OSIRIS-REx) have recently rendezvoused with near-Earth asteroids and will return samples to Earth. While there is significant science motivation for these missions, there are also resource interests. Space agencies and commercial entities are particularly interested in ices and water-bearing minerals that could be used to produce rocket fuel in deep space. The internationally coordinated roadmaps of major space agencies depend on utilizing the natural resources of such celestial bodies. Several companies have already created plans for intercepting and extracting water and minerals from near-Earth objects, as even a small asteroid could have high economic worth. The low surface gravity of asteroids could make the release of mining waste and the subsequent formation of debris streams a consequence of asteroid mining. Proposed strategies that would contain material during extraction could be inefficient or could still require the purposeful jettison of mining waste to avoid the need to manage unwanted mass. Since all early mining targets are expected to be near-Earth asteroids due to their orbital accessibility, these streams could be Earth-crossing and create risks for Earth and lunar satellite populations, as well as humans and equipment on the lunar surface. -
Meteor Showers' Activity and Forecasting
Meteoroids 2007 – Barcelona, June 11-15 About the cover: The recent fall of the Villalbeto de la Peña meteorite on January 4, 2004 (Spain) is one of the best documented in history for which atmospheric and orbital trajectory, strewn field area, and recovery circumstances have been described in detail. Photometric and seismic measurements together with radioisotopic analysis of several recovered specimens suggest an original mass of about 760 kg. About fifty specimens were recovered from a strewn field of nearly 100 km2. Villalbeto de la Peña is a moderately shocked (S4) equilibrated ordinary chondrite (L6) with a cosmic-ray-exposure age of 48±5 Ma. The chemistry and mineralogy of this genuine meteorite has been characterized in detail by bulk chemical analysis, electron microprobe, electron microscopy, magnetism, porosimetry, X-ray diffraction, infrared, Raman, and 57Mössbauer spectroscopies. The picture of the fireball was taken by M.M. Ruiz and was awarded by the contest organized by the Spanish Fireball Network (SPMN) for the best photograph of the event. The Moon is also visible for comparison. The picture of the meteorite was taken as it was found by the SPMN recovery team few days after the fall. 2 Meteoroids 2007 – Barcelona, June 11-15 FINAL PROGRAM Monday, June 11 Auditorium conference room 9h00-9h50 Reception 9h50-10h00 Opening event Session 1: Observational Techniques and Meteor Detection Programs Morning session Session chairs: J.

Meteor- Scatter
Catch a Falling Star A beginner’s guide to meteor-scatter communication— just in time for “stormy” weather! By Kirk Kleinschmidt, NT0Z Newcomers to Amateur Radio usually have a few misconceptions about VHF propagation. The worst—which is often “propagated” by more experienced hams who should know better—suggests that VHF signals travel exclusively along line-of-sight paths and peter out after about 30 miles. That’s far from true, but if your VHF operation is limited to 2-meter FM it’s somehow practical, especially if you’re using a hand-held radio and a rubber ducky antenna. Once you cross the “30-mile barrier,” however, there are many exciting and interesting ways to propagate your VHF signal hundreds or even thousands of kilometers. Articles in the ARRL Operating Manual and QST detail E- and F-layer skip, tropospheric ducting and transequatorial field-aligned irregularities, moon-bounce, auroral propagation and others. These modes aren’t always casual. That is, many require robust stations, high power and more than a little patience. Meteor- scatter work—bouncing radio signals off the ionized trails produced by meteors burning through the ionosphere—doesn’t require an extraordinary station, but some patience is usually necessary unless you know exactly when conditions may be favorable! That’s precisely the case with the November Leonids meteor showers for the next few years. (Meteor showers are named for the constellations from which they seem to appear. Meteors produced during the recurring November 17 shower seem to “pour” from the constellation Leo.) As an added bonus, on one or more of those November days the short-duration, high-intensity Leonids have the potential to produce the best meteor-scatter propagation since November 1966 (and a spectacular light show if you’re on the night side of the planet!). -

Tessellation and Miura Folds MINUTES
15-30 Tessellation and Miura Folds MINUTES Materials › 1+ sheets of A4 paper (210 x 297 mm) › A ruler › Coloured pens (optional) › A protractor Activity Overview › Learn how to create your own Miura folds (method of folding a flat surface, such as a sheet of paper, into a smaller area). The fold is named after its inventor, Japanese astrophysicist Koryo Miura. Use a simple piece of paper before reverse engineering your own design for a different sized piece of paper with your own observations. › Activity from: https://www.sciencefriday.com/educational-resources/tessellation-and- miura-folds/ Activity Plan › Fold the paper into five evenly spaced sections, alternating mountain and valley folds to create an accordion fold – also called a concertina fold. Mountain Fold Valley Fold Use a ruler when folding to get a sharp, straight line Pattern of mountain and valley folds to create your five columns › Keeping the paper folded (it should look like a tall, thin rectangle), you will create seven more sections by alternating mountain and valley folds. To make the first fold, take the bottom of the paper and fold a section up and at an angle to the left, so that the top left corner is about 4cm from the top of the rest of the paper and 2cm from the left edge of the rest of the paper (see picture A). › Next, fold a portion of the paper that you just folded up, back down so that its front right edge is parallel with the right edge of what remains of the original tall, thin rectangle (pictures B+C). -
