Celestia 1.6.1 for Mac
Celestia 1.6.1 for Mac The free space simulation that lets you explore our universe in three dimensions. Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy. All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit. Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy to install add-ons with more objects. Changelog: Bug fixes * Removed extraneous colons from nearstars.stc * Fixed truncation of long label strings in East Asian locales * Increased size of Goto Object dialog to prevent translated strings from being truncated * Fixed i18n bug with scripting message * Removed duplicate install of stars.dat. * Fix code taking address of a temporary result. * Fixed compile warnings in 1.6.1 caused by redfinition of UINT64_MAX * Corrected encoding of cel URLs with non-ASCII characters * Added check to prevent a crash when string decoding fails Data file updates: * Updated extrasolar planets data files. * Updated solar system locations files. * Updated numberedmoons.ssc file. * Updated Galileo add-on. Platform-specific changes: * Linux: Add missing files from extras-standard to Makefiles. * Windows: Fixed i18n bug [2753461] * Windows: Save FoV value in bookmarks * Windows: Added ecliptic line setting to View Options dialog box * Windows: Fixed i18n bug in Windows Script menu * Windows: Added link to new HTML help files to Help menu * Windows: Fixed invisible context menu in fullscreen mode (ATI cards) * Windows: Fixed menu bar overlapping top of 3D view (ATI cards) * Windows: Save and restore locations to/from ...

Microsoft Worldwide Telescope (WWT) 5.2.9
Microsoft Worldwide Telescope (WWT) 5.2.9 The WorldWide Telescope (WWT) is a visualization environment that enables your computer to function as a virtual telescope—bringing together imagery from the world’s best ground- and space-based telescopes for the exploration of the universe. WWT blends terabytes of images, information, and stories from multiple sources into a seamless, immersive, rich media experience. Explorers of all ages will feel empowered to explore and understand the cosmos using WWT’s simple and powerful user interface. The mission of the WorldWide Telescope is twofold: To aggregate scientific data from major telescopes, observatories, and institutions and make temporal and multi-spectral studies available through a single, cohesive Internet–based portal To stimulate interest in science among younger generations, providing a compelling base for teaching astronomy, scientific discovery, and computational science WorldWide Telescope is dedicated to the memory of Jim Gray. It is a free, open-source resource to the astronomy and education communities with the hope that it will inspire and empower people to explore and understand the universe like never before. Version 5.2 runs on Windows 7 or Windows 8, in either 32- or 64-bit mode, depending on your operating system. It also supports native DirectX 11, DirectX 10, and has some support for down-level DirectX 9 hardware running through the DirectX 11 API. WWT 5.2 System Requirements To run this software, you need the following on your computer: Windows 7 or Windows 8 (older versions of Windows are not supported) Discrete graphics card with 512 MB VRAM, DirectX 10 or DirectX 11 compatibility, high-end GTX 480 class or better, and 1 GB VRAM recommended WorldWide Telescope 5.2 Microsoft .NET Framework 4.5.1 Do not attempt to install WWT 5.2 on Windows XP. It does not run and can potentially prevent ...

RASAero II 1.0.1.0
RASAero II 1.0.1.0 RASAero II is a combined aerodynamic analysis and flight simulation software package for model rockets and high power rockets, amateur rockets, and sounding rockets. RASAero II can also be used for predicting aerodynamic coefficients for use in other flight simulation programs for orbital rockets. The RASAero II aerodynamic prediction methods are the most accurate available for model, high power, and amateur rockets, and are of equivalent accuracy to professional engineering method aerodynamic analysis codes used for missiles, sounding rockets, and space launch vehicles. In testing in comparison with high power rocket barometric altimeter data, optical tracking data, accelerometer-based flight data, and GPS flight data, the average RASAero II altitude prediction error was 3.38%, with 78.8% of the RASAero II flight simulation altitude predictions within +/- 10% of the flight data, and 42.4% of the altitude predictions within +/- 5% of the flight data. The RASAero II aerodynamic predictions include drag coefficient at zero degrees angle of attack, drag coefficient with a non-zero angle of attack, and lift coefficient and normal force coefficient with angle of attack; for both power-on (thrust phase) and power-off (coast phase). Center of pressure is predicted both as a function of Mach number and as a function of angle of attack. Aerodynamic coefficients are predicted for the subsonic, transonic, supersonic, and hypersonic flight regimes, from Mach 0.01 to Mach 25. The RASAero II aerodynamic prediction methods and the RASAero II software have been calibrated against NACA and NASA wind tunnel model data, free-flight model data and sounding rocket data, missile aerodynamic data, and professional engineering method missile aerodynamic analysis programs, against which in comparison tests RASAero II has demonstrated equivalent numerical accuracy. RASAero II release history: Version 1.0.1.0 – Release Date August 5, 2016 Changed the recommended stability margin for subsonic Mach ...
