Answer: The Mach number represents the ratio between the speed of the airflow encountering a vehicle and the speed of sound.Unfortunately, this is a known issue with the KML language, and there is no way to prevent your balloon from closing.Ī 3D model of the space shuttle approaches the runway in Google Earth. Answer: Whenever Google Earth refreshes to get the latest data, it automatically closes all balloons.When I click on the colored markers to read the balloon, it closes after a few seconds.Select the “Auto-Follow” option in the Places pane on the left side of the screen. You can let Google Earth automatically follow the Space Shuttle as it flies.I am not comfortable navigating in Google Earth.Answer: Select the Manual Control option in the Places pane on the left side of the screen in Google Earth.This means it will take a few seconds before it will reach your computer. Answer: Typically, the data is 5-10 seconds behind real time.How old is the data before I see it on my computer?.A subset of this data is processed and published as a KML file which is readable by Google Earth. Answer: As the space shuttle flies, it sends down data to NASA’s Mission Control Center to ground stations and the Tracking and Data Relay Satellite System (TDRSS) to keep flight controllers updated on the space craft's systems.Right-click on either Manual Control or Auto-Follow, and click "Refresh" from the dropdown menu.If you see a red circle, it means that it has encountered an error.If you see a yellow circle in front of the folder, it is currently refreshing its data.If you see a green circle in front of the folder, you have the most up-to-date data.Check the folder icon ("Auto-Follow" or "Manual Control").The shuttle is not moving (not updating).If you are in Manual Mode, you can double click "Manual Control" in the Places pane, and it will bring you to the current position of the orbiter. If you are currently in Auto-Follow mode, Google Earth will automatically zoom to the shuttle. Answer: Check if you have selected Auto-Follow or Manual Mode.I can’t find the space shuttle on the map.› Short Ascent Preview | › Long Ascent Preview | › Entry Preview If you click on the colored dots along the trajectory, a balloon will open to display information about the shuttle's flight at that point in the trajectory. This enables users that are already comfortable with Google Earth's navigation controls to pan and zoom to whatever view they desire. It will not automatically follow the Space Shuttle. Manual Control lets the user control the view within Google Earth. This is recommended for passively monitoring the launch/landing ("set it and forget it") or if you are not familiar with navigating in Google Earth. During the dynamic launch and entry phases of flight, normally the view is set to a Chase View or Low View. There are two viewing options: Auto-Follow (default) and Manual Control.Īuto-Follow will automatically move with the space shuttle as it launches/lands. Mission events are shown as colored dots on the yellow line when and where they occurred. It represents the path that the shuttle has flown so far. The space shuttle trajectory - the path that the vehicle flies - is shown as a yellow line. Google Earth displays the world in 3D with satellite imagery, and you can also visualize geospatial data. Using live shuttle data, a 3D model of NASA’s space shuttle is plotted in Google Earth to show its current position and trajectory. Select the "Open" option, and the file will automatically open in Google Earth, if you have it installed. You will be prompted to save/open the file. Don’t have Google Earth? Download it here.Īfter you have installed Google Earth, download the live groundtrack file here or a replay of the STS-135 ascent. You will need Google Earth to use this file. You can now track the space shuttle during launch and landing in Google Earth using real-time data from Mission Control. A 3D model of the space shuttle ascends in Google Earth.
