In the past few billion years, Earth has been pummeled by asteroids, crashed into other planets and frozen over several times. Not to mention being ruled by all kinds of crazy lifeforms. 00:00 Earth's Evolution in 10 Minutes 00:37 4.5 BILLION YEARS AGO 02:25 3.8 BILLION YEARS AGO 03:16 3.3 BILLION YEARS AGO 03:47 2.4 BILLION YEARS AGO 04:29 1.1 BILLION YEARS AGO 06:22 250 MILLION YEARS AGO 07:33 66 MILLION YEARS AGO 08:03 6 MILLION YEARS AGO

How do spacecraft slow down? Rigid heat shields and retropropulsion have been the favorites of engineers for years. Now NASA is testing a new inflatable heat shield technology that could allow us to carry even larger payloads to worlds with atmospheres: https://www.nasa.gov/loftid Launching on Nov. 1 aboard a United Launch Alliance Atlas V rocket along with NOAA’s JPSS-2 mission, the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, will demonstrate the heat shield’s ability to slow down and survive atmospheric entry: https://go.nasa.gov/3N7yzBG Producers: Scott Bednar, Jessica Wilde Editor: Daniel Salazar Credit: NASA #NASA #Technology #Spacecraft

On August 21, 2017, a continent-spanning wave of instruments from home-made pinhole cameras to the most sophisticated telescopes in operation today will be trained on the Eclipse Across America. eclipse2017.nasa.gov

A new Earth science mission, led by NASA and the French space agency Centre National d’Études Spatiales (CNES), will help communities plan for a better future by surveying the planet’s salt and freshwater bodies. The Surface Water and Ocean Topography (SWOT) mission will measure the height of water in lakes, rivers, reservoirs, and the oceans. As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to improve flood forecasts and monitor drought conditions, providing essential information to water management agencies, civil engineers, universities, the U.S. Department of Defense, disaster preparedness agencies, and others who need to track water in their local areas. In this video, examples of how SWOT data will be used in these communities are shared by a National Weather Service representative in Oregon, an Alaska Department of Transportation engineer, researchers from the University of Oregon and University of North Carolina, a NASA Jet Propulsion Laboratory scientist working with the Department of Defense, and a JPL scientist working with the Louisiana Coastal Protection and Restoration Agency. :30 - Flood Watches & Warnings - Portland, Oregon 1:08 - Water Management - Fern Ridge Lake, Oregon 2:05 - Protecting Infrastructure - Alaska 2:54 - National Security - Department of Defense 3:24 - Coastal Protection - Mississippi River Delta SWOT is expected to launch from Vandenberg Space Force Base in California in December 2022. The mission is a collaboration between NASA and CNES, with contributions from the Canadian Space Agency and UK Space Agency. JPL, which is managed for NASA by Caltech in Pasadena, California, leads the U.S. component of the project.
