These are elements of solar architecture. They used windows and skylights for the same reason, as well as to allow for air circulation. Early civilizations around the world positioned buildings to face south to gather heat and light. This surplus of food allowed for denser populations and structured societies. Drying food using sun and wind prevented crops from spoiling. Solar techniques, such as crop rotation, increased harvests. Developed about 10,000 years ago, agriculture had a key role in the rise of civilization. Solar energy is essential to agriculture-cultivating land, producing crops, and raising livestock. While people have not been around that long, they have been using solar energy in a variety of ways for thousands of years. Solar energy has existed as long as the sun-about 5 billion years. There would be no winds, ocean currents, or clouds to transport water. Without heat from the sun, Earth would freeze. Animals, including humans, need plants for food and the oxygen they produce. It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Even at a distan ce of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit.

In this case, both satellites will deliver satellite TV service throughout the United States. The satellites will have to use onboard thrusters and propellant to climb the rest of the way into circular 35,800 km (22,250 mi) orbits, where their orbital velocity will exactly match Earth’s rotation so they can hover over their region of choice. That high mass and Falcon 9’s booster recovery limited the rocket’s performance, so the satellites were inserted into an elliptical geostationary transfer orbit (GTO) with one end around 300 kilometers (~185 mi) up and the other about 20,000 kilometers (~12,400 mi) above Earth’s surface. The pair reportedly weighed around 7.3 tons (~16,000 lb), making it one of the heaviest geostationary payloads SpaceX has ever launched. (SpaceX)Ībout half an hour after that, Falcon 9’s orbital upper stage successfully deployed Intelsat’s Galaxy 33 and Galaxy 34 geostationary communications satellites. One of the better Falcon 9 ‘nebulae’ to date. Nine minutes after liftoff, the nebula’s snake-like tail was still easily visible after booster B1060 touched down on the drone ship’s deck, backed by the light show it had just created. Unlike all other orbital-class rockets, that bullseye is literal for Falcon 9’s booster. Intentionally or not, a camera normally used to capture live views of Falcon boosters landing on ASOG’s deck was pointed in the perfect direction to capture the nebula from a unique angle – essentially sitting in the bullseye of the rocket’s cosmic dart board. What made this one noteworthy was a new view streamed live from the deck of SpaceX’s drone ship A Shortfall of Gravitas (ASOG), which was stationed in the Atlantic Ocean about 650 kilometers (~400 mi) off the coast of Florida.
