About 61% of those provide communications, including everything from satellite TV and Internet of Things (IoT) connectivity to global internet. More than half of Earth’s operational satellites are launched for commercial purposes. While sailors once relied on the stars, today we use satellites for GPS, navigation, and various other applications. Humans have long used space for navigation. Let’s take a closer look at who operates those satellites and how they apply their technology. With SpaceX’s planned Starlink constellation of 12,000 satellites and Amazon’s proposed constellation in the works, the new space race continues its acceleration. This means that by 2028, there could be 15,000 satellites in orbit. Over the coming decade, it’s estimated by Euroconsult that 990 satellites will be launched every year. NASA technology has contributed to many items used in everyday life, from smoke detectors to medical tests.As highlighted in the chart above, The Union of Concerned Scientists (UCS), determined that 2,666 operational satellites circled the globe in April of 2020. Among other benefits, these tests have helped engineers improve air transportation. These aircraft include planes that have set new records. NASA has helped develop and test a variety of cutting-edge aircraft. Satellites have revealed a wealth of data about Earth, resulting in valuable information such as a better understanding of weather patterns. Telescopes have allowed scientists to look at the far reaches of space. NASA’s robotic space probes have visited every planet in the solar system and several other celestial bodies. Currently, NASA has astronauts living and working on the International Space Station. The Mercury, Gemini and Apollo programs helped NASA learn about flying in space and resulted in the first human landing on the moon in 1969. When NASA started, it began a program of human spaceflight. Each center is responsible for working on various parts of NASA’s missions. NASA’s Kennedy Space Center in Florida launches spacecraft around the Earth and beyond. But people there hold many other jobs, too, from secretaries to writers to lawyers to teachers. Many NASA workers are scientists and engineers. Astronauts may be the best-known NASA employees, but they only represent a small number of the total workforce. The combined workforce represents a wide variety of jobs. Those people are hired by companies that NASA pays to do work for it. Many more people work with the agency as government contractors. The agency has nine centers, the Jet Propulsion Laboratory, and seven test and research facilities located in several states around the country. NASA’s Headquarters is in Washington, D.C. The agency also involves students in NASA missions to help them get excited about learning. NASA offers training to help teachers learn new ways to teach science, technology, engineering and mathematics. NASA has a tradition of investing in programs and activities that inspire and engage students, educators, families and communities in the excitement and discovery of exploration. They will be the adventurers who will continue the exploration of the solar system and universe in the years to come. NASA’s Education Office helps teachers to prepare the students who will be the engineers, scientists, astronauts and other NASA workers of the future. For example, companies can use NASA discoveries to create new “spin-off” products. The agency shares what it learns, so that its information can make life better for people all over the world. In addition to those major missions, NASA does many other things. NASA is also beginning a new program to send humans to explore beyond the moon to Mars. New developments improve air travel and other aspects of flight. Space probes study the solar system, and beyond. Satellites help scientists learn more about Earth. Astronauts in orbit conduct scientific research. But most probably have no idea about how many different things the agency does. Many people know something about NASA’s work. The NASA logo is painted on the outside of the Vehicle Assembly Building at Kennedy Space Center in Florida, where spacecraft are prepared for launch.
