Humans have been traveling around the world for as long as our species has exist , and after a while it became authoritative to know where one is and where one can go . The oldest survivingmapsare over 2,500 years old , and since then humans ' power to create survey of their surroundings has massively improved thanks to technological advances . But it ’s only recently that everything has changed .
The technological invention that get those alteration are in picture taking , oculus , aviation , and aeronautics . Basically since the mid-1800s , man have been able to bring out visual record of the world around us , but it was not until the thirties that we had exposure of the curvature of the Earth – from a modest altitude of 6.4 kilometre ( 21,000 feet ) .
air travel prove that a bird’s - eye aspect could provide new insights . A few age later , high - altitude atmospherical balloons breached a world record , reach over 22 kilometre ( 72,395 feet ) and providing details about the atmosphere we had not get wind before . But it was with the first satellites , and thenastronauts , that our satellite came in full into centering .

NASA has put together awonderful collectionof historical photos of Earth from high in the air and from space , as well as Earth from other planet . It show what a special and yet slight place our little corner of the universe really is . Those missions , whether crewed or robotic , merit their kudos ( and the photos are splendid ) but there ’s a quite a little more to this that deserves our attention .
The first run atmospheric condition satellite was set up 64 days ago . On April 1 , 1960 , satelliteTIROS- Television Infrared Observation Satellite – begin take effigy of our planet . It uncover that Earth ’s sphere is not a shoes from which to entirely look at the bully beyond . Space way are associated with uranology and astronautics , but they also have fleets looking down on Earth .
In six - and - a - half decades , we have go from simple-minded imaging to a wide array of quad mission keeping an eye on all the changes in our planet .

Clouds , precipitations , winds , ice rink sheets , electromagnetic fields , and gravity – everything is up for grabs . Satellites fromNASA , theEuropean Space Agency , and many others work severally and together to better empathise what our major planet is like and how it is respond to theclimate crisis .
These eyes from the sky bring home the bacon fundamental data that informs many type of option : from your atmospheric condition - dependent outfit to international policy . Satellite information about our satellite plays a Brobdingnagian role and continues to meliorate , with moresophisticatedand specialized observers from the sphere .
