![]() The volume of carbon dioxide pumped into the atmosphere by human activities is the dominant force driving ongoing and future climate change. It also seeks to track how these processes might change in a warming world with increasing levels of carbon dioxide and methane emissions from human activities. NASA’s Earth science program works to improve our understanding of how carbon absorption and emission processes work in nature. The James Webb Space Telescope was named after the NASA Administrator who crafted the Apollo program, and who was a staunch supporter of space science.Īs carbon dioxide levels in Earth's atmosphere have increased in recent decades, the planet's land and ocean have continued to absorb about half of manmade emissions. Webb will operate in an orbit about 1.5 million km (1 million miles) from the Earth. Both the mirror and sunshade won't fit onto the Ariane 5 rocket fully open, so both will fold up and open once Webb is in outer space. Webb will have a large primary mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. Webb's instruments are designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range. Webb will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. Webb will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. The project is working to a 2021 launch date. The James Webb Space Telescope (sometimes called JWST) is a large, infrared-optimized space telescope. The James Webb Space Telescope was named after the NASA Administrator who crafted the Apollo program, and who was a staunch supporter of space science. Webb is currently in its operational orbit about 1.5 million km (1 million miles) from the Earth at a location known as Lagrange Point 2 (L2). Both the mirror and sunshade are too large to fit onto the Ariane 5 rocket fully open, so both were folded which meant they needed to be unfolded in space. Webb has a large primary mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. ![]() ![]() After launch, the observatory was successfully unfolded and is being readied for science. The observatory launched into space on an Ariane 5 rocket from the Guiana Space Centre in Kourou, French Guiana on December 25, 2021. ![]()
