NASA and its partners working on the James Webb Space Telescope have completed their final tests of the giant observatory and are now preparing it for a trip to a South American spaceport for a launch later this year.
Conceived more than 30 years ago as a successor of the then new Hubble Space Telescope, James Webb will be the largest observatory ever to be put in orbit. It is designed to use its infrared eyes to peer further into the universe's history than ever before. With its 6.5-meter in diameter gold-plated mirror, the telescope will attempt to answer questions about the formation of first stars and galaxies out of the darkness of the early universe.
At 44 feet (13.2 meters) long and 14 feet (4.2 m) wide, the telescope is about the size of a large tractor-trailer truck, fitted with intricate sun shades that could cover a tennis court once unfolded.
The program faced many delays, not just due to the COVID-19 pandemic, but seems finally on track to start producing ground-breaking astronomical observations. The testing, which took place at the facilities of prime contractor Northrop Grumman in California, made sure that nothing would go wrong with the more than $10 billion spacecraft during launch and once in space.
