American Space Agency NASA has targeted to launch its James Webb Space Telescope by May 2020. After an internal assessment in relation to the remaining work of the Complex Space Observatory, on Tuesday, NASA announced its goal of launching the next generation of space telescopes in one year.

“Webb is the highest priority project for the agency’s science mission directorate,” said Robert Lightfoot, the Acting Administrator of the National Aeronautics and Space Administration (NASA). “The issues brought to light with the spacecraft element are prompting us to take the necessary steps to refocus our efforts on the completion of this ambitious and complex observatory.”

David Spergel, an astrophysicist at Princeton University, told Scientific American, “We are all disappointed; so many of us are eagerly awaiting Webb’s science. However, it is better to have a modest delay and a modest overrun and have a successful mission.”
