"We now have verified that NASA and its partners have an outstanding telescope and set of science instruments," said Bill Ochs, the Webb telescope project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The Webb telescope was able to detect the light, and all of the optical systems were able to process it.
Then, the telescope was able to track the "star" and its movement, giving scientists confidence that the Webb instrument will work once in space.
"That is what makes us most nervous," admitted Jonathan Homan, project manager for Webb telescope test team in Houston.

The James Webb Space Telescope is one (cold) step closer to launching into space. The telescope will only be flown to French Guiana – for a launch aboard an Ariane 5 rocket – no earlier than the spring of 2019. #Aerospace #Trend
