Read the two excerpts from Chapter Four of Windows to the Universe: Revolutions in Astronomy.One of the most significant challenges in JWST's design was ensuring the sunshield could unfold correctly after launch. It had to be folded precisely to fit into the spacecraft and then unfurl perfectly once in space—like a massive piece of origami. The success of this deployment was critical to the mission. When flight control confirmed it had unfolded correctly, the entire control room erupted in cheers!The JWST orbits at a location called Lagrange Point 2 (L2), more than one million miles from Earth. Lagrange points are areas where the gravitational forces of the Sun and Earth balance out, allowing an object like a telescope to stay in a stable orbit. Stationing JWST at L2 keeps the sunshield properly positioned to protect its instruments and ensures that the telescope always aligns with the Earth, making communication easier.What conclusion can best be drawn about JWST’s design and function?
