These are some of the last good looks we'll get at NASA's huge James Webb Space Telescope before it leaves this world forever.

The observatory dwarfs the bunny suit-clad technicians getting Webb ready for launch, which is scheduled to take place Dec.

Webb, which NASA bills as the successor of its iconic (and still very functional) Hubble Space Telescope, arrived in French Guiana last Tuesday (Oct. 12) after a 16-day ocean voyage that covered 5,800 miles (9,300 kilometers). .

After launch, the telescope will motor to the Earth-sun Lagrange Point 2, a gravitationally stable spot in space about 930,000 miles (1.5 million km) from our planet.
