Question 1

True or false: Webb is named after a former NASA administrator who oversaw the Apollo program.

Accepted Answer

True. James E. Webb led NASA from 1961 to 1968, championing science and human spaceflight during the Apollo era.

Question 2

True or false: Webb's primary mirror is made of 18 hexagonal segments coated in gold.

Accepted Answer

True. The 6.5-meter mirror uses 18 beryllium segments with a thin gold coating to reflect infrared light more efficiently.

Question 3

True or false: Webb's sunshield is the size of a tennis court and keeps it at -233°C.

Accepted Answer

True. The five-layer sunshield, about 21 x 14 meters, blocks heat from the Sun, Earth, and Moon, cooling Webb to cryogenic temperatures.

Question 4

True or false: The James Webb Space Telescope orbits Earth at the same distance as the Hubble Space Telescope.

Accepted Answer

False. Webb actually orbits the Sun at the second Lagrange point (L2), about 1.5 million km from Earth—much farther than Hubble's low-Earth orbit.

Question 5

True or false: Webb can see the first stars and galaxies that formed after the Big Bang.

Accepted Answer

True. Its infrared sensitivity allows it to observe light from over 13.5 billion years ago, capturing the universe's earliest objects.

Question 6

True or false: Webb was launched in 2022 and will operate for exactly 5 years before running out of fuel.

Accepted Answer

False. Webb launched in December 2021 and has fuel for at least 10 years, possibly 20+, thanks to precise launch and station-keeping.

Question 7

True or false: Webb can observe planets in our solar system and detect their atmospheric composition.

Accepted Answer

True. Its infrared spectrographs analyze atmospheres of planets like Jupiter, Saturn, and even Mars, revealing gases and weather patterns.

Question 8

True or false: Webb was originally designed to be serviced by astronauts, like Hubble.

Accepted Answer

False. Unlike Hubble, Webb is too far away at L2 for any servicing mission, so it was built with extreme reliability and no repair access.
