Surprise 1: A Long and Complex History

The JWST's development comes with a hefty price tag of $10 billion, but what’s even more surprising is the extensive timeline leading to its creation. If you were to guess the start date of this project, would you choose 1996? That's correct! Those who began working on the JWST when they were about 25 years old are now nearing retirement. In fact, some professionals involved in the project weren’t even born when it first began. Initially named the Next Generation Space Telescope (NGST), it was renamed in 2002 to honor James Webb, who served as NASA's administrator from 1961 to 1968.

Surprise 2: An Unconventional Orbit

Unlike its predecessor, the Hubble Space Telescope, which orbits Earth, the JWST operates at the L2 Lagrange point, which orbits the Sun. This unique positioning allows the telescope to maintain a stable position relative to Earth and the Sun, reducing interference from our planet's light pollution. Imagine trying to stargaze from a city filled with lights; moving to a remote area allows for a clearer view. Similarly, the JWST’s distance from Earth helps it capture more precise astronomical data.

Surprise 3: A Costly Yet Low-Budget Option

Though $10 billion sounds exorbitant, this was considered the economical choice compared to earlier estimates. Originally, the JWST was projected to cost $500 million with a launch date set for 2007. However, as development progressed, costs skyrocketed due to the complex nature of the project and delays from extensive testing. The JWST required precise execution, as there wouldn’t be a second chance to fix issues once in space.

Surprise 4: An International Collaboration

The JWST wasn’t launched by NASA alone; it was a collaborative effort with the European Space Agency (ESA) and the Canadian Space Agency (CSA). The launch took place in French Guiana using an Ariane 5 rocket, which is renowned for its reliability. This international partnership highlights the collaborative spirit of modern space exploration.

Surprise 5: Lifespan Expectations

Initially, the JWST was designed for a maximum lifespan of 10 years, but recent updates suggest it may operate well beyond that. Thanks to the precision of the Ariane 5 launch, the telescope has enough propellant to extend its operational life significantly. This means that for an investment of $10 billion, we might enjoy many more years of invaluable astronomical data.
