NASA determined that the observatory should have enough propellant to operate in space for at least 10 years after analyzing where it is now and how it got there.
Mission engineers and scientists were hoping for closer to 10 years for the lifetime of the mission.
The precision of the Ariane 5 launch on December 25 is one of the factors that led to the "significantly more than 10 years" announcement.
The first two mid-course correction maneuvers took less fuel than expected because of the precise trajectory of the JWST.
A 65-minute burn took place about 12 hours after the launch. A burn lasting as long as 3 hours could have been required.
The observatory's speed was increased by 45 mph due to the first burn. The second correction maneuver added around 6.3 mph to the speed.
The amount of fuel used for getting to L2 and maintaining its orbit is limited by the possibility that the components will degrade over time in the harsh environment of space.
The precise trajectory of the observatory means more propellant for maintenance and management down the road, which means a longer operational lifetime.
Which also means more research.

The largest and most important mid-course correction (MCC), designated MCC-1a, has already been successfully executed as planned, according to Randy Kimble, a project scientist at NASA.
The earlier the course correction is made, the less propellant it requires.
Why is the JWST going there?

The first parts of the sun shield have successfully deployed, which is a big news from the company.
On December 28, the sun shield pallets were unfolded. The Deployable Tower Assembly has been extended for six hours. The sun shield room is created by the space between the telescope and the spaceship. This space will help to keep the telescope warm.
The sun shield covers, the extension of the mid-booms, and the tensioning of the five Kapton layers of the sun shield are the next steps.

Over the next few days, this will take place. NASA says that because the deployment of the sun shield is one of the most challenging missions they have ever attempted, the mission operations team built flexibility into the planned timelines so that the schedule and even sequence of the next steps could change in the coming days.
New details are being added to the "Where is Webb" website, which is where you can find all sorts of information. The temperatures of the craft can be tracked.
It will be warm on one side and cold on the other side of the house. The sun shield will always be facing the Sun to block out the heat and light that come from it.
You're hot and you're cold. The sun shield will always be facing the Sun to block out heat and light, as the mirrors need to stay extremely cold to observe faint heat signals in the universe.

On the hot side, parts of the town will reach temperatures as high as 185 degrees Fahrenheit. The temperature on the cold side is -233 degrees Celsius.
NASA said that temperatures will change as the program unfolds and then cool down over the next few months.
