Animation: The James Webb Space Telescope's Orbit
James Webb Space Telescope orbit as seen from above the Sun's north pole and as seen from Earth's perspective.
The James Webb Space Telescope will not be in orbit around the Earth, like the Hubble Space Telescope is - it will actually orbit the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2. What is special about this orbit is that it lets the telescope stay in line with the Earth as it moves around the Sun. This allows the satellite's large sunshield to protect the telescope from the light and heat of the Sun and Earth (and Moon).
This animation has no sound and is not to scale.

James Webb Space Telescope Orbit - Animation #shorts
This animation illustrates the James Webb Space Telescope's orbit as seen from above the Sun's north pole.
Webb does not orbit around the Earth. Instead, it orbits the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange Point, or L2. This orbit lets Webb stay in line with the Earth as it moves around the Sun, allowing its sunshield to always provide the telescope protection from the light and heat of the Sun and Earth (and Moon).

Tower Extension Test a Success for NASA’s James Webb Space Telescope
To test the James Webb Space Telescope’s readiness for its journey in space, technicians successfully commanded it to deploy and extend a critical part of the observatory known as the Deployable Tower Assembly.
The primary purpose of the deployable tower is to create a large gap between the upper part of the observatory that houses its iconic gold mirrors and scientific instruments, and the lower section known as the spacecraft bus which holds its comparatively warm electronics and propulsion systems. By creating a space between the two, it allows for Webb’s active and passive cooling systems to bring its mirrors and sensors down to staggeringly cold temperatures required to perform optimal science.

The Greatest Discoveries of the James Webb Telescope Will Stun You!
The Greatest Discoveries of the James Webb Telescope Will Stun You!
Over the past two years, scientists have used the James Webb Space Telescope (JWST) to explore the Cosmic Dawn, the period shortly after the Big Bang when the first galaxies were formed.
The telescope is equipped with infrared-sensing instruments capable of detecting light that was emitted by the most ancient stars and galaxies. Essentially, the telescope allows scientists to see back in time roughly 13.5 billion years, near the beginning of the universe as we know it.

How did NASA engineers build and launch the most ambitious telescope of all time? Follow the dramatic story of the James Webb Space Telescope—the most complex machine ever launched into space. If it works, scientists believe that this new eye on the universe will peer deeper back in time and space than ever before to the birth of galaxies, and may even be able to “sniff” the atmospheres of exoplanets as we search for signs of life beyond Earth. But getting it to work is no easy task. The telescope is far bigger than its predecessor, the famous Hubble Space Telescope, and it needs to make its observations a million miles away from Earth—so there w...

This animation illustrates the James Webb Space Telescope's orbit as seen from above the Sun's north pole.
Webb does not orbit around the Earth. Instead, it orbits the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange Point, or L2. This orbit lets Webb stay in line with the Earth as it moves around the Sun, allowing its sunshield to always provide the telescope protection from the light and heat of the Sun and Earth (and Moon).

To test the James Webb Space Telescope’s readiness for its journey in space, technicians successfully commanded it to deploy and extend a critical part of the observatory known as the Deployable Tower Assembly.
The primary purpose of the deployable tower is to create a large gap between the upper part of the observatory that houses its iconic gold mirrors and scientific instruments, and the lower section known as the spacecraft bus which holds its comparatively warm electronics and propulsion systems. By creating a space between the two, it allows for Webb’s active and passive cooling systems to bring its mirrors and sensors down to staggeringly cold temperatures required to perform optimal science.
Webb was designed to look for faint traces of infrared light, which is essentially heat energy. To detect the extremely faint heat signals of astronomical objects that are incredibly far away, the telescope itself has to be very cold and stable.
During the test, the tower was slowly extended 48 inches (1.2 meters) upward over the course of several hours, in the same maneuver it will perform once in space. Simulating the zero-gravity environment Webb will operate in, engineers employed an innovative series of pulleys, counterbalances and a special crane called a gravity-negation system that perfectly offloaded all of the effects of Earth’s gravity on the observatory. Now that Webb is fully assembled, the difficulty of testing and properly simulating a zero-gravity environment has increased significantly.
“The Deployable Tower Assembly worked beautifully during the test,” said Alphonso Stewart the Webb deployment systems lead for NASA's Goddard Space Flight Center in Greenbelt, Maryland. “It performed exactly as predicted, and from our expectations from previous tests before the full observatory was assembled. This was the first time that this part of Webb was tested in its flight-like configuration to the highest level of fidelity we possibly could. This test provides the opportunity to assess all interfaces and interactions between the instrument and bus sections of the observatory."
In addition to helping the observatory cool down, the Deployable Tower Assembly is also a big part of how Webb is able to pack down into a smaller size to fit inside an Ariane 5 rocket for launch. Webb is the largest space science observatory ever built, but to fit a telescope that big into a rocket, engineers had to design it to fold down into a much smaller configuration. Webb’s Deployable Tower Assembly helps Webb to just barely fit inside a 17.8-foot (5.4-meter) payload fairing. Once in space, the tower will extend to give the rest of Webb’s deployable parts, such as the sunshield and mirrors, the necessary amount of room needed to unpack and unfold into a fully functional infrared space observatory.

During the test, the tower was slowly extended 48 inches (1.2 meters) upward over the course of several hours, in the same maneuver it will perform once in space. Simulating the zero-gravity environment Webb will operate in, engineers employed an innovative series of pulleys, counterbalances and a special crane called a gravity-negation system that perfectly offloaded all of the effects of Earth’s gravity on the observatory. Now that Webb is fully assembled, the difficulty of testing and properly simulating a zero-gravity environment has increased significantly.
“The Deployable Tower Assembly worked beautifully during the test,” said Alphonso Stewart the Webb deployment systems lead for NASA's Goddard Space Flight Center in Greenbelt, Maryland. “It performed exactly as predicted, and from our expectations from previous tests before the full observatory was assembled. This was the first time that this part of Webb was tested in its flight-like configuration to the highest level of fidelity we possibly could. This test provides the opportunity to assess all interfaces and interactions between the instrument and bus sections of the observatory."
In addition to helping the observatory cool down, the Deployable Tower Assembly is also a big part of how Webb is able to pack down into a smaller size to fit inside an Ariane 5 rocket for launch. Webb is the largest space science observatory ever built, but to fit a telescope that big into a rocket, engineers had to design it to fold down into a much smaller configuration. Webb’s Deployable Tower Assembly helps Webb to just barely fit inside a 17.8-foot (5.4-meter) payload fairing. Once in space, the tower will extend to give the rest of Webb’s deployable parts, such as the sunshield and mirrors, the necessary amount of room needed to unpack and unfold into a fully functional infrared space observatory.

The Greatest Discoveries of the James Webb Telescope Will Stun You!
Over the past two years, scientists have used the James Webb Space Telescope (JWST) to explore the Cosmic Dawn, the period shortly after the Big Bang when the first galaxies were formed.
The telescope is equipped with infrared-sensing instruments capable of detecting light that was emitted by the most ancient stars and galaxies. Essentially, the telescope allows scientists to see back in time roughly 13.5 billion years, near the beginning of the universe as we know it.

Discover how NASA engineers built and launched the most ambitious telescope of all time.
Official Website: https://www.pbs.org/nova/ | #NOVAPBS
How did NASA engineers build and launch the most ambitious telescope of all time? Follow the dramatic story of the James Webb Space Telescope—the most complex machine ever launched into space. If it works, scientists believe that this new eye on the universe will peer deeper back in time and space than ever before to the birth of galaxies, and may even be able to “sniff” the atmospheres of exoplanets as we search for signs of life beyond Earth. But getting it to work is no easy task. The telescope is far bigger than its predecessor, the famous Hubble Space Telescope, and it needs to make its observations a million miles away from Earth—so there will be no chance to go out and fix it. That means there’s no room for error; the most ambitious telescope ever built needs to work perfectly. Meet the engineers making it happen and join them on their high stakes journey to uncover new secrets of the universe.
