About Webb:-
-The James Webb Space Telescope is the largest, most powerful space
telescope ever built. It will allow scientists to look at what our universe was
like about 200 million years after the Big Bang. The telescope will be able to
capture images of some of the first galaxies ever formed. It will also be able to
observe objects in our solar system from Mars outward, look inside dust
clouds to see where new stars and planets are forming and examine the
atmospheres of planets orbiting other stars.
-The Webb telescope is as tall as a 3-story building and as long as a tennis
court! It is so big that it has to fold origami-style to fit inside the rocket to
launch. The telescope will unfold, sunshield first, once in space.
-The James Webb Space Telescope sees the universe in light that is invisible to
human eyes. This light is called infrared radiation, and we can feel it as heat.
Firefighters use infrared cameras to see and rescue people through the smoke
in a fire. The James Webb Space Telescope will use its infrared cameras to see
through dust in our universe. Stars and planets form inside those dust clouds,
so peeking inside could lead to exciting new discoveries! It will also be able to
see objects (like the first galaxies) that are so far away that the expansion of
the universe has made their light shift from visible to infrared!
-It will be used to see the galaxy in a new and better way and will help in
research
Some more facts:-
-The Webb telescope’s cameras are sensitive to heat from the Sun. Just like
you might wear a hat or a visor to block the Sun from your eyes, Webb has a
sunshield to protect its instruments and mirrors. The telescope’s sunshield is
about the size of a tennis court. The temperature difference between the
sun-facing and shaded sides of the telescope is more than 600 degrees
Fahrenheit!
-Space telescopes “see” by using mirrors to collect and focus light from
distant stars. The bigger the mirror, the more details the telescope can see.
It’s very difficult to launch a giant, heavy mirror into space. So, engineers
gave the Webb telescope 18 smaller mirrors that fit together like a puzzle.
The mirrors fold up inside the rocket, then unfold to form one large mirror in
orbit.
Why are the mirrors gold? A thin layer of gold helps the mirrors reflect
infrared light!
Launch of the Webb
Launch Vehicle
The James Webb Space Telescope was launched on an Ariane 5 rocket. The
launch vehicle and launch site are part of the European Space Agency's
contribution to the mission. The Ariane 5 is one of the world's most reliable
launch vehicles and was chosen for a combination of reliability (it was the only
launch vehicle that met NASA's requirements for launching a mission like
Webb) and for the value it brings via our international partnership.
Launch Location
Webb was launched from Arianespace's ELA-3 launch complex at Europe's
Spaceport located near Kourou, French Guiana. It is beneficial for launch sites
to be located near the equator - the spin of the Earth can help give an
additional push. The surface of the Earth at the equator is moving at 1670
km/hr.

It is beneficial for launch sites to be located near the equator - the spin of the Earth can help give an additional push. The surface of the Earth at the equator is moving at 1670 km/hr.
  • 7. Additional Details:- Additional Details The Launch Segment has 3 primary components: 1. Launch Vehicle: an Ariane 5 with the cryogenic upper stage. Provided in the single launch configuration, with a long payload fairing providing a maximum 4.57 meter static diameter and useable length of 16.19 meters. 2. Payload Adapter, comprising the Cone 3936 plus ACU 2624 lower cylinder and clamp-band, which provides the separating mechanical and electrical interface between the Webb Observatory and the Launch Vehicle. 3. Launch campaign preparation and launch campaign. The launch campaign preparation and launch campaign is the mutual responsibility of NASA, ESA, Northrop Grumman and ArianeSpace. Webb Launch Configuration For the telescope to fit into the rocket, it must fold up. These images show how it fits into the rocket fairing.
  • 8. Commissioning of JWST:- Commissioning JWST is a complex, 6 month process: • JWST unfolds. A tower extends. The tennis-court-sized sunshield deploys. The secondary mirror supports unfold. 6 of the 18 primary mirror segments swing out on hinges. • JWST cools passively. We must wait for the science instruments to get cold enough. • JWST is thermally demanding. The 40-50 K telescope and science instruments are isolated from the 300K spacecraft. • JWST is segmented. The 18 primary mirror segments must be phased, from initial alignments of millimeters, to a final alignment of tens of nanometers. • JWST has 4 science instruments with 17 observing templates (modes)
  • 9. Where in Space:- JWST operates in a halo orbit, circling around a point in space known as the Sun-Earth L2 Lagrange point, approximately 1,500,000km (930,000 mi) beyond Earth's orbit around the Sun. Its actual position varies between about 250,000 km (160,000 mi) and 832,000 km (517,000mi) from L2 as it orbits, keeping it out of both Earth and Moon's shadow. By way of comparison, Hubble orbits 550 km (340 mi) above Earth's surface, and the Moon is roughly 400,000 km (250,000 mi) from Earth. Objects near this Sun-Earth L2 point can orbit the Sun in synchrony with the Earth, allowing the telescope to remain at a roughly constant distance with continuous orientation of its unique sunshield and equipment bus toward the Sun, Earth and Moon. Combined with its wide shadow-avoiding orbit, the telescope can simultaneously block incoming heat and light from all three of these bodies and avoid even the smallest changes of temperature from Earth and Moon shadows that would affect the structure, yet still maintain uninterrupted solar power and Earth communications on its sun-facing side. This arrangement keeps the temperature of the spacecraft constant and below the 50 K (−223 °C; −370 °F) necessary for faint infrared observations.
  • 10. Recent Discoveries:- NASA’s James Webb Space Telescope is aligned across all four of its science instruments,as seen in a previous engineeringimage showing the observatory’s full field of view. Now, we take a closer look at that same image, focusing on Webb’s coldest instrument: the Mid-Infrared Instrument, or MIRI. The MIRI test image (at 7.7 microns) shows part of the Large Magellanic Cloud. This small satellite galaxy of the Milky Way provideda dense star field to test Webb’s performance. Here, a close-up of the MIRI image is compared to a past image of the same target taken with NASA’s Spitzer Space Telescope’s Infrared Array Camera (at 8.0 microns). The retired Spitzer telescope was one of NASA’s Great Observatoriesand the first to provide high-resolutionimages of the near- and mid-infrared universe.Webb, with its significantlylarger primary mirror and improved detectors, will allow us to see the infrared sky with improved clarity, enablingeven more discoveries.
