James Web Space Telescope
The James Webb Space Telescope is a giant leap forward in telescope technology. It will allow us to see farther and deeper into space than ever before, and it will help us better understand the universe we live in.
While visible light is ideal for seeing our home planet, studying nearby celestial objects like comets and asteroids, and peering into star forming regions, other types of light are critical to understand stars and galaxies further away.
Infrared light allows us to peer through dust clouds that exist between us and distant celestial objects. This can reveal hidden details about distant galaxies and stars.
The James Webb Space Telescope will also be sensitive to mid-infrared radiation which allows us to look at young planets in formation around newly formed stars.
NASA’s James Webb Space Telescope is a partnership between NASA, ESA (the European Space Agency) and CSA (the Canadian Space Agency). It is scheduled to launch in 2018, though it may be slightly delayed as with many large projects.
James Web Telescope
The James Webb Space Telescope (JWST) is a space telescope that will be launched into low Earth orbit in 2021. It is named after James E. Webb, the second administrator of NASA. The JWST will be the largest and most powerful telescope ever built, and will be used to study the earliest stars and galaxies in the universe.
The JWST is a flagship mission of NASA’s Wide-Field Infrared Survey (WFIRST) program, and is one of three missions selected in August 2011 for further study.
In June 2014, NASA announced that it was incorporating an additional $530 million into its budget to accelerate work on JWST’s primary mirror.
The JWST is one of NASA’s Great Observatories, along with the Hubble Space Telescope, now in orbit around Earth, and Chandra X-ray Observatory, launched in 1999 aboard a rocket. The telescope has an expected cost of .9 billion USD.
It is scheduled for launch aboard an Ariane 5 rocket from French Guiana in October 2018 and should reach its L2 point at a distance of 1.5 million km (930,000 mi) from Earth approximately two months later.
The JWST is an international collaboration between NASA, ESA, and CSA. The primary mirror will have a diameter of 6.5 meters (21 ft) with a total mass of 7500 kg (16500 lb).
The telescope’s three instruments will work together to study all phases of astronomy; from infrared starlight to near-infrared solar systems to more energetic objects such as galaxies and quasars.
James Web
The James Webb Space Telescope (also known as JWST or Webb) is a space telescope that is planned to be launched in October 2018.
It will be the largest and most powerful telescope ever built, and will be able to see objects in greater detail than any other telescope currently in operation.
The telescope will be a successor to NASA’s Hubble Space Telescope, and will observe some of most distant objects in the universe, provide images of previously unobserved celestial structures, and collect long-wavelength radiation (redshifted light). It is expected to help astronomers unravel mysteries such as how galaxies are formed.
The JWST is named after James E. Webb, a former NASA administrator. In accordance with contemporary astronomy practice, it is also known as Webb or its full name.
The telescope will be launched by an Ariane 5 rocket from French Guiana in 2018 and placed in a halo orbit around L2, a gravitationally stable point beyond the Earth’s moon. Its design includes a sunshield with deployable units; making it capable of operating continuously for up to a decade.
The JWST originated in 1994 as the Next Generation Space Telescope (NGST), a NASA competition for space telescope concepts that was announced in 1993. In 1996, it was renamed as Next Generation Space Telescope (NGST).
James Web Telescope Launch Date
The James Webb Space Telescope is set to launch in October 2018. The spacecraft will be situated 1 million miles from Earth, where it will study the infrared light emanating from galaxies and stars. The data that the telescope collects will help scientists better understand the universe’s history and evolution.
According to NASA, Webb is more than twice as wide and twice as tall as Hubble, with a segmented primary mirror that’s almost seven times larger than its predecessor.
The mirror is hexagonal, built from 18 individual panels made of gold-coated beryllium. It can detect infrared light at 0.6–28 micrometers (μm) wavelengths.
On May 17, 2018, NASA Administrator Jim Bridenstine announced that the launch was being delayed until March-June 2019. During a routine check of a transducer in June 2018, corrosion was discovered on two wires inside an electronics box for Webb’s focal plane assembly (FPA).
A review found that loose cloth wipes used to clean components had trapped moisture and caused corrosion on wires in two adjacent boxes as well, raising concerns about similar damage in other units.
The issue was addressed by December 2018, and NASA accepted a recommendation to conduct additional reviews on all similar wiring harnesses throughout Webb’s systems. The revised launch date is March-June 2019.
Once launched, Webb will be placed at Sun-Earth Lagrange point 2 (L2), 1 million miles (1.6 million km) from Earth. It will replace Hubble as America’s primary space observatory for studying deep space objects and was assembled in its entirety by Ball Aerospace in Boulder, Colorado.

James Web Launch
The James Webb Space Telescope (JWST) is a space telescope that will be launched into low Earth orbit in 2021. It is the successor to the Hubble Space Telescope and is named after NASA’s second administrator, James E. Webb.
The JWST will have a large mirror, six times the diameter of Hubble’s, and will be able to observe light from the first stars and galaxies that formed in the early universe.
The JWST is a joint project of NASA, ESA, and CSA. The JWST’s design includes a sunshield that is as large as a tennis court. This will allow it to block out direct light from Earth and its atmosphere so that it can observe faint objects with greater clarity than ever before.
The JWST’s primary mirror will be 6.5 meters (21.3 feet) in diameter and is designed to see into infrared wavelengths.
When launched, it will be positioned 1.5 million kilometers (0.93 million miles) from Earth, in an orbit around Lagrangian point L2 which provides a view of both near and deep space, allowing it to observe at all times of day and night over most of the year.
After about ten years of operation, JWST will be de-orbited and burned up in Earth’s atmosphere. Its instruments are expected to last longer than that, with an estimated five-year operational lifetime.
In 2021, it is scheduled to launch on an Ariane 5 rocket into a geostationary orbit around Earth’s equator at a height of 35,800 kilometers (22,300 miles). At that point it will be able to see most of Earth’s surface at once.
James Web Orbit
The James Webb Space Telescope (JWST) is a space telescope that will be launched into low Earth orbit in 2021. It is the successor to the Hubble Space Telescope and is named after NASA’s second administrator, James E. Webb.
The JWST is a collaboration between NASA, ESA, and CSA. The prime contractor is Northrop Grumman (formerly ATK). The spacecraft will orbit approximately 1 million kilometers from Earth.
NASA has described JWST as the highest-priority large space science project in its history. It is estimated to cost $8.7 billion, plus another $2 billion for five years of operation.
The primary goals of JWST are to determine the structure and evolution of galaxies, black holes, and dark energy; study planetary systems, stars, and other objects throughout our universe.
The telescope will be able to see some of these objects as they were 13.5 billion years ago; older than previous spacecraft have seen. Scientists hope that JWST will allow them to perform a variety of investigations which have not been possible until now.
Web Space Telescope
The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope that will be the successor to the Hubble Space Telescope.
The JWST will have a primary mirror 6.5 meters (21.3 ft) in diameter, which is more than twice as wide as the Hubble’s 2.4-meter (7.9 ft) mirror.
The JWST is not strictly a space telescope in that all of its instruments and sensors will be located inside an enclosure called a Integrated Science Instrument Module (ISIM), which is designed to be detached from its mirror and placed into orbit around Earth’s Lagrangian point L2, where it will remain stable for long periods of time. However, once deployed in space, it will resemble Hubble.
The JWST will be too large to launch in a single space shuttle mission, so it will be launched in separate segments.
During its transit to L2, these components will have to use an autonomous navigation system as well as long-range communications to know where they are and adjust their path accordingly.
Detailed navigation and guidance algorithms along with advanced spacecraft communications equipment on board JWST will be developed by GSFC (Goddard Space Flight Center).
The JWST is designed to have a five-to-10-year lifetime, but it will be replaced by successive telescopes as technology improves.
When that happens, it could still be used as a communication satellite to relay data between Earth and these next generation space telescopes. The ISIM will also include a coronagraph and spectrograph.
Summary
The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope, to be launched in 2021. It will be the largest and most powerful telescope ever built, and will allow us to see farther back in time than ever before. JWST will help us to understand the formation and evolution of galaxies, as well as the birth of stars and planets.
