    Mirror Segment Deployment Tracker
    Nominal Event Time: Launch + 18-28 days

    Status: Ongoing

    The adjacent image tracks the progress of the individual primary mirror segments (A,B,C) and the secondary (SM) mirror as they move upward 12.5mm from their stowed launch position to a deployed state where they are ready for the mirror alignment process. View a full screen copy.

    The mirrors move in very small increments over the course of ~10 days to complete their deployment. They move approximately 1mm per day each. For more detail on this process read this blog entry.

    Each primary mirror segment has an ID which consists of a letter (A,B,C) followed by a number. The letter denotes one of 3 different 'prescriptions' for each group of primary mirror segments.

    NOTE: Segment A3 and A6 will be moved separately at the end of the process because their position sensors are read out in a different way.
    The station is crewed by NASA astronauts as well as Russian Cosmonauts and a mixture of Japanese, Canadian and European astronauts as well.

    Actuator testing and individual mirror segment deployments
    Nominal Event Time: UPDATE: Launch + 18 days (Jan 12)
    Status: Ongoing

    The primary mirror wings are now fully deployed and latched into place, but the individual mirror segments remain in their launch configuration. This operation is a multi-day, multi-step activity to activate and move each of the 18 primary mirror segments and the secondary mirror from their stowed launch configuration to a deployed position ready for alignment.

    The 18 primary mirror segments and secondary mirror are adjustable via six actuators that are attached to the back of each mirror. The primary mirror segments also have an additional actuator at its center that adjusts its curvature. The telescope's tertiary mirror remains stationary. The primary and secondary mirror segments will move a total of 12.5mm, in small increments, over the course of ~10 days to complete each segment's deployment.

    After all individual mirror segment deployments are completed, the detailed optical mirror alignment process begins which is about a 3 month process. In parallel, as temperatures cool enough, instrument teams will turn on their instruments and begin each instrument's commissioning process.

    What is the James Webb Space Telescope?
    The James Webb Space Telescope, also called Webb or JWST, is a large, space-based observatory, optimized for infrared wavelengths, which will complement and extend the discoveries of the Hubble Space Telescope. It will have longer wavelength coverage and greatly improved sensitivity. The longer wavelengths enable Webb to look further back in time to find the first galaxies that formed in the early Universe, and to peer inside dust clouds where stars and planetary systems are forming today.
    What was the Webb called before it was named after James Webb?
    The James Webb Space Telescope was originally called the Next Generation Space Telescope, or NGST. It was called Next Generation because Webb will build on and continue the science exploration started by the Hubble Space Telescope. Discoveries by Hubble and other telescopes have caused a revolution in astronomy and have raised new questions that require a new, different, and more powerful telescope. Webb is also a Next Generation telescope in an engineering sense, introducing new technologies like the lightweight, deployable primary mirror that will pave the way for future missions. On 10 September 2002, the Next Generation Space Telescope was named in honor of James E. Webb, NASA's second administrator.

    Who was James E. Webb?
    This space-based observatory is named after James E. Webb (1906- 1992), NASA's second administrator. Webb is best known for leading Apollo, a series of lunar exploration programs that landed the first humans on the Moon. However, he also initiated a vigorous space science program that was responsible for more than 75 launches during his tenure, including America's first interplanetary explorers. For more information, please visit this page on our website. James E. Webb's official NASA biography can be found here.
    How will Webb be better than the Hubble Space Telescope?
    Webb is designed to look deeper into space to see the earliest stars and galaxies that formed in the Universe and to look deep into nearby dust clouds to study the formation of stars and planets. In order to do this, Webb will have a much larger primary mirror than Hubble (2.7 times larger in diameter, or about 6 times larger in area), giving it more light-gathering power. It also will have infrared instruments with longer wavelength coverage and greatly improved sensitivity than Hubble. Finally, Webb will operate much farther from Earth, maintaining its extremely cold operating temperature, stable pointing and higher observing efficiency than with the Earth-orbiting Hubble. Here is a feature that contrasts Webb with Hubble.

    Why is Webb not serviceable like Hubble?
    Hubble is in low-Earth orbit, located approximately 375 miles (600 km) away from the Earth, and is therefore readily accessible for servicing. Webb will be operated at the second Sun-Earth Lagrange point, located approximately 1 million miles (1.5 million km) away from the Earth, and will therefore be beyond the reach of any crewed vehicle currently being planned for the next decade. In the early days of the Webb project, studies were conducted to evaluate the benefits, practicality and cost of servicing Webb either by human space flight, by robotic missions, or by some combination such as retrieval to low-Earth orbit. Those studies concluded that the potential benefits of servicing do not offset the increases in mission complexity, mass and cost that would be required to make Webb serviceable, or to conduct the servicing mission itself.

    Why does the sunshield have five layers rather than one thick one?
    Each successive layer of the sunshield is cooler than the one below. The heat radiates out from between the layers, and the vacuum between the layers is a very good insulator. One big thick sunshield would conduct the heat from the bottom to the top more than 5 layers separated by vacuum.

    How will Webb communicate with scientists at Earth?
    The Webb will send science and engineering data to Earth using a high frequency radio transmitter. Large radio antennas that are part of the NASA Deep Space Network will receive the signals and forward them to the Webb Science and Operation Center at the Space Telescope Science Institute in Baltimore, Maryland, USA.

    WEBB IS FULLY DEPLOYED!
    The largest, most complex telescope ever launched into space is fully deployed.
    Nominal Event Time: Launch + 14 days (Saturday 1/8/22)
    Status: Completed. WATCH: Post-Deployment Briefing | Re-Watch Live Broadcast
    Webb will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.
    Webb will continue to travel to the second Lagrange point (L2) for another two weeks, at which point it will enter a large orbit around the L2 point. The following five months will be used to cool the telescope to operating temperature, fine-tune the mirror alignment, and calibrate the instruments.
    James Edwin Webb (October 7, 1906 – March 27, 1992) was an American government official who served as Undersecretary of State from 1949–1952. He was also the second appointed administrator of NASA from February 14, 1961, to October 7, 1968. Webb oversaw NASA from the beginning of the Kennedy administration through the end of the Johnson administration, thus overseeing each of the critical first crewed missions throughout the Mercury and Gemini programs until days before the launch of the first Apollo mission. He also dealt with the Apollo 1 fire.

    In 2002, the Next Generation Space Telescope (NGST) was renamed the James Webb Space Telescope as a tribute to Webb.

    Day 19 of the James Webb Space Telescope
    The James Webb Space Telescope (JWST) is a space telescope developed by NASA with contributions from the European Space Agency (ESA), and the Canadian Space Agency (CSA). The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program. It is intended to succeed the Hubble Space Telescope as NASA's flagship mission in astrophysics. JWST was launched on 25 December 2021 on Ariane flight VA256. It is designed to provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observations of some of the most distant events and objects in the Universe such as the formation of the first galaxies, and allowing detailed atmospheric characterization of potentially habitable exoplanets.

    The primary mirror of JWST, the Optical Telescope Element, consists of 18 hexagonal mirror segments made of gold-plated beryllium, which combine to create a 6.5 m (21 ft)-diameter mirror – considerably larger than Hubble's 2.4 m (7 ft 10 in) mirror. Unlike the Hubble telescope, which observes in the near ultraviolet, visible, and near infrared (0.1–1.0 μm) spectra, JWST will do so in a lower frequency range, from long-wavelength visible light (red) through mid-infrared (0.6–28.3 μm). This will enable it to observe high-redshift objects that are too old and too distant for Hubble.[12][13] The telescope must be kept very cold to observe in the infrared without interference, so it will be deployed in space near the Sun–Earth L2 Lagrange point, about 1.5 million kilometres (930,000 mi) from Earth (0.01 au – 3.9 times the average distance to the Moon).[14] A large sunshield made of silicon- and aluminum-coated Kapton will keep its mirror and instruments below 50 K (−223 °C; −370 °F).

    The NASA Goddard Space Flight Center (GSFC) in Maryland managed the development and the Space Telescope Science Institute is operating Webb. The prime contractor was Northrop Grumman.

    Development began in 1996 for a launch that was initially planned for 2007 with a US$500 million budget. There were numerous delays and cost overruns, including a major redesign in 2005, a ripped sunshield during a practice deployment, a recommendation from an independent review board, the COVID-19 pandemic, issues with the Ariane 5 rocket and the telescope itself, and communications issues between the telescope and the launch vehicle. Concerns among the involved scientists and engineers about the launch and deployment of the telescope have been well-described.

    Construction was completed in late 2016, at which point an extensive testing phase began. JWST was launched at 12:20 UTC on 25 December 2021 by an Ariane 5 launch vehicle from Kourou, French Guiana, on the northeastern coast of South America, and was released from the upper stage 27 minutes later. The telescope was confirmed to be receiving power, and as of December 2021 is traveling to its target destination.

    The most recently completed deployment step for Webb is displayed along a timeline that also indicates the major deployment phases. Note that the timing, duration and/or order of deployment phases and steps may change. This page shows the default/nominal timing and order. The phases mark the start and end of major groups of deployment steps. The most recently completed deployment step is shown as a spacecraft icon on the timeline and is detailed below with a larger image and links. Deployment phases are shown on the timeline in a light blue overlay on screens large enough to display this info, otherwise hidden.


    The speed and distance numbers displayed track Webb's distance travelled from Earth to entry into its L2 orbit. The numbers are derived from precalculated flight dynamics data that models Webb's flight up to its entry into L2 orbit. The distance shown is the approximate distance travelled as opposed to altitude.
    Distance to L2
    L2 is approximately 1 million miles from Earth (932056 miles/1.5M km to be exact). But Webb never actually arrives at L2, it is travelling to enter an orbit around L2. Webb's L2 orbit is very large in size and it enters its orbit before it reaches the linear distance between Earth and L2. Webb's orbit around L2 is known as a halo orbit which, rather than a single path, is an orbit that periodically varies through a series of paths around L2.
    Arrival at L2 Orbit

    To get the exact orbit needed, Webb's trajectory is fine tuned by a number of burns along the way. You can learn more about these Mid Course Correction (MCC) burns on the Deployment Explorer page. The final burn, MCC2, inserts Webb into the desired L2 halo orbit. The MCC2 burn is nominally planned for Launch + 29days. At the end of that burn we can say Webb is In L2 Orbit and so has arrived at L2.

    Therefore, this page, for purposes of calculations uses a distance to L2 orbit entry number ( and timing ) that is a sufficient distance and time after the MCC2 burn to say Webb is in L2 Orbit. Once in L2 orbit, this page will no longer track distance, but will track temperatures. The spacecraft will continue to cool to operating temperatures and numerous tests and calibrations occur to ready it for operations and its first images over the months that follow.



    Temperature control is a vital aspect of Webb's design, engineering and operations. Of the many temperature monitoring points on the observatory, this page displays 2 hot side and 2 cold side temperatures that are a good indication of overall temperature status and trends.


    There are many more temperature sensors on the observatory that our engineers monitor throughout the deployment, commissioning and operations processes. The data points shown here give a good overall indication of the temperature trends on each side of the sunshield as we move through deployment and commissioning. They illustrate the great contrast between the hot and cold sides of the spacecraft and the incredible engineering and effectiveness of the sunshield. These temperature observations are reported daily from actual spacecraft telemetry data. Temperature values will continue to be reported in the months that follow the completed deployment as the spacecraft cools to operational values. NASA

    How will Webb communicate with scientists at Earth?

    The Webb will send science and engineering data to Earth using a high frequency radio transmitter. Large radio antennas that are part of the NASA Deep Space Network will receive the signals and forward them to the Webb Science and Operation Center at the Space Telescope Science Institute in Baltimore, Maryland, USA.

    James Webb Space Telescope: Primary Mirror Deployment – Mission Control Live

    WEBB IS FULLY DEPLOYED!
    The largest, most complex telescope ever launched into space is fully deployed.

    Nominal Event Time: Launch + 14 days (Saturday 1/8/22)

    Status: Completed. WATCH: Post-Deployment Briefing | Re-Watch Live Broadcast

    Webb will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

    Webb will continue to travel to the second Lagrange point (L2) for another two weeks, at which point it will enter a large orbit around the L2 point. The following five months will be used to cool the telescope to operating temperature, fine-tune the mirror alignment, and calibrate the instruments.

  • James Webb Telescope Update Jan 10th fully deployed!

    11:54:58

    JWST will arrive at L2 on January 23rd = 29 days after launch.

    Info for this video from NASA
    NASA achieved another engineering milestone decades in the making! NASA Administrator Bill Nelson said on Twitter. While the journey is not complete, I join the Webb team in breathing a little easier and imagining the future breakthroughs bound to inspire the world.

    James Webb Space Telescope mission engineers confirmed that the observatory's starboard primary mirror wing successfully latched into place at 1:17 p.m. EST (1817 GMT), marking an end to a two-week process that was NASA's most-complicated deployment in space telescope history.

    An elated mission team for NASA's James Webb Space Telescope confirmed that the space observatory is in great shape after a deployment phase that was 100% successful.

    It is a fully deployed telescope ready to perform fantastic science to expand our knowledge, said John Durning, Webb Deputy Project Manager of NASA Goddard.

    Learn more from the mission's project website.

    Up next for the Webb team is a five-month commissioning phase to calibrate the telescope's optics and adjust its mirrors. Webb is currently making its way to its final observing site nearly 1 million miles (1.6 km) from Earth and is due to arrive around Jan. 23.

    To enter orbit around its Lagrange 2 point, Webb will have to perform a short maneuver, but it is expected to go well.

    James Webb Q&A:
    ​It will orbit L2 at about 300 metres per second, ​
    c and d are on the back of the telescope mounting. a and b are on the bus side


    How long will the Webb mission last?
    Webb is designed to have a mission lifetime of not less than 5-1/2 years after launch, with the goal of having a lifetime greater than 10 years. The lifetime is ultimately limited by the amount of fuel used for maintaining the orbit, and by proper functioning in orbit of the spacecraft and instruments. Webb will carry fuel for a 10-year lifetime (with margin); the project will perform mission assurance testing of the flight system to guarantee 5 years of scientific operations starting at the end of the commissioning period 6 months after launch.

    Why not assemble Webb in orbit?
    Various scenarios were studied, and assembling in orbit was determined to be unfeasible.

    We examined the possibility of in-orbit assembly for Webb. The International Space Station does not have the capability to assemble precision optical structures. Additionally, space debris that resides around the space station could have damaged or contaminated Webb’s optics. Webb’s deployment happens far above low Earth orbit and the debris that is found there.

    Finally, if the space station were used as a stopping point for the observatory, we would have needed a second rocket to launch it to its final destination at L2. The observatory would have to be designed with much more mass to withstand this “second launch,” leaving less mass for the mirrors and science instruments.


    How is testing different for Hubble and Webb's mirrors? What did Hubble teach us?
    First, on Webb, we used completely separate sets of measurement tools and techniques for verification than what we used to guide manufacturing. This avoids one error from the Hubble experience where the same tool used for manufacturing was later used for verification.

    In more technical terms, the end-to-end test on Webb's telescope involved passing light through the entire assembled telescope using test point sources of light from precision-placed fiber optics and using reflecting mirrors (three auto-collimating flat test mirrors). This rechecked alignment of all the telescope optics assembled together and demonstrated that the individual primary mirror segments can be aligned to each other, and rechecked the figures of the mirrors.

    Actuator testing and individual mirror segment deployments
    Nominal Event Time: UPDATE: Launch + 18 days (Jan 12)
    Status: Ongoing

    The primary mirror wings are now fully deployed and latched into place, but the individual mirror segments remain in their launch configuration. This operation is a multi-day, multi-step activity to activate and move each of the 18 primary mirror segments and the secondary mirror from their stowed launch configuration to a deployed position ready for alignment.

    The 18 primary mirror segments and secondary mirror are adjustable via six actuators that are attached to the back of each mirror. The primary mirror segments also have an additional actuator at its center that adjusts its curvature. The telescope's tertiary mirror remains stationary. The primary and secondary mirror segments will move a total of 12.5mm, in small increments, over the course of ~10 days to complete each segment's deployment.

    After all individual mirror segment deployments are completed, the detailed optical mirror alignment process begins which is about a 3 month process. In parallel, as temperatures cool enough, instrument teams will turn on their instruments and begin each instrument's commissioning process
