However, because the project will breach its cost cap, the U.S. The valuable recommendations of the IRB support our efforts towards mission success we expect spectacular scientific advances from NASA’s highest science priority.” “Webb is poised to answer those questions, and is worth the wait. “The more we learn more about our universe, the more we realize that Webb is critical to answering questions we didn’t even know how to ask when the spacecraft was first designed,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. The agency agrees with the review board’s expert guidance on decisive steps necessary to safeguard and complete the telescope’s development. The report includes several recommendations for moving forward, some of which NASA has already initiated. The board also reaffirmed Webb’s significant complexity, incredible scientific potential, and importance to astrophysics. “Ensuring every element of Webb functions properly before it gets to space is critical to its success.” See Also leadership in astronomy and astrophysics,” said Tom Young, the chair of the review board. “Webb should continue based on its extraordinary scientific potential and critical role in maintaining U.S. The project will breach its $8.8 billion cost cap and require additional funds to be authorized by Congress.Ībove all, though, the IRB stressed the need to continue and see JWST through to launch and operation.The telescope’s launch is slipping at least another year to NET 2021.Providing an update on the results of the Independent Review Board (IRB) and ongoing schedule for the James Webb Space Telescope – the agency’s much heralded follow-on observatory of the Hubble Space Telescope – NASA today confirmed that: JWST is planned for launch on a Arianespace Ariane 5 rocket from the Guiana Space Centre in Kourou, French Guiana in South America. In fact, JWST’s infrared capabilities are expected to allow scientists and observers to see back in time to the formation of the first galaxies just a few hundred million years after the Big Bang. This, coupled with the fact that the universe is expanding, means that light from the earliest stars and galaxies becomes red-shifted as it travels toward Earth.īecause of this, these early-universe objects are easier to observe if viewed in the mid-infrared – as JWST will do. The more distant an object is from Earth, the younger it appears because its light takes a very long time to reach our observatories. JWST is also far better suited to observe the cosmological redshift. NASA’s James Webb Space Telescope, set for launch NET 2021 Observations conducted via mid-infrared better penetrate dust and gas and will allow JWST to see dimmer, cooler objects than Hubble and the Spitzer Space Telescope can. Unlike Hubble, which observes in the near ultraviolet, visible, and near infrared spectra, JWST will observe the long-wavelength (orange to red) spectrum in the mid-infrared (0.6 to 27 μm) range – allowing JWST to see high redshift objects too old and distant for Hubble and other telescopes to observe. Other goals include understanding the formation of stars and planets as well as direct imaging of exoplanets and novas. One of the telescope’s major goals is observing some of the most distant events and objects in the universe, like the formation of the first galaxies – targets that are beyond the reach of current ground- and space-based observatories. At 100 times the power of the Hubble Space Telescope, JWST will provide unprecedented resolution and sensitivity of the farthest and oldest objects of the universe and will enable a broad range of investigations across the fields of astronomy and cosmology. While the delays currently form the conversation surrounding the James Webb Space Telescope (JWST), it is important to remember the benefits to science and astronomy the telescope will offer. Coming just three months after a year-long delay to 2020, NASA now says the telescope will not be ready to launch until 2021 at the earliest and that the project will breach its $8.8 billion USD cost cap. Following an Independent Review Board report on the James Webb Space Telescope project, NASA has announced a further delay to the telescope’s anticipated launch.
