Expected to launch in the mid-2020s, this instrument will give astronomers a clearer and more expansive view of the universe than ever before, with the ultimate goal of answering some of the biggest mysteries in space. The WFIRST’s primary mirror will be 7.9 ft in diameter, the same size as the primary mirror on the Hubble Space Telescope. Scientists will also use WFIRST to test several theories about why research indicates the Universe is expanding at increasing speed. JoAnna Wendel - Space.com contributor This artist’s illustration depicts the Wide Field Infrared Survey Telescope in space. That bent light magnifies the lensing star, making it appear much bigger to us on Earth. Yes, there's a video. “Looking at a large fraction of the sky allows you to get a more complete accounting of, for example, the stars in the Large Magellanic Cloud, which is the nearest galaxy to us, or the stars in the galactic bulge. Wide Field Infrared Survey Telescope (WFIRST) (2020), Article: "Printing Space: Using 3D Printing", 3D Models Put Students in Touch with Planets. As the primary instrument, the Wide Field Instrument will measure light from a billion galaxies over the course of the mission lifetime. On February 17, 2016, WFIRST was formally designated as a mission by NASA. More information in the following paper: The Wide Field Infrared Survey Telescope: WFIRST, James C. Green, Univ. Thank you for signing up to Space. Please deactivate your ad blocker in order to see our subscription offer. That same image, when recreated by WFIRST would require only two images and three hours. Conclusion Note – not a science talk, very brief science section. Its observations also supported the discovery of the first Y Dwarf and Earth trojan asteroid. WFIRST is the top-ranked large space mission in the 2010 New Worlds, New Horizon Decadal Survey … The CI will employ deformable mirrors and special masks to block incoming light from a star, enabling the team to view distant, dim planets 1 billion times fainter than its star. Because exoplanets are so much dimmer than the stars they orbit, they're incredibly difficult to spot by just taking pictures. One technique WFIRST will use is called microlensing. By WFIRST was recommended in 2010 by United States National Research Council Decadal Survey committee as the top priority for the next … WFIRST's work will include creating a precise map of the change in the distribution of galaxies over time, looking for supernovas and measuring their distance away from us, and measuring the shape of very large galaxies and galaxy clusters. Educator-astronaut talks to 'kids at heart' for online talk Tuesday. Enter WFIRST. The Wide Field Infrared Survey Telescope (WFIRST) is a NASA infrared space observatory currently under development. The telescope will carry two instruments on a primary mission now planned to last 5 years—the Wide Field Instrument (WFI) and the Coronagraph Instrument (CI). “With Hubble you get these really tantalizing glimpses of very complex nearby systems. The Wide Field Infrared Survey Telescope (WFIRST) is a NASA observatory designed to perform wide-field imaging and surveys of the near-infrared sky. Gaudi is a principal investigator on the WFIRST Formulation Science Working Group. With a slew of calculations, scientists can then figure out such a planet's mass, orbit and orbital period around the lensing star. WFIRST was the top priority large space mission in the 2010 Decadal Survey of Astronomy and Astrophysics by the National Research Council of the National Academy of Sciences. WFIRST will expand that search to look for planets as far away as we can imagine — thousands of light-years away, near the center of the Milky Way galaxy. The primary instrument is the WFI, an infrared imaging and spectrometry device with 18 sensors, each 4,096 x 4,096-pixels, giving WFIRST 100 times the capacity of Hubble. It was re-activated in 2013. The Wide Field Instrument will provide a field of view of the sky that is 100 times larger than images provided by Hubble. When one star in our foreground passes near a background star (from our perspective), the background (or source) star's light is bent around the foreground (or lensing) star. WFIRST was the top priority large space mission in the 2010 Decadal Survey of Astronomy and Astrophysics by the National Research Council of the National Academy of Sciences. Conclusion Note – not a science talk, very brief science section. The Wide Field Infrared Survey Telescope (WFIRST) is a 2.4m telescope equipped with a large area, 300-megapixel, near-infrared camera for imaging and slitless spectroscopy and an on-axis, visible-light coronagraph for imaging, polarimetry, and low-resolution spectroscopy of circumstellar disks and nearby giant exoplanets. To demonstrate the amazing capabilities of WFIRST, the team created a simulation of an iconic 2015 image of the Andromeda galaxy created by joining together 400 Hubble images taken over more than three years. And if that lensing star has planets, those planets also perceptibly bend the source star's light. NASA’s Wide Field Infrared Survey Telescope (WFIRST) mission will help uncover some of the biggest mysteries in the cosmos. With WFIRST, all of a sudden you can cover the whole thing without spending lots of time,” said Williams, in a NASA press release. As background information for Astro2020 white papers, this article summarizes the current design and anticipated performance of WFIRST. The current design of the mission makes use of an existing 2.4-meter telescope, which is the same size as the Hubble Space Telescope. Correction: This article was updated on July 17, 2019 to add that L3Harris is also involved with development and construction of WFIRST. Receive mail from us on behalf of our trusted partners or sponsors? WFIRST will have Hubble’s precision with 100 times the field of view.

The current design of the mission makes use of an existing 2.4-meter telescope, which is the same size as the Hubble Space Telescope. Future US, Inc. 11 West 42nd Street, 15th Floor, So, you can do a much more complete accounting in a much shorter amount of time,” said Scott Gaudi, an exoplanet astronomer at The Ohio State University, in a NASA video. Visit our corporate site. As background information for Astro2020 white papers, this article summarizes the current design and anticipated performance of WFIRST. The telescope will feature a 2.4-meter-wide (7.8 feet) mirror and a 300-megapixel camera, allowing the observatory to capture in one shot an area 100 times larger than NASA's Hubble Space Telescope can, with identical high resolution. All of these measurements will help scientists understand how dark energy has evolved, which is key to understanding why the expansion of the universe seems to be accelerating. The telescope will perform a number of measurements to help scientists study the evolution of dark energy since the Big Bang. Space calendar 2020: Rocket launches, sky events, missions & more! There was a problem. Fast Infrared Exoplanet Spectroscopy Survey Explorer Launch Date: April 28, 2003 The Galaxy Evolution Explorer was an orbiting space telescope designed to observe the universe in ultraviolet wavelengths to measure the history of star formation in the universe. The Wide Field Infrared Survey Telescope (WFIRST) is a NASA observatory designed to perform wide-field imaging and surveys of the near-infrared sky. Please refresh the page and try again. Using this technique, WFIRST can study an exoplanet's structure, composition or even atmospheric chemistry — aspects of a planet that scientists need to study to understand whether that world is potentially habitable. Through its world-class training curriculum, knowledge-sharing initiatives, development resources, and strategic communications, APPEL Knowledge Services helps ensure NASA’s technical workforce has the skills and knowledge needed to advance mission success. The telescope is being repurposed for scientific use for NASA by L3Harris, an aerospace technology company, and Ball Aerospace, a spacecraft and payload developer that has contributed technology to Hubble and NASA's Spitzer Space Telescope. Beyond helping us answer some of humanity's most enduring questions, WFIRST will also help scientists spot planets orbiting other stars in our galactic neighborhood. “The particular thing I’m interested in using WFIRST for is to actually do a statistical census of planetary systems in our galaxy.”, The wide field instrument includes filters that provide an imaging mode covering 0.48 — 2.0 μm, and two slitless spectroscopy modes.Credit: NASA.
