![]() ![]() It contained a single instrument, a visible to near-infrared imager/slitless prism spectrometer. The original design of Roman, called WFIRST Design Reference Mission 1, was studied in 2011–2012, featuring a 1.3 m (4.3 ft) diameter unobstructed three-mirror anastigmat telescope. Īs of July 2022, Roman is scheduled to be launched on a Falcon Heavy launch vehicle under a contract specifying readiness by October 2026 in support of a NASA launch commitment of May 2027. On 29 September 2021, NASA announced that Roman had passed its Critical Design Review (CDR), and that with predicted impacts from COVID-19 disruptions, the launch date would be no later than May 2027. ![]() On, NASA Administrator Jim Bridenstine announced that the mission would be named the Nancy Grace Roman Space Telescope in recognition of the former NASA Chief of Astronomy's role in the field of astronomy. Stated objectives include a search for extra-solar planets using gravitational microlensing, along with probing the chronology of the universe and growth of cosmic structure, with the end goal of measuring the effects of dark energy, the consistency of general relativity, and the curvature of spacetime. The Coronagraphic Instrument (CGI) is a high-contrast, small field of view camera and spectrometer covering visible and near-infrared wavelengths using novel starlight-suppression technology. The Wide-Field Instrument (WFI) is a 300.8-megapixel multi-band visible and near-infrared camera, providing a sharpness of images comparable to that achieved by the Hubble Space Telescope over a 0.28 square degree field of view, 100 times larger than imaging cameras on the Hubble. The Roman Space Telescope is based on an existing 2.4 m (7.9 ft) wide field of view primary mirror and will carry two scientific instruments. On 17 February 2016, WFIRST was approved for development and launch. Roman was recommended in 2010 by the United States National Research Council Decadal Survey committee as the top priority for the next decade of astronomy. The Nancy Grace Roman Space Telescope (shortened as Roman or the Roman Space Telescope, and formerly the Wide-Field Infrared Survey Telescope or WFIRST) is a NASA infrared space telescope currently in development and scheduled to launch by May 2027. This visualization follows the Roman Space Telescope on its trajectory to the Sun–Earth Lagrange point L2. October 2026 (contracted) - May 2027 (commitment) Ġ.48–2.30 μm ( Blue to Near-infrared) Wide-Field Infrared Survey Telescope (WFIRST) You can try whatever you want though- creativity has no limit.Rendered model of the Roman Space Telescope in May 2020 Instead, I traced out the lines and added some sparkle to the stars with some red, orange, and green color pencils. I didn't use glitter glue on the second tube because I thought the glitter might rub off anyway whenever I slid the tube out or in after the glue dries. I also used I different colors of glitter glue such as red, sliver, gold, indigo, and magenta to make it shine. I also used orange, pink, and yellow construction paper to make planets, moons and stars. I covered the whole thing with dark blue colored paper, then did the rims with rings of violet paper. Next, you can add a light sprinkle of glitter, or paper cut outs of stars, comets, planets, glittery rainbows of galaxies- anything else you'd like to personalize or make your telescope look cooler. I used dark blue and purple colored paper to give a space-like feeling, like I said before. Here's the fun bit! Use colored paper, wrapping paper, or paint to paint your tubes if you haven't before. That way, when I slide the back tube in all the way, a little sticks out, and it looks a bit nice, while when I stretch it out, it's a little longer than I would need to find the focal point, but at the same time isn't too long and very hard to slide around and find. ![]() I cut my front tube 23 cm long, and the back one 25 cm. ![]() Unless your front tube is longer than the distance between the two glasses, you don't need to cut it shorter, but it'll probably look nicer if it's not too awkward and long. You want your tubes to be a bit longer than that, but not too long it's an awkward length and is too hard to find the focal point at the end when your telescope is finished. That's the focal point.Ĭonsider how far apart the glasses are at the focal point. Bring the bigger glass closer and farther until whatever's in front of you becomes the clearest it can be. Looking through the smaller glass, place the bigger one far out in front of you so you're looking through both at the same time (make sure there's something in front of you to see or read). ![]()
