Agham · Roman Telescope LaunchNASA's Roman Telescope Launches on Mission to Map the Hidden UniverseIsinulat Setyembre 7, 2026 nang 9:22 PM UTCManoodTranskripsyon0:00Roman is a million miles out, its field of view a hundred times wider than Hubble's.0:05NASA expects it to uncover on the order of 100,000 new worlds and to map dark energy0:10across sweeping swaths of the universe.0:12But the hardware that turns it into a working telescope is still ahead.0:16Roman lifted off August 30th at 7.26 a.m.0:19Eastern from Launch Complex 39A at the Kennedy Space Center aboard a SpaceX Falcon0:24Heavy.0:25Thirty-one minutes later, the upper stage separated and ground teams had telemetry0:29within about seven minutes.0:31Solar arrays, the sun shield, and the lower instrument sunshade all deployed about0:35an hour and 23 minutes into flight.0:37NASA has confirmed the observatory is healthy and on course toward a quasi-halo0:42orbit around the Sun-Earth L2 point, about a million miles from Earth.0:46The number this mission hinges on is its field of view.0:49Roman's primary mirror is 2.4 meters across, identical to Hubble's, but a single0:54Roman image captures a patch of sky at least 100 times larger than one from Hubble,0:58at Hubble-like resolution.1:00Its wide-field instrument carries an active field of view of 0.281 square degrees,1:05about 0.8 by 0.4 degrees, so one image covers an area larger than the apparent size1:11of the full moon.1:12A separate figure, sometimes cited, compares Roman's infrared field of view,1:16specifically against Hubble's infrared cameras, at about 200 times.1:20That is an instrument-to-instrument measure.1:22NASA's standard headline comparison is the 100x field-of-view figure.1:26Both figures trace to the same underlying capability.1:29Roman is designed to survey the universe roughly a thousand times faster than1:32Hubble, and over its five-year prime mission, it is expected to image about 50 times1:37as much sky as Hubble captured across its roughly 30 years in orbit.1:40The mission's total life cycle cost is about $4.3 billion.1:45The prime mission runs five years with a possible five-year extension, and fuel is1:49the main consumable determining how long it operates.1:52NASA cites nearly 6,000 known planets as the context for its exoplanet work.1:57The launch era count put it near 6,200.2:00and expects Roman to uncover on the order of 100,000 new worlds through its2:03microlensing, transit, and coronagraph instruments.2:07Right now, the observatory is working through a staged commissioning sequence.2:12The first 10 days cover the remaining deployments in outgassing, the high-gain2:15antenna, the deployable aperture cover that acts as a visor-like sunshade, a first2:20mid-course correction planned about a day after launch with a possible second about2:23three days later, the coronagraph powering on in the coming days, and the wide-field2:27instrument activating a few weeks into the cruise.2:30That is followed by roughly 30 days of spacecraft checkout and about 45 days of2:34instrument commissioning, with full commissioning wrapping up around the 90-day2:38mark.2:39First public images are targeted for early 2027, with science operations beginning2:44around that time.2:44Roman complements rather than replaces the deep, narrow field observing of James2:49Webb and Hubble, where those telescopes peer closely at a single selected target.2:54Roman sweeps across a wide swath of the sky in one frame, which is what makes it a2:58survey instrument.3:00What remains unresolved is the hardware still ahead.3:03Roman has cleared its early deployments and been confirmed healthy, but it must3:07still deploy its high-gain antenna and aperture cover, execute its mid-course3:11corrections, and complete the roughly 90-day checkout before its instruments come3:16online, and it can return those first images.3:19Until commissioning finishes, science operations and the survey that could rapidly3:23reshape maps of the universe do not begin.Basahin ang artikuloTakbo ng kuwento sa panahonHeyDexAng maikling video ↗
