NASA’s new Nancy Grace Roman Space Telescope is scheduled to launch on August 30, featuring advanced wide-field imaging and experimental coronagraph technology.
Key facts
- •The Nancy Grace Roman Space Telescope is scheduled to launch on August 30 from Cape Canaveral, Florida.
- •The telescope's Wide Field Instrument allows it to capture images 100 times larger than Hubble's field of view.
- •The mission is designed to last five years, though NASA notes that space telescope missions are frequently extended.
- •The onboard coronagraph uses adaptive optics to attempt the direct imaging of planets orbiting other stars.
- •NASA compares the difficulty of the coronagraph's task to photographing a firefly next to a floodlight from across the country.
NASA is set to launch the Nancy Grace Roman Space Telescope from Cape Canaveral, Florida, on August 30. Named after NASA’s first chief of astronomy, the observatory is designed to work alongside the James Webb and Hubble space telescopes to investigate the universe in infrared wavelengths. The mission aims to map dark matter distribution and measure the effects of dark energy with unprecedented precision.
By the numbers
Wide-Field Imaging Capabilities
The Roman telescope utilizes a Wide Field Instrument to capture images with the same resolution as the Hubble Space Telescope but over an area 100 times larger. This capability makes the observatory 1,000 times faster at gathering data than its predecessor. Over a five-year primary mission, the telescope is expected to observe approximately 12 percent of the sky, potentially revealing cosmic history dating back to 2 billion years after the Big Bang.
Experimental Coronagraph Technology
In addition to its wide-field surveys, the telescope carries an experimental coronagraph designed to directly image planets orbiting other stars. The instrument acts as a sunshade to block light from bright stars, allowing the telescope to detect faint reflections from orbiting planets. To achieve this, the coronagraph employs sophisticated adaptive optics—technology that deforms mirrors to cancel out light distortions—to distinguish planets from the glare of their host stars.
