By 2027, the Nancy Grace Roman Space Telescope – or Roman Space Telescope (RST), for short – will take to space and build on the legacy of the venerable Hubble Space Telescope (HST). Combing a large primary mirror, a camera as sensitive as its predecessors, and next-generation surveying capabilities, Roman will have the power of “One-Hundred Hubbles.” It’s little wonder then why the telescope is named after Dr. Roman (1925 – 2018), NASA’s first Chief Astronomer and the “Mother of Hubble.”
As part of its journey towards realization, this next-generation space telescope recently passed a crucial milestone. This would be the all-important Mission Critical Design Review (CDR), signaling that all design and developmental engineering work is complete. With this milestone reached, the next-generation space telescope is now ready to move from the conceptual stage into the fabrication and assembly phase.

We have discovered thousands of exoplanets in recent years, including some that are Earth-sized and potentially habitable. But we haven’t seen many of those worlds. Most of the exoplanets we’ve found have been discovered using the transit method, which involves watching the brightness of a star dip as a planet passes in front of it. We can learn the size and sometimes the mass from these dips, but we have no idea what the world looks like, or whether it has a breathable atmosphere.

In November of 2021, the James Webb Space Telescope (JWST) will make its long-awaited journey to space. This next-generation observatory will observe the cosmos using its advanced infrared suite and reveal many never-before-seen things. By 2024, it will be joined the Nancy Grace Roman Space Telescope (RST), the successor to the Hubble mission that will have 100 times Hubble’s field of view and faster observing time.
These instruments will make huge contributions to many fields of research, not the least of which is the discovery and characterization of extrasolar planets. But even with their advanced optics and capabilities, these missions will not be able to examine the surfaces of exoplanets in any detail. However, a team of the UC Santa Cruz (UCSC) and the Space Science Institute (SSI) have developed the next best thing: a tool for detecting an exoplanet surface without directly seeing it.

In 2025, the Nancy Grace Roman space telescope will launch to space. Named in honor of NASA’s first chief astronomer (and the “Mother of Hubble“), the Roman telescope will be the most advanced and powerful observatory ever deployed. With a camera as sensitive as its predecessors, and next-generation surveying capabilities, Roman will have the power of “One-Hundred Hubbles.”
In order to meet its scientific objectives and explore some of the greatest mysteries of the cosmos, Roman will be fitted with a number of infrared filters. But with the decision to add a new near-infrared filter, Roman will exceed its original design and be able to explore 20% of the infrared Universe. This opens the door for exciting new research and discoveries, from the edge of the Solar System to the farthest reaches of space.

NASA’s Nancy Grace Roman Space Telescope is getting closer and closer to its launch date in 2025. This Hubble-class wide-field infrared telescope is going to help astronomers discover the nature of dark energy, discover planets, and perform large area surveys of the night sky.
But even with its power, the telescope will be limited in its ability to examine planets.
A team of engineers is proposing to fly a follow-on mission to Nancy Grace: a Starshade. This petal-shaped spacecraft could fly in formation with the telescope, blocking the light from stars, and helping it see the fainter planets nearby.
An exceptional telescope gets an upgrade? That seems like a win-win.

Remember the Hubble Deep Field? And its successor the Hubble Ultra Deep Field? We sure do here at Universe Today. How could we forget them?
Well, just as the Hubble Space Telescope has successors, so do two of its most famous images. And those successors will come from one of Hubble’s successors, NASA’s Roman Space Telescope.

If a solar system is a family, then some planets leave home early. Whether they want to or not. Once they’ve left the gravitational embrace of their family, they’re pretty much destined to drift through interstellar space forever, unbound to any star.
Astronomers like to call these drifters “rogue planets,” and they’re getting better at finding them. A team of astronomers have found one of these drifting rogues that’s about the same mass as Mars or Earth.

The Nancy Roman Telescope has reached another milestone in its development. NASA has announced that the space telescope’s primary mirror is now complete. The 2.4 meter (7.9 ft) mirror took less time to develop than other mirrors because it wasn’t built from scratch. It’s a re-shaped and re-surfaced mirror that came from the National Reconnaissance Office.

In May of 2020, NASA made the decision to give the next-generation Wide Field Infrared Space Telescope (WFIRST) a proper name. Henceforth, it would be known as the Nancy Grace Roman Space Telescope (or Roman Space Telescope) in honor of NASA’s first Chief Astronomer and a woman’s who tireless work in the field of STEMs research led to the creation of the Hubble Space Telescope – hence her nickname, the “mother of Hubble”).
However, in recent months, the budget environment has not been too favorable to the Roman Space Telescope (RST), as well as education-related programs. But thanks to a recent bill considered by the House Appropriations Commitee, funding has been restored to five NASA science missions and projects – including the RST – that the administration’s budget proposal sought to cancel for the coming year.

In the mid-2020s, NASA’s next-generation Wide Field Infrared Survey Telescope (WFIRST) will take to space. With unprecedented resolution and advanced instruments, it will build on the foundation established by the venerable Hubble Space Telescope – which celebrated its 30th anniversary this year! In anticipation of all it will accomplish, NASA decided that the WFIRST needs a proper name, one that honors its connection to Hubble.
This week, NASA announced that henceforth, the WFIRST mission will be known as the Nancy Grace Roman Space Telescope (or Roman Space Telescope for short) in honor of Dr. Nancy Grace Roman (who passed away in 2018). In addition to being NASA’s first Chief Astronomer, she was also a tireless educator and advocate for women in STEMs whose work paved the way for space telescopes – leading to her nickname “the mother of Hubble.”
