News of this milestone was very first shared by B. Scott Gaudi, a Professor with the Department of Astronomy of the Ohio State Unversity (OSU), on Sept. 28th by means of Twitter. Prior to rejoining the Dept. of Astronomy at OSU (where he earned his graduate degree), Gaudi was a Menzel postdoctoral fellow with the Theoretical Astrophysics Division at the Harvard-Smithsonian Center for Astrophysics (CfA), a Hubble Fellow, and a member of the Institute for Advanced Study.
By 2027, the Nancy Grace Roman Space Telescope– or Roman Space Telescope (RST), for short– will take to space and develop on the legacy of the venerable Hubble Space Telescope (HST). Combing a big main mirror, a camera as delicate as its predecessors, and next-generation surveying capabilities, Roman will have the power of “One-Hundred Hubbles.” Its little wonder then why the telescope is called after Dr. Roman (1925– 2018), NASAs first Chief Astronomer and the “Mother of Hubble.”
As part of its journey towards awareness, this next-generation area telescope recently passed an essential milestone. This would be the critical Mission Critical Design Review (CDR), signaling that all design and developmental engineering work is total. With this milestone reached, the next-generation space telescope is now all set to move from the conceptual phase into the fabrication and assembly phase.
By 2027, the Nancy Grace Roman Space Telescope– or Roman Space Telescope (RST), for short– will take to area and construct on the tradition of the venerable Hubble Space Telescope (HST). Im delighted to share that the Nancy Grace Roman Space Telescope @NASARoman simply passed its Mission Critical Design Review.” Im thrilled to share that the Nancy Grace Roman Space Telescope @NASARoman simply passed its Mission Critical Design Review,” tweeted Gaudi. During the 1960s, Roman was the first Chief of Astronomy in NASAs Office of Space Science, promoting relentlessly for NASA programs and females in the STEAM fields. Roman will work in tandem with other next-generation observatories, like the James Webb Space Telescope (which is arranged to release in November).
” Im excited to share that the Nancy Grace Roman Space Telescope @NASARoman just passed its Mission Critical Design Review,” tweeted Gaudi. “This is a really essential turning point for Roman. Its the conclusion of 5.5 years of effort since Roman became an official @NASA task in Feb 2016.”
This external review comes after engineers at NASAs Goddard Space Flight Center finished their evaluation of the RST and were pleased that it can proceed to the next phase, consisting of major fabrication, screening, assembly, and integration. The completion of the Mission CDR is also crucial to securing Congressional approval for financing, without which no mission can proceed through development. As Julie McEnery, the RST senior job scientist at NASA Goddard described everything in a recent NASA press statement:
” After seeing our extensive hardware screening and advanced modeling, an independent evaluation panel has validated that the observatory we have actually created will work. We understand what it will look like and what it will be capable of. Now that the foundation is laid, the team is thrilled to continue structure and checking the observatory theyve envisaged.”
The RST is part of a handful of proposed observatories that will take over from NASAs Great Observatories, that include the age-old Hubble Space Telescope (HST), the Spitzer Space Telescope (SST), the Chandra X-ray Observatory, and the Compton Gamma-Ray Observatory (CGRO). Once it is functional, the RST will peer across huge stretches of area and time to survey the infrared Universe, measure the impact of Dark Matter and Dark Energy, and discover many astronomical objects.

The original principles for the RST were introduced in between 2009 and 2010 as part of the Astro2010 Decadal Survey. In action to requests from different Decadal panels, scientists proposed numerous ideas for a next-generation big objective, like the Near-Infrared Sky Surveyor (NISS), the Microlensing Planet Finder (MPF), and the Joint Dark Energy Mission (JDEM)/ Omega. In 2016, these concepts were folded over into a single proposition, called the Wide-Field Infrared Survey Telescope (WFIRST).
In May of 2020, corresponding with the thirtieth anniversary of the HST, NASA chose to relabel the WFIRST after Nancy Grace Roman. During the 1960s, Roman was the very first Chief of Astronomy in NASAs Office of Space Science, advocating tirelessly for NASA programs and ladies in the STEAM fields. In the mid-1960s, she developed a committee of engineers and astronomers to envision a space telescope efficient in accomplishing numerous scientific missions.
Her efforts were realized in 1990 with the launch of Hubble, which would result in a transformation in astronomy. These efforts and achievements are what resulted in the label “the Mother of Hubble.” Because this telescope is the direct successor to the HST (but with far greater surveying power), Dr. Nancy Grace Roman was the natural option when NASA chose to provide the WFIRST an appropriate name.
As Gaudi described, all NASA objectives need to undergo multiple vital style evaluations, but the most crucial is the Mission CDR. In the case of the RST, the evaluation needed 6 days, as the hundreds of engineers and service technicians involved presented over 1800 charts and volumes of information on the design.

Said Jackie Townsend, deputy task manager for the Roman Space Telescope at NASA Goddard:
” With this evaluation total, we enter the amazing stage where we will assemble and check the Roman hardware that we plan to fly. When all our flight hardware is prepared in 2024, well hold the System Integration Review and incorporate the Roman observatory. Finally, well check the entire observatory in environments that replicate launch and our orbit to make sure Roman will work as designed.” The mission is slated to release no behind May 2027.”
With the very same resolution as Hubble in the infrared band and a field of view 200 times bigger, Roman will achieve what it would take Hubble centuries to do in five years. It is likewise anticipated to play a major function in finishing the census of exoplanets, including rocky worlds that orbit within their stars circumsolar habitable zones (aka.
By observing deep space from its earliest epochs, Roman will likewise help shine a light on Dark Matter and Dark Energy. Whereas Dark Matter represent 85% of deep spaces mass (instead of “luminescent,” or normal, matter), Dark Energy is the evasive force that is believed to be responsible for how cosmic expansion is accelerating. Together, they consist of 95% of the total mass– energy content of the Universe.
By seeing cosmic development unfold over the past ~ 13.8 billion years, astronomers want to observe how these forces impacted that development. Roman will work in tandem with other next-generation observatories, like the James Webb Space Telescope (which is arranged to release in November). While Roman will determine new items, galaxies, stars, and worlds, James Webb will conduct follow-up observations with its advanced IR suite.
Another transformation in astronomy will happen in the coming years. With Romans mission CDR complete, we are another step closer to seeing it unfold!
