NASA names WFIRST after its first head of astronomy, Nancy Roman

NASA today announced that it has renamed the proposed Wide Field Infrared Survey Telescope (WFIRST) the Nancy Grace Roman Telescope in honor of the agency’s first head of astronomy.

Considered the “mother” of NASA’s Hubble Space Telescope, which launched 30 years ago, Roman tirelessly advocated for new tools that would allow scientists to study the broader universe from space. She left behind a tremendous legacy in the scientific community when she died in 2018.

…When she arrived at NASA, astronomers could obtain data from balloons, sounding rockets and airplanes, but they could not measure all the wavelengths of light. Earth’s atmosphere blocks out much of the radiation that comes from the distant universe. What’s more, only a telescope in space has the luxury of perpetual nighttime and doesn’t have to shut down during the day. Roman knew that to see the universe through more powerful, unblinking eyes, NASA would have to send telescopes to space.

Through Roman’s leadership, NASA launched four Orbiting Astronomical Observatories between 1966 and 1972. While only two of the four were successful, they demonstrated the value of space-based astrophysics and represented the precursors to Hubble. She also championed the International Ultraviolet Explorer, which was built in the 1970s as a joint project between NASA, ESA (European Space Agency) and the United Kingdom, as well as the Cosmic Background Explorer, which measured the leftover radiation from the big bang and led to two of its leading scientists receiving the 2006 Nobel Prize in Physics.

Above all, Roman is credited with making the Hubble Space Telescope a reality. In the mid-1960s, she set up a committee of astronomers and engineers to envision a telescope that could accomplish important scientific goals. She convinced NASA and Congress that it was a priority to launch the most powerful space telescope the world had ever seen.

This is a nice and very fitting gesture to honor one of the many unsung heroes who were important in the history of space astronomy. I just hope that Roman’s telescope doesn’t end up like James Webb’s, so over budget and behind schedule that it destroys all other NASA space telescope projects. Sadly, its track record so far suggests this is what will happen, which is why the Trump administration has been trying to get it canceled.
