In the Decadal Survey on Astronomy and Astrophysics 2020, the National Academy of Sciences recommended to NASA a series of competed probe-class missions, including one with far-infrared (FIR) imaging or spectroscopy capabilities. The Academy also recommended that technology development for a future flagship-class FIR mission commence. Both types of missions would require cryogenic telescopes with unprecedented sensitivities and mapping speeds to enable FIR science. Telescopes with these capabilities would allow the astronomical community to address a wide range of scientific objectives such as measuring the masses of protoplanetary disks; tracking the role of water, ice, and volatiles in planet formation; and investigating the interplay between the interstellar medium and star formation across the Milky Way. A cryogenic FIR observatory would also allow scientists to diagnose the state of gas and its radiation environment in nearby galaxies, including outer galaxy disks and extra-planar material associated with feedback and gas accretion. In addition, observations made with these advanced telescopes would allow scientists to study the evolution of galaxies and the matter they are made of throughout the history of the universe—from the formation of the first dust clouds, to star-forming galaxies at the cosmic noon (a time when significantly more stars per time unit were formed than today). Such studies could also include detailed investigations of the matter that our own galaxy, the Milky Way, is made of. Observing light at the wavelengths invisible to our eyes, these observatories will be able to see through the layers of matter that block the light in the visible part of the electromagnetic spectrum. Even regions where foreground matter completely blocks the view (like the bricks of a house that will not let see you what is inside) will be visible in the far-infrared. These new telescopes will be able to observe massive black holes that are embedded in the dense central regions of many galaxies. Such observations will allow astronomers to determine how the creation of black holes proceeded throughout the history of the universe. To make these types of observations, NASA’s future telescopes need robust, high-sensitivity, kilopixel-format arrays that operate over the entire far-IR spectrum. Previously, some of the key technologies needed for these arrays were demonstrated on the High-resolution Airborne Wideband Camera (HAWC+) on the Stratospheric Observatory for Far-Infrared Astronomy (SOFIA). Those detectors provided excellent performance for suborbital far-IR applications, but their production was very labor intensive with relatively low fabrication yields. The remaining major technologies required to enable future FIR space-based telescopes are: (a) robust detector array architectures with approximately 100,000 individual pixels and (b) integrated readout multiplexers that can meet the ultra-low noise requirements of space missions. The NASA Astrophysics Division’s Strategic Astrophysics Technology (SAT) Program is sponsoring a team from NASA’s Goddard Space Flight Center (GSFC) in Greenbelt, Maryland, and the National Institute of Standards and Technology (NIST) in Boulder, Colorado to address this need. Led by Dr. Johannes Staguhn at the Johns Hopkins University/GSFC, the team is maturing and streamlining the processing required to produce arrays with large numbers of pixels (10,000) that can be tiled to deliver the desired 100,000 pixel count. The project will advance the technology to Technical Readiness Level 5 (defined as component and/or breadboard validation in a relevant environment), an important step towards maturation of technologies for eventual space flight. Enabling a Kilopixel Detector Array The team has successfully produced all the individual components required for the new detectors. First, the team developed detector wafers that could be bonded together to produce a detector with the required 100,000 pixels. The figure below shows a picture of the detector wafer (left image), which consists of 1024 individual pixels. The image on the right shows a zoomed-in view of part of an individual pixel. Each pixel contains one superconducting detector, which is a Transition Edge Sensor (TES) made from aluminum manganese (AlMn). Part of the absorber mesh, which is tuned to the electromagnetic radiation coming from the telescope, can also be seen in the righthand image.

Tina Hesman Saey’s estimation, “closer to 300 years.” From February to April 2020, the Science News senior molecular biology writer had produced a flurry of stories on the new coronavirus that wove together findings from dozens of scientific papers and reports. Her hours were long and stress levels high. But the science wasn’t slowing down, so neither could she.

“We’re in a hyperdrive situation,” Saey said in May 2020, reflecting on her pandemic reporting. “It’s amazing how fast the science is moving.” In mere months, researchers had completely overhauled their understanding of how the SARS-CoV-2 virus infiltrates the body, and vaccines were already in the works. Readers were counting on Saey and her Science News colleagues to sift through the deluge of information pouring out of labs across the world. “The information that they get from us can really help them make life-or-death decisions,” Saey said.

Since then, Saey and other Science News reporters have cranked out hundreds of stories on SARS-CoV-2’s basic virology, new variants, vaccine rollouts and more. To boost public understanding of the new coronavirus, Science News has freely offered its COVID-19 stories to local and nonprofit news organizations since April 2020

Science News’ push to get reliable reporting in front of as many eyes as possible harks back to before the publication was even a magazine. A little over a century ago, Science News got its start as Science News Bulletin — the first syndicated news specializing in science.

“There certainly had been media coverage of science before,” says Bruce Lewenstein of Cornell University, who studies science communication. But that coverage was more sporadic and often plagued with sensationalism and superstition.

Newspaper magnate Edward W. Scripps, who believed that a functioning democracy required a science-savvy public, wanted to get more accurate, reliable science news in the public eye. To do that, Scripps teamed up with his zoologist friend William E. Ritter to form a new organization for science communication in 1921. Based in Washington, D.C., Science Service — now known as the Society for Science — was funded by Scripps and overseen by a board of 15 scientists and journalists. That board of trustees included famed astronomer George Ellery Hale and Edwin Gay, president of the New York Evening Post.
