Lunar crater radio telescope: Illuminating the cosmic dark ages

After years of development, the Lunar Crater Radio Telescope (LCRT) project has been awarded $500,000 to support additional work as it enters Phase II of NASA's Innovative Advanced Concepts (NIAC) program. While not yet a NASA mission, the LCRT describes a mission concept that could transform humanity's view of the cosmos.
The LCRT's primary objective would be to measure the long-wavelength radio waves generated by the cosmic Dark Ages—a period that lasted for a few hundred million years after the Big Bang, but before the first stars blinked into existence. Cosmologists know little about this period, but came the answers to some of science's biggest mysteries may be locked in the long-wavelength radio emissions generated by the gas that would have filled the universe during that time.
"While there were no stars, there was ample hydrogen during the universe's Dark Ages—hydrogen that would eventually serve as the raw material for the first stars," said Joseph Lazio, radio astronomer at NASA's Jet Propulsion Laboratory in Southern California and a member of the LCRT team.
NASA's On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission ready for spacecraft build

NASA is one step closer to robotically refueling a satellite and demonstrating in-space assembly and manufacturing thanks to the completion of an important milestone.
In April 2021, NASA and Maxar Technologies successfully completed the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission spacecraft accommodation Critical Design Review (CDR). This milestone demonstrates that the maturity of the design for the OSAM-1 spacecraft bus is appropriate to support proceeding with fabrication, assembly, integration, and testing.
OSAM-1 will, for the first time ever, robotically refuel a U.S. government satellite not designed to be serviced. The spacecraft will consist of a servicing payload, provided by NASA's Goddard Space Flight Center in Greenbelt, Maryland, with two robotic arms that will be attached to the spacecraft bus. The bus will also incorporate a payload called Space Infrastructure Dexterous Robot (SPIDER) that will demonstrate in-space assembly and manufacturing. SPIDER will use a third robotic arm to assemble a communications antenna and an element called MakerSat built by Tethers Unlimited to manufacture a beam. The spacecraft bus and SPIDER are being built by Maxar Technologies.
Image: NASA's Lucy high gain antenna up close

Lucy's epic journey to observe Jupiter's Trojan asteroids requires a reliable communications link back to Earth, and so the spacecraft is outfitted with a 6.5-ft. (2-meter)-wide high gain antenna for this task.
Designed and built by Lockheed Martin, this same style antenna has been used to return science data from Mars and transfer back photos of asteroid Bennu. Lucy's antenna will send back the first-ever close up images and spectra of Trojan asteroids.
The signal from the antenna will also help determine the mass of these never-before-visited space objects revealed by tiny changes in frequency caused by the Doppler effect.
