From UPI: NASA scientists, as well as astronomers around the world, plan to install lunar observatories in the next few years to peer into the universe's ancient past -- just after the Big Bang.

Science equipment headed to the moon already includes a spectrometer built for launch in early 2022, known as ROLSES, which will study how sunlight charges the slight lunar atmosphere.

The acronym includes the word "sheath," which refers to a field of energy created by sunlight reflecting from the bright lunar surface. And NASA scientists are formulating plans for observatories on the far side of the moon, where darkness and clear sightlines could yield new discoveries about the universe before stars existed.

One bold plan to build a telescope in a lunar crater, the Lunar Crater Radio Telescope, has received $500,000 for further study. Read more…

From Innovation News Network: NASA has created the Solar System Exploration Research Virtual Institute (SSERVI), bringing together teams of researchers who are interested in the Moon, asteroids and the moons of Mars, airless bodies in Earth’s neighborhood. Most of the teams involved in SSERVI are therefore interested in areas such as lunar geology, resource extraction, and so on. However, the Network for Exploration and Space Science (NESS), which is headed up by Dr Jack Burns at the �鶹��Ѱ��, proposed to do astrophysics and cosmology from the Moon, as the far side of the Moon, in particular, is the only truly radio quiet location in the inner Solar System. As such, the far side of the moon is the perfect place to locate radio telescopes that can be used to explore aspects of the Universe that cannot be addressed in any other way. These include, Burns told The Innovation Platform, the so-called ‘dark ages’ of the Universe, the cosmic dawn, and, indeed, exoplanets. “We can also use these telescopes on the far side of the moon to look at the Sun,” he said.

Led by the University of Colorado, NESS has developed into a team of ten universities and NASA centres which have been working together for almost four years. The network is actively involved in addressing some of the broad design questions for missions to the Moon. Burns explained: “We look at the science drivers, undertake theoretical modelling, conduct equipment and instrument design, and plan missions. We have been successful in doing that, and there are a couple of exciting missions coming up in the next few years, and then we will propose more for the longer term.” Read more…

From Astronomy.com: For radio astronomers, Earth is a noisy place. Many modern electronics leak radio signals, which interfere with the long, faint wavelengths of light studied by radio observatories. And for decades, this invisible light pollution has pushed radio observatories deeper into so-called “radio quiet zones.” This forces radio astronomers far from other people, out to places like the barren Atacama Desert in Chile.

But it’s not just human-made devices that obstruct faint radio signals. Natural phenomena from Earth and the Sun can interfere, too. Adding insult to injury, Earth’s ionosphere — where solar radiation ionizes molecules in our upper atmosphere — blocks the longest radio wavelengths from reaching our planet’s surface at all.

Scientists have long eyed a solution: the farside of the Moon. Because it always faces away from Earth, a radio telescope placed on the lunar farside would be almost completely sheltered from Earth-generated radio noise. There, astronomers would study a range of phenomena that can’t be seen from our planet, or even by Earth-orbiting space telescopes. A telescope on the Moon could show us what happened before the universe formed its first stars and galaxies, or let us see electromagnetic fields around distant exoplanets, revealing extremely subtle yet fundamental properties related to a world’s true potential for hosting life.

The Far Side Of The Moon Is The Perfect Place For a Radio Telescope

We’ve now passed the 50th anniversary of the Apollo 11 landing, and all eyes are back on the Moon. NASA is planning to return to the Moon by 2024 with its Artemis mission, the Chinese have put the Moon firmly in their plans for space exploration, and even SpaceX thinks the Moon is the perfect destination to test out the capabilities of its Starship.

But what can you do with the Moon? Refuel spacecraft with resources drawn from the lunar regolith? Mine its helium 3 for your fusion reactors? Build a lunar amusement park?

In fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earth’s constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe. Watch the video.
