(ORDO NEWS) — Astronomers have not yet been able to study a significant part of the radio emission from our universe due to the interference that the Earth creates.
Scientists hope to change this over time. And they plan to start with the launch of the LuSEE mission to the far side of the moon.
LuSEE will be launched in 2025. It should be the first step towards the creation of lunar observatories.
The earth sounds loud on the radio, especially at frequencies below 20 megahertz. The planet’s ionosphere crackles at these frequencies, drowning out radio emissions from more distant sources.
In addition, we use low-frequency radio waves for communication and radar searches, jamming space sources.
The best way to avoid this terrestrial “pollution” is to go to the far side of the moon. The lunar body will block radio emission from the Earth. The sun is also a fairly loud emitter of radio signals at these frequencies.
For this reason, observations can be made during the lunar night, when the far side of the Moon is immersed in darkness.
Building radio observatories on the Moon is a labor-intensive task. One of the first steps towards this is LuSEE, an electromagnetic explorer of the lunar surface.
LuSEE is an almost identical replica of one of the instruments aboard the Parker probe. The device consists of two cross-mounted 6-meter antennas and a set of electronics.
The device operates relatively silently. It will not increase radio pollution. LuSEE will be able to send data to an orbiting lunar spacecraft, which will relay it back to Earth.
Astronomers hope that the mission will be successful, and in the future there will be observatories on the far side of the moon that can help in space exploration.
