In a few
years, a tiny radio telescope on the far side of the moon might enable
researchers to look back in time to the beginning of the cosmos.
The Lunar
Surface Electromagnetics Experiment-Night (LuSEE-Night) is a moon instrument
that is being developed by NASA's Science Mission Directorate, the University
of California, Berkeley's Space Science Laboratory, and the Brookhaven and
Lawrence Berkeley National Laboratories of the United States Department of
Energy.
Currently,
LuSEE-flight Night's on a personal robotic lunar lander is planned for late
2025. It will make an effort to collect first-of-their-kind measurements
from the "Dark Ages" of the cosmos after touching down on the far
side of the moon.
In the early
universe, between roughly 400,000 and 400 million years after the Big Bang,
before stars and galaxies started to completely form, there was a period known
as the Dark Ages. In order to find what researchers are calling the Dark Ages
Signal, LuSEE-Night will detect faint radio waves from the Dark Ages from the
far side of the moon using onboard antennas, radio receivers, and a
spectrometer.
"Until
now, we have only been able to guess the early universe using a standard identified
as the cosmic microwave background. A new standard would be provided by The
Dark Ages Signal, "Ane Slosar, a physicist at Brookhaven, said in a
statement . Additionally, if forecasts based on each benchmark don't line up,
new physics has been found.
LuSEE- Since
night is a pathfinder intended to open the way for more ambitious instruments
in the future, it is not necessary expected to make such significant
advancements on its own. According to team members, the broader project may end
up providing answers to important cosmic mysteries like the nature of dark
energy and the origin of the universe.
Because it
offers something Earth cannot: a profound and deep silence, the far side of the
moon is a great location to search for the faint signals that could contain
such clues. The environment on our world is too noisy for the supersensitive
instruments LuSEE-Night will use because of constant radio bombardment.
However, the remote location also poses difficulties.
There,
surviving requires a technical miracle. The portion of the moon that faces away
from us in the night sky, which is occasionally incorrectly referred to as
"the dark side," does, in fact, have a day/night cycle, with each
period lasting about 14 Earth days. On the far side of the moon, temperatures
range from about 250 to negative 280 degrees Fahrenheit (121 and minus 173
degrees Celsius).
Therefore,
LuSEE-Night will need to be built to endure two weeks of relentlessly
unforgiving lunar-day sun in addition to remaining powered through two weeks of
rigidly cold night — and do this repeatedly. Two years is the intended mission
duration on the lunar surface
In the same
statement, Joel Kearns, deputy associate administrator for exploration in
NASA's Science Mission Directorate, said: "LusEE-Night lunar night
survival technology demonstration is essential to conducting long-term,
high-priority science investigations from the lunar surface.
