Kaguya, the famous Japanese Moon probe, is orbiting the Moon
since October 18 and so far is doing an amazing job.
According to JAXA, Japan Aerospace Exploration Agency,
Kaguya successfully shot high-definition images of the Earth-rise showing an
impressive image of the blue Earth which was the only floating object in
pitch-dark space.
Earth-rise is a phenomenon seen only from satellites that
travel around the Moon, such as the Kaguya and the Apollo space ship. The
Earth-rise cannot be observed by a person who is on the Moon as they can always
see the Earth at the same position.
The Apollo project was the first mission to take images of
Earth rising over the Moon. Two satellites carried by Kaguya, including one that will
eventually land on the moon, have already been launched into lunar orbit to
help the lunar mapping project.
Kaguya has taken these pictures thanks to the equipment provided
by the Japan Broadcasting Corporation (NHK).
The amazing images that the Japanese lunar probe took are to
be broadcast in high definition during “Return to the Moon: The First Images”,
a 30-minute special set to air on Discovery HD.
In one of the pictures, dubbed “Earth-set”, our planet
appears upside-down. So, one could see Earth’s Asian and Australian continents,
but they are hard to recognize, as they are practically upside-down from the
way we are used to seeing them on the map.
In another image the Moon's surface is near the North Pole,
and the Arabian Peninsula and Indian Ocean can
be observed on the Earth.
The images are available on JAXA website.
Kaguya was launched in September 14, 2007, and it represents
the second Japanese lunar orbiter spacecraft.
The $272-million Kaguya project is the largest lunar mission
- and the most sophisticated lunar exploration mission - since the Apollo
program. Kaguya’s satellites will carry out 14 missions, including measuring
the moon's gravity and determining its origin and evolution.
The results are expected to lead to a better overall
understanding of the Moon’s evolution. At the same time, the observation
equipment installed on the orbiting satellite will observe plasma, the
electromagnetic field and high-energy particles. The data obtained in this way
will be of great scientific importance for exploring the possibility of using
the moon for human endeavors.
