Japan probe shoots past Venus
Baku, December 8 (AZERTAC). A Japanese space probe has hurtled past Venus after failing to enter the planet's orbit as planned, the space agency said Wednesday, but it voiced hope for a successful rendezvous six years from now.
The "Akatsuki", or "Dawn", blasted off in May on a 300-million-dollar mission to observe the toxic atmosphere and super-hot volcanic surface of Venus, which is sometimes called the Earth`s sister planet.
However, in a setback for Japan's space program, the box-shaped golden probe failed to enter the planet`s gravitational pull and shot past it, said the Japan Aerospace Exploration Agency (JAXA).
"It will come close to Venus again in roughly six years, giving us another opportunity," said JAXA spokesman Hitoshi Soeno, who stressed that ground control in Sagamihara near Tokyo, was still in command of the probe.
Masato Nakamura, the chief developer of Akatsuki, said a second attempt was "highly doable", according to the Jiji Press news agency.
The Akatsuki, also called the Planet-C Venus Climate Orbiter, was sent on a mission to orbit and observe Venus for two years, working closely with the European Space Agency`s Venus Express.
It is fitted with two paddle-shaped solar panels and five cameras to let it peer through the planet's thick layer of sulphuric acid clouds, and was also due to search for signs of lightning and for active volcanoes.
Venus is similar in size and age to Earth but has a far more hostile climate, scorching at around 460 degrees Celsius (860 degrees Fahrenheit) and with large amounts of carbon dioxide, the primary greenhouse gas on Earth.
Scientists believe that investigating the climate of Venus would deepen their understanding of the formation of the Earth's environment and its future.
The Japanese probe on Tuesday morning Japan time reversed its engine thrust to slow down and enter the gravitational field of Venus, said JAXA, which had Tuesday reported communication problems with the probe.
On Wednesday JAXA announced that its mission had failed.
"We started the maneuver to put the Venus probe Akatsuki into orbit around Venus at 8:49 am (Tokyo time) on December 7... but have confirmed that we could not put it into the orbit," it said in a statement.
The exact cause of the failure was not officially determined yet but one possible explanation was that the probe did not slow down enough near Venus to be pulled in by the planet`s gravity, Soeno said.
Japan's top government spokesman Yoshito Sengoku said "it was very regrettable that the probe did not succeed in entering the orbit around Venus. We'd like to continue watching Akatsuki`s situation."
