China`s 1st interplanetary probe hits mars mission
Loss of China’s first interplanetary probe, attached to an ill-fated Russian spacecraft, has cost scientists the chance to conduct breakthrough research on Mars.
New Delhi: The loss of China’s first interplanetary probe, attached to an ill-fated Russian spacecraft, has cost scientists the chance to conduct breakthrough research on Mars, according to a top scientist.
Wu Ji, director-general of the National Space Science Center under the Chinese Academy of Sciences, sad that new objectives must now be considered for a Mars exploration mission, probably in 2016.
Yinghuo-1, launched in November two years later than was originally planned from Kazakhstan on a Russian spacecraft, crashed into the Pacific Ocean on Monday.
The Russian Phobos-Grunt spacecraft the probe hitchhiked on failed to fire two booster engines that would have set it on course for the Red Planet.
However, no reason was given for the failure of the booster engines.
Wu said that the failure cost the centre a chance to conduct research and come up with breakthrough findings before their counterparts in the United States.
“We had hoped that the micro-satellite could help us discover something about the atmosphere on Mars,” the China Daily quoted Ji as saying.
He also said that the US will send a probe to Mars in 2013.
As China’s first probe to Mars, the Yinghuo-1 mission had been expected to explore the Red Planet’s environment, climate history and look into why water had vanished from the surface.
Those specific objectives were selected by the centre in 2006 to differentiate China’s mission from those of other countries.
“Previous missions mainly focused on whether there is water and life on the planet, consequently humans have limited knowledge of the Martian atmosphere,” Ji said.
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, scheduled to launch in 2013, also aims to find about the Red Planet’s atmosphere and climate history, among other tasks.
The MAVEN mission was selected in 2008 from 20 proposals submitted in response to a NASA Announcement of Opportunity in 2006.
Both countries are interested in the Martian atmosphere as it continues to be a cause of intrigue for scientists.
Mars once had a denser atmosphere that supported the presence of water on the surface but it suddenly changed and scientists are unsure as to what exactly was behind it.
Wu said that with Yinghuo-1’s failure, China has to wait until 2016, at the earliest, to launch a Mars probe.
“This means that the US MAVEN mission will get there before we do, and therefore we have to change our goals for the next Mars exploration mission to avoid findings being repeated,” Ji added.
