Japan's Venus climate orbiter Akatsuki failed to enter orbit in December 2010 when a clogged valve caused catastrophic damage to its main engine. Since then, JAXA's engineers and navigators have determined that although the main engine is a total loss, there is the possibility of achieving Venus orbit on a future encounter, using only the attitude control rockets.
JAXA held a press conference on June 30 about the latest report from the review board that is charged with finding out what exactly caused Akatsuki's failure to enter orbit at Venus, and what that implies for the possibility of Akatsuki to try again when it returns to Venus in 2015 or 2016.
Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.
April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.
There are two intriguing possibilities being discussed in the Japanese media for what to do with Akatsuki, a space probe in orbit near Venus with a fully functional, highly capable suite of cameras but a damaged main engine.
In a move that's kind of hard to understand in the wake of the immense public outreach success of the Hayabusa mission, JAXA is closing JAXA i, its public information center in Tokyo today (December 28 in Japan).
Ordinarily it's not my thing to do so many updates on a mission that failed to arrive in orbit, but I know that it's difficult for English-speaking readers to locate information on Asian missions so I'm keeping up the reporting on Akatsuki.
