Stories, updates, insights, and original analysis from The Planetary Society.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.
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
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.
I saw this posted by @Akatsuki_JAXA (the Akatsuki Venus mission's official Twitter identity) and thought it was cute so I'm sharing it here.
I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).
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.
The Hayabusa update is brief: having opened the first Hayabusa sample return chamber (compartment A) last month, JAXA has now opened compartment B, and they found nothing inside.
An English-language article in the December 11 Yomiuri Shimbun summarizes the news from the Akatsuki press briefing held at 11:00 December 10 JST (last night, my time). It's succinct and clear so I'm reposting it here.
This image is so, so beautiful, and so, so sad.
I've got two more pieces of information to share on Akatsuki further to what I posted yesterday. The first one is a worrying detail about what went wrong during orbit insertion.
JAXA held two press briefings about Akatsuki yesterday. Reports in both English and Japanese based on these press briefings have cleared up some, but not all, of the mystery about what happened and what is to happen with Akatsuki.
There is a press briefing happening right now in Japan, and it's terrible news: Akatsuki failed to enter Venus orbit.
A press release (PDF) was posted in Japanese on the Akatsuki website this morning with some official information on the mission status. Here is a translation of the text.
I was unable to follow Akatsuki's entry into Venus orbit in real time due to family obligations. Checking in now, about four hours after it was to have entered orbit, it seems that something did not go correctly, but not much information is available.
In just a few hours, Venus will have a second orbiter. Japan's Akatsuki is due to start firing its orbit insertion engines on December 7.
