Here's a composite of the 3 first light images. Love that, really beautiful picture. -------------------- |

I'm reading elsewhere that radio contact has been lost with 3 of the 4 minisats...only Negai☆ is operating normally. That's unfortunate to hear.

IKAROS Update:
-IKAROS is 2,266,103 miles (3,646,160 km) from Earth as of today -the spacecraft is currently spinning at 20 rpm...will increase to 25 rpm by tomorrow before the solar sail finally begins full deployment this week http://www.isas.jaxa.jp/home/IKAROS-blog/ -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

New images taken by IKAROS...showing the four tip masses that are on each outer tip of the solar sail have successfully separated from the spacecraft
http://www.jspec.jaxa.jp/ikaros_channel/bn004.html As an FYI, three of those four tip masses contain many aluminum plates engraved with the names of 63,248 people. These names were submitted online as part of a public outreach effort by JAXA between December 2009 and March 22 of this year. -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

punkboi, it looks like we posted the same link in two separate topics

This is interesting: studies have been carried out on the possibility of sending Akatsuki's secondary payloads to other targets in the solar system. It turns out Apophis can be reached

I would assume that the secondary payload they're referring to is IKAROS; three of the four minisats are stuck in Earth orbit...and I don't think UNITEC-1 has any onboard propellant that would allow it to change course once it reached Venus.

If I understand correctly this JAXA release (in Japanese only) Akatsuki carried out its first 12m/s course correction on 28 June

JAXA has released some stellar calibration images taken earlier this month
http://www.stp.isas.jaxa.jp/venus/index.html unfortunately, the release is in Japanese only, but the google translation is quite readable |

two interesting-looking pages on Akatsuki telecommunications systems and antennae
http://www.nec.co.jp/ad/cosmos/akatsuki/02/?cid=twi http://www.isas.jaxa.jp/j/column/akatsuki/06.shtml unfortunately, they are only in Japanese for the time being... |

Date of AKATSUKI injection to Venus orbit
http://www.jaxa.jp/countdown/f17/index_e.html JAXA decided to emit jets from the orbital maneuvering engine (OME) of the AKATSUKI at 8:49:00 a.m. on Dec. 7 (Japan Standard Time, all the following dates and time are in JST) to inject the orbiter into the Venus orbit. Under the current schedule, the OME jet emission will be completed at 9:01:00 a.m. on the same day, and the Venus orbit will be determined around 9:00 p.m. also on the same day after some attitude control maneuvers including the Earth pointing maneuver of the Z axis. The AKATSUKI will study the Venus atmosphere for about two years after being injected into the Venus orbit 8:49:00 a.m. on Dec. 7 JST (11:49:00 p.m. on Dec. 6 UTC) **** What I'm wondering is when Akatsuki will start taking images of Venus as the spacecraft nears arrival...and when JAXA will release 'em -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

What I'm wondering is when Akatsuki will start taking images of Venus as the spacecraft nears arrival...and when JAXA will release 'em I don't know the details of science operations : the JAXA team is understandably focussed on getting safely into orbit first. NASA did just announce (although oddly not yet linked on the NASA or JAXA Akatsuki pages, as far as I can tell) the selection of US-supported participating scientists for Akatsuki. Among their (our) tasks will be to assist with archiving the data in a PDS-consistent format and with Education/Public Outreach efforts.... http://www.jpl.nasa.gov/news/news.cfm?release=2010-389 |

from the latest ESA bulletin (published online yesterday http://www.esa.int/esaCP/SEMO6LIRPGG_index_0.html )
QUOTE The Japanese Venus Climate Orbiter, Akatsuki, was launched on 21 May. It is due to arrive in orbit around Venus on 7 December. Joint operations between Akatsuki
and Venus Express will start in January 2011 and will cover a large number of different cases, including simultaneous observations at different scales, differential radio science observations, long-term chained tracking of cloud patterns, spectral versus large-scale imaging observations and cross-calibration. Several of these observations will also be coordinated with observers at a number of the world’s leading ground-based observing facilities. |
