JAXA wants to continue with Hayabusa 2. However there is/was a huge fight about the budget. Main problem was the budget for the launch vehicle. 2 months ago or so there was a report which said, that JAXA had to find another launch vehicle or the project gets cancelled. Now the Italian space agency played saviour and overed the VEGA. So finally we might see another Hayabusa in 2011.

Occultation by asteroid 2001 CC21 has been observed
https://www.hayabusa2.jaxa.jp/topics/202303...CC21/index.html https://www.hayabusa2.jaxa.jp/topics/20230314_2001_CC21/ [only in Japanese - here's a rough automatic translation of the excerpts]: “… An occultation (stellar eclipse), in which (…) asteroid 2001 CC21 hides a star, was observed during an occultation observation campaign conducted (…) on March 5, 2023. During the observation we monitored the light of a 10.1-magnitude star in Camellia (TYC4082-00763-1) to see if the light from this star faded. Observations were made from 20 points (…) However, the occultation was observed only in one place. The time during which the star was hidden (occultation time) was 0.105 seconds. This is 449 m ± 12 m in length. (…) The size of CC21 is estimated to be about 700 m (…), is said to have a slightly elongated shape, and the short part [of the atseroid] may have been measured in this observation. We also examined the orbital accuracy of CC21 as of July 2026, when Hayabusa2 spacecraft will fly by, and found that the positional error of CC21 is 47 km (1σ). There are still opportunities for occultation observations by CC21, so we hope to observe a stellar eclipse in the next observation (…). It may also be possible to determine the shape of the asteroid by conducting more accurate occultation observations in the future…” |
