Hayabusa Captured its Home Earth!

Hayabusa successfully photographed its home Earth and Moon on May 12th last week, by using the CCD sensor on the Star Tracker instrument aboard.

The Earth was seen so brightly that the image contained strong smear in it, but the image clearly separates the Moon from the Earth. (Magnitude of the Earth is -8.3, and that of Moon is -4.6.)

The Earth was seen between Sagittarius and Capricornus.
Hayabusa will continue to voyage back to Earth at the speed of 18 thousand kilometer per hour.

Nail biting time ahead,,,capsule separation and parachute deploy. ( Looks like TCM4 is optional/fine trim  within the WPA )

Any idea about the ETA?- could not find it from the JAXA site, though it says TCM3 is around 7days ahead of reentry.

1400 UTC on June 13th according to the presser from April and per post one page up:
http://www.jaxa.jp/press/2010/04/20100421_hayabusa_e.html

Some details about the planned entry flight path angle, speed, expected g-loads or the like would be cool ...?

Hayabusa is due to return on Sunday to Australia. Does anyone know its ground track be as it heads towards central Australia. If it comes in over the Indian Ocean could it be seen from Perth WA ?

There was some chatter on Twitter that it would be difficult to observe. Note the landing time is about 11:30pm local so it will be coming in the dark.

Apparently there will be at least an attempt to get live video at the site below:

I'll be watching with bated breath! Go Hayabusa! :D

This is why I love space exploration (manned, womanned, or unmanned):
The most important missions are always those on the bleeding edge of the possible, in spite of every attempt to make everything as flawless as possible. Just amazing.

Go JAXA!
