quote:A Japanese spacecraft touted to be the largest aimed at the moon since NASA's Apollo era rocketed into space late Thursday on an ambitious mission to study the origins of Earth's nearest neighbor.
The three-ton Kaguya lunar orbiter rode its H-2A rocket moonward at about 9:31 p.m. EDT (0131 Sept. 13 GMT), though it was Friday morning at Japan's island-based Tanegashima Space Center launch site. The probe was slated to circle the Earth twice before beginning a five-day trek to the moon, the Japan Aerospace Exploration Agency (JAXA) has said.
Formally known as SELENE, short for SELenological and ENgineering Explorer, Kaguya carries 14 science instruments and two small microsatellites to make detailed maps of the moon's surface, probe its interior and study the lunar gravitational field.

I was having a look at the website for the Kaguya spacecraft and was very pleased to see that it is carrying an HDTV camera. They mention explicitly that it can be used to film the Earthrise.
I honestly haven't heard much about this probe but I have a feeling that when the first HDTV images of Earthrise from lunar orbit are relayed back from this satellite they are going to become some of the most famous images in recent space history.
Seeing modern HD images of the moon from orbit is going to be amazing, and you can sure they're going to be shown on every news broadcast in the world.

The JAXA spacecraft has now entered lunar orbit, and sent back the first images. Although the images are not spectacular, they were just taken to monitor the antenna.

Here is a one minute video of Earth taken with Kayuga's HDTV camera while it traveled to the Moon. The online version is not full resolution of course but neat nonetheless.

Just noticed that a new video was posted on Oct 30. It starts with about 25 seconds of Japanese text but then shows two fairly long shots of the lunar landscape passing underneath the spacecraft. Takes you back 30+ years!
See the clip here. It's the top one that shows just text (V-044-0017). Sadly it's not in HD.

In the image, the Moon's surface is near the South Pole, and we can see the Australian Continent (center left) and the Asian Continent (lower right) on the Earth. (In this image, the upper side of the Earth is the Southern Hemisphere, thus the Australian Continent looks upside-down.)

OMG. When I first saw your post here Robert I assumed it was a Photoshop creation by a cSer. But it is real. Amazing. Beautiful.

In space I guess you can fly in attitude you want so there's no particular reason why the camera/viewer should be feet down when passing over the North pole and head down when passing 'under' the South pole.
I assume 'down' there in Sydney you wouldn't stand on your heads to a polar-orbiting satellite pass over the 'right way up'.

Hey guys -
I just noticed something. This is obviously a poor fake - where are the stars in the sky? Talk about mediocrity - they have made the same mistake that we made three decades ago! When are we all going to get our respective acts together on faking lunar missions?

I'd be surprised if the cameras have a powerful-enough combination of lenses and resolution to see anything significant at the landing sites but I could be wrong.
In any case I'm sure they will release high-def stills of those area once the probe has passed over them. Still be interesting to see Hadley Rille and the like.

I have a question (or perhaps an observation) as to HD resolution vs. the old Apollo Hasselblad images. According to the JAXA web site, the Kaguya imager is 1920 x 1080, which would make sense since that's the resolution of full HDTV. So, that's around 2 megapixels. By contrast, the resolution of a Hasselblad image exceeds 30 mp. So, even though the Kaguya images appear spectacular, it would seem that their resolution is still far, far less than the 40-year-old pictures from Apollo (although color accuracy is probably higher). Any thoughts? Dave

The high-definition digital images are of course way lower in resolution than Hasselblad stills from the Apollo missions but the comparison should really be with the movie cameras used in orbit.
Maybe Mark of Spacecraft Films could chip-in with his opinion?

Even more amazing is the fact that these images are coming from a Japanese spacecraft. If in Europe or US, the spaceflight program won't get the attention/funds it needs in the future, the Moon might become an Asian affaire...

Both Apollo 15 + 16 landing sites are listed (Word document) as lunar sites to be used in calibrating the Japanese spacecraft instruments!

Just watched the video for the first time, like someone has already mentioned it's just like being there. That view is breath taking.

No Paul, but we might get images of the Apollo 15 + 16 landing sites. In 50 years spaceflight, the best images were those taken by Viking on Mars and when we saw those Viking spacecraft from orbit, that was really cool! Hopefully same deal for Apollo
