APOD: Yutu Rover Rolls onto the Moon (2013 Dec 16)

Post by APOD Robot » Mon Dec 16, 2013 5:06 am

Image Yutu Rover Rolls onto the Moon

Explanation: A new desk-sized rover has begun exploring the Moon. Launched two weeks ago by the Chinese National Space Administration, the Chang'e 3 spacecraft landed on the Moon yesterday and deployed the robotic rover. Yutu, named for a folklore lunar Jade Rabbit, has a scheduled three-month mission to explore several kilometers inside the Sinus Iridum (Latin for "Bay of Rainbows") impact crater. Yutu's cameras and spectrometers will investigate surface features and composition while ground penetrating radar will investigate deep soil structure. Chang'e 3 achieved the first soft Moon landing since the Soviet Union's Luna 24 in 1976, and Yutu is the first lunar rover deployed since the USSR's Lunokhod 2 in 1973. Pictured above, Yutu was imaged from its lander yesterday soon after rolling onto the Moon.

Gee, the scenery looks like the same background from Apollo....

Could the Apollo truthers be wrong?

The somewhat clearer photo in the second last link in the caption (namely "imaged") ... http://news.xinhuanet.com/english/china ... 970111.htm

appears to show that the lander is very close to a steep looking slope and depression. Could it be that the programmer(s) engaged to write the algorithm to select the best landing site in real time, perhaps got a bit lucky?

Congratulations to the Chinese. Anytime any country reaches a spaceflight and exploration milestone such as this one, I celebrate. These achievements are for all of us, not any one nation, in the end.

I hope we'll be getting better imaging soon.

I also hope that China is working up to joining the other nations that have been cooperating to advance spaceflight and exploration. Their contribution would surely help humanity progress.

I suppose when impressive space exploration achievements are made, it is easier for citizens of non-space-faring nations, like mine, to celebrate humanity over nationality and avoid the "us and them" mental framework. I like to imagine the dolphins of the world are also quietly enjoying an extra pilchard or two this week, as news filters down to them about the exploits of Chang'e 3 and Yutu. (The chimps are probably happy to have been left alone for this mission, too.)

Congratulations to all involved.

Yes, all politics aside, I'm glad to see that there is a rover on the moon. I just wish that we (i.e., our country) could have participated.

Now it's 2 "outs" for us ~~ the ISS transportation and more moon exploration. Come on folks, let's get going!!!

And if you look to the right of the rovers track, it is clear that the set designers didn't do a very good job of obscuring their footprints either. :lol2:

Is that, actually, the curvature of the Moon or a result of a wide-angle lens?

Some combination of the optics and the local landscape. The Moon is far too large to show any curvature for an observer at the surface.

In the case of a goofy grinning avatar, the challenge is to figure out when the individual is being serious.

This is the 1st landing on the Moon since 1976 (Luna-24).
Quite a shame really that it took so long to go back.

According to the wikipedia article on the International Space Station Program, an intergovernmental agreement among NASA (USA), Roskosmos (Russia), ESA (European Union), JAXA (Japan), and CSA (Canada), China has expressed interest in joining the International Space Station but the US has objected.

It seems that space programs at first are a source of national pride, then they become commercial enterprises. Hopefully we'll get to the point where all humanity is collaborating on space exploration. It may take a while longer to figure out joint missions with the dolphins.
May all beings be happy, peaceful, and free.

What is all that on the ground which appears to be debris ,trash, or something else ??

Can anyone check the route of the photo's transmission once it landed on earth? Seems like someone blurred the photo to make Chinese technology look bad.

It looks kinda like the result of a video camera filming a projection onto a screen, or something like that. I recall (vaguely from some documentary) that a similar thing happened with the live images broadcast of the Apollo 11 landing. Possibly a last minute technical glitch or some overlooked technical incompatibility.

The area where this spacecraft landed, Sinus Iridum, is an ancient lava flow.

Image

Over billions of years the lava has deteriorated into fine dust -- without liquid water or an atmosphere, erosion happens much more slowly on the Moon than here on Earth, but charged particles and radiation from the Sun will eventually break down rock. We can see a small crater in the upper right hand corner of today's picture. The impacts of asteroids and meteoroids that caused this and other craters kicked up rocks that fell back to the surface of the Moon at varying distances from the original impacts. So I would guess that most of the debris we see in this photo are ejecta from crater impacts.

Or they could be hamburger wrappers carelessly dropped by the stagehands who built the set on which this scene was filmed.
:lol2: Only kidding. Chang'E 3 and Yutu really landed on the Moon. Don't believe anyone who tries to tell you otherwise.
May all beings be happy, peaceful, and free.

Interesting ... I just noticed that Wikipedia now says this:

http://en.wikipedia.org/wiki/Chang'e_3
Topographic data from the Chang'e 1 and 2 orbiters were used to select a landing site for Chang'e 3. The planned landing site was announced to be Sinus Iridium [sic], however, the lander descended on Mare Imbrium, about 40 km south of the 6 km diameter Laplace F crater, at 44.1260°N 19.5014°W on 14 December 2013.
(This puts the landing site about midway between Montes Recti and the 20km diameter crater Le Verrier.)
