Snimka mjeseca

Japanci na internetu objavili snimke Mjeseca
Za sve one koji su se pitali kako izgleda krajolik Mjeseca viđen iz njegove orbite, japanski znanstveni tim donio je odgovor. S japanske svemirske letjelice Kaguya nedavno su odaslana dva videoisječka što prikazuju površinu Mjeseca

apanci su Kaguyu lansirali u svemir 14. rujna ove godine, a njen je prvi i osnovni zadatak prikupljanje što većeg broja podataka o Zemljinom najbližem susjedu. Misija, između ostalog, uključuje studiju o porijeklu Mjeseca i njegovoj geološkoj evoluciji te daje informacije o izgledu i karakteristikama njegove površine, a trebala bi trajati oko godinu dana.

Kako je jedan od njenih glavnih ciljeva proučavanje površine Mjeseca, letjelica je opremljena high definition videokamerom koja je snima s udaljenosti od stotinjak kilometara. Dio snimljenog materijala sada se može pogledati i na internetu.

U prvom videoisječku kamera je usmjerena prema dolje - dok se letjelica približava Mjesečevom sjevernom polu - a drugi isječak prikazuje dio Mjesečeve sjeverne hemisfere, zapadno od tamne ravni poznate kao Oceanus procellarum (Ocean oluja).

Snimka je nastala 31. listopada, a japanska svemirska agencija JAXA odlučila je pomoću interneta pokazati video širokoj javnosti.

Ajme... uvijek sam željela to vidjeti. I nikad me neće proći želja da odem tamo.
Posebno mi se sviđa zadnja četvrtina snimke (the dark side of the moon) jer se jasno vide obrisi udarnih kratera.

North Pole Area (still image cut out from the first image shooting)
This is a still image taken out from the first moving image shooting when the KAGUYA flew from the northern area of the "Oceanus Procellarum"(*1) to the center of the North Pole.
As the altitude near the North Pole is high, the angle of the coming sunlight was lower, thus the shade of the crater topography looks long in the image.
The moving image was taken at 4:07 a.m. on October 31, 2007 (JST) by eight-fold speed intermittent shooting (eight minutes is converged to one minute) from the KAGUYA, and the data was received at the JAXA Usuda Deep Space Center on the same day.

(*1) Oceanus Procellarum:
The dark area on the Moon's surface called "ocean." It is located at the left end of the northern hemisphere on the front side of the Moon when we look up at it from the Earth.



(2) The western side of the "Oceanus Procellarum" (cut out from the second image shooting)
This is a still image taken out from the second moving image shooting when the KAGUYA flew from the south to the north on the western side of the "Oceanus Procellarum."
The dark part on the right of the above image is the Ocean (Oceanus Procellarum,) and the light area on the left is called the "highland."
The moving image was taken at 5:51 a.m. on Oct. 31, 2007 (JST) by eight-fold speed intermittent shooting (eight minutes is converged to one minute) from the KAGUYA, and the data was received at the JAXA Usuda Deep Space Center on the same day.


(3) The west side of the "Oceanus Procellarum" (cut out from the second image shooting)
This is a still image taken out from the end part of the second moving image taking.
We can observe a crater called "Repsold," whose diameter is 107 km, at the center on the near side of this image. The channel that crosses this crater is called the "Repsold Valley," and its length is about 180 km (equivalent to the distance between Tokyo and Shizuoka on the Tokaido Line in Japan.) The shooting time was the same as the above (2.)
