New 'Earthrise' Image from NASA: PHOTO

Earthrise

NASA's Lunar Reconnaissance Orbiter Camera released a stunning new shot of the Earthrise yesterday. In the photo, the Earth is a color composite very close to what a person would see from the same perspective, and the brightness contrast of the Earth and moon is also very accurate.

They write:

LRO experiences twelve earthrises every day, however LROC is almost always busy imaging the lunar surface so only rarely does an opportunity arise such that LROC can capture a view of the Earth. On the first of February of this year LRO pitched forward while approaching the north pole allowing the LROC WAC to capture the Earth rising above Rozhdestvenskiy crater (180-km diameter).

The LROC Wide Angle Camera (WAC) is very different than most digital cameras. Typically resolution is reported as the number pixels in a single image, a cell phone camera today has more than 5 million pixels (5 megapixels). A single WAC frame has only 9856 pixels, however the WAC builds up a much larger image by exposing a series of images (or frames) as LRO progresses in its orbit; this type of imaging is called "push-frame". Over a full month as the LRO orbit track progresses around the Moon the WAC builds up a collection of images that covers the entire globe.

  1. Hogwash - it's a composite not a photo.

  3. I can see my house from here!

    @disgusted merican - An exposure able to record the lunar surface and the Earth in sharp detail is nowhere near long enough to record starlight.

  8. Is it really earth "rise" if it's not taken from the moon's surface?

  9. Hey Little One,

    Sorry that everything in life is not as easy and simple as "just point and click". I ONLY have respects for the people who work in the "astrophograhy" field etc.
