PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Telescope reflector. Cutaway computer artwork of a telescope with a Maksutov Cassegrain reflector. The red arrows represent beams of light that pass through the telescope's meniscus lens (blue, top) and are reflected to the eyepiece (bottom) using concave (lower centre, white) and convex (upper centre, also white) mirrors.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Annular solar eclipse, computer artwork. Solar eclipses occur when the Moon passes across the Sun as seen from the Earth. The Moon's shadow consists of a dark central umbra surrounded by the lighter penumbra. Annular solar eclipses occur when a region on the Earth's surface is in line with the umbra, but the tip of the umbra does not reach the Earth's surface. This is because the Moon's orbit is elliptical and varies in its distance from the Earth. On average, the Moon is far enough away to appear smaller than the Sun, resulting in an annular eclipse. It is only when the Moon is closer than average that a total eclipse occurs.

The LRO was launched on 18th June 2009 and entered lunar orbit on 23rd June 2009. It will stay in lunar orbit for at least one Earth year, mapping the surface, surveying resources and identifying possible landing sites for manned missions.

Computer artwork of the Orion crew module (lower right) docking to the Altair lunar lander, which is still attached to the Earth departure stage of the rocket launcher Ares V. These spacecrafts are part of NASA's Constellation Program, a US space program that was announced in 2004. The program is intended to launch in around 2014 and its mission is to put astronauts back on the Moon by 2020.
