NASA's Jet Propulsion Laboratory has a great video on how Entry, Descent and Landing will take place when the Phoenix Mars Lander reaches Mars on 25 May 2008.

NASA has released some interesting material on the composition of the Universe - as it is today and as it was 13.7 billion years ago, 1 second after the Big Bang. Dark Matter , which forms 23% of the Universe, is different from atoms and does not emit or absorb light. It has only been detected indirectly by its gravity. The bulk of the universe, 72%, is composed of " Dark Energy ", that acts as a sort of an anti-gravity. This energy, distinct from dark matter, is responsible for the present-day acceleration of the universal expansion. Atoms, the building blocks we are made of, comprise of just 4.6% of the Universe. It's amazing that atoms are so scarce in the Universe and even more amazing how irreverently we treat our Earth and fellow-beings.
