ESA INFO 11-2003 ESA sets ambitious goals for the first European mission to Mars
On 2 June 2003, the first European mission to Mars will be launched. It will also be the first European mission to any planet. Mars Express has been designed to perform the most thorough exploration ever of the Red Planet. It has the ambitious aim of not only searching for water, but also understanding the 'behaviour' of the planet as a whole. However, the most ambitious aim of all may be that Mars Express is the only mission in more than 25 years that is daring to search for life.

Looking for life of any shape or form
On 25 April 25 1953, James D. Watson and Francis H. Crick published an historic paper in Nature that would change the fate of modern science. They proposed that DNA, the molecule of complex life forms, had the shape of a double helix. Today, scientists from all areas are working together to answer the ultimate question: can life (in any shape or form) exist anywhere else in the Universe?

Mercury shows its dark side
During the morning of 7 May 2003, the planet Mercury will slip across the face of the Sun in a rare event, known as a transit. There are only about 12 celestial alignments like this every century and you cannot view them safely without special telescopic equipment. So, let the ESA/NASA solar watchdog, SOHO, do all the hard work for you...

Finding the ashes of the first stars [heic0306]
Recent observations with the Hubble Space Telescope suggest that the first stars formed as little as 200 million years after the Big Bang. This is much earlier than previously thought. Astronomers have observed large amounts of iron in the ultraluminous light from very distant, ancient quasars. This iron is the 'ashes' left from supernova explosions in the very first generation of stars.

How constant is our changeable Universe?
Constants govern the way our Universe behaves. We regard them as fixed, unchanging quantities. However, how can we be sure that constant really means constant? Modern theories require the values of universal constants to slowly change during the course of cosmic history. Is this the case? ESA is preparing to search for (small) changes in the 'constants of nature'.

How far can a dentist's drill go?
When ESA's Mars Express reaches the Red Planet in December 2003, there will be a drill on board its Beagle 2 lander. This drill will dig into the surface to take samples of the Martian rocks. Who would imagine that the creativity of an enthusiastic dentist is behind a 'cosmic' drill?

Splashing down on Titan's oceans
Titan, Saturn's largest moon, is a mysterious place. Its thick atmosphere is rich in organic compounds. Some of them would be signs of life if they were on our planet. How do they form on Titan? Will they help us to discover how life began on Earth?

Hubble watches light echo from mysterious erupting star [heic0304]
In January 2002, a moderately dim star in the constellation Monoceros, the Unicorn, suddenly became 600 000 times more luminous than our Sun. This made it temporarily the brightest star in our Milky Way. The light from this eruption created a unique phenomenon known as a 'light echo' when it reflected off dust shells around the star.

First evaporating planet excites European astronomers
Using the Hubble Space Telescope, for the first time, astronomers have observed the atmosphere of an extrasolar planet boiling off into space. Much of this planet may eventually disappear, leaving only a dense core. The planet is an example of a type of exoplanet known as a 'hot Jupiter'. These giant, gaseous planets orbit their stars very closely, drawn to them like moths to a flame.
