| | | | | | | Close encounters with Mars
25 August 2003
| About the same time as Earth and Mars make their
closest approach in more than 60 000 years, ESA's Mars Express
passes the halfway mark of its journey, as regards distance.

| Taking advantage of Mars's closest approach to Earth in eight years, astronomers using NASA/ESA Hubble Space Telescope took the then sharpest views of the Red Planet in 1999. The telescope's Wide Field and Planetary Camera 2 snapped this image Mars when it was only 87 million kilometres from Earth. From this distance the telescope could see features as small as 19 kilometres wide. If you were travelling with Mars Express, this is the view you might have a few days before arrival at a distance of several thousand kilometres.
This image is centred on the dark feature known as Syrtis Major, first seen by the astronomer Christian Huygens in the 17th century. Clearly visible are the icy north and south poles, and along the right limb, late afternoon clouds have formed around the volcano Elysium.
Quote: Five days before entering final orbit, Mars Express will be on a collision course with the planet.
