FRIDAY 12 JANUARY, 2001 at the GEOLOGICAL SOCIETY,  BURLINGTON HOUSE, LONDON W1.

The mysterious planet Mercury will be the subject of this week's Open Discussion Meeting organised by the Royal Astronomical Society.

 

Leading space scientists from the UK, Europe and the United States will summarise our current, limited knowledge of the innermost planet in the Solar System and look forward to future missions and instrument packages - in particular the ambitious European Space Agency - Japanese Institute of Space and Aeronautical Science mission known as Bepi Colombo.

Media representatives are welcome to attend. Requests for interviews may be made by contacting the RAS Press Officer, Peter Bond (see contact details above).

Most speakers are expected to be available for interview during the lunch break, immediately after the meeting, or by prior arrangement. (On the day of the meeting, please use Peter Bond's mobile phone number, 07711-213486).

MYSTERIOUS MERCURY 

Although it is one of the closest planets to the Earth, Mercury remains an enigma, the terrestrial planet about which we know least. This is partly because it is hard to observe, since it is always close to the Sun in the sky, and partly because it is very small - not much larger than our Moon.

Most of our current knowledge is based upon information returned by the Mariner 10 spacecraft in 1974-5. During three flybys of the planet, Mariner 10 imaged about 40% of Mercury's surface. Little is known about the unseen far side, although radar observations suggest the presence of giant impact craters and the possibility of water ice inside permanently shaded, polar craters.

Much of what we do know is paradoxical and challenges our understanding of planetary formation and evolution. Why is Mercury so dense compared to other terrestrial planets? Why does it have a magnetic field? What is its history? Are there volcanoes on its unseen side? Without an atmosphere, how does it support a magnetosphere? What is the origin of its tenuous exosphere?

Scientists hope that many of these questions will be answered by BepiColombo. Mysterious Mercury awaits.
