Media Invitation – Follow-up on the Deep Impact

This is a ‘media only’ event.

ESO Headquarters

Garching bei München, Germany

4-5 July 2005

Be where the action is! Share with all European cometary specialists the excitement at the time of the impact and see how they prepare and obtain the follow-up images and spectra

On July 4, 2005, the NASA Deep Impact spacecraft will visit Comet 9P/Tempel 1. It will launch a 360 kg impactor that is expected to produce a crater on the surface of the comet and a plume of gas and dust.

This experiment will be the first opportunity to study the crust and the interior of a comet. As the material inside the comet’s nucleus is pristine, it will reveal new information on the early phases of the Solar System. It will also provide scientists with new insight on crater physics, and thereby give a better understanding on the crater record on comets and other bodies in the Solar System. The scientific outcome of the experiment depends crucially on pre-impact and follow-up observations.

ESO will actively participate in the post-impact observations. As soon as Comet 9P/Tempel 1 is visible after the impact from Chile, and for a whole week thereafter, all major ESO telescopes will be observing Comet 9P/Tempel 1, in a coordinated fashion and in very close collaboration with the space mission’ scientific team. Among all observatories, the ESO La Silla Paranal Observatory will thus provide the most complete coverage of this one of its kind event.

First images of ESO telescopes will be obtained shortly after midnight – European time – on the night of July 4 to 5 and will be directly made available on this web site. Scientists expect the effects of the impact on the comet to be visible only several hours after the impact itself. Therefore, the observations by ESO telescopes will be among the most important.

To allow journalists to share these unique moments, ESO will open its door to the media on July 4 and 5. The media centre at ESO’s HQ in Garching will have live links with ESO’s observatories in Chile – La Silla and Paranal – as well as with the ESA/ESTEC (NL) control centre.

Additional information on the Deep Impact at ESO activities is available at http://deepimpact.eso.org ESO HQ will be open:
