The Rosetta lander, given the name Philea, is to touch down on the comet's surface in November and "remain operational through the end of 2015....A drilling system will obtain samples down to 23 cm below the surface and will feed these to the spectrometers for analysis, such as to determine the chemical composition. Other instruments will measure properties such as near-surface strength, density, texture, porosity, ice phases and thermal properties...In addition, instruments on the lander will study how the comet changes during the day-night cycle, and while it approaches the Sun."

The lander is being called Philea for Philea Island in the Nile where an obelisk was found that supplemented the use of the Rosetta Stone in the deciphering of hieroglyphics.

The cost of the mission is 1.3 billion Euros ($1.75 billion at current exchange rates) and ESA asks the question: "Why spend such a huge amount of public money on studying remote stones in space?"

ESA responds: "ESA's task is to explore the unknown. In the case of Rosetta, scientists will be learning about comets, objects that have fascinated mankind for millennia" and "are thought to be the most primitive objects in the Solar System, the building blocks from which the planets were made. So Rosetta will provide exciting new insights into how the planets, including Earth, were born and how life began."

There can be things that can still go wrong on the mission. Gases from the comet could affect Rosetta flying with it. Philae could fail to get hooked to the comet, although a "harpoon" system has been devised for it to anchor itself to the comet's surface.

But if the Rosetta mission is a success it will be a superb example of a space mission that represents no nuclear threat to life on Earth and of a quest with the highest of purposes--exploring the mysteries of the Solar System and the origins of life.
