Huygens Probe Set to Detach from Cassini Orbiter Tonight 24 December 2004
Update: Huygens Probe Set to Detach From Cassini Orbiter Tonight 24 December 2004 mission is approximately $3 billion. Many of these sophisticated instruments are capable of multiple functions, and the data that they gather will be studied by scientists worldwide. Aerosol Collector and Pyrolyser (ACP) will collect aerosols for chemical-composition analysis. After extension of the sampling device, a pump will draw the atmosphere through filters which capture aerosols. Each sampling device can collect about 30 micrograms of material. Descent Imager/Spectral Radiometer (DISR) can take images and make spectral measurements using sensors covering a wide spectral range. A few hundred metres before impact, the instrument will switch on its lamp in order to acquire spectra of the surface material. The highlights of the first year of the Cassini- Doppler Wind Experiment (DWE) uses radio Huygens mission to Saturn can be broken into two signals to deduce atmospheric properties.

CEAS Quarterly Bulletin Talented Engineers Are Needed

However, surprisingly, while we are full in course of the election campaign for the renewal of the European Parliament, we hear almost nothing about education and culture, and we see no proposals from the candidates on how to prepare the students and young professionals to live in an increasingly integrated Europe. The question is a very broad and difficult one, due to the large number of Member States and the diversity of languages and cultures; but this is all the more reason to concentrate great efforts on it. In the aerospace sector, the projects, more and more complex, are developed across several national borders and include the highest technologies. So, to overcome the Jean-Pierre Sanfourche numerous challenges which confront us in a fierce world-wide aerospace market, Editor-in-Chief, CEAS Quarterly Bulletin talented engineers are needed. Unfortunately, in the past two or three decades within Europe, there have been clear indications that the most brilliant students pre- fer careers in business and finance to those in science, technology and engineering. Action is clearly necessary to reverse this trend by taking the measures that will CONTENTS allow us to attract and then retain the best talent in the air and space activities.

Moon Minerals a Visual Guide
Moon Minerals a visual guide A.G. Tindle and M.

Early days were spent using LEGO robots to automate a rotating microscope stage thanks to the efforts of our colleague Peter Whalley (now deceased). This automation speeded up image capture and allowed us to take the thousands of photographs needed to make sizeable (Earth-based) virtual microscope collections. Virtual microscope methods are ideal for bringing rare and often unique samples to a wide audience so we were not surprised when 10 years ago we were approached by the UK Science and Technology Facilities Council who asked us to prepare a virtual collection of the 12 Moon rocks they loaned out to schools and universities. This would turn out to be one of many collections built using extra-terrestrial material. The major part of our extra-terrestrial work is web-based and we The authors - Mahesh Anand (left) and Andy Tindle (middle) with colleague have build collections of Europlanet meteorites, UK and Irish Peter Whalley (right). Thank you Peter for your pioneering contribution to the Virtual Microscope project. We could not have produced this book without your earlier efforts. 2 Moon Minerals is our latest output.

A Clearer Final Frontier of the Sentinel Family of Earth-Monitoring Satellites
COMMENT BOOKS & ARTS Station. His examination of other astro- nomical and exploration cooperation efforts is somewhat cursory, and there are small errors. The Rosetta mission of the Euro- pean Space Agency (ESA), for instance, is ROGER HARRIS/SPL not a solar mission, but instead will rendez- vous with and observe a comet. The lunar probe Chandrayaan-1 was a collaboration between India, ESA, NASA and Bulgaria; and unmentioned is the ground-breaking Double Star Sino-European joint mission. Failures in cooperation offer many lessons, and Moltz looks at the International Solar Polar Mission almost 25 years ago, as well as the United States’ 2012 pull-out from collaboration with ESA on Mars explora- tion. However, he misses the pivotal case of the International Gamma-Ray Laboratory (INTEGRAL), launched in 2002, the absence of expected levels of US support for which led to the first close ESA Science Programme cooperation with Russia. The distinction between cooperation and competition had, however, emerged decades before, with US refusal to launch the Franco-German com- munications satellite Symphonie. Europe learnt that it had to go it alone in using space for commercial or near-to-market purposes. Satellite deployment must be regulated to keep space usable and safe. Moltz accepts that space is important to commerce, but readers might query whether SPACE POLICY he sees how this may drive regulation. The European Union, the largest economic grouping in the world, is this year launching multiple spacecraft; these include members A clearer final frontier of the Sentinel family of Earth-monitoring satellites. The move is economic, and the use David Southwood finds that a study on safeguarding of space is evolving and increasingly focused space is shorter on cooperation than conflict. -

Mars Exploration - a Story Fifty Years Long Giuseppe Pezzella and Antonio Viviani
Chapter Introductory Chapter: Mars Exploration - A Story Fifty Years Long Giuseppe Pezzella and Antonio Viviani 1. Introduction Mars has been a goal of exploration programs of the most important space agencies all over the world for decades. It is, in fact, the most investigated celestial body of the Solar System. Mars robotic exploration began in the 1960s of the twentieth century by means of several space probes sent by the United States (US) and the Soviet Union (USSR). In the recent past, also European, Japanese, and Indian spacecrafts reached Mars; while other countries, such as China and the United Arab Emirates, aim to send spacecraft toward the red planet in the next future. 1.1 Exploration aims The high number of mission explorations to Mars clearly points out the impor- tance of Mars within the Solar System. Thus, the question is: “Why this great interest in Mars exploration?” The interest in Mars is due to several practical, scientific, and strategic reasons. In the practical sense, Mars is the most accessible planet in the Solar System [1]. It is the second closest planet to Earth, besides Venus, averaging about 360 million kilometers apart between the furthest and closest points in its orbit. Earth and Mars feature great similarities. For instance, both planets rotate on an axis with quite the same rotation velocity and tilt angle. The length of a day on Earth is 24 h, while slightly longer on Mars at 24 h and 37 min. The tilt of Earth axis is 23.5 deg, and Mars tilts slightly more at 25.2 deg [2]. -
