foreword Jörg Feustel-Büechl Foreword 1 ESA Director of Manned Spaceflight and Microgravity Jörg Feustel-Büechl The recent successful flight of ESA /node-2 aboard a Taxi represents the fourth European mission Columbus & Node-2 4 to the International Space Station, following those of Umberto Bernardo Patti & Daniele Laurini Guidoni, Claudie Hagnieré and Roberto Vittorio.This Belgian- sponsored flight was of double importance. Firstly, it took payloads another European to the Station and had a large scientific ESA Plans for Future ISS 6 programme of 23 experiments that kept De Winne and his External Payloads colleagues very busy. Secondly, we established in the Erasmus Giacinto Gianfiglio building at ESTEC in The a Taxi Operations Coordination Centre (TOCC) to coordinate the scientific microgravity programme between our American and Russian partners and Precious Seconds of Microgravity8 the scientists at the Belgian User Support Operations Centre (USOC) in . Indeed,TOCC is a precursor for our USOC operations in the Columbus era. The Station is in excellent technical shape and, with Training for STS-116 10 De Winne’s mission, we had the 32nd flight to the ISS.There Graham T. Biddis have been no major problems since the first Station element, Training for ISS 12 , was launched in November 1998. Compared with Hans Bolender et al. previous international undertakings, there has never been anything of such magnitude and it really is making excellent arms . Considering that elements are developed and built Advanced Respiratory 14 continents apart, and that they never meet each other until Monitoring System that first contact in space, it is really a world-class Ing Oei & Marine Le Gouic achievement.We can congratulate everyone involved in the Station’s development! atv As far as the overall status of the Station is concerned, we ATV: Rendezvous with ISS 17 took a very important step at the Space Station Control Board Heinz Wartenberg & Patrice Amadieu (SSCB) on 14/15 October in agreeing to launch the first Automated Transfer Vehicle (ATV) ‘Jules Verne’ on research 27 September 2004, followed closely by our Columbus Research in Destiny 20 laboratory on 7 October 2004. Columbus will be launched Graham T. Biddis with four or five scientific racks and one or two external platforms.This will enable Columbus to perform an attractive recent & relevant research programme despite there being only three Station News 22 crewmembers at that time, helped by a number of the research facilities being largely automatic.The launch Directorate of Manned Spaceflight and Microgravity Direction des Vols Habité et la Microgravité foreword

Frank De Winne working agreements were endorsed by the Multilateral addressing the problem gives me a measure of with the Microgravity Science Control Board (MCB) on 15 October, so we are optimism that we will restabilise the Station Glovebox aboard the Station’s now entering the final phase of preparing for programme in the coming months.

Although that is a year Columbus, and Robert Lainé for ATV, who have later than originally planned, it is still the major tasks of coordinating all the activities acceptable. It also means that, with the and schedules, and making sure that Columbus launch in October 2004, we have everything – from the space segment to the good utilisation prospects: we expect to spend ground segment – is ready to support end-to- the rest of 2004 in commissioning Columbus end operations when the two elements join before gradually building up utilisation in 2005. the Station. This is only marginally slower than the original The MCB also addressed the studies into the plan because only ESA and NASA have research various option paths towards an acceptable modules at the Station in the period up to End-State of the Station. Progress has been less 2007, when Japan’s module arrives. Our than expected so the Partners, under Chairman utilisation priorities – and those of our Partners Fred Gregory (the responsible NASA Deputy – are well-defined, so we know precisely what Administrator) decided on an accelerated plan needs to be done in the years to come. to define the option paths by early December. In respect of ESA astronaut opportunities, On 6 December there will be a Heads of Agency meeting and we hope to take a big step forward in defining the way forward to achieve an attractive Station End-State. Since the October MCB, we have seen good progress that gives me hope that by the December meeting we will at least know what is the right ‘option pass’ even though we might not have a final decision. (‘Option pass’ means that the End-State would be defined but that the configuration options in that End-State remain to be further detailed.) The final End-State goal will then entail further work before we can select a final configuration, which is expected on Station for early 2003. I hope that this will provide the final clarification on the configuration sometime in February/March 2003 and in time Frank De Winne (left) with for the next ESA Ministerial Conference.The his Soyuz colleagues.(NASA) way our Partners – and particularly NASA – are 2

In reality, the blood pressure is a continuous signal. One of the ARMS instruments, Portapres, continuously measures the blood pressure at finger level using a clever combination of an applied external pressure through a finger cuff and light controls. To measure the electric activity of the heart, an electrocardiogram (ECG) is used. For the ARMS experiments where only the heart rate and rhythm are important, a 3-electrode ECG is recorded using the Portapres.

burn fails at S3, then ATV naturally returns to S2 in another half-orbit.

Final Approach and Docking Between S3 and docking, ATV approaches on a ‘forced’ translation along the ISS velocity vector to the docking port at the aft end of Zvezda. ‘Forced’ means that, in addition to the 220 N thrusters propelling ATV towards the ISS, perpendicular thrusters are firing towards Earth to stop the orbit rising. To ensure proper capture and acceptable docking loads, ATV’s docking probe has to meet Zvezda’s docking cone within a radius of 10 cm and a lateral velocity of less than 2 cm/s. To meet these conditions, the relative navigation during final approach is based on ATV’s optical sensors, with corresponding passive target patterns close to Zvezda’s port. While measurements from the Videometer primary sensor are used in the active guidance, navigation & control (GNC) loops to control ATV’s motion, the information provided by the Telegoniometer secondary sensor is provided to the Flight Control Monitoring (FCM) system to supervise the performance of the active loop.

Principle of the Videometer The Videometer delivers range and line-of- sight angles to the GNC system, and, from within 30 m, relative attitude angles, based on triangulation. A diverging laser beam emitted by diodes on the ATV front cone towards Zvezda is returned by a pattern of reflectors, imaged by a CCD.The pattern size provides the range, its position on the CCD yields the line-of- sight angles, and its apparent shape gives information about the relative attitude angles.

Europe’s first ISS Education Kit for students aged 12-15.

ESA has published an ISS Education Kit to meet the requirements for teaching Space and subjects related to the ISS to European students, aged 12-15. The kit is available only in English and includes simple, modular and interdisciplinary material based on existing European curricula, making it suitable for teaching a wide range of subjects. If you work in the education sector and are prepared to give feedback by mid-January 2003 on the content of the kit then please contact Solveig Pettersen at Tel: +31 (0) 71 565 5755, Fax: +31 (0) 71 565 4499 International Space Station or Email: [email protected]

The main objectives of the kit are to: • Introduce the ISS as a motivating and ideal tool for teaching; • Increase the awareness and interest in science and technology research in space among the youth; • Stimulate curiosity and creativity through active participation; • Highlight the important contributions being made by space technology and science to the well-being of society; • Focus on future, possible areas of space research and technology, as well as the importance of international cooperation and cross-cultural interaction.
