Space Shuttle UHF communications performance evaluation

Computational investigations and experimental measurements were performed to evaluate the Space Shuttle UHF communication system performance for payload bay antenna at the proposed new location. To insure adequate communication coverage at relocated new location, the link margin for the Extravehicular Activity (EVA) astronauts and between Space Shuttle Orbiter and International Space Station (SSO-ISS) during rendezvous were analyzed. The multipath effects from the vehicle structures surrounding the antenna were investigated. The Radio Frequency (RF) electromagnetic radiation to the Orbiter Docking System (ODS) pyrotechnics was also analyzed to ensure the EMC/EMI compliances.

The Japanese Experiment Module

This paper describes Japanese Experiment Module (JEM) which is a Japanese contribution to International Space Station (SS) Program. First half of phase B study of JEM was completed last March successfully. JEM primary function and basic configuration has been established. JEM consists of a Pressurized Module (PM), an Exposed Facility (EF), a scientific/equipment airlock, a local remote manipulator, and an Experimental Logistic Module (ELM). With all those hardware elements, JEM will accommodate general scientific and technology development research (some of which are to utilize the advantage of microgravity environment), and also accommodate control panels for the Space Station Mobile Remote Manipulator System and attached payloads.     

Life sciences

Space life sciences research activities are reviewed for 2003. Many life sciences experiments were lost with the tragic loss of STS-107. Life sciences experiments continue to fly as small payloads to the International Space Station (ISS) via the Russian Progress vehicle. Health-related studies continue with the Martian Radiation Environment Experiment (MARIE) aboard the Odyssey spacecraft, collecting data on the radiation environment in Mars orbit. NASA Ames increased nanotechnology research in all areas, including fundamental biology, bioastronautics, life support systems, and homeland security. Plant research efforts continued at NASA Kennedy, testing candidate crops for ISS. Research included plant growth studies at different light intensities, varying carbon dioxide concentrations, and different growth media. Education and outreach efforts included development of a NASA/USDA program called Space Agriculture in the Classroom. Canada sponsored a project called Tomatosphere, with classrooms across North America exposing seeds to simulated Mars environment for growth studies. NASA's Office of Biological and Physical Research released an updated strategic research plan.

The European Columbus Programme

This paper describes the current status of the COLUMBUS Programme, Europe's contribution to the U.S. Space Station, which is being studied under contract to the European Space Agency. Twelve European nations are involved in and are contributing to this new space undertaking. The elements of the COLUMBUS Space Segment presently being considered by ESA are a Pressurized Laboratory Module (4 segment), permanently attached to the U.S. Space Station, dedicated to materials science, fluid physics and compatible life sciences, and a Polar Platform, configured to accommodate Earth observation, meteorology, communications and space science payloads. The reference launch vehicles are the Space Shuttle for the attached Module and Ariane 5 for the Polar Platform. The more recently added COLUMBUS flight configuration, the Man-Tended Free Flyer (MTFF), consists of a combination of two programme elements, the Resource Module and a 2-segment Pressurized Module. It is designed to provide all required resources and services to the various payloads in a continuous microgravity environment to perform material science, fluid physics and compatible life sciences experiments. The MTFF is carried into orbit by the European launcher Ariane 5. As an option, studies of an enhanced ground based EURECA carrier as a small co-orbiting platform, launched by the Space Shuttle, will be initiated. The primary function would be to accommodate space science and/or micro-g payloads. These EURECA studies are performed currently outside the COLUMBUS programme scope, and this option is therefore not addressed in detail in this paper.     

The State of Space Weather Scientific Modeling—An Introduction

The discipline of “Space Weather” is built on the scientific foundation of solar-terrestrial physics but with a strong orientation toward applied research. Models describing the solar-terrestrial environment are therefore at the heart of this discipline, for both physical understanding of the processes involved and establishing the capability to predict the consequences of these processes. This issue of Space Science Reviews contains four topical reviews on primarily European scientific progress in understanding and modeling space weather phenomena. The four reviews deal with (i) monitoring, modeling and predicting solar weather, (ii) the radiation environment of the Earth, (iii) solar wind disturbances and their interaction with geospace, and (iv) the upper atmosphere’s response to space weather events.

WSC lectures and plenary sessions focused on future research in space. Among topics discussed are the use of the Hubble Space Telescope to scan for habitable planets and obtain data about the beginning of the universe, new weather satellites, planetary protection from comets or asteroids, exploration and establishment of colonies on the Moon and Mars, medical advances, the role of space exploration in the world economy.     

The Space Weather Forecast Program

This paper describes the Space Weather Forecast Program managed by the Communications Research Laboratory of Japan. It is a long-range program consisting of three phases of five years each. This program emerged after an effort to investigate future needs for space environment prediction. We conclude that solar flares and magnetic storms are two main critical phenomena which will affect human's space activities in the 21st century. The core of the program is to set up a Space Weather Forecast Center which has core facilities: (1) a computer network system; (2) ground facilities for continuous observation of the Sun; and (3) a satellite-based space environment monitoring system. Emphasis is placed upon the necessity of internal cooperation for efficient operation of the Forecast Center.
