ACROSS 1. Launched in 1992, this ISTP satellite studies the interaction between the solar wind and the magnetosphere in Earth's magnetic tail. 5. What heats the solar corona? What causes solar wind? What are the characteristics of polar structures? This satellite should tell starting in 2007. (abbr.) 6. To study the energy, composition and charge states of particles in space and in the magnetosphere, this satellite was launched in 1992. 7. What do you see? These three satellites (the last was launched in 1978) looked at solar-terrestrial relationships and solar wind structure just outside Earth's magnetic field. 8. This satellite is set for launch in the near future, followed by investigation of the energetics of the mesosphere and lower thermosphere in Earth's atmosphere. 10. After its launch in 1980, this satellite studied solar activity, especially flares, during solar maximum. 11. Substorms, aurora, and energy input are all studied by this ISTP satellite, launched in 1996. 13. For forecasts and alerts about space weather disturbances, scientists rely on NOAA's ______ Center. (abbr.) 14. This satellite is quite an adventurer -- it studies the high-latitude heliosphere in a unique solar polar orbit. 16. Six satellites, launched from 1964 to 1972 to study the atmosphere, magnetosphere, and space between the Earth and Moon, were part of the _____ program. 18. Launched in 1999, this student satellite may become man's best friend as it studies the ionosphere and the effects of space weather. 19. The sequel to Yohkoh, this satellite planned for launch in 2004 will investigate the interaction between the Sun's magnetic field and corona. 20. With Gemini on their logo, these two satellites (to be launched in 2002 and 2004) will provide stereo images of Earth's magnetosphere. |
DOWN 1. This series of geostationary satellites launched by NOAA and NASA carry instruments that measure x-rays, energetic particles, and the magnetic field. 2. The eighth of these "mischievous" satellites was launched in 1978 to study magnetic fields and plasmas in the magnetotail, magnetosheath, and solar wind. 3. NASA launched this "number-one" satellite in 1997 to study the composition and origin of solar and galactic matter. 4. Launched in 1994, this ISTP satellite studies the properties of the solar wind. 5. Proposed for launch in 2003, these two satellites will orbit the Sun on either side of Earth to produce a double-image reconstruction of coronal mass ejections. 6. New information on the structure of the Sun, the solar atmosphere, and the origin of solar wind has resulted from this ISTP satellite, launched in 1995. 7. Since its launch in 2000, this satellite has taken pictures and studied the response of the magnetosphere to solar wind. 8. This satellite follows closely the 3-D magnetic structures on the Sun and investigates coronal heating and the triggers of flares and CMEs. 9. As the name suggests, this satellite (launched in 1997) studies the magnetosphere around the Earth's equator. 12. The second version of this mission launches its satellites in mid-2000: four spacecraft that will study the interaction between the solar wind and the magnetosphere. 13. This student satellite, launched in 1998, measures changes in nitric oxide density in the upper atmosphere as a result of energy from the Sun. 15. Also known as Solar-A, this Japanese satellite began its mission of studying x-rays and gamma rays from the Sun in 1991. 17. From 2001 on, this satellite will help scientists understand processes that take place during high-energy flares. |
