Navy dispatches missile destroyers to New York and Washington, D. Although less technically sophisticated than the NASA instrumentation, they still managed to make useful contributions to solar science. TRACE was launched into a Sun-synchronous orbit on April 2,giving it uninterrupted viewing of the Sun for up to eight months at a time. The Japanese launched a highly innovative solar dedicated spacecraft called Hinotori which means "phoenix" in English on 21 February, that was to rival SMM, especially in its hard X-ray imaging capability. Following launch inSolar Orbiter will begin its journey to the Sun which will require a cruise phase lasting approximately 3.

Some flew the American flag from their front porches and car antennas.
This great interest is, if anything, increasing as modern civilization relies more and more heavily on space-based technologies and their inherent vulnerabilities to the solar-controlled Space Weather. In contrast with all of the OSO spacecraft, the Solar Maximum Mission was 3-axis stabilized so that all of the instruments were pointed at the Sun with arcsecond accuracy and stability. SDO is designed to help understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.
We provide an edited version of the NMC list in Table 1 of spacecraft that have made or are making significant solar observations useful for research in solar physics. Perhaps the most noteworthy scientific result from Yohkoh was the detection of a coronal hard X-ray source in what has become known as the "Masuda Flare. As shown in the figure, all the OSO spacecraft incorporated a "wheel" component spinning at up to 15 rpm to provide pointing stability, and a de-spun platform to carry the imaging instruments pointed at the Sun.

The Boeing is headed to Los Angeles with 64 people aboard. Then in April,in the first of many dramatic spacecraft rescue missions using the Space Shuttle, the aspect system was fixed by the astronauts, and SMM was able to provide 6 more years of excellent solar observations until it re-entered the Earth's atmosphere in December, The solar instruments included high-resolution Bragg crystal spectrometers covering selected wavelength ranges between 1.
Bernhard Fleck. The broad scope and influence of Yohkoh across most of solar physics can be appreciated from the topics included in the different chapters in this proceedings - the quiet Sun, the solar wind, active regions, bright points, flares, CMEs, the solar cycle.

|Launched in April and re-entering the Earth's atmosphere in June 4CGRO covered almost a solar cycle with observations spanning an unprecedented six decades of the electromagnetic spectrum, from X-rays as low as 30 keV to gamma rays at 30 GeV.
Skylab provided many outstanding observations made primarily during the three manned visits in when astronauts tended the instruments and returned the film used to record the images.
TRACE was launched into a Sun-synchronous orbit on April 2,giving it uninterrupted viewing of the Sun for up to eight months at a time. Scientific returns from this mission include the first observations of a halo coronal mass ejection, and the discovery of the association of mass ejections with interplanetary shocks. Bernhard Fleck. The spacecraft was of the Orbiting Solar Observatory OSO type, with a solar-oriented sail and a rotating wheel section.
