\nTD-1A<\/a> was Europe’s first three-axis-stabilized spacecraft, designed “to make a systematic sky survey in the ultraviolet and high-energy regions of the spectrum.” Two instruments pointed at the sun and measured its x-ray and gamma ray output; five other instruments scanned the sky to measure “ultraviolet, x and gamma rays, and heavy nuclei.”<\/p>\n
