Advanced Satellite For Cosmology And Astrophysics
ASCA (formerly named ASTRO-D) is the fourth cosmic X-ray astronomy mission by Japan's (JAXA), and the second for which the United States is providing part of the scientific payload. The satellite was successfully launched on February 20, 1993. The first eight months of the ASCA mission were devoted to performance verification. Having established the quality of performance of all ASCA's instruments, the project changed to a general/guest observer for the remainder of the mission. In this phase the observing program is open to astronomers based at Japanese and US institutions, as well as those who are located in member states of the European Space Agency.

Famous quotes containing the words advanced and/or satellite:
“How oft when men are at the point of death
Have they been merry! which their keepers call
A lightning before death: O, how may I
Call this a lightning? O my love! my wife!
Death, that hath sucked the honey of thy breath,
Hath had no power yet upon thy beauty:
Thou art not conquered; beauty’s ensign yet
Is crimson in thy lips and in thy cheeks,
And death’s pale flag is not advanced there.”
—William Shakespeare (1564–1616)
“Books are the best things, well used; abused, among the worst. What is the right use? What is the one end, which all means go to effect? They are for nothing but to inspire. I had better never see a book, than to be warped by its attraction clean out of my own orbit, and made a satellite instead of a system.”
—Ralph Waldo Emerson (1803–1882)
