Compared with previous ASMs, its salient features are: (1) it has a focusing capability that increases the signal to background ratio by a factor of 3; (2) it has a broad-band width: 200 eV to 15 keV; (3) it has a large X-ray collection area: ~100 square cm; (4) it has a duty cycle of nearly 100%, and (5) it can measure the position of a new source with an accuracy of a few minutes of arc. These features combined open up an opportunity for discovering new phenomena as well as monitoring existing phenomena with unprecedented coverage and sensitivity.9 pages (figures and tables embedded), uses aas2pp4, Contributed paper to "All-Sky X-ray Observations in the Next Decade -- A workshop for ASM and GRB missions in the X-ray Band," March 3-5, 1997, Wako, Saitama, JapanAstrophysicstext
