Rationale. The mark is literally the initial: two rising strokes form the peak of an "A," and the counter's crossbar anchors it as a letter — so the glyph reads as both AstraRad's first letter and an upward apex of precision. A four-point star-spark (an aster, "little star") rides the tip, fusing Astra (star) with Rad (ray/emission) at the single highest point of the letterform. It stands alone as a favicon at 16px, locks tightest of all concepts into the wordmark by replacing the leading "A," and stays fully legible in a single ink.
