+     HITEN, a small lunar probe, was launched into Earth orbit on January 24,
+     1990. The spacecraft was then known as MUSES-A, but was renamed to Hiten
+     once in orbit. The 430 lb probe looped out from Earth and made its first
+     lunary flyby on March 19, where it dropped off its 26 lb midget
+     satellite, HAGOROMO. Japan at this point became the third nation to
+     orbit a satellite around the Moon, joining the Unites States and USSR.
+
+     The smaller spacecraft, Hagoromo, remained in orbit around the Moon. An
+     apparently broken transistor radio caused the Japanese space scientists
+     to lose track of it. Hagoromo's rocket motor fired on schedule on March
+     19, but the spacecraft's tracking transmitter failed immediately. The
+     rocket firing of Hagoromo was optically confirmed using the Schmidt
+     camera (105-cm, F3.1) at the Kiso Observatory in Japan.
+
+     Hiten made multiple lunar flybys at approximately monthly intervals and
+     performed aerobraking experiments using the Earth's atmosphere. Hiten
+     made a close approach to the moon at 22:33 JST (UTC+9h) on February 15,
+     1992 at the height of 423 km from the moon's surface (35.3N, 9.7E) and
+     fired its propulsion system for about ten minutes to put the craft into
+     lunar orbit. The following is the orbital calculation results after the
+     approach:
+
+	  Apoapsis Altitude: about 49,400 km
+	  Periapsis Altitude: about 9,600 km
+	  Inclination	  : 34.7 deg (to ecliptic plane)
+	  Period	  : 4.7 days
