Earth Flyby
Fifteen burns of Suisei's 3 N motors during the period of April 5–10, 1987, yielded a 65 m/s velocity increase for a 60,000 km Earth gravity assist swingby on August 20, 1992, although the craft was then lost behind the Sun for the summer.
The hydrazine fuel was depleted on February 22, 1991. Preliminary tracking indicated a 900,000 km flyby had been achieved.

Famous quotes containing the word earth:
“Laugh, and the world laughs with you;
Weep, and you weep alone,
For the sad old earth must borrow its mirth,
But has trouble enough of its own.”
—Ella Wheeler Wilcox (1850–1919)
