Chandra slips, space shuttle runs a risk

Tony Reichhardt1

The launch date for the US$2 billion Chandra X-Ray Observatory, originally scheduled for August 1998, was set back from May to July 1999 last week, the fourth postponement in just over a year.Most previous delays had involved problems with the spacecraft, but the new delay has been caused by space shuttle missions being rescheduled to launch part of the International Space Station in May.
