The Times of Israel reports: A hitch in computer systems Monday evening caused an Israeli lunar spacecraft to miss a scheduled adjustment in its trajectory en route to the moon, engineers reported on Tuesday.

The maneuver by the Beresheet craft was postponed after the space vehicle’s on-board computer executed an independent restart. As a result, the craft automatically canceled an engine burn scheduled to keep it on track for an April lunar landing.

“At the moment we are not very worried. Of course it isn’t nice, but we are still optimistic,” said SpaceIL CEO Dr. Ido Anteby.
