Photos: Atlas launch seen from press site

United Launch Alliance called off the launch of a Delta 2 rocket from California’s Central Coast early Tuesday after boats ventured into a restricted safety exclusion zone and engineers ran out of time to resolve a technical problem on the launcher.

An Atlas 5 rocket successfully launched another Cygnus cargo freighter for Orbital ATK Tuesday night, fulfilling the booster’s role of reestablishing America’s resupply link to the International Space Station.

Onboard video cameras captured critical events during the 50th Atlas 5 rocket launch, beaming back views in stunning clarity of staging and spacecraft separation.
