A number of issues have prevented the Ax-4 mission from getting underway earlier. The launch was first targeted for June 10 but inclement weather forced a delay. June 11 also presented a launch opportunity, but the discovery of a liquid oxygen leak in the Falcon 9 booster prompted engineers to scrub the plan. A launch effort for June 19 was also called off after a leak was discovered in the Zvezda service module at the ISS. A new target date of June 22 was set, but this was also called off to give the mission team more time to evaluate space station operations. Officials are now satisfied that everything is in order, and so the launch can finally take place. Interested in watching the launch and initial stages of the Ax-4 mission?
