Countdown to launch

This Falcon 9 Block 5 mission by SpaceX is scheduled to launch from Cape Canaveral SFS, FL, USA. This resupply mission targets Low Earth Orbit. The Falcon rocket family has been instrumental in modern space access, representing decades of engineering refinement in propulsion, guidance systems, and structural design.
Every rocket launch involves precise coordination between the launch vehicle, payload, ground systems, and range safety. The launch window is carefully calculated based on orbital mechanics — for missions targeting the International Space Station, the window may be only seconds long, while interplanetary missions can have windows lasting weeks. Weather conditions, including upper-level winds, lightning risk, and cloud ceiling, are monitored up until the final moments before ignition. Space weather conditions from solar activity can also affect launch decisions, as high radiation levels may pose risks to satellite electronics.

This is the 24th flight of the Orbital ATK's uncrewed resupply spacecraft Cygnus and its 23rd flight to the International Space Station under the Commercial Resupply Services contract with NASA.

Commercial Resupply Services
Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station.The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences for eight Cygnus flights, covering deliveries to 2016. The Falcon 9 and Antares rockets were also developed under the CRS program to deliver cargo spacecraft to the ISS.

International Space Station
The International Space Station programme is tied together by a complex set of legal, political and financial agreements between the sixteen nations involved in the project, governing ownership of the various components, rights to crewing and utilization, and responsibilities for crew rotation and resupply of the International Space Station. It was conceived in 1984 by President Ronald Reagan, during the Space Station Freedom project as it was originally called.
