NASA has postponedÂ Orbital ATK‘sÂ nextÂ cargo resupply missionÂ to the International Space Station to address booster problems onÂ the launch vehicle that will be used to launchÂ a company-built spacecraft, Space News reported Wednesday.
Space News’ Jeff FoustÂ quotedÂ Robyn Gatens, deputy director of NASA’sÂ ISS division, as saying the investigation on the booster engine for theÂ CygnusÂ OA-7Â mission willÂ push back the launchÂ no sooner thanÂ mid-April.
The OA-7 spacecraft was originallyÂ scheduled to launchÂ in mid-March aboard a United Launch Alliance-builtÂ Atlas 5Â rocket but the liftoff was delayedÂ forÂ several days due to a hydraulic issueÂ in the rocket’s first stage and a technical problem withÂ ground support equipment.
Foust reported the delay of the OA-7Â launchÂ will also affect aÂ spacewalk initially scheduledÂ to take place on the station inÂ the first week of April.
TheÂ mission will deliver supplies to the ISS as part ofÂ along with an avionics box that astronauts Peggy Whitson and Thomas Pesquet will installÂ on the exterior of theÂ orbiting laboratory, according to the report.
Orbital ATK’s sixth cargo delivery mission, designated OA-5, delivered nearly 5,300 pounds of supplies, laboratory equipment and scientific experiments to the space stationÂ in NovemberÂ as part of the company’sÂ Commercial Resupply Services-1 contract.
