contract. In June 2016, a NASA Inspector General report had this mission manifested for November 2016. The launch was then put on hold pending investigation of the pad explosion in September 2016, with a tentative date no earlier than January 2017, subsequently set for 18 February. On 12 February 2017, SpaceX successfully completed a static fire test of the Falcon 9 engines on Pad 39A. An initial launch attempt on 18 February 2017 was scrubbed 13 seconds before its 15:01:32 UTC launch due to a thrust vector control system issue in the rocket's second stage, resulting in a 24-hour hold for launch no earlier than 19 February at 14:39 UTC.

The Dragon spacecraft rendezvoused with the International Space Station on 22 February, but its approach was automatically aborted by an on-board computer at 08:25 UTC when a data error was reported in its navigation system. This is the first rendezvous abort by a Dragon spacecraft. The problem was traced to an incorrect data value in the spacecraft's

The error was corrected in this time, during which the spacecraft entered a "racetrack" trajectory around the station to reset its approach. An error-free second attempt resulted in Dragon being captured by the station's

This abort was later revealed in a NASA Inspector General audit to have resulted from incompatibilities between NASA's and SpaceX's software development processes. The CRS-10 mission ended on 19 March 2017. The Dragon spacecraft was detached from the International Space Station by Canadarm2 on 18 March 2017 at 21:20 UTC, moved to a stow position below the station where it stayed overnight, and was released at 09:11 UTC. Dragon performed three departure burns to move it away from the station before conducting a final de-orbit burn at around 14:00 UTC. The spacecraft splashed down in the Pacific Ocean at 14:46 UTC, about southwest from

. CRS-10 carried a total of of cargo to the International Space Station, including of pressurized cargo including packaging and of unpressurized cargo. External payloads on the CRS-10 spacecraft are the SAGE III Earth observation experiment and its Nadir Viewing Platform (NVP), and the U.S. Department of Defense's Space Test Program Houston 5 (STP-H5) package including the Raven navigation investigation and the Lightning Imaging Sensor. Some science payloads include ACME, LMM Biophysics, ZBOT, and CIR/Cool Flames.

Trial of new flight safety system

SpaceX's CRS-10 launch was the "first operational use" of the Autonomous Flight Safety System (AFSS) on "either of

The benefits of AFSS include increased public safety, reduced reliance on range infrastructure, reduced range spacelift cost, increased schedule predictability and availability, operational flexibility, and launch slot flexibility." The system consists of software developed by NASA, the Air Force, and
