Launch Recap: Mercury-Atlas 7 – Aurora 7
The launch of Mercury-Atlas 7, featuring astronaut M. Scott Carpenter aboard the Aurora 7 spacecraft, occurred on May 24, 1962, at 7:45:16 EST from Cape Canaveral. This launch was notable for its precision and the minimal issues faced, marking another successful step in the United States’ space exploration efforts.
Countdown and Launch Conditions: The countdown to launch proceeded almost flawlessly. A last-minute hold of 45 minutes was implemented at the T-11 minutes mark, aimed at ensuring optimal camera coverage for the event and allowing time for aircraft to assess the atmospheric refraction index around Cape Canaveral. This brief pause ensured that all conditions were ideal for a successful launch.
Vehicle Specifications and Performance: The launch vehicle, Atlas D, which was designated Atlas 107-D, introduced subtle modifications from its predecessor, which was used in the MA-6 mission. Notably, it retained the insulation bulkhead and featured a slightly reduced staging time, from 131.3 to 130.1 seconds post-liftoff, optimizing the spacecraft’s ascent into orbit.
The performance of the launch vehicle was exceptional, adhering closely to the pre-planned conditions. The sustainer engine cut off (SECO) occurred at T+5 minutes, 10 seconds, confirming that all spacecraft and launch vehicle systems were fully operational and performing as expected.
Anomaly During Launch: The only anomaly noted during the launch involved the abort sensing and implementation system (ASIS). Specifically, Hydraulic switch no. 2 for the sustainer engine inadvertently moved to the abort position 4 minutes and 25 seconds after liftoff. This was attributed to a faulty pressure transducer (H52P) in the sustainer hydraulic accumulator, which erroneously indicated a drop in pressure from 2,940 psia to zero between 190 and 312 seconds after liftoff.
Fortunately, another transducer within the sustainer control circuit maintained correct pressure readings, and the switch did not trigger any premature actions, allowing the mission to proceed normally post-SECO.
This launch of Aurora 7 was a testament to the robustness of the Atlas launch system and the meticulous preparations by the launch team, which contributed significantly to the success of Carpenter’s orbital flight.
