James E. Webb, NASA's new Administrator, reviewed the Gemini program. Project Gemini cost estimates at this point ($744.3 million) had increased substantially over the original estimate of $250 million. Estimated spacecraft cost had risen from $240.5 to $391.6 million; Titan II cost, from $113.0 to $161.8 million; Atlas-Agena, from $88.0 to $106.3 million; and supporting development (including the paraglider program), from $29.0 to $36.8 million. Estimated operations costs had declined from $59.0 to $47.8 million.

Developmental testing began on a new landing device for the CM, one using rockets (mounted on the heatshield) that would be ignited immediately before impact. The current method for ensuring the integrity of the spacecraft during a landing in rough water involved strengthening of the aft structure. The new concept, should it prove practicable, would offer a twofold advantage: first, it would lighten the CM considerably; second, it would provide an improved emergency landing capability.

MSFC informed MSC that the thrust of the H-1 engine was being uprated to 1,000 kilonewtons (205,000 lbs), thus increasing the Saturn IB's payload capability. References: 16 .

The cosmonauts entered open space via the air-lock of Kvant-2 at 10:44 GMT. The Germatizator experiment, the use of a special glue to seal off cracks on the outside surface of the complex, was executed according to plan. An inspection of a malfunctioning solar panel on Kvant-1showed that the steering cable to the rotor was burnt through due to a short-circuit and was beyond repair. The cosmonauts dismantled an experimental lightweight solar battery from the outer surface of the SO docking compartment. The last activity was the panorama-inspection, making images of the outside of the complex to enable specialist to analyse the effects of ageing of the material. The hatch was closed on what might have been the last spacewalk on Mir at 15:36 GMT.
