These concerns were virtually unknown outside NASA. But the striking dual mission launched by the Soviet Union in August led some to wonder if the United States had any hope of flying the first rendezvous mission. Vostok III, piloted by Major A. G. Nikolayev, lifted off on 11 August, followed a day later by Lieutenant Colonel P. R. Popovich in Vostok IV. The two spacecraft came close enough to each other to spur some talk of rendezvous. With no means of maneuvering their spacecraft, however, the two cosmonauts could not match orbits or speeds. The Soviet Union had shown only that it could launch two spacecraft in quick succession, so there was still hope for the maneuverable Gemini spacecraft to achieve the first rendezvous, if it survived its troubles.1
