Mechte navstrechu (1963)

Upon hearing a song about the romance of space flight, aliens on the distant planet of Centuria decide to visit Earth. Their spacecraft suffers a malfunction, and they are forced to land on Mars. They do manage to send a distress video message to Earth via a small capsule that lands in the ocean. This inspires Earthlings to send a rescue vessel, the Ocean. They find the crashed alien spacecraft with one dead crew member still aboard. Evidence leads them to suspect that there are two others somewhere. Because Ocean has only enough fuel for a return flight, a second Earth ship, the Meteor, is sent. It will land on Phobos and survey mars for the two missing aliens. Eventually, the Meteor's crew find a small alien craft on Phobos itself. It must have been their escape craft. One of the two aliens, a woman, is still alive. This presents a problem. The Meteor does not have enough fuel to return. They always planned to use their 2-person shuttle to get down to the Ocean for the return flight. One of the Earth crew opts to remain behind on Phobos so that the alien woman can be taken to Earth. The shuttle crash lands near the large alien craft and the Earth pilot carries the unconscious alien woman to the Ocean where they can all return to Earth.
