Corrected entry: When they have to travel through space from the Icarus I to the Icarus II, one of the men must remain to open the lock gate. Why don't they choose the man with the spacesuit [Capa] to open it? He could do it and after that, fly to the other spaceship.
Corrected entry: As they approach Mercury the planet moves from the right to the left in front of them. Given the angle, direction towards the sun, and the counterclockwise rotation of all planets this is entirely impossible. The planet would move from left to right in front of them.
Corrected entry: Cappa's last message to his family is seen to arrive directly before the sunshine brightens and the end credits roll, a long time after it was sent. Although sound waves travel at a low speed (about 340 m/s), all electromagnetic radiation (including radio transmissions) travels at the speed of light (300 000 000 m/s). Thus the eight minute travel time specified for light emanating from the sun would also apply to radio communications.
Corrected entry: In the scene where Capa is the only man in the spacesuit and two other crew members have to jump with him through space, the two other crew members would not survive. The difference in pressure between space (0kg/cm^2)) and Earth (1kg/cm^2) would surely cause the astronauts' bodies to leak or explode. Therefore Harvey would not even have time to become frozen: he would sooner begin to leak and be torn apart by the pressure inside of him. The same goes for the other guy (the one who makes it without the suit).EpicFishFingers
Corrected entry: The crew are ongoing with the repairs to the payload shield, and the oxygen garden catches fire by reflected sunlight from the damaged com towers. The big plot hole here would be: why design such a critical area with pointless windows, which only expose the very critical area needed for the human crew to survive, to possible but unlikely destruction? There is no reason to have windows, as the sunlight would be destructive. It did, in fact, cause the destruction of the oxygen garden in the first place.
Corrected entry: Capa escapes the Icarus II spacecraft using the spacesuit to reach the bomb payload. When the bomb payload begins to move away from Icarus II, the rocket thrusters damage the Icarus II spacecraft to the point of destruction. When you see the spaceship explode you can see that the front part of the craft where the shield dish is has no thrusters or engine in which to move away from the sun and the bomb payload. I assume that the craft designers orginally intended for the crew to be able to survive the mission and escape, but how is this possible if there is no engine or thrusters for the ship to move away from the sun? Turning the ship round is no option, as the sun would destroy the ship, hence the need for the dish which acts as a shield.
Corrected entry: In order for a star to die, it must first go through a "Red Giant" stage, after which it would either become a dwarf star or implode, thereby creating a black hole. Nevertheless, Earth would be destroyed in the Red Giant stage because the stars growth would envelop the planet.
Corrected entry: There's something a bit unfortunate about the name "Icarus". Why would they give the spaceship a name of a Mythological character who died because he approached too close to the Sun?
