"There is some new condition we do not know about," Bramwell said, in a sort of puny panic. "There is something in space which is working to destroy us! Here! Send this message back to Earth!" McCauley took the slip of paper on which words were written in an erratic, spidery hand. "But I think you are making noises!"
Bramwell pulled himself back into his soundproof half of the ship. The door closed behind him, but not quite in time to cut off the beginning of an agitated whimpering sound.
McCauley pushed the beam-on button. He should have checked the time, Earth time, to see if Canaveral were on the side of Earth from which it could pick up the beamed message from space. It wasn't, but he didn't think to check. He read, in a monotone, the message Bramwell had written out:
I feel the purpose impossible probable effect similar to X-rays with this is vital to further but I have no instruments.
Bramwell.
He was vaguely puzzled but he read it faithfully. Then, without checking for reception, he turned off the transmitter. He went back to the painful task of trying to make the ship's log entry at which he'd been working for a long time. He assured himself that though the message did not mean anything to him, they'd understand it back on Earth.
But they didn't. It didn't get back to Earth. The Venus ship had been pointed very accurately so that the parabolic reflector for the tight beam to Earth was perfectly aligned. But Bramwell had protested the faint, faint hum of the gyros which kept the ship pointed correctly. McCauley had turned them off. He'd meant to re-align the ship for each period of communication, but his mind was confused and he forgot.
Earth had received no message from the Venus ship for six days past. There was consternation in the Space Service.
It wouldn't have lessened any had Bramwell's message been picked up. He'd meant to say that he felt that achievement of the Venus ship's purpose was impossible because of something which doomed the men in it. He thought it probable that some previously unnoticed effect of radiation, perhaps similar to X-rays, was destroying their capacity to think. This effect should be studied. It was vital to further space exploration. But he had no instruments that could detect it.
