Astronauts are among some of the smartest people alive, however one unfortunate event on the International Space Station has shown that even they can get a little confused by new technologies.

A NASA astronaut was caught on camera during a simulcast spacewalk on the ISS having some difficulty with a GoPro video camera he had brought with him.

“Hey Houston, I’ve got a question about the GoPro, real quick,” he asked in a radio message sent back to the NASA control centre in the United States.

“I’m pushing a button and I’m seeing a ‘No SD’. That means - do I need that to record?

“And if it’s recording, is there supposed to be a red light on?”

The astronaut, whose identity remains unknown, appeared to want to record vision of repairs and maintenance he was doing on the ISS when he encountered the issue.

GoPro cameras require an SD memory card to be inserted during use in order for vision recorded on the device to be saved.

The technical difficulty was one that even the astronaut’s colleagues on Earth were a little stumped over.

“I’m told that if it has the card in it, it should have the red light if it’s recording,” one man replied from the Houston control centre.

“(No SD) means no card, we’ll check it though, hang on.”

For the astronaut though, that was enough to leave the technology behind and continue going about his work.

“Well, we can put this one back in the bag then I guess,” he said.
