Artemis II astronaut breaks silence with historic four-word remark on radio

You don’t have to be an avid space fanatic to be familiar with terms like “Houston, we have a problem” and “One small step for man, one giant leap for mankind”.

Humanity’s forays into the black beyond thus far have been the stuff of legend, the nuts and bolts of the narratives prettied up and offered to the masses through countless films, books, and documentaries.

The current Artemis II mission looks to have already taken its place in the history books. NASA astronauts Christina Koch, Reid Wiseman, Victor Glover, and the Canadian Space Agency’s Jeremy Hansen launched on Wednesday (1 April) aboard a 322-foot rocket, beginning their journey beyond Earth’s orbit.

Part of the mission’s significance is that it was to break the record for human spaceflight’s farthest distance from Earth, previously set by the Apollo 13 mission in 1970.

Needless to say, a great many people have been following the Artemis’ progress. Arguably the most nerve-wracking period of the journey so far was when the crew passed around the far side of the moon, losing contact with Mission Control in Houston, Texas for 40 minutes.

The period of lost contact was preplanned, with the technology being used to communicate between the crew and Mission Control blocked by the moon.

Artemis pilot Victor Glover had revealed previously that they would spend the 40 minutes praying that they would ‘get back in contact with the crew’.

Fortunately, the gap in communication didn’t drag on for any longer than it needed to. Mission specialist Christina Koch’s words could be heard without issue when the computers on board Orion came to life at exactly the right time according to schedule.

The first four words she said were: “Houston, Integrity, comm check,” followed by “It is so great to hear from Earth again.”
