Astronaut David Saint-Jacques will become the first Canadian spacewalker in 12 years when he embarks on a roughly seven-hour mission planned for today. Canadian Space Agency robotics flight controllers will provide support while he performs his mission with NASA astronaut Anne McClain. Saint-Jacques’ spacewalk comes on his first posting to the International Space Station. It’s set to begin just after 8 a.m. EDT, and will involve several tasks, including upgrading the station’s communication system and connecting cables to give Canadarm2 an alternative power source.

COAST GUARD STRUGGLING DUE TO OLD FLEET

Reduced search-and-rescue coverage, ferry-service disruptions, cancelled resupply runs to Arctic and coastal communities and nearly $2 million in lost navigational buoys.

AI POISED TO REVOLUTIONIZE HEALTH CARE

Now artificial intelligence is poised to revolutionize key aspects of how doctors practise medicine and the ways in which patients are diagnosed and treated. AI systems, specifically machine learning, have the ability to analyze massive sets of anonymized patient data and look for patterns in a way that the human brain cannot begin to approach.
