Over the last few weeks, Canadian Space Agency (CSA) scientists and engineers on the ground in the Payload Telescience Operations Centre (PTOC) supported nine on-orbit science sessions on the International Space Station (ISS). With the help of astronauts, they conducted activities for Canadian science experiments CARDIOBREATH, Space Health and Vascular Aging.

Learn about safe practices for observing a solar eclipse. To prevent serious eye damage, always avoid direct eye contact with the Sun, especially during a solar eclipse. Use special glasses with eclipse filters, as regular sunglasses won't offer sufficient protection. Prioritize your eye health while enjoying the beautiful spectacle of a solar eclipse.

NASA's SpaceX Crew-10 mission is scheduled to launch tomorrow, March 12, from Kennedy Space Center in Florida. SpaceX's Crew Dragon spacecraft will lift off atop a Falcon 9 rocket and is expected to dock to the International Space Station (ISS) the following day. Crew Dragon will carry NASA astronauts Anne McClain as commander and Nichole Ayers as pilot, along with Japan Aerospace Exploration Agency astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov to the ISS for an approximate five-month science mission. The crewed vessel will also deliver materials for Canadian experiments Vascular Calcium and Space Health, which includes headbands and wearables for the Bio-Monitor, a Canadian innovative all-in-one wearable technology designed to fit into an astronaut's daily routine and measure physiological data.

CSA astronauts Jeremy Hansen and Jenni Gibbons, along with the rest of their Artemis II crewmates, had the chance to view segments of the SLS rocket, as well as the Orion capsule that will take the prime crew around the Moon. Jeremy shares his excitement live from the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida.

A Canadian photon detector module that was designed, assembled, and programmed at the University of Waterloo recently launched to the ISS on NASA's SpaceX CRS-31 commercial resupply mission.

WildFireSat is the first government-owned satellite mission set to monitor all active wildfires across Canada on a daily basis. This Canadian mission will consist of a constellation of seven microsatellites that will provide timely, essential data to track fire activity and support fire management efforts.

Since its inception in November 2000, the Charter has played a crucial role in coordinating global satellite resources to support emergency responses. It provides free, rapid access to satellite imagery to support rescue and emergency responders around the world and has repeatedly shown the power of international collaboration in addressing natural and man-made disasters. As of January 30, 2025, 943 disasters have been imaged by contributing satellites in 136 countries worldwide.

In November 2024, as part of the CRS-31 mission, flight controllers remotely manoeuvred Canadarm2 and Dextre to extract a payload from the SpaceX Dragon cargo ship's trunk (CRS-31) and install it on the International Space Station. This animation was developed in preparation for the operation and shows just how complex robotic tasks can be.

Following an announcement of opportunity published in August 2022, the CSA recently awarded over $1.4 million in contribution to QEYnet (Maple, Ontario) for the demonstration of a low-cost, Earth-to-space quantum key distribution (QKD) technology. QEYnet is developing a solution to address these issues by using QKD, which leverages the quantum properties of individual light energy particles, also known as photons, to generate encryption keys that are mathematically guaranteed to resist undetected eavesdropping.

CSA astronaut Joshua Kutryk talks about his passion for flying, which began in his childhood. He tells the story of two brothers who dreamed of flying together and built cardboard airplanes while waiting to realize their dream.
