In the months that followed NASA’s Double Asteroid Redirection Test (DART) mission, which sent a spacecraft to intentionally collide with an asteroid moonlet, the science team verified that kinetic impact was a viable deflection technique, proving one effective method of preventing future asteroid strikes on Earth.Since then, researchers have continued studying data collected from the successful experiment, focusing specifically on surface features of the binary asteroid system, composed of moonlet Dimorphos and parent asteroid Didymos.

When the Danish bulk carrier Nordic Orion set sail on Sept. 17, 2013, from Vancouver, British Columbia, on a journey to Finland, it set a course for a groundbreaking journey. Rather than turn south to pass through the Panama Canal, it headed north to traverse the Northwest Passage, a winding sea route through the archipelago off Canada’s north and east coasts.

In February 2016, 215 soldiers from the U.S. and Canadian militaries conducted a 10-day exercise called Arctic Ram. Their objective was to demonstrate they could rapidly respond to an emergency in the Arctic. In this case, they simulated retrieving a military satellite that crash-landed north of the small town of Resolute on Cornwallis Island in Nunavut, Canada.

Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have established new, scalable methods of developing battery- and solar-powered fibers, making it theoretically possible for electrical energy to be harvested from, and stored in, the clothing people wear. These fibers could power high-performance wearable electronics that breathe, stretch and wash just like conventional textiles.

Fueled by increasing temperatures and droughts, severe wildfires are on the rise around the world — as are the smoke-borne contaminants that harm the environment and human health. In 2023, Canada recorded its worst wildfire season ever, with fires releasing more than 290 million tons of carbon into the atmosphere. California also experienced record-setting fire seasons in 2020 and 2021.

Johns Hopkins Applied Physics Laboratory (APL) researchers have developed one of the world’s smallest, most intense and fastest refrigeration devices, the wearable thin-film thermoelectric cooler (TFTEC), and teamed with neuroscientists to help amputees perceive a sense of temperature with their phantom limbs. This advancement, one of the first of its kind, enables a useful new capability for a variety of applications, including improved prostheses, haptics for new modalities in augmented reality (AR) and thermally modulated therapeutics for applications such as pain management.
