Radarsat-2 was launched in 2007 and is still operational, but the new three-satellite constellation is created to greatly increase coverage, according to the space agency.

Three Canadian satellites representing the next generation of Earth-observation technology have been successfully deployed after being launched into orbit today aboard a SpaceX rocket.

Falcon 9's first stage for this mission previously supported Crew Dragon's first demonstration mission in March 2019. The reusable first stage booster could be seen separating from the payload and began its return to land back at the launch pad.

After several months of delays and rescheduling, SpaceX is expected to launch its Falcon 9 rocket from Vandenberg Air Force Base at 7:17 a.m. Wednesday. After starting the first stage of Falcon 9 made a successful landing back to Earth.

Sonic booms may wake up people along the coasts in Ventura and Santa Barbara counties when SpaceX attempts to land a rocket that will carry three satellites Wednesday morning from Vandenberg Air Force Base. Each of the 1.4-tonne satellites were successively launched into orbit after 54 minutes after launch.

"In addition to our resource-based economy requiring monitoring of our forests, mining, energy, and agricultural industries, our northern latitudes that are sensitive to climate change gain from space-based radar systems that can observe the Earth day and night in any weather conditions", she said. RADARSAT-1 which was in operation for over 17 years, from 1995 to 2013, regularly scanned at a resolution of 100 m, and managed 10 metre resolution, at best, for its fine-scale focused imagery. According to Canada's Space Agency, they will be used to gather data for a variety of purposes, including maritime surveillance, disaster management, and ecosystem monitoring. RADARSAT-2 went up in 2007 and remains active.

"The RCM has the capacity to image any given location on 90 percent of the Earth's surface daily, but will be primarily imaging Canadian territory".
