Start Falcona 9 z trzema satelitami konstelacji RADARSAT - 12.06.2019 / Credits - SpaceXRakieta Falcon 9 wyniosła 12 czerwca trzy kanadyjskie satelity RADARSAT.
Start rakiety Falcon 9 z trzema satelitami RADARSAT nastąpił 12 czerwca 2019 roku o godzinie 16:17 CEST. Start nastąpił z bazy Vandengerg w Kalifornii. Na pokładzie rakiety Falcon 9 znalazły się trzy kanadyjskie satelity RADARSAT. Rakieta Falcon 9 wyniosła te satelity na orbitę polarną, gdzie nastąpiło uwolnienie około godzinę po starcie.

Po wykonanej pracy nastąpiło lądowanie pierwszego stopnia rakiety Falcon 9. Tym razem lądowanie nastąpiło w “Landing Zone – 4”, czyli lądowisku nieopodal wyrzutni w bazie Vandenberg. Zarówno start jak i lądowanie nastąpiło w gęstej mgle, ale pomimo tego przebiegło perfekcyjnie.
Satelity konstelacji RADARSAT to kontynuacja kanadyjskich doświadczeń w satelitarnych obserwacjach radowych. Pierwszy satelita RADARSAT został wyniesiony na orbitę w 1995 roku, zaś drugi w 2007 roku. Tym razem w jednym starcie zostały wyniesione trzy satelity, które wspólnie będą wykonywać obserwacje Ziemi. Satelity będą operować z orbity polarnej o wysokości 600 km.

The first stage that launched Wednesday previously flew on a mission from Florida on March 2 to loft SpaceX’s Crew Dragon capsule on its first unpiloted test flight to the International Space Station.
(...) The satellites will extend their flat panel radar antennas, each with an area of about 100 square feet (9.5 square meters), within the first couple of days of the mission, according to MDA, the prime contractor for the Radarsat Constellation Mission. The radars will be powered on for the first time 10 or 11 days after launch, MDA officials said, to begin functional checks and take the first test images.
The full commissioning and calibration campaign will take three to six months, then the Canadian Space Agency will declare the RCM satellites operational and ready for regular observations, officials said.
More than 125 Canadian companies from seven provinces helped develop and build the three new Radarsat satellites. Canada’s new fleet of Earth-observing spacecraft follows Radarsat 1 and Radarsat 2 — launched in 1995 and 2007 — and are designed to continue operations of the country’s flagship satellite system through at least 2026.
“It’s extremely important for Canada,” said Mike Greenley, group president of MDA, in a pre-launch interview with Spaceflight Now.
The RCM project is costing the Canadian government roughly $900 million (1.2 billion Canadian dollars), including the development of the satellites, the launch, and seven years of planned operations, according to Steve Iris, the RSM mission manager at the Canadian Space Agency.
That makes RCM one of the most costly Canadian-led space missions in history, and one of the most expensive payloads ever launched by SpaceX.
Each RCM satellite carries a C-band radar instrument, with a deployable antenna array, transmitters and receivers.
Unlike optical cameras, radars can see through clouds and make observations day and night. The radar instruments emit signals and measure the waves reflected off Earth’s surface, yielding information about structures, ships, forests, ice, and crops.
“Earth observation is critical, and radar-based Earth observation gives Canada excellent capabiltiy to deal with the sovereignty and security of Canadians,” Greenley said.
A dozen Canadian government agencies, including the military, use Radarsat data. That broad use is expected continue with RCM.

Laporte said the Canadian Space Agency has already started planning the next generation of Radarsat for when RCM reaches its planned end of life in 2026. How Radarsat data will be controlled could change again with that generation, he said.
“I’ve tasked them to be creative with respect to the business model,” Laporte said. “It doesn’t have to be a repeat of what we’ve done already. We could try something different, and who knows where that is going to take us.” (...)
