ЦитатаFor immediate release: October 16, 2018Maxar Technologies' MDA Ships Third and Final Spacecraft in Preparation for Launch of the RADARSAT Constellation MissionRichmond, BC - MDA, a Maxar Technologies company (NYSE: MAXR) (TSX: MAXR), announced that it has shipped, as planned, the third and final satellite for the RADARSAT Constellation Mission (RCM) that MDA is building for the Canadian Space Agency. The constellation will launch from the Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket. RCM is the evolution of the highly successful RADARSAT Program that MDA has been an integral part of since the early 1990's. The three-satellite constellation will ensure data continuity and improve operational use of Synthetic Aperture Radar (SAR) and system reliability. RCM will provide daily revisits of Canada's vast territory and maritime approaches, as well as daily access to 90% of the world's surface. "Finalizing these satellites is a monumental achievement for MDA and its extensive cross-Canada industrial supply chain whose Canadian employees have worked extremely hard for many years on this program," said Mike Greenley, group president of MDA. "The program has been on budget and schedule since award of the build phase contract in 2013, which is a remarkable achievement for a program this complex. We are looking forward to Canada creating, funding and implementing a long-term space plan that sustains and grows Canada's global leadership position in space-based radar Earth observation." RCM consists of three space-based radar satellites that can see through clouds and darkness to provide data on Canada's vast land mass and coastal approaches. Information from RCM is used for many different applications that are of benefit to Canadians and to the entire world population. These applications include monitoring of glaciers and other changes on the planet, which, in turn, are used to measure global climate change and help scientists to better understand humankind's impact on our environment. RCM data will also be used to monitor agricultural regions, which is then used to improve the efficiency of agricultural growing operations and ultimately the world food supply; and to monitor natural resources such as forests and other ecosystems enabling better management of those environmentally critical regions. For maritime surveillance, radar satellite systems are the preferred choice for marine and coastal areas with cloudy and foggy weather conditions, allowing for enhanced monitoring of oil spills. Being able to predict the direction oil spills will take and their drift by using a map of marine wind directions derived from radar images will be very helpful to environmental protection organizations. The RCM satellite constellation is expected to operate for at least seven years providing benefits beyond our imagination both for Canadians and for the entire world. The launch of the constellation is scheduled for the week of February 18, 2019, based on launch vehicle availability.
ЦитатаRADARSAT Constellation: A major milestone reachedThe third and final RCM spacecraft leaving MDA's Montreal facilities on September 24, 2018. (Credit: CSA.)After building and testing the RADARSAT Constellation Mission (RCM) for more than five years, MDA, the Prime Contractor for the RCM, safely delivered the third and final spacecraft to its California-based sister company SSL on September 30, 2018, in preparation for launch.As you can imagine, transporting satellites over such long distances between two countries is no easy task. It requires lots of paperwork and intricate logistics. The process begins well before each spacecraft is packed and loaded onto the truck, which is a two-day affair. A customs officer even needs to be present when the container is being closed and sealed with anti-tampering devices.Congratulations to the joint CSA-MDA team for achieving this important milestone! We would also like to thank the 125 suppliers across Canada and others across the globe who played a part in the RCM project.ЦитатаDeparture: MDA facilities, Sainte-Anne-de-Bellevue, QuebecDestination: SSL, Palo Alto, CaliforniaDistance travelled: 4905 kmTravel time: 7 daysLaunch window: Week of February 18, 2019Vehicle: SpaceX Falcon 9 rocketMembers of the MDA-CSA team who worked on the RCM pose in front of the container that houses the third spacecraft before it left the Montreal area on September 24, 2018.

ЦитатаSpaceX Falcon 9 and $1B satellite trio set for first California launch in monthsFALCON 9 B1051 WILL BE THE FIRST BLOCK 5 BOOSTER TO FLY AGAIN AFTER A LOW-ENERGY LOW EARTH ORBIT (LEO) RECOVERY. (PAULINE ACALIN) By Eric RalphPosted on June 5, 2019After the better part of both half a year of launch delays and launch pad inactivity, SpaceX and Falcon 9 are ready to return the company's California-based SLC-4 facilities to action with the launch of the $1 billion Radarsat Constellation Mission (RCM).Built by Maxar for the Canadian Space Agency (CSA), RCM is a trio of remote-sensing spacecraft designed with large surface-scanning radars as their primary payload. Having suffered years of technical delays during Maxar's production process, RCM was initially available for launch as early as November 2018. In an unlucky turn of events, issues on the SpaceX side of things took RCM's assigned Falcon 9 booster out of commission and lead to an additional seven or so months of launch delays. At long last, RCM is just one week away from heading to orbit, scheduled to launch from Vandenberg Air Force Base (VAFB) no earlier than 7:17 am PDT (14:17 UTC), June 11th.THE GOLDILOCKS BOOSTEROnce the three RCM satellites were effectively complete, a series of unfortunate circumstances combined to delay the constellation's launch almost indefinitely. The first domino fell in December 2018, when Falcon 9 Block 5 booster B1050 - having successfully supported Cargo Dragon's CRS-16 launch - suffered a failure that prevented a successful landing. Incredibly, the booster did survive its accidental Atlantic Ocean landing and is now sitting in a SpaceX hangar, but B1051 is unlikely to ever fly again. This posed a problem for Maxar and the Canadian Space Agency (CSA), who seem to have contractually requested that RCM launch on either a new or very gently flight-proven Falcon 9 booster. The problem: SpaceX had none of either option available for RCM after B1050's unplanned swim and needed to balance the needs of several other important customers. Several Block 5 boosters were technically available but all had two or even three previous launches under their belts.Falcon 9 B1046 completed SpaceX's first triple-reuse of a booster just days after B1050's failed landing. (Pauline Acalin)Meanwhile, SpaceX's booster production had been almost entirely focused (and would remain so months after) on building four new Falcon Heavy boosters and the first expendable Falcon 9 Block 5 booster, reserved for the US Air Force and a long-delayed customer. Since those five boosters were completed and shipped out, just one additional booster (B1056) has been finished, launching Cargo Dragon's CRS-17 mission just one month ago. In short, had Maxar/CSA waited for a new booster, RCM's launch would likely be delayed at least another 30-60 days beyond its current target of June 11th. Instead, they downselected to Falcon 9 B1051, then in the midst of several months of prelaunch preparations for Crew Dragon's launch debut (DM-1). DM-1 went off without a hitch in early March, after which the gently-used B1051 underwent a brisk ~45 days of inspection and refurbishment before heading west to SpaceX's VAFB launch pad.Falcon 9 B1051 was spotted by Jean-Michel Levesque traveling through Northern California on May 1st. (Twitter - Jean-Michel Levesque)BILLION DOLLAR BABIES Скрытый текст: From an external perspective, forgoing a twice or thrice-flown Falcon 9 Block 5 booster after nearly a dozen successful demonstrations does not exactly appear to be a rational decision. However, whether it was motivated by conservatism, risk-aversion, or something else, Maxar and CSA likely have every contractual right to demand certain conditions, as long as they accept the consequences of those requirements. In the case of RCM, the customers accepted what they likely knew would be months of guaranteed delays to minimize something they perceived as a risk. To some extent, it's hard to blame them. After going more than $400M over budget, the Maxar-built trio of upgraded Radarsat satellites are expected to end up costing more than $1 billion. CSA's annual budget typically stands around $250M, meaning that this single launch is equivalent to four years of space agency's entire budget. A failed launch would be a huge setback. Additionally, RCM will likely become the most valuable payload ever launched by SpaceX, beating out the Air Force's ~$600M GPS III SV01 spacecraft by a huge margin. For RCM, mission assurance is definitively second to none.SpaceX's Vandenberg landing zone - deemed LZ-4 - is less than 1500 feet (500 meters) away from its SLC-4E launch pad. (SpaceX)SpaceX christened its LZ-4 West Coast landing zone in October 2018. (Pauline Acalin)If all goes as planned, Falcon 9's RCM launch should also mark the second use of SpaceX's West Coast landing zone (LZ-4), christened during the October 2018 launch of SAOCOM 1A - coincidentally, also a radar-carrying Earth observation satellite. This means that press photographers (including Teslarati's Pauline Acalin and Tom Cross) will have their second chance ever to capture remote images of a SpaceX booster landing.
