On Friday, Dec. 11, at 12:55 PM EST the Falcon 9 rocket carrying the satellite for SiriusXM got delayed and was stopped 1 minute before the launch. It was stopped because it needed a recheck in the ground systems. Check the full video of the event in the video below.
It was stated in a tweet from SpaceX that the launch would resume on 13th December, Sunday.
On Sunday, December 13th at 12:30 pm EST Falcon9 launched the Sirius XM-7 from the Space Launch Complex 40 finally as mentioned in the tweet by Space X.
Why SXM-7 is considered a massive geostationary satellite ?
It is described as one of the satellites to replace the XM-3 and XM-4 which were set up in 2005 and 2006 as mentioned in maxar.com. It weighs around 7,000 kg (roughly 15,432 Ibs) and so it is considered as one of the massive geostationary satellite.
SiriusXM is the property owner of the SXM-7. The MAXAR technologies constructed the structure. Bridget Neville vice president at SiriusXM said “We are pleased to once again collaborate with SSL on two advanced satellites that will bolster service to our subscribers for years to come. SSL is a premier designer and manufacturer of reliable communications satellites, with the technological capability to meet our demanding requirements. We look forward to working together on the new satellites.”
Both the SXM-7 and SXM-8 are based on the powerful SSL 1300 platform which can support a long-range of applications with advanced technologies ahead. It is estimated to provide service for about 15 years. Check the countdown, launch, landing, and deployment time of the SXM-7 mission noted on the official site of SpaceX. The most important feature of this satellite is that it will help facilitate radios on earth to connect without any dish antenna. Both the SXM-7 and SXM-8 satellite has solar panels that are capable of generating up to 20 kilowatts of power as mentioned in NASA spaceflight.
According to the SpaceX the mission was achieved with the help of Falcon 9 first-stage rocket booster. After that Falcon 9 was finally landed by SpaceX on the “Just Read the Instructions” droneship, established in the Atlantic ocean.
