SiriusXM-7 (SXM-7) is a high power digital audio broadcast satellite for Sirius XM's internet and satellite radio services.

It will be the 11th overall satellite of the Sirius and XM network, though only five satellites are currently operational (two XM, two Sirius, and one spare).

SXM-7 will be the first combined SiriusXM platform, capable of delivering either service.

It will replace the XM-3 satellite which was launched in 2005 and has been operational for 15 years.

Maxar built SXM-7 along with SXM-8 -- a twin.

Both satellites are designed for 15 years of operations once in geostationary orbit of Earth.

Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond.

Falcon 9 is the world’s first orbital-class reusable rocket.

On January 24, 2021, Falcon 9 launched the first ride-share mission to Sun Synchronous Orbit. It was delivering a record-setting 143 satellites to space. And while this was an important mission for SpaceX in itself, it was also the moment Falcon 9 overtook United Launch Alliance’s Atlas V for the total number of consecutive successful launches.

SpaceX’s Falcon 9 had become America’s workhorse rocket, launching 31 times in 2021. It has already beaten that record this year, launching almost an average of once a week. While most of the launches deliver Starlink satellites to orbit, the company is still launching the most commercial payloads to orbit, too.

Falcon 9 is a medium-lift launch vehicle, with the capability to launch over 22.8 metric tonnes to low earth orbit. Unlike any other rocket, its first stage lands back on Earth after separating from its second stage. In part, this allows SpaceX to offer the cheapest option for most customers with payloads that need to reach orbit.

Under its ride-share program, a kilogram can be placed in a sun-synchronous orbit for a mere 1.1 million dollars, far cheaper than all other currently operating small satellite launch vehicles.

The reusability and fast booster turnaround times have made Falcon 9 the preferred choice for private companies and government agencies. This has allowed SpaceX to capture a huge portion of the launch market.

Space Launch Complex 40 (SLC-40) is one of two launch sites leased by SpaceX at Cape Canaveral Space Force Station (CCSFS) in Florida, specifically designed for preparing and launching Falcon 9 rockets. Constructed in the early 1960s, SLC-40 was initially used for 55 Titan III and Titan IV rocket launches, including the Cassini-Huygens mission to Saturn. The pad was active from June 18, 1965, to April 30, 2005.

SpaceX began leasing SLC-40 in 2007, converting it to support Falcon 9 rockets. The pad was first upgraded to accommodate the original version of Falcon 9 and later received another upgrade in 2013 to handle the larger, reusable Falcon 9 rocket. On September 1, 2016, an explosion during a Falcon 9 fueling test caused severe damage to the pad. It was rebuilt rapidly, with construction completed in just 10 months, from mid-February to late November 2017. SLC-40 resumed operations with the successful launch of a Dragon capsule to the International Space Station on December 15, 2017.

After adding a crew access arm to the launch tower, SpaceX launched their first crewed mission from SLC-40 on Saturday, September 28th 2024 for NASA's Crew-9 mission to the International Space Station.

Under SpaceX’s management, SLC-40 has been the site of numerous significant missions. Notable launches include the first all-commercial Dragon mission to the International Space Station, NASA’s DSCOVR mission, the Transiting Exoplanet Survey Satellite (TESS) for NASA and MIT, the first satellite for Turkmenistan, the classified Zuma mission for Northrop Grumman and the U.S. government, the first GPS-III satellite, and the Beresheet lunar lander for Israel. Additionally, in September 2024, SLC-40 will host its first crewed launch with SpaceX’s Crew-9 mission, marking a new milestone for the pad.

Cape Canaveral is a major launch site with four currently active launch pads for Atlas V, Delta IV Heavy, Falcon 9, and Minotaur rockets. Located on Florida’s east coast, it offers extensive access to space for a variety of missions, including those targeting the Space Station, Geostationary Earth Orbit, the Moon, interplanetary destinations, and polar trajectories. The site’s location ensures that launches occur over the open Atlantic Ocean, minimizing risks to populated areas.

Cape Canaveral is often confused with or referred to alongside NASA’s Kennedy Space Center on Merritt Island. While they are separate installations, both play pivotal roles in the U.S. space program. Cape Canaveral has a storied history of significant space missions, including the launch of the first U.S. Earth satellite, Explorer 1, in 1958; the first U.S. astronaut, Alan Shepard, in 1961; the first U.S. astronaut in orbit, John Glenn, in 1962; the launch of the first two-person U.S. spacecraft, Gemini 3, in 1965; and the first U.S. uncrewed lunar landing mission, Surveyor 1, in 1966.

SLC-40 and Cape Canaveral continue to be integral to SpaceX’s ambitious launch schedule and the broader U.S. space program, supporting a wide range of missions and contributing to advancements in space exploration.

The Autonomous Spaceport Drone Ship "Just Read The Instructions" (JRTI) is one of two recovery ships stationed in the Atlantic Ocean for SpaceX's Falcon 9 rockets. The original version of JRTI operated in the Pacific Ocean, supporting launches from Vandenberg Space Force Base in California. It was later upgraded and relocated to the East Coast, primarily operating out of Port Canaveral, Florida. Its first Atlantic Ocean mission was in June 2020, supporting the 8th Starlink launch.

JRTI is an autonomous vessel serving as a mobile landing platform, crucial to SpaceX's efforts to recover and reuse rocket components, which significantly reduces spaceflight costs. The ship's name, "Just Read The Instructions," is inspired by a spacecraft in Iain M. Banks' *Culture* series, known for its whimsical and thought-provoking names.

Equipped with a large landing platform and advanced navigation systems, JRTI uses thrusters to maintain precise positioning, even in rough seas. It works in tandem with the other SpaceX drone ship, "A Shortfall of Gravitas" (ASOG), both of which have been instrumental in SpaceX's success in landing and reusing rocket boosters.
