The rocket can carry 5,500 kg (12,100 lb) to GTO when the first stage is recovered. If fully used, it can carry 8,300 kg (18,300 lb) to geostationary transfer orbit (GTO). Space Launch Complex-41 (SLC-41) will be the first dual-use 18 Falcon 9 can carry of up to 22,800 kilograms (50,300 lb) to low Earth orbit (LEO). ULA has been heavily investing in modifying our factory in Decatur, Alabama, and modernize our infrastructure at the launch facilities in Cape Canaveral, Florida, to support Vulcan rockets. Finally, for small satellites exceeding the mass of an ESPA capability, the Multi-Payload Canister System is a load-bearing separating canister that can be utilized to enclose an aft small satellite while supporting a forward traditional large satellite. The Secondary Payload Adapter (ESPA Ring) is located between the upper stage and the primary payload and can accommodate 4-6 payload modules weighing up to 318 kg each. The Aft Bulkhead Carrier (ABC) interfaces at the aft end of the Centaur upper stage and can carry up to 24U CubeSats weighing 80 kg each. Multi-Manifest on a Vulcan rocket provides a highly reliable and schedule certain launch solution for spacecraft ranging from CubeSats to small sats and beyond.ĭependent on the size of the spacecraft, multi-manifesting on a Vulcan can be done in several ways. With multi-manifest, two or more spacecraft are integrated on a launch vehicle using available performance and volume margin that would otherwise go unused - optimizing mass to orbit and enabling missions. However, ULA provides flexible and cost-effective multi-manifest solutions to overcome this barrier. The payload fairing is available in the 15.5-m (51-ft) standard and 21.3-m (70-ft) long configurations.Īccess to orbit remains a critical hurdle for many missions. The PLF separates using a debris-free horizontal and vertical separation system with spring packs andįrangible joint assembly. The payloadĪttach fitting (PAF) is a similar sandwich composite structure creating the mating interface from spacecraft to second stage and payload fairing. The bisector (two-piece shell) PLF encapsulates the spacecraft. All ULA PLFs are configured for off-pad payload encapsulation to enhance payload safety and security and minimize on-pad time.Įncapsulated in a 5.4-m- (17.7-ft-) diameter payload fairing (PLF), a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The payload fairing (PLF) provides a controlled, safe environment for spacecraft during ascent.

In February 2010, SpaceXs first flight stack was set up at Space Launch Complex 40. SpaceX scheduled launch date of March 2010. (329 seconds) firing of the Falcon 9 second stage was held. Its name comes from the fictional Star Wars spacecraft, the. You do not want your rocket stage to blow up, as it creates an uncontrolable swarm of debris and includes the risk that particles are ejected into orbits where they do not decay quickly, adding to the space debris risk.Īs for burning up, it's a bit of both. They use cryogenic liquid oxygen and rocket-grade kerosene as fuel. > Depressurization and fuel venting avoids the risk of the rocket stage blowing up, for example as a result of static electricity building up in the rocket stage. Once its work is done, this excess fuel is often vented, also known as "depressurization". The booster would utilize multiple Raptor engines, similar to the use of nine Merlin 1s on each Falcon 9 booster core. So it always has a sufficient fuel margin. > Rocket stages always carry excess fuel, as you don't want the engine to cut out prematurely by running out of fuel. ![]() The fuel dump is to prevent explosions before reentry that could damage the spacecraft it just delivered or create unnecessary space debris. ![]()
