Manufacturer. Boeing, United Launch Alliance, Orbital ATK, Aerojet Rocketdyne. Country of origin. United States. Project cost. US$7 billion (2. 01. It follows the cancellation of the Constellation program, and is to replace the retired Space Shuttle. The NASA Authorization Act of 2. Constellation program's Ares I and Ares V vehicle designs into a single launch vehicle usable for both crew and cargo, similar to the Ares IV.
The SLS will have 2. Saturn V and a comparable payload capacity, putting the SLS into the super heavy- lift launch vehicle class of rockets. Its initial Block 1 version is to lift a payload of 7. Earth orbit (LEO), which will be increased with the debut of Block 1. B and the Exploration Upper Stage. The SLS will launch the Orion Crew and Service Module and may support trips to the International Space Station if necessary. SLS will use the ground operations and launch facilities at NASA's Kennedy Space Center, Florida.
During the joint Senate- NASA presentation in September 2. SLS program has a projected development cost of $1. SLS rocket, $6 billion for the Orion Multi- Purpose Crew Vehicle and $2 billion for upgrades to the launch pad and other facilities at Kennedy Space Center. Each will use the same core stage with four main engines, but Block 1. B will feature a more powerful second stage called the Exploration Upper Stage (EUS), and Block 2 will combine the EUS with upgraded boosters.
Block 1 has a baseline LEO payload capacity of 7. Block 1. B has a baseline of 1. The proposed Block 2 will have lift capacity of 1. Saturn V. The review encompassed all aspects of the SLS' design, not only the rocket and boosters but also ground support and logistical arrangements. Initial planning included studies of a smaller Block 0 configuration with three RS- 2. Modifications for the SLS included the addition of a center booster segment, new avionics, and new insulation which eliminates the Shuttle SRB's asbestos and is 8. The five- segment SRBs provide approximately 2.
Shuttle SRB and will not be recovered after use. These include successful firings of three developmental motors (DM- 1 to DM- 3) from 2. The DM- 2 motor was cooled to a core temperature of 4. It was the final ground test before Exploration Mission 1 (EM- 1). Early plans would have developed advanced boosters before an updated second stage; this configuration was called Block 1.
A. By 2. 01. 2 NASA planned to select these new boosters through an Advanced Booster Competition which was to be held in 2. Each AJ1. E6 engine would produce 4,9. N (1,1. 00,0. 00 lbf) thrust using a single turbopump to supply dual combustion chambers.
This booster would switch from a steel case to one made of lighter composite material, use a more energetic propellant, and reduce the number of segments from five to four. According to ATK, the advanced booster would be 4. Shuttle- derived five- segment SRB. It is uncertain if the booster will allow SLS to deliver the mandated 1. LEO without the addition of a fifth engine to the core stage. The F- 1. B would be derived from the F- 1 engine, which powered the first stage of the Saturn V.
It would have been easier to assemble, with fewer parts and a simplified design. The oxygen- rich staged combustion cycle . The Russians have been flying ox. This stage will be a modified Delta IV 5.
Block 1 will be capable of lifting 7. ICPS will be considered part of the payload and be placed into an initial 1,8. ICPS will perform an orbital insertion burn at apogee, and then a translunar injection burn to send the uncrewed Orion on a circumlunar excursion. It is expected to be used by Block 1. B and Block 2 and, like the core stage, have a diameter of 8.
The EUS is to be powered by four RL1. Cold launched, it would be assembled in- orbit by a number of Block 2 SLS payload lifts.
The Orion crew capsule is docked on the right. The Earth Departure Stage, powered by J- 2. X engines. The shorter flight duration, estimated at 3. The analysis was based on a second stage usable propellant load of 1. Block 1 and ICPS, which will carry 2.
The ICPS upper stage and upper stages using four RL1. MB6. 0 engines and one J- 2. X engine were studied. The Vinci offers the same specific impulse but with 6. The assembled rocket is to be able to remain at the launch pad for a minimum of 1.
Tests continued throughout Spring of 2. A second round of similar tests are planned for 2. Orbital ATK began casting propellant for the solid rocket boosters and manufacturing parts for the boosters in 2. The company test fired a solid rocket booster in early 2. Once completed the test articles will be sent to ensure structural integrity at Marshall Spaceflight Center.
The ICPS for EM- 1 was slated for assembly in late January, and a structural test article was delivered to NASA in 2. This is equivalent to $8. NASA New Start Inflation Indices. The SLS program has a 7. Associate Administrator for NASA, Robert Lightfoot. Representative. Dana Rohrabacher and others added that instead, a propellant depot should be developed and the Commercial Crew Development program accelerated.
Zubrin also disagrees with those that say the U. S. Tom Mc. Clintock and other groups argue that the Congressional mandates forcing NASA to use Space Shuttle components for SLS amounts to a de facto non- competitive, single source requirement assuring contracts to existing shuttle suppliers, and calling the Government Accountability Office (GAO) to investigate possible violations of the Competition in Contracting Act (CICA). Wilhite of Georgia Tech presented a study earlier this year estimating that depot tanks would lose about $1. Earth orbit if protected only with passive insulation. The Wall Street Journal.
