Can a solid rocket booster be throttled?

Controllable solid rocket motors combine the sim- plicity of solid rockets and the thrust variation ability of the liquid and hybrid engines. ESP Propellant: ESPs are safe and volumetrically- efficient solid motors that can be throttled, extin- guished, and re-ignited like liquid propulsion systems.

What happens to the solid rocket boosters after separation?

At an altitude of approximately 45 km (24 nautical miles), the boosters separate from the orbiter/external tank, descend on parachutes, and land in the Atlantic Ocean (+ View Video: SRB Processing). They are recovered by ships, returned to land, and refurbished for reuse.

What is the SLS rocket used for?

SLS has the power to send payloads with more mass and volume to deep space than any rocket ever built. This makes it possible to send astronauts to distant destinations including Mars. The SLS booster is the largest, most powerful solid propellant booster ever built for flight.

What is the Space Launch System (SLS)?

The first SLS vehicle, called Block 1, can send more than 27 metric tons (t) or 59,500 pounds (lbs.) to orbits beyond the Moon. It will be powered by twin five-segment solid rocket boosters and four RS-25 liquid propellant engines. After reaching space, the Interim Cryogenic Propulsion Stage (ICPS) sends Orion on to the Moon.

How many boosters are needed to power SLS?

Two shuttle-derived solid rocket boosters will power the initial flights of the SLS. To provide the additional power needed for the rocket, the prime contractor for the boosters, Northrop Grumman, of Redondo Beach, California, has modified the original shuttle’s configura- tion of four propellant segments to a five-segment version.

What is the size of SLS Block 1 rocket?

Artemis I, the first integrated flight of SLS and Orion, uses the Block 1 configuration, which stands 322 feet, taller than the Statue of Liberty, and weighs 5.75 million lbs. SLS will produce 8.8 million lbs. of maximum thrust, 15 percent more thrust than the Saturn V rocket.
