Starship has more than twice as much thrust as SLS. Super heavy produces 17 million lbs at launch, and the spacecraft, about 3 million.NASA's SLS blasts off with four heavy duty engines out for one last ride. But SpaceX's Heavy Booster will lift from the pad using 33 engines firing at once. They're lower powered and designed to be nimble, versatile and operable across projects.NASA is going back to the moon and it has the rocket to do it — the SLS. Meanwhile, Elon Musk and SpaceX are hard at work on their own giant Starship rocket, meant to one day bring humans to Mars.

Will Artemis use SLS or Starship : The Artemis 3 mission to the lunar surface depends on a variant of SpaceX's Starship launch vehicle adapted for landing.

Is Starship more powerful than SLS

Starship is a reusable rocket larger and far more powerful than NASA's Artemis Special Launch System and one that could take humans to the moon and Mars.

Why is NASA still using SLS : SLS is part of NASA's backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon and commercial human landing systems, next-generation spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA is worried that SpaceX's giant new Starship vehicle won't be ready to carry astronauts to the surface of the moon in late 2025, as currently planned.

SLS and Artemis are out of control cost-plus projects. No matter how much money is wasted or how many years of delay there are the companies get to re-bill all expenses and get more profit for more waste.

Is NASA paying for Starship

NASA is already funding Starship, the largest rocket in history, to the tune of billions of dollars to ferry astronauts to the lunar surface—but Starship also has the potential to launch immense payloads off other worlds and back to Earth.Starship is a reusable rocket larger and far more powerful than NASA's Artemis Special Launch System and one that could take humans to the moon and Mars.NASA is aware of the cost concerns with SLS. “Senior agency officials have told us that at current cost levels the SLS program is unsustainable and exceeds what NASA officials believe will be available for its Artemis missions,” the GAO report stated, which also used the term “unaffordable.”

The crew of Artemis III will ride to lunar orbit aboard the Orion spacecraft, where Orion will dock with the Starship human landing system in preparation for their journey to the lunar surface. Orion is the only spacecraft capable of returning crews to Earth at lunar reentry velocities.

Will NASA use Starship for Artemis : For the Artemis III mission, astronauts will ride the Orion spacecraft from Earth to lunar orbit, and then once the two spacecraft are docked, move to the lander, the Starship Human Landing System (HLS) that will bring them to the surface.

Is NASA SLS too expensive : In an Oct. 12 report, NASA's Office of Inspector General (OIG) concluded a 50% reduction in SLS launch costs projected by NASA by moving to a services contract is “highly unrealistic,” with the vehicle's cost likely to remain above $2 billion for the foreseeable future.

Will Artemis 3 use SLS or Starship

The crew of four astronauts will launch on the Block 1 configuration of the Space Launch System (SLS) rocket from NASA's Kennedy Space Center in Florida . SLS is the only rocket capable of launching crew to the Moon aboard Orion.

NASA is worried that SpaceX's giant new Starship vehicle won't be ready to carry astronauts to the surface of the moon in late 2025, as currently planned.As part of NASA's Artemis campaign to return humans to the Moon for the benefit of all, the agency is working with SpaceX to develop the company's Starship human landing system (HLS), which will land astronauts near the Moon's South Pole during the Artemis III and Artemis IV missions.

Why is SpaceX so much cheaper than NASA : SpaceX is 10X cheaper with 30X lower cost overrun than NASA in lifting payload into space. Why Because SpaceX is platform-based, NASA not. “The space race is dominated by new contenders,” claims The Economist (18 October 2018).
