NASA just announced the lunar landers for the Artemis program and to everyone’s surprise, SpaceX’s MASSIVE Starship is actually one of the landers NASA chose alongside Blue Origin and Dynetics. And this is bringing up a lot of questions, some of which we’ll answer in my next video, “Should NASA just cancel SLS and use Starship and / or other commercial launchers for Artemis?”. But today I think we need to settle a lot of debates here first about these two rockets and now more than ever, it’s time we truly pit them head to head.

NASA’s powerful Space Launch System rocket and NASA’s Orion spacecraft are making progress to the pad. Over the course of their development, the rocket and spacecraft have moved from design and manufacturing to testing and assembly and integration. Some of the hardware has even been delivered to the launch pad at NASA’s Kennedy Space Center in Florida. Along with the Gateway in lunar orbit and a new human landing system, SLS and Orion create the backbone for the agency’s Artemis missions to the Moon that will land astronauts on the lunar surface by 2024 From the top to the bottom, you can take a look at the completed flight hardware for SLS and Orion for the first flight, Artemis I, in this latest video. For more information about Artemis, https://www.nasa.gov/artemis. (NASA)

This video animation shows how the forward join — or upper part — of the core stage was assembled for NASA’s Space Launch System (SLS), America’s new deep space rocket. The forward join connects three structures: the liquid oxygen tank, intertank and forward skirt. The forward join is the first of three major assembly jobs required by NASA and Boeing, the SLS prime contractor, to complete the massive, 212-foot-tall SLS core stage. Assembly of the stage, which will be the largest rocket stage ever produced, takes place at NASA’s Michoud Assembly Facility in New Orleans.

To ensure NASA’s Space Launch System rocket is ready for Exploration Mission-1, the first integrated flight that will send the Orion spacecraft beyond the Moon, engineers are performing a series of tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Crews loaded the 149-foot liquid hydrogen tank structural test article, the largest piece of structural test hardware for the core stage of SLS, into Test Stand 4693 Jan. 14. Dozens of hydraulic cylinders in the test stand will push and pull on the tank to simulate the stresses and loads it will endure during liftoff and flight. Test Stand 4693 is one of the newest test stands at Marshall, and the liquid hydrogen structural test article is the first piece of hardware to be tested in the stand.

The largest spacecraft welding tool in the world, the Vertical Assembly Center officially is open for business at NASA's Michoud Assembly Facility in New Orleans. The 170-foot-tall, 78-foot-wide giant completes a world-class welding toolkit that will be used to build the core stage of America's next great rocket, the Space Launch System (SLS). SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and eventually Mars. The core stage, towering more than 200 feet tall (61 meters) with a diameter of 27.6 feet (8.4 meters), will store cryogenic liquid hydrogen and liquid oxygen that will feed the rocket's four RS-25 engines.

The most complex 3-D printed rocket injector ever built by NASA roars to life on the test stand at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama, are wrapping up acoustic testing on a 5-percent scale model of NASA's Space Launch System. The Aug. 28 test, the 34th in the series, will help NASA engineers understand how loud the SLS vehicle will be during liftoff. Data from the test series will be used to design the water sound suppression system that reduces liftoff vibrations on the vehicle. SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and ultimately to Mars. (NASA/MSFC)

Stennis Space Center engineers, in preparations to test the core stage of NASA’s Space Launch System, moved the 1.2 million pound Main Propulsion Test Article (MPTA) structure on the B-2 Test Stand to accommodate the height of the SLS core stage. The stage will be taller than the Apollo/Saturn first stage and the space shuttle MPTA, which was built in the late 1970s for space shuttle propulsion testing. After the move, another 1 million pounds of steel will be added to extend the structure 100 feet higher, a task targeted for completion by year’s end.

A quick look at what's been going on in the Orion, Space Launch System and Ground Systems Development and Operations programs in April, May and June of 2014.

Beginning Aug. 5, anti-geyser testing is underway at NASA's Marshall Space Flight Center for the agency's Space Launch System (SLS) -- the rocket that will make deep space missions possible, including to an asteroid and ultimately to Mars. A full-scale replica of the SLS liquid oxygen tank feed system -- which will be housed in the rocket's core stage -- is set up on one of Marshall's test stands to show that proven procedures will keep the tank's thousands of gallons of oxidizer from geysering. As propellant is poured into the system from the bottom, helium is injected into different points along two feed lines that deliver the propellant all the way up to the tank. The helium induces circulation almost like stirring and keeps the propellant uniform and at the right temperature. Testing is scheduled to be completed in November. (NASA/MSFC)

A special piece of hardware called a low-profile diffuser is being designed, built and tested at NASA's Marshall Space Flight Center in Huntsville, Alabama, for propellant tanks. The diffuser maintains the density and required flow rate of the propellant. Using a smaller diffuser can free up space to raise the liquid level -- potentially increasing the amount of payload that can be carried on future launch vehicles, like NASA's Space Launch System, or SLS. (NASA/MSFC)

NASA is testing on one of the largest composite cryogenic rocket fuel tanks ever manufactured at Marshall Space Flight Center in Huntsville, Alabama.

Engineers test a model of the 70-metric-ton Space Launch System -- NASA's heavy-lift launch vehicle that will carry crew, cargo and science missions into deep space -- at the Langley Research Center in Hampton, Virginia. This testing will help engineers at NASA's Marshall Space Flight Center in Alabama better understand the performance of the integrated system and fine tune the performance of the vehicle.

A 5-percent scale model, including solid rocket motors, of NASA's Space Launch System (SLS) is ignited to test how low- and high-frequency sound waves will affect the rocket on the launch pad. The data collected from the tests will be used to help direct and verify the design of the rocket's sound suppression system. SLS will be the most powerful rocket in history for deep space missions, including to an asteroid and ultimately to Mars. (NASA/MSFC/David Olive)

Engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., are using the latest technology -- 3D printing -- to make parts for a scale model of NASA's new rocket, the Space Launch System (SLS). The model is being used for acoustic testing, which will show how the powerful noise generated by the engines and boosters may affect the rocket and crew, especially during liftoff. The data will then be used to verify the design of the rocket's sound suppression system. (NASA/MSFC)

2014 is off to an amazing start as NASA rockets toward this year's launch of Exploration Flight Test-1!

Designed to be a combustion test facility for the U.S. Army in 1956, Marshall's test control and data acquisition center is now state-of-the-art. Marshall's test lab supports projects — NASA and other government agencies, plus commercial space — large and small.

NASA and ATK engineers complete structural loads testing on the Space Launch System (SLS) booster forward skirt at ATK's facility in Promontory, Utah. Structural loads tests are performed to ensure each piece of hardware can endure loads without any adverse effects to the vehicle, or most importantly, to the crew. (ATK)

NASA will test the core stage of its new Space Launch System vehicle on the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Miss. Renovation of the stand for the test series is under way. A major milestone is the renovation of the main derrick crane, which sits atop the stand and will be used to lift the core stage into place for testing. The existing crane must be dismantled and significantly upgraded to handle the SLS stage, which is nearly 50 percent longer than the Saturn stages previously tested on the stand. Part of the removal is captured using time-lapse video.

Nyla explains the need for testing the newly installed piping on the A-1 test stand using liquid nitrogen in preparation for testing the RS-25 engines that will power the SLS.

A quick look at what's been going on in the Orion, Space Launch System and Ground Systems Development and Operations programs.

Mini models of the Space Launch System (SLS) core stage engines are ignited in a big way for a short-duration hot-fire test. As the main objectives of the Pathfinder Test Program, models of the SLS core stage RS-25 engines and solid rocket boosters -- scaled down to just 2 percent of the actual size of the flight hardware -- have been designed, built and hot-fire tested at sea-level conditions by Marshall Space Flight Center engineers, in close collaboration with Calspan-University of Buffalo Research Center Inc. in Buffalo, N.Y. The replicas will provide data on the convective heating environments that the base of the vehicle will experience upon ascent. The models were developed for base heating testing scheduled for this summer. When completed, SLS, NASA's new rocket, will be one of the biggest, most powerful rockets ever built.

The adapter that will connect NASA's Orion spacecraft to a Delta IV rocket for Orion's first mission in September is complete. During Orion's first mission, called Exploration Flight Test-1, the spacecraft will travel to an altitude of approximately 3,600 miles above Earth's surface before re-entering the atmosphere traveling approximately 20,000 mph at temperatures above 4,000 degrees Fahrenheit. The uncrewed flight will provide engineers with important data about Orion's heat shield and other elements, including the adapter's performance before it is flown in 2017 as part of the first SLS mission. (NASA/MSFC/Anthony Orton)

On sea, land and in the sky, NASA's Orion, Space Launch System and Ground Systems Development and Operations continued making progress toward sending humans beyond Earth's orbit during the past quarter.

The modern avionics system that will guide NASA's Space Launch System (SLS), the most powerful rocket ever built, has seen the light. The flight software and avionics for SLS were integrated and powered for testing Jan. 9 at NASA's Marshall Space Flight Center in Huntsville, Ala., as part of a milestone known as first light. The milestone enables early integration and testing of avionics and software to help NASA perfect the system and ensure the units communicate together as designed. Avionics tell the rocket where it should fly and how it should pivot its engines to stay on course. (Boeing)

NASA completed a series of high-tech can-crushing tests as an enormous fuel tank crumbled under the pressure of almost a million pounds of force, all in the name of building lighter, more affordable rockets. The rare test with an aluminum-lithium cylinder as large as a full-size rocket fuel tank was conducted inside the structural test area at NASA's Marshall Space Flight Center in Huntsville, Ala. (NASA/MSFC)

The foundation has been poured for the Vertical Assembly Center (VAC) in support of NASA's Space Launch System (SLS). The VAC, measuring 170 feet tall and weighing 3 million pounds, will be one of the largest friction-stir-welding tools in the world. It took 90 truckloads of material to pour the 900 cubic yards of concrete to support the VAC. The tool will be used to weld together the barrel sections of the liquid oxygen and liquid hydrogen tanks for the SLS. (NASA/MSFC)

Hardware that will keep harmful gases away from the Orion's spacecraft during its first trip to space proved it won't bend under pressure during a recent test at NASA's Marshall Space Flight Center. The diaphragm for Exploration Flight Test (EFT)-1 was joined to an adapter prototype for pressurized testing. For the test, the adapter was sealed and a vacuum pump was connected to the diaphragm. The vacuum pressure simulates atmospheric conditions the hardware may experience during the mission. (NASA/MSFC)

Technicians at NASA's Langley Research Center in Hampton, Va. move an 85,000-pound cart on air cushions into the test section during the Space Launch System (SLS) Liftoff Transition testing in the 14 X 22 Subsonic Wind Tunnel. The interchangeable carts are used to support and articulate the nearly six-foot SLS model during wind tunnel testing.

J-2X Engine No. 10002 is test fired for the final time on the A-1 test stand at NASA's Stennis Space Center. The 330-second test was the last in a series of gimbal, or pivot, tests on the engine. Following the removal of this engine, the test stand will be modified to begin RS-25 engine testing. J-2X testing has provided valuable data and experience for the team developing the RS-25 engine, which will power the core stage of NASA's new Space Launch System. (NASA/SSC)

A 3-D printed injector roars to life on a test stand at NASA's Marshall Space Flight Center in Huntsville, Ala. The injector fabricated with a technique called 3-D printing, or additive manufacturing, produced a record 20,000 pounds of thrust and was the largest rocket engine part of its kind tested by NASA to date. (NASA/MSFC)
