NASA is aiming to fly its huge, next-generation rocket, the House Launch System, for the primary time in February of 2022, a crucial check flight on NASA’s journey to ship folks again to the Moon. Nevertheless, loads of assessments nonetheless must go effectively earlier than the much-delayed car can lastly take flight.

Affirmation of the brand new goal date, which was rumored in August, comes a day after engineers absolutely stacked the House Launch System, or SLS, inside NASA’s huge hangar at Kennedy House Middle in Florida. Standing at 322 ft excessive, the SLS rises taller than the Statue of Liberty. On high of the stack is NASA’s Orion crew capsule, a brand new spacecraft that’s been developed to hold folks into deep house. Nevertheless, when the SLS flies for the primary time subsequent 12 months, there gained’t be any folks on board. The check mission will ship an empty Orion capsule on a four- to six-week-long journey across the Moon.

SLS’ debut flight is named Artemis I, the primary main flight in NASA’s Artemis program. If the flight is profitable, the SLS and Orion’s subsequent mission can be Artemis II, which is able to carry NASA astronauts on an analogous trajectory across the Moon. This system will culminate with touchdown the primary girl and the primary particular person of coloration on the floor of the Moon. Throughout the Trump administration, Vice President Mike Pence challenged NASA to make this touchdown occur as early as 2024.

That timeline has since been referred to as into query, given the complexity of the mission and quite a few delays. Initially, NASA envisioned the SLS flying for the first time back in 2017, however its debut has been constantly pushed again time and again due to improper management and cost overruns. Within the meantime, NASA additionally wants a lunar lander to carry folks all the way down to the floor of the Moon, which the SLS and Orion can’t do alone. The house company awarded SpaceX a contract to develop its new vehicle, called Starship, to take folks to the Moon’s floor. However the car nonetheless has a protracted highway of growth forward, and lawsuits filed by competitor Blue Origin, which didn’t obtain the NASA contract, have sophisticated the method. Then there may be nonetheless the matter of growing new spacesuits, which could also hold up the timeline.

Regardless of all that, NASA hasn’t fairly given up on the 2024 goal date, even after Joe Biden turned president. “It’s a stretch, it’s a problem, however the schedule is 2024,” NASA administrator Bill Nelson said in June. Nelson additionally recently acknowledged the sheer quantity of labor and obstacles that should be overcome.

For now, NASA is usually centered on getting Artemis I off the bottom. If all goes effectively, NASA plans to roll out the absolutely stacked SLS out to the launchpad late this 12 months. Early subsequent 12 months, the mission group will conduct what’s generally known as a moist costume rehearsal, the place they’ll fill the rocket with the identical propellants it can use for flight however with out igniting the rocket’s engines. As soon as that’s full, NASA will then roll the rocket again to its hangar for extra checks earlier than rolling it to the launchpad once more forward of the flight.

“I inform you I couldn’t be prouder of the group that bought us to the place we’re at this time, regardless of the a number of challenges that we confronted with COVID and main storms — most not too long ago, Hurricane Ida — and the impacts that had on our testing amenities,” John Honeycutt, the SLS program supervisor at NASA’s Marshall House Flight Middle, stated throughout a press convention at this time.

As of now, Artemis I has three completely different launch home windows: one in February, one in March, and one in April. Every window, dictated by how the Earth is shifting about its axis and the Moon’s rotation round our planet, is roughly 15 days lengthy, with the primary window opening on February twelfth. The timing of the launch throughout the window dictates how lengthy Artemis I’ll keep in house, making it both a four-week mission or a six-week mission.

As soon as Artemis I is full, then comes Artemis II with a goal launch date someday in 2023. For that flight, folks can be on board, which suggests the car will want much more additions, notably a life assist system. NASA wouldn’t say whether or not the newest SLS delays have pushed again Artemis II, solely that an replace is on its means.

“I believe the company is continuous to take a look at that; we’re evaluating the standing of that mission,” Tom Whitmeyer, deputy affiliate administrator for exploration programs growth at NASA, stated throughout at this time’s press convention.
