NASA launches huge Moon rocket – here’s what you need to know

WASHINGTON: NASA’s massive new rocket began its first journey to the launch pad on Thursday ahead of a series of tests that will clear it to blow up Moon this summer.
It left the Kennedy Space Center Vehicle Assembly Building at about 5:47 p.m. Eastern Time (2147 GMT) and began its 11-hour journey on a crawler transport to the Launch Complex. sacred 39B, four miles (6.5 km) away.
About 10,000 people gathered to watch the event.
With the Orion crew capsule fixed to the top, Block 1 of the Space Launch System (SLS) is 322 feet (98 meters) tall – taller than the Statue of Liberty, but slightly smaller than a Saturn rocket The 363-foot V powered the Apollo mission to the Moon.
Even so, it will generate a maximum thrust of 8.8 million pounds (39.1 Meganewtons), 15% more than the Saturn V, meaning it is expected to be the most powerful rocket in the world at the time. it started working.
“Ladies and gentlemen, the world’s most powerful rocket ever is here!” NASA Administrator Bill Nelson addresses a crowd. “We imagine, we build, we constantly push for what’s possible.”
A symbol of US space ambitions, it also comes with a hefty price tag: $4.1 billion per launch for the first four Artemis missions, NASA Inspector General Paul Martin told Congress this month.
After reaching the launch pad, about two more weeks of testing is needed before what is known as a “wet suit rehearsal”.
The SLS team will load more than 700,000 gallons (3.2 million liters) of cryogenic propellant into the rocket and practice each stage of the launch countdown, pausing 10 seconds before detonating.
NASA is targeting May as the earliest window for Artemis-1, an unrealized lunar mission that will be the first integrated flight for SLS and Orion.
The SLS will first place Orion in low Earth orbit, and then, using its upper stage, perform a so-called trans-moon injection.
This maneuver is needed to take Orion 280,000 miles beyond Earth and 40,000 miles away from the Moon – farther than any human-capable spacecraft has ventured.
During its three-week mission, Orion will deploy 10 shoebox-sized satellites called CubeSats to collect information about the deep space environment.
Its “passengers” will include three radiation data collection dummies and a Snoopy toy, long a NASA mascot.
It will cruise around the far side of the Moon, using propulsion provided by the European Space Agency (ESA), and eventually return to Earth, where its heat shield will be tested with the atmosphere. book.
Splashdown took place in the Pacific Ocean, off the coast of California.
Artemis-2 will be the first crewed test flight, orbiting the Moon but not landing, while Artemis-3, planned for 2025, will see the woman and the skin. the first color touches the south pole of the Moon.
NASA wants to build a long-term presence on the Moon and use it as a proof-of-concept for the technologies needed for a Mars mission, sometime in the 2030s, using SLS’s Block 2 evolution .
NASA calls the SLS “a super-heavy elevator probe.” The only superheavy rocket currently in operation is SpaceX’s Falcon Heavy, which is smaller.
Elon Musk’s company is also developing its own deep space rocket, the fully reusable Starship, which he says will be ready for an orbital test this year.
The Starship will be bigger and more powerful than the SLS: 394 feet tall with 17 million pounds of thrust. It can also be significantly cheaper.
The mogul has suggested that within years, the cost per launch could be as little as $10 million.
Direct comparisons are complicated by the fact that while the SLS is designed to fly directly to its destinations, SpaceX anticipates putting a Starship into orbit, then refueling it with a Starship. other so that it can continue its journey, in order to extend its range and payload.
NASA has also contracted out a version of Starship as a lunar vehicle for Artemis.
Other super-heavy rockets in development include Blue Origin’s New Glenn, China’s Long March 9 and Russia’s Yenisei.
