NASA will be watching the weather early Saturday morning to make sure it's safe to begin fueling the 32-story rocket with its 736,000 gallons of super-chilled propellant at about 5:45 a.m. After solving some technical issues that caused the first launch scrub on Monday (Aug.

It's important to note the operating system is efficient enough not to require tons of compute power, but still. NASA has only planned (and budgeted) for this single test flight before putting humans on the next flight of SLS, expected in 2024. What's worse, the expected cost per launch of SLS is looking to be about eight times what was initially expected. Everything that NASA learns from Artemis is meant to then inform plans for the first missions to Mars in the 2030s. This first test flight will send an uncrewed Orion capsule around the moon and test some technology along the way before coming in for a blistering hot reentry through Earth's atmosphere and a splashdown landing. The SLS used for
NASA officials will hold a news briefing Friday ahead of their next attempt to launch of its new moon rocket.
The first attempt on Monday was thwarted by engine trouble. Watch in the player above. The event is scheduled to begin at 9 a.m.
NASA has restarted the countdown for the first SLS launch after concluding a faulty sensor caused the initial attempt to scrub earlier in the week.
Weather forecasts for the launch are more favorable, with a 60% chance of acceptable weather for the Sept. “We were off the script in terms of the normal tanking operation,” he said. Because of that, the data from the faulty sensor does not need to be “masked” or hidden from the flight computer for the countdown to proceed. “We do not need the sensor for flight.” “We’ve had time to go back and look at the data and compare many sources of data, and do some independent analysis that confirmed it’s a bad sensor and we’re getting good quality propellant through the engine.” This will be the second attempt to launch the SLS
Ground teams at Kennedy Space Center in Florida on Friday began a final full day of launch preparations on the eve of a second attempt to send NASA's giant, ...
The SLS and Orion have been under development for more than a decade, with years of delays and ballooning costs that have run to at least $37 billion as of last year. After that, regulations limiting how long a rocket can remain at its launch tower would likely require the spacecraft to be rolled back to its assembly building before another liftoff attempt, Parsons said. "I do not expect weather to be a show-stopper by any means for either launch window." space agency has built since the Saturn V rocket of the Apollo era. EDT (1817 GMT), as well as for a backup launch time on Monday. Space Force in Cape Canaveral, said forecasts called for a 70% chance of favorable conditions during the two-hour Saturday launch window, which opens at 2:17 p.m.
NASA aimed for a Saturday launch of its new moon rocket, after fixing fuel leaks and working around a bad engine sensor that foiled the first try.
Here's what you need to know about Artemis I and the second attempt to launch the Space Launch System and Orion capsule.
The Space Launch system’s cargo on Monday is Orion, a capsule that is designed for trips of multiple weeks beyond low-Earth orbit. The one waiting on the pad to launch on Monday is 322 feet high, and will weigh 5.5 million pounds when filled with propellants. The rocket, known as S.L.S., has some visual similarities to the retired space shuttles. If the launch is postponed again, NASA may also try to lift off on Monday, Sept. It will not have a crew aboard for this flight but can carry up to four astronauts. A technical hiccup kept NASA’s giant moon rocket, the Space Launch System, from getting off the launchpad on Monday. A launch attempt after that could be later in September, or in October. If the engine was too warm, it could have shut down during liftoff. In the case of unfavorable weather or technical glitches, the liftoff can be pushed back by as much as two hours, to 4:17 p.m. The launch is scheduled for 2:17 p.m. The Space Launch System is that rocket — the most powerful one since Saturn V took NASA astronauts to the moon in the 1960s and 1970s. The agency’s full coverage will begin at 12:15 p.m.
Fuel leaks and a bad engine sensor foiled Monday's attempt, managers say they have now addressed the problems.
Godspeed, take two. NASA will try a second time to launch its Artemis I rocket from Kennedy Space Center.

Everything from winds to humidity to trees can change what you hear and feel. If you are going to be outside waiting for the launch, expect typical summer in Florida weather said Cassie Leahy, a meteorologist at the National Weather Service's Melbourne location. [Cocoa Beach Pier](http://www.cocoabeachpier.com). If successful, it will pave the way for astronauts to fly a similar profile on Artemis II no earlier than 2024. Traffic is going to be heavy. This is a test flight for the SLS rocket, which will later carry astronauts to the moon.

NASA scrapped its first attempt to launch Artemis I earlier this week, but a new launch is set for Saturday. How to watch the new moon mission.
NASA Artemis I launch Live updates: NASA is getting ready for a critical second attempt at launching its Artemis 1 mission to the moon after a setback on ...
The launch will be the second attempt at the mission, after the initial launch attempt on August 29 had to be called off due to technical issues including a problem with one of the rocket’s four main engines. In our live blog we will follow all the updates on NASA’s critical Artemis 1 launch, which is part of a broader mission to put humans back on the moon. NASA is set to make its second attempt to launch the Artemis I rocket on Saturday, September 3, 2022 at 2:17pm Florida time.

NASA is encountering new problems with its second attempt to launch its massive Space Launch System rocket and Orion spacecraft to the moon.
This time, they used helium to pressurize the line, but this did not work either. They also started loading the liquid hydrogen, but at about 7:15 a.m. But when they started to reflow the hydrogen, they noticed another leak.
NASA's new moon rocket sprang another hazardous leak Saturday, as the launch team began fueling it for liftoff on a test flight that must go well before ...
The launch team planned to ignore the faulty sensor this time around and rely on other instruments to ensure each main engine was properly chilled. If not, the resulting damage could lead to an abrupt engine shutdown and aborted flight. On Monday, hydrogen fuel escaped from elsewhere in the rocket. People last walked on the moon 50 years ago. NASA wants to send the crew capsule atop the rocket around the moon, pushing it to the limit before astronauts get on the next flight. But minutes later, hydrogen fuel began leaking from the engine section at the bottom of the rocket.
