PaladinSolo Posted August 29, 2022 Share Posted August 29, 2022 That is if it doesn't explode spectacularly or isn't scrubbed. This mission will be unmanned and test stress and radiation levels as it orbits the moon, but this is the most powerful rocket ever designed. Edit: Todays launch was cancelled due to an issue to the #3 engine. 1 Quote Link to comment Share on other sites More sharing options...
mclumber1 Posted August 29, 2022 Share Posted August 29, 2022 I woke up early to watch this, only to see the launch scrubbed. But that's ok! I'd rather the mission be a complete success than cause a RUD. NASA has spent more than $20 billion on the SLS and Orion programs to get to this point, so if they need to take a few extra days to troubleshoot, I'm fine with that.

CayceG Posted August 29, 2022 Share Posted August 29, 2022 I really hope it launches this Friday. This is pretty monumental, if only for prestige. Manned spaceflight isn't the most important thing NASA's money goes to, but damned if it isn't cool as hell. Quote Link to comment Share on other sites More sharing options...
Commissar SFLUFAN Posted August 31, 2022 Share Posted August 31, 2022 Some further information on the scrubbed launch: Warning sign? NASA never finished a fueling test before today’s SLS launch attempt ARSTECHNICA.COM "I am very proud of this launch team." Quote Despite all of the hard work by its engineers and technicians, NASA did not really get close to firing up the massive Space Launch System (SLS) rocket on Monday. The rocket experienced several issues during the countdown early on Monday before running into a technical problem the launch team could not solve: an RS-25 rocket engine that did not properly chill down prior to ignition. Even if the engine problem had been resolved, weather along the Florida coast on Monday morning proved dicier than anticipated. Space is hard, certainly. But Monday's attempt—which NASA had promoted heavily by inviting celebrities to the launch and which included a visit by Vice President Kamala Harris—was perhaps a bit rushed. Why? Because NASA rolled a rocket out to launch without accounting for all of the things that could go wrong. To their credit, the launch controllers successfully worked through a host of issues on Monday prior to the scrub. For example, fueling operations started nearly two hours late due to lightning in proximity to the launch pad. This forced the team to push hard through a compressed timeline ahead of a launch window that opened at 8:33 am ET (12:33 UTC). Once the launch team got into propellant loading, work to fill the large liquid hydrogen tank was stymied by a leak at an 8-inch inlet leading into the tank. This problem was ultimately resolved by stopping the process and then restarting propellant loading—yes, NASA resolved the problem by essentially turning off the SLS and turning it back on again. After this, the countdown proceeded reasonably smoothly for about an hour until a problem with one of the rocket's four main engines. As part of the pre-launch process, cryogenic propellant is "bled" from the fuel tanks into the engines to chill them to about 5° Celsius prior to flight. (In responding to a question about the engine temperature, Artemis I Mission Manager Mike Sarafin actually gave the temperature as "500 Rankine.") In troubleshooting this engine issue, launch controllers could not find a way to address what appears to have been a problem on the core stage side of the vehicle. So the launch attempt was scrubbed.

Jwheel86 Posted September 4, 2022 Share Posted September 4, 2022 Given that the lander is a version of Starship that'll be going back and forth between LEO and the Moon to refuel, I don't see the advantage of SLS anymore. Use Dragon to transfer the crew to the lander while in LEO. Quote Link to comment Share on other sites More sharing options...

The HLS is only used to land on the moon and return to the Gateway. The HLS I believe never returns to LEO and even if it did return it would only be for refueling unmanned.

Commissar SFLUFAN Posted November 16, 2022 Share Posted November 16, 2022 NASA gets its mojo back with a stunning nighttime launch of the SLS rocket ARSTECHNICA.COM The US space agency had not launched an orbital rocket since 2011. Quote The skies were auspicious during the wee hours of Wednesday morning, as the Artemis I mission ticked down its final seconds until liftoff. Ten, nine, eight seconds ... Shining brightly, near the southern horizon, was the constellation Orion, namesake to NASA's new deep space vehicle. Seven, six, five ... Hanging almost directly overhead the launch tower was a half Moon, the destination of the Artemis I mission. Four, three, two and one ... Suddenly, the night lights came not from the stars pricking the night sky, nor the fat Moon overhead. Rather, the rocket roared to life, its massive solid rocket boosters pushing it upward. As the rocket ascended, it left in its wake a tremendous pillar of exhaust, evocative of Jack's giant beanstalk. Several seconds after liftoff, the sound and fury and acoustic energy of the Space Launch System thundered outward. For a moment, it was deafening. And then, it was gone. But the rocket pushed onward and upward, sending its payload, the Orion spacecraft and its service module, toward the Moon. For the first time in more than half a century, a spacecraft capable of carrying humans is on its way back to the Moon. The next time it flies, four astronauts will be on board. 1 Quote Link to comment Share on other sites More sharing options...
thewhyteboar Posted November 16, 2022 Share Posted November 16, 2022 My daughter loves to play rocket ship with me (I zoom her into the air while singing a song) so I showed her the launch. She thought it was pretty cool. 1 Quote Link to comment Share on other sites More sharing options...
