I did some searching and found a summary of the mission's Abort modes. Pad Abort: If an emergency occurs before liftoff while astronauts are on the launch pad, the Emergency Egress System allows them to slide down cables in baskets to safety, while the Launch Abort System (LAS) can pull the capsule away from the rocket. Ascent Abort: During the initial ascent phase, the LAS (a 44-foot tower) uses powerful motors to separate the Orion capsule from the SLS rocket and steer it to a safe Atlantic Ocean splashdown. Ascent-Once-Around (AOA): If an anomaly occurs after the LAS is jettisoned but before the Translunar Injection (TLI), the spacecraft can use its service module to perform an abort once around Earth, reentering the atmosphere for a Pacific Ocean recovery. Lunar Abort: Once the spacecraft is en route to the Moon, the only option is a free-return trajectory, which uses the Moon's gravity to swing the spacecraft back toward Earth without needing a powered return burn.

@NathanJRobinson Imagine going a quarter of a million dollars in debt to study something interesting. One might applaud your commitment to scholarship, but also question your judgment.

imagine studying something because you find it interesting rather than because of the "return"

RE: The Moon Launch OK, look, I admit it. I am an astronaut fanboy nerd (except for one ex-astronaut politician whose head resembles a scrotum). If you are a late Boomer or early Gen Xer, you remember. You heard Genesis read from an astronaut orbiting the Moon. You and all your friends wanted to be astronauts, more than anything. You remember that your parents bought your family’s first color TV to watch Neil Armstrong on the Moon. You built the LEM and CSM models and only killed a few brain cells with the glue. You were scared and prayed during Apollo 13. You had the lunchbox. You were sad when they cut off funding for the rest of the Moon landings. You were amazed when they saved Skylab. You watched all the movies. (You saw “The Right Stuff” and “Apollo 13” at least 20 times each.) You cried over Challenger and Columbia. You got older and wondered why we became so timid. Why not more of the Moon? Why not Mars? Why not beyond? The ISS seemed so…. limiting. You always said that the US space program was the one thing you did not care how much your were taxed for. Elon became a god of space travel, and you were there for it. So it’s our day, fellow astronaut nerd fanboys and fangirls. Put on your make-believe astronaut beanies and goggles, be 8 again, and remember the way you took that refrigerator cardboard box and turned it into the inside of an Apollo capsule with magic markers, Scotch tape and buttons stolen from your Mom’s sewing box. WE’RE GOING BACK TO THE FREAKING MOON BABY!!!!!🚀❤️🤍💙🇺🇸

Using Fukushima as an example: Western media (lead by the US) published article after article condemning nuclear power and implicating Japan for its role in "allowing" the disaster and "endangering millions". The reality was that the Fukushima system was brilliantly engineered and stood up to a combination of a 9.0 earthquake and resulting 50'(!) tsunami that no one would have reasonably predicted. The plants' shutdown systems worked even though they should have been overwhelmed by the elements. There were NO direct deaths as a result of the accident and only six casualties (including one death) a few years later which could be ascribed to the meltdowns. US media published fear mongering maps showing radioactive spread across the Pacific and providing little context when the reality was that the increase in radiation was roughly the equivalent of eating an extra banana. (Yes, bananas have trace amounts of radioactivity). Meanwhile the evacuation panic around the plants resulted in over 2000 deaths due to stress, suicide, or loss of medical care. Japan has nothing to be ashamed of when the discussion turns to Fukushima, but US media certainly do. Not that they are capable of shame, of course.

The past few days have convinced me that some sinister forces were running a massive social media psyop on the Japanese to convince them that Americans don’t like them, when in truth one of the few things most of us agree on is that Japan is pretty cool.

@emzanotti Audio was good, but that clumsy speech that the launch director delivered to the crew was IMHO unnecessary. It was the only time that it felt like NASA was playing for the cameras and it did not play to anyone's strengths.

I have laughed harder at the SNL UK clips on YT than I have at the vast majority of recent SNL US clips. The fake ads (Underágé anti-aging cosmetics 😆) the digs at British tourist behavior, and of course their take-no-prisoners mockery of politicians, "elites", and celebrities - all an order of magnitude more enjoyable than the current US offering.

@jon_stokes Launch was 11:38AM Eastern / 8:38AM Pacific, so it fit perfectly into the morning schedule for schools. I suspect that more kids than adults actually saw it live.

I watched it on one of these, and lol no they did not wheel this into my 5th grade classroom expressly to show us a replay of that teacher & crew exploding. We watched it live along with a ton of other kids across the country.

99.9% of people who "experienced" the Challenger disaster saw it on replay and now remember it as live. Almost NO ONE was watching. Everyone thinks they were. It's a fascinating collective false memory.

Holy crap! That is just an elaborate suicide attempt.

@DaddyWarpig This guy had a vid for this "don't tell her to calm down. Tell her she's becoming just like her mother and that you didn't sign up for this because if you married her mother you'd have a clean house and a warm meal."

@BlueBoxDave THIS. Shylock is so well written that many (perhaps most) people think that he is the protagonist of the play and the "merchant" in the title.

My Dad played drums in his youth and even got to sit in once with Bix Beiderbecke's band. I feel fortunate that he had me listen to big bands when I was learning to play 'cause guys like Gene Krupa, Buddy Rich, and Louis Bellson made you want to put in the time to sound like that.
