Great job...looks pretty good for just a cell phone camera!

This is awesome. I enjoyed your video. Thanks for posting. 🙏

It was earlier than 1130 for sure. I saw it out of my office window. The contrails were there until after 3pm est

My 8th grade teacher was probably my fave science teacher too. She was young and hopeful, a great teacher and very passionate.

My sister (still horse mad and utterly disinterested in science and technology, now as then) heard about it on the news and rather matter of factly told me 'Oh, the space shuttle exploded' in passing, along with some trivia she gave equal weight to.

I went to my room and cried. For both the astronauts who'd died and because I knew the space program would be halted for a long while.

Okay so 16,000 kg to TLI is equal to 26-27,000kg TLI? I was talking about 2023 block Falcon Heavy, not starship, Vulcan, or New Glenn. I will give you it’s not 3x this month, it is 1.7-1.8x, and 2-3x neighborhood is designed and assembly lines with known manufacturing techniques operating right now and has been fitted to test stands. Falcon Heavy isn’t going to get another block in the next 2-3 years, we know that for sure as of Dec 2018.

My mom tells the story of how they were watching it because the teacher taught in her school district. It's awful to think her teacher may have known the woman who died

The next frontier of lunar exploration is gonna be lava tubes, and neither NASA nor ESA are gonna use humans for that (at least at first). I agree that nothing but SLS can put humans back on the Moon, but I still think the money would be better spent on robotic missions that could do all the same science, and then some, without the added cost of human-rating or the added risk (or eventuality) of deaths putting a damper on mission goals.

I still don't understand why putting humans on the moon again is on the table besides "well China says they're gonna do it, so... we gotta do it first to stake a claim."

The shuttle wasn’t the best launch system. Challenger both was a tragedy and evidence of the issue.

I’m 44 and I was in elementary school at the time. We watched live from class and I can remember how the room went from excited and lots of talking to pretty much dead silence. The only sounds you could hear were light sobs and tears falling. I still get emotional thinking about that day.

Then fast forward many years later in 98 or 99, I was in college and taking a Space Science course. My professor actually knew Christa McAuliffe and he wept in front of class while talking about it.

It's insane. There's a really good book about it called We Dream of Space by Erin Entrada Kelly

We also briefly covered it in our 6th grade science class, I believe our teacher applied, but didn't make too far due to health conditions.

Yes, I said hypothetical to both. Either you compare the vehicles that are flying today or you compare hypothetical vehicles from 4-5 years in the future.

In either scenario SLS IS NOT carrying 3 times the payload of its competition.

BTW Block II will have completely new SRBs, a new upper stage and a new version of the RS-25. Hardly “80%-90%” of what was used on Artemis I

I read hot, young variable stars and immediately thought this was the NSFW r/space 🤣

That’s some real trauma, especially as a 2nd grader. I experienced it too. I was in 6th grade and lived in Melbourne, Florida about 30 miles from KSC. I remember going to school that morning and it being one of the coldest days I’d ever experienced in Florida. I usually rode my bike to school but my dad drove me that day because it was so cold. We went outside and watched it live like we usually did, but we all knew something had gone terribly wrong this time. No one could focus for the rest of the day.

Hard to say. There are many cool Exoplanets, if I had to put my finger on just one though it would probably be Kepler-62f a super-earth orbiting within the HZ of a K-type main sequence star. But Kepler-442b and Kepler-47c aren't too far behind

Lapulapu's forces being 1500+ is a extremely heavy overexaggeration, the censuses from that century show it would only be a small fraction of that number.

And he wasnt stupid for thinking he could win; a small armored force defeating a large force of indigenous tribes isn't that rare, if anything this should have been an easy victory. Lapulapu was just a better tactician, or more so Magellan was a poor tactician.

Hypothetical also applies to starship HLS and its in orbit refueling, and at least one orbital HLS tanker.

I think they will do it, SpaceX and SLS, just saying we know SpaceX stopped investing in Falcon heavy performance because the math didn’t work for non-LEO missions in 2018. Falcon Heavy BFR is more hypothetical than a vehicle and 80-90% (may be more like 98% as the biggest changes to 1B is just more main tank and SRB fuel capacity segments) of its components that just launched on SLS that will be reused for the newer blocks, as well as the Starship HLS and tankers prototype testing in Texas hopefully kicking off next month. Though the first lunar orbital flight TBD, but hopefully when you suggest, but if we adjust for SpaceX delivery estimation historically 2027-2028 worst case for a crewed NASA lunar mission.)
