Telvanni tower on the moon would certainly be something.

And the missing 2-3x of disposable Falcon Heavy mass to LTI? SpaceX could have funded the Rad hardened Dragon 7 years ago without NASA funding if they wanted to, but felt Starship was a better investment given the large expense and missing capabilities NASA required of its vendors.

Yep, I was watching it in the physics classroom at lunchtime - on the east coast. There were about 30 students and about as many teachers in there. There weren't many TVs in the school. That was the classroom that had the sample of a shuttle heat tile that NASA sent to schools and my physics teacher set up a little viewing event. My 4th period teacher (right after lunch) was in the room and she said I could stay there and watch.

There were no mobile phones, no social media, no internet. AV had a few TVs on carts (the red asphalt type safety movies were all on VHS by then, though still a lot of film strips/loops still in use). They set up TVs in the auditorium and let students go watch. Hard to get students to focus after that, and the historic nature of the event wasn't lost on anyone.

No it wouldn’t. An earth-like composition for Kepler 22b was ruled out.

NASA is paying to radiation harden Dragon. Dragon will be launching cargo to the Lunar Gateway. source

SpaceX is focusing on Starship because it's a better design. But NASA could have absolutely funded a crew-rated, radiation hardened version of Dragon.

SLS isn’t rad hardened. The only part that even leaves LEO is the ICPS and that’s just taken from the Delta III.

Falcon Heavy in expendable mode has a TLI of about 20,000kg, SLS block I is about 27,000kg hardly 3 times.

Orion does have improved rad hardening, but Dragon solves that issue with multiple redundant systems to compensate for radiation induced bit errors. The same approach being used on Starship

I was five days old on the day of the Challenger disaster. My mom always said between that and Chernobyl that spring she worried so much about her decision to bring children into such an uncertain world.

There was also an elementary school friend who was born on the day of the disaster, lost touch but I still remember him. Happy birthday Aaron if you’re reading this!

You're very welcome!

Yes, while on mushrooms, interestingly enough.

You may have misunderstood why SpaceX abandoned the Falcon heavy upgrade to the BFR. SLS is Rad hardened certified can get 59,000 pounds to Lunar orbit, well in excess of the SpaceX Falcon Heavy in full disposable mode to fast LTI Lunar Orbit by roughly 3x. SpaceX dragon is human rated only for LEO and is not rad hardened for operation beyond the van Allen belts due to huge savings in R&D test facilities, time, and costs. This is why SpaceX has been spending 7 years and billions on Starship and the Raptor program instead of BFR/Falcon Heavy tech.

Kepler 22b would like a word.

One of my earliest memories is of 7 red roses for the 7 astronauts on the altar in my preschool's chapel.

Ok fair enough. Still think it’s pretty clickbaity though.

It’s plausible that city could be grown in space as a vacuum is a good environment for spores and their makeup benefits greatly for space itself. Although it’s an enclosed system they have randomly grown in the iss before. If they can fruit then there’s mycelium and that’s what’s been used as a building material on earth already.

I read an article years ago about how they could colonize star systems in xx amount of years.

Here’s what I found w a quick google search on the subject

Human rating the Falcon Heavy and upgrading the Dragon capsule wouldn’t have cost close to $100 billion.

From the article (which was published yesterday):

>Reams of data needed to be analyzed by NASA’s teams to make sure that Artemis I didn’t succeed in spite of serious problems. Fortunately that does not seem to be the case: Although the teams are still working through the terabytes of raw data, the agency has pronounced the mission good enough to endorse its sequel.

From Wikipedia:

>The tenth mission for Challenger, STS-51-L, was scheduled to deploy the second in a series of Tracking and Data Relay Satellites (TDRS-B), carry out the first flight of the "Shuttle Pointed Autonomous Research Tool for Astronomy" (SPARTAN-203) / Halley's Comet Experiment Deployable in order to observe Halley's Comet, and carry out several lessons from space as part of the Teacher in Space Project and Shuttle Student Involvement Program (SSIP).

Why the fuck it this being posted 2 months after the mission?

> as long as OP is open to learning from those who have done the work to gain this understanding I don’t see the benefit in discouraging them.

Absolutely but that’s not what this was.

Also this isn’t the Ask Space Questions sub. There’s a weekly post for that and r/AskScience if you can’t wait

Tbh can anyone explain me what was the objective or mission of that space shuttle? I know nothing bout it
