I don't recall reading or hearing about FAA mishap investigations and reports after unsuccessful attempts to land the Falcon 9 boosters. Did the government still require investigations and reports, and we just didn't hear about it? Or were these events considered simply unusually spectacular "splashdowns" of expendable rocket stages, no reports required?

Just curious…

I think it was Asimov who said that considering the countless number of events that occur every day,it would be much much more suspicious if there were no coincidences.

Scott, I found it a bit presumptuous to say only you all in the States will be able to witness the "American Eclipse " We get our fair share of clear skies, too, if you were unaware.

Some classical illiterate during the Apollo Program had them using pericynthion and apocynthion for the orbits around the Moon. Those would have been tolerable if they had spelled them pericynthian or pericynthiēn and apocynthian or apocynthiēn, but all NASA publications used the -on spellings. These names refer to nicknames that the Greeks had for the twin gods Apollo and Artemis, the gods of the Sun and Moon. These twin gods were often called Phoebos and Phoebē, which referred to their bright light. The more obscure nicknames derived from their birth on the highest point on the island of Delos, on Mount Kunthos, Cynthus in Latin. Anyone who has visited Delos knows that there are barely any hills, never mind mountains on the island. That pair of nicknames was Κυνιος and Κυνιη, typically spelled Cynthius and Cynthia by the Romans who reserved K for words borrowed by Etruscan and substituted Latin noun declension endings for the similar Greek endings. So even if NASA was intentionally making a reference to the god Apollo they should have spelled the words pericynthiun and apocynthiun in the Latin spellings adopted into English. Phoebē and Cynthia are still popular girls' names because they sound nice. Why the final letter of Phoebē is pronounced ee, while that of Cynthia is pronounced a is lost in the mists. Selēnē was another nickname of the Moon, and is cognate with the Latin luna as the most common word for the Moon. The most logical words for closest and farthest distance from the the Moon should therefore be periselēnēn (or periselēnan) and aposelēnēn (or aposelēnan). -ēn should be pronounced -een in most modern European languages, and the emphasis should be on the penultimate syllable (-lē-) because the final syllable is long. The reason an -n is added is because the Greek prepositions peri "close to" and apo "away from" both take the accusative case, which was also used for the direct object of verbs. The endings in -an are also acceptable because most Greek words were imported into western languages via Latin, which regularly substituted a in the endings of first declension nouns that in Greek used η (ēta), because Latin first declension nouns used -a. So pronounce them pereesel ee nan and aposel ee nan.

Weird question (that you might have been asked a million times before).

Is it possible to take a space craft that has been inactive for a while (like the space shuttle) and reactivate it for space flight safely, like some people can do to cars that have been lying around for like 20 years or so?

8:34 Scott Manley should just smile and add that which he misspoke to the Bloopers reel! It's easy to make a mistake in terminology, the smart presenters simply explain it and move on! The rest of this video was of extremely high quality in nearly all of it. Everyone makes mistakes, smile, you're on camera! From Google: "To err is human to forgive divine." I probably mis-transcribed that somewhere, don't worry I'm as human as any other person that errs! 😁📹

Apparently the Vandenberg SpaceX launch was visible from near the Utah/Colorado border. Just off the horizon. (I might be in Fredericksburg as well, but traffic and/or weather might result in a deviation. Coming in from the West might reduce the traffic issues.)

Drink Quafe, fly safe.

Corona Borealis? At this time of year, at this time of day, in this part of the country, localised entirely within your kitchen?

Always interesting

Scott, FYI, SpaceX said on stream the propellant transfer was successful.

No mention of ABL Space? Their launch (#2) comes up pretty quickly. My office overlooks Wallops Is. (MARS), and I found out my neighbor is LD (Launch Director) for ABL, he's in Kodiak right now, leading the charge! Praying for success for them this go around, another up and comer, eh?

Evidently pretty high since it actually happened…

Great, as usual, but only your back ground shelf is in focus?

Stupid eclipse. April 8 is my birthday and I always go to Fredericksburg for it, this will be the first year that I'm not because all the hotels are several times the price they used to be. I hope whoever got me this eclipse kept the receipt so I can return it.

If you look inside the rocket 🚀 theres smoke inside 😮 maybe a bad battery 😊

Pretty huge, when looking whole multiverse theory. (if alien spacecrafts (possible ones) are included) 😀

What if Falcon could refuel and liftoff from the barge ?

Odds are good they will never succeed with starship..

I got this from the horses mouth since this year SX has lost 2 teens from 213-219 million. And NASA has budget concerns? Of course Musk is launching military hardware into space he wants those subsidies which he has been receiving besides what people think since Tesla than his failed tunnel company where through subsidies actually ended up making money when the door was finally shut. Every starlink launched he directly receives money from our government and I wouldn’t be surprised if other nations also pay stupid amount of dollars

Oh man exciting about the eclipse! Long time viewer of both you and Tim and we'll happen to be in Fredericksburg as well. I'm sure there's a thousand places people could be, but we're going to be at an RV park there. Here's hoping for great weather

Strictly speaking, Starship was at orbital SPEED, but not at orbital VELOCITY.

Where are you going to be in Fredericksburg? I’m flying into Austin on Saturday to take photos of the eclipse. I have a parking spot in Kerrville but could divert to Fredricksburg.

13th is not a lucky number for me, either. Had a daughter born on the 13th, became a lawyer. Was hoping she would turn out decent, but nooo.

For eclipse travel, fly into a city a 2-3 hours a way and rent a car. Will be cheaper and will permit you to drive to a good weather location if necessary. A 3 hour event in a 16 hour day leaves lots of time to drive on that day.

It's amazing that voyager is even alive let alone able to communicate with its 1970s computer….

So that’s what millions of US taxpayer dollars looks like burning up…good to know. When, not if, MuskX can’t deliver on its contract for HLS and goes bankrupt heads will roll for letting this disaster of a program go on like this. Honestly three test flights and they can’t control their rocket? Can you imagine if SLS blew up the first three times?

Re your thoughts on IFT3 and steering fuel running out, please do a parallelism comparison with the Columbia shuttle disaster.

In it, during reentry, yawing jets were working, to compensate for the extra drag of the holed wing, working so smoothly that the astronauts never noticed them firing. Then the fuel ran out, and the fatal tumble started.

A safety issue is the current standard of hierarchical displays found on planes and spacecraft. There was a display for the yaw jets on Columbia, to monitor fuel level, but one would have had to drill down several layers below the default display in order to see it. SOP did not call for its monitoring. The fatal tumble came unanticipated.

(Part of me still yearns for the old aircraft analog-guage displays that are always 'on'.)

Elon had a choice … he could have developed an upgraded Falcon 9 with 9 Raptors. This would have increased payload from 20 tons to 50 tons with lower development cost & risk and shorter schedule than the starship. But Elon is going for economy of scale (size) and a reusable 1st stage for the best cost per pound to orbit.
In 2025 China is scheduled to launch a Falcon 9 equivalent using meth-lox engines. I expect China to launch a follow on generation with 2 or more strap-on boosters and a reusable upper stage 5 years from now. This will quickly get them close to starship performance.

Never tell me the odds.

has elon made the proposal to rename the launch facility at boca chica to "Sun City" yet? 😂

Apophis passes earth Friday April 13th. It´s fine. We´re fine. We´re fine right?

"…but this is way cooler." is almost an understatement…… and I'm such a child.
Watching the return someone said "we still have telemetry because it's puching a hole in the plasma is creating". I was bobbing in the chair laughing like a toddler.

I did not know that gravity on the moon was lumpy. Didn’t even know that was even possible. That could be a video on its on. That must be a huge complication depending on whatever planet or moon. What other objects have lumpy gravity and how is that determined?

22:18 Do you know something I don't? What do you mean the odds are bad that we'll have clear skies to watch the eclipse in Canada? I'm expecting it to pass right above my head, and so far long term forecasts looks good.

20:45 Gilmore space has the first Eris rocket fully assembled at the pad.

11:55 it was the third year of the war..
Belarus and Russia attacked Ukraine..
cringe

Great video, Scott…👍

My preferred terminology when describing the elements of a lunar orbit in a lecture is to say "Apolune" and Perilune". I find these more fun to say when lecturing than "Apoapsis / Periapsis" or "Aposelene / Periselene."😉

The Starship tumbling reminded me of Neil Armstrong in Gemini 8, in which Gemini docked with Agena and also began tumbling. Armstron eventually undocked as the Gemini continued to tumble. Armstrong used the RCS to bring Gemini under control and renter the atmosphere as it safely splashed down. It was determined the Gemini's attitude control thruster malfunvtioned that caused the cemini and Agena to tumble, which was remedied by undocling and RSC. Its one of my favorite space stories.. well, that and the SCE to AUX. Thx for the video, Love these updates!

Scott, I'd like to see you do a brief account of your bookshelf.
