SpaceX leads the space industry
Do you think Blue Origin will make a dent in their business?
@@SpaceNewsPod BO is too behind to make a significant dent in their busines that would put them on level ground with SpaceX. As with Boeing, if BO would stop crying about cost+ and quit spending $$ on lawsuits and such, both their reputations just might be partially restored. Elon's companies have brought such new ways to conduct business and make them profitable it'll be tough to catch up to SpaceX at this point. Even buying ULA, Boeing would just eliminate a 'competitor', not improve product. But it's nice to see BO posting on social media-at least a little!
I think that they are so close to landing the booster and getting the ship into and out of orbit. The camera views on this last ship were beyond incredible. Take care.
Thank you
Thank you for being thorough and knowing exactly what you are talking about.
The biggest win for each stage:
A successful Starship engine burn in space will mean future launches can go full orbital, start launching satellites even before they can return the vehicle.
If the booster can reach the water at 10m/s or slower, they can confidently begin testing Mechazilla as soon as they have a mostly-built second tower.
Nice to have:
Controlled descent of Starship, capturing tons of data; infrared cameras from inside would be great!
Pez door open and close.
Booster hovering while propellant runs out.
This year, I'd love for them to test a mostly empty booster, lift it off the pad and set it back down onto chopsticks.
Great content and well presented … Thankyou
Thank you, a great update as always.
Thanks Wil
The tower needs catching practice before anything comes to land.
How would they practice ? I don’t think they’d use a spare booster for catching. They will practice the move over water a number of times before trying with the tower. It seems like they will practice with a full mission. But then again, SpaceX has surprised us before
A hopper vehicle with folded legs and catch pins would land on legs to establish that known as a fallback. Then try landing the thing with full width but short, holding little (dangerous) propellant, between the mechazilla arms. If it doesn't work, fly off and land on legs, try again later.
The simple solution is a reentry module made to withstand reentry. Use a parachute landing. This could be preloaded at the anticipation of a conflict, quickly loaded on a special starship, lunched, ejected from the starship, reenter the atmosphere, and land. The starship goes back to the military base
Totally agree. Cargo modules autonomously re-enter and land. Any necessary orbital plane changes are part of the cargo kick-stage.
Starship goes home, fully and rapidly reusable.
I actually think FEMA would be a better costumer. Picture this. The year is 2053 and a category 7 hurricane hits Seattle ( let’s pretend that this global warming is a real thing ). All the roads and bridges are washed out and thousands of homes are destroyed. Scores of people have serious injury some life threatening. The calls go to a FEMA center equipment with 2 starships and 1 booster. Several modules are set up; Prestocked medical center/operating room, rescue and transfer equipment, infrastructure support equipment, food and water supplies, clothing , Tesla houses, …. Once the modules are manned by the people that will use them they are loaded onto the star ship and launched on the hour. The star ship is set on a ballistic trajectory to Seattle, deploys the module , then fires the engine to achieve orbit. The module enters the atmosphere, deploys a steerable parachute ( Spacex bought a chute manufacturer didn’t they ) and is directed to the coordinating starlink terminal. Elon will be a hero in Seattle, but in 5 years WOK society will prevailed, they will topple his statue , and direct mean tweets at him on X because he allows it
Successful landing is success for reusable. Successful orbital velocity is success for throw-aways!
Don't forget about the WB-57 observing the flight, and a dedicated Starlink observing the accent and decent of the Mission. Also the new heat shield system that they are currently developing. It's going to work. Double down on IFT4. Getting closer every day.
Another, SLS what's the progress on that slug. Just put it out of commission, and NASA dedicate more funds to SS. Just my thought.
Thanks for another great episode. Always enjoy it.

Shoot boy howdy, you are looking good! This move must be agreeing with you. Bright colored shirt on, shaved, great backgrounds and information with confidence to boot. :) Thanks for everything you do yo keep us informed.
I'm loving it! Thanks for the kind words!
You've asked for comments, so I'll offer my thoughts.
I believe these cargo delivery flights will use nonreusable Starships (throwaway cargo containers). If this is indeed correct, I'm further betting they burn the remaining fuel on re-entry, then blow the lower half (the engines and lower main tanks) and allow them to hit deep ocean and sink.
Blow the nose cone and upper tank (and allow this too to sink), deploy some form of parachute landing system for the remaining cargo hold, and land either very close to shore (and tow it in) or allow it to hit land and unload from the remaining cargo structure. Just my thoughts. Thank you. 🧐🤔
Deep ocean raptors will end up with china having raptors. I think a flight vehicle outfitted with minimal to launch and land once. Then a recovery team could come in and remove the raptors for reuse. Starship minus the raptors and empty I think is in the range of a helicopter can carry it back to the launch area. Alternatively, maybe they could fly in and build a simple launch stand refuel it and make a big hop back?
@@undertow2142 At this point, anything is certainly possible. As far as China goes, I'm sure they are already deep in the knowledge transfer aspect of things. Once Elon has all the bugs out and builds a fully working system, you'll soon see the Chinese building a clone. Guaranteed. Sadly, there are few secrets anymore.
Tricky! No booster, no return. Scrapping of proprietary technology would seem essential.
Point-to-point on Earth delivery requires a successful landing. Orbital delivery only requires successful orbital velocity.
Star ship can and will land up right on solid ground. If refueled it can propel itself into high altitude flite but not back into low earth orbit.
One more thought - if the military funds this why not have a beefed up ring of engines towards the top of the Starship (like the Lunar lander version) to allow landing and take-off from unprepared sites...
Forecast IFT4 NET 4 May 2024
I think a military version of Starship will have all the valuable stuff (engines, electronics) at the bottom, and some way (explosive bolts?) of easily detaching everything above. Then they just have to use a really big helicopter to take the bottom section to a ship, perhaps for eventual reuse. Or maybe they'll just destroy the whole ship after unloading their cargo.
That's a unique idea. I like it. If they scrap a whole starship, they will need to make sure they make enough money from the mission to cover the costs of a full build and scrap, which I'm sure they will because the DOD will pay whatever it takes.
Who or what decides the booster or ship is 100 above the ocean? Is there a autonomous radar altimeter connected to explosives at SpaceX?
Yes. There are various sensors in the booster and the ship that lets SpaceX track it precisely .
What makes you think that Starbase is the only place StarShip and its boosters can be built.?
Rapid scheduled disassembly solves the problem.😢
Seems like there are two scenarios here, ad-hoc and planned. For ad-hoc starship will fly a suborbital ballistic trajectory so presumably does not need heat shield tiles saving some weight. I wonder if you could limit the payload such that there would be enough fuel left for a return journey? Still problematic if no prepared launch pad though. Other scenario is to a prepared destination like a military base (Guam or Taiwan say). No reason why they could not have built a catch tower and refueling capability in this scenario.
Well. No doubt it's gonna be useful for moving things quickly for the Pentagon. But I ain't seen a cost comparison yet, so I'm not sure if it's gonna be too cheap. So, I reckon it's more likely gonna be used for really special cargo. And don't forget the value of insurance.
Yes, these Starship missions are kept very secret, as they should be. They probably won't release much information about the missions other than when they are launching and the video feed will cut off shortly after stage separation.
Nothing says it has to be a starship on top of the booster. Military wants the heavy lift and frequency of launches.
Tungsten Rods on top would be interesting to see
Starship will have to be able to land easily on uneven surfaces for a chance to land on the moon or mars
I would say 1 or 2 years till they start using it in the military I would guess to see if they can deliver equipment from orbit the giant keg from orbit :D
how long till they start using version 3 raptors? :D
That's the real question.
Elon will never allow his rockets to be weaponized,
They already have contracts with the department of defense. Including several Falcon 9 launches in the past and more coming in the future.
Elon will do whatever Uncle Sammy says when they wave the Benjamins in front of him. And no one will know for sure without the clearance necessary to know.
I wish we got more info about the results of the IFT3 tests that were performed. Seems weird to publicize it so much and then not even vaguely refer to the results. Not like spacex is scared of embarrassment or anything...
They released some data on their website. www.spacex.com/launches/mission/?missionId=starship-flight-3
@SpaceNewsPod that still just says that the tests were performed (or "initiated" for the prop xfer). It really goes out of its way to avoid talking about any results.
"Tricky"? I'm thinking "untenable". Starship is so far behind schedule that NASA may need to look elsewhere for a lunar ferry for Artemis. If the performance of IFT-3 is representative of Starship's in general, it has no useful payload capacity and should just be dropped. Even I have difficulty believing its design could be that deficient, but IFT-3 ran out of propellant on a suborbital flight carrying no payload at all -- where is all the delta v necessary to recover the booster and Starship intact as well as loft 100-150 tons to orbit going to come from?!?
In the long run , when elon achieves his goals he will just give the knowledge away. Count on it
decelerated?
