Starship is not yet reusable but they have the MVP and a fantastic position to iterate forward.

-- they have an orbital launcher with the largest diameter cargo bay

-- larger sats have bigger antennas and bigger PV area and more bus power. this scales as diam^2

-- 26 x Starlink v3 ~40-65 tons to LEO

-- every launch generates revenue, locks out the orbit for competitors.

-- they can launch more volume, more mass and cheaper than anyone else by a large margin

-- the design is validated - things will work

-- there is technical debt, issues but the rocket did the job

Caveats

-- timelines for full reusability are optimistic etc

-- there will be other issues in scaling to launching gigawats into orbit

-- cooling will have to be

-- Musk might go Full Villan mode before the thing works

[meta] I really didn't like that other negative comment getting voted to the top. Looks like it's made by someone who never worked in a bigco. For every bigco I worked, at any time there were hundreds if not thousands of open issues. You could list them and try arguing the company is about to fail and you'd scare people who don't know better.

It's the judgement of the severity of the issue that matters not #no_of_issues. And if there were 0 issues would our job exist?

The issue is that there is ultimately a limited market for having access to space. SpaceX's business model is premised that if you make access cheap enough that there will be a market for multiple launches a day. But to me demand seems very finite? You can make it 10x cheaper or 50x and it sort of doesn't matter.

There just isn't much to do in space. You have:

- Telecommunications.. Can scale only so much. Starlink is cool. Compared to Iridium it's way way cheaper. But demand is .. modest? It seems to only beats fiber on the ground in special situations

- Telescopes looking up. This is limited by science budgets that aren't going to change much.

- Telescopes looking down. Those people have infinite budgets and already have all the satellites they'd want. If you're not in NATO then can't depend on SpaceX anyway - so they're not capturing that market.

- Tourism. Vomiting for several hours in zero-G will be a thrill for some for a bit, but I don't see this being a huge industry. Maybe on par with basejumping or something.

- Mining.. seems impractical scifi.. premised on wanting to build huge structures in space - but again, for what goal ultimately?

It's sort of like if you made access to Antarctica 100x cheaper. It'd be great, but it's hard to imagine it's going to suddenly open up a ton of demand.

But I'd love to hear counter arguments :)

Indeed SpaceX is boiling multiple oceans at the same time and betting the timing will align.

-- SpaceX is building a starship factory, not just starship. The market won't deliver enough demand, they need to create their own

-- V3 Starlink constellation targets 100k sats. With 50 sats per flight (100t to orbit) you need 2000 flights to build constellation and then 400 flights per year to replace sats after 5y lifespan.

-- There was that idea of ballistic human travel but this is unlikely to materialize

-- There also was solarsat/powersat where solar power is beamed from space and if you massaged your math the right way the numbers were ~promising

-- AI saves the day. We "need" 1mln AI sats. That solves the demand and justifies the spending. for now

the demand for bandwidth is infinite… this used to mean copper -> fibre, but it’s that squared for orbital bandwidth, as they lower and close up the sat formation, the antenna gets smaller and the data rate gets faster … I think Musk killing all terrestrial telcos is quite likely

It is not designed to compete with finer. Go somewhere truly remote and see how it’s changing the world very quickly. I’ve seen it first hand in Arctic Canada, Australia and North Africa. Before starlink the best they had was dialup. Now they video chat family and doctors, do school online and so much more. Easily a few billion people will use it.

You also forgot about AI data centres in orbit, on which SpaceX have pegged virtually all their valuation in.

I swear to God LinkedIn would describe taking a shit in a public park this way. The West Coast is out of their damn minds.

rkagerer2 days ago
Could you elaborate on your counterpoint?

Genuinely interested. How does or doesn't an existing satellite constrain other operators from desirable orbits? Is it irrelevant because many satellites can share the same orbit at different phase angles (i.e. satellite train), and there are more than enough similar orbits to go around? How many spacecraft would it take to actually be a concern (accounting for attrition from end-of-life ones going out of service, and the point of crowding where diminishing spatial/temporal buffers available for the collision avoidance adjustments needed to practically maintain your desired orbit become too risky).

The biggest issue is payload. Right now they’re launching with very light payloads, way less than the Saturn V or even the Falcon. Definitely short of their goals. They’ve never demonstrated a real payload weight. Until this happens their progress is illusory and a skeptic would claim their engines can’t take a real launch payload weight.
ggreer2 days ago
Today's launch was the 3rd largest payload ever put in orbit (52 tons). Only Skylab (77 tons) and Buran (80 tons) exceed it.
Polizeiposaune2 days ago
The Starlink V3 sats launched today are much bigger and heavier than the Starlink satellites they've been launching on Falcon. Even if they fit within the Falcon fairing, they'd be too heavy to launch on F9.

> skeptic would claim their engines can’t take a real launch payload weight.

full duration full throttle burns of Raptor3 are common and I'm pretty sure a part of qc for each new engine anyway. Payload weight doesn't strain the engines, once they're throttled at 100% then they're throttled at 100% no matter how much or how little payload there is.

Their engineers understand mass, and how to distinguish it.

Is nobody concerned about putting things in a ship that explodes every other time they launch it
jfoster2 days ago
Falcon 9 used to do that when being tested.

They push them to the limits in testing/development to make them reliable in production.

Starship still in testing/development.

dwaltrip2 days ago
The exploding rockets were all test launches. SpaceX is pretty good at launching rockets successfully:

> Rockets from the Falcon 9 family have a success rate of 99.57% and have been launched 703 times over 16 years, resulting in 700 full successes, two in-flight failures [...], one pre-flight failure [...], and one partial failure [...]. The active version of the rocket, the Falcon 9 Block 5, has flown 633 times successfully and failed once [...], resulting in a 99.84% success rate.

When I made this comment I was unaware that this most recent launch had in fact also ended in an explosion.

I guess the next defense will be it only exploded after safely delivering payload

fluidcruft2 days ago
Probably, but I assume it would depend on price differentials and payload. Something like constellations of multiple identical satellites could plan to tolerate losses. One-offs like space telescopes not so much.

No, and if you are you’re not familiar with how SpaceX operates.

Distillation: Stream starts in about 1hr. Payload is 26 starlink v3 satellites.

Launch window is 8:15 AM to 9:30 AM eastern time.

Superheavy will land 7min after launch. Starship lands 9hrs post launch.

Edit: Both will be splashdowns (originally said they'll be caught)

billfor2 days ago
The live channel has some video of recovery of the last starship which is pretty cool - it remained floating so they crawled up and removed some of the tiles to see how they performed, and actually reinstalled a few of them for the upcoming flight. So this mission will actually see some of the tiles flying for a second time.

> Both expected to be caught by chopsticks. Will be a first for Starship.

SpaceX's flight profile says both are splashdowns?

prodigycorp3 days ago
Article must be wrong.

  > During operational flights, SpaceX plans to bring both Super Heavy and Ship back to the launch pad, where they'll be caught by the tower's "chopstick" arms. The company has already done this three times with Super Heavy but has not yet attempted it with Ship.

F9 fits how many?

>>Payload is 26 starlink v3 satellites.

>F9 fits how many?

Zero. Starlink v3 is too big for the F9 payload fairing. It's not just a matter of mass, the diameter and overall volume is important as well. In terms of performance, last I read they're supposed to add 1 Tbps of capacity each, so assuming they all work the first time all 26 would be around 10x the network addition of a full F9 v2 Mini launch. But the larger antennas would have other advantages beyond sheer bandwidth, and they'll be able to start getting more serious about direct to cell.

Good4boothee2 days ago
29 v2 satellites (around 4 times lighter than v3)
billfor2 days ago
I think somebody on the livestream said 60x capacity over Falcon.
motionlessveloc3 days ago
Ship will also have to be outfitted with a life-support system ahead of crewed missions, which could be coming relatively soon. For example, NASA picked Ship to the be the first crewed lunar lander for its Artemis program, which aims to land people on the moon for the first time in 2028 on the Artemis IV mission.

Don't worry, there is absolutely no chance this will happen in 2028. There are many detailed takedowns of why the "Human Landing System" schedule is preposterous, but here's HN's idlewords:

There is (2 minutes before Flight 14, maybe it changes in 10 minutes) low chance, but not no chance.

> This would be an ambitious but achievable cadence for Starship, particularly if the tanker Starships didn’t have to be reusable, and could be made without a heat shield or control surfaces. Just how much time SpaceX has to reach this cadence is an interesting question, since right now NASA and SpaceX are locked in a game of chicken around who can commit to the least realistic timeline. But it probably has to get in gear by early 2027.

This is good evaluation. A launch every week in 2027 is ambitious, but not impossible.

tonyhart72 days ago
"A launch every week in 2027 is ambitious, but not impossible."

I don't think a week is enough to gather data and fix subsequent launch

What an incredible feat of engineering, even if it doesn't make orbit. Just getting that much mass off the pad is mind-boggling.
GuB-422 days ago
It certainly is, but my mind is more boggled by the Saturn V that did it 60 years ago. Space launch technology feels like it had a 30 year gap, as in, nothing significant happened between the Space Shuttle and the Falcon 9. And now, we are just catching up. Not just SpaceX, there is also Blue Origin, Rocketlab,... and everything that's happening in China.

An by the way, the whole point of Starship is not just doing it, it is doing it cheaply (by space standards). The whole reusability thing is part of it, and so is the "assembly line" approach that lets SpaceX treat their experimental rockets like fireworks. If the goal was just to lift a lot of mass off the ground, it is not even a great design, reusability in particular is costly in terms of payload capacity.

Gareth3212 days ago
It's incredible to witness what humanity is capable of when pushed to our limits and appropriately motivated. The space race was in many ways a civilizational and existential fight for the U.S. The innovations this spurred in a relatively short span of time (and the risks the astronauts took) are numerous and impressive. I sometimes wonder that if in the absence of adversity, humans tend towards comfort and security and stability. Maybe that's obvious. Maybe most people with full bellies, warm homes, and physical security just aren't motivated to work 16 hour days for years on end and risk lives.

I suppose we should be grateful that SpaceX has found and collected enough of these crazy people in one place on this mission.

Schiendelman2 days ago
The reusability is what made the rest of these investments possible. Musk is annoying, but you have to give him credit for it.

"nothing significant happened between the Space Shuttle and the Falcon 9"

well US government found new toys (proxy war) instead of space

cameldrv2 days ago
If you get the chance to see it in person, it's an experience. The best way I can describe it is that looking from Isla Blanca beach, it looks like a skyscraper sitting on the pad, and then, the impossible happens -- the skyscraper lifts off into the sky.
benj1113 days ago
Well considering the point of it is the make orbit, it would be a bit useless if it didn't.

Would HN describe a huge program that didn't do the thing it was designed to do a "feat of engineering"?

s081486923 days ago
Yes. The Starship program is pushing the limits of engineering, if it fails today it doesn't make it unimpressive

I'd also consider the attempts at fusion energy to be very impressive engineering projects even though none have them have yielded a stable source of fusion energy

bonesss2 days ago
Blowing something up so hard it almost gets into space is a feat of engineering, even if all it does is rain debris from ahigh.
Symmetry2 days ago
They seem to have reached near-orbit with one vacuum engine failing. Lets see if they decide to go all the way to orbit or if the failure causes an abort.
thomasfromcdnjs2 days ago
Confirmed, orbit!

Hell yeah, that was the longest 10 minutes.

motionlessveloc2 days ago
Abort confirmed :(

Update: Or maybe not? They're reviewing the status now.

Update 2: Go for orbit!

Update 3: Orbital insertion complete!!

Update 4: First Starlink satellites successfully deployed!

billfor2 days ago
What was interesting is how short the single engine burn was to bring it from suborbital to orbital. It was just a few seconds. I'm not even sure I saw the altitude change.

jve2 days ago
> near-orbit with one vacuum engine failing

near-orbit was planned, they just had to burn longer. It's in the timeline: https://www.spacex.com/launches/starship-flight-14

But yeah, they had a big decision to make in those few minutes between engine cutoff ang insertion burn.
