SpaceX's rockets nearly broke even in its first full quarter as a public company, while its AI arm, mostly renting out computers, brought in four times as much
Swipe up for the story ↑Scroll down for the story ↓
SpaceX reported revenue of $14.6bn for July to September, 161% more than a year earlier and well above the $12.7bn analysts expected.
it brought in $1.8bn instead
Who is involved
SpaceX
the US company that runs the busiest rockets and Starlink, and now rents out AI computers; it reported the results
Who is involved
Elon Musk
SpaceX's founder and boss, who also runs Tesla; he announced the Starship catch plan and backed a merger
Why it matters
Watch whether the FAA approves the double catch on Starship's next flight, and whether the high price for renting AI computers holds, since analysts expect it to fall.
What's really going on
SpaceX is named for its rockets, but rockets are now the smallest part of its money.
What's really going on
In July to September its AI business brought in $7.6bn and Starlink $5.2bn, while launches brought in $1.8bn and only just broke even.
What's really going on
So the company that leads the world in launching things into orbit is now paid for mainly by renting computers to AI companies and selling satellite internet.
Why it works on people
Huge round numbers about the future, such as Musk's $500bn to $1tn a year by the end of 2027, pull attention away from the smaller real figures for the quarter just ended.
Who gains
AI companies such as Anthropic and Google
They rent computing power from SpaceX during a chip shortage, when chips are hard to get anywhere else.
Who gains
Elon Musk
He holds over 82% of the votes at SpaceX and about 20% at Tesla, so a merger could give him more control of the combined company.
Who pays
Tesla shareholders
If the companies merge, they would hold a smaller slice of a larger and more complicated business, one analyst told the BBC.
Who pays
SpaceX shareholders
The company still spends more cash than it brings in, and expects to spend $35bn to $40bn on buildings and equipment this quarter.
Nobody knows yet
Whether the AI rental money lasts.
Analysts at MoffettNathanson put the price of renting top Nvidia chips at about $10 an hour for the next few months, but only $4 later.
Nobody knows yet
Whether Starlink's subscriber growth beat forecasts or missed them.
Reuters says the 13.6 million subscribers beat the 12.19 million analysts expected.
Nobody knows yet
Whether Starship's double catch works next month.
SpaceX has never tried to catch the upper stage, which comes back higher and faster than the booster.
Nobody knows yet
Whether SpaceX and Tesla will merge.
The committees have not agreed terms, and half of all Tesla shares, not just those that vote, must approve.

Also seen in Tech, Climate and Gaming.
AI companies are paying so much to rent computers that it is now most of SpaceX's money, and the makers of grid equipment have doubled their orders.

SpaceX's shared ride carries 32 payloads
Swipe up for the story ↑Scroll down for the story ↓
A Falcon 9 launched Bandwagon-5 from Cape Canaveral in Florida on Tuesday, a day late because of bad weather where the booster lands.
Bandwagon is a shared ride: a small satellite of up to 50 kg flies for $350,000, far less than a whole rocket.
The 32 payloads included SpaceX's second Starfall capsule, built to bring goods back from orbit.
Varda's W-7 capsule carries a test of a cancer medicine, to see whether weightlessness helps it dissolve better.
Why it matters
SES and Planet put up a test radio to pass data between satellites at different heights.
Why it matters
Shared rides are how small companies reach orbit at all, which is why SpaceX's plan to end Transporter matters to them.
Good news
A Falcon 9 booster carried 32 payloads towards orbit on Tuesday and then landed on a ship at sea, after its 19th flight.

Xona's navigation satellites reach orbit
Swipe up for the story ↑Scroll down for the story ↓
Xona Space Systems, a California start-up, launched six satellites on SpaceX's shared ride on Tuesday, SpaceNews reports.
They let it start showing its navigation and timing service working as a group.
Xona plans about 250 satellites as a paid alternative to GPS, the positioning system the US government owns.
Its satellites fly closer to Earth than GPS ones, so Xona says its signal is at least 100 times stronger.
Why it matters
Almost every phone map and ship finds its place from GPS, which one government runs. A stronger second signal could get through interference that blocks weaker ones, NASASpaceflight reports.
How it works
Why a rocket company builds its own engines
How it works
An engine bought from someone else arrives on their schedule and at their price, so new rocket makers build their own and pay more at first.
How it works · step 1 of 5
A rocket's engines are its hardest and costliest part
How it works · step 2 of 5
Buy them, and the seller's delays, prices and politics become yours
How it works · step 3 of 5
Antares, the last new US mid-size rocket, flew on old Russian engines
How it works · step 4 of 5
So new rocket makers build their own, paying more and waiting longer at first
How it works · step 5 of 5
Then they set their own dates and costs
The twist
Building your own engine is slower and dearer at the start. It is also the only way to stop another company deciding when your rocket flies.
The picture
Antares flew on Soviet-era engines and a body made in Ukraine. All four mid-size rockets now being built in the US use engines their makers build.
Seen the same day
All four new mid-size US rockets use engines their own makers build, the lesson Ars says they took from Falcon 9.
Seen the same day
Reaction Dynamics built one engine of its own for both its rockets, and says Canada wants a rocket it does not have to buy from the US.
Seen the same day
Ukraine relies on a link another company runs, so the decision to slow it was made somewhere Ukraine could not see.
Seen the same day
Xona is building a second navigation signal so its customers do not depend only on GPS, which one government owns.
The catch
Building it yourself can also be the cause of delay: Rocket Lab's own engine and its own carbon-fibre tanks are part of why Neutron has slipped to 2027 or later.
The whole
Most people depend on parts of space they never chose, like the GPS signal in a phone map or a satellite link a soldier uses.
The whole
They usually find out who controls it only when the owner changes the terms.
Nobody knows yet
How many satellites Xona actually put up on Tuesday.
SpaceNews says six.

Senators ask SpaceX who slowed Ukraine's link
Swipe up for the story ↑Scroll down for the story ↓
Four US senators from the Democratic party wrote to SpaceX on Monday about the slowing of Starlink for Ukraine's forces from 12 to 14 October.
They asked what part SpaceX played, who made or was told of the decision, and who can cut Ukraine's access.
The Wall Street Journal reported, citing unnamed US officials, that Musk personally ordered the slowdown, the Guardian says.
Musk says the US government sets the limits on Starshield, the military version of Starlink, and the Trump administration denies limiting it.
Why it matters
Ukraine's drone units and missile warnings lean on the link, the senators say.

Relativity Space, a rocket company in Long Beach, California, said last Friday that the upper stage of its Terran R rocket passed its first full test firing.
Terran R is one of four US rockets being built for medium loads, the size Falcon 9 carries, which SpaceX plans to stop selling to others.
Ars Technica, a technology news site, guesses Stoke's Nova will fly first, in July 2027, then Terran R in September.
It expects Rocket Lab's Neutron in 2028 and Eclipse, from Firefly and Northrop Grumman, in 2029 or later.

Canadian start-up plans a bigger rocket
Swipe up for the story ↑Scroll down for the story ↓
Reaction Dynamics, a start-up in Quebec, Canada, unveiled Borealis on Tuesday, a rocket meant to lift 6,000 kg to low orbit, first flying in 2031.
Its smaller rocket, Aurora, would carry about 200 kg and aims to fly late in 2028.
Last year it swapped a part-solid engine for an all-liquid one that both rockets can use, and has test-fired it 21 times.
It has raised about CDN$50 million and says Borealis needs more than CDN$200 million more.
Why it matters
The company says Canada wants its own way to launch rather than relying on rockets from the US.
Why it matters
It also wants the small satellites that would be left looking for a ride if SpaceX ends Transporter.
How it works
Reaction Dynamics built one engine of its own for both its rockets, and says Canada wants a rocket it does not have to buy from the US.

Reaction Dynamics
If SpaceX ends Transporter, its shared ride, small satellites will need another rocket, and the Canadian company wants to carry them.

Astrolab, a California company, will send its FLIP rover to the Moon's south pole later this year on Griffin-1, a lander built by Astrobotic.
FLIP carries Spaceborne Computer-4 from Hewlett Packard Enterprise, the first powerful computer and graphics chip to be tried on the Moon.
It will run a program from NASA's JPL laboratory, first used on Mars, that finds the rover's place by matching the ground around it to a stored map.
The Moon has no GPS.

The US State Department has started Project Constellation, a $5 million, two-year effort to link countries new to space with US companies.
The US mission to the international bodies based in Vienna announced it at the US Space Forum last week.
Meridian International Center will run it, with the Commercial Space Federation and a policy firm called SPACEAIMS.
It aims at more than 70 countries, and at how they vote at the UN committee on peaceful uses of space.
Why it matters
It is the US State Department's second such plan in two months, after $6.5 million in September for satellite internet in rural southern Peru.

Volunteers hunt the galaxy's hidden black holes
Swipe up for the story ↑Scroll down for the story ↓
Astronomers at the University of Southampton in the UK want volunteers to search data from TESS, a NASA space telescope, for hidden black holes.
They estimate the Milky Way has made more than 10 million black holes, but only about 70 have been found.
When a black hole passes in front of a star that orbits it, its gravity bends and brightens the star's light for a moment.
Computer programs often mistake star flares for them, so people check the data by eye.
Why it matters
The project, Black Hole Hunters, has had nearly 23,000 volunteers since 2021.
Good news
Nearly 23,000 volunteers have joined Black Hole Hunters since 2021 and made more than 12 million checks of telescope data, helping astronomers search for black holes hidden in our galaxy.

Halley's Comet dust lights up the sky
Swipe up for the story ↑Scroll down for the story ↓
The Orionid meteor shower peaks overnight from Wednesday into Thursday, with up to about 20 shooting stars an hour under a dark sky.
The meteors are dust shed by Halley's Comet, which last came near the Sun in 1986 and returns in 2061.
The grains hit Earth's air at about 66 km a second and burn up.
A bright Moon will hide many, but it sets early on Thursday, leaving dark hours before dawn.
Why it matters
Earth crosses Halley's dust twice a year, so the same comet also gives the Eta Aquariid shower in May.

A team led by Nicole Ford at McGill University in Canada used the James Webb Space Telescope to study gas near Sagittarius A*, the black hole at the centre of the Milky Way.
Astronomers call every element heavier than hydrogen and helium a metal.
The study is published in The Astronomical Journal.
Why it matters
This black hole swallows far less gas than giant black holes in other galaxies.
Why it matters
Metal-rich gas cools and falls in more easily, but 1.8 times the Sun's share is too little to speed that up much.
