But right now they're waiting on an agency that's dealing with a record number of new launch vehicles needing licenses, but that is understaffed because Congress has cut their budget requests most years in recent memory.

(facepalm) Meanwhile Congress is funding SLS like crazy. Oh well...  >:(

I know right? I wish the dot product of useful progress and congressional priorities was better...

The printers are so slow they are building four of them? Why don’t they 3D print the 3D printers?

That that one step further; 3-D print the plant that 3-D prints the 3-D printers that 3-D prints the 3-D printed Tanks

A more personal telling of our origins before first launch. Fwiw, I care less about competition, more about cooperation and inspiring dozens to hundreds of other companies to make Mars + 🌎 multiplanetary society happen in our immediate lifetime.

Good article except click bait title.

How Tim Ellis went from wannabe screenwriter to Elon Musk’s biggest space competitor

As far launch competition goes they very long way down chain given not launch a rocket let alone reached orbit.
In order for USA companies
1) SpaceX
2) ULA
3) Rocket Lab which is very distant 3rd by mass to orbit.
4) Virgin Orbital
5) Astra one or 2 successful missions
6) Firefly reached orbit just.
7) ABL one failed launch attempt.

NG with Antares should be 3rd but its end of life.

When Terran R has few successful flights then  Relativity is serious competition until then they are just another startup but very well funded one.

It is unpopular to write anything negative here about Relativiy; the replies to this post will get lots of likes. But still, just for the records:

Relativity has a mind-boggling cashburn. Their current money reserves will be exhausted years before Terran R could actually launch to orbit. And I can't imagine that they will be able to raise the next billion bucks needed to become cashflow positive. Hard economic times ahead.

I will refer to this post when Relativity is bankrupt and Terran is history. Don't say noone warned you that something was wrong about this "printed rockets" story. It simply doesn't work.

It's not so much 'unpopular' but simply that others do not share your opinion.
Nor do they imagine 'billions' required for moving from a small launcher to a medium lift launcher using the same manufacturing technology, propellants, and engines (Terran 1 is switching to a single Aeon R for the first stage). And there are certainly parallels with another launch company that transitioned from a single-engine small launch vehicles to a clustered engine medium launch vehicle, for well under 'billions' (and Relativity don't to develop an ISS capable capsule at the same time).

They also have a flight vehicle sitting on the pad, and have been selling launch contracts for it in additional to contracts for Terran R. Companies they have built actual vehicles have proven to be pretty resilient despite sentiment to the contrary: Rocketlab continue to operate despite the purported dead-ness of the small launch market, Firefly have weathered 2 total funding failures, and even Astra is continuing to operate despite retiring their only launch vehicle. The graveyard of small launch companies is instead mostly made up of those who never manage to get to the building-a-flight-vehicle stage in the first place (e.g. Vector).

Yet there remain multiple new companies still in operation despite the presence of the 800lb gorilla. The 'proverbial air' has clearly yet to run out.

There is room for at least one other reusable launch provider. Blue Origin is the obvious contender but they’re effectively OldSpace in pace, so the others still have a chance.

Yes. A 2nd competitive, reusable launcher that arrives today will likely get sufficient business to be sustainable.

However, F1 reached orbit in 2008 and SpaceX only managed to reuse a booster in 2017. Operational cadence with reusable boosters really only started in 2018. That’s a decade to get from first flight to operational reuse.

Terran 1 is Relativity’s Falcon 1. Even if they cut the time from first flight to hypothetical, reusable Terran R in half, that’s 5 years to achieving competitive (and hopefully sustainable) operations.

5 years of expensive development and scaling that need to be funded. And that’s assuming everything goes really, really well between now and then.

There's room for a 2nd launch provider due to USAF's policy of keeping 2 US medium/heavy launch providers at all times, but there's no guarantee this 2nd provider would be a startup flying a fully reusable vehicle, in fact there're probably in-built incentives to award this 2nd contract to old space company.

The difference is SpaceX were facing the uphill battle of no booster ever having been recovered or reused, and exploring the problem space from scratch and identifying a lot of unknown unknowns.
Today, booster reuse is not a "maybe it might be possible" research project but a known quantity with multiple demonstrated working solutions. Likewise, SpaceX were doing a lot of internal training to get the staff needed to work on re-use, whereas Relativity (among others) have a large pool of experienced talent to draw from. e.g. the situation has gone from "so, how do we make a grid-fin that can survive re-entry?" to "hire one of the people who have worked on designing and operating re-enterable grid-fins".

Yeah. In 2008, SpaceX was still thinking of using parachutes for recovering Falcon 9 first stage. They didn't even switch to powered landing as their plan until mid-2010. They had to pioneer the field, with nobody in industry having experience. Ten years later, there are tons of ex-SpaceX, ex-Masten, and/or ex-Blue Origin folks with experience with VTVL powered landing. Acting like that doesn't make a difference in how fast a second-mover can get there is just silly.

That said, Relativity does still need to prove that it has what it takes to successfully build and fly a rocket. But if they can, I wouldn't be surprised at all if they couldn't duplicate at least first stage reuse faster than SpaceX did the first time around.

Hence my supposition that the path from Terran 1 first flight to Terran R operational cadence will be 5 years instead of 10 - which is half the time it took SpaceX.

Note Rocketlab Electron’s first flight was in 2017, and Neutron is now realistically tracking to, what, 2025 for first flight, so probably NET 2026 for anything approaching reuse at an operational cadence.

Seems to me that estimating 5 years from Terran 1 first flight to reused, operationalized Terran R is being fairly generous.

Part of a twitter thread on tomorrow’s launch that makes explicit that Terran-1 is very much a stepping stone to get to Terran-R and, depending on customer input, could be abandoned before getting to orbit:

Quote
All that said, as a customer-focused launch services company, we aren’t truly in charge of defining success for this launch. Our customers will really be our deciding jury. They may view this launch as a success once we prove the vehicle’s structural integrity at Max-Q, but they may also be looking to later stages of flight, like stage separation, and then 2nd stage engine ignition. The goal is to provide our customers with confidence in us and our abilities, especially with $1.65 billion in customer launch contracts already signed overwhelmingly for our larger reusable rocket Terran R, and billions more in our pipeline. Medium-heavy lift is clearly where the biggest market opportunity is for the remaining decade, with a massive launch shortage in this payload class underway.

https://twitter.com/thetimellis/status/1633148588137017359

Quote
If on our inaugural Terran 1 launch we encounter issues that are more commonplace with rocket launches – rocket science problems and not additive-related problems – we’ll ask those customers for input. Do they want us to continue down the path of producing more Terran 1’s to solve for those issues on this vehicle? Or, would like us to solve the remaining rocket science problems on the vehicle they are actually most interested in, Terran R?

They also have a flight vehicle sitting on the pad, and have been selling launch contracts for it in additional to contracts for Terran R. Companies they have built actual vehicles have proven to be pretty resilient despite sentiment to the contrary: Rocketlab continue to operate despite the purported dead-ness of the small launch market, Firefly have weathered 2 total funding failures, and even Astra is continuing to operate despite retiring their only launch vehicle.
None of those companies are close to making any money either, most are in a similar throwing-cash-into-a-pit situation to Relativity. You missed VO, who are at that stage and from public information have no more than a couple months, absent some miracle, before going defunct.

 A 'resilient' company is one that has a workable base for the future, not just one that hasn't gone bankrupt yet.
