As far as CST-100 destinations are concerned, I wouldn't look to Bigelow. Bigelow Aerospace is a dodgy company run by a UFO nut. https://en.wikipedia.org/wiki/National_Institute_for_Discovery_ScienceJob sites that do employee submitted reviews trash the company, its micromanaging CEO, the constantly changing directives. https://www.glassdoor.co.uk/Reviews/Bigelow-Aerospace-Reviews-E373179.htmI think it's scary that the ISS is about to host a Bigelow module (assuming CRS-8 success). CST-100 shouldn't bank on a Bigelow station to expand its flight rate.
Bigelow may have its problems, but name-calling the owner as a "UFO nut" doesn't afford your comment any brownie points since (1) this was originally NASA technology and (2) no other company has yet to offer any options other for a continuous space presence--not even Boeing, which built several of the ISS modules.

It would be hard to outdo "falcon full thrust" in the silly name department. And at least Musk got the message that calling your baby the v-2 was not a great idea...Supporting two providers is essential. There is no competition if there is only one provider. That has been the history of spaceflight to date: simple monopoly where "reliable access" was the goal, not cost competitiveness. But that is changing, by necessity. Simply swapping one monopoly (ULA) for another (Space X) makes no sense. The result would be the same. Now, with the this work aimed at creating a private crew flight industry, the next few yeas will be telling as ULA brings new capabilities on line, new providers surface, new partnerships are forged, and the industry develops. Also, We shall eventually get to see the real costs for Space X, instead of the subsidized loss leader launch prices kicked around publicly at this point. Just like in every other business, there is no "permanent" winner to be crowned, and even first-to-market is no guarantee for market winner, the race is never ending and each entity has to prove and reprove itself continually.
We all know that there are applications for he Commercial Crew spacecraft beyond the ISS
Try reading the full thing. The comments were a response to the question of "how does funding two providers result in competition if one is priced higher?" Short answer was (and is): giving it all to a single provider becuase they claim to be cheaper (for now) or will deliver first simply results in just another monopoly. It is factual; the goal is creation of a situation that leads to ongoing competition. Thus, two provders needed. And the point remains valid that SpaceX prices for now are whatever Musk says they are: he answers to no shareholders -- and a lot of doubt exists that those prices will get them to a profitable situation. Undercutting price as a startup strategy is nothing new. Ask Jeff Bezos.
...and a lot of doubt exists that those prices will get them to a profitable situation.
We all know that there are applications for he Commercial Crew spacecraft beyond the ISS, such as Bigelow stations and space tourism. But Dragon 2 is significantly cheaper than Starliner. How can Starliner compete in the industry after ISS is deorbited?

Look at Amazon.com and how long it had to wait to achieve a record of proven profitable quarters -- yet it had money available for acquisitions and all sorts of development. This is true in many industries, especially emerging ones or those using new business models/
If they were losing millions of dollars per launch, the reasonable thing would be to keep their money in the bank.
...Now beyond LEO things start to look a little more even as the separate service module would allow them to easily add more capability without as many changes to the reentry vehicle.

A BEO version of Starliner would probably be substantially different from the current one.They'd also need to fit solar panels or something on there, batteries aren't gonna cut it. Easiest way would probably be a separate propulsion module that can be ditched in an abort (along the lines of this http://www.russianspaceweb.com/images/spacecraft/manned/soyuz/soyuz_acts_fregat_1.jpg). Or use ACES? After orbital refueling it should have plenty of fuel left for lunar orbital insertion, then separate Starliner to do the rest of its mission
Now that the Boing build X37b is going to fly on F9, what are the chances for CST 100 to also try a flight on F9? Is it hardwired to Atlas V, or can use other launchers? The reason? Similar to USAF, NASA may want to have more options avaliable, especially if Vulcan is delayed or does not materialize at all.
CST 100 and Dragon 2 are supposed to provide redundancy. That's why they launch on different rockets. There's no point in putting CST 100 on Falcon.

One thing, I have been wondering about is if the CST-100 can easily be upgraded in order to be used for crewed transportation to the deep space gateway?

>Boeing's plan calls for the first two launches to be on an Atlas, but the company has not ruled out other launchers, including the Falcon 9 developed by CCiCAP rival Space Exploration Technologies (SpaceX). “It's got to be compatible with others and we continue to have discussions with SpaceX because once the Falcon 9 has enough flights under its belt and is safe enough to fly crew, we feel we can make that business decision. We'll be going over [to SpaceX] soon to see what it will take to make sure our new vehicle is compatible with the Falcon 9. If the price point stays extremely attractive then that is the smart thing to do.”>

Starliner has lot of potential for doing LEO tourism flights, this may only a be few hours orbiting earth before returning. Need to start somewhere plus it would test tourism market for space hotels.With 10 reuses per capsule and 6 month turnaround time, Boeing only needs small fleet to support 10 missions a year. If they could sell 5-10 missions a year, mission costs would come down. Bulking buying service module components ( mainly engines) and LVs should give them significant discounts.
I'd want to know how I'd react to zeroG before committing $30m to day in space.
ISS trips involved an extensive training course. Some rich tourists might be interested in giving up few weeks to train as astronaut but most couldn't spare time. I think there is market for day trips to LEO. How big Boeing or SpaceX will likely find out on next year or two.Training may include a couple of suborbital trips in NS or SS2. I'd want to know how I'd react to zeroG before committing $30m to day in space.
One day trips are problematic due to weightlessness acclimatization time varying between people. Some people need 3 days. If you are vomiting all day, that kinda spoils things. Not sure how one would predict reactions based on suborbital rides or vomit comet runs.

But their Commercial Only Version can seat 9 people. So with Vulcan or F9 and 9passagers they could be competitive
Quote from: Tomness on 08/21/2021 07:02 pmBut their Commercial Only Version can seat 9 people. So with Vulcan or F9 and 9passagers they could be competitive? Per Boeing, max 7, not 9.edit: p.s. If both are max 7 pax-crew, then advantage would still go to Dragon on per-seat price, all other things equal. Of course, neither has built such a configuration as far as I know, and we don't know details of the margins-constraints for a 7-seat configuration of either (e.g. ECLSS, down-mass limits, etc.).

One thing that concerns me about Starliner for space tourism is the free flight endurance--sixty hours is not a lot of time especially when you compare it to the Inspiration 4 mission's approximately 96 hour duration that's not even using half of Crew Dragon's endurance...
Boeing plans to rotate between two reusable crew modules for all planned Starliner missions. Each flight will use a new service module, which provides propulsion and power generation capacity for the spacecraft.
That’s always been the plan. Not sure what it says about the value of the contract that it only funds two capsules. Not sure who foots the bill if they have to retire (or god forbid) lose one of them.

The result was that Boeing took a $400M hit to their 2020 financial results to pay for the reflight.Firm Fixed Price puts the financial risk where it belongs for CCP: with the contractors.Cost Plus is appropriate only when there is undue financial risk to the contractors due to, for example, the need to develop all-new technology.But the latter was not the case with CCP. Flying people up and down to LEO is an art mastered by the US aerospace industry over half a century ago. No "all-new" technology involved. And thus no need for Cost Plus.

Starliner at 90 million per seat compared to Dragon at 55 million and the Starliner problems to date why would anyone choose Starliner? Starliner looks like a dead end with no application outside of commercial crew.

Eventually they'll be Starship, but that's like a person reserving a seat in a limousine just to go to the other side of town.The Commercial Crew ships will have NASA/FAA standards of safety, launch vehicles run by experienced providers, with no requirements for NASA contracts to fly, just cash.The spacecraft, along with Dream Chaser Cargo and more, open up the secondary commercial applications in Earth orbit that were moribund without any way of getting there affordably or at all, period. Axiom Space, to take one example, can not exist without CC availability.Commercial Crew are "space Ubers." And you want alternatives in case the other one is busy or too expensive.What ULA can do to lower the cost of Starliner flights to be competitive is another debate. But at least the option of a human spacecraft exists at all.
Not necessary. There is always the awful option (for Boeing) of riding up on the Falcon 9. It will a lot less complicated than that aerodynamic ring structure around the Centaur.

On the contrary it is possible that a skirt would be needed with the smaller-diameter Falcon 9. <snip>.
The Falcon 9 usually fly with the 5.2 meter payload fairing, which is much wider than the Starliner.

There are no rockets available to launch starliner. All atlas v are spoken for, and ula has NO plans currently to human rate Vulcan. It's just not possible for starliner to be commercial (even aside from it costing 2x as much as dragon).

It will however need a new payload adapter as Starliner diameter is less than Centaur V diameter (4.65 vs 5.4 meters)
Needing a new adapter goes without saying. It would need a new one for any new rocket regardless of the diameter. ...
It's basically impossible for starliner to do a commercial launch. They have a set number of atlas v rockets and nothing else. Vulcan isn't human rated.

I'm not usually a fan of brief negative responses but all the claims that "Vulcan is not human rated" are getting old.Yes: Vulcan is not currently human rated but that can change. Atlas V also lacked human rating at the start.This is a smaller challenge compared to signing up actual customers, or even getting crew to the ISS.
Interesting thread from Scott Manley:https://twitter.com/DJSnM/status/1439816198703628292--- Tony
Especially once Axiom modules are available, couldn't this privately funded astronaut stay the entire ~6 month crew rotation duration? I don't think NASA allows this at present, but they could permit it in the future.
The critical item here is docking ports ... not sure they have quite enough (could a Prichal port be used???). If not would have to delay until the Axiom stuff is in orbit but that might align with Vulcan crew rating anyway ...
Something like this could work, but I'm expecting something more like:- very short term, they sell the extra seats to Nasa - once properly flying, they will do 2 crew rotation flights a year like SpaceX... Snip
Quote from: jebbo on 09/20/2021 07:17 pmThe critical item here is docking ports ... not sure they have quite enough (could a Prichal port be used???). If not would have to delay until the Axiom stuff is in orbit but that might align with Vulcan crew rating anyway ...There are only two IDS ports right now, so it is not possible to do a direct handover while a Dragon is docked, as that would require three ports: two for the Starliners and one for the Dragon. Prichal has SSVP ports, as is typical for the Russian segment. I believe Axiom plans to launch one IDS docking adapter with each Hub module.
I'm curious.One area that seems to be missing from this discussion is selling Starliners to third party operators.After-all, Boeing is in the business of selling their commercial products (airplanes) to operators (airlines and leasing companies).Might it make financial sense for a company like Axiom to purchase one (or more) CST-100s and then independently contract for launch services? Find their own economies of operation?Yes, currently they are limited to the AtlasV as a launch vehicle, but they would have the incentive to explore or even fund alternative LVs for their service. (Note, in a commercial scenario, LV redundancy is not a requirement.)
So if they don't need an extra Astro, I'd expect cargo to fly instead. Remember that 5th seat goes both uphill and downhill, so it takes place of NASA downmass too.
As to the second point, NASA standard rotation is 6 months. Even when both providers are operational, there will only be 2 NASA crew rotation flights total per year. They aren't suddenly going to switch to 4 rotation flights per year...
( Oh, and none of the Russian ports are compatible with American crew vehicles )

Even though NASA had Lockheed (then USA) "operate" the shuttle, Rockwell (Boeing) still did a lot of work and was paid a lot of money.
This doesn't affect the overall accuracy of your statement, but USA was not just Lockheed, but a 50:50 joint venture of Rockwell and Lockheed (later 50:50 Boeing:Lockheed after the Boeing acquisition of Rockwell). Rockwell's half of USA was the former RSOC/Houston, which was distinct from RI/Downey that had the shuttle sustaining contract.
The fact the shuttle failed to be a commercial success using the operating company model means that others can see what worked and what didn't.

That has nothing to do with my point. The shuttle failed commercially long before the operating company model was employed. The point is that space launch is too complex for the OEM not to be involved in daily operations.
I disagree. Ballistic missiles and satelite launch vehicles are of comparable complexity, and the former are not operated by their respective OEM on a daily basis.

They can take lower reliability (70%) and most are solid propellant. Anyways, the OEMs built them up and placed them in the silos and designed the trajectories.

No more comparable than RC airplane is to an airliner. ICBMs are less complex than satellite launch vehicles. ICBM "operators" just turn keys. Not really "operators". If they turn the key, the OEM has to come back and reload the silo.ICBM's used for space launch are handled much differently.Being able to just turn a key for launch is a far more difficult problem to solve than required for something that needs an engineering staff to launch. A vehicle that can stand by for years safely with a nuclear warhead attached to it is a huge engineering challenge compared to something that needs to survive ready to launch for a few days. A vehicle that can be serviced by military personal is a far greater challenge than a vehicle serviced by engineering staff. A system engineered to carry the destructive power to destroy a city cannot have an accident on the pad.
I really don't think human-rating Vulcan is an issue. The rocket was designed with that in mind so it's likely primarily a question of paperwork and the necessary flight record.The real question with Vulcan is the timeline. With the first launch not scheduled before 2022, and the next two being Dream Chaser, that puts a first potential Vulcan flight for Starliner into 2023 at the absolute earliest even with no further Starliner delays and Boeing having the resources to do the modifications in parallel with the existing program.

Human rating Vulcan is not a (unsolvable) technical issue.It's a financial issue.ULA is waiting for a customer to pay for it.It represents a substantial "barrier to entry" for commercial (non-NASA, non-ISS) Starliner flights.(Anyone have a basis with which to estimate to how much it would cost?) Who is going to pay for it before the first flight?It really looks like an insurmountable barrier for Starliner.Unless Sierra Space needs it for a crew capable Dream Chaser.In which case Starliner would have two competitors.

They already have the Atlas-V launchers needed for this, but there are no other Atlas-V rides available. Boeing has made no statements that I'm aware of that indicate that they're even considering launches of Starliner outside of this Commercial Crew contract.Starliner appears to be already an expensive vehicle relative to Crew Dragon, and adding in the cost of Vulcan crew qualification would only make this worse.
Wouldn't ULA get money from NASA for human rating Vulcan or is it Boeing's investment?

NASA is considering acquisition of Commercial Crew Space Transportation Services from one or more U.S. providers through commercial services contracts. Depending on mission requirements, NASA may purchase single seats, multiple seats within one mission, or seats for an entire mission.
they can withstand intense vibrations from a nuclear attack and launch within a few minutes afterward. Even the ground support equipment has to be extremely robust and yet useable my military personnel.
