If reusable configuration launches 70% of payload, why use 50% in your calculation?  Refurbishment cost also way overstated.  Begin with the end in mind?

Put the Elon-hating aside, and it’s easy to see SpaceX’s success is forcing the entire industry to follow their lead:

If reusable rockets are not worth the trouble and have no significant benefits, then why are Russia, ESA, China, ULA, Blue Origin, Rocket Lab…, and many more, ALL spending millions developing new rockets to switch over to that model as quickly as they can?

Edit:  Using expendable rockets to go to space is like throwing each airplane away after only one flight.  Reusability is key.

Crews pour concrete at the Landing Pad in preparation for Starship SN10's maiden flight. SpaceX is making the pad wider & thicker. SN10's flight could occur early as this coming week as crews test its aft flaps.

<With rapid curing additives you can load concrete in a few hours.
This is commonly done with freeway repair etc.
Won't reach the maximum strength as slow cure would, but this isn't a bridge beam or anything, just a slab on grade, so you just make it a little thicker to compensate

MEMPHIS, Tenn.--(BUSINESS WIRE)--Inspiration4, the world’s first all-civilian mission to space, has announced its second crew member, Hayley Arceneaux of Memphis, TN, a 29-year-old physician assistant at St. Jude Children’s Research Hospital® who was treated as a child for bone cancer at St. Jude. Arceneaux joins Inspiration4 mission commander Jared Isaacman. She will occupy the mission seat representing Hope.

The mission name Inspiration4 recognizes the four-person crew’s purpose – to send a humanitarian message of possibility and inspire support for St. Jude – and represents the pillars of Leadership, Hope, Generosity and Prosperity.

The remaining two seats representing Generosity and Prosperity are available to the general public through February 28, with details available at the mission website, Inspiration4.com. The Generosity crew seat can be secured by a member of the public who enters for an opportunity to join the flight to space. The Prosperity seat is available to any deserving entrepreneur who utilizes the new Shift4Shop eCommerce platform to submit their idea and be selected by a panel of distinguished judges.

FAA clears SpaceX Starship prototype for third launch and landing attempt
By Eric Ralph February 22, 2021
Quote
The US Federal Aviation Administration (FAA) has already cleared Starship serial number 10 (SN10) for flight, cutting short any potential licensing drama facing SpaceX’s latest high-altitude Starship launch efforts.

Less than three weeks ago, Starship serial number 9 (SN9) lifted off from SpaceX’s South Texas launch facilities after a tedious week or so of opaque licensing ‘issues’ only vaguely touched upon by the FAA. The regulatory body never actually offered an explanation for why it publicly dragged SpaceX through the coals in January and February for purported “launch license violations” during Starship SN8’s December 8th launch debut, nor why the FAA only brought up those claimed issues more than a month after the fact.

SpaceX has already filed temporary flight restrictions (TFRs) with the FAA for possible SN10 launch attempts on Tuesday, Wednesday, or Thursday, suggesting that the company hopes to turn Starship around for flight as few as 24-72 hours after a successful static fire. Stay tuned for updates as SpaceX works to conduct its third Starship launch before the month is out.
https://www.teslarati.com/spacex-starship-third-launch-landing-faa-clearance/

Temporary Flight Restrictions have been posted for Starship SN10's test flight. Opportunities are Feb. 23 through Feb. 25.

NASA confirms the rumor I posted earlier, that the SLS Green Run test hot fire will be delayed from February 25 due to a malfunctioning valve.

The last time there was a valve issue with the SLS it delayed the Green Run test by about six weeks. I don't know if there will be a similarly long delay this time.

Green Run Update: NASA Investigating Valve Performance Before Second Hot Fire
February 22, 2021
Quote
NASA’s is reviewing the performance of a valve on the core stage of the Space Launch System rocket before proceeding with a second hot fire test at the agency’s Stennis Space Center near Bay St. Louis, Mississippi.

During checkout preparations over the weekend, engineers determined that one of eight valves (a type of valve called a prevalve) was not working properly. This valve is part of the core stage main propulsion system that supplies liquid oxygen to an RS-25 engine. During the first hot fire, all four liquid oxygen valves performed as expected as did the four liquid hydrogen valves. NASA and the core stage lead contractor Boeing will identify a path forward in the days ahead and reschedule the hot fire test that was originally scheduled for Feb. 25. …

Eastern Range discusses drive toward “airport model” operations, eyes increased launch demand
written by Justin DavenportFebruary 23, 2021
Quote
A few years ago, the @45thSpaceWing set a goal of supporting 48 launches per year from Florida. As they aim to meet that this year, the Range now looks to adopt a more "airport-like" model over the next 9 years.

The entire Eastern Range is looking at a projected cadence of 60 launches per year in the near future, with that number increasing to upwards of 96 launches a year by 2030, if not more.

To this end, Mr. Cabana, Brig. Gen. Purdy, and Mr. Monteith discussed the “range of the future,” including a pivotal swing toward a more airport-like model of launch support that would routinely be capable of supporting one to two launches per day. …

A longish think piece on private astronaut flights, the democratization of space and what that means for the future of NASA.

“We at NASA should always be doing the next thing, the thing where the profit motive is not as evident and where the barriers to entry are still too high for the private sector to really make a compelling business case.”  — Phil McAlister, NASA’s director of commercial spaceflight.

“A necessity, it will allow NASA to work as a specialist entity and allow for more innovation and modernisation of future flight hardware as well as an ability to work without diplomatic influences pulling and prying missions to breaking point.” — David Alan Rodgers

As private companies erode government’s hold on space travel, NASA looks to open a new frontier
Christian Davenport
Feb. 25, 2021
Quote
The four astronauts who will fly aboard a SpaceX mission by the end of the year will be a bunch of private citizens with no space experience. One’s a billionaire funding the mission; another a health care provider. The third will be selected at random through a sweepstakes, and the last seat will go to the winner of a competition.

In the new Space Age, you can buy a ticket to orbit — no need to have been a fighter pilot in the military or to compete against thousands of other overachievers for a coveted spot in NASA’s astronaut corps.

In fact, for this mission, the first comprised entirely of private citizens, NASA is little more than a bystander. It does not own or operate the rocket that will blast the astronauts into space or the capsule they will live in for the few days they are scheduled to circle the Earth every 90 minutes. NASA has no say in selecting the astronauts, and it will not train or outfit them — that will all be done by Elon Musk’s SpaceX.

The money to pay for the flight also will not come from NASA — or any other government account. The cost of the project is being born by a billionaire, Jared Isaacman, who has set it up as a fundraiser for St. Jude’s Research Hospital and a promotional device for his business, Shift4Shop, which helps businesses set up websites and process payments.

This is the new look of human space exploration as government’s long-held monopoly on space travel continues to erode, redefining not only who owns the vehicles that carry people to space, but also the very nature of what an astronaut is and who gets to be one.

And it comes as NASA confronts some of the largest changes it has faced since it was founded in 1958 when the United States’ world standing was challenged by the Soviet Union’s surprise launch of the first Sputnik into orbit. Now it is NASA’s unrivaled primacy in human spaceflight that is under challenge.

Thanks to NASA’s investments and guidance, the private space sector has grown tremendously — no entity more than SpaceX, which according to CNBC is now worth $74 billion. The commercial space industry is taking on ever more roles and responsibilities — flying not just cargo and supplies to the International Space Station, but even NASA’s astronauts there. The private sector will launch some of the major components of the space station NASA wants to build in orbit around the moon, and private companies are developing the spacecraft that will fly astronauts to and from the lunar surface.

Space enthusiasts, including NASA, see enormous benefit in the shift — a new era of space exploration that will usher in a more capable and efficient space industry. But the changing dynamic also has left NASA, which for decades has set the pace for the American space project, with an uncertain role, a development NASA’s Safety Aerospace Safety Advisory Panel warns could have consequences for years to come.

The growth of companies like SpaceX has "tremendous upside potential — and are accompanied by equally tremendous challenges for managing the risk of human space exploration,” it said in its annual report, released last month. “NASA leadership in human space exploration is still preeminent, but the agency’s role is evolving with critical implications for how risk and safety will be managed.”

SpaceX is set to reuse a fairing half for the FOURTH time on the upcoming Starlink mission.
They might not catch it every time (or even need too!) but the fairing recovery programme has been a major success.
spacex.com/launches/

< Recovery & re-use is an amazing goal. But is it at the point where it can be considered successful already? Those ships and crew must be $$$.
Gavin Cornwell:
Each fairing costs $3 million dollars to manufacture. Ignoring the cost of refurbishment, ships and crew they saved $9 million by reusing this half four times.

Elon Musk says SpaceX ‘will double’ Starlink satellite internet speeds later this year
   “Speed will double to ~300Mb/s & latency will drop to ~20ms later this year,” Musk said in a tweet on Monday.
   Musk added that Starlink will reach customers around “most” of the Earth by the end of 2021, and is expecting to have complete global coverage “by next year.”

Musk explained in the Joe Rogan webcast that they are still testing the best way to attach the black heat tiles to Starship, and the spacing required to deal with cryo-temperatures (and eventual reentry temps) as the steel expands and contracts.  However, unlike Space Shuttle tiles, most Starship tiles will be identical.

That would explain why the Dragon recovery ships have been reconfigured for fairing recovery.
I wonder if they are planning some upgrades or other work?

—— ”Wow. Blue Origin delays maiden flight of New Glenn [heavy lift rocket] until no earlier than Q4 of 2022.”
Quote
Just A. Tinker:
Let me get this straight, @blueorigin is putting off #NewGlenn's maiden flight because they didn't get a government contract they wanted?  I think we drop them out the 'New Space' category then!  Hey, @JeffBezos, if you REALLY want to settle Cislunar space, get your butt in gear!
Ken Kirtland IV:
Yup. The entire appeal of Blue Origin was that funding and economics were not much of an equation due to Bezos cash. It's pretty clear they just want to be a traditional launch provider / defense contractor.

Dave F:
Anybody know how many NGs they're currently constructing? If this one, eventually, files, but goes kaboom, do they have another to play with?
OK I'm willing to be corrected, but with the limited images & what some have said, they appear to be designing a 'flight ready' rocket. As you say, it's complicated yet they haven't even tested the first stage landing. Even NS's test program is best described as 'patchy'.
Why spend money/time designing everything to the nth degree if it's likely to RUD. There's definitely something to be said for SpaceX's quick iteration of sending 'aerosol cans' 40k ft into the air.

< So more than likely Starship would be first methalox to orbit.
< Musk already said, that same like SN1-10 prototypes, Super heavy prototypes will start with fewer engines as they plan overall. If first Starship with booster will be some scaled down version they can beat Vulcan to orbit. But not with massive 34 Raptors version.

Sotiris:
The entire Starship program according to Musk is going to cost 2-3 Billion. BO spend 1/3 of that on the launch pad alone

    New Glenn’s Progress Towards Maiden Flight
Quote
News Feb 25, 2021
As major progress is being made on the New Glenn launch vehicle and its Cape Canaveral facilities, the schedule has been refined to match the demand of Blue Origin’s commercial customers. The current target for New Glenn’s maiden flight is Q4 2022. The Blue Origin team has been in contact with all of our customers to ensure this baseline meets their launch needs.

This updated maiden flight target follows the recent Space Force decision to not select New Glenn for the National Security Space Launch (NSSL) Phase 2 Launch Services Procurement (LSP).

New Glenn - Wikipedia
https://en.wikipedia.org/wiki/New_Glenn
In February 2019, Blue Origin indicated that no plans to build a reusable second stage are even on the company's roadmap.
By December 2020, Blue Origin indicated that the engine delivery to ULA would slip to summer 2021, and ULA disclosed that the first launch of the New Glenn competitor ULA Vulcan would now be no earlier than 4Q2021.

—- Reusable Upper Stage?
Quote
Washington-based startup raises $9.1 million. Stoke Space Technologies—the Renton, Washington-based company founded by veterans of Jeff Bezos' Blue Origin space venture—has attracted $9.1 million in seed investments for extending rocket reusability to new frontiers, GeekWire reports. The first goal will be to develop a new kind of reusable upper stage, Stoke co-founder and CEO Andy Lapsa told the publication.

High-powered advisers ... "That's the last domino to fall in the industry before reusability is commonplace," Lapsa said. "Even right now, I think space launch is in a production-limited paradigm." Retired Air Force Lt. Gen. Steven Kwast, an adviser to Stoke, goes so far as to say that the team reminds him of the Wright brothers. "Stoke has the right idea about ultra-low-cost access to space, and similar to the first manned flight, will change the world of transportation and national security forever," he said.
—- SLS Green Run update
Quote
SLS launch delayed until 2022. During a recent call with reporters about the SLS core stage Green Run test, NASA's Tom Whitmeyer discussed the schedule for the Artemis I flight. In an ideal world in which nothing went wrong, he said, the mission could launch in October 2021. That was unlikely to happen, he acknowledged. And since then, things have already gone wrong, such as with the prevalve issue....

Never tweet while drunk ... Sources have told Ars that the realistic "no earlier than" date for Artemis I inside NASA is now February 2022, and this presumes a successful Green Run hot fire test in early March. We're getting perilously close to the now somewhat infamous prediction I made in 2017 on Twitter—that the rocket would first launch in 2023.

The update is... they’re still working on the valve problem, and won’t set a new date for the test until troubleshooting is done. [But that new date is likely to be no earlier than the middle of March.]

Fixing the problem with this second balky prevalve will take some time because engineers needed to get “under the hood” access to the vehicle, which was already closed out for the Hot-Fire test when the new problem was discovered. In order to get hands on the prevalve, work access needed to be re-established. …
