Capstone: The New Space Era & Commercial Spaceflight

History of Space Exploration

Chapter 10 · Capstone: The New Space Era & Commercial Spaceflight

The course began with three theorists and ends with private companies flying astronauts. This capstone covers the commercial era, SpaceX above all, and then looks back over the ten chapters. The sources are three reference articles, on SpaceX, on reusable launch vehicles and on NASA's Commercial Crew Program. They give dates well and cost savings poorly, and the chapter says so.

SpaceX

SpaceX was established on 14 March 2002 in El Segundo, California, by Elon Musk. Its first successful orbital launch came on 28 September 2008, after three prior failures that the source says nearly bankrupted the company.

DateEvent
2006A $396 million COTS award from NASA.
December 2008A $1.6 billion Commercial Resupply Services contract.
May 2012Dragon becomes "the first commercial spacecraft to deliver cargo to the International Space Station."
December 2015First successful recovery of an orbital-class first stage, Falcon 9 Flight 20 (the reusable launch article gives 21 December 2015).
March 2017SES-10 is "the first time a re-launch of a payload-carrying orbital rocket went back to space."
May 2020Crew Dragon launches two NASA astronauts, "the first private company to send astronauts to the International Space Station."
Company Sources and Wording Most of these lines are quotations from the SpaceX article. "The first" in each case is the article's own claim, and I did not check them against other sources. The NASA awards are the article's figures, and it does not say what they paid for beyond the labels COTS and Commercial Resupply Services.

Starship

The source says multiple Starship test flights took place between 2023 and 2026, with the twelfth flight in May 2026 being "the first flight test to carry a payload into orbit." It notes that industry observers "referred to the test flight as a success" regarding Starship's first orbital attempt despite a mid-air explosion, which suggests interpretive disagreement. I do not know which flight the explosion refers to, and the source does not say, so I do not describe it.

Reusability

Reusable launch vehicles have recoverable components that can be reflown, reducing the need to manufacture new parts for each mission. The most commonly reused elements are rocket stages, and fairings and engines can also be recovered.

Earlier Attempts

The Space Shuttle (1981 to 2011) was the first operational reusable system, though only partly: it recovered the orbiter and solid rocket boosters and expended the external tank. The orbiter flew 135 times, the source says, matching Chapter 7's flight count. The 1990s DC-X was an experimental vertical takeoff and landing prototype.

SpaceX

The first successful vertical landing of an orbital-class booster was on 21 December 2015. The source says the company has since been "routinely recovering and reusing their first stages, as well as fairings," and that Falcon 9 booster B1067 reached a record 37 flights as of September 2026.

Blue Origin

New Shepard, suborbital, demonstrated reusability from 2015. New Glenn achieved its first booster recovery in November 2025, making Blue Origin the second company after SpaceX to recover an orbital-class booster.

Savings Asserted, Not Shown The article says reusability reduces launch costs significantly by eliminating per-flight manufacturing. It also says the benefits "can be diminished by the cost of recovery and refurbishment," that reusable stages carry extra weight for landing gear, heat shields and spare propellant, that refurbishment can be "lengthy and expensive," and that stages eventually need retiring. It gives limited quantitative evidence, and the SpaceX article gives no per-launch cost. So the chapter cannot say how much reuse saves. Chapter 7 made the same point about the Shuttle: a reusable design stayed expensive.

Commercial Crew

The Commercial Crew Program provides "commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA." In 2014 NASA awarded SpaceX $2.6 billion and Boeing $4.2 billion to develop crewed spacecraft for station rotations.

  • Demo-2: launched in May 2020 with Bob Behnken and Doug Hurley, the final crewed test flight before operational missions.
  • First operational flight: SpaceX Crew-1 launched on 16 November 2020 with four astronauts.
  • Boeing Starliner: its first crewed test flight in June 2024 experienced helium leaks, reaction control failures and an isolation valve malfunction. NASA returned the spacecraft uncrewed, with its crew joining SpaceX Crew-9. It did not receive system certification, and in February 2026 NASA classified the failures as a "Type A mishap," the most serious category.
The End of a Dependence Between the Shuttle's retirement in 2011 and Crew-1 in 2020, NASA relied on the Russian Soyuz. The source says the programme's operational success eliminated that dependency, though Soyuz seats were bought as contingency during delays. That closes the thread from Chapter 7. It is also a contrast with Chapters 3 to 6, where the two powers competed. The Crew Dragon flights served a station (Chapter 8) that the source describes as run by five agencies including Russia's.
Two Contract Sizes, Not a Comparison SpaceX received $2.6 billion and Boeing $4.2 billion. The source does not say what each contract covered or why the amounts differ, and one company's vehicle has flown operationally while the other's has not been certified. I do not draw a conclusion about value for money.

Looking Back

ChapterSubjectThe caution the chapter kept
1The three theoristsIndependence between them was not established.
2V-2 and PaperclipDeath figures conflict, and responsibility is disputed.
3SputnikWhether the "crisis" was real or manufactured.
4Gagarin and ShepardThe landing was concealed for years.
5ApolloConflicting cost and astronaut-count figures.
6Apollo 11 and 13Two fuel figures, one disputed word.
7The ShuttleBoth accidents had organisational causes.
8Space stationsNo ISS cost in the sources.
9RobotsTwo durations for one rover, and a misquotation.
10The new eraSavings from reuse are not quantified.
What Repeats Two patterns recur across the ten chapters, and both are my reading of the sources and not claims any of them makes. First, in several accidents and programmes the sources describe schedule or cost pressure alongside a known technical risk (Chapters 5 and 7, and Starliner here). Second, in several chapters a memorable story turned out to be a paraphrase or a later label (the "retroactive" first object in space in Chapter 2, "My battery is low" in Chapter 9). Whether either is a genuine pattern, and not a coincidence of which topics I chose, is not something the sources can settle.
What This Course Did Not Cover It rested on one to three short reference articles per chapter. It does not cover China's, India's, Europe's or Japan's space programmes, satellites and their applications, the science that space missions returned, the military uses of space, or the accounts of the people who worked on the programmes. Chapter 7's and Chapter 8's boxes list further gaps. The course is an outline built from reference summaries, and a fuller history would start from the reports and primary sources that those articles cite.

Hands-On Exercises

Exercise 1

A student writes "Reusable rockets have made spaceflight cheap." Use the chapter and Chapter 7 to answer it.

Exercise 2

List the "first" claims the chapter attributes to SpaceX and say how you would check each one.

Exercise 3

Pick one of the two recurring patterns named in "What Repeats" and say what evidence beyond this course a historian would need to call it a real pattern.
