1966: Atlas-Agena & Titan-Gemini ~ 1h 40m apart (4x)
This was the shortest time between orbital launches at Cape Canaveral since 1966. //
It seems like SpaceX did everything this year but launch 100 times.
On Thursday night, the launch company sent two more rockets into orbit from Florida. One was a Falcon Heavy, the world's most powerful rocket in commercial service, carrying the US military's X-37B spaceplane from a launch pad at NASA's Kennedy Space Center at 8:07 pm EST (01:07 UTC). Less than three hours later, at 11:01 pm EST (04:01 UTC), SpaceX's workhorse Falcon 9 launcher took off a few miles to the south with a payload of 23 Starlink Internet satellites.
The Falcon Heavy's two side boosters and the Falcon 9's first stage landed back on Earth for reuse. //
These were SpaceX's final launches of 2023. SpaceX ends the year with 98 flights, including 91 Falcon 9s, five Falcon Heavy rockets, and two test launches of the giant new Super Heavy-Starship rocket. These flights were spread across four launch pads in Florida, California, and Texas. //
It's important to step back and put these numbers in context. No other family of orbit-class rockets has ever flown more than 63 times in a year. SpaceX's Falcon rockets have now exceeded this number by roughly 50 percent. SpaceX's competitors in the United States, such as United Launch Alliance and Rocket Lab, managed far fewer flights in 2023. ULA had three missions, and Rocket Lab launched its small Electron booster 10 times.
Nearly two-thirds of SpaceX's missions this year were dedicated to delivering satellites to orbit for SpaceX's Starlink broadband network, a constellation that now numbers more than 5,000 spacecraft. //
As if these statistics weren't enough, SpaceX closed out the year by, yes, setting yet another record. The back to back launches Thursday night took off 2 hours and 54 minutes apart, the shortest turnaround between two SpaceX flights in the company's history. It also set a modern era record at Cape Canaveral, Florida, with the shortest span between two orbital-class launches there since 1966. The Florida spaceport was the departure point for 72 orbital-class rockets in 2023, also an unprecedented level of launch activity there.
SpaceX looks poised to set more records next year. In 2024, SpaceX aims for an average of a dozen launches per month, for a total of 144 rocket flights. The company will get out of the starting blocks early in the new year, with two Falcon 9 launches slated for January 2 and 3.

Seriously. It seems like contemporary space (more specifically spacex) fans talk about reusing rockets as if this is like reusing towels or something.
For the reasons you mention and more, reuse has got very limited use at best. And until we see a series of audited financials that dig deep down into specific areas of their business, we can't even confirm the supposedly game-changing economics of it all. Spacelaunch is about as niche of a task as there could be. It's not analogous to reusing towels or toothbrushes or cars or even airplanes. ...

From the layperson all the way to NASA, which itself so clearly seemed to doubt their choice even within their own initial selection statement for HLS. Even u/MrPennywhistle in his ever optimistic and infectious enthusiasm helped inadvertently spread a really bizarre belief that has since taken on a new life in popular space discourse: mainly, the strange understanding that there's somehow more to be learned by rapidly, carelessly, prematurely and DELIBERATELY destroying hugely expensive and underdeveloped test-articles. I think it was following AMOS-6 and what he meant to communicate was that having a failure prior to your main mission is a saving grace to be taken advantage of: that there's much to be learned when things go kaboom by accident. Instead it's become a thing where people literally cheer their lungs out when they see a fractional prototype of a giant and expensive craft (that Artemis is desperately banking on) fail catastrophically and tear itself into a million pieces right before their eyes because "tHeReS sO mUcH DaTa! ... //

The hit to payload because of reuse isn't much of an issue because you can design the rocket to be as big as you need in order to get the payload into its desired orbit. Sure, it results in a larger, more complex rocket for the same mass of payload, however you won't have to throw the entire thing away after one mission, which will result in lower costs.
SpaceX has hit their aspirational goal of 10 reuses per booster with Falcon 9 and they are continuing beyond it. Their most used boosters have been used 17 or 18 times. They have reused 39 boosters to date, for a total combined 251 landings. Right now they have a successful landing streak of more than 116 since 2021.
This year they have launched only 4 new boosters, the other 81 launches used previously-flown boosters. Similar story for last year when they only launched 4 new boosters, while launching 56 times with reused boosters. For comparison, ULA has so far launched only 3 times this year, and 8 times last year.
SpaceX is operating on an entirely different level than the rest of the launch providers. [They are launching more mass per quarter than the rest of the world combined][2]. Is it a coincidence that they just so happen to be the only launch provider doing reuse at the moment?
As for destructive testing, it is their preferred method because it allows for changes to be made more easily and they can find unknown flaws quicker. They could spend years developing and reviewing the design of Starship so that it would likely work perfectly on the 1st time like SLS. Or they could test the design they have, see what goes wrong with it, and then make improvements to the problem areas for next time. Also these prototypes are way cheaper than an operational rocket like SLS which costs like $2.1 billion alone to launch. I mean, SpaceX is only going to get about $3 billion total from NASA for the first lunar lander and its development. That money is spread out across all the various development milestones. The fixed-price contract incentivizes SpaceX to work efficiently with both their time and money.
And the reason the SpaceX employees and fans cheer during test launches is because the prototypes are: 1- very cool to see (it's like Kerbal Space Program in real life) and 2- they show visible signs of progress. IFT1 tested the launch infrastructure, the quick disconnects were successful and the rocket made it past the tower, SuperHeavy had never flown before that. IFT2 demonstrated even more progress with the deluge system protecting the pad, all engines running nominally through to the hotstage separation, and Starship almost making it to its intended trajectory.

Amazon announced Friday that it has purchased three Falcon 9 rocket launches from SpaceX beginning in mid-2025 to help deploy the retail giant's network of Kuiper Internet satellites. //
Last year, Amazon bought up most of the Western world's excess launch capacity from everyone but SpaceX, securing 68 rocket flights from United Launch Alliance, Arianespace, and Blue Origin to deploy thousands of satellites for the Kuiper broadband network. Amazon previously contracted with ULA for nine Atlas V launches to support the initial series of Kuiper launches, the first of which lifted off in October with Amazon's first two Kuiper prototype satellites. More Atlas Vs will start launching operational Kuiper satellites next year. //
Amazon is helping to fund a big expansion in ULA's footprint at its Florida launch base, an effort that will double the ULA's launch capacity. The investment to fund the growth in ULA's capability to support Kuiper launches totals about $2 billion, with around $500 million going toward upgrades at Cape Canaveral.
Those upgrades include the outfitting of a second vertical hangar and a second mobile launch platform for Vulcan rockets, alongside the integration facility and launch table already built to support the first few Vulcan missions. Having dual lanes for launch processing in Florida will allow ULA to fly as many as 25 Vulcan rockets per year, the company says.
ULA and its subcontractors are also expanding factory space at locations around the country to produce more Vulcan engines, solid rocket boosters, and payload fairings for the Kuiper missions.
Amazon and ULA officials hope these investments will spare the Vulcan rocket from the growing pains experienced by other launch vehicles as they enter service. For example, it took 31 months for the Atlas V rocket to reach its fifth flight in the early 2000s. A decade ago, SpaceX's Falcon 9 made its fifth flight 33 months after its inaugural launch.
That won't do if Amazon is going to deploy more than 1,600 Kuiper satellites by mid-2026.
During Artemis I, NASA’s new mega Moon rocket, the Space Launch System (SLS), roared into the night sky and sent the Orion spacecraft on a 1.4-million-mile journey beyond the Moon and back. //
The spacecraft reached a maximum distance from Earth when it was 268,563 miles away from our home planet. Orion surpassed the record for distance traveled by a spacecraft designed to carry humans, previously set during Apollo 13.

Starship Flight Test 2
November 18, 2023, at 7:02 a.m. — SpaceX's Starship launches on its second fully-integrated flight test from the orbital launch pad at Starbase in Texas. The rocket successfully reached stage separation under the power of 33 Raptor engines on the Super Heavy booster, with the new hot-staging separation method a success! Starship made it to space and was later terminated, while the Super Heavy booster experienced a rapid unscheduled disassembly shortly after stage separation.
Starship returned to integrated flight testing with its second launch from Starbase in Texas. While it didn’t happen in a lab or on a test stand, it was absolutely a test. What we did today will provide invaluable data to continue rapidly developing Starship.
Starship successfully lifted off under the power of all 33 Raptor engines on the Super Heavy Booster and made it through a successful stage separation. The booster experienced a rapid unscheduled disassembly after its boostback burn following the successful stage separation while Starship's 6 second stage Raptor engines fired for several minutes as the Ship climbed to an altitude of ~150 kilometers.
With a test like this, success comes from what we learn, and today’s test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary.

CAPE CANAVERAL, Florida—In three-and-a-half years of service, one of SpaceX's reusable Falcon 9 boosters stands apart from the rest of the company's rocket inventory. This booster, designated with the serial number B1058, has now flown 18 times. For its maiden launch on May 30, 2020, the rocket propelled NASA astronauts Doug Hurley and Bob Behnken into the history books on SpaceX's first mission to send people into orbit.
This ended a nine-year gap in America's capability to launch astronauts into low-Earth orbit and was the first time a commercial spacecraft achieved this feat. At that time, the rocket was fresh from SpaceX's factory in Southern California, glistening white in color, with a bright red NASA "worm" logo emblazoned on the side.
Over the course of its flights to space and back, that white paint has darkened to a charcoal color. Soot from the rocket's exhaust has accumulated, bit by bit, on the 15-story-tall cylinder-shaped booster. The red NASA worm logo is now barely visible. //
With Friday night's flight, this particular booster has launched 846 satellites, most of which have been Starlinks. When you let it sink in, that's a remarkable number. It's more than the total number of satellites in OneWeb's broadband network. The launch Friday night, numbered Starlink 6-26, brought the total number of functional Starlink satellites in orbit to more than 5,000, according to a tabulation by Jonathan McDowell, an astrophysicist and expert tracker of spaceflight activity. //
SpaceX officials often emphasize that, even after 277 launches of Falcon 9 or Falcon Heavy rockets, engineers learn something with each flight. It certainly helps when you get the majority of the rocket (the booster and the payload fairing) back after each launch, allowing technicians to perform inspections and refurbishment, occasional engine swaps, upgrades, or anything that needs to be done between missions.
