SpaceX’s Falcon 9 Block 5 set for first Cargo Dragon spacecraft launch
After a slight 24-hour delay at NASA’s request, SpaceX is ready to support Falcon 9 Block 5’s first launch of Cargo Dragon and the company’s 16th operational mission to resupply the International Space Station (ISS).
Carrying just under 2600 kg (5700 lbs) of science experiments, ISS hardware, and replenishable goods, CRS-16 will be the fifth time SpaceX has reused a Cargo Dragon capsule that has already been to orbit, with this particular capsule having launched in February and reentered in March of 2017.
To allow for time to replace parts of an @ISS_Research experiment, the launch of the @SpaceX cargo resupply mission to the International @Space_Station is now targeted for 1:16pm ET on Wed., Dec. 5. Details: https://t.co/EvShjud5ws pic.twitter.com/4Ug8xmfs69

Aside from being the first NASA-certified launch of SpaceX’s recent Block 5 upgrade to the Falcon rocket family, CRS-16 will become the first attempted East Coast land-landing of a Falcon 9 Block 5 booster, hopefully seeing B1050 safely recovered at one of the company’s two Landing Zones (LZ-1 or LZ-2) on the Florida coast. Above all else, this type of landing – known as a Return To Launch Site (RTLS) recovery – indicates that Falcon 9 is able to fly a fairly gentle launch and reentry trajectory, owing to a combination of a light payload and low-energy target orbit. As such, B1050 could be a prime candidate to break SpaceX’s launch turnaround record of 72 days – the new Block 5 booster will be subjected to one of the upgraded rocket’s gentlest landings yet.
2018 has been a landmark year for SpaceX’s program of Falcon 9 reusability, evidenced by the fact that a full 60% of the company’s 19 (20 if CRS-16 is a success) launches have flown on or with flight proven boosters. That impressive ratio is likely to only grow further as we head into 2019, to the extent that – by 2020 – the launch of a new Falcon 9 or Falcon Heavy booster could be downright rare.
On the Dragon side of things, SpaceX completed the last launch of a wholly new Cargo Dragon in August 2017, nearly 16 months ago. Since then, all Cargo Dragon launches have featured refurbished capsules, although the spacecraft’s trunk section – featuring some propellant, solar arrays, and storage space – is expended after each mission and must thus be replaced. As of now, SpaceX has only one or two flightworthy Cargo Dragons left that have completed fewer than two trips to orbit and back, meaning that a minimum of two of the company’s remaining CRS-1 missions (CRS-17 through 20) will have to be their given capsule’s third orbital launch. Thankfully, Cargo Dragon has long been designed for three launches per capsule lifetime.
The first of those third orbital reflights will almost certainly kick off sometime next year. In the meantime, SpaceX’s CRS-16 launch will be livestreamed as usual and can be viewed here, beginning later today around 10am PST (1pm EST, 18:00 UTC).

NASA has filed a procurement notice announcing its intent to add six post-certification missions to SpaceX’s existing Commercial Crew Transportation Capability contract. The agency said it would order up to three of those missions immediately upon adding them to the contract, with the remaining three available as needed through the end of the International Space Station’s planned operations in 2030.
The reason for the expansion is straightforward. NASA cited recently shortened ISS mission durations, technical issues and schedule delays encountered by Boeing, the allocation of missions between Boeing and SpaceX, and the ongoing technical challenges of maintaining a reliable crew transportation capability as the driving factors behind the decision. Boeing’s CST-100 Starliner has still not been certified for crewed flights, and a cargo-only Starliner mission was not included on NASA’s most recent mission manifest. With Boeing effectively sidelined for the foreseeable future, SpaceX is the only American company capable of rotating crews to the station.
The history behind this contract tells the fuller story of how SpaceX got here. NASA originally awarded SpaceX its Commercial Crew contract in 2014 for $2.6 billion. In 2022 NASA modified the contract to add five missions covering Crew-10 through Crew-14, worth $1.436 billion, bringing the total contract value at that point to $4.9 billion. The recent May 18 filing by NASA extends that runway further, with Crew-12 currently docked at the station and Crew-13 assigned and targeting a mid-September 2026 launch.
According to a report by SpaceNews, NASA stated in its filing: “It is necessary to award additional PCMs to SpaceX given the recently shortened ISS mission durations, technical issues and schedule delays encountered by Boeing, the allocation of missions between Boeing and SpaceX, NASA’s projections for when an alternative crew transportation system may become available, and the ongoing technical challenges of maintaining a reliable capability for crewed flights to ISS.”
No dollar value for the new six missions has been publicly confirmed yet, but based on the 2022 precedent of roughly $287 million per mission, the new block could represent close to $1.7 billion in additional contract value. With SpaceX simultaneously preparing Starship as NASA’s Artemis lunar lander, filing its S-1 for a June IPO, and now absorbing more ISS crew rotation work, the company’s role as the primary contractor for American human spaceflight is no longer a matter of circumstance. It is NASA policy.

Elon Musk called it Epic: The full story of SpaceX’s Starship Flight 12
Starship V3 reached space, survived reentry, and proved it can fly with engines out.
After two scrubbed attempts, SpaceX launched Starship V3 on Friday, May 22 from the brand new Pad 2 at Starbase, Texas, completing the most technically complex test flight the program has attempted and moving the bar in ways that matter for everything from commercial satellites to the first human Moon landing since 1972.
The Super Heavy booster lost an engine early during ascent and several more failed during its boostback burn, sending the stage into an off-nominal descent that ended in a hard landing in the Gulf of Mexico. SpaceX had planned a soft splashdown rather than a tower catch on this first V3 flight, so losing the booster was expected to be acceptable within the test parameters.
Ship 39 told a different story. The Starship upper stage reached its planned sub-orbital trajectory despite losing one of its vacuum Raptor engines, with the remaining engines compensating for the loss and keeping the vehicle on course. The spacecraft then survived atmospheric reentry, completed its belly-flip maneuver, and made a controlled upright splashdown in the Indian Ocean west of Australia.

The payload test is where Flight 12 separated itself from every previous Starship mission. SpaceX deployed 22 objects including 20 Starlink simulator satellites sized like next-generation V3 Starlink units, plus two specially modified satellites equipped with cameras that scanned Starship’s heat shield from orbit and transmitted imagery back to operators.
The broader significance of what was tested on Friday goes well beyond one mission. Every future Starship deployment, whether it is a batch of operational Starlink V3 satellites, cargo bound for the Moon, or eventually crew headed to Mars, depends on SpaceX being able to inspect and certify the heat shield quickly between flights. The camera-equipped satellites deployed on Flight 12 are the first step toward making that inspection process automated and data-driven rather than manual and time-consuming. If SpaceX can scan the heat shield from orbit after every reentry and flag damaged or missing tiles before the vehicle even lands, it fundamentally changes the turnaround time between flights. For a program that needs to refuel Starship in orbit using ten or more tanker launches before a single Moon mission can depart, launch cadence is everything. Friday’s payload test can be seen as building the maintenance infrastructure for rapid reusability.
Elon Musk took to X, following the successful tests, and noting: “Congratulations @SpaceX team on an epic first Starship V3 launch and landing!” “You scored a goal for humanity.”
The stakes behind that goal are concrete. NASA has selected Starship as the Human Landing System for Artemis IV, targeting a crewed Moon landing in 2028, and SpaceX has yet to demonstrate a full orbital flight, in-orbit refueling, or docking with an Orion capsule. Flight 12 proved V3 can fly, survive reentry, and deploy payloads under engine-out conditions. That is the foundation everything else has to be built on, and with a SpaceX IPO targeting June 2026, the timing of that proof of concept could not have been more useful.
SpaceX has decided to stand down from what was supposed to be the first test launch of Starship’s v3 rocket tonight after a minor issue with a hydraulic pin delayed the flight once more.
The company scrubbed its first test flight of the upgraded Starship v3 on May 21 in the final minutes of the countdown. SpaceX CEO Elon Musk quickly took to social media platform X, explaining that a hydraulic pin on the launch tower’s “chopsticks” arm failed to retract properly.
Musk added that the company would fix the issue this evening. SpaceX will attempt another launch tomorrow night at 5:30 p.m. CT, 6:30 p.m. ET, and 3:30 p.m. PT.
The hydraulic pin holding the tower arm in place did not retract.
If that can be fixed tonight, there will be another launch attempt tomorrow at 5:30 CT. https://t.co/DJAdvDYQpH

The countdown for Starship Flight 12 — featuring the taller and more capable V3 stack with Booster 19 and Ship 39 — had been progressing smoothly until the late-stage issue surfaced. The Mechazilla tower arm, designed to secure the vehicle on the pad and eventually catch returning boosters, could not complete its retraction sequence.
SpaceX teams immediately began troubleshooting the hydraulic system for an overnight repair.
Starship V3 introduces several significant upgrades over earlier versions. These include greater propellant capacity, more powerful Raptor 3 engines, larger grid fins, enhanced heat shielding, and an improved fuel transfer system.
We covered the changes that were announced just days ago by SpaceX:
SpaceX unveils sweeping Starship V3 upgrades ahead of May 19 launch
The changes are intended to increase payload performance, support higher flight rates, and advance the vehicle toward operational missions, including Starlink deployments, NASA Artemis lunar landings, and future crewed Mars flights. The debut flight from Starbase’s new Launch Pad 2 marked an important milestone in scaling up the fully reusable Starship system.
This stand-down highlights the intricate challenges of preparing the world’s most powerful rocket for flight. Despite extensive pre-launch checks, a single component in the ground support equipment can force a scrub.
The incident aligns with Starship’s proven iterative development approach. Previous test flights have encountered both successes and setbacks, each providing critical data that refines hardware and procedures. Some outlets may call some of these flights “failures,” when in reality, they are all opportunities for SpaceX to learn for the next attempt.
With V3, SpaceX aims to reduce ground-system dependencies and increase launch cadence to meet ambitious long-term goals.
