SpaceX prepares for last launch until August: Caution over cadence

Published

on

After a second automatic T-10s launch abort Monday night, Elon Musk expressed a welcome prioritization of caution over an attempt to break cadence records. As such, the launch team at LC-39A are standing down an attempt today and instead conducting a full review of the Falcon 9 vehicle and ground systems, pushing the launch to either July 5th or 6th. As Musk transparently phrased it, there is only one chance to get a rocket launch right.

Following a truly unprecedented series of launches for the company, there was understandably a bit of annoyance from fans watching the coverage for a second time, as well as from journalists seeking to cover the launch. I think a tweet from former NASA Space Shuttle Program Manager Wayne Hale summed up the proper response most coherently, however, stating that “it’s tough to remain vigilant and do the right thing, extremely tough after a couple of launch scrubs and [with] range closure looming”. Remaining vigilant is precisely what SpaceX is doing by calling off another attempt on July 4th and choosing to instead carefully examine the systems involved to ensure that there is no real issue with pad or vehicle hardware.

For launch companies, there are an untold number of external and internal pressures urging executives to attempt launches, be those financial, political, or something as simple as employees wanting to get home for a holiday. However, past failures of launch vehicles, particularly the Space Shuttle, have demonstrated that constant vigilance is a necessity when dealing with rocketry. Wayne Hale was flight director for forty Shuttle launches. In fact, he became Program Manager the day of the Columbia disaster, which occurred at the beginning of February in 2003.

In this context, his statement is almost certainly intended as positive – albeit solemn – encouragement for the choice to take a more cautious route before attempting another launch. SpaceX itself has experienced two widely publicized failures of the Falcon 9, with the most recent of those having occurred less than ten months ago. After China suffered a complex failure during the second launch of their Long March 5 heavy lift vehicle last Sunday, Musk offered sympathy for those involved. Any failure in the launch industry often acts as a wake-up call for other companies and agencies involved, and undoubtedly becomes a reminder that one cannot become too comfortable or allow launch processes or vehicle manufacturing to become too routine when the stakes are as high as they can be.

It goes without saying that SpaceX is sharply aware of the need to ensure reliability and safety as they march ever closer to the debut flight of Crew Dragon and its first crewed launches, likely to occur in early 2018. If the stakes for launching the payloads of commercial customers are already high, the price of failures that could lead to loss of life are unspeakable and ought to humble those fans and bystanders who may be losing patience while waiting for a third (admittedly enthralling) launch. Those eager to watch SpaceX’s live coverage must seek to remember that the launches we love to watch occur because paying customers have placed trust in SpaceX to deliver their payloads to orbit, be those payloads massive geostationary communications satellites or astronauts and cargo headed to the ISS. Rightfully so, the customer will always come first, and routine live coverage of rocket launches must always be treated as the luxury it is for the indefinite future.

SpaceX has successfully recovery and reused both Falcon 9 and Cargo Dragon in the last several weeks, and has also recovered three first stages from the three related launches that occurred in that same time period. (SpaceX)

Admittedly, a cornerstone of SpaceX’s mission as a company is making access to orbit reliable, affordable, and routine, but there will always be risk in rocket launches, just as there will always be risk when one boards a plane, drives a car, or simply walks down the sidewalk along a busy street. Minimizing and reducing the risk present in spaceflight will take a considerable amount of time and effort, and doing what is necessary to prevent failures from negatively impacting the customers that make SpaceX viable as a company is both a rational and ethical strategy.

Returning to current events, the Falcon 9 intended to launch Intelsat 35e went horizontal on July 4, and is likely now in the integration facility present at LC-39A, providing easier access to engineers as they comb over the vehicle to ensure its health. After an absolutely picturesque launch attempt Monday evening, weather is looking even better for a potential launch attempt on either Wednesday or Thursday evening.

If the vehicle and pad cooperate, Intelsat 35e will be a facing send off for the Eastern Range before it shuts down for the remainder of July to undergo routine maintenance. SpaceX currently does not have Vandenberg (West coast) missions scheduled until August, so July will likely see no launches from the company. There is still plenty to be done in lieu of launching customer payloads, however. LC-40, the pad damaged in the Amos-6 static fire incident last September, is currently preparing to be reactivated, with a recent interview of Gwynne Shotwell pointing to its initial availability sometime in August. Once it is reactivated, all single core Falcon launches will be transferred to LC-40, and LC-39A will begin undergoing structural modifications to accommodate both crewed missions in 2018 and Falcon Heavy, which could debut as early as Q4 of 2017.

The two most visible changes that will occur at LC-39A will be the installation of additional hold-down clamps and modifications to the Transporter Erector, as well as a Crew Access Arm, which will be attached to the large, vertical structure seen directly right of Falcon 9. Of note, it is very likely that at least two, if not all three of the first Falcon Heavy’s cores are already present at the Cape. After years of being deemed a paper rocket, Falcon Heavy is indeed very real and very close to being able to conduct its first launches.

A month of no launches from SpaceX will undoubtedly be less than thrilling, but the Air Force and Kennedy Space Center employees will get a much-deserved break from a busy launch manifest ahead of what will likely be an even busier final four months of the year. There is a lot to look forward to.

WATCH: SpaceX Starship Flight 10 launch

Published

SpaceX is set to launch its tenth test flight of the Starship program, with a launch window that will open at 6:44 p.m. local time, or 7:44 p.m. on the East Coast.

Starship’s tenth test flight was originally scheduled for launch yesterday with a one-hour window that opened at 7:30 p.m. ET, but it was called off 17 minutes before that window even had a chance to open.

Starship Flight 10 rescheduled as SpaceX targets Monday launch

SpaceX moved the flight to tonight. It was also originally scheduled to have a launch window at the same time as Sunday, but it was pushed back 14 minutes to around 6:30 p.m. ET. There are storms in the area, as well as clouds over Starbase, so there is the off chance for another launch delay.

There are several big objectives for this launch, including the expansion of the operating envelope for the Super Heavy booster. SpaceX says there are “multiple landing burn tests planned.”

The booster will also be performing a few in-flight experiments to help with data collection. Specifically, real-world performance data on future flight profiles and off-nominal scenarios will be on the list of things SpaceX will be looking for.

Starship itself will have a few in-flight objectives that include the deployment of eight Starlink simulators that are similar in size to the next-gen satellites for the internet service. SpaceX was set to test this with Starship’s seventh test flight, which occurred in January 2025. However, the task was abandoned as the vehicle was destroyed before deployment could occur.

Liftoff conditions are currently looking favorable, and SpaceX will be eager to improve upon its Starship launch program as CEO Elon Musk has big plans for it in the coming years.

Starship Flight 10 rescheduled as SpaceX targets Monday launch

SpaceX said it is now targeting Monday evening for Starship’s 10th flight test.

SpaceX stood down from its planned Starship Flight 10 on Sunday evening, citing an issue with ground systems. 

The launch attempt was scheduled during a one-hour window that opened at 7:30 p.m. ET, but it was called off just 17 minutes before the window opened. SpaceX said it is now targeting Monday evening for Starship’s 10th flight test.

Flight 10 rescheduled

A lot of excitement was palpable during the lead up to Starship Flight 10’s first launch window. After the failures of Starship Flight 9, many were interested to see if SpaceX would be able to nail its mission objectives this time around. Starship itself seemed ready to fly, with the upper stage being loaded with propellant as scheduled. Later on, SpaceX also noted that Starship’s Super Heavy booster was also being loaded with propellant.

However, 17 before the launch window opened, SpaceX noted that it was “standing down from today’s tenth flight of Starship to allow time to troubleshoot an issue with ground systems.” Elon Musk, in a post on X, further clarified that a “ground side liquid oxygen leak needs to be fixed.” Musk did state that SpaceX will attempt Flight 10 again on Monday, August 25, 2025.

Starship and SpaceX’s development goals

The fully integrated Starship system is the tallest and most powerful rocket ever built, standing over 400 feet when stacked. Composed of the reusable Super Heavy booster and the Starship upper stage, the vehicle is central to SpaceX’s long-term ambitions of lunar and Martian missions. NASA has already selected Starship as the crewed lunar lander for Artemis, with its first astronaut landing mission tentatively set for 2027, as noted in a Space.com report.

So far, Starship has flown nine times from Starbase in Texas, with three launches this year alone. Each flight has offered critical data, though all three 2025 missions encountered notable failures. Flight 7 and Flight 8 ended in explosions less than 10 minutes after launch, while Flight 9 broke apart during reentry. Despite setbacks, SpaceX has continued refining Starship’s hardware and operations with each attempt. Needless to say, a successful Flight 10 would be a significant win for the Starship program.

SpaceX Starship Flight 10: What to expect

SpaceX implemented hardware and operational changes aimed at improving Starship’s reliability.

SpaceX is preparing to launch the tenth test flight of its Starship vehicle as early as Sunday, August 24, with the launch window opening at 6:30 p.m. CT. 

The mission follows investigations into anomalies from earlier flights, including the loss of Starship on its ninth test and a Ship 36 static fire issue. SpaceX has since implemented hardware and operational changes aimed at improving Starship’s reliability.

Booster landing burns and flight experiments

The upcoming Starship Flight 10 will expand Super Heavy’s flight envelope with multiple landing burn trials. Following stage separation, the booster will attempt a controlled flip and boostback burn before heading to an offshore splashdown in the Gulf of America. One of the three center engines typically used for landing will be intentionally disabled, allowing engineers to evaluate whether a backup engine can complete the maneuver, according to a post from SpaceX.

The booster will also transition to a two-engine configuration for the final phase, hovering briefly above the water before shutdown and drop. These experiments are designed to simulate off-nominal scenarios and generate real-world data on performance under varying conditions, while maximizing propellant use during ascent to enable heavier payloads.

Starship upper stage reentry tests

The Starship upper stage will attempt multiple in-space objectives, including deployment of eight Starlink simulators and a planned Raptor engine relight. SpaceX will also continue testing reentry systems with several modifications. A section of thermal protection tiles has been removed to expose vulnerable areas, while new metallic tile designs, including one with active cooling, will be trialed.

Catch fittings have been installed to evaluate their thermal and structural performance, and adjustments to the tile line will address hot spots observed on Flight 6. The reentry profile is expected to push the structural limits of Starship’s rear flaps at maximum entry pressure.

SpaceX says lessons from these tests are critical to refining the next-generation Starship and Super Heavy vehicles. With Starfactory production ramping in Texas and new launch infrastructure under development in Florida, the company is pushing to hit its goal of achieving a fully reusable orbital launch system.
