SpaceX’s Crew Dragon and Falcon 9 Block 5 rocket are almost ready for astronauts

In a Commercial Crew update presented by Program Manager Kathy Lueders to the NASA Advisory Council (NAC), the agency has confirmed that SpaceX is deep into the final stages of hardware preparation and testing ahead of their first uncrewed and crewed demonstrations launches of Crew Dragon.

Barring a miracle for Commercial Crew Program partner Boeing’s Starliner spacecraft program or serious faults leading up to SpaceX’s own debuts, SpaceX is all but guaranteed to become the first private company in history to design, build, and launch a spacecraft into Earth orbit with real astronauts onboard.

SpaceX’s DM-1 Crew Dragon (serial number C201; “C” for capsule, “2” for Dragon 2, and “01” for capsule #1) capsule is already in Florida at one of the company’s spacecraft processing facilities, while that vehicle’s trunk segment – a module mounted below the capsule responsible for providing power (solar arrays), thermal regulation (radiator panels), and external cargo lift capacity – is scheduled to ship from Hawthorne, CA to Florida by the end of September. Demonstration Mission-1 (DM-1) is currently targeting a launch debut no earlier than November 2018.

DM-1’s Falcon 9 launch vehicle, booster B1051 and an expendable second stage, are also making significant progress towards the Crew Dragon’s uncrewed debut launch. NASA’s report noted that B1051 was on track for shipment (presumably to the Cape) sometime in the fall (technically anytime after August 31st) and that the upper stage would likely find its way to Florida soon after, sometime in September. Due to the fact that Merlin Vacuum engine qualification has not yet been completed, that milestone is likely the only thing standing between S2 shipment to FL, as SpaceX typically builds and tests both Falcon 9 segments near-simultaneously.

 

Meanwhile, SpaceX has successfully completed a duo of unique and critical tests of Crew Dragon’s parachute systems, carrying a Crew Dragon mass simulator (i.e. boilerplate) up to 45,000 feet (13,700 m) under a huge balloon before dropping the mockup, a test series designed to prove out the ability of the parachute system to successfully deploy and function in the exact flight regimes the real hardware will experience while safely returning astronauts to Earth. As NASA Commercial Crew Program Manager Kathy Lueders herself noted, that type of testing is extremely difficult to pull off, but SpaceX has thus far completed two.

On the launch pad side of things, SpaceX will be exclusively conducting Crew Dragon missions from Pad 39A. The company completed installation of a strikingly modern-looking crew access arm (CAA) just days ago, marking a crucial milestone for the historic launch complex to be truly ready to support human spaceflight once more, a heritage represented physically by the tower the arm is installed on (Shuttle-era) and the pad’s foundation and thrust diverter (constructed to support Saturn V’s Apollo moon missions).

Further down the road, SpaceX has already entered into the late stages of hardware integration and preparation for the second Crew Dragon demonstration mission (DM-2), which will almost without a doubt see SpaceX become the first private entity in history to build, launch, and operate a crewed spacecraft in Earth orbit.

According to NASA’s SpaceX-derived schedule, that particularly historic spacecraft is expected to be ready for launch as early as January, a full three months prior to its current April 2018 launch date. CEO Elon Musk did note recently on Twitter that the hardware for both crewed and uncrewed demonstration missions would “def[initely] be ready” for the launch dates of November 2018 and April 2019.

SpaceX and Elon Musk explain potential reasons for Starship loss

SpaceX and its CEO Elon Musk are starting to shed some light on the potential reasoning for the loss of Starship yesterday, which was lost after a successful launch and catch of the lower-stage booster.

Starship was lost during its ascension, and debris rained down over the Caribbean less than an hour after SpaceX lost all communication with the spacecraft.

A few hours after the launch was over, SpaceX started to shed some light after looking at preliminary data that the rocket left behind.

The company said that a fire developed in the aft section of Starship:

“Following stage separation, the Starship upper stage successfully lit all six Raptor engines and performed its ascent burn to space. Prior to the burn’s completion, telemetry was lost with the vehicle after approximately eight and a half minutes of flight. Initial data indicates a fire developed in the aft section of the ship, leading to a rapid unscheduled disassembly with debris falling into the Atlantic Ocean within the predefined hazard areas.”

Additionally, Musk said that there was some sort of oxygen or fuel leak in the cavity above the ship engine firewall.

The leak was evidently large enough to build more pressure than the vent was able to handle:

Some also seemed to recognize evidence of fires throughout the flight of Starship, which is obviously an anomaly:

There will be more information regarding the loss of Starship in the coming days and weeks, but Musk already believes that a bit of fire suppression and more volume in the cavity above the ship engine firewall could fix the issue.

“Nothing so far suggests pushing next launch past next month,” he said, so Flight 8 could happen sometime in February.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX completed its seventh launch of Starship on Thursday, accomplishing a clean liftoff and catch of the first-stage booster. However, the upper stage was lost after its ascent.

The launch took place just a few minutes after 5 p.m. on the East Coast, as the first attempts at getting Starship in the air for the seventh time were delayed by weather both last week and this week.

Conditions were favorable on Thursday as SpaceX looked to follow up a successful campaign by Blue Origin, Jeff Bezos’s company, earlier today.

SpaceX went into the seventh Starship launch with plans for a catch attempt of the first-stage booster, something it attempted and completed during the fifth test launch last year. It decided to skip a catch attempt with the sixth test flight as conditions were not aligned.

For now, SpaceX is extremely selective as to when it attempts catches.

However, it was successful during this attempt, its second completed catch:

This flight differed from previous launches as SpaceX rolled out several improvements to the rocket and the processes as it featured plans to do a Starlink deployment simulation and had various adjustments to flap placement and avionics.

These plans were disrupted by the fact that SpaceX lost all communications with Starship about ten minutes into the flight, which the aerospace company confirmed was a result of losing the spacecraft sometime during its ascent.

Although the catch was successful, the loss of the actual rocket seemed to be a huge damper on the entire event. SpaceX confirmed several minutes after the loss of communications that the rocket was destroyed and was lost.

It was its first failure since the second Starship launch in November 2023. SpaceX had no answers for why the rocket was destroyed and lost.

We will keep you updated in the coming days.

SpaceX confirms next Starship launch target – Here’s when it will take off

SpaceX has confirmed a new target date for the seventh Starship test launch after weather in Texas delayed the first scheduled date for “three or four days.”

The company is now targeting the launch for Monday, January 13, at 4 p.m. CST or 5 p.m. EST. The launch date is not set in stone as any variety of delays could impact this, but SpaceX hopes to finally take off after a delay that pushed it back from January 10.

What’s new with this Starship launch

With this being the seventh test launch of Starship, there are several things that the company will change and hope to accomplish. All of these launches are done in preparation for eventually taking flight to Mars, something that will happen next year, according to CEO Elon Musk.

First, SpaceX is rolling out a next-generation ship with “significant upgrades.” Forward flaps have been made smaller and are repositioned away from the heat shield, which will “reduce their exposure to reentry heating.”

SpaceX eyes 25 annual Starship launches starting next year

There is also a 25 percent increase in propellant volume, a new fuel feedline system for the Raptor vacuum engines, and a better-than-ever propulsion avionics module that will control the valves and reading sensors.

Avionics, as a whole, underwent a redesign and now have more capability and redundancy for missions as they become more complex.

Starlink test

SpaceX is also planning to deploy 10 Starlink simulators that are similar in size and weight to the next-generation Starlink satellites:

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.”

Ship return and catch

There will be several experiments that have to do with returning Starship and various catch scenarios and sequences. One of which will see “a significant number of tiles be removed to stress-test vulnerable areas across the vehicle.”

The ship’s reentry profile was also intentionally designed to test the structural limits of the flaps while at the point of maximum dynamic pressure during reentry.

Currently, SpaceX did not detail whether it would attempt another catch during this test launch. These are usually game-time decisions.
