Speaking at the 2019 AIAA Propulsion & Energy Forum, SpaceX Vice President of Build and Flight Reliability Hans Koenigsmann was significantly more confident that the company is just days or weeks away from wrapping up a serious Crew Dragon failure investigation.

On April 20th, flight-proven Crew Dragon capsule C201 experienced a catastrophic failure mode – largely a surprise to SpaceX – that completely destroyed the vehicle milliseconds prior to a planned static fire test. Given the obvious mortal danger such a failure would have posed to any crew aboard, SpaceX’s plans to conduct its first crewed Crew Dragon launch (Demo-2) in Q3 2019 were thrown out the window. Thankfully, Hans believes that SpaceX is just shy of concluding that investigation, “hopefully” permitting the launch of a critical abort test and Demo-2 before 2019 is out.

More specifically, Koenigsmann noted that SpaceX is currently planning to conduct a critical Crew Dragon in-flight abort (IFA) test in October or November, more or less in line with a recent report from NASASpaceflight.com that the test is targeted for November 11th, 2019. NASASpaceflight also confirmed that SpaceX still plans to fly Falcon 9 booster B1046.3 on the critical test flight, currently the only established plan to launch a thrice-flown booster, a potential first for SpaceX’s reusability program.

SpaceX’s IFA test is a continuation of the company’s suborbital Crew Dragon testing. Back in 2015, SpaceX successfully completed a pad abort test in which a low-fidelity Dragon mockup used its eight SuperDraco abort thrusters to replicate an escape from a rocket failure on the launch pad. SpaceX’s in-flight abort test will – like its namesake indicates – perform a similar test in flight, ensuring that Crew Dragon is able to safely escape from a failing Falcon 9 at Max Q, the point during launch where atmosphere-induced mechanical stress is at its peak.

In theory, demonstrating a successful pad and in-flight (Max Q) abort means that a given spacecraft is able to safely abort at all points during flight – from the pad all the way to orbit. It’s not clear if Crew Dragon is actually designed to be capable of what’s known as an “abort-to-orbit”, but the hardware is likely there if it’s needed.

On July 15th, Hans Koenigsmann and NASA Commercial Crew Program (CCP) manager Kathy Lueders went into significant detail with a preliminary Crew Dragon failure investigation update. They revealed that Crew Dragon’s April 20th explosion was traced to a likely mode, in which a “slug” of Dragon’s liquid oxidizer (nitrogen tetroxide, NTO) leaked and was subsequently smashed into a titanium valve by helium pressurized to several thousand PSI.

Said impact – effectively turning NTO into a bullet – thus created a spark in one or two ways: the titanium debris could have easily created sparks on its own, while NTO is also known to interact in violent and exotic ways with titanium under impact conditions. Either way, the fix is relatively simple (replace the valves and avoid titanium in the NTO pressurization system), but the fact that the design flaw existed in the first place serves as a much larger concern for the entirety of Crew Dragon’s joint SpaceX-NASA design and certification.

Ultimately, Hans seemed much more confident on August 19th than he was a month prior, indicating that the investigation is just shy of wrapping up. Once complete, SpaceX can complete the necessary modifications and get back on the saddle for Crew Dragon’s inaugural crewed launch and next abort test.

SpaceX scores another massive Pentagon deal to support military satellites

Published

By

SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.

The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.

SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.

With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.

Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.

Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.

Elon Musk sheds two new bits of detail on Starship after 13th test launch

Elon Musk shed two new bits of detail on Starship following its 13th test launch, which was an overwhelming success.

SpaceX launched Starship for the 13th time last Friday after two delays: one on Monday when several Raptor engines did not ignite, and another on Thursday due to unfavorable weather conditions in Starbase, Texas.

The launch was overwhelmingly successful. SpaceX was able to complete a necessary test of the heat shield tiles by increasing the acceleration of Starship from launch throughout the flight; 20 Starlink v3 satellites were released with no issue; the Super Heavy Booster landed safely in the Gulf of America, Ship successfully reignited engines while in space; and it also splashed down without incident in the Indian Ocean.

SpaceX Starship just nailed something it’s never done before

Nevertheless, more details are coming out about Starship, and Musk is doing the talking.

Starship Will Be Retrieved in the Ocean

Musk revealed on Tuesday night that Starship would be recovered by a ship in the Indian Ocean. SpaceX routinely tries to recover Starship after splashdown in an effort to find out more about the flight by examining the spacecraft afterward.

This helps engineers find out more about why things might have happened, allows them to examine any potential damage or anomalies that might have occurred, and increases the chances of an even more successful flight next time thanks to the additional information recovered.

Ship Could Have Been Caught by Tower Arms, Musk claims

Musk has already indicated that SpaceX will plan to attempt a catch of Starship with the 14th test flight. While this would be a major accomplishment, it would be an expected next step, considering the fact that the Super Heavy Booster has already been caught by the chopsticks on numerous occasions.

A ship catch would be a great indication of where SpaceX stands in terms of reusability and launch cadence. A successful catch with relatively no incidents would be a good sign that SpaceX is nearing a more frequent launch of Starship, but also that the reusability of the massive rocket would be something many would expect in the near future.

It is a necessity to make life multiplanetary.

Elon Musk updates the SpaceX timeline for Mars

Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.

The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.

Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”

Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.

Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.

SpaceX Board has set a Mars bonus for Elon Musk

In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.

The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.
