Great on Elon Musk and the SpaceX team, but the Commercial Crew program is how many years behind schedule? They've had how many launch failures in under a decade? Ambition shouldn't be harnessed, but focus on all ambitions shouldn't be lost either.

"This is, I think, the most inspiring thing I have ever seen," said Musk on Saturday (Sept. 28), admiring the 165-foot-tall (80-meter) Starship as it was lit by spotlights.
Glad to see you like what you paid for.

How many "launch failures" have SpaceX experienced in the first 11 years?

SpaceX has experienced four launch failures (three Falcon 1 and one Falcon 9) out of the 79 total launches the company has conducted since 2006. (It also experienced a pad failure and a loss of vehicle [Dragon] during a post-flight test.)

According to Musk, only about five percent of SpaceX's workforce is assigned to Starship and Super Heavy at current. He said the company's priority and resources are focused on commercial crew and Falcon 9 operations.

SpaceX now has a section of its website dedicated to Starship.
SpaceX's Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world's most powerful launch vehicle ever developed, with the ability to carry in excess of 100 metric tonnes to Earth orbit. Drawing on an extensive history of launch vehicle and engine development programs, SpaceX has been rapidly iterating on the design of Starship with orbital-flight targeted for 2020.

Has SpaceX moved their Starship test item from Cocoa to the cape yet?
SpaceX representatives declined to answer News 6's questions about how the private company will transport the spacecraft more than 20 miles between the two facilities or when the relocation will occur.
However, records obtained exclusively by News 6 reveal that in September the 180-foot-tall spacecraft could be towed along the State Road 528 Beachline Expressway before being placed on a barge in the Indian River for shipment to Launch Complex 39.

This photo taken Thursday afternoon shows the nose section to be in a less complete form (about 50%) than the images shown in the above news feed, and the below also shows a large number of circular segments place about the facility in what looks like enough to build another rocket.
This image led me to wonder if the nose section in the article had already been transported.
The new image also shows what looks to be earthworks constructed to make an access road out of the facility on the southern side.

SpaceX's Starship Mk1 burst its top during a cryogenic propellant load test at the company's Boca Chica, Texas launch site on Wednesday (Nov. 20).
This [Mk1] had some value as a manufacturing pathfinder, but flight design is quite different.

SpaceX statement
The purpose of today's test was to pressurize systems to the max, so the outcome was not completely unexpected. There were no injuries, nor is this a serious setback.
As Elon tweeted, Mk1 served as a valuable manufacturing pathfinder, but flight design is quite different. The decision had already been made to not fly this test article and the team is focused on Mk3 builds, which are designed for orbit.

Nice photos!
SpaceX confirmed last week that it has paused work on Starship at the Cocoa location and that the employees working there have been reassigned to either Boca Chica or other projects within the company in Florida. Work on the Mk2 vehicle (as seen in the above photos) has been halted in favor of the Mk3 build in Texas.
To that end, some parts from the Cocoa site were recently loaded onto a ship for delivery to Boca Chica.

SpaceX's stretch goal is to build one to two Starships a week, this year, and to pare back construction costs to as low as $5 million each, reports Ars Technica.
"The conventional space paradigms do not apply to what we're doing here. We're trying to build a massive fleet to make Mars habitable, to make life multi-planetary. I think we need, probably, on the order of 1,000 ships, and each of those ships would have more payload than the Saturn V—and be reusable."
Musk has thought about this a lot, obviously.
"The point at which one says the goal is to make life multi-planetary, it means that we need to have a self-sustaining city on Mars," Musk said. "That city has to survive if the resupply ships stop coming from Earth for any reason whatsoever. Doesn't matter why. If those resupply ships stop coming, does the city die out or not? In order to make something self-sustaining, you can't be missing anything. You must have all the ingredients. It can't be like, well this thing is self-sustaining except for this one little thing that we don't have. It can't be. That'd be like saying, 'Well, we went on this long sea voyage, and we had everything except vitamin C.' OK, great. Now you're going to get scurvy and die—and painfully, by the way. It's going to suck. You're going to die slowly and painfully for lack of vitamin C. So we've got to make sure we've got the vitamin C there on Mars. Then it's like, OK, rough order of magnitude, what kind of tonnage do you need to make it self-sustaining? It's probably not less than a million tons."

Starship has the capability to transport satellites, payloads, crew, and cargo to a variety of orbits and Earth, Lunar, or Martian landing sites. Potential Starship customers can use this guide as a resource for preliminary payload accommodations information. This is the initial release of the Starship Users Guide and it will be updated frequently in response to customer feedback.

SpaceX's Starship SN3 was lost in a cryogenic test early Friday morning (April 3). From Ars Technica:
This week, SpaceX workers in South Texas loaded the third full-scale Starship prototype — SN3 — onto a test stand at the company's Boca Chica launch site. On Wednesday night, they pressure-tested the vehicle at ambient temperature with nitrogen, and SN3 performed fine.
On Thursday night SpaceX began cryo-testing the vehicle, which means it was loaded again with nitrogen, but this time it was chilled to flight-like temperatures and put under flight-like pressures. Unfortunately, a little after 2am local time, SN3 failed and began to collapse on top of itself. It appeared as if the vehicle may have lost pressurization and become top-heavy.
Shortly after the failure, SpaceX's founder and chief engineer, Elon Musk, said on Twitter, "We will see what data review says in the morning, but this may have been a test configuration mistake."

The loss of SN3 was a configuration error, according to Elon Musk (via Twitter):
Good news is that this was a test configuration error, rather than a design or build mistake. Not enough pressure in the LOX [liquid oxygen] tank ullage to maintain stability with a heavy load in the CH4 [methane] tank. This was done with N2 [nitrogen].

For the first-time, a full-scale prototype of SpaceX's Starship vehicle, SN4, lit its engine on Tuesday evening (May 5), reports Ars Technica.
After ignition, it appeared that the Raptor rocket engine burned for about 4 seconds. At the end of this test at the South Texas Launch Site, the vehicle still stood. About 90 minutes after the test, SpaceX founder and Chief Engineer Elon Musk confirmed the test firing was good, saying, "Starship SN4 passed static fire."

On the same day (May 28) that SpaceX performed its fourth static fire with SN4, the Federal Aviation Administration (FAA) issued a license for the company to conduct suborbital reusable launch vehicle (RLV) missions.
Space Exploration Technologies is authorized to conduct RLV missions to launch the Starship Prototype Launch Vehicle. The RLV missions authorized by this license commence and conclude at the Boca Chica launch and landing site, Boca Chica, Texas.

Elon Musk has urged SpaceX employees to accelerate progress on its next-generation Starship rocket "dramatically and immediately," writing Saturday (June 6) in a company-wide email seen by CNBC.
"Please consider the top SpaceX priority (apart from anything that could reduce Dragon return risk) to be Starship," Musk wrote in the email.
In his email, Musk asked SpaceX employees to "consider spending significant time" in Boca Chica to help further accelerate Starship development. "For those considering moving, we will always offer a dedicated SpaceX aircraft to shuttle people."

Be it the unmanned Falcon 9 launches, the latest manned Dragon or this latest vehicle; no other space program provides the quantity and quality of video coverage (usually live) that we get from SpaceX.
The investment and commitment to not only obtain such a high level of video, but to share it with the public; is a credit to the firm's founder.
