This is all really good engineering but is also Magic.

Nope. Somebody say that difference between science and engineering is that engineering could be reliably applied to do things.

Is there any explanation what the fire on the side was, APU perhaps?

Very impressive.

Looks like there is still a bit too much heat coming through the aft wing hinge to be entirely comfortable, but it looks like they landed softly enough that if there hadn't been a post-landing explosion they might have been able to bring it in in one piece.

The first stage recovery was awesome, but the quick disconnect arm took a bit of a roasting.

Some quick analysis.

[rmgill]

They're not doing any regenerative cooling during re-entry. The fact it's all made of steel (stainless I think) helps for the durability. Composites would not handle that level of repeated heating. 

[TrustMe]

Would Titanium do better than steel it has better heat resistence?

B-58 and XB-70 were made mainly in stainless steel, so SS heat resistance should be enough.

Seems engines are made of copper and a nickel-copper alloy, a SpaceX-proprietary type of Inconel.

Harder to weld. Stainless is easy to weld and the point of the exercise is to get cost per unit down. He's building Saturn V sized F-150s not Ferraris.

Nice video with different angles of the landing booster

 

[TrustMe]

Thanks for the explanation guys.

For the memory of the recent space developments as seen 10 years ago...

That guy from Arianespace surely would want this video to be lost..

Richard Bowles, he is kind of famous

Starship flight 7, seemed a very good catch of the booster: however Starship itself dramatically lost towards the end of burn.

SMOD?

DOJ Moves to Dismiss Immigration Case Against SpaceX

By Aldgra Fredly

The U.S. Department of Justice (DOJ) filed a motion Thursday indicating it wants to drop a lawsuit accusing SpaceX of hiring discrimination against refugees.

The lawsuit filed by the DOJ in August 2023 alleged that SpaceX, owned by Elon Musk, violated the Immigration and Nationality Act by refusing to hire people with asylum or refugee status.

The aerospace company countersued the DOJ later that year on constitutional grounds. Last month, a federal judge in Texas granted the DOJ’s request to stay the lawsuit for 45 days, saying that the department lacks the authority to pursue its claims against SpaceX.

In a court filing on Thursday, the DOJ requested that the court lift the stay on the lawsuit so it could proceed with filing a notice of dismissal. It did not provide a reason for the possible dismissal.

Both the DOJ and SpaceX did not respond to a request for comment by publication time.

In its 2023 lawsuit, the DOJ alleged that between 2018 and 2022, SpaceX discouraged asylees and refugees from applying for jobs and failed to fairly consider their applications due to their citizenship status. The DOJ accused SpaceX of falsely asserting in job postings and public statements that export control laws hindered the company from hiring people without U.S. citizenship.

The company argued that due to the sensitive nature of its work—such as manufacturing technologies with military applications—it is subject to legal mandates under export control laws, including the International Traffic in Arms Regulations (ITAR), which limit whom it can employ.

“These export control laws and regulations are critical to our national security. Moreover, violating them can have severe consequences for a company like SpaceX,” it stated, noting that failing to comply with the regulations could result in hefty fines and criminal penalties.

On Aug. 25, 2023, Musk stated on the social media platform X that his company had been told that hiring anyone who is not a permanent U.S. resident would violate ITAR.

“We couldn’t even hire Canadian citizens, despite Canada being part of NORAD! This is yet another case of weaponization of the DOJ for political purposes,” he stated.

 

To give you an idea how strict ITAR is, Leupold hunting scopes are regulated by ITAR;

Leupold and Stevens riflescopes are controlled for export and import, by the U.S. Department of State under the International Traffic in Arms Regulations (22 CFR, Parts 120-130) and the Department of Commerce under the Bureau of Industry and Security Export Administration Regulations, EAR (15 CFR, Parts 730-774). Depending on what type of riflescope you are purchasing would determine what type of license is required. Our riflescopes are a restricted item and in order to ship from the U.S. you must comply with the regulatory license and documentation requirements.

A Canadian who drives down to Seattle and buys a 3x9X Leupold scope in a gun shop, then drives back to Canada, is committing a crime.

Now imagine if SpaceX hired a bunch of people with "asylum or refugee status" and placed them were they'd have access to launch technology, USAF payloads, etc.

Thank goodness we have a rocket company that can put LARGE payloads into earth orbit. 

Land a fueled thruster system on the asteroid.
Nudge it into a stable near earth orbit.
Mine it for Rare Earth Metals. 
Profit!

Given Bruce Willis' health issues, seems quite risky.
