The licence has been approved, the NOTAM and marine warnings published, closure announced.

Fish and Wildlife's comments were published yesterday. I gather that the document was deleted from the original location, but as I recall, it was pretty much copied and pasted into the body of the final FAA determination WRITTEN RE-EVALUATION OF THE 2022 FINAL PROGRAMMATIC ENVIRONMENTAL ASSESSMENT FOR THE SPACEX STARSHIP/SUPER HEAVY LAUNCH VEHICLE PROGRAM AT THE BOCA CHICA LAUNCH SITE IN CAMERON COUNTY, TEXAS. I remember the bit about "Per the table above, an average summertime thunderstorm at Boca Chica would deposit more water over the landscape than any single or all combined activations of the deluge system".

 

The Hyperbola-2 methane-liquid oxygen reusable verification stage rose to a height of 178 meters during its 51-second flight. It performed a powered descent and soft landing, supported by four landing legs. The 3.35-meter-diameter, 17m-long test stage is powered by a variable thrust Focus-1 engine.

The vertical takeoff, vertical landing test marks progress towards a reusable medium-lift rocket to debut in 2025. It is also the latest marker in Chinese efforts to emulate the success of SpaceX and its Falcon 9 rocket.

 

Tory Bruno spoke.

“If I were buying a space business, I’d go look at ULA,” Bruno said. “It’s already had all the hard work done through the transformation. You’re not buying a Victorian with bad plumbing. It’s all been done. You’re coming in at the end of the remodel, so you can focus on your future."

I have some skepticism.

 

[insert obvious comments here]

 

In an Oct. 9 letter to the FAA and Congress seen by SpaceNews, SpaceX principal engineer David Goldstein said the report relied on “deeply flawed analysis” based on assumptions, guesswork, and outdated studies.

The article contains details.

In 2021, the FAA commissioned the Aerospace Corp., a federally funded nonprofit focused on space, to provide a technical assessment of the rise of LEO constellations and the risks posed to aviation and people on the ground by unplanned and controlled reentries of these satellites and the upper stages that launch them.

Someone from Aerospace mentioned the difficulties in such an estimate, and Goldstein's letter points out more problems.

Update at https://blogs.nasa.gov/spacestation/2023/10/09/international-space-station-operations-update/

Roscosmos confirmed that the observed leak is on Nauka’s backup radiator, which is mounted to the outside of the module. The radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April. The primary radiator on Nauka is working normally, providing full cooling to the module with no impacts to the crew or to space station operations.

Teams on the ground will continue to investigate the cause of the leak, and additional updates will be made as available.

 

At about 1 p.m. Central,

ISS: In the last few minutes, MCC-Houston asked the ISS crew to go to the cupola and look for any signs of "flakes" toward the aft of station; Jasmin Moghbeli reported "yeah, there's a leak coming from the radiator on MLM;" the MLM is the Russian Nauka multi-purpose lab module

 

Good analysis, from all I've heard.

Anyone who keeps track of Elon Musk knows the world's richest man has a penchant for setting aspirational schedules for his companies....So, if you have an opportunity to interview him, why spend time asking Musk to prognosticate when one of his companies will do something years in the future?

and

SpaceX's brilliant engineers certainly have creative ideas and novel plans to get Starship to the Red Planet, so why not ask Musk about them when you have him for a rare hourlong one-on-one conversation? It's the how that is most interesting now, not the when or why, especially for an audience interested enough to tune in at the IAC.

and

But Mowry's questions missed the mark at a time when the Starship program is at a critical point, and he didn't probe with follow-up questions to tease out more insightful answers.

The whole article is worth a read, really.

 

Well, that was an unimpressed review from Eric Berger, though Bob Smith has stuff to be unimpressed about. Eric also mentions Glassdoor reviews, an ex-employee group letter, and anonymous citations of current and former employees.

the company's new chief executive will be Dave Limp, who stepped down as Amazon's vice president of devices and services last month.

The significance is as u/Obvious_Parsley3238 pointed out: "250k last march, 1 mil last december, 1.5 mil in may, 2 mil now".

I chose the title because I thought and hoped it's a reasonable inference.

As an example, the first time I booked my own air flight -- actually, every time -- I made sure it was a ticket for the days and places I want, and that I got to my home at the end.

Do you know more about this Varda licensing situation? Is it possible to get a re-entry licence before launch? If they could have, they're incompetent not to. If not, that seems like a ridiculous regulation, requiring someone to launch with no confidence that they can legally come back (and possibly still incompetence on Varda's part for not making sure all the conditions were going to be met).

[–] pigeonberry@lemmy.world 1 points 1 year ago

As You999 put it, "the laws of the country that the craft is registered still applies". I hadn't heard the term "the Chicago Convention". I've heard only "The Outer Space Treaty", or formally Treaty on principles governing the activities of states in the exploration and use of outer space, including the moon and other celestial bodies. Specifically Article VIII:

A State Party to the Treaty on whose registry an object launched into outer space is carried shall retain jurisdiction and control over such object, and over any personnel thereof, while in outer space or on a celestial body. Ownership of objects launched into outer space, including objects landed or constructed on a celestial body, and of their component parts, is not affected by their presence in outer space or on a celestial body or by their return to the Earth. Such objects or component parts found beyond the limits of the State Party of the Treaty on whose registry they are carried shall be returned to that State Party, which shall, upon request, furnish identifying data prior to their return.

Could Varda actually land the capsule? I presume so (the whole thing is a moot point if they can't). Would the FAA (and, for all I know, other agencies) land on them like a pile of bricks? I certainly hope so!

 

I love this video.

 

I'd seen the story about a spacecraft making a drug in microgravity and planning to land it in the US.

However, the recovery of Varda's capsule is on hold after the Federal Aviation Administration and the US Air Force recently declined to give Varda approval to land its spacecraft in a remote part of Utah. TechCrunch first reported the FAA turned down Varda's application for a commercial reentry license.

"Varda Space Industries launched its vehicle into space without a reentry license," an FAA spokesperson told Ars on Wednesday. "The FAA denied the Varda reentry license application on September 6 because the company did not demonstrate compliance with the regulatory requirements."

Some are suggesting: lit all too well, like sparks and flames and kabooms and all.

The FAA has repeated multiple times: there is no launch licence yet for a second launch. Since the FAA asked the Fish and Wildlife Service to look into the matter, I think it's highly unlikely that the FAA would issue the licence before FWS says it's O.K.

I don't know that there has been a definitive statement of the exact ending date. The Xeet summary provided included "The FWS has up to 135 days to submit the final biological opinion to the FAA (Started in August)." If it's 4 months including weekends and holidays, it could be up to December 1 to December 31ish. But it could be handled before then, or if the FAA agrees, the deadline could be extended, or maybe it's working days only. Also, the FAA would likely need time to digest it and issue its own ruling.

But there have been other reports that the FAA hopes to be done with it by October. So maybe they have inside knowledge.

I posted here about the FWS environmental re-assessment due to the booster bidet.

 

I don't have a transcription to hand and shouldn't take the time to do it myself. The image alone:

https://nitter.net/pic/orig/media%2FF6VfGnVWYAAB5tv.jpg

The FAA asked the Fish and Wildlife Service for "re-initiation of Endangered Species Act consultation" due to the booster bidet. FWS has 135 days to give a final biological opinion.

I'm sorry, but I don't follow what you're referring to. I think the new render is near the top, showing Starship and Super Heavy stacked. I didn't look at the page before, so I don't know what else might have changed.

[–] pigeonberry@lemmy.world 2 points 1 year ago

Just wanted to point out a glamor video of Starlink deployment.

[–] pigeonberry@lemmy.world 2 points 1 year ago

Eric Berger quoted a tweet from the FAA here, but it was in the form of an image. A text transcript was kindly provided by World Spills @WorldSpills here:

SpaceX conducted a test flight of the Starship/Super Heavy at Boca Chica, TX on April 20, 2023. As a result of that launch, SpaceX completed a mishap investigation with FAA oversight; this investigation analyzed the launch, mishap events, and corrective actions. Before it is authorized to conduct a second Starship/ Super Heavy launch, SpaceX must obtain a modified license from the FAA that addresses all safety, environmental, and other regulatory requirements. As part of that license application determination process, the FAA will review new environmental information, including changes related to the launch pad, as well as other proposed vehicle and flight modifications. The FAA will complete a Written Reevaluation (WR) to the 2022 Programmatic Environmental Assessment (PEA) evaluating the new environmental information, including Endangered Species Act consultation with the U.S. Fish and Wildlife Service. If the FAA determines through the WR process that the contents of the PEA do not remain valid in light of the changes proposed for Flight 2, additional environmental review will be required. Accordingly, the FAA has not authorized SpaceX's proposed Flight 2.

It was followed by untranscribed

The FAA will provide updates with notification of any license determination or results of additional environmental review.

When the major problems from your first test can be illustrated by Heath Ledger in 2008 -- debris zoom but boom no boom -- it's not surprising.
