But why is that multi-step process even necessary? There should be an quick command-line utility to concatenate multiple video files according to exactly the timestamps the user ha…

I love FFMPEG, but it has truly awful handling of timestamps by default. You can't easily extract a clip using an exact timestamp because it rounds to the nearest keyframe, which m…

True. I've been considering signing up for Ars Pro because I like their content, but haven't yet been able to pull the trigger yet

I think it's reasonable to bring up the upcoming Artemis Human Landing System down select in the context of where Starship development is at.

Yes, it's unlikely that SpaceX will use the flip maneuver for humans any time soon. I believe they can just burn extra fuel margin to do a traditional vertical landing though. It c…

Maybe this article is filler, but Eric Berger is a well-respected veteran space journalist, and generally his articles on Ars Technica are great. He's just released a book on the e…

Good point on the carbon fiber thing. I forgot it's max operating temperature is 150 degrees Celsius (bursting to 180 degrees), while stainless steel can go to 820-870 degrees Cels…

Second stage reusability on the Rocket Lab Neutron will be much easier than the Falcon 9 because the carbon fiber frame doesn't need a heatshield. I may be wrong on this, but I bel…

By selling his houses in California and moving to Texas he reportedly will save billions in taxes.

Rocket Lab is an excellent company that makes innovative rockets: flying electric pump fed engines, carbon fiber frames and 3D printed Inconel engines all the way to orbit. They've…

Virgin Orbit launches their LauncherOne to orbit from a 747 Jumbo Jet. Virgin Galactic aspires to launches people for suborbital tourism on SpaceShipTwo. Different companies.

Fascinating comment! Thanks for sharing. Sucks for Red Dragon, but I'm looking forward to Starship!

Source? My understanding is Elon Musk believes blunt body re-entry vehicles landing with SuperDraco thrusters is the wrong architecture for Mars colonization, so all funding has be…

Musk has claimed imminent 24 hour turnaround times, Red Dragon on Mars every 2 years since 2018, second stage reusability etc. So it's acceptable to have some skepticism that Space…

Yes SpaceX's Raptor engines would be built in Hawthorne, CA and tested in McGregor, TX like the Merlin before it. But at Boca Chica, TX they are not just fitting the components int…

New Glenn is a case of "I don't have to outrun the bear, I just have to outrun you". The Atlas V and Delta IV Heavy are being phased out in favor of ULA's Vulcan (which uses its BE…

It looks like the National Security Space Launch (NSSL) Phase 2 Launch Services Procurement (LSP) contract that Blue Origin refer to was awarded in August 2020 (six months ago). ht…

> There is no VC who would have accepted a pre-SpaceX pitch for low cost launches, Starlink, or any of the rest of it. It would have been straight up "lol Iridium amirite, get out.…

> EASA has underestimated SpaceX from day one. EASA is the European Union Aviation Safety Agency. I think you meant to say ESA, the European Space Agency? But ESA's not that releva…

We know the Falcon 9's marginal cost for relaunch (with fairings reused is $15 million). Of this $10 million is for the second stage, $1 million is for booster refurbishment, the r…

After the massively incorrect analysis by popular YouTuber Thunderf00t, I made a video analyzing SpaceX's reusability https://www.youtube.com/watch?v=36o4UrS9OS4 It's 8 minutes but…

Because you've posted a link containing a lot of misinformation multiple times in this thread, I am posting this video correcting the misinformation: https://www.youtube.com/watch?…

The Thunderf00t video is wrong, see my video here: https://www.youtube.com/watch?v=36o4UrS9OS4
