I'm sure it helps that software probably accounts for way more of what used to be hardware, so they can switch screens and stuff faster.

You would think that they would have some better quality cameras available for the video.

Spent it all on the space truck

How do the parachutes not all get entangled with each other?

Not compared to the datalink hardware required to send Near Real Time HD video hundreds of miles over the air...

I would have settled for 640x480. I'm pretty sure some of that stuff was like 25x25.

Besides, they managed to do it OK to show the Roadster getting launched into space.

The forces that keep the parachutes open makes them somewhat rigid. Since the cords are all the same length, the fabric parts bounce off each other. Additionally, the cords themselves create a somewhat rigid cone due to tension. They can't twist around another cone, because as soon as you increase the tension on one side, it causes the whole thing to want to spring back the other way.

It has to do with airflow coming off the outside of the parachutes. They do actually bounce off each other but the air coming off the outside keeps them separated for the most part. If you watch this video starting about 23:25 you can see them deploy and bounce off each other. Since the capsule isn't turning they don't get intangled. If the capsule was spinning they would wrap around each other.

They also use historical data from lots of testing. We have been using chutes for cargo drops for quite a while. This PPT shows some of that testing data and the understandings of multi-chute behavior we get from testing (slide 35 / collisions).

SpaceX just did a test hop of SN5 and it was badass!!

Today's Starlink 10/SkySats 19-21 launch marks the successful reuse of a falcon 9 booster for the sixth time. The same rocket has launched six different payloads into space.

Refueling in space sounds fun.
