That is 20:15 Today, in West Europe... Even better. ;-)

Bye, Wilfred.

Bye, Wilfred.

Which feed did you decide to watch? I watched a recorded copy of one with a young well-spoken lady introducing different engineers and asking good questions.

Sometimes they showed something that looked like a panel of different analog/digital meters. i wish they had kept those on the screen ALL the time in the lower third or something. The 7 minutes of terror didn't seem so terrifying without that.

Hello Wilfred!

I would have thought that they would.. maintain the gauges
on the screen all the time.

I think they want to cater for a wider audience, but don't
realize most of their viewers are more of the nerd kind,
that don't care to much of the people in the control room
and just want to see the figures...

Nah.. I think they screwed up. BUT, they did offer other
streams. If I remember correctly one of them was an
"interactive" thing that DID have the gauges on the lower part
of the screen, and the top was some kind of visualization of the
descent. They sometimes showed that one for a few seconds
during the stream that I was watching. But most of the time it
was just a view of the engineers sitting behind their consoles -
waiting.

Too bad they designed the jetpack to be discarded. Why
couldn't it be designed to land safely (farther away..

Weight. It costs a lot to put kilograms into space.

True enough. They probably had to work within certain initial
guidelines and cut back with things (lighter material, less
cables, etc) until they were within spec.

..And it did have a camera!

Yes.. I forgot about that.

It took a video of the whole landing procedure that will
be published later (probably because it is still being
transmitted to earth).

I saw the one pic showing the sky crane cables. That was a good
quality pic. I wonder what kind of bandwidth they have for
tranmitting video back to earth.

I was really impressed with the TRNS (terrain relative
navigation solution) radar, to scope out and select the best
landing spot and only having a few seconds to do that, and then
having the jetpack navigate to that spot.

Impressive!

I started downloading one of the recorded live streams (approx 2
hrs).. then changed my mind when the audio and view streams
didn't merge with youtube-dl. :( But the above file was all
that was needed.

It seemed like an exciting 3 minute ride.

I'm surprised that the module (before chute deployment) doesn't
start tumbling and turning during the fastest approach.

The heatshield shape is designed in such a way that it doesn't. They have experience with that since before the apollo program! ;)

Then, after the chute deployed, you could see a bit of a
swinging motion.

The images were fantastic. The very last few seconds looked
precarious when all the soil started to block the cameras
though.

That's how you know it's real! ;)


Bye, Wilfred.
