This morning I watched the splashdown of the Artemis One spacecraft. I had a link to the live feed in my morning news from
the Washington Post. It was most inspiring. And yet, I still felt
an emotional sadness of the event. As the coverage continued from
when I connected to the link, the news person was saying how there
was some number of minutes until the spacecraft was to enter the
Earth's atmosphere. It would be traveling at over 25,000 mph when
it started to descend.
In an attempt to put that into some kind of perspective. Think of
it like this. When you're outside in the winter and you want to
warm up your hands. One way of doing this is by briskly rubbing
your hands together. The friction of your palms rubbing past each
other creates a small amount of heat. Now even if you might be
doing this really, really fast. You are probably now moving your
two hands any faster than five or ten mph relative to each other.
So the amount of heat you are generating at that speed is enough
to slightly warm your hands.
It is the heat of that friction that I want to focus on here. The
heat generated at five to ten mph compared to the heat that is
generated at 25,000 mph. The amount of heat generated is probably
comparable to that at the surface of the sun. And yet, some very,
very smart people have figured out a way to address this problem
and protect the spacecraft. The friction of the spacecraft hitting
the atmosphere slows down the forward velocity of the craft. The
by-product of that friction is the amount of heat generated. I
think that is just staggering that we have figured out a way to
manage that problem.
Then, a bit longer into the coverage of the splashdown, the news
person announces that the spacecraft has passed through the "blackout" phase of re-entry and radio contact with the spacecraft has
resumed. A few moments later, the news person informs that the drone chutes have opened and are slowing the spacecraft's speed of descent.
He said the velocity of the spacecraft was now traveling at ONLY 259 mph.
Now, before I continue, think back to your days in high school. Back to seeing those videos
where you would see the crash tests of vehicles being done at 40
mph or 50 mph. Remember seeing the dummies in the car flinging
forward on impact? Now think about how that would feel going from
150 mph to 0 in about 1 second. That's the kind of shock on the
body that occurs during an opening of a parachute. It's very
survivable, but it's something you will never, never forget. I
know this personally. Because I felt that when I did a parachute
jump when I was in the Navy. Which is a long story I could tell
you another day.
Now back to the re-entry news. A camera was mounted inside
a part of the Artemis spacecraft that looked into the compartment
where the parachutes were located. From that camera, we could see
the main canopies deploy and snap open. I think there may have
been a video feed delay from that camera because the video of the
chute opening seemed jilted. Sort of like a series of stills
instead of a smooth continuous motion.
The coverage continued with actually seeing the splashdown and
recovery. Which, I think was nice but, a little less dramatic.
The announcer then went on to say how this was another historic
moment that demonstrated how when we put our best and our
brightest to the task. We can achieve great things. It was at that
point when I felt that tug on my emotions. It is true that when we, as a people, work together, can achieve great things. When we think things through using reason and logic, we really can achieve great things.
Earlier this week Janet and I watched the recently released movie
"Good Night Oppy." It's a movie about the Spirit and Opportunity
Mars rovers. If you liked the movie Big Hero 6. You are sure to
like the movie Good Night Oppy. I would give it an enthusiastic
two thumbs up. Below is a link to the trailer of the film on
YouTube.
Good
Night Oppy
You can stream the full movie on Amazon Prime video. Although, be
warned. You may, as with me, feel that same emotional tug that I
felt at the end. Seeing how we, as a people, actually can achieve
great things. But I don't think the numbers are on our side for
how it will go for us. The number of smart people is
overwhelmingly shadowed by the "not-so-smart" people.
The ones who believe the elections are fake if they don't win.
The ones who believe there is a deep state of lizard people who
eat babies. The ones who believe in Q anon. The ones who believe that only white Christians should be in power in our country and/or the
world. Personally, I think white supremacy is just a form of white
fragility. They would rather put down some demographic rather than
do something to elevate themselves. It's the path of least
resistance for them.
Then there are the ones who believe climate change is fake. The
ones who believe vaccines plant mind-controlling chips in our
brains. I could go on and on and on. But, I'm sure, you've heard of
all this and probably a lot more.
It is when I weigh what we have done and can do against the
things so many would rather believe. It is that, that make me feel sadness. It is that other part of our population who would rather choose to believe it's not their fault their lives are so miserable because it
conveniently gives then an easy out. It is when I see that, my feelings of joy are deflated when I see that we can do great
things. I wish it were different. But, wishing won't change the
way things are. My optimism is slipping away for humanity. The
numbers just don't seem to be on our side.
