Moon videos
(i.e., Moon
videos):
High cal ones:
- Neil Armstrong - First Moon Landing 1969 | 2:29:
Neil Armstrong (1930--2012) first steps on
the Moon.
Yours truly saw this live on
TV in
1969.
Ah, the good old 1960s.
A few seconds is good for the classroom.
- Apollo 11 on the Sea of Tranquility | 3:10:
The color-poetic version of Apollo 11
with Neil Armstrong (1930--2012),
Buzz Aldrin (1930--),
and Michael Collins (1930--)
(not seen in the video).
A minute or two is good for the classroom.
- APOLLO 11
Official Trailer | 1:52: The
documentary.
OK for the classroom.
- KAGUYA taking "Full Earth-rise" by HDTV (Apr. 5, 2008) | 1:15:
A full "Earthrise" observed by
the orbiter
spacecraft
SELENE (AKA Kaguya, 2007--2009)
(launched by
Japan Aerospace Exploration Agency (JAXA))
while orbiting
the Moon in
2008.
It's all real, but it looks so phony.
Why?
Well, the image makers can always enhance colors
to bring out features in digital images.
But more basically, space
has NO air no soften
the edges of objects.
Everything looks sharp, there's NO
sfumato.
Also space is just very, very
black,
the Moon is just
grey,
and the Earth is
celestial sphere of
blue and
white.
Good for the classroom.
- KAGUYA taking around the landing site of the Apollo 15 by HDTV |
0:52:
Japan Aerospace Exploration Agency (JAXA)
A flyover of the Moon by
the orbiter
spacecraft
SELENE (AKA Kaguya, 2007--2009)
(launched by
Japan Aerospace Exploration Agency (JAXA))
featuring
the near side of the Moon,
Mare Imbrium,
crater Aristillus,
crater Autolycus
(named for Autolycus of Pitane (360?--290? BCE)
and NOT for the grandfather
Ulysses,
Autolycus (Wolf Himself, Very Wolf)),
Rima Hadley,
the Apollo 15
landing
site,
and
Montes Apenninus.
It's all real, but it looks so phony.
Why?
Well, the image makers can always enhance colors
to bring out features in digital images.
But more basically, space
has NO air no soften

Impact on the Moon during the 2019jan21 total lunar eclipse: very high-sensitivity camera | 0:36:
The
2019jan21 lunar impact event
happens at 0:05 in the
video where arrow points.
The flash is emitted by the hot gas
created as impactor
kinetic energy
is converted into heat energy
which in turn vaporizes
rock to
said hot gas.
Such impact events
on the Moon
are NOT rare, maybe as often as every day
(see Nadia Drake, 2019jan24, SciAm, "In a First, Earthlings Spot a Meteor Strike
the Eclipse-Darkened Moon.
Data from Zuluaga et al. 2019
and
Wikipedia:
2019jan21 total lunar eclipse: Impact event sighted:
- The impact event was just
south of Crater Byrgius
which near the southeast limb
of the Moon
east of Mare Humorum
(see
moon_map_side_near_topographic.html).
- Flash: total
electromagnetic radiation (EMR) energy: ∼ 10**7 J
emitted over 0.30 s.
- impactor
angle
from the ground: < 35.6°.
- impactor
velocity: 13.8(7.3) km/s.
- impactor
kinetic energy:
0.9--1.8
TNT equivalent.
- Size scale: 0.3--0.5 m.
- mass: 20--100 kg.
- impact crater
diameter: 7--15 m.
- Can we find the
impact crater?
Probably NOT soon. It's pretty small and NO
spacecraft is looking at the moment.
Good for the classroom.
- Apollo 15 Hammer and Feather Experiment | 1:27:
On the
lunar surface
near Rima Hadley,
Apollo 15 Commander
David Scott (1932--)
using a hammer
and a feather
verifies Galileo's (1564--1642)
discovery
that all objects in a uniform gravitational field
free fall with
uniform acceleration.
See Wikipedia: Free fall: History, but
actually the free-fall result was mentioned
in passing by Domingo de Soto (1494--1560)
in a
In VIII libros physicorum (1545)
a commentary
on Aristotle's (384--322 BCE)
Aristotelian Physics
(see How Modern Science Came into the World, 2011, p. 90 by
H. Floris Cohen (1946--)).
OK for the classroom if one skips to the 55 second mark.
Low cal ones:
- Earthrise: the Recreation | 6:53:
A recreation of Earthrise
by William Anders (1933--2024)
on Apollo 8,
1968 Dec24:
We came to explore the Moon
and we discovered the Earth.
Too long for the classroom.
- Le voyage dans la Lune, Melies, 1902 | 8:24:
Where
scifi films began
Georges Melies (1861--1938)
and
Le Voyage dans la lune
(A Trip to the Moon) (1902 film).
Not worthwhile for the classroom.
- Cloudy Moon over Windy Forest | 10:00:09:
In slow TV, nothing happens.
