Title: Mission: Moon
1Mission Moon!
2By 2018 humans will be living and working on the
Moon at a lunar outpost!
3What is it like on the Moon?
4What is it like on the Moon?
- Length of Day
- Atmosphere
- Temperature
- Water
- Radiation
- Gravity
- Landscape
5Long Days and Long Nights
- The Moon spins on its axis rotates once every
27 days - Earth rotates once every 24 hours
- The Moons rotation means its day is almost two
weeks long and then its dark for two weeks!
6Nothing to Breathe
- The Moon does not have an atmosphere
- Atmospheres are important because they protect us
from harmful solar radiation and help to keep
temperatures
7Really Hot and Really Cold
- The Moons temperatures range from 107 C in the
sunlight to 153 C in the shade or darkness
(thats 224 F to 243 F below freezing!) - The temperature changes so much because there is
no atmosphere to moderate it. - Extreme changes are bad for equipment.
8Water?
- There is no liquid water on the Moon.
- There may be frozen water ice in deep craters
near the poles.
Oh no.
9Sunscreen, Anyone?
- Solar radiation levels on the Moons surface are
dangerously high because there is no atmosphere
to block incoming radiation.
10High Jump!
- The Moon is smaller than Earth, but because it
has mass, it DOES HAVE GRAVITY! - The Moons gravity is 1/6 of Earths.
- Because there is less pull on you, you will
weigh less and jump higher on the Moon!
11Dusty!
- The Moons rocks have been pulverized into a fine
powder by continuous asteroid impacts. - This regolith layer can be 45 feet thick!
12Lunar Landscape
Bright, heavily cratered, Lunar Highlands
terrae. Mostly plagioclase rocks that are about
four and a half billion years old! Dark, smooth
Lunar Lowlands maria (mar-e-uh). Made of 3 to
4 billion year old basalt the same rock type as
Earths ocean floor and the Hawaii volcanos.
Lunar Regolith covers much of the surface.
Lunar Highlands
13What will we need to live on the Moon?
14What will we need to live on the Moon?
- Shelter
- Power
- Food
- Water
- Earth communications
- Tools / equipment
- Ways to move around
15Shelter
- A lunar outpost is needed for long stays to
maintain an atmosphere and protect us from
temperature extremes space suits protect us
outside the base. - It will be built with materials transported from
Earth (costly!) but we can use lunar resources
Moon to help (titanium, regolith for lunar
bricks!). - A natural shelter can be found in the lava tubes
in ancient volcanic areas.
16Power
- Fuel is expensive to transport from Earth
- Solar power can be used to run an outpost.
- Solar power will have to be stored in costly
batteries for long periods of darkness, unless
the base is in a permanently sunny region.
17Food
- Food will be transported from Earth. Eventually,
hydroponic gardens will be created to provide
food for the outpost.
18Water
- Liquid water does not exist on the Moons
surface. - Water ice may exist in deep, permanently shadowed
craters at the poles. - All humans need water to drink. Water also can be
broken into hydrogen and oxygen and used as a
fuel or to create an atmosphere at the enclosed
base.
19Calling Home
- Earth is far away about 240,000 miles away!
- We will need to communicate about outpost
operations and the health of the astronauts, and
we will want to stay in touch with Earth friends,
too! - The outpost will have to be in constant view of
Earth to maintain communications. If the outpost
is not in view, costly satellite systems will
have to be put in place.
Note Astronauts Do Not Use Telephones!
Communications travel by radio waves, part of the
electromagnetic spectrum!
20Tools and Equipment
- We will need to transport tools and equipment to
the lunar outpost to build the base and conduct
scientific experiments.
21Roving the Surface
- We will need ways to move around the surface as
we build the outpost, search for resources, and
conduct scientific experiments.
22Apollo 15 Landing Site
Topography
A lunar outpost will have to be built in a safe,
relatively flat location that is easy to reach on
foot or by Moon buggy.
23Other Considerations
- What science can we do? Depending on where we
go, we can learn different things about how the
Moon formed and has changed. We can set up
telescopes - to monitor Earth
- or to look deep
- into space.
24When we select a lunar outpost site, we need to
consider all of these things!
- Shelter
- Power
- Food
- Water
- Earth communications
- Tools / equipment
- Ways to move around
25Were Going to the Moon Again!
- The Apollo missions helped us learn much about
the Moon, but the missions were short and in only
a few places.
26Were Going to the Moon Again!
- By 2018, we will have a permanent lunar outpost
on the Moon that will permit people to live and
work there for long periods of time. - How old will you be? Do you want to go?
27Were Going to the Moon Again!
- This will help us prepare for exploration of Mars
and beyond by helping us create the technology
needed to support space flight and habitation,
and helping us understand the impact of space on
the human body.
28The Lunar Reconnaissance Orbiter Mission Will
Help!
29The Lunar Reconnaissance Orbiter Mission Will
Help!
- LRO spacecraft launches in Fall 2008
- It will orbit the Moon for a year, collecting
data to - Characterize solar radiation on the lunar surface
and how it might impact humans and materials - Make a high resolution global, 3-D map of the
Moons surface so we can select landing sites - Make very detailed maps of the Moons resources
and the Moons polar regions to see if water ice
is present.
30- Mission Moon!
- Just like NASA teams of scientists and engineers,
you and your team will propose a site for a
future lunar outpost and debate why it should be
chosen. - Your Mission
- Review the data for the different possible lunar
outpost sites - Select the site that has the fewest risks and
most benefits in your view
