It has come to my attention that some people think that the NASA lunar impact mission known as LCROSS seems to have a wide following of people who think that this will cause some kind of damage to the moon.
I know of one of these people personally.
A few facts:
FACT: The lander is about the weight of an SUV.
FACT: The Moon is about as massive as 1% of the earth.
FACT: If 100 SUVs fell from great height into the Nevada desert, all at once, it would barely measure on most seismographs.
FACT: Since the 1960s, nations around the globe have been landing and impacting probes of all kinds into the moon, including those both larger and smaller than this one.
FACT: Since the BEGINNING OF THE SOLAR SYSTEM the moon has been struck by objects ranging from pebble-sized to the size of mountains to the size of entire continents.
FACT: Even today, meteor impacts occur regularly.
FACT: The Moon is still there.
FACT: The Moon will remain there.
FACT: You moron.
There are other complaints, such as that it's unfair for us to experiment with the moon as it's not "ours". This is not true. The Moon belongs to "all mankind", although admittedly it's more like "all mankind that has access to large amount of rocket fuel". The knowledge gained by this experiment will most likely be information that can help all of mankind. It will be shared. Perhaps we will find water; if we do, that means that everyone- all of mankind (with rocket fuel,) will know that the moon can provide for further exploration. Theories will be redrawn and we will know more about how the solar system came into being.
The last and perhaps worst complaint about this mission is that it is too expensive.
NASA recieves about one half of one percent of the Govt. budget. The Department of Defense accounts for twenty one percent of the US budget.
In terms of dollars being converted into megatons, even if the entirety of NASA funding was funneled into this mission (which it is not; there are many other missions, research projects, and outreach programs that receive funding through NASA), then NASA blows up far less money than the DoD.
But efficiency isn't everything. And I'll admit that often we get little practical use out of of NASA projects. If you think that this means that NASA should not exist, however, then you are wrong.
To work, to eat, to sleep- this is to exist. We cannot exist without doing these things. But to learn, to play, to discover, to explore; these things are to live. If we do not do these things, then we might continue to exist- but not live.
And if you would rather exist than live, in exchange for one half of one percent more going to fund assault contractors, or street cleaning, or tax collection, then you aren't even alive right now.
