		<description>You have some extremely flawed assumptions here. First you are assuming that a meteor shower hits the earth in equal portions throughout the earths atmosphere which is never the case... when is the last time that you saw a meteor shower take up more than a portion of the visible sky. Using your logic that would mean that there are then even less meteors to possibly hit the ISS which is absolutely wrong there are more. Why? Because we only see the meteors that hit our atmosphere. There may be many more meteors passing at say 350km</description>

		<description>Anyone who can do math can reasonably say that UFOs are pure fantasy.  The universe is not teaming with life.  Even if it was teaming with life, even IF it was, the vast distances between even neighboring star systems make regular visitations virtually impossible let alone even remotely practical.

Those who cling to UFO superstition ought to join their televangelist Christian brothers and sisters who sell miracle healing hanker-chiefs.  Just pray the right words and you will be healed of anything! even senseless superstitions!

Pareidolia is a powerful and deceptive mental faculty and everyone would do well to understand what it is and the tricks their own brains play on them.  The government isn&#039;t making cover-ups and telling you what to think, your brain does an excellent job of that without any help from the government.</description>

&lt;blockquote&gt;Re: BOLIDENATE… I second the comment from JSchu.  I checked several dictionaries but apparently “bolidenate” is NOT a word. Taking it in context here, it obviously means to make larger, since when I clicked the pic, I got a larger version of it.

Can this columnist, or perhaps Discover’s editors, please address this? I work as a professional copy editor &amp; proofreader, and consider myself a huge “word nerd,” so I have to say my curiosity is VERY piqued as to whether this is actually a new word, or if it’s just a typo. Either way, hope to hear from someone soon.

Cheers,
Shari K. in California&lt;/blockquote&gt;

Phil is a great proponent of neologisms.  They&#039;re all perfcectly cromulent.</description>

i uncapitalized your name for you. you is welcome.&lt;/blockquote&gt;

Wow, until I read this I never realised how amazing I am, being able to hold down the &quot;shift&quot; key while typing a letter. . .

Seriously, is it so difficult for you to use good English?</description>

Yeah, right, as if NASA could prevent employees from publishing photographs online.</description>

Your thought process is correct, and very insightful. You are pondering orbital mechanics without the math. The piece you are missing is that the speed and energy of your spacecraft is proportional to your orbital altitude. At the altitude of a space shuttle, orbital speed is on the order of 18,000 mph or more. Therefore, the vehicle must decelerate by 18,000 mph to come to rest on a runway in Florida. Now, you COULD theoretically use the space shuttle engines to do all of the decelleration down to terminal velocity, so that you essentially fall straight down into the atmosphere as you speculated. However this would require an amount of energy equivalent to that used to get the space shuttle UP TO that speed in the first place. IE, two solid rocket boosters and a full external tank of fuel for the space shuttle main engines. This is logistically improbable, if not impossible. therefore, mission designers only slow down the spacecraft enough for the orbit to intersect the atmosphere, and let the friction do the rest.

Hope that helps!
