SMS 4x More Expensive Than Data From Hubble

paradoxSpirit writes "Physorg has a paper comparing the cost of text messaging versus the cost of getting data from Hubble Space Telescope. From the article: 'The maximum size for a text message is 160 characters, which takes 140 bytes because there are only 7 bits per character in the text messaging system, and we assume the average price for a text message is 5p. There are 1,048,576 bytes in a megabyte, so that's 1 million/140 = 7490 text messages to transmit one megabyte. At 5p each, that's £374.49 [$732.95] per MB — or about 4.4 times more expensive than the 'most pessimistic' estimate for Hubble Space Telescope transmission costs." "Hubble is by no means a cheap mission — but the mobile phone text costs were pretty astronomical!""

"160 characters, which takes 140 bytes because there are only 7 bits per character in the text messaging system,..."

WTF?

Also, they don't seem to account for any headers or other transmission overhead? Where'd these guys come from, the Verizon School of Mathematics?
