In memoriam of the first moonwalker, Neil Armstrong, today’s fun fact is about the moonwalkers:
Nine manned missions to the moon have taken place since 1968 when the Apollo 8 mission was launched, and all have been undertaken by the United
States. Of those missions (Apollo 8, 10-17), six (Apollo 11, 12, 14-17) landed on the moon. The following is the list of people who have been to the moon (meaning they have at least been in orbit around the moon), in order of date orbited, then rank for mission. Those marked with an asterisk (*) walked on the moon during the indicated mission, those marked with a caret (^) are appearing on the list for a second time.
Apollo 8: Commander Frank Borman II
Command Module Pilot James Lovell Jr.
Lunar Module Pilot William Anders
Apollo 9: Commander James McDivitt
Command Module Pilot David Scott

Sharks are arguably the oldest family of large animals still alive, with the oldest accepted shark fossil being about 420 million years old, predating the dinosaurs, land animals, and even land plantlife. Sharks as a group have survived four major mass extinctions, each of which had killed at least 70% of all species then living on the planet. Sharks have a great sense of smell, able to detect blood in a concentration of one part per million (for every drop of blood, there are 1 million drops of water), and they have another sense called electroreception, which allows them to detect Earth’s magnetic field…and any movement of nearby prey. Only four shark species (great white, tiger, bull and oceanic whitetip) produce a significant number of fatal shark attacks. Sharks in general, and those four in particular, are the top predators of their environment, and like many other natural hunters, are curious of unfamiliar creatures (read: humans). However, they lack any means to explore the unknown other than their mouth, which can explain some shark attacks considering humans are generally not sufficient prey to warrant feeding as a reason to attack. On average, there is less than one death from a shark attack each year while there are, on average, forty deaths from lightning strike. Finally, the eggs of the grey nurse shark hatch inside the mother and when the first embryo develops, it eats its sibling’s embryos and any unhatched eggs. Talk about sibling rivalry.
Today’s fun fact is from the original Facebook posts:
The national bird of the United States, the Bald Eagle, can be found in the wild in any state except Hawaii. With a range that stretches from Alaska, though Canada and the Lower 48, and into Northern Mexico, the population of the Bald Eagle is thriving and was removed from the Threatened Wildlife lists of the Lower 48 states in June 2007. The nests of Bald Eagles can weigh up to 1 ton, and are the biggest of any North American bird. The Bald Eagle’s Eurasian cousin, the White-tailed eagle (which resembles the Bald Eagle, but with a brown head), can typically be found in North and East Europe, but has pocket ranges from Greenland to Japan and from Iran to Russia. On average, the White-tailed Eagle is slightly larger than the Bald Eagle, but lacks the distinction of being a national symbol.
