lake chad : africa

Lake Chad is a historically large, shallow, endorheic lake in Africa, which has varied in size over the centuries. Located mainly in the Southwest corner of Chad it extends in to Niger, Nigeria and Cameroon*

It is the remnant of a former inland sea, paleolake Mega-Chad. At its largest, sometime before 5000 BC, Lake Mega-Chad was the largest of four Saharan paleolakes, and is estimated to have covered an area of 1,000,000 km2 (390,000 sq.mi.), larger than the Caspian Sea is today.

Romans reached the lake in the first century of their empire. During Augustus times lake Chad was still a huge lake and two Roman expeditions were done in order to reach it. It was first surveyed from shore by Europeans in 1823, and it was considered to be one of the largest lakes in the world then. In 1851, a party including the German explorer Heinrich Barth carried a boat overland from Tripoli across the Sahara Desert by camel and made the first European waterborne survey. British expedition leader James Richardson died just days before reaching the lake.

ham the chimp : a day in history

After being captured by animal trappers, "Ham the Chimp" was sent to the Rare Bird Farm in Miami, Florida, where he was later purchased by the United States Air Force and brought to Holloman Air Force Base, New Mexico in 1959.

Two years later, on January 31, 1961 Ham was secured in a Project Mercury mission labeled MR-2 and launched from Cape Canaveral, Florida, on a suborbital flight as part of America's space program.

Less than 3 months later on April 12th, 1961, Yuri Gagarin became the first person to travel into space. 23 days after that historic flight (May 5th), Alan Shepard piloted the Mercury-Redstone 3 mission and became the second person, and the first American, to travel into space.

Ham's name is an acronym for the lab which prepared him for his historic mission — the (H)olloman (A)erospace (M)edical Center.
