Mercury-Redstone 2 (MR-2) was the penultimate test flight of the Mercury-Redstone Launch Vehicle prior to the first manned American space mission in Project Mercury. It was launched at 16:55 UTC on January 31, 1961 from LC-5 at Cape Canaveral, Florida. Mercury spacecraft No. 5 carried Ham the Chimp, a chimpanzee, on a suborbital flight, landing in the Atlantic Ocean 16 minutes and 39 seconds after launch. ==Background==
The previous Mercury-Redstone mission, MR-1A, flew a trajectory that was too steep with accelerations too high for a human passenger. MR-1A had climbed to its programmed apogee of about 130 miles (209 km) and landed 235 miles (378 km) downrange. Mercury-Redstone 2 would follow a more flattened trajectory. Its planned flight path was an apogee of 115 miles (185 km) and a range of 290 miles (467 km).
