Mercury's interior is dominated by a large iron core whose radius is 1800 to 1900 km.
Its correct prediction of the motions of Mercury was an important factor in the early acceptance of the theory.
Mercury is the only body in the solar system known to have an orbital/rotational resonance with a ratio other than 1:1.

 Project Mercury History
The Mercury spacecraft was a cone-shaped capsule that held one astronaut and had a cylinder mounted to the top.
The blunt end of the capsule was a heat shield that protected the spacecraft from temperatures that reached 3000 F degrees during reentry into the atmosphere.
Purpose was to demonstrate primarily the structural integrity of the highest dynamic pressure anticipated during an Atlas launch for orbital flight.

Overall, the flight was highly successful: the Atlas booster performed well and demonstrated that it was ready for the manned flight, the spacecraft systems operated well, and the Mercury global tracking network and telemetry operated in an excellent manner and was ready to support manned orbital flight.
Mercury-Atlas 5 (MA-5), the second and final orbital qualification of the spacecraft prior to manned flight was launched from Cape Canaveral with Enos, a 37.5 pound chimpanzee, aboard.
An Atlas D launch vehicle lifted a Project Fire spacecraft from Cape Kennedy in the first test of the heat that would be encountered by a spacecraft reentering the atmosphere at lunar-return velocity.

Tests were conducted in 5 degree increments between 10 degrees to 30 degrees, and visually it appeared stability was better at the larger angle.
Between this date and December 5, 1959, the tentative design and layout of the Mercury Control Center to be used to monitor the orbiting flight of the Mercury spacecraft were completed.
An Atlas investigation board was convened to study the cause of the Mercury-Atlas 3 (MA-3) mission launch vehicle failure.

THE SUBORBITAL FLIGHT OF ALAN SHEPARD on May 5, 1961, was, in one sense of the word, anticlimactic.
The Mercury spacecraft was recovered 1 hour 25 minutes after the water landing, and Enos was recovered in seemingly excellent condition except that the extreme heat had obviously plagued him.[3]
In the Mercury-Atlas 5 (MA-5) orbital flight, Enos performed a complex multiple operant task as he twice orbited the earth.

Space Task Group officials expected delivery of the MA-5 launch vehicle, Atlas No. 93-D, about mid-August 1961, but it was decided by STG and the Air Force to delay shipment until the flight of MA-4.
Estimated temperatures during reentry should be about 3,000 degrees F on the heatshield, 2,000 degrees on the antenna housing, 1,080 degrees on the cylindrical section, and 1,260 degrees on the conical section.
The STG operation planners estimated that the spent Atlas sustainer engine would reenter the atmosphere after 9 1/3 orbits, a considerable change from their estimates for the descent of the MA4 rocket.

At the time of his flight, John was the oldest of the Mercury astronauts at 40, and after his USMC promotion, the most senior in military rank.
The guy was just a perfect PR guy, and for the most part, when the press came, they let him do most of the talking.
All of the Mercury astronauts included the number 7 in naming their spacecraft, as a show of unity and teamwork among the 7 astronauts.

Enos flew into space on board Mercury Atlas 5 in November of 1961.
Enos' flight was a full dress rehearsal for the next Mercury launch on February 20, 1962, which would make Lt. Colonel John Glenn the first American to orbit the Earth.

Mercury Atlas 2 (MA-2) was a sub-orbital test vehicle launch to check maximum heating and its effects during the worst reentry design conditions.
The trajectory was designed to provide the most severe reentry heating conditions which could be encountered during an emergency abort during an orbital flight attempt.
Further evaluation found that the spacecraft afterbody temperatures were somewhat lower than originally anticipated.
