Mercury 4

Flight MR4 – Liberty Bell 7

21 July 1961 

15 min 37s

Gus Grissom

This flight was planned as a repeat performance of Shepard’s which in fact it was – until just after splashdown, when the hatch of the Mercury craft blew open and seawater rushed in. As the capsule sank, Grissom was hauled to safety by a helicopter. He had nearly drowned. 

The astronaut, who admitted that he was a ‘little scared’ at lift-off – his pulse peaked at 171 – enjoyed the view out of his window; so much so that he was distracted from his work during the brief period of weightless flight. 

Liberty Bell 7 need not have sunk, despite shipping 2000 lb. of water. A warning light in the helicopter cockpit was false and the misinformed pilot ditched the spacecraft. Ironically, Liberty Bell was the lightest manned spacecraft, weighing 2836 lb in space.

Mercury 4 Stamps

Only five countries issued stamps to celebrate the flight of Mercury 4 with the first being five years after the flight. All of the countries celebrated Grissom’s flight on the anniversary of the flight or as a space achievements. Below is a list of the following countries that have issued stamps for Mercury 4.

Mercury 3 Mission Patches


Gus Grissom chose the name Liberty Bell because the capsule was shaped like a bell and because it carried stirring American connotations so important during the early days of the American space program. Like Al Shepard’s Freedom 7, not much creativity went into the logo for Liberty Bell 7. Chrysler-employee Cecelia Bibby did the artwork.

Below are Mercury 4 Mission Patches.
