When Gus Grissom climbed into the cockpit of his Mercury spacecraft on the morning of July 21, 1961, he was ready for an adventure. Grissom’s Mercury mission (MR-4) was the second of the series, and like Alan Shephard before him, it was a sub-orbital lob. The Redstone rocket would take Gus and his spacecraft, dubbed Liberty Bell 7, above the atmosphere, but not quite fast enough to achieve orbit. The launch was on time and perfect, as was the short period of weightless flight, and re-entry through the atmosphere. Liberty Bell 7 deployed its main parachute as expected and landed within two miles of the Navy recovery team. Gus secured the spacecraft and waited to be rescued. However, without warning, the explosive hatch blew off and the spacecraft begin to take on water. Grissom escaped but nearly drowned in his spacesuit. Liberty Bell 7 filled with seawater and sank to the bottom of the Atlantic. It was the only NASA spacecraft ever lost at sea.

The Estes Mercury Redstone 4 is an impressive 1:34 scale model of the historic NASA spacecraft and rocket. The finished kit stands nearly 29 inches tall and features laser-cut, layered balsa fins and a molded plastic model of Grissom’s Liberty Bell 7 and it’s Launch Escape System (LES). The set of detailed water-slide decals even includes the distinctive white “crack” that Gus painted onto the side of his spacecraft to make it resemble the actual Liberty Bell. This Advanced kit is a “must have” for all serious model rocketeers! Put the Mercury Redstone 4 on the flight line and countdown to launch, and watch it reach altitudes up to 200 feet on a C6-3 engine. Rocket and spacecraft return together under a colorful 15 inch parachute, ready to prep and launch again.

As for the real Liberty Bell 7, in 1999 after resting silently beneath the Atlantic for 38 years, a recovery team located and raised the spacecraft from its 16,000-foot depth. Now restored, Gus Grissom’s once lost spacecraft is on display in a Kansas museum, a tribute to the memorable, early days of the U.S. space program.

Beautiful rocket

Love the look of this rocket. But the nose cone is a pain to build and a little flimsy. Everytime I launch it breaks. So I don't launch it anymore.

Consistently exceptional performer

As many have observed this kit has been around for a while. The plastic capsule version I have built, probably at least 150 times, even when it was out of production, and I managed to call Estes and buy up as many of the capsule kits that remained so that I could continue to build them and sell them on eBay as a completed model. I can still remember the first time that I flew one of these when I was 15. Went down to a small quarry at the end of the street set up a launch pad in the bottom and then climbed up, so that I was about 45 feet above the pad, and had my father press the button. Watching it rise up to I level and then continue into the sky was possibly one of the most amazing things I have done in modeling. I have built this kit straight out of the box, as mentioned, I have built it from an assemblage of parts, I have also added detail to it every way that you fly it will be enjoyable just don’t overpower it. The original took off slowly so emulating that produce the best launch experience

Built the first version of the Mercury Redstone 54 years

Built the first version of the Mercury Redstone 54 years ago. Have a new kit and ready to try building the new version.
