Mission insignia

In December 2010, the Head of the Russian Federal Space Agency, Anatoly Perminov approved the patch of the Soyuz TMA-21 mission. The patch was designed based on a drawing by young artist Marciel Santos Kayle, a 12 year old from French Guiana

. According to a Roscosmos news release, Marciel’s sketch was chosen for the crew patch, since it depicts Gagarin and his crew vehicle Vostok.
The spacecraft will fly a drawing of Gagarin, and, apart from being called Gagarin, it will also be written on the spacecraft.

Kvant-V equipment glitch

During the launch processing in March 2011, the Technical Management on Human Space System Flight Testing reported an operational glitch of the Kvant-V equipment. The Kvant-V system resides in the Instrumentation Propulsion Module - one of the three modules that make the Soyuz TMA-21 spacecraft. On March 13, Roscosmos Board held a meeting to discuss the issue and delayed the launch from March 30, 2011. The glitch was traced back to a faulty part (capacitor) in the equipment. Russian Space Agency Roscosmos established a working group with representatives from RSC-Energia and TSNIImash, the manufacturers and developers of the Soyuz systems. Proposals of the working group were considered during an additional General Designers’ Review led by RSC-Energia president Vitaly Lopota. After analyzing the submitted data by the Review, Roscosmos decided to set April 4 as the new launch date.

Pre-launch processing

The Soyuz TMA-21 spacecraft arrived at Baikonur Cosmodrome on February 9, 2011. On the same day, the RSC-Energia technicians, tested the spacecraft's Kurs system.

Crew training

Roscosmos' Gagarin Cosmonaut Training Center (GCTC) hosted a two-day exam session for the prime and backup crews of Soyuz TMA-21 on March 4-5. On March 4, the prime crew of Samokutyayev, Borisenko and Garan were tested through integrated training in the ISS simulator and their backup crew of Shkaplerov, Ivanishin and Burbank were tested in the Soyuz mockup. On the next day, the crews were swapped and examined. The two groups of crews successfully passed the exams after solving all the tasks for which they were examined. Anatoly Perminov, the head of Roscosmos hosted the traditional tea-party with Soyuz TMA-21 prime and backup crews on March 11. On March 17, cosmonauts and astronauts left GCTC for Baikonur. On March 19, Roscosmos Board gave its final approval of the crews to go through training at the Baikonur Cosmodrome.

Samokutyayev, carried a small stuffed dog given to him by his daughter. Hanging in front of the crew, live NASA TV launch footage showed that the dog begun to float as the spacecraft soared skywards, an indication of the weightlessness of space. "Launch was great, and we are in orbit and we are doing great," said Samokutyaev after the launch. Replying back the Moscow Mission Control said "This is a great anniversary flight, and have a great one".

Hatches between the Soyuz TMA-21 and the ISS were opened at 2:13 UTC on April 7. The three Soyuz crew members floated into the ISS. They were welcomed aboard for a crew greeting ceremony and a mandatory safety orientation by Expedition 27 Commander Dmitry Kondratyev and Flight Engineers Catherine Coleman and Paolo Nespoli.

Return to Earth

 on August 24.

The Soyuz TMA-21 spacecraft undocked from the International Space Station on September 16, 2011 at 00:38 UTC. Due to an apparent communications malfunction, voice communications from the crew were lost shortly after the deorbit burn, prompting some tense moments on the ground, but otherwise the reentry and descent went perfectly. There was no immediate explanation for the communications drop out.

Soyuz Commander Aleksandr Samokutyayev and Flight Engineers Andrei Borisenko and Ronald Garan returned to Earth on 16 September 2011 at 03:59 UTC, landing on target in central Kazakhstan. Russian search and rescue teams, along with NASA flight surgeons and space station program managers, were standing by to help the Soyuz crew. Three Antonov airplanes, 14 Mi-8 helicopters, and seven rescue vehicles took part in the search for the capsule. Samokutyayev was the first to be extracted out of the Soyuz descent module, followed by Garan and Borisenko. All three appeared relaxed and in good health as they rested in recliners near the descent module. After quick medical examinations inside a nearby erected tent, the crew were flown to Karaganda
