|Progress M-17M mission completed.
On April 21, 2013 at 14:07 UTC the "Progress M-17M” unmanned supply spacecraft was deorbited. Non-burnt fragments of the spacecraft sank in the South part of the Pacific at 15:02 UTC.
|The US private space rocket launched for test mission.
On April 21, 2013 at 21:00 UTC the "Antares” rocket was launched from launch pad 0A at NASA's Wallops Flight Facility on the Virginia coastline, USA. The first launch of the Antares rocket is a major step in a joint venture between Orbital Sciences Corp. and NASA to develop two commercial space transportation systems to resupply the International Space station, replacing much of the cargo-carrying capacity lost when the space shuttle retired in 2011.
The rocket orbited a 3800 kg block of aluminum designed to mimic the mass characteristics of the Cygnus spacecraft, which will take the dummy payload's place on the next Antares launch.
The rocket also orbited 4 satellites of CubeSat standart: Alexander, Graham, Bell and Dove 1.
|Russia launches satellite with mice crew.
On April 19, 2013 at 10:00 UTC the "Soyuz-2.1a” rocket-carrier was launched from Baykonur Cosmodrome. The rocket orbited the ‘Bion-1M” biological satellite. Aboar the satellite there are over one hundred living creatures as its "crew". The 6300-kg Bion-M vehicle will return to Earth on May 18 after over 70 experiments. Aboard the Bion-M vehicle are mice, lizards, snails as well as strains of bacteria, plants and seeds.
The rocket has also placed six small communication satellites made in Germany, the United States, Republic of Korea on a near-earth orbit at an average altitude of 575 km.

|Russian cosmonaut Vinogradov became oldest spacewalker
On April 19-20, 2013 Russian cosmonauts Pavel Vinogradov and Roman Romanenko performed a 6 hour and 37 minute spacewalk.
The EVA was performed from the Russian "Poisk” module of the ISS. The hatches was opened at 18:03 Moscow time.
The spacewalk lasted longer than the initially planned six hours because during the installation of the Obstanovka experiment package on the station's Zvezda service module, one unit failed to switch on. Later the problem was solved.
Obstanovka will study plasma waves and the effect of space weather on the Earth's ionosphere.
The cosmonauts also retrieved the second container from the Biorisk experiment, which studied the effect of microbes on spacecraft structures, and replaced a reflector device that will facilitate the docking of the European Space Agency’s Automated Transfer Vehicle-4 when it arrives at the orbital outpost in June.
During a final task, Vinogradov, one of the most expe
