ISS: Sputnik 3D printed satellite introduces itself from space

"This is the small spacecraft Sputnik speaking" were the first words transmitted by the 3D-printed satellite Sputnik from aboard the International Space Station, on Thursday.
Sputnik said that it was built at Tomsk Polytechnic University to commemorate the institution’s 120th anniversary.
The satellite is designed to orbit at 400 km (248.548 mi) after reaching the ISS. The operation is estimated to last about half year. The original satellite will be delivered to ISS on March 31.
The satellite will serve to test new technology in the field of space materials. It is equipped with sensors that will record the temperature of the parts that make up the satellite including the plates, batteries and board, while electronics data will also be monitored. The data will be transmitted to Earth where scientists hope to examine the condition of the satellite and how it holds up in the space environment. The findings will then be analysed and used to determine whether such material and techniques used to build the satellite could be transferred to the construction of larger equipment, such as space craft and shuttles.
