The first leg of the journey for Aalto-2, launched to space from Florida on Tuesday evening Finnish time, is now safely over. The International Space Station robot arm received the Cygnus cargo spacecraft carrying Aalto-2 and dozens of other small satellites at 1.05 pm Finnish time, after which it was installed in the Station鈥檚 Unity module in the docking port facing Earth at 3.39 pm on Saturday 22 April.

The robot arm was operated by US astronaut Peggy Whitson from NASA and French astronaut Thomas Pesquet from ESA.

鈥業 am glad that I could be a part of docking the Cygnus cargo spacecraft to the Space Station and welcome the QB50 satellites. They will be sent into space in May. One of them is Aalto-2 鈥 the first satellite from Finland! I am very pleased that another European Space Agency member state is becoming 鈥渁 true space nation鈥濃, greeted Pesquet.

鈥楾he Aalto-2 satellite will now spend a few weeks at the Space Station and wait for its turn to be launched. As the plan stands now, the small satellites will be detached to their orbits either on 8 or 15 May鈥, says Aalto Professor Jaan Praks, who is in charge of Aalto satellite projects.

Aalto-2 and other small satellites will take part in the international QB50 Mission, the aim of which is to produce the first ever comprehensive model of the features of the thermosphere, the layer between the Earth's atmosphere and space. When launch time comes, the astronauts will install the launch adapter into a robot arm, which will allow the satellites to be safely detached to their orbits.

鈥楾he astronauts will film the satellite being detached and that will be the last time we get to see the Aalto-2 satellite before starting to wait for a signal from it鈥, says Tuomas Tikka, Aalto-2 team Quality Manager, and the current leader of Reaktor Space Lab.

Aalto's other nanosatellite, Aalto-1, will be launched from India with a PSLV rocket in the last week of May.
