A Russian Soyuz spacecraft failed to dock with the International Space Station Saturday.

The craft was carrying a humanoid robot that was scheduled to conduct a mission on the station with the cosmonauts who are there.

NASA said on its blog that the docking system of the Soyuz spacecraft failed to properly lock onto its target on the ISS.

The Soyuz has backed away from the ISS while the cosmonauts work on the station’s docking system.

In a first, NASA has demonstrated the first coordinated manoeuvre between two tissue box-sized water-powered spacecraft in the low Earth orbit.

The twin spacecraft were orbiting Earth about 9 km from one another, Universe Today reported on Friday.

The two spacecraft established a radio frequency communication cross-link to “talk” with each other.

One spacecraft issued a command to the second to activate its thruster and close the gap between the two. The fuel tanks on both the spacecraft were filled with water, NASA said.

During this propulsive manoeuvre, the water was converted into steam by the thrusters to propel the spacecraft.

“Demonstrations such as this will help advance technologies that will allow for greater and more extended use of small spacecraft in and beyond Earth-orbit,” said Roger Hunter, Programme Manager of NASA’s Small Spacecraft Technology Programme.

The demonstration conducted in late June was designed with a series of safeguards to ensure that only a pre-planned and authorised manoeuvre could take place.

While it was choreographed by human operators on the ground, the demonstration shows it is possible for a series of propulsive maneuvers to be planned with onboard processing and executed cooperatively by a group of small spacecraft.
