Pushing Space Frontiers

The European Space Agency (ESA) announced it had shut down its Rosetta probe (picture) for two and a half years– leaving it mute and undisturbed until closer to its rendezvous with far-off comets.

The three-tonne craft launched in 2004 obtained gravitational boosts from Earth and Mars, to set it off on its journey of ten years, and over seven billion kilometres.

With surveillance and communications systems closed down, it is being kept warm by solar panels.

An on-board alarm clock will shake it awake in January 2014, a few months before meeting Comet 67/P Churyumov-Gerasimenko  – some 675 million kilometres out.

The craft has been controlled through NASA stations at Canberra and New Norcia, Western Australia; its mission is to send a probe onto the comet surface, looking for ancient matter, and new clues to the early construction of the universe.

The voyager mission was launched by the United States in 1977.


Back on Earth, preparations continue for the last of the Space Shuttle missions.

The shuttle Atlantis is set for launch on 8.7.11 to take supplies and equipment to the International Space Station.

Five of the vehicles were constructed for the National Aeronautics and Space Administration, beginning flights in 1981; the program ending a year after its planned termination date last year.

Two of the craft were lost in tragic accidents, in 1986 and 2003; the three remaining ones will po to museums.
