Curiosity Mars Rover

Mars Rover Curiosity is lowered onto Planet Mars by the sky crane.

Curiosity begins it's exploration of Gale Crater on Planet Mars.

Curiosity rover is a robotic, car-sized Mars rover currently exploring Gale Crater, near the equator of Mars. The rover is a nuclear-powered, mobile scientific laboratory and part of NASA's Mars Science Laboratory (MSL) mission by the United States.

The MSL mission has four main scientific goals: investigation of the Martian climate, geology, and whether Mars could have ever supported life, including investigation of the role of water and its planetary habitability. Curiosity carries the most advanced payload of scientific equipment ever used on the surface of Mars.

Curiosity is the fourth NASA surface rover sent to Mars in 16 years, and is the heaviest robotic wheeled vehicle (at 900 kg) successfully deployed on a space mission, exceeding the 840 kg mass of the Soviet Union's Lunokhod 2 lunar rover from 1973.

The Royal Australian Navy Anzac-class frigate HMAS Perth

 HMAS Perth (FFH 157) is an Anzac class frigate of the Royal Australian Navy (RAN).

The last of the class to be completed, she was built by Tenix Defence Systems and commissioned into the RAN in 2006.

 In 2007, Perth became the first major warship of the RAN to be commanded by a woman. During 2010 and 2011, the frigate was used as the testbed for a major upgrade to the Anzac class' ability to defend themselves from anti-ship missiles.

HMS Campbeltown was a Batch 3 Type 22 frigate of the British Royal Navy.

Built by Cammell Laird Shipbuilders Ltd. in Birkenhead, she was part of the third batch of Type 22s, which were considerably larger than their predecessors and incorporated more advanced weaponry after lessons learnt from the Falklands War. She was decommissioned on 7 April 2011.

Campbeltown's last deployment was a seven month tour from 2007-2008 in the Persian Gulf, where she operated in support of Operation Calash and Operation Telic.[3] In early 2004 the vessel was deployed as part of NATO's Standing Naval Force Atlantic. HMS Campbeltown entered refit in September 2008.

The ship's bell of the first HMS Campbeltown, a Second World War Town-class destroyer famous for her role in the St. Nazaire Raid, has been loaned from Campbelltown, Pennsylvania to the current Campbeltown for the duration of her Royal Navy service.

The Royal Navy announced in March 2011 that the Campbeltown would be decommissioned on 7 April 2011. She paid a final visit to her namesake town of Campbeltown, Argyll in March 2011 where a series of ceremonies, including a town centre parade by the ship's crew took place to commemorate the end of the ship's active service.

Campbeltown made her final entrance to Plymouth on 31 March 2011 before decommissioning in a traditional ceremony on 7 April 2011.

The ship's bell has now been returned to Campbelltown, Pennsylvania. The ship's bell made specifically for the latest HMS Campbeltown was given to Campbeltown, Kintyre, to be displayed in the town's museum until a future Campbeltown is commissioned.
