Australia from Space: Part 4

MORE WONDERFUL IMAGES of Australia’s coastline, courtesy of the European Envisat Earth-monitoring satellite. Envisat was launched in March 2002 and at 8.5-tonnes is one of the largest satellites ever put into orbit. It circles the Earth every 101 minutes from north to south.

Satellite image of the Great Barrier Reef

An Envisat MERIS image of the Great Barrier Reef centred on Cape York Peninsula. Taken on 19 August 2004, this MERIS Full Resolution mode images has a spatial resolution of 300 metres.

Satellite image of the Southern Great Barrier Reef

This Envisat image features the southern part of the Great Barrier Reef off Australia’s Queensland coast. It is the world’s most protected marine area, one of its natural wonders and a World Heritage site. Spanning more than 2,000 km and covering an area of some 350,000 sq km, it is the largest living structure on Earth and the only one visible from space. This image was acquired by Envisat’s Medium Resolution Imaging Spectrometer (MERIS) on 8 November 2010 at a resolution of 300 metres

Satellite image of the Northern Great Barrier Reef

Another view of the Great Barrier Reef. Australian researchers have discovered that Envisat's Medium Resolution Imaging Spectrometer (MERIS) sensor can detect coral bleaching down to 10 metres depth. This means Envisat could potentially map coral bleaching on a global scale. MERIS acquired this image on 18 May 2008, working in Full Resolution mode to yield a spatial resolution of 300 metres.

Australia from space

Astronaut photo of the Petermann Ranges

The Petermann Ranges span 320 kilometres from eastern Western Australia into southwestern Northern Territory. The Range has been classified as a site of National Significance and lies within the proposed Katiti-Petermann Indigenous Protected Area.

THESE AMAZING IMAGES of selected landmarks in Australia were taken by European astronaut Paolo Nespoli during his current six-month stay aboard the International Space Station (ISS).

The ISS circles the globe in every 91 minutes, with different parts of our planet’s surface visible underneath each orbit as the Earth rotates.

Astronaut photo of Prominent Hill Mine

Prominent Hill Mine is a gold, silver and copper mine in northwest South Australia. Currently owned and operated by OZ Minerals, sale of the mine to the Chinese company Minmetals Australia Pty Ltd was blocked by the Australian Government on national security grounds…the mine is located within a high-security military area.

Astronaut photo of Mount Conner

Mount Conner is a flat-topped mountain in the Northern Territory, rising 300 metres above ground level (or 859 metres above mean sea level). It is thought to be part of the same sub-surface rock substrate that lies beneath the more famous Uluru (Ayers Rock) and Kata-Tjuta (the Olgas).

Astronaut photo of Lake Gairdner

Lake Gairdner is a huge salt lake in central South Australia, about 450 kilometres northwest of Adelaide. It is approximately 160 kilometres long and 50 kilometres wide, and in some places the salt deposits are over a metre thick. When flooded, it is deemed the fourth-largest salt lake in Australia, and it has hosted numerous land speed record attempts.

Astronaut photo of Queensland's Sunshine Coast

Queensland's Sunshine Coast is an expanse of coastline north of Brisbane that takes in the towns Noosa Heads, Maroochydore and Caloundra.
