Tristan da Cunha, as seen from space

NASA imageThis view of Tristan da Cunha has been chosen as the Image of the Day feature on the website of NASA, the American space agency. It was taken by the crew of the International Space Station.  It shows that while volcanic eruptions are known to have occurred from the central crater, lavas have also erupted from vents along the sides of the volcano and from smaller cinder cones.

There’s much talk of St Helena becoming a holiday destination for astronomers, but on cloudy days, perhaps there’s an alternative possibility:

Cloud tourism.

An amazing array of stars can be seen in the island’s unpolluted skies. But when the clouds come, they can be a spectacle in themselves.

They blow with the wind as it swirls around the island’s high peaks and spins away into the distance.

It could be one of the wonders of St Helena. The only trouble is, you have to be very high up – in space, even – to get the best view. Perhaps the island won’t become a destination for cloud-spotters, after all.

It might not have been the best day for nude sunbathing. Beyond the stratosphere, the crew of the International Space Station were keeping watch on St Helena when they passed over the island on Wednesday, 18 July 2012.

Or trying to, anyway. The press release from NASA, the US space agency, doesn’t actually say whether the astronauts managed to pick out the island.

The crew travelled over Monaco, Mount Vesuvius in Italy, and the Seychelles – birthplace of Jonathan the tortoise.

Come mid-afternoon, they were under instruction to try to pick out the mountainous speck of St Helena.

The day’s report of activities on the space station notes that Charles Darwin had visited the island 176 years earlier. It says:

“St Helena Island, Atlantic Ocean (HMS BEAGLE SITE: Darwin and the Beagle arrived at St Helena Island on July 8, 1836 and remained for 5 days to explore its geology).

“Crew was to begin looking for this target a little early, if possible. Due to its remoteness and small size (47 square miles), there were no visual cues of the island during International Space Station approach.

“As the crew progressed on this mid-afternoon descending pass from the NW, they were to look towards nadir for this small island. There may have been a few clouds in the region, but they were to try for detailed shots).

St Helena Online has contacted NASA for an explanation of “look towards nadir” and to ask whether the astronauts did in fact spot the island. They may be a little too busy to respond…

  • Among the experimental equipment on board the space station is an aquarium. The expedition guide says: “Aquatic breeding over three generations, from fish parents to grandkids, previously impossible in space shuttle experiments, has become a reality. This allows, for example, viewing of the birth of space aquatic creatures that have never experienced the gravity force of Earth, and helps us understand how the space environment affects animals beyond generations in preparation for potential long-term space travel in future.”
