US Moon Flags Photographed



NASA has released  photographs showing that  most of the flags placed by crews of the Apollo spacecraft are still standing on the Moon. Shadows cast by five of the six US flags put up in the 1960s and 1970s are visible on the surface of the Moon. The Apollo 11 flag was knocked over as the Apollo 11 craft began ascending from the surface.

Mark Robinson, an investigator with the Funar Reconnaissce Oribiter Camera (LROC), said: "From the LROC it is now certain that the American flags are still standing and casting shadows at all of the sites, except Apollo 11.

The flags may not have retained their vibrant red, white and blue colours though. Exposure to heat, cold and light may have caused them to fade, Dr Robinson added.

Well there you have it. I doubt that the "hoaxers" will believe a word of it but then they are a bunch of arseholes

Move over John Innes,

Having put hurt my back at the weekend trying to lug a 75litre bag of Levingtons multipurpose compost from the car to the greenhouse (I got nowhere near the greenhouse – the bag is still sat by the back door chuckling to itself, the bastard!), I am very, very keen to discover new sources of growing media for our seedlings and container plants. While choosing smaller bags of compost may be the most practical option I am intrigued by research which may just have the answer to my prayers, Sadly the source of the miracle medium requires a slightly longer drive than the one from Hope Cottages to Roots and Shoots in Upminster,


It would seem that an ESA-linked team has shown that marigolds can grow in crushed rock very like the lunar surface, with no need for plant food. A team led by Natasha Kozyrovska and Iryna Zaetz from the National Academy of Sciences in Kiev planted marigolds in crushed anorthosite, a type of rock found on Earth which is very similar to much of the lunar surface. In neat anorthosite, the plants fared very badly. But adding different types of bacteria made them thrive; the bacteria appeared to draw elements from the rock that the plants needed, such as potassium.


Dr Foing, who presented the study at a recent European Geosciences Union meeting, said there was no reason in principle why the same idea could not bear fruit on the Moon itself. Tools could crush lunar rock and add bacteria and seeds. But, he added, scientists could look to go further, by selecting plants or bacteria that are especially well adapted to lunar conditions, or even by genetically engineering new strains.


There has been a revival of interest in Moon exploration in recent years. Europe's Smart 1 probe with its innovative ion engine ended its mission in 2006 with a deliberate crash onto the lunar surface. China's Chang'e 1 and Japan's Kaguya (or Selene) orbiters both began operations last year, while India's Chandrayaan 1 is due for launch within months. The US, meanwhile, is committed to putting human feet back on lunar soil by 2020.


ESA is not yet sure about further Moon missions; a decision on whether to proceed with a concept called Moon Next, which would probably deploy a roving vehicle in about 2015, will be taken later this year. Even if that gets the go-ahead, some ESA officials suggested that planting marigolds (or tulips or cabbages) would be unlikely to be part of the strategy.
