NASA has sent spacewalkers to look outside the international space station to find out why the solar power apparatus – which is used to create electricity for all of the life support systems – is damaged. Station Commander – Peggy Whitson and flight engineer – Dan Tani both went out today to find the source.

If you hate the bugs you find today than you’ll be glad that they are small compared to what they used to be hundreds of years ago. Germans uncovered a fossil claw that they believe belonged to what they think is the biggest bug that has ever been discovered.
This sea scorpion – Jaekelopterus rhenaniae – is as big as a large crocodile and seemed to be the worst predator in its day. They believe that it fed on fish and even killed its own kind. The find shows that arthropods—animals such as insects, spiders, and crabs, which have hard external skeletons, jointed limbs, and segmented bodies—once grew much larger than previously thought, said paleobiologist Simon Braddy of the University of Bristol in the United Kingdom.
Gray whales used to be some of the more popular whale species, but now they are quickly becoming scarce. There used to be three to five times more of them in the Pacific Ocean than there are right now. Researchers are thinking that the climate change may be the cause of this.
According to a recent census, about 22,000 eastern gray whales currently live in the Pacific. Experts had thought this to be around the whales’ natural population level, because of widespread die-offs of gray whales between 1999 and 2001 that plunged the animals to 18,000 individuals.
