Astronauts complete walk

There were two astronauts teaching middle school children five years ago. They made a spacewalk together today. Their path cleared of junk that was threatening the space station and shuttle. Yesterday, the shuttle station place had too move out of the way of a four inch piece of junk. This junk had been projected to come close during the spacewalk. Astronauts Joseph Acaba and Richard Arnold II had no luck freeing up a stuck equipment storage shelf at the international space station. This was one of their main tasks. They used a hammer and were able to loosen a pin that they accidentally placed. This was the first time two former schoolteachers took a spacewalk together. This is their second time doing it. Their previous spacewalk were with other astronauts. They had fun doing this spacewalk together. Joseph and Richard were both in their forties. NASA picked them as educator astronauts in 2004 somewhere. The jammed storage platform was located on the left side of the space station that holds the solar wings. The space junk was a problem for the two hundred twenty mile high space station. The spacewalkers did move the equipment cart from one end of the space station to the other. This is all I know
