A somewhat obscure anniversary for the 15th is the first electrical welding during an EVA, according to Roskosmos:
Electrical welding was first performed in space 25 years ago by Svetlana Savitskaya and Vladimir Dzhanibekov, Russian cosmonauts. They spent 3.5 hours in outer space cutting and welding pieces of metal. The universal space welding machine was designed by Electrical Welding Institute, Kiev. For more than 10 years, the scientists were developing this complicated instrument.
Today the cosmonauts involved in this first space welding attempt tell about their experience.
“It was easy due to 0-gravity”, says Svetlana Saviskaya. “However, many people thought that we had made a special performance, that we hadn’t been working in space. Like with the first step on the Moon.”
“In outer space, with this invisible ray, it was a real miracle,” adds Vladimir Dzhanibekov.
The machine was tested deeply, but the developers could not define its behaviour in space precisely.
Specialists of the Kiev institute are still sure that their instrument will be used in future. The first welding in space opened one more page in the space exploration history.
Today Russian cosmonauts and scientists from Kiev recollect their past achievements and the time when Russia and Ukraine were conquering space together…

STS-127 Atlantis launched at long last on its 6th attempt. More segments for the Japanese Kibo module will be installed, and two crewmembers will swap places (Koichi Wakata down; Timothy Kopra up). With 6 people on board going up or down at different times on different spaceships, keeping track of them all can be confusing!
