AMSAT has put together a "how to" for ARISSat-1 at http://www.amsat.org/amsat-new/ARISSat/ARISSatHowTo.php

Two Russian cosmonauts will leave the confines of the International Space Station on Aug.3 to move a cargo boom from one airlock to another, install a prototype laser communications system and deploy an amateur radio micro-satellite.

Expedition 28 Flight Engineers Sergei Volkov and Alexander Samokutyaev are scheduled to venture outside the Pirs airlock at 10:30 a.m. EDT Wednesday to begin the six-hour excursion. Both spacewalkers will wear Russian Orlan-MK spacesuits. Coverage of the spacewalk will be broadcast live on NASA Television beginning at 10 a.m. EDT.

Shocking that we're already hearing about this considering the ISS isn't even finished with construction yet.

The International Space Station (ISS) will be de-orbited and sunk in the Pacific Ocean after 2020 like its Russian predecessor Mir, Russian Space Agency (Roscosmos) Deputy Head Vitaly Davydov said on Wednesday.

"We will be forced to sink the ISS. We cannot leave it in orbit as it is a very complicated and a heavy object. There must be no space waste from it," Davydov said in an interview posted on the Roscosmos website.
