Photos: Atlas 5 rocket aims for International Space Station

Speaking publicly for the first time since a Falcon 9 rocket failure that destroyed a Dragon cargo capsule for the International Space Station, SpaceX founder Elon Musk said Tuesday that engineers are still piecing together what happened during the June 28 accident in hopes of announcing more details within a few days.

SpaceX will launch a space station-bound cargo ship with nearly 2.5 tons of supplies and experiments next Friday, Dec. 8, with a previously-flown Falcon 9 rocket booster after winning NASA approval for the reuse plan, agency officials said Wednesday.

Signaling strength in the international cooperation between the U.S. military and allied nations, a satellite funded by five countries will be launched by the Air Force on Saturday to codify a global communications deal.
