SpaceX CEO Elon Musk said Friday that the company was investigating a small leak in the rocket it plans to launch on Saturday. The entrepreneur later said that the launch was still planned, but that an "abort trigger" had been added.

Elon Musk: Investigating a (very small) leak in the upper stage. If ok, will launch tomorrow.

Elon Musk: Looks like we are go for launch. Added an abort trigger at T-60 secs for pressure decay of upper stage helium spin start system.

The rocket is scheduled to launch at 10:01 a.m. from the historic Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Cape Canaveral, Florida, the same launch pad used for the Apollo and space shuttle missions.

The SpaceX rocket will carry cargo for an International Space Station (ISS) resupply mission.

This is SpaceX's second planned launch this year. The company successfully launched a handful of satellites for Iridium Communications from California's Vandenberg Air Force Base in January, following a few postponements. That was SpaceX's first launch since a Falcon 9 rocket exploded on another Cape Canaveral launchpad during fueling in early September.
