Sixteen days earlier, its twin Voyager 2 had departed from the same pad. Between them, they would visit all four giant planets, take the first detailed photographs of their moons, and eventually cross into interstellar space -- the farthest any human-made objects have ever traveled. The pad they left from has been rebuilt three times since, and it has never stopped sending extraordinary machines to extraordinary places. They call it Slick Forty-one.

The upgrade transformed the pad into NASA's premier deep-space launch site. The two Helios probes departed from LC-41 in 1974 and 1976, flying c...

The pad sat dormant for nearly a decade before Martin Marietta stripped the existing mobile service tower and umbilical tower down to their main structural components in 1986. This was not demolition but renovation -- a 'tear-out and refurbish' contract that prepared the ITL for ...

The Atlas V relied on Russian-built RD-180 engines for its first stage, a dependency that grew untenable after Russia's 2014 annexation of Crimea and the 2022 invasion of Ukraine. ULA developed Vulca...
