NASA has to be trolling with the latest cost estimate of its SLS launch tower

NASA's problems with the mobile launch tower that will support a larger version of its Space Launch System rocket are getting worse rather than better.

According to a new report from NASA's inspector general, the estimated cost of the tower, which is a little bit taller than the length of a US football field with its end zones, is now $2.7 billion. Such a cost is nearly twice the funding it took to build the largest structure in the world, the Burj Khalifa, which is seven times taller.

This is a remarkable explosion in costs as, only five years ago, NASA awarded a contract to the Bechtel engineering firm to build and deliver a second mobile launcher (ML-2) for $383 million, with a due date of March 2023. That deadline came and went with Bechtel barely beginning to cut metal.
