NASA Administrator Jim Bridenstine said in an interview today that his decision to reassign Bill Gerstenmaier and Bill Hill was not abrupt, but reflected a growing concern that cost and schedule estimates for the systems needed for the Artemis program are unrealistic.

The Senate Commerce, Science, and Transportation Committee today (July 10, 2019) approved a bill to protect lunar heritage sites — such as where Apollo 11 landed — as more countries and companies pursue activities on the Moon’s surface. The bill requires anyone getting a license from the U.S. government to conduct lunar activities to agree to observe recommendations developed by NASA in 2011 and any updates to it.  Sen. Ted Cruz (R-TX), a co-sponsor of the bill, said he would work with the House to pass the legislation and get it on the President’s desk “quickly.” [UPDATE: An amended version of the bill passed the Senate on July 18.]
