In mid-July, the media reported on the dispute over the sculpture "Fallen Astronaut", left on the Moon by Scott in tribute to those killed in the American and Soviet space programs; the sculptor was having copies made for public sale, over the astronauts' objection. Due to the increasing publicity surrounding the incident, and concerned about the appearance of commercialization of Apollo 15, the Senate Committee on Aeronautical and Space Sciences set a hearing for August 3. It called a number of NASA employees including the astronauts, Slayton, Kraft, Fletcher and Low to appear. Fletcher and Low had tried to talk Senator Anderson out of having a hearing, but the chairman insisted. Worden remembered that while there were difficult questions asked about the astronauts' conduct, part of the committee's concern was why NASA management had allowed another incident to happen so quickly after the Apollo 14 Franklin Mint matter. Members also wanted to know how it was that NASA's chain of command permitted allegations against the astronauts to go unreported to senior management. Because of the efforts of Fletcher and Low, Anderson invoked a rarely used Senate rule for when testimony might impact the reputation of witnesses or others, closing the hearing to the public. Kraft recalled that while he and Low were grilled by the committee, the senators treated the astronauts "like gods".
