HOW NASA/JPL ALTERED HIGH TEMPERATURES FOR MSL
This page under construction (4/24/2014)
This article will trace how NASA/JPL and the Rover Environmental Monitoring Station (REMS) Team, have altered temperatures reported by the Curiosity Rover at Gale Crater in Mars since it landed on August 6, 2012. It will also link to the current temperatures claimed up until at least Sol 600 for the Curiosity. Figure 1 (from Space.Com) shows that the initial temperatures reported were surprising warm.
Figure 1 - Report in Space.com dated October 1, 2012 discussing the warm temperatures seen since Curiosity landed on August 6, 2012.
(Figure 2 is Figure 14B in our Basic Report). It shows some of the altered temperatures.
Table 1 shows how originally reported temperatures were radically reduced.
