On UCLA’s main website there is a ‘space missions’ page. On it there is a section for the Diviner mission, which mapped the Moon’s surface temperature. We covered it in a series of posts a while back, as it is crucial to our understanding of Earth’s climate:
Diviner: The Diviner Lunar Radiometer is one of seven instruments aboard NASA’s Lunar Reconnaissance Orbiter spacecraft, which was launched on June 18, 2009. It is the first instrument to create detailed, global maps of surface temperature over the lunar day and year. Diviner’s measurements are also used to map compositional variations, derive subsurface temperatures, assess the stability of potential polar ice deposits, and infer landing hazards such as roughness and rock abundance.

But the links to the diviner subdomain are broken, and although references to other pages about the mission such as press releases and news articles are found by searching the UCLA site, the science has gone. OK, so websites get changed, links get broken, servers crash and don’t get rebooted for a while. So what? Why does this matter?
