What we need to do is get the Triana/DSCOVR mission launched and in place at the L1 point. This mission is designed to monitor the radiation budget for the Sun and Earth and to give some very important information about global climate change. The Bush administration deep sixed the mission for years for no really valid reason as far as I can tell. NASA just tested the spacecraft (it was built years ago and has been sitting in a warehouse waiting for Bush to go away) and it is in good health. The Bush administration had not been willing to publicly announce why they blocked its launch. They also refused to release documents about administrative reviews of the mission. Secrecy is such an aggravating policy and it results in a lot of guess work by others.
A few hundred million dollars to launch this craft would tell us a lot about global climate change. Unfortunately, nearly 8 years of data have been missed because the already completed craft is just sitting idle in a warehouse.
