One Number, Two Budgets
The Senate and House have both agreed to increase NASA's budget to $17.9B, but they have very different ways of spending that money
Posted by Van Kane on 2014/06/17 01:03 CDT | 2 comments
The Senate and House have both agreed to increase NASA's budget to $17.9 billion, but they have very different ways of spending that money. The House bill would add additional funding to almost every category of the Planetary Science budget and would greatly strengthen NASA’s program of planetary exploration. The Senate bill would add substantial funds to the Mars program but pay for this by cuts to other portions of the planetary budget.

The value of a Guest Investigator program for Dawn

NASA selected 21 Participating Scientists to join the Dawn team in 2010, prior to Dawn's arrival at Vesta in 2011. Since that time, Dawn Participating Scientists have made enormous contributions to the mission, as they do for most other NASA missions. But the status of a Participating Scientist program for Dawn at Ceres has been in doubt.
A Reluctant Dance Towards Europa
or, Why A Credible Europa Mission is Likely to Cost ~$2B
Posted by Van Kane on 2014/05/14 12:42 CDT | 15 comments
For the last two years, NASA has been the shy partner refusing to get on the dance floor, and Congress has been the aggressive partner insisting on a dance now. Recently, NASA has said maybe on another night but only if it’s a cheap date. While NASA says no for now, Congress looks to be willing to slip the band a cool $100M – on top of $150M already paid – to keep the music playing, but (to keep the metaphor going) has not been willing to fully commit itself to paying the bigger bill to rent the dance hall. The dance, of course, is the continuing attempt by Congress to have NASA commit to a mission to explore Europa, and NASA’s attempts to delay a mission well into the 2020s.
