At a recent workshop on lunar return, a critical part of the discussion focused on the need for a statement of purpose – a value proposition for the Moon.

You Can’t Always Get What You Want (but if you try some time, you might find … you get what you need)
A plan for a human mission to a near Earth object (NEO; an asteroid), designed by engineers from Georgia Tech and the National Institute for Aerospace (GT/NIA), was recently posted online. Keying in on lowering program total costs, this architecture eliminates the need for a new heavy lift launch ...

A recent article about the role of global magnetic fields in the loss of planetary volatiles caught my attention. The article addresses planetary climate issues as they relate to Earth, Mars and Venus, but what struck me was this statement:
We don't have a direct record of the sun's history, but a...

A recently published science paper presented results of a re-analysis of seismic (moonquake) data sent to the Earth from a network emplaced by the Apollo astronauts 40 years ago. The scientists processing the old data found that the Moon may have more than a simple core – it may have a layered, pa...

Hubble has done it again, squinting deeper into the universe, and hence farther back in time, than ever before. What it sees is a little smudge of light that turned out to be the most distant galaxy ever detected, 13.2 billion light-years away. It's not seeable in visible light, only in infrared. T...
