A Return to the Moon by the Apollo 11 50th Anniversary.

A manned lunar landing flight for less than $100 million in launch cost, assuming the Falcon Heavy really does hit the $1,000 per pound price point:

Notably it uses European stages for the translunar injection and lander stages. Then you could have an all European mission if using an Ariane 5 ME and a separate human-rated European launcher for crew instead of a Falcon Heavy.
As I discussed before, a European human-rated launcher is doable by just selecting for the Ariane 6 the all-liquid fueled version. This could also be ready by the same 2017-2018 time frame for the Ariane 5 ME.
This is another advantage of the liquid-fueled version of the Ariane 6. It could also allow low cost European manned lunar flights around the same time as the Americans.

NASA Plans to Make Water on the Moon.

This mission builds on the LCROSS mission. I consider LCROSS to be
one of the most successful planetary missions ever developed since it
returned such profoundly important results at such low cost. The cost/
benefit ratio was tremendous. (As a mathematician I suppose I should
express that as the benefit/cost ratio was tremendous. ) I hope NASA
selects the same award-winning managers as for the LCROSS mission.

I do have a question about the mission. The article describes it will
have a limited lifetime because of the limited sunlight at the
location it will visit. But I recall there were locations close to
some shadowed craters that were nearly continually bathed in sunlight.
Could these locations be used to get a longer mission?

Discussion of a low cost European crew capsule:

Budget Moon flights: lightweight crew capsule.

According to NASA administrator Charles Bolden, NASA will not be
returning us to the Moon(*) but may engage in partnerships with other
space agencies or private entities who could.
Then it's interesting the ESA has the required lightweight in-space
stages and lightweight capsule in the Cygnus to accomplish this at low
cost.
Another key fact is that NASA has shown with SpaceX and now with
Orbital Sciences that development costs can be cut drastically (by 80
to 90% !) by following a commercial approach.
Then this could be a project NASA could encourage, at low cost to
NASA, by partnering with ESA and private entities like Golden Spike,
while at the same time satisfying the critics who want us to return to
the Moon.
