According to this article, the water-ice discovered at Shackleton Crater is insufficient for human settlement.
The uncertainty of science: According to this article, the water-ice discovery announced yesterday at Shackleton Crater is insufficient for human settlement.
The latest LRO data indicate “that water is not there … in a way that would facilitate human exploration,” says planetary scientist Maria Zuber, who led the team analyzing the data.
If the signatures the team saw in the soils on the crater floor do indicate water, how much water might there be? Roughly 100 gallons – enough to fill two or three residential rain barrels – spread over a surface of about 133 square miles. Leave the swim-suit at home. “This is not like Mars,” says Dr. Zuber, a professor at the Massachusetts Institute of Technology in Cambridge, in an interview. On the red planet, explorers would find thick layers of icy soil in many locations just by turning over a shovelful or two of topsoil. [emphasis mine]
This story seems to answer my question about Zuber’s participation in the water in Shackleton paper as well as the previous paper saying there is much less water on the Moon than previously believed. It also raises questions about the journalism work of many of the other stories published in the past few days, which heavily touted the possibility of water in Shackleton.
I intend to dig into this story a bit more. Stay tuned.

Excalibur Almaz has signed a deal to use Xcor’s Lynx suborbital craft to train its astronauts.
The competition heats up: Excalibur Almaz has signed a deal to use Xcor’s Lynx suborbital craft to train its astronauts.
Since Xcor has not yet flown Lynx, and Excalibur Almaz as a lot of work to do to make its Soviet-era modules flyable, I would bet that this news release is mostly public relations hype, centered as much on raising investment funds for both companies as it is about training astronauts.

This was the second flight of WhiteKnightTwo in three days, and is in line with Virgin Galactic’s test flight schedule announced in May. If the test flights go well, expect that first rocket-powered flight of SpaceShipTwo later this year.

A new company has announced plans to use the Gemini capsule design from the 1960s to provide crew and cargo capability to orbit.
The competition heats up: A new company has announced plans to use the Gemini capsule design from the 1960s to provide crew and cargo capability to orbit.
“Since this is an existing and proven design we could begin construction six to eight weeks after funding and complete a flying prototype ten to thirteen months later,” said WestWind President Bill Jolly.

Engineers have successfully tested a spare reaction wheel on Mars Odyssey in their effort to bring the spacecraft back into full operation.
Engineers have successfully tested a spare reaction wheel on Mars Odyssey in their effort to bring the spacecraft back into full operation.
After more than 11 years of non-operational storage, the spare reaction wheel passed preliminary tests on Wednesday, June 12, spinning at up to 5,000 rotations per minute forward and backward. Odyssey engineers plan to substitute it for a reaction wheel they have assessed as no longer reliable. That wheel stuck for a few minutes last week, causing Odyssey to put itself into safe mode on June 8, Universal Time (June 7, Pacific Time).

If this space probe goes down, it will make it more difficult to rely data back from Opportunity, now on the Martian surface, and Curiosity, due to land in two months.

Congressman Frank Wolf (R-Virginia) has backed down and modified the language he had inserted in the NASA budget bill that would have limited the number of commercial space companies NASA could subsidize.
Good news: Congressman Frank Wolf (R-Virginia) has backed down and modified the language he had inserted in the NASA budget bill that would have limited the number of commercial space companies NASA could subsidize.
From Clark Lindsey:
Rep. Frank Wolf (R-VA) , who is Chairman on the Commerce-Justice-Science subcommittee of the House Appropriations committee, put language into the recent House budget for NASA that requiree NASA to down-select immediately to one primary contractor in the commercial crew program. This would obviously eliminate competition on price and rule out redundancy in case one system is grounded. He has now relented and is willing to allow for “2.5 (two full and one partial) CCiCAP awards”.
As I wrote earlier, the success of Dragon is putting strong political pressure on Congress to support the independent commercial space companies over the NASA-built and very expensive Space Launch System (SLS) that Congress had mandated. Expect to see more elected officials back down in the coming year, with the eventually elimination of SLS from the budget.
