Mining the moon for water and nuclear fuel
Mining the moon for water and fuel.
Texas-based Shackleton Energy Company has already begun operations aimed at mining the Moon within the next few years.
The company’s plans for mining and refining operations would involve melting the ice and purifying the water, converting the water into gaseous hydrogen and oxygen, and then condensing the gases into liquid hydrogen, liquid oxygen and hydrogen peroxide, all potential rocket fuels.
Shackleton CEO Dale Tietz says the water extracted would be used almost exclusively as rocket fuel to power operations both within Low Earth Orbit (LEO) – such as space tourism and the removal of space-debris – on the Moon, and further out into space. ‘We are a for-profit business enterprise moving forward, and so we are only going there really for one reason and that is to mine, prospect mine and harvest water for rocket propellant production,’ says Tietz.

Dawn’s approach to Vesta continues
Dawn’s approach to Vesta continues.
Starting at the beginning of the approach phase on May 3, Dawn interrupted thrusting once a week to photograph Vesta against the background stars. These images help navigators determine exactly where the probe is relative to its target. This technique does not replace other means of navigation but rather supplements them. One of the principal methods of establishing the spacecraft’s trajectory relies on accurately timing how long it takes radio signals, traveling, as all readers know, at the universal limit of the speed of light, to make the round trip between Earth and Dawn. Another uses the Doppler shift of the radio waves, or the slight change in pitch caused by the craft’s motion. These sensitive measurements remain essential to navigating the faraway ship as it sails the interplanetary seas.
Despite the very slow approach, the distance is small enough now that observing Vesta weekly is no longer sufficient. To achieve the navigational accuracy required to reach the intended orbit in early August, last week the frequency of imaging was increased to twice per week. In each session, half of the pictures are taken with long exposures to ensure many stars are detectable, thus overexposing the much brighter disc of the nearby Vesta. The other half use short exposures to ensure that the rocky world shows up correctly so its precise location can be measured. The visible and infrared mapping spectrometer has been commanded to observe Vesta during three of these sessions, each time providing valuable information that will help scientists select instrument settings for when Dawn is close enough to begin its detailed scientific measurements.

NASA Foresees 2-Year Final Shuttle Retirement Phase
Seems a bit long to me: NASA foresees a two year period after the last shuttle lands to retire the program completely.

Cassini looks past one Saturn moon to another
The image below was taken on January 11, 2011 by the space probe Cassini, in orbit around Saturn. First we see the southern polar regions of the moon Rhea, 949 miles in diameter. Beyond is the moon Dione, 698 miles across, appearing to sit on the rings of Saturn.
As far as I am concerned, this image, as well as almost every other image from Cassini, proves that any hotel built in orbit around Saturn is unquestionably going to be one of the hottest tourist spots in the solar system.

ATV burns up, Progress launched
Busy day for travel to and from ISS: The European unmanned ATV freighter Johannes Kepler burned up in the atmosphere even as a Russian Progress freighter was launched.
In related news, the U.S. and ESA are in negotiations to merge the European unmanned ATV freighter program with NASA’s manned Orion derivative. At the same time, Europe has announced its plans to test fly a reusable space plane.

NASA about to decide on its shuttle heavy-lift replacement
NASA is about to decide on its shuttle heavy-lift replacement, and it looks like it will be almost entirely shuttle-derived.
As I have said previously, this rocket will almost certainly never fly. NASA has to start over after spending billions and years developing Constellation, and is being given less money and time to do it.
And even if I am wrong and this rocket does fly, I bet it will do only one flight and then be retired as too costly.
