There are two availability numbers: physical blocks and time machine backups excluded.
Um… Thanks for the answers, but Elizabeth Plaid's reply is how I feel about them.
More info that may or may not pertain to your answers:
I installed MaverX over Lion weeks ago. The free hard drive space has been around 40 GB for weeks, until today. Time Machine is on all the time.
I know Time Machine has all the stuff that is gone now. Can I find out what it has that the main drive is missing? Can I find out what a clone backup has that the main drive is missing?

I see Venus, I see space’s vast expanse.

NASA Releases Images of Earth by Distant Spacecraft
July 22, 2013
PASADENA, Calif. — Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space.
NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. MESSENGER, the first probe to orbit Mercury, took a black-and-white image from a distance of 61 million miles (98 million kilometers) as part of a campaign to search for natural satellites of the planet.
In the Cassini images Earth and the moon appear as mere dots — Earth a pale blue and the moon a stark white, visible between Saturn’s rings. It was the first time Cassini’s highest-resolution camera captured Earth and its moon as two distinct objects.
It also marked the first time people on Earth had advance notice their planet’s portrait was being taken from interplanetary distances. NASA invited the public to celebrate by finding Saturn in their part of the sky, waving at the ringed planet and sharing pictures over the Internet. More than 20,000 people around the world participated.
"We can’t see individual continents or people in this portrait of Earth, but this pale blue dot is a succinct summary of who we were on July 19," said Linda Spilker, Cassini project scientist, at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “Cassini’s picture reminds us how tiny our home planet is in the vastness of space, and also testifies to the ingenuity of the citizens of this tiny planet to send a robotic spacecraft so far away from home to study Saturn and take a look-back photo of Earth."
Pictures of Earth from the outer solar system are rare because from that distance, Earth appears very close to our sun. A camera’s sensitive detectors can be damaged by looking directly at the sun, just as a human being can damage his or her retina by doing the same. Cassini was able to take this image because the sun had temporarily moved behind Saturn from the spacecraft’s point of view and most of the light was blocked.
A wide-angle image of Earth will become part of a multi-image picture, or mosaic, of Saturn’s rings, which scientists are assembling. This image is not expected to be available for several weeks because of the time-consuming challenges involved in blending images taken in changing geometry and at vastly different light levels, with faint and extraordinarily bright targets side by side.
"It thrills me to no end that people all over the world took a break from their normal activities to go outside and celebrate the interplanetary salute between robot and maker that these images represent," said Carolyn Porco, Cassini imaging team lead at the Space Science Institute in Boulder, Colo. “The whole event underscores for me our ‘coming of age’ as planetary explorers."
In the MESSENGER image, Earth and the moon are less than a pixel, but appear very large because they are overexposed. Long exposures are required to capture as much light as possible from potentially dim objects. Consequently, bright objects in the field of view become saturated and appear artificially large.
"That images of our planet have been acquired on a single day from two distant solar system outposts reminds us of this nation’s stunning technical accomplishments in planetary exploration," said MESSENGER Principal Investigator Sean Solomon of Columbia University’s Lamont-Doherty Earth Observatory in Palisades, N.Y. “And because Mercury and Saturn are such different outcomes of planetary formation and evolution, these two images also highlight what is special about Earth. There’s no place like home."
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL designed, developed and assembled the Cassini orbiter and its two onboard cameras. The Johns Hopkins University Applied Physics Laboratory in Laurel, Md., designed and built MESSENGER, a spacecraft developed under NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Ala., manages the program for the agency’s Science Mission Directorate in Washington. JPL and APL manage their respective missions for NASA. The California Institute of Technology in Pasadena manages JPL for NASA.

Astronaut Karen Nyberg washes her hair in zero G aboard the International Space Station.
My attraction to brains and big hair have led me to a confession: I’m in lust with an astronaut.
If the Texas GOP has its way, one clinic where women can choose abortion will serve this whole area.
Nighttime Image of Texas Cities
One of the Expedition 36 crew members aboard the International Space Station, some 240 miles above Earth, used a 50mm lens to record this oblique nighttime image of a large part of the nation’s second largest state in area, including the four largest metropolitan areas in population. The extent of the metropolitan areas is easily visible at night due to city and highway lights.
The largest metro area, Dallas-Fort Worth, often referred to informally as the Metroplex, is the heavily cloud-covered area at the top center of the photo. Neighboring Oklahoma, on the north side of the Red River, less than 100 miles to the north of the Metroplex, appears to be experiencing thunderstorms. The Houston metropolitan area, including the coastal city of Galveston, is at lower right. To the east near the Texas border with Louisiana, the metropolitan area of Beaumont-Port Arthur appears as a smaller blotch of light, also hugging the coast of the Texas Gulf. Moving inland to the left side of the picture one can delineate the San Antonio metro area. The capital city of Austin can be seen to the northeast of San Antonio.

Pavlof Volcano From Station
Astronauts aboard the International Space Station (ISS) photographed this striking view of Pavlof Volcano on May 18, 2013. The oblique perspective from the ISS reveals the three dimensional structure of the ash plume, which is often obscured by the top-down view of most remote sensing satellites.
Situated in the Aleutian Arc about 625 miles (1,000 kilometers) southwest of Anchorage, Pavlof began erupting on May 13, 2013. The volcano jetted lava into the air and spewed an ash cloud 20,000 feet (6,000 meters) high. When photograph ISS036-E-2105 (top) was taken, the space station was about 475 miles south-southeast of the volcano (49.1° North latitude, 157.4° West longitude). The volcanic plume extended southeastward over the North Pacific Ocean.

LAGEOS I, 1976
The LAGEOS I, Laser Geodynamics Satellite, was launched on May 4, 1976 from Vandenberg Air Force Base, California. The two-foot diameter, 900-pound satellite orbited the Earth from pole to pole and measured the movements of the Earth’s surface relative to earthquakes, continental drift, and other geophysical phenomena.
The mirrored surface of the satellite precisely reflected laser beams from ground stations for accurate ranging measurements. Scientists at NASA’s Marshall Space Flight Center in Huntsville, Ala. came up with the idea for the satellite and built it at the Marshall Center.

Of course NASA launched Earth’s disco ball in 1976.
Of course they did.
Commander Chris Hadfield, a Canadian astronaut who has been living aboard the International Space Station since December, on Saturday tweeted another stunning photo of the Windy City from above.
Holy crap, it’s a beautiful night in Chicago!
