The space shuttle Endeavour and its crew are home after completing a 13-day mission. Endeavour's STS-118 mission successfully added another truss segment, a new gyroscope and external spare parts platform to the International Space Station. Endeavour's Commander Scott Kelly, Pilot Charlie Hobaugh and mission specialists Tracy Caldwell, Rick Mastracchio, Barbara R. Morgan, Alvin Drew and Canadian Space Agency astronaut Dave Williams landed at NASA's Kennedy Space Center in Florida on Tuesday at 12:32 p.m. EDT.

Williams, Mastracchio and station flight engineer Clayton Anderson, with the help of their crewmates, made four spacewalks to accomplish the construction tasks. The spacewalkers also completed work in preparation for upcoming assembly missions, such as relocating an equipment cart and installing support equipment and communication upgrades. During the mission, a new system that enables docked shuttles to draw electrical power from the station to extend visits to the outpost was activated successfully. Because the system worked, two additional days were added to Endeavour's mission.

Although managers addressed several issues with Endeavour's heat shield, including a small gouge in the protective tile on the orbiter's belly, inspections in orbit revealed no critical damage. Endeavour's thermal protection system was declared safe for re-entry on Monday. The orbiter will be processed immediately for its next flight, targeted for February 2008.

From the NASA Image of the Day site: Northern Arizona is best known for the Grand Canyon. Less widely known are the hundreds of geologically young volcanoes, at least one of which buried the homes of local residents. San Francisco Mountain, a truncated stratovolcano, was once a much taller structure before it exploded some 400,000 years ago a la Mt. St. Helens. The young cinder cone field to its east includes Sunset Crater, that erupted in 1064 and buried Native American homes. This ASTER perspective was created by draping ASTER image data over topographic data from the U.S. Geological Survey National Elevation Data.

PBS Arizona Stories: Apollo Astronaut Training

Wednesday, July 11, 2007

PBS is airing Arizona Stories: Apollo Astronaut Training Sunday, July 15, 2007. This documentary presents an overview of the USGS Astrogeology Research Program's involvement in training the Apollo astronauts in field geology techniques to help them acheive the science objectives of the lunar landing missions. From the transcript: "Beginning about 1964, the U.S.G.S. took Astronauts on geologic field trips to places like the Grand Canyon and Meteor Crater southeast of Flagstaff . When astronauts were not available, geologists dressed up in spacesuits and simulated the work that would be done on the moon. Learning to relay geologic observations by radio was important because during actual moon landings, U.S.G.S. scientists were at mission control, keeping track of where astronauts were on the lunar surface." The documentary includes interviews with Gene Shoemaker and Gerald Schaber, and video footage of training site preparation and activities.

Dust Storm Affects Mars Rovers

Friday, July 6, 2007

NASA - A giant dust storm brewing for more than a week on Mars has become worse and is affecting surface operations of the Mars Exploration Rovers, Spirit and Opportunity. Because the rovers depend on solar energy for survival, and the dust is partially blocking the sun, the storm is being watched closely by the rover scientists and engineers. Opportunity's entry into Victoria Crater is delayed for at least several days.

The storm, the most severe storm yet to hit the rovers, is expected to continue for at least another week. Opportunity is perched near "Duck Bay" as it readies to descend into Victoria Crater, but operations were scaled back on Saturday, June 30, to conserve power.

Tuesday, June 19, 2007

Mars Dunes database screenshot
Mars Digital Dune Database


The Mars Global Digital Dune Database presents data and describes the methodology used in creating the database. The database provides a comprehensive and quantitative view of the geographic distribution of moderate- to large-size dune fields from 65° north to 65° south latitude and encompasses approximately 550 dune fields.

The database is presented in a variety of formats. It is presented as a series of ArcReader projects which can be opened using the free ArcReader software. The latest version of ArcReader can be downloaded at the ESRI web site. The database is also presented in ArcMap projects. The ArcMap projects allow fuller use of the data, but require ESRI ArcMap software. Multiple projects were required to accommodate the large number of images needed. A fuller description of the projects can be found in the Dunes_ReadMe file and the ReadMe_GIS file in the Documentation folder. For users who prefer to create their own projects, the data is available in ESRI shapefile and geodatabase formats, as well as the open Geographic Markup Language (GML) format. A printable map of the dunes and craters in the database is available as a Portable Document Format (PDF) document. The map is also included as a JPEG file. ReadMe files are available in PDF and ASCII (.txt) files. Tables are available in both Excel (.xls) and ASCII formats.

Solar System Poetry

Tuesday, June 19, 2007

Stuart Atkinson, a U.K. writer and amateur astronomer, maintains a blog of his beautiful solar system poetry called The Verse. A snippet from his poem entitled "Titan":

The first time I saw you
I was twelve. Standing alone
In the crisp Christmas snow, eyes watering
With the cold I peered into my new
Telescope’s eyepiece and there you were:
A tiny – golden? – glint, a hint,
A spark of light beside
The badly-focussed globe of Saturn.

Looking at you even then I knew
That “moon” was far too shy a word.
Centuries of spying on you
Had revealed to Man the Truth,
That you were a World, a Planet
In all but name. Plaque-carrying Pioneers
And Voyagers had already sailed past you,
Cameras clicking in the cold
Of space, but your face remained
Hidden beneath that veil of ochre,
Choking cloud; our first emissaries found
No Mariner mountains poking through…

A U.S. Air Force C-17 cargo aircraft carried NASA's Phoenix Mars Lander spacecraft Monday, May 7, from Colorado to Florida, where Phoenix will start a much longer trip in August.

After launch, Phoenix will land on a Martian arctic plain next spring. It will use a robotic digging arm and other instruments to determine whether the soil environment just beneath the surface could have been a favorable habitat for microbial life. Studies from orbit suggest that within arm's reach of the surface, the soil holds frozen water.

Cassini searching for seas on Titan

Tuesday, May 8, 2007

Cassini to Confirm if 'Caspian Sea' is Liquid-Filled

For Cassini's next flyby of Titan on May 12, 2007, the radar instrument was originally pointing north of where it is now pointed. Due to the discovery of probable large seas on Titan, Cassini's quick-thinking team repointed the radar instrument south, so it could fly over a large, expansive dark area dubbed the "Caspian Sea." This flyby will confirm whether it is liquid-filled. This area on Titan's north pole stretches 1,000 kilometers (620 miles) and is only slightly smaller than Earth's Caspian Sea.

The presence of seas on Titan reinforces the idea that Titan's surface must be re-supplying methane to its atmosphere.

Cassini Spacecraft Images Seas on Saturn's Moon Titan

Wednesday, March 14, 2007

Instruments on NASA's Cassini spacecraft have found evidence for seas, likely filled with liquid methane or ethane, in the high northern latitudes of Saturn's moon Titan. One such feature is larger than any of the Great Lakes of North America and is about the same size as several seas on Earth.

Cassini's radar instrument imaged several very dark features near Titan's north pole. Much larger than similar features seen before on Titan, the largest dark feature measures at least 100,000 square kilometers (39,000 square miles). Since the radar has caught only a portion of each of these features, only their minimum size is known. Titan is the second largest moon in the solar system and is about 50 percent larger than Earth's moon.
