Station Spacewalkers Install Experiments

Station Spacewalkers Install Experiments, Probe

The Exposing Specimens of Organic and Biological Materials to Open Space (Expose-R) experiment was installed on the universal science platform mounted to the exterior of the Zvezda Service Module.

The spacewalkers also removed straps, or tape, from the area of the docking target on the Pirs airlock and docking compartment. The tape was removed to ensure it does not get in the way during the arrival of visiting Soyuz or Progress spacecraft. Fincke and Lonchakov later took photos of the exterior of the Russian portion of the station to document its condition after a decade of operation in the harsh environment of space. The photos will be used to assess the condition of the outer surfaces and structural elements of the station, including active components such as thrusters and vents.

Kepler Launch

Astronomy & Space Headlines - Kepler Launch, Next Shuttle Launch, Costs Increase

The Kepler spacecraft and its Delta II rocket have been cleared to launch into space late Friday night following a thorough review by launch managers Monday.

Liftoff is scheduled for 10:49 p.m. EST. The Launch Services Program was joined by officials and engineers from the United Launch Alliance, the Kepler program and others to examine all aspects of the observatory and the launcher.

Kepler is a spaceborne telescope designed to search the nearby region of our galaxy for Earth-size planets orbiting in the habitable zone of stars like our sun. The habitable zone is the region around a star where temperatures permit water to be liquid on a planet's surface.

Basic Astronomy News

Easier - Astronomy is the study of things found in space such as the sun, planets, moons, and stars.

Advanced -Astronomy , one of the oldest sciences, is the study of celestial bodies such as planets, stars, and other objects in space. Astronomers locate objects in the daytime or nighttime skies and measure their magnitudes and motions, searching to find what they are made of and how they create their light.

An astronomer is a scientist who studies celestial bodies such as planets, stars, and galaxies. Historically, astronomy was more concerned with the classification and description of phenomena in the sky, while astrophysics attempted to explain these phenomena and the differences between them using physical laws. Today, that distinction has mostly disappeared. Professional astronomers are highly educated individuals who typically have a PhD in physics or astronomy and are employed by research institutions or universities. They spend the majority of their time working on research, although they quite often have other duties such as teaching, building instruments, or aiding in the operation of an observatory.

Solar astronomy : Main article: Sun At a distance of about eight light-minutes, the most frequently studied star is the Sun, a typical main-sequence dwarf star of stellar class G2 V, and about 4.6 Gyr in age. The Sun is not considered a variable star, but it does undergo periodic changes in activity known as the sunspot cycle. This is an 11-year fluctuation in sunspot numbers. Sunspots are regions of lower-than- average temperatures that are associated with intense magnetic activity. Astronomy brief news.
