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.

US, Russian Satellites Collide Over Siberia

US, Russian Satellites Collide Over Siberia

Washington (AFP) Feb 11, 2009

US, Russian Satellites Collide Over Siberia Two satellites collided in space hundreds of miles (kilometers) above Earth, destroying an Iridium commercial satellite in a crash that may result in disruption of service, the US company said Wednesday. The Bethesda, Maryland-based company said it "lost an operational satellite" after it was struck Tuesday by a spent Russian satellite, in what is being described as the first major collision ...

No Seats Available For This Flight (NASA)

Astronomy News

Nasa Says : No Seats Available For This Flight !

Don't let the desert fool you. It's not always hot. In fact, in California's Mojave Desert where NASA and contractor employees are processing space shuttle Endeavour, it's freezing. "It's 32 degrees out here," said Ken Tenbusch, Endeavour flow director. "Not easy when your teeth are chattering." One of the major differences in processing at NASA's Kennedy Space Center in Florida and NASA's Dryden Flight Research Center in California is location. Within hours of landing at Kennedy, Endeavour would have been towed into one of the center's orbiter processing facilities -- a place where technicians have all of the resources they need right at their fingertips. But at Dryden, Endeavour is processed outdoors at the Mate-Demate Device with limited resources. "Processing outdoors offers many challenges," Tenbusch said. "Over here, you are completely open to the environment. The wind comes right off of the mountains and if it rains, you're getting rained on." The way orbiters are processed is different, too. At Dryden, crews basically have to winterize the vehicle before it's bolted to a 747 jumbo jet called the Shuttle Carrier Aircraft. Technicians power the orbiter down, safe all the hypergolic propellants and fuel systems, drain the water systems and close the nose and landing gear doors. Then, they install a large cone on the tail of the orbiter, which helps smooth the airflow around it during the ferry flight. "In order to do that, you have to manipulate the engines and bring them together so the cone will fit over the top of them," said Randy Goodmon, Endeavour flow manager. To perform these turnaround operations, about 250 NASA and contractor employees are working around the clock. Meanwhile, there are several systems engineers at Kennedy who can't wait to get their hands on Endeavour. "You can explain and send pictures -- but it's clearly not the same as being next to the hardware," Tenbusch said. Tenbusch and Goodmon say Endeavour appears to be in good shape. They even commented on the window that was hit by a meteor while orbiting Earth. "The window is fine for the flight back to Kennedy," Goodmon said. "But it will be removed and replaced before Endeavour's next mission." Even with the challenges, Tenbusch says his turnaround team is doing a great job preparing Endeavour for its piggyback ride to Kennedy. And while many wonder if landing in California put Endeavour behind schedule for its next mission, targeted for May 2009, Tenbusch remains optimistic. "There are ways to make up lost time. The two most prominent are overtime and diverting resources from one orbiter processing facility to another," Tenbusch said. "I truly believe the team will be able to respond well and make up the lost time." Source : NASA This post is about :
