The sun lightens our world and enlightens our scientists as they look to our closest star for a better understanding of solar activity and what it means for our planet. Unique data from solar studies help researchers build on their knowledge of the Earth's atmosphere and climate change. June 30 marked the second time the International Space Station literally went out of its way to accommodate this research by providing a better viewing opportunity to meet Solar facility science objectives.

"The European scientists requested that we reposition the station slightly because by having this period of time they could bridge over the two Solar observing visibility windows, allowing them to view the sun for a full solar rotation without interruption," said International Space Station Program Scientist Julie Robinson, Ph.D. "The International Space Station Program took a look at the request and was able to change the station's position to increase science return."

The first station adjustment took place between Dec. 1 and 11, 2012, when the attitude of the orbiting laboratory was temporarily altered by about 7.5 degrees to provide a longer viewing time of the sun for the European Space Agency's (ESA) Solar observatory on the External Payload Facility of the Columbus module. This summer adjustment to the space station's position offers an additional opportunity to follow an entire solar rotation, approximately 27 days as determined by viewing sunspots from Earth.

"A very important contribution from the Solar 'bridging' measurements is the possibility it brings to perform inter-comparisons over an entire period of a Solar rotation with data from other solar instruments in orbit (e.g. a comparison of ESA's Solar-SOLACES data and NASA's SDO/EVE data)," said ESA Solar Project Scientist Astrid Orr, Ph.D. "The December bridging already shows that these particular data sets agree extremely well with each other."

The measurements for this Solar window observation are planned to run from June 18 to July 23, with the bridging event beginning on July 1. Normally viewing from the station only allows for short visibility windows of 10 to 12 days at a frequency of about once a month. After that timeframe, the observation window is blocked by the structure of the station itself, such as the solar arrays. Changing the position of the station increases the visibility of the sun, enabling scientists to view a full rotation from the orbital vantage point.

The Solar observatory launched to the station in February 2008 and currently houses two active investigations: Solar-SOLACES and Solar-SOLSPEC. Solar-SOLACES, which stands for Solar Auto-Calibrating Extreme UV/UV Spectrophotometers, collects data between 15 and 220 nanometers (nm) for extreme-ultraviolet/ultraviolet solar spectral irradiance. Solar-SOLSPEC, which stands for Solar Spectral Irradiance Measurements, measures between 180 to 3,000 nm for absolute solar spectral irradiance. Solar irradiance measurements tell scientists how much energy reaches Earth's atmosphere from the sun during any given period of time.

The goal of these studies is to gain accurate solar spectral irradiance measurements to understand variations in our environment due to solar radiation. With solar activity increasing, the timing of this adjustment will accommodate the investigations for improved science returns. These data can contribute to improved modeling of sunspots and other solar phenomena. The information also contributes to atmospheric and climatic models, helping researchers to predict sun and space weather activities.

"The bridging makes it possible for the scientists to develop a method for 'melting' both sets of data into one reference set of data in absolute physical values for the science community, which includes both solar physicists and climate researchers," said Orr.

Crew members aboard the International Space Station (ISS) had to add a little more distance between the orbiting laboratory and Earth on Sunday for a science experiment.

NASA said astronauts raised the space stations altitude to accommodate a research project aimed at learning about Earths atmosphere and climate change.

The European scientists requested that we reposition the station slightly because by having this period of time they could bridge over the two Solar observing visibility windows, allowing them to view the sun for a full solar rotation without interruption, said International Space Station Program Scientist Julie Robinson, PhD. The International Space Station Program took a look at the request and was able to change the stations position to increase science return.

This adjustment offers an additional opportunity to follow an entire solar rotation, about 27 days as determined by viewing sunspots from Earth.

A very important contribution from the Solar bridging measurements is the possibility it brings to perform inter-comparisons over an entire period of a Solar rotation with data from other solar instruments in orbit (e.g. a comparison of ESAs Solar-SOLACES data and NASAs SDO/EVE data), said ESA Solar Project Scientist Astrid Orr, PhD. The December bridging already shows that these particular data sets agree extremely well with each other.

NASA said measurements for this Solar window run from June 18 to July 23. Normally viewing from the station only allows for short visibility windows of 10 to 12 days at a frequency of about once a month. After this, the observation window is blocked by the structure of the station. Changing the position of the station increases the visibility of the sun and enables scientists to view a full rotation from the orbital vantage point.

The bridging makes it possible for the scientists to develop a method for melting both sets of data into one reference set of data in absolute physical values for the science community, which includes both solar physicists and climate researchers, said Orr.

The stations orbit is turned so it is mostly sunlit, giving instruments optimal opportunity for measurements. This meets the solar science teams requirements to observe the sun through a full solar rotation. After observations are complete the station will return to its standard altitude, but investigators will continue to collect data.

An astronaut aboard the International Space Station has become the first person ever to control a robot on earth from space.

Flight engineer Chris Cassidy remotely controlled the K10 rover based in California from space to simulate deploying a radio telescope.

The mini mission was designed to test how well a crew member in space can remotely control a robot, whether it is on the surface of a moon, planet or asteroid.

Cassidy took the rover, based at the Ames Research Centre in California, on a remote test drive before using it to deploy the simulated antenna.

The hiss of air escaping from a leaky car tire is no one's favorite sound. Even less pleasant? Hearing that hiss of escaping air 250 miles above Earth's surface while inside the pressurized confines of the International Space Station.

According to Eric Madaras, an aerospace technologist at NASA's Langley Research Center in Hampton, Va., if an air leak were to occur aboard the station, alarms would sound, and the astronauts would locate and correct the problem according to procedures. But with only the crew's eyes and ears to go on, pinpointing the source of a leak could be tricky.

Madaras is trying to fix that problem. As the principal investigator for the Ultrasonic Background Noise Test (UBNT) he's leading a study that potentially could help prevent a catastrophic loss of air pressure on a crewed spacecraft.

By observing the high-frequency noise levels generated by hardware and equipment operating in the Destiny laboratory and Tranquility module aboard the space station, Madaras and his team are helping to develop an automated system that would locate air leaks in a space structure's pressure wall - the outside part of the orbiting laboratory that keeps in oxygen.

"If a leak does occur, it's one of those things where you may not have a lot of time," Madaras said. "These guys can always go sit in the Soyuz capsule and close the door and go home. They've got that capability. But no one wants to just abandon ship, so there's always this desire to deal with it."

But dealing with a leak means identifying the source. Right now, that would require someone to listen for the signature hiss of escaping air - not an easy or quick task, especially on a noisy space station that has structures covering the wall where the leak might originate.

That's why, as part of UBNT, astronauts are in the process of installing several distributed impact detection system (DIDS) units on the pressure walls of the space station. DIDS units are high-speed, four-channel digitizers that record ultrasonic noises. Instead of listening for the hiss of air, these units detect the high-frequency sounds moving through the metal itself. Each unit has four pressure-sensitive transducers, which Madaras compares to the pickup coils on an electric guitar.

"That's where the rubber meets the road," Madaras said. "[The transducer] would essentially be stuck on the surface and anything that moves the surface up or down would be picked up."

Fourteen DIDS units will be installed aboard the space station: seven in Destiny and seven in Tranquility.
