Genesis Solar Observation Spacecraft USA: related news

Genesis Solar Observation Spacecraft - , USA

The Genesis mission, which will be the first to return a space sample to Earth since Apollo 17, is expected to bring back particles from solar winds in space generated by the Sun. Solar wind is one small variable in the growing field of space weather, which mainly focuses on solar flares.

Hessi Solar Flare Observation Spacecraft - , USA

The High Energy Solar Spectroscopic Imager (HESSI) spacecraft was launched in February, 2002. The spacecraft was designed to explore the basic physics of particle acceleration and explosive energy release in solar flares. HESSI is designed to image solar flares in energetic photons from soft X-rays.

Low-Impact Mating System for Docking Spacecraft

A document describes a low-impact mating system suitable for both docking (mating of two free-flying spacecraft) and berthing (in which a robot arm in one spacecraft positions an object for mating with either spacecraft). The low-impact mating system is fully androgynous: it mates with a copy of itself, i.e., all spacecraft and other objects to be mated are to be equipped with identical copies of the system. This aspect of the design helps to minimize the number of unique parts and to standardize and facilitate mating operations. The system includes a closed-loop feedback control subsystem that actively accommodates misalignments between mating spacecraft, thereby attenuating spacecraft dynamics and mitigating the need for precise advance positioning of the spacecraft.

'Impressionist' Spacecraft to View Solar System's Invisible Frontier

(PhysOrg.com) -- At the edge of our solar system in December 2004, the Voyager 1 spacecraft encountered something never before experienced during its then 26-year cruise through the solar system — an invisible shock formed as the solar wind piles up against the gas in interstellar space. This boundary, called the termination shock, marks the beginning of our solar system's final frontier, a vast expanse of turbulent gas and twisting magnetic fields.

First Solar (FSLR): Encourage profit taking/shorting here - FBR

FBR is out with a negative call on First Solar (NASDAQ: FSLR) and SunPower (NASDAQ: SPWR) after Solar Electric Power Association (SEPA), an industry association bridging the solar and utility industries, announced yesterday theresults of its survey of utility companies (titled:"Utility Solar Electricity Market Survey"). Summary: (a) projected PV installations of ~2 GW, on aggregate, over the next three to five years in solar portfolio, versus >3 GW for CSPs across the U.S. utilities; (b) possible paradigm shift, with utilities owning the plants and PV suppliers becoming only turn-key provider (if ITC is given to utilities instead of third parties).

IBEX Spacecraft Heads West, Takes Major Step Toward Launch

GREENBELT, Md., July 25 /PRNewswire-USNewswire/ -- NASA's Interstellar Boundary Explorer (IBEX) spacecraft, designed to image global interactions at the outer reaches of the solar system, today began its move to Vandenberg Air Force Base (VAFB), Calif. The IBEX spacecraft was loaded into a truck at Orbital Sciences Corporation, Va., where engineers integrated the science payload with the spacecraft and completed numerous tests to ensure optimum performance during the launch and operational phases of the mission. "This is a huge milestone for the IBEX mission. It's great to have our spacecraft making its road trip west," said Dr. David McComas, IBEX principal investigator and senior executive director of the Space Science and Engineering Division at Southwest Research Institute.

Our Solar System: An Island of Calm in a Violent Universe (and it's special, too)

We humans like to think we're special, but astronomically speaking we've been shot down quite severely and humbly put in our place. We're not at the center of our solar system, nowhere near the center of our galaxy and certainly not at the center of the universe. But now comes great news for the human psyche from scientists trying to explain solar system formation. As far as solar systems go, we have thought ours was just average and that all solar systems were like ours. But in looking at the 300 plus extrasolar planets that have been discovered and the systems they are in, none so far are anything like our home solar system. In fact, say scientists at Northwestern University, we may be special after all. In a study using computer simulations (this is the week for computer simulations, see here and here), researchers ran more than a hund

Researchers Improve Solar Cell Performance

Vegematic writes "Researchers at MIT have improved solar collectors using dyes. They just increased their performance results by a factor of 4. These paint-on materials can increase the power obtained from existing solar cells by a factor of over 40 without needing to track the sun. 'By collecting light over their full surface and concentrating it at their edges, these devices reduce the required area of solar cells and consequently, the cost of solar power. Stacking multiple concentrators allows the optimization of solar cells at each wavelength, increasing the overall power output.' There is also a shorter FAQ available."

First Images of Solar System's Invisible Frontier

FiReaNGeL writes an unexpected side-effect from NASA's STEREO spacecraft has allowed scientists to see a much more well defined picture of the boundary of our solar system. "The twin STEREO spacecraft were launched in 2006 into Earth's orbit about the sun to obtain stereo pictures of the sun's surface and to measure magnetic fields and ion fluxes associated with solar explosions. Between June and October 2007, however, the suprathermal electron sensor in the IMPACT (In-situ Measurements of Particles and CME Transients) suite of instruments on board each STEREO spacecraft detected neutral atoms originating from the same spot in the sky: the shock front and the heliosheath beyond, where the sun plunges through the interstellar medium."

The Yin and Yang of the NeXT Spacecraft

Hard and soft. Dark and bright. High and low. Wide and thin. JAXA and NASA. And that's just one spacecraft. Japan's space agency, JAXA and NASA are teaming up to create a new spacecraft to study the extreme environments of the universe. NeXT, which stands for New exploration X-Ray Telescope is a next generation x-ray astronomy satellite currently under development, with launch scheduled in 2013. While Japan will provide the main spacecraft and several instruments, NASA, and in particular the Goddard Space Flight Center just announced they will be adding a new instrument to the spacecraft, the High-Resolution Soft X-Ray Spectrometer (SXS). While the spacecraft's main instrument will be its Hard X-ray Telescope (HXTs) the addition of SXS is just one of several complementary instruments that provide a "yin and yang" aspect to NeXT's explorat

LDK Solar gets 440 MW solar wafer contract

Chinese solar product maker LDK Solar Co. Ltd. said Friday it will supply about 440 megawatts of solar wafers to South Korea's Hyundai Heavy Industries Co. Ltd., the world's largest shipbuilder.

NASA Set For Solar Sail Test

Solar sails have featured in various sci-fi mediums for a good while now, but NASA are planning to make the technology a reality in a mission which could launch as early as the 29th of July. An earlier 2005 launch of a solar sail craft by The Planetary Society was deemed unsuccessful, so if NASA's experiment fairs better it could be the first step to enabling space exploration powered by the sun's energy. The solar sail, dubbed the NanoSail-D is made up of aluminium and space age plastic and measures 100 square feet when unfurled. A sail of that size isn't enough to carry a craft of any significant size, but sails of thousands of square feet could open up some interesting possibilities. In theory, solar sails would be a better choice than conventional rockets for longer missions.

LDK Solar Awards $220M Contract to Applied Materials for Precision Wafering Systems to Support Production Expansion

LDK Solar Co., Ltd, a leading manufacturer of solar wafers, awarded a US$220 million contract to Applied Materials, Inc. to provide precision wafering systems to support its next phase of production expansion. The systems are scheduled to begin shipping to LDK Solar's facility in Xinyu, PRC, in early 2009, and will support LDK Solar's previously announced plans to expand to 3.2GW annualized wafer capacity in 2010.

Solar Power Hits Home

There were limits to how green Bruce Letvin was willing to go. For years, the 53-year-old anatomy professor had wanted to install solar panels on his Manhattan Beach, Calif., home. But the up-front installation costs always outweighed the benefits for the environment and his conscience. This spring, however, he managed to work out green financing with the help of solar company SunPower. After determining that his electricity bills and roof exposure were large enough to make him a good candidate for its solar panels, the company, based in San Jose, Calif., helped him find a 15-year loan for the $64,500 system. Yes, his $550 loan payment is more than the $300 or so he used to spend each month on electricity bills--so far, he has generated enough solar power that he doesn't need to take any juice from the grid--but after he pays off the loan

World's Largest Solar Plants Planned In California

Pickens writes "Two photovoltaic solar power plants will be built in San Luis Obispo County in California, covering 12.5 square miles, that together will generate about 800 megawatts of power, the latest indication that solar energy is starting to achieve significant scale. 'If you're going to make a difference, you've got to do it big,' said Randy Goldstein, the chief executive of OptiSolar. OptiSolar will employ enough of its amorphous silicon thin-film solar panels at its Topaz Solar Farm project to generate 550 MW. Meanwhile, SunPower will install mechanical tracking for its more expensive 250 MW-worth of crystalline silicon photovoltaics at High Plains Ranch II in a bid to boost their efficiency by 30 percent from following the sun across the sky.
