How Has NASA Improved Solar Power?

Solar energy is an up-and-coming field, but did you know that it owes much of its growth to NASA? Discover how NASA’s research and development of solar power for space has trickled down to the Earthly realm.

Continued improvements to solar power are imperative to future space travel. As missions blaze farther and farther into deep space, sunlight wanes. A 1-meter square (3. 2-foot) solar panel that produces about 400 watts near Earth would have to be 2,000 times bigger to generate the same amount of power in Pluto’s neighborhood (source: NASA). Thankfully, there are other promising products in development. Another NASA partner, MSGI Technology Solutions, recently unveiled solar cells that incorporate tiny carbon pillars, called nanotubes, into the solar cell design. The nanotubes help reduce reflected light, using the pillars to snag photons that would bounce off of a traditional flat panel. Also, the nanotubes increase the surface area of the panel, giving the product more room to capture light and produce more energy. That’s not all. Solar panel makers also face problems associated with dust and dirt. A tiny dust deposit of 0. 1 ounce (2. 8 grams) of dust per square yard (0. 9 meters) can reduce solar panel efficiency by as much as 40 percent.

NASA’s New Tech Could Bring Power to People “In the Middle of Nowhere”

Aeronautics research, including the aerodynamics of air flow over turbines, is one of the signature areas of research for NASA Ames.

The Cellulosic Biofuels Team is centered on bioengineering techniques that may enhance the efficiency of digestion enzymes, investigating fat extraction and analyses, and rosettazymes research to enhance the cellulose-to-glucose-to-fuels process. They issued an announcement on This summer 31, 2009 describing their current research.

Researchers at NASA Ames are conducting cutting-edge research in the development of clean energy technologies for NASA mission needs in the Exploration Systems Mission Directorate and the Science Mission Directorate. Our renewable energy focus is on advancing biofuels, solar, and wind technologies that also help reduce our nation’s dependence on petroleum-based fuels. By advancing clean energy technologies, NASA Ames hopes to help our nation reduce its generation of greenhouse gases and create a sustainable future here on Earth.

Harnessing the Power of the Sun

Originating Technology/NASA Contribution.

Pathfinder was been successful by Helios, a remotely piloted flying wing aircraft also developed included in ERAST. It, too, was initially designed and made by AeroVironment rich in-efficiency solar panel arrays over the wing, in addition to navigation and emergency lights, improved avionics, and much more efficient propellers.

The Environmental Research Aircraft and Sensor Technology (ERAST) Alliance was created in 1994 and operated for 9 years as a NASA-sponsored coalition of 28 members from small companies, government, universities, and nonprofit organizations. ERAST’s goal was to foster development of remotely piloted aircraft technology for scientific, humanitarian, and commercial purposes. Some of the aircraft in the ERAST Alliance were intended to fly unmanned at high altitudes for days at a time, and flying for such durations required alternative sources of power that did not add weight. The most successful solution for this type of sustained flight is the lightest—solar energy. Photovoltaic cells convert sunlight directly into electricity. They are made of semi-conducting materials similar to those used in computer chips. When sunlight is absorbed, electrons are knocked loose from their atoms, allowing electricity to flow.

Coating Processes Boost Performance of Solar Cells

NASA currently has spacecraft orbiting Mercury (MESSENGER), imaging the asteroid Vesta (Dawn), roaming the red plains of Mars (the Opportunity rover), and providing a laboratory for humans to advance scientific research in space (the International Space Station, or ISS). The heart of the technology that powers those missions and many others can be held in the palm of your hand—the solar cell.

Glenn Research Center is a national leader in evolving PV technology. The Center’s Photovoltaic and Power Technologies Branch has conducted numerous experiments targeted at developing lighter, more effective solar panels which are less costly to fabricate. Initiatives such as the Forward Technology Solar Panel Experiments I and II—in which Solar cells produced by NASA and industry were mounted outdoors the ISS—have tested how various solar technologies perform within the harsh conditions of space. While NASA seeks to enhance solar panels for space applications, the outcomes are coming back to Earth to profit the solar power industry.

Shedding Light on Solar Power

In the late 1970s, ENTECH, Inc., of Keller, Texas, developed a solar power concentrator for terrestrial applications that was spun into a concentrator for space in the early 1980s. Nearly 25 years later, the company has gone back to its terrestrial roots with a new concentrator that is a direct spinoff from its space technology.

In journeying backwards and forwards between Earth and space, ENTECH created strong business relationships with assorted U.S. Government departments, including NASA, which expressed curiosity about the business’s expertise and knowledge of solar concentrators and solar power conversion. Particularly, the organization was building solar energy concentrators using Fresnel lenses that efficiently convert solar energy into electricity by concentrating sunlight onto pv cells, or solar panels, that are non-mechanical devices produced from plastic alloys. Sunlight consists of particles of solar power known as photons, so when these particles strike a photovoltaic cell, they might be reflected, pass through, or perhaps be absorbed. Only part of the absorbed photons provides energy to create electricity.

The Development of Solar Power SatellitesE. Glaser Peter, in Advances in Energy Systems and Technology, Volume 2, 1979X CONCLUSIONSThe potential of the SPS to meet future energy demands is being recognized (H. R. 10601, 1978), and plans for its development are being studied. The results of extensive SPS system studies have confirmed that there are no known technical barriers to the design, deployment, or operation of the SPS. Economic studies have shown that projected capital and electric power-generation costs are within a competitive range of the costs of future terrestrial power-generation methods. Risk analyses have provided an economic justification for proceeding with the initial phases of an SPS development program. Environmental impacts have not emerged as a major constraint on SPS operation. The SPS is one of the most promising power-generation options that could contribute to meeting global energy demands in the twenty-first century. Its successful implementation (together with terrestrial solar energy conversion methods) could lead to the elimination of energy-related concerns.

High-Efficiency Solar Cell

Innovators at NASA’s Glenn Research Center have developed a high-efficiency multi-junction solar cell that uses a thin interlayer of selenium as the bonding material between wafers. Selenium is a unique semiconductor in that its transparent to light at photon energies below the band gap (infrared), enabling light to pass from the multi-junction top cell to the silicon-based bottom cell. The innovation allows a multi-junction solar cell to be developed without the constraint of lattice matching, and with a low-cost, robust silicon wafer as the supporting bottom substrate and bottom cell. This approach enables a cell that is simultaneously lower in cost, more rugged, and more efficient than existing space-based photovoltaic cells. This high-efficiency solar technology takes advantage of inexpensive silicon wafers and provides a more robust design for next-generation solar cells in space. For terrestrial applications, it can provide unprecedented efficiencies for auxiliary power units in vehicles, solar roof tiles, power plants, and smart grid systems.

The Case for Solar Power From Space

From Ad Astra, Volume 16 Number 1, 2022 Space-based power is a potential multitrillion-dollar market. Can we make the launch systems investments to tap it? By Arthur P. Smith Energy policy is in the news again, with debates in Congress, statements from presidential andidates, consternation over U.S. dependence on the Middle East for oil, and (…)

Searching in the major cost areas again, for that wholesale utility market space solar energy is presently in regards to a factor of two too costly regarding price of materials and components, and a minimum of an issue of 10 around the launch cost side. Both cost barriers have realistic likelihood of being overcome within the next decade.

Use of energy, whether fuel for transportation, electrical energy running the Internet, or the destructive energy released in weapons, is central to our economy and security. It is with good reason that the technical term for energy use per unit time, “power,” suggests control in the human world as well. Three actions taken now — working to reserve radio spectrum for power transmission, focusing on reductions in costs for space launch, and investing in space solar power system research — hold the promise of opening up vast new sources of power within the next 10 to 15 years.

The 25% efficiency of current solar panels just isn’t enough.

ROSA Rolls Out

Holy GrailLike an increasing number of people here on Earth, astronauts aboard the International Space Station (ISS) rely on solar energy to meet their electricity needs. They use advanced solar arrays to gather this power, and while the system they currently use is adequate, NASA is eager to find new ways to improve its efficiency. Click to View Full Infographic“We’ve been trying to get more efficiencies through solar arrays. That’s really the ‘holy grail,’” NASA’s acting administrator Robert M. Lightfoot Jr. tells Futurism. “You see, solar arrays are not very efficient. ”Typically, solar panels can only convert the Sun’s rays to electricity with an efficiency of about 25 percent. However, all kinds of attempts to improve this figure are underway, ranging from Japanese firm Kaneko’s record-breaking efforts earlier this year to a more recent research project out of Washington D.C. that pushed the upper boundary to 44. 5 percent efficiency. ROSA Rolls OutNASA’s primary concern is advancing the capabilities of the ISS, as well as other off-world craft that need electricity while navigating space on exploratory missions.

Solar Panels and Space

How solar panels perfected for space exploration revolutionised our renewable energy supplies here on Earth.

Following this tragedy, the Soyuz programme was delayed for 18 several weeks so the spacecraft might be redesigned and improved. Today, greater than half a century on from Soyuz 1, this spacecraft continues to be a workhorse from the space industry, ferrying astronauts back and forth from the Worldwide Space Station. Which is still operated by a ten. 6 metre solar array.

How do solar panels work?

This was only ten years after the first artificial satellite had been launched and six years after the first human in space. Space exploration was still very new and therefore Soyuz 1 encountered many technical difficulties. One of the solar panels did not unfurl properly causing a power shortage. After 13 orbits it was decided to return the mission to Earth. Sadly, the solar panel failure was not the only problem and on the return the parachute did not deploy properly, and the Soyuz crash landed, killing astronaut Vladimir Komarov.

NASA to upgrade space station solar arrays – NASA will start an upgrade this year of the solar arrays of the International Space Station to ensure it has sufficient power to last through the decade.

The arrays will be installed on top of six of the eight existing solar arrays on the station. Doing so allows the new arrays to use the tracking and power distribution systems of the existing arrays, minimizing the amount of new equipment needed. Each array will require two spacewalks to prepare the location where the arrays will be installed, and then to do the installation itself.

The International Space Station is about to get major power upgrade

The new solar arrays provide 20-30% more power for experiments and ongoing research in space.

KENNEDY SPACE CENTER, Fla. – Now the Worldwide Space Station will receive a group of upgraded solar arrays to power the station, supplying the juice required to keep your orbiting laboratory going throughout its lifecycle. The area station is really a full-time laboratory hosting countless experiments at the same time combined with the six or seven astronauts residing in the orbiting six-bed room home, and also to keep everything going takes lots of power. Presently, the ISS has eight solar arrays generating about 160 kilowatts of power total. It’s been greater than twenty years because the first solar arrays were placed on the ISS as well as with upgrades, solar panels degrade with time. The brand new Roll-Out Solar Arrays, or ROSA, tend to be smaller sized – but more effective with new technology – and can eventually provide 120 kilowatts, or 120,000 watts, of power throughout the daylight hrs. The very first two from six ROSAs will launch Thursday from Kennedy Space Center at 1:29 p. m. inside a SpaceX Cargo Dragon spacecraft because it delivers more then 7,200 pounds of supplies, hardware and experiments towards the ISS.

NASA awards UToledo grant to enhance solar power conversion for Mars, Moon missions

A team of engineers in The University of Toledo College of Engineering is working with NASA’s Jet Propulsion Laboratory to more reliably power spacecraft using the sun’s energy on future missions to Mars and the moon.

“We’re honored and excited our research will lead to NASA’s objective of putting more exploratory devices and electrical energy on Mars,” stated Khanna, that has done prior use NASA on power electronics and semiconductor studies. “Since I had been a child, it’s been an aspiration to utilize NASA and perhaps at some point walk around the moon like Neil Lance armstrong. “

“As the spacecraft is moving around and goes behind a celestial body, maximum available power tends to change rapidly,” Khanna said. “On the moon, lunar dust can also obscure the panel from the sun, leading to rapid changes in available power. Whether in deep space or in lunar missions, we need to develop a control algorithm to make sure we can always extract maximum available power from solar panels at a much greater efficiency while exhibiting improved radiation tolerance, allowing uninterrupted exploration.

Space Solar Power: An Extraterrestrial Energy Resource for the U.S

It’s been 20 years since the first astronauts took up residence on the International Space Station (ISS) and marked the beginning of a continuous human presence in space. Yet rather than kickstarting a new era of space megaprojects, the ISS remains the largest space infrastructure program ever undertaken. Insofar as it catalyzed a robust American commercial space industry, it is considered a resounding success. Launch costs have plummeted and commercial operators have gained the experience they need to take over key operational activities from NASA such as resupplying cargo and crew to the space station. The increased efficiency and lower costs have allowed NASA to once again set its sights on more ambitious deep space efforts, particularly sustained crew operations on the lunar surface and a crewed mission to Mars.

[FAQ]

How is solar energy being improved?

An alternative to making the solar cell itself move is to use mirrors to focus light on a smaller, and therefore cheaper solar cell. Another route to improving the performance of solar cells is to target their efficiency so they are better at converting energy in sunlight to electricity.

How does NASA use solar energy?

Energy from the Sun (solar power) These spacecraft have solar panels which convert the Sun's energy into electricity that powers the spacecraft. The electricity from the solar panels charges a battery in the spacecraft. These batteries can power the spacecraft even when it moves out of direct sunlight.

Did NASA develop solar energy?

Researchers at NASA didn't invent solar cells, but the organization did help keep the technology alive during the years when it was still largely uneconomical. Solar power has long been of interest at NASA, starting with Vanguard 1, the first artificial satellite powered by solar cells to start circling the globe.

How efficient are NASA solar panels?

Driven by weight and mostly size limitations, small spacecraft are using advanced power generation and storage technology such as >32% efficient solar cells and lithium-ion batteries.

Is solar technology improving?

Improvements and efficiency Now, solar panels ranging from 20 percent to 23 percent efficient are readily available to homeowners. In comparison to the heavy, hard-to-manage systems of the past, modern solar panels produced in the past five years are lighter and do not require as much rewiring or hardware to install.
