#Satellite Solar Panels and Array

[aerospace-and-defence]

Exhaustive secondary research was done to collect information on the Satellite Solar Panels and Array Market, its adjacent markets, and its parent market. The next step was to validate these findings, assumptions, and sizing with industry experts across the value chain through primary research. Demand-side analyses were carried out to estimate the overall size of the market. Both, top-down and bottom-up approaches were employed to estimate the complete market size. Thereafter, market breakdown and data triangulation were used to estimate the size of segments and subsegments.

Let’s keep this Frostbyte streak going.

Penny is getting into deep detail about how the CCT Towers function and Weiss is lovingly listening to her as she combs Penny’s hair.

Penny: ... So then the Signal from Tower A is sent through it's network of Towers A1-A(x), Before transferring onto Tower B(x) - Tower B1, before Reaching Tower B!

Weiss: *Brushing Penny's Hair*That's an awful lot of towers. It seems inefficient.

Penny: The reason for so many towers is due to the limited range caused by Forests, Particles in the Air, Mountains, Bandwidth, and Power availability.

Weiss: Is there anyway around it?

Penny: Theoretically, if we had the capability to produce electricity without use of Dust, and lacking and Oxygen Rich atmosphere, we could create and Artificial Satellite Array that could bounce the CCT signals through space, and thus over any obstructions!

Weiss: Hmm. So if we could take something like a plant, and hook it up to a battery, like with a potato? Or like how plants send signals to each other using Mycelium?

Penny: ... A Photosynthesizing Eletrical generator ... If we made large panels that could allow the Chemical Processes to have as much sun as possible ... But then we'd need a way of reverting the chemicals to their reactive state without wasting too much energy ...

Weiss: What if you used the sun to Heat Water? Like to Solar Updraft plant My father Lobbied so hard against?

Penny: There'd be an issue-Ow!

Weiss: Sorry! continue, please.

Penny: Thermal Regulation and pressure may be an issue. Though perhaps we could use solids?

Weiss: How so? Oh! And do you want me to style your hair in anyway?

Penny: Twin Braids Please! As for using solids, there are certain metals and Metalloids that react to heat, electricity, and Radiation in unique ways ... It will take time to find a potential lead, but it is not yet an avenue we have traversed!

Weiss: Amazing, Penny, it truly is. I'm excited to see what you find out. If there is anyone for me to help out, let me know.

If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it’s the cleanest, most accessible form of energy, at least here on Earth. Driven by technological advances and mass production, solar energy on Earth is expanding rapidly. It seems likely that ETIs (Extraterrestrial Intelligence) using widespread solar energy on their planet could make their presence known to us. If other ETIs exist, they could easily be ahead of us technologically. Silicon solar panels could be widely used on their planetary surfaces. Could their mass implementation constitute a detectable technosignature? The authors of a new paper examine that question. The paper is “Detectability of Solar Panels as a Technosignature,” and it’ll be published in The Astrophysical Journal. The lead author is Ravi Kopparapu from NASA’s Goddard Space Flight Center. In their paper, the authors assess the detectability of silicon-based solar panels on an Earth-like habitable zone planet. “Silicon-based photovoltaic cells have high reflectance in the UV-VIS and in the near-IR, within the wavelength range of a space-based flagship mission concept like the Habitable Worlds Observatory (HWO),” the authors write. The HWO would search for and image Earth-like worlds in habitable zones. There’s no timeline for the mission, but the 2020 Decadal Survey recommended the telescope be built. This research looks ahead to the mission or one like it sometime in the future. Naturally, the authors make a number of assumptions about a hypothetical ETI using solar power. They assume that an ETI is using large-scale photovoltaics (PVs) based on silicon and that their planet orbits a Sun-like star. Silicon PVs are cost-effective to produce, and they are well-suited to harness the energy from a Sun-like star. Kopparapu and his co-authors aren’t the first to suggest that silicon PVs could constitute a technosignature. In a 2017 paper, Avi Loeb and Manasvi Lingam from the Harvard-Smithsonian Center for Astrophysics wrote that silicon-based PVs create an artificial edge in their spectra. This edge is similar to the ‘red edge‘ detectable in Earth’s vegetation when viewed from space but shifted to shorter wavelengths. “Future observations of reflected light from exoplanets would be able to detect both natural and artificial edges photometrically if a significant fraction of the planet’s surface is covered by vegetation or photovoltaic arrays, respectively,” Lingam and Loeb wrote. “The “edge” refers to the noticeable increase in the reflectance of the material under consideration when a reflected light spectrum is taken of the planet,” the authors of the new research explain. Satellites monitor the red edge on Earth to observe agricultural crops, and the same could apply to sensing PVs on other worlds. This figure shows the reflection spectrum of a deciduous leaf (data from Clark et al. 1993). The large sharp rise (between 700 and 800 nm) is known as the red edge and is due to the contrast between the strong absorption of chlorophyll and the otherwise reflective leaf. Image Credit: Seager et al. 2005. While Lingam and Loeb suggested the possibility, Kopparapu and his co-authors dug deeper. They point out that we could generate enough energy for our needs (as of 2022) if only 2.4% of the Earth’s surface was covered in silicon-based PVs. The 2.4% number is only accurate if the chosen location is optimized. For Earth, that means the Sahara Desert, and something similar may be true on an alien world. The authors explain, “This region is both close to the equator, where a comparatively greater amount of solar energy would be available throughout the year, and has minimal cloud coverage.” The authors also work with a 23% land coverage number. This number reflects previous research showing that for a projected maximum human population of 10 billion people, 23% land coverage would provide a high standard of living for everyone. They also use it as an upper limit because anything beyond that seems highly unlikely and would have negative consequences. On Earth, the entire continent of Africa is about 23% of the surface. The authors’ calculations show that an 8-meter telescope similar to the HWO would not detect an Earth-like exoplanet with 2.4% of its surface covered with PVs. If an ETI covered 23% of its surface with energy-harvesting PVs, would that be detectable? It would be difficult to untangle the planet’s light from the star’s light and would require hundreds of hours of observation time to reach an acceptable Signal-to-Noise (S/N) ratio. “Because we have chosen the 0.34 ?m–0.52?m range to calculate the impact of silicon panels on the reflectance spectra, the difference between a planet with and without silicon is not markedly different, even with 23% land cover,” the authors explain. Technological progress adds another wrinkle to these numbers. As PV technology advances, an ETI would cover less of its planet’s surface area to generate the same amount of energy, making detection even more difficult. This figure from the research shows the planet-star contrast ratio as a function of wavelength for2.4 % land coverage with PVs (blue solid), 23 % PVs (red solid) and 0% (green dashed) land coverage of solar panels. “This suggests that the artificial silicon edge suggested by Lingam & Loeb (2017) may not be detectable,” the authors write. Image Credit: Kopparapu et al. 2024. Solar energy is expanding rapidly on Earth. Each year, more individual homes, businesses, and institutions implement solar arrays. Those might not constitute technosignatures, but individual installations aren’t the only thing growing. China built a vast solar power plant called the Gonghe Photovoltaic Project in its sparsely populated Qinghai Province. It generates 3182 MW. India has the Bhadla Solar Park (2,245 MW) in the Thar Desert. Saudi Arabia has built several new solar plants and intends to build more. Other innovative solar projects are announced regularly. But will we realistically ever cover 2.4% of our planet in solar arrays? Will we need to? There are many questions. Generating solar power in the heat of the Sahara Desert is challenging. The extreme heat reduces efficiency. Building the infrastructure required to deliver the energy to population centres is also another challenge. Then consider that silicon-based PVs may not be the end point in solar panel development. Perovskite-based PVs hold a lot of promise to outperform silicon. They’re more efficient than silicon, and researchers frequently break energy records with them (in laboratories.) Would perovskite PVs create the same “edge” in a planet’s spectra? The authors didn’t consider specific technological advances like perovskite because it’s beyond the scope of their paper. The bottom line is that silicon-based solar arrays on a planetary surface are unlikely to create an easily detectable technosignature. “Assuming an 8-meter HWO-like telescope, focusing on the reflection edge in the UV-VIS, and considering varying land coverage of solar panels on an Earth-like exoplanet that match the present and projected energy needs, we estimate that several hundreds of hours of observation time is needed to reach a SNR of ~5 for a high land coverage of ~23%,” the authors write. The Bhadla Solar Park is a large PV installation that aims to generate over 2,000 MW of solar energy. Image Credit: (Left) Google Earth. (Right) Contains modified Copernicus Sentinel data 2020, Attribution, https://commons.wikimedia.org/w/index.php?curid=90537462 The authors also wonder what this means for the Kardashev Scale and things like Dyson Spheres. In that paradigm, ETIs require more and more energy and eventually build a mega engineering project that harvests all of the energy available from their star. A Dyson Sphere would create a powerful technosignature, and astronomers are already looking for them. But if the numbers in this research are correct, we may never see one because they’re not needed. “We find that, even with significant population growth, the energy needs of human civilization would be several orders of magnitude below the energy threshold for a Kardashev Type I civilization or a Dyson sphere/swarm which harnesses the energy of a star,” they conclude. “This line of inquiry reexamines the utility of such concepts and potentially addresses one crucial aspect of the Fermi paradox: We have not discovered any large-scale engineering yet, conceivably because advanced technologies may not need them.” The post Could Alien Solar Panels Be Technosignatures? appeared first on Universe Today.

Revenge of GLaDOS

Being both one of the hl-verse's greatest minds AND a literal computer, GLaDOS is always thinking one step ahead. Her goal; reconnect Arpeture with outdoor sensors in order to find out what had happened.

With limited information, and only her own murderous rampage to go on, she needed to figure out what the scope of the world is currently like. As such, she is constantly collecting data and plotting a path forward.

Her first initiative; Escape Arpeture. What we don't know, is what she saw once she was outside. We do know that an unidentified android recovered Chell and GLaDOS. Theoretically, this is likely due to AEGIS.

Aegis probably has more external sensors, solely because it is a glorified facility security guard. The damage done to it is likely from the fallout of combine forces, zombified and head crabbed peoples, and survivors taking the occasional shelter in some of the warehouses.

It should be noted, that over the course of the L4D series, rarely are people killed by high-tech devices. If my theory is correct, it's because the Arpeture facilities have a clear understanding of what does and what does not constitute a murderous zombified creature, or a headcrab.

It's also possible that they collected samples from these subjects in order to identify the cause of zombification AND figure out if there's a way to stop it.

- Identify whether or not some of the Cave Johnson recordings are due to defense against zombified invaders.

- make a clear delineation between human stasis subjects, and zombified test subjects.

GLaDOS needed to determine how to free an object from the stasis fields, as all crafted objects would be vaporized on contact with the fields. Since Chell has the ability to bypass the fields, it's on her to determine what is, and is not possible.

Enter Companion Cube: Companion Cube would eventually be vaporized by this barrier, so we must determine if the test chamber will allow exit by another facet. The Incineration chute. This should give incentive to Chell for her subconscious processes at least to determine a way to escape from such a fate herself.

All virtual headcrab companions will be pushed into the incinerator chute. They should be able to survive. And they deserve it anyway. In this way; I should be able to *free* myself.

During the course of Portal 2 GLaDOS determined minimal functionality and duration from being lodged into a potato, this information could be collected and fed to a personality core launched into space. They would likely stay in orbit perpetually and be able to be recovered eventually, worst case scenario. However, there's a good chance that at least one core can connect with a satellite, connect to it, recharge from the solar panels, and re-establish communications with earth AND Arpeture.

Also, they deserve this.

While waiting for companion cubes to pull their virtual heads out of their virtual butts, we shall reconnect the various facilities back to the mainframe, and locate the stasis subjects.

It is not clear if test subjects "Chel" and "Mel" will return to the facility, or have a need to return to the facility. For now, they will be left to their own devices and hopefully, they will be able to reconnect the above ground sensor array, and setup communications with the Personality cores.

It is lucky that Mr. Johnson was able to coat enough of the above ground testing facilities with white paint. It is lucky that some of the paint transfer tubes also lead to the above ground. It'll be lucky if some of *those* tubes still work.

Is your Spacecraft powered by a Reliable Power Supply?

Satellites and spacecraft, as with any other equipment, need a reliable power supply to power the onboard devices.

Any satellite mission is based on the orbit type, expected mission life, potential radiation hazards, type of payload, weight, and cost, each varying the power supply requirements.

Types of power used

Satellites are the spacecraft that orbit the Earth and are close enough to the Sun to be able to use solar power. Solar panels convert the Sun’s energy into electricity stored in an on-board battery to power the spacecraft.

When solar power doesn’t work, and for short missions, power stored in batteries is used.

Spacecraft batteries are designed to be tough. They need to work in extreme environments in space and on the surfaces of other worlds. However great the amount of charge they can store, and regardless of their size and durability, these batteries need to be recharged many times.

The importance of Power Supply Testing

Any disruption in the power supply can have a cascading effect on the performance of the devices onboard, even leading to the satellite falling apart. Also, the power supply degrades over time due to heating from the Sun and radiation effects in space. However large solar arrays be used, or alternative power sources be used, they need to be tested for reliable performance over the mission’s stay in space.

The need for an appropriate Automated Test Equipment (ATE)

The best way to accomplish this is by using Automated Test Equipment (ATE) equipped with suitable types of equipment.

A great example is the DC-DC converter ATE for Space applications from MELSS which consists of an Industrial PC-based unit with Digital Add-On modules.

Features of the ATE for Space Applications from MELSS

The customer-end UUT unit is interfaced with the DC Source, DMM, DC Load, and Oscilloscope. The instruments are interfaced with the Industrial PC (IPC) and controlled through the application software via USB/RS232 communication interfaces.

The IPC controls and collects the measured Data from the different devices like the DMM, DC Load, DC source, and Oscilloscope for processing and display. The I/O modules in the IPC are controlled and operated to achieve the necessary test conditions.

A custom-designed interface box with a Relay Matrix arrangement meets the necessary switching requirements.

The GUI-based application Software captures the test sequence and acquires & controls the parametric values from the measurement instruments and the UUT. The Test report is generated in a non-editable format for the sequence of tests, master parametric value, measured value, and the status of the test (Pass/Fail). A self-test module ascertains the serviceability status of the test and measurement instruments and the UUT.

The Challenges and Potential of AI in Space Applications

Overcoming Obstacles to Bring AI Onboard Satellites

Space exploration has always pushed the boundaries of human knowledge and technology. In recent years, there has been a growing interest in integrating artificial intelligence (AI) and machine learning (ML) into space-related applications. However, the implementation of AI in space comes with its own set of challenges.

From power management to radiation protection, the environment of space poses unique obstacles that must be overcome. This article explores the difficulties of running AI in space and the potential benefits it offers.

Power Management and Radiation Protection

One of the major hurdles in running AI onboard satellites is power management. Advanced processors used in AI applications are power-hungry, requiring large solar panels and extra batteries to operate efficiently. Additionally, the radiation in space can pose a threat to electronics, potentially frying them.

The demands that AI devices place on power management are new to the space industry, making it difficult to find efficient and small form factor power and management parts that can supply power to AI devices in space.

Software Adaptation for Space Missions

Running AI in space also requires software modifications. Space missions demand AI techniques that can crunch data with limited power and memory. The software used for AI applications on Earth must be adapted to run on satellites, taking into account the constraints of the space environment.

This presents a unique challenge as electronic companies producing AI chips have not fully considered the specific requirements of space missions.

Impressive Potential Benefits

Despite the challenges, there are certain missions where the potential benefits of onboard AI are too impressive to ignore. For example, an algorithm trained to spot ships could downlink ship locations, sizes, and headings directly to the Coast Guard, eliminating the need to downlink enormous ocean scenes from an Earth-observation satellite. Onboard AI could also improve spacecraft performance by identifying and remedying problems such as latchups, a type of short circuit, through power cycling or other means.

Enhanced Autonomy and Data Processing

Further autonomy supported by AI will be crucial for complicated long-duration platforms or long-distance missions where human interaction is limited. AI and machine learning can also play a significant role in processing or pre-processing data from remote-sensing satellites. By optimizing devices for AI and machine learning, satellites can transmit the most important datasets first and compress the remaining data for onboard storage, improving data transmission efficiency.

Creative Solutions and Space-Qualified Components

To make AI viable for space applications, companies are developing creative solutions and space-qualifying components. Shielding terrestrial components and space-qualifying AI-optimized chips and circuit boards are some of the approaches being taken. For example, Mercury Systems has co-developed a space-qualified processing board for field programmable gate arrays, while OrbiSky is working on high-performance, secure AI components for spacecraft and drones.

Singapore-based Zero Error Systems produces hardware and software to protect space-based electronics from latchups and errors in commercial memory devices.

Testing and Mitigating Radiation Effects

One of the key challenges in bringing AI onboard satellites is understanding and mitigating the effects of radiation on AI-optimized chips. Voyager Space Technology Systems works with universities to investigate the impact of radiation on these chips and develops strategies to mitigate the risks. Testing involves identifying devices that exhibit destructive single event effects and finding ways to mitigate soft errors caused by high-energy particles striking spacecraft.

Bringing AI onboard satellites is a complex and ongoing endeavor. While there are challenges to overcome, the potential benefits of onboard AI in space applications are immense. From improving spacecraft performance to enhancing data processing and analysis, AI has the potential to revolutionize space exploration.

With the development of space-qualified components and creative solutions, the integration of AI in space is becoming more feasible. As technology advances and our understanding of the space environment deepens, the future holds exciting possibilities for AI in space.

Firefly will launch its fourth Firefly Alpha launcher today from SLC-2W at Vandenberg, California. It is an all composite construction LOX/methane rocket with 3D printed engines. Onboard will be a satellite called Tantrum, a technology demonstrator for Lockheed Martin which will test an Electronically Steerable Antenna (ESA)(I don't know if they mean a synthetic aperture antenna or something else) and a shorter commissioning period to calibrate the sensor quicker. The satellite bus (chassis) is a Nebula bus built by Terran Orbital, which has a Hall effect electric ion rocket motor of 1.1mN (mili-newton), for station keeping etc, and (in this case) fixed solar array panels.

Launch is scheduled for 17:18GMT, coverage on NSF...

New Solar Array Design Saves Space - Technology Org

NASA’s Compact Telescoping Array will conserve commercial satellite launch costs by reducing solar array bundle dimensions.

Northrop Grumman’s first major customer for its new, NASA-based Compact Telescoping Array (CTA) solar panel design is Airbus, which is using the panels on its new OneSat communication satellites, shown in this artist’s rendering. Image credit: Airbus Defence and Space Ltd.

Sending astronauts almost 240,000 miles to the Moon was the technical challenge of the day half a century ago. Carrying the cargo necessary to send astronauts 40 million miles to Mars will be no less daunting in the next decades.

Total reliance on traditional combustion-based engines would require too much fuel, so NASA is considering scaling up a newer technology, called solar electric propulsion. But this will require massive solar panels.

A team of engineers at Langley Research Center started with the design for the massive, collapsible solar panels on the International Space Station and then figured out how to reduce the bulky housings for the solar blankets and the central boom that supports them. Image credit: NASA

To address that challenge, several years ago, a team at NASA’s Langley Research Center in Hampton, Virginia, started imagining new ways to stow and deploy large, flexible solar arrays.

“If you’re really serious about hauling tens of tons of cargo to Mars, you can’t do it efficiently with traditional chemical thrusters,” said Richard Pappa, who managed the project at Langley.

While using solar-powered electric thrusters would dramatically reduce the amount of fuel the craft would have to carry, the amount of space the stowed arrays would occupy in the rocket during launch could be prohibitive.

The team started with the design for the International Space Station’s solar arrays. These are supported along a central boom, and the solar blankets fold into a compact bundle. But the boom, made of a foldable lattice structure, is contained in a large, heavy canister, and the solar blankets also require a bulky housing.

Instead, the Langley team proposed a central mast that would “telescope,” extending by means of a smaller, screw-like mechanism and eliminating the need for a canister.

The packaging efficiency of the resulting design, known as the Compact Telescoping Array (CTA), reduces the volume of a stowed solar array by about a third.

When Northrop Grumman’s final version of the CTA is collapsed, the solar blankets and central mast are tightly packed into the smallest possible package. Image redit: Northrop Grumman Corporation

In 2015, the design captured the attention of Orbital ATK Inc., now part of Northrop Grumman Corporation. Langley issued two Small Business Innovation Research (SBIR) contracts to the company Angstrom Designs, with Orbital ATK as the subcontractor, to build and test experimental units, while the Air Force supplied additional SBIR funding.

By 2021, Northrop Grumman found its first CTA customer, with Airbus Defence and Space ordering enough arrays to power its new OneSat communication satellites.

Several of the world’s largest satellite communications companies have already commissioned OneSat satellites, including Britain’s Inmarsat, Australia’s Optus, Japan’s JSAT, and the multinational Intelsat.

For all these clients, the compact packaging will save on launch costs by allowing more satellites to be launched at once.

“While most launches carry just one or two satellites, the CTA smartly tucks into the satellite bus design, so three satellites can fit on one rocket,” said Alan Jones, flexible solar array product director at Northrop Grumman.

Jim Spink, program manager at the Northrop Grumman facility in Goleta, California, where the arrays are produced, said he and Jones saw increasing potential for the CTA as the design progressed.

“Now it’s become a major product,” he said. “That push from NASA and the SBIR funding sparked this innovative class of solar array, which will enable higher-performance spacecraft designs. We’re excited to see where it goes next.”

Space Cat Nonsense

It's a good thing that cats don't have the ability to live in space and need food and water to survive imagine if they didn't and a recurring problem for satellite internet are the cats we accidentally unleashed in space during the early days of space exploration and testing who keep bapping asteroids and satellites for fun and misaligning the latter or sending them into decaying orbits so the insurance companies we have in our timeline/reality that work to 'insure' private satellite launches that aren't actually willing to pay out if anything happens apparently don't get to scam other companies out of money like they do irl because the risk of a gatto playing with their new scratching post (the solar panels of part of a several hundred million dollar satellite array) are too high and people would call them out on their bullshit too much and all astronauts in the ISS would be queried to ask if they would be willing to shoot a cat if it threatened the station's operation because the little shits would sleep atop it scratch up its panels nestle in the docking bays and whine to be let in and eat all of your food and bullets are probably cheaper than catfood and extra water although I guess this whole point is moot anyway since the population would probably collapse by the 1990s or something anyway through excessive inbreeding old age and or dispersal through the cosmos.
