Pixxel
Pixxel (pik·sl) is a US-Indian private space technology company building a constellation of Hyperspectral imaging, hyperspectral imaging satellites into a sun-synchronous orbit. History Pixxel was founded by Awais Ahmed and Kshitij Khandelwal in 2019 while studying at BITS Pilani. In 2023, the company was named one of TIME's 100 best Inventions in the Sustainability category and a Technology Pioneer by the World Economic Forum in 2024. It was Asia's only space startup to qualify for the 2019 Techstars Starburst Space Accelerator in Los Angeles. Pixxel's mission is to build a health monitor for the planet. Pixxel's hyperspectral satellites are designed to detect, monitor, and predict threats invisible to satellites in orbit today. This is made possible by the hyperspectral cameras' ability to capture additional wavelengths of light across a broad and continuous range on the electromagnetic spectrum beyond those typically observed by conventional satellite imaging systems.

Hyperloop
Hyperloop is a proposed high-speed transportation system for both passengers and freight. The concept was published by entrepreneur Elon Musk in a 2013 white paper, where the hyperloop was described as a transportation system using capsules supported by an air bearing, air-bearing surface within a low-pressure tube. Hyperloop systems have three essential elements: tubes, pods, and terminals. The tube is a large, sealed Vacuum#Vacuum-driven machines, low-pressure system (typically a long tunnel). The pod is a coach at atmospheric pressure that experiences low Drag (physics), air resistance or friction inside the tube using Maglev, magnetic propulsion (in the initial design, augmented by a ducted fan). The terminal handles pod arrivals and departures. The hyperloop, in the form proposed by Musk, differs from other Vactrain, vactrains by relying on residual air pressure inside the tube to provide lift from Aerofoil, aerofoils and propulsion by fans; however, many subsequent variants ...

SpaceX Facilities
, SpaceX operates four launch facilities: Cape Canaveral Space Launch Complex 40 (SLC-40), Vandenberg Air Force Base Space Launch Complex 4, Vandenberg Space Force Base Space Launch Complex 4E (SLC-4E), Kennedy Space Center Launch Complex 39A (LC-39A), and Brownsville SpaceX Starbase, South Texas Launch Site (Starbase). Space Launch Complex 40 was damaged in the AMOS-6 accident in September 2016 and repair work was completed by December 2017. SpaceX believes that they can optimize their launch operations, and reduce launch costs, by dividing their launch missions amongst these four launch facilities: LC-39A for NASA launches, SLC-40 for United States Space Force national security launches, SLC-4E for polar orbit, polar launches, and South Texas Launch Site for commercial launches. COO Gwynne Shotwell stated in 2014 that "we are expanding in all of our locations" and "you will end up seeing a lot of SpaceX launch sites in order to meet the future demand that we anticipate." , Spac ...

Falcon 9
Falcon 9 is a Reusable launch system#Partial reusable launch systems, partially reusable, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured in the United States by SpaceX. The first Falcon 9 launch was on June 4, 2010, and the first commercial resupply mission to the International Space Station (ISS) launched on October 8, 2012. In 2020, it became the first commercial rocket to launch humans to orbit. The Falcon 9 has been noted for its reliability and high launch cadence, with successful launches, two in-flight failures, one partial failure and one pre-flight destruction. It is the most-launched American orbital rocket in history. The rocket has two-stage-to-orbit, two stages. The first (booster) stage carries the second stage and payload to a predetermined speed and altitude, after which the second stage accelerates the payload to its target orbit. The Booster (rocketry), booster is capable of Vertical takeoff, vertical landing, landing vertically to fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SI Imaging Services

A Hyperspectral Image Of Senegal's Saloum Delta From Pixxel
A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is '' a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, '' a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest known ancestor of A is ''aleph''—the first letter of the Phoenician ...

Multispectral Imaging
Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or detected with the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range (i.e. infrared and ultraviolet). It can allow extraction of additional information the human eye fails to capture with its visible receptors for red, green and blue. It was originally developed for military target identification and reconnaissance. Early space-based imaging platforms incorporated multispectral imaging technology to map details of the Earth related to coastal boundaries, vegetation, and landforms. Multispectral imaging has also found use in document and painting analysis. Multispectral imaging measures light in a small number (typically 3 to 15) of spectral bands. ''Hyperspectral imaging'' is a special case of spectral imaging where often hundreds of contig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
