NASA is everywhere – our space technology turns up in nearly all corners of modern life. The world has come to rely on GPS signal correction software created by NASA, which enables precision agriculture, airplane navigation, smartphones, Earth science and much more. A lightweight, high-pressure tank NASA invented to hold rocket fuel now stores life-saving oxygen to keep pilots, firefighters and intensive care patients breathing — not to mention gases that power city buses and even paintball guns. Fitness enthusiasts may be surprised to learn about NASA’s contribution to the Bowflex Revolution resistance-exercise home gym.
How do you build a spaceship? It’s not easy – because space is hard. It’s endless vacuum, hot and cold at the same time, streaked with radiation – and you have to fly at eight kilometres per second just to get there. It takes clever engineering – and costly research and development – to operate in orbit. Space is risky, but past payoffs have been vast. Our track record lets us manage that risk, balancing it with chances for rich rewards.
We are Europe’s space agency, enabling its 22 Member States to achieve results that no individual nation can match. we combines space mission development with supporting labs, test and operational facilities plus in-house experts covering every aspect of space, supported through the our Basic Activities.

Revisit the April 18, 2018, launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) aboard a SpaceX Falcon 9 rocket. TESS is already scanning the skies, identifying planet candidates that may be orbiting distant stars. https://go.nasa.gov/2Q3J9ei
TESS is NASA’s next step in the search for planets outside of our solar system, including those that could support life. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. TESS will survey 200,000 of the brightest stars near the sun to search for transiting exoplanets.
Artificial Intelligence also known as Machine Intelligence or Intelligence displayed by Machines is a broad concept which is essentially important for our children to learn about, Science and technology are reaching out to new possibilities in developing new AI products every day
Here are a some few Examples of AI for kids which will help them to get a glance about what Artificial Intelligence is all about.
Congress passed the National Aeronautics and Space Act, on July 16 and President Eisenhower signed it into law on July 29, 1958. NASA opened for business on Oct. 1, 1958, with T.

But, now Jarvis is Vision and at present his AI is Friday. So, i have tried to build same kind of Artificial Intelligence in Python.
RIght now, it a basic one. Which will greet, open C drive folders and good bye.
On Feb. 12, NASA centers across the country hosted “State of NASA” events, following President Trump’s Fiscal Year 2019 budget proposal delivery to the U.S. Congress. The events included an address, by acting NASA Administrator Robert Lightfoot, to the agency’s workforce, from NASA’s Marshall Space Flight Center, in Huntsville, Alabama. During his speech, Lightfoot highlighted how the budget would help the agency achieve its goals for space exploration.
How can you train yourself to be a quantum detector? Quantum interactions happen at impossibly small scales. But the life-size effects are all around you. You can detect quantum mechanics all over — if you know how to look for it.
ADVANCED SCIENTIFIC NOTE: Quantum mechanics would be much more obvious if we had very sensitive eyes. If your eyes identified each photon individually, you would see them land as described in the video, and only build up to this wave pattern. The pattern that we see can be explained classically by waves, it is *ultimately* a quantum phenomenon. The only reason it’s hard to tell is because our light detectors (eyes) aren’t quite sensitive enough.

SCIENTIFIC NOTES:
* The relationship between information and energy comes from Landauer’s Principle, which connects the erasure of information and energy. But, more generally changes in information (e.g. recording information) are related to changes in energy. I will talk more about this in a future episode about the physics of memory, and why you will forget everything you ever knew! https://en.wikipedia.org/wiki/Landauer%27s_principle
* The numbers calculated in this video give a lower limit on the energy to record a particular amount of information, but to create a more permanent storage of information would require more energy.
* Retina display resolution, as it’s name implies, is similar to the eye’s resolution.
Scientific notes:
Stellar mass black holes vs. supermassive black holes
* Stellar mass black holes form from the collapse of massive stars at the ends of their lives, so they have roughly the same mass as a star. Supermassive black holes are physically identical to their smaller counterparts, except they are 10 thousand to a billion times the size of the sun. However, their formation is more of a mystery. They may form from the merging of smaller black holes. http://astronomy.swin.edu.au/cosmos/S/Supermassive+Black+Hole
Supermassive black holes at the center of galaxies
* Almost every large galaxy has a supermassive black hole at its center, but researchers are not yet sure (https://jila.colorado.edu/research/astrophysics/black-holes-galaxies) why that’s the case, how they originate, and what their role is in the creation and evolution of galaxies.
Why are stars different colors?
* The color of a star depends on its temperature (http://www.atnf.csiro.au/outreach/education/senior/astrophysics/photometry_colour.html). The hotter a star, the higher energy its light will be. Higher energy/temperature corresponds with the blue end of the visible spectrum and lower energy/temperature corresponds with the red end.
How does dark matter make stars spin faster?
* In the 1960s, astronomers Vera Rubin and Kent Ford noticed that stars at the edges of galaxies were moving just as fast as stars at the center, which surprised them: it appeared that the force of gravity causing stars to orbit the center of the galaxy was not weakening over distance. Their observation implied that something else, distributed throughout the galaxy, was exerting a gravitation pull. We now know that that “something else,” now named dark matter, accounts for about 85% of the matter in the universe. (It existence was inferred in the 1930s, when the astronomer Fritz Zwicky(http://www2.astro.psu.edu/users/rbc/a1/week_10.html) noticed that galaxies in clusters were moving faster than they should.)
Size of the universe
* The universe is only 13.8 billion years old, but has a radius of about 46 billion light-years. If nothing can travel faster than the speed of light, how can that be? The expansion of the universe, driven by dark energy, is causing distances between objects to grow. Note that it is not moving those objects apart; rather, it is increasing the amount of space between them. https://phys.org/news/2015-10-big-universe.html
Cosmic webs
* Galaxies are not distributed randomly (http://skyserver.sdss.org/dr1/en/astro/structures/structures.asp) in space; instead, clusters of galaxies form web-like patterns. These webs consist of filaments, where dark matter and ordinary (baryonic) matter are concentrated, and voids, where galaxies are scarce. Researchers believe that these large-scale structures grew out of minor fluctuations in density at the beginning of the universe.
Composition of the early universe
* Moments after the Big Bang, the universe formed the nuclei for what would be come the universe’s hydrogen and helium atoms, with one helium nucleus for every 10 or 11 hydrogen (http://umich.edu/~gs265/bigbang.htm). When the first stars formed, there were no heavier elements — those elements formed inside stars.
String Theory Landscape
* The String Theory Landscape is a theory that the universe we live in is one of many universes. It attempts to explain how certain constants of nature seem “fine-tuned” for life, which contradicts the anthropic principle, or the notion that we humans hold a special place in the universe. https://www.scientificamerican.com/article/multiverse-the-case-for-parallel-universe/%0A
Disintegration of the universe
* In the future Degenerate Era of the universe, as space-time expands and stars burn up, all of the matter in stars will be consumed by black holes. But even black holes are not forever. Stephen Hawking theorized that black holes will slowly radiate away their mass in what is now called Hawking radiation until they too dissipate away. http://www.nytimes.com/books/first/a/adams-universe.html

This short animation explains the relative sizes of the Rosetta spacecraft and comet 67P/Churyumov–Gerasimenko. Rosetta is 32 m from tip to tip of the solar wings. The comet measures 4.1 km along its longest length, 128 times the width of Rosetta.
Unlike typical artist’s impressions, this image is scaled to convey the vast difference in size between Rosetta and the comet, even when the spacecraft is in a close 10 km orbit, as depicted here.
Rosetta reached 10 km distance from the comet centre by October 2014.
What happens after Rosetta arrives at comet 67P/Churyumov–Gerasimenko? This animation describes the key dates for the next set of manoeuvres that will bring Rosetta even closer to the comet between August and October.
After arriving on 6 August, Rosetta will follow a set of two, three-legged triangular trajectories that require a small thruster burn at each apex. The legs are about 100 km long and it will take Rosetta between three and four days to complete each one.
The first triangle is conducted at a distance of about 100 km from the comet, the second at around 50 km. Then Rosetta will switch to a ‘global mapping phase’ at an altitude of about 30 km. During this period, it will make a ‘night excursion’, whereby the ground track of the spacecraft will be on the night-side of the comet (with the spacecraft still fully illuminated the Sun).
In October Rosetta will transfer to a close mapping phase to observe the comet from a distance of 10 km. The spacecraft will move even closer to dispatch lander Philae to the surface in November.
In this animation the comet is an artist’s impression and is not to scale with the spacecraft. The comet rotation is not representative (67P rotates once per 12.4 hours). Dates may be subject to change.
This short animation explains the relative sizes of the Rosetta spacecraft and comet 67P/Churyumov–Gerasimenko.
Rosetta is 32 m from tip to tip of the solar wings. Assuming the comet measures about 4 km across, that’s 125 times the width of Rosetta.
Unlike typical artist’s impressions, this image is scaled to convey the vast difference in size between Rosetta and the comet, even when the spacecraft is in a close 10 km orbit, as depicted here.
Rosetta arrives at the comet at an altitude of 100 km in the first week of August, and will move progressively closer over the following two months, with the intention to orbit at an altitude of just 10 km, depending on the comet’s activity. For Philae’s deployment in November, Rosetta will come to within a few kilometres of the surface.
The comet depicted in this animation is an artist’s impression.

Visualisation of how the Rosetta spacecraft wakes up from deep space hibernation, 673 million kilometres from the Sun, on 20 January 2014.
Prior to entering hibernation on 8 June 2011, Rosetta was oriented so that its solar arrays faced the Sun, and it began rotating once per minute for stability. The only devices left running were its computer and several heaters.
Rosetta’s computer is programmed to carry out a sequence of events to re-establish contact with the Earth on 20 January, starting with an ‘alarm clock’ at 10:00 GMT. Immediately after, the star trackers begin to warm up. Around 6 hours later the thrusters are fired and the slow rotation stops. A slight adjustment is made to Rosetta’s orientation to ensure that the solar arrays now face the Sun. Then the star trackers switch on to determine its attitude. The spacecraft rotates towards Earth, and the transmitter is switched on. Then Rosetta’s high-gain antenna points to Earth and the signal is sent. The journey takes 45 minutes before the signal is received and mission controllers can begin to check Rosetta’s health, ready for the next phase of the mission.
The first opportunity for receiving a signal on Earth is between 17:30 GMT and 18:30 GMT.
