Super cool experience to visit JPL and learn about space missions and how they bring back so much information about space and our planetary system!

Space is fake. We are at the center. Nasa uses green screen, cgi, harnesses, wires, zero g planes to fake the ISS. It is a Masonic club. They are here to fool us and hide the one that designed us. Hollywood, occult, masons it's all connected. Jesus Christ wins. Neil de liar is a bad actor. Find a new one for the next generation.

There are no words to describe how incredible it is to be able to know a NASA building, especially JPL, where extremely competent people come together for the sake of science for the evolution of humanity. The building itself is from Caltech, but everything that is done in it is for NASA, so it can be said to be in fact in it. The guided tour is for hardcore nerds, lasts 3 hours and has a lot of explanation. I was fascinated and ended the tours wishing there was more, but my wife was tired at the end of the tour. So consider this, not for everyone, but even tired, my wife loved the visit. No wonder, it is a great privilege to know a little more about the place that sends probes and satellites into space, it is the central control of everything that man sent to space and is from the moon ahead, with people who are very serious about everything they do, being able to see it all up close is a tremendous privilege, especially for children, who can get in touch with such deep subjects while they are very young. The souvenir shop is also very cool, several authentic NASA swags to flaunt around the world. Plan your visit in advance and schedule on the site, do not miss the opportunity to meet the JPL! ---- Português BR Não existem palavras para descrever o quão incrível é poder conhecer um prédio da NASA, especialmente o que abriga a JPL, onde pessoas extremamente competentes se juntam em prol da ciência para a evolução da humanidade. O prédio em si é da Caltech, mas tudo que é feito nele é para NASA, então pode-se afirmar que se está de fato nela. O tour guiado é para nerds hardcore, dura 3 horas e tem muita explicação. Eu fiquei fascinado e achei pouco, minha esposa estava cansada no final do tour. Então leve isso em consideração, não é para todos os gostos, mas mesmo cansada, minha esposa adorou a visita. Também não é para menos, é um privilégio muito grande poder conhecer um pouco mais do lugar que manda sondas e satélites para o espaço, é o controle central de tudo aquilo que o homem mandou pro espaço e está da Lua à diante, com pessoas que tem uma seriedade muito grande em tudo aquilo que fazem, poder ver tudo isso de perto é um privilégio enorme, especialmente para as crianças, que podem entrar em contato com assuntos tão profundos enquanto ainda são bem jovens. A lojinha também é bem legal, vários swags autênticos da NASA para ostentar mundo afora. Planeje antecipadamente a sua visita e agende no site, não perca a oportunidade de conhecer a JPL!

Went on a field trip with my son's 4th grade class! The tour staff is excellent! Spoke loud enough for everyone to hear, kept the kids quiet when needed, organized group picture opportunities, and answered many questions! It was so exciting because we were able to see the Mars 2020 Rover!!!

I have a serious question who wrote the mars rovers AI and why did they make it sing happy birthday to itself? What’s the story behind it? And will we ever send something to fix the rover?

Jasper Rick | Sep 8, 2019
James Kurien | Sep 8, 2019

The flight software for the rovers is written by JPL employees. There is no plan to send something to fix any rovers - if you're going to spend money to send something all the way to Mars, you might as well send a newer rover. There is a new rover launching in July 2020. Two of the AI-ish systems on recent rovers are Aegis, which chooses remote sensing/imaging targets, and Autonav, which allows the rover to drive autonomously. Creating automated driving software for rovers is somewhat different than what people are trying to do with automobiles on Earth. Rovers are much slower and there's no traffic. On the other hand, there are no marking, no GPS and the terrain can be treacherous.

Hi I'm a 11 year old Sri Lankan student. I just want to know how many roket missions you have sent to Mars.

Chamari Wickramarachchi | Jan 10, 2022
Kevin horton | Jan 10, 2022

Hey Chamari! JPL has directly helped a total of 20 Mars missions (unless I forgot one?). Most were satellites, but 5 were rovers. Here is the list: Mariner 3-4 to Mars Mariner 6-7 to Mars Mariner 8-9 to Mars Viking to Mars Mars Observer Mars Pathfinder Mars Climate Orbiter Mars Polar Lander/Deep Space 2 Mars Global Surveyor 2001 Mars Odyssey Mars Spirit Rover Mars Opportunity Rover Mars Reconnaissance Orbiter Phoenix Mars Lander Mars Curiosity Rover Mars InSight Lander Mars Perseverance Rover (+ Ingenuity helicopter) I hope this makes you even more curious about space :)

The Jet Propulsion Laboratory is a federally funded research and development center and NASA field center. The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA's Deep Space Network.

What happens when a wave is constructively superimposed infinite times except light waves

Mr. PSE | Sep 8, 2019
Ryan X | Sep 8, 2019

Constructive interference occurs when two identical waves are superimposed in phase. Destructive interference occurs when two identical waves are superimposed exactly out of phase. A standing wave is one in which two waves superimpose to produce a wave that varies in amplitude but does not propagate.

Does male physicist name Jessie work here?

Angel Mendez | Sep 8, 2019
Martin Cabello III | Sep 8, 2019

Yes. The strings or the fabric that holds space time together in (M-Theory) would be the energy that creates the attraction that holds your biological vessels quantum particles together to give it mass so it can be a watchman and perceive time. Without that Quantum entangled attraction (strings of energy) that holds all mass together it would just return to the light where space has no time.

How can we become CEO of NASA what do we study?

prasanthi kumari | Sep 8, 2018

Study Everything. Updated: Energy frequencies and vibrations fuel the universe and is light. Light is the gas that fuels the time in our universe's space. Solar alignment is our GPS since they dictate specific times in the space-time continuum. Gravitational lensing proves you can bend light. If you can bend the light of space-time then you can obviously warp space-time to create wormholes for time travel so light can jump across the lights fibonacci sequence that exists inside of the universes PI. Since time is light and light never ages it's infinite life is a circle. Light exists at the beginning of time throughout the middle of time and at the end of time all at the same time. A wormhole (German ball lightning) is light created out of itself. Making time travel possible for light and information. A work in progress by Martin Cabello III.
