    He mentions that the dragonfly will have a harder time sending data back to earth why not do what they did with Cassini and it’s probe? Send a second ship with a satellite so the data could be sent back faster. With Elon Musks Falcon Heavy it should reduce the cost to send it? It’s just a thought I don’t know much about what all goes into sending a probe but it seems logical in cutting down the wait for extra components needed on dragonfly.

    a documentary told me on titan if your space suit had a rip you wouldnt die immediately in fact you could have plenty of time to get to safety because there is little radiation its just the cold if you did stay out for too long you would get hypothermia

    Titan is a cold dark dawn planet, it obtains enough radiation and body mass to sustain a core to flurish, almost the right elements, spewed to the surface, as on Earth. Land drones will need cold thermal resistance limbs. Artifical gravity is needed badly here.

    Today, 3/3/2021, 5:21 P.M GMT+8 (West Malaysia) as of writing. Half an hour ago or so, my father came back early. As always, he complained about everything he didn't like. It went on and on until he was furious, really furious. At one point, I couldn't understand the instructions my father was telling me. He did it. It wasn't the first time he hit me. He's been abusing me and my sister for the last 14 years of our lives. Even when we were little babies, he would hit us for crying. We cried more, and he hit more. Today was it. Tensions were escalating at an unbelievable pace. I *snapped*. I defended myself. It was my second time I've outright attacked him. My sister was screaming and crying. She tried to deescalate the situation but to no avail. He started using objects to scare me into submission. I didn't flinch. My poor sister would be devastated if I kept attacking. I backed off. My dad, years and years of dominance supported by fear later, has finally learned that I have the power to fight back, possibly end him. He was smart enough to not anger me anymore, but still verbally abused us. After an eternity, he would leave. My sister, she's never screamed and cried so loudly. I could not feel my hands and had slight pain in my back from him holding me against a kitchen counter. I'm now contemplating finally calling CPS or the police after 14 years. If anyone has any advice, please give me some, preferably Malaysian laws and things regarding applying for a student visa for studying at a Singapore government high school. I'm trying to go overseas to study in a country with a better education system that is suited for me.

    That's so thrilling! I'd like to see Dragonfly coupled with a lander capable of hot-drilling the ice and launching an AOV/ROV, similar to the Icefin ROV used in Antarctica, or the slightly dorkier BRUIE robot developed at JPL. Plus whatever orbital platforms might play supporting roles. It can wait until we get back the Mars cores collected by Persie. A bunch of idiots were ripping on the Chinese Change'E mission's successful Lunar SRM. It was a sweet achievement, and it's a shame the US can't work with them. I reminded them that it took the USSR 's answer to Apollo, the huge Luna program, to scoop and return a mere ten ounces from this side of the moon (and proved that the Russians just can't build sexy spacecraft).

    Since this has a power source with no moving parts that can’t be turned off during the years long cruise to Saturn, perhaps the energy could be used to run some ion thrusters that could shorten the trip. The extra thrust could also be used to take more mass there, like an Titan orbiter with a higher power transmitter to act as relay for data from the surface.

    Guys this is not true. These people killing humans being on Earth and they looking for life on Mars, Do you really thinking like this. So that mean, life on Mars was ended by Coronavirus and we need to take the vaccine to live on Earth or we will be Extinction like Mars, what a smart idea. Even the machines they produce for space are smart too, only humans being are idiot. Do not be deceived by their enthusiasm, as they are children of Hollywood. They take our money as tax and selling for us these CGI pictures and 3D and you believe them. This machine (Perseverance Rover) have 25 cameras and they give us two unclear pictures and all the others pictures are CGI pictures. Do you know that producing CGI video is too difficult rather than take real pictures, why they spent all this time to produce CGI video rather than taking a real video for Earth or Mars. The answer is NASA knew that their world is not true, if NASA give you the real picture you will discover their deceive. Start to believe. They used their deceive for stealing our money, life, and hope NASA used words like "Scientists estimate" to deceive us Use your feeling, Earth is flat

      @Sun and Moon Ehm... The purpose of the Hubble is to take images of far away objets, so why would they use it to take pictures of Earth? Even so, in the past the Hubble has indeed looked back at the Earth for calibration purposes. There are a ton a observation satellites with much better conditions taking images of the Earth at all times (weather satellites most of them). About the images and videos being "photoshop"... Well, prove it. There is nothing wrong with the images being composites, as the Hubble is capable of seeing light beyond your eyes capabilities. But looks like you think that makes the images fake, computer generated right? Prove that please, if you are able (you'll be the first if you can, btw).

    I can't wait to see those pictures from Titan!! I didn't know about RTG's, so it was great to learn about that. I know it isn't nuclear energy exactly, but it does remind me of the old Soviet nuclear-powered trucks.

    Real BS and lies. First the earth is a globe, now they claim it's Pear shaped, and still show us a globe. Then the earth is a closed system and nowhere to go.( The first truth they've given us, firmament) bit they somehow keep sending stuff out to Mars and takes of going to the moon again. Why do people still fall for this garbage? 19 billion in tax payer money, for lies and deception. Karma is coming for these liars and all will be revealed soon. SMH

      How soon? Tomorrow? Next year? Surely corona is also caused by 5G, right? And yes... The Earth is a globe, and yes... It's pear shaped (very subtle, you wouldn't notice) and no... It's not closed. Stop mine quoting to support your paranoia.

    SpaceX has Raptor a methane engine, seems like a methane engine would be a good solution.

      You'd still need oxygen to burn the methane with, and rocket engines aren't as reliable as electric motors.

    THE CHILD WHO UNDERSTOOD GRAVITY Her name was Sarah, Sarah N. Dipity. As a child Sarah often overheard her parents, who were scientists, discuss gravity. They'd often bring Sarah to their office, where they did experiments about gravity and discuss them with other teachers and scientists. They assumed that she wasn't able to understand them, but in fact Sarah understood more than they did. It was frustrating that she was too young to talk. All of them said they didn't really understand gravity, which was why they were doing all that work. Somehow Sarah DID understand. She watched them try their experiments, draw on blackboards, and discuss things well past supper. Sarah realized, like them perhaps, that if someone could describe what she knew that it would be helpful. But she also couldn't write. She watched the adults head off in so many wrong directions. She worried that they'd try to teach her incorrectly, insisting that she learn their ways, which were often wrong. So, Sarah decided not to speak or write, which caused her parents to think that she was slow. She was perfectly pleasant, just silent. In her mind she continued to do thought experiments, using her knowledge of gravity. (c) 2016, Scott Myers all writes preserved

      @Zeen Daniels okay but what is the name of our moon?

      @Rupesh Kumar Sahu No. Moon is its proper name. The other satellites are called "moons" because prior to 1600-ish no other natural satellites were known, so they just called them "moons" because our own Moon (the same happened when DuPont registered the trademark "Teflon". Now a lot of people say teflon to refer to any pan with anti-adherent)

    IIRC, I’ve heard it said that because of the low gravity and thick atmosphere, if a human had something like a space suit with something like wings attached on Titan’s surface, a human could flap the wings and fly like a bird, or something like that.
