Hayabusa2 Now
- doitLP 8y agoThis is awesome. One change I would make is click once on something to launch its description, click anywhere to close. Then the screen is free to select the next description on another item. Otherwise super cool! Anyone know how long the signal delay is?
- GlenTheMachine 8y agoTime-of-flight to Ryugu right now is just under 16 minutes.
- everyone 8y agoI would also remove the dotty background, it makes it less easy to read imo.
- pier25 8y agoIt says on top when the data was generated and received back on Earth.
- gtirloni 8y agoCommunication with Hayabusa2 is via radio waves that are transmitted and received by large antenna at ground stations on Earth. Our website “Haya2NOW” shows these communications in real time. http://www.hayabusa2.jaxa.jp/topics/20180515_e/ http://www.hayabusa2.jaxa.jp/topics/20180515_e/

- andreygrehov 8y agoWhat am I looking at?

- ehsankia 8y agoI'm assuming live telemetry from a satellite. The part I was curious about is, in the message emulator, sending the message seems to take a really long time for a round trip. So it looks like it must be pretty far away from Earth. Little search shows that that it's a probe sent to an asteroid to collect samples and bring them back to Earth. It was sent in 2014, arrived this year, and will fly back in 2019 and arrive in 2020. EDIT: Looks like it just landed on the asteroid, hence this being posted [0] [0] https://www.space.com/41912-japanese-hopping-rovers-land-on-asteroid.html https://www.space.com/41912-japanese-hopping-rovers-land-on-...

- winslow 8y agoAppears to be communications from an asteroid probe to grab samples and return those samples to earth. [1] [1] https://en.wikipedia.org/wiki/Hayabusa2 https://en.wikipedia.org/wiki/Hayabusa2
- sneak 8y agoI am definitely reusing this css for something cool in the future.
- dev_dull 8y ago> Bus power consumption: 600w Sad to think my hacker news machine (PC) is using more power than an an intergalactic satellite.
- fermienrico 8y agoThis is an absurd observation. Why is that surprising given that the satellite is in space and you have a giant powerplant connected to your PC and powering thousands of things in your city? More specifically, why is it saddening?
- craftyguy 8y agoProbably because they think the satellite is more capable of doing cool things than their PC, which is just displaying HN and (presumably) nothing more for them.
- ptman 8y agois it really "between galaxies"?
- craftyguy 8y agoNo. It'll never leave the Solar System unless it happens to surpass the escape velocity of the Solar System. Then, it'll never leave the galaxy unless it surpasses the Milky Way's escape velocity. That would require a tremendous amount of energy. IIRC the Milky Way's orbital escape velocity is something between 300-500km/s (depending on whether you leave the Solar System in a way to take advantage of its forward velocity through the Milky Way or not..)
- bagels 8y agoI don't think large amounts of force is what you mean here, but energy instead. You can escape the galaxy if you apply a very small force over a very long time, or a larger force over a shorter time.
- jaysonelliot 8y agoMonochromatic interfaces can be so beautiful. I'd love to use a modern GUI that adopted this aesthetic. Even though the content of documents would be in color, having the UI itself restrained to a simple monochrome palette would be very enjoyable to use.
- aaaaaaaaaab 8y agomacOS graphite?
- kh_hk 8y agofluxbox, awesome or any other tiling windows manager plus conky can be very near to this interface. Of course, that's just the windowing system and not the GUI itself.
- coldtea 8y agomacOS toned down most ole Aqua UI colors to get there. With the current black theme and a gray highlight it's not that far.
- neoteo 8y agomacOS: Preferences-> Accessibility -> Display -> Use grayscale
- sizzzzlerz 8y agoI didn't know that could be done. I've never even opened up the Accessibility panel. Actually, grayscale is not too bad. Everything is sharp and the contrast is high. However, I think I'll keep things in color anyway.
- aasasd 8y agoAlas, third-party apps—and of course websites—aren't made to be converted to grayscale. This can be easily seen by comparing custom-made monochrome icons in the menu bar to grayed icons in the dock and third-party toolbars (e.g. browser addons).

- fermienrico 8y agoThese kinds of GUIs bother me so much. While they're bedazzling to look at, say in a sci-fi movie, they are horrendously designed in terms of functionality, user experience and ability to convey clearly/concisely with the least amount of ambiguity. It bothers me that people are drawn to it like flies and you see this type of thing everywhere in "Futuristic" projections of our life. They're objectively worse, yet they look cool and the general public values "Coolness" over GUI's ability to meet its core purpose - that is to leverage human vision's bandwidth to convey information rapidly, concisely and without ambiguity. That is the whole point of a GUI.
- jacobush 8y agoKind of agree - however, if the interface elements never move around and stay the same, it's very similar a UX to the instrument panels of old. I.e. not that bad, if precaution is taken against information overload in some kind if crisis.
- fermienrico 8y agoI could write a long essay criticizing the obvious drawbacks of this type of implementation. For example, contrast is non-existent. There is just so much stuff that's wrong, I am overwhelmed as I respond.
- zepolen 8y agoYou're completely correct, but the only way people will understand how bad the UI is if they were forced to use it in their daily.
- jacobush 8y agoExactly the opposite might be true - if you used it daily you would be accustomed to where the critical data is and what it looks like. (Ignoring things which are unknown to us - for instance would the operator benefit from trends in data? This does not seem to be present in the UX.)
- Keloo 8y agoAm I the only one who thought about motorcycle?
- jpavlick 8y agoI did.
- lkuty 8y agoI did too :-)
- spartas 8y agoThere are literally dozens of us!
- Keloo 8y agoThx god
- deleted 8y ago[deleted]
- epalm 8y agoI did too ;)
- sigzero 8y agoNope, I got all excited and was "Awwwww darn it!".
- Keloo 8y agoSame as me. I was like: "Wat the f*, I should check it!!" 2 minutes later... mmmm.....
- catchmeifyoucan 8y agoSame!
- exikyut 8y ago
- sidcool 8y agoThis is amazing. What's the risk that the probe would be thrown out into space when jumping over a bump due to extremely feeble gravity of Ryugu.
- greglindahl 8y agoThe "jumps" are intended to be gentle enough that they won't leave Ryugu's gravity well. For that, you just need to know Ryugu's mass; they had a good guess of that before the mission started, and a much better idea of it now.
- swazzy 8y agoIn case anyone wants to create a realtime 3d simulator: http://haya2now.jp/data/data.json http://haya2now.jp/data/data.json
- happyent 8y agoPass javascript unixtime as url Parameter and you get data over time as well
- loopycode 8y agoI thought it was a new gen bike
- sscarduzio 8y agoAm I the only one that clicked expecting to see a motorbike?
- iamspoilt 8y agoDefinitely not!
- Kankuro 8y agoI expected a train
- posterboy 8y agoI expected an elite FTP server
- starpilot 8y agoI expected a ninja running through a city...
- bartread 8y agoNo, and I was slightly disappointed, but that passed quickly because space vehicles are cool too.
- nkg 8y agoMe too!
- jordache 8y agoyep.. only hayabusa in popular western culture is the motorcycle with the same name
- emcrazyone 8y agofunny that they have power down to the milli-watt and it's so stable. Anyone know what the update rate is? Is it with every second? Cool looking web site

- sizzzzlerz 8y agoI was looking at the rise and set times for each ground station, looking to see which one would take over once the spacecraft dropped out of view of Goldstone. I noticed that each one shows local time, not GMT. Without looking it up, I have no idea which zone these various places are in so I find that display quite confusing. I hope the spacecraft controller's display isn't like that.
- bronson 8y ago> ... so I find that display quite confusing. I hope the spacecraft controller's display isn't like that. Why? You're assuming you have a similar amount of training/experience as the controller?
- nothrabannosir 8y agoI understand the sentiment, but the format of this reply is dangerous. It leads to a spiral of negativity and personal attacks. "Two wrongs don't make a right" and all that. If possible, I'd like to request the assumption of good faith. Hey, at the end of the day, maybe they do know what they're talking about, no? :) Could be an ex Japanese astronaut!
- spockz 8y agoEven if the controller has more training, if he has to do mental calculations instead of reading directly from the screen there will be more chance for errors to occur and it will put a higher cognitive load on the controller.
- yebyen 8y agoDoes he really have to do a lot of mental calculations, or does he just have to remember that "the satellite as it is currently positioned comes into view of my friend Bob's observatory in Canberra an hour and 15 before he goes home for the day, at 3:45PM local time... and with the way we are moving in relation to each other, it has been coming into view approximately 36 seconds earlier each day that passes."
- tluyben2 8y agoIn the bottom it says “Deep Space Center”. What would be the definition of deep space, considering we are no where close to doing anything with deep space for my definition besides observing it.
- GlenTheMachine 8y agoIn this context, deep space is anything not in earth orbit. JPL, for instance, runs the Deep Space Network, which is used to communicate with the Mars rovers, spacecraft orbiting Jupiter, etc. as opposed to the NASA TDRS network which is used to communicate with earth-orbiting satellites. There are various, competing technical definitions of “deep space” — the ITU defines it as more than 2 million kilometers from earth — but the Deep Space Network, and similar networks operated by other countries, are typically used to communicate with interplanetary spacecraft, and are effective basically anywhere higher than geosynchronous orbit (26,000 miles/42,000 km).
- unsignedint 8y agoSome of those earth based stations shown are Deep Space Network stations. You can see status of Deep Space Network at DSN now[0], too. [0]: https://eyes.nasa.gov/dsn/ https://eyes.nasa.gov/dsn/

- dang 8y agoIt can be pretty random what gets traction on HN. That's why we explicitly allow a few reposts (see https://news.ycombinator.com/newsfaq.html https://news.ycombinator.com/newsfaq.html) and why we do things like the second-chance pool (https://news.ycombinator.com/item?id=11662380 https://news.ycombinator.com/item?id=11662380). Eventually we want to add some kind of karma sharing so earlier submitters don't get left out when a later submission takes off. In the meantime, though, it evens out in the long run, so please keep posting good stories!
