  1. Got my EDL shirt!  24 days to go!

      Spiffy! You're all official and stuff. :P

  2. Got a new Mars 2020 baseball cap from the company store.  My Mars Science Laboratory cap is so old it is coming apart.  I've been wearing my MSL cap pretty much daily since launch in 2011 and I really needed a new one.  Not sure I'm a fan of the 2020 patch tho.  Too abstract.  If I didn't already know what it was I probably would never figure it out.  It isn't bad-looking however, and it does have "MARS 2020" embroidered on the side.  Feels secure on my egghead too, which is a big plus all by itself.  :)  I've got a DAWN and an InSight cap that I don't wear much because they're always blowing off in the wind.

  3. RIP the NASA Kepler probe.  Kepler found 2,681 planets beyond our solar system.  Thanks to Kepler we now know that there are more planets than stars, at least in our part of the universe.

      I just heard the same news. Losing Hubble and lost Kepler =/ we need to fund our space programs!

      Probably going to lose DAWN here pretty soon too.  They're almost out of attitude-control fuel.

      But TESS is already up.  TESS was originally planned as a follow-on to Kepler, but since Kepler lasted so long TESS has already launched and started sending us data.  (LOTS of data!  Its highest data rate is 125Mbits/sec, the highest data rate NASA has used to date for any of its probes.  The first downlink the spacecraft dumped over 50GB on us here in the DSN in just over an hour!)

      After TESS there's already the James Webb Space Telescope being worked on.  They haven't launched yet though.  There will also be a lot of competition for viewing time on JWST since it isn't only a planet-finder.

  4. FWIW, Kerbal Space Program and the Making History DLC are on sale at the Steam Store.  60% off of KSP itself and 33% off the DLC.  For the next 2 days $25US will get you both...

    (I'm not in any way connected to Steam, Valve, Take Two, or Squad.  I just have a blast playing the game.)

  5. How many planets are there in the solar system?  8, right?  Used to be 9, but Pluto got demoted to "dwarf".

    Ok, so if you add Pluto and all the other "dwarf" planets back -  Ceres, Eris, Makemake, Orcus, Salacia, Haumea, etc - how many known planets are there in our solar system?  A couple dozen?  A hundred?  A couple hundred?  There's an astronomer at CalTech who's been looking into the matter & he's been keeping a "little" list...

    http://web.gps.caltech.edu/~mbrown/dps.html#table

    For what it's worth, a (dwarf) planet only 470km in diameter has a surface area the size of the (US) state of Texas.  Something the size of the entire country of Japan would be about 350km in diameter.

    That's a lot of real estate.

    And that's just what we know about.

      Interesting, though I wish he provided a legend to read this stuff. He only provides 5 categories, but there are more than 5 colors it seems.

    2. Wedgy

      While it's interesting as all heck, this tidbit really irked me:

      10 objects which are nearly certainly dwarf planets,
      26 objects which are highly likely to be dwarf planets,
      64 objects which are likely to be dwarf planets,
      127 objects which are probably dwarf planets, and
      661 objects which are possibly dwarf planets. 

      I'm sure there's some scientifically backed reason there are five categories, but using words that are so blatantly synonymous to classify them is extremely confusing. "Possibly," "probably," and "likely," all mean the same thing. In my mind that lumps them all into the same category.

    3. efaardvark

      efaardvark

      The text just above the table defines how the terms are applied.  The problem is that it is REALLY hard to even see these things, never mind determine their size.  There is so little light that even Hubble has trouble seeing them.  Basically you have to be looking at a star and notice that it disappears for a while.  That tells you that /something/ was there, and gives you a lower limit on the size.  (If you know approximately how far away it is then that gives you a read on the speed that it is travelling in orbit around the sun.  Based on that speed and the duration of the occultation you can determine that it has to be a certain size or larger.)  To be a "dwarf" planet, it has to be round.  Unfortunately, the composition determines how big a body can be before it becomes round.  How do you determine the composition of a particular body when you can't go there and can't even SEE it properly?  How do you know the size when the occultation time might be through the thickest part of an irregular object or might barely nick the edge of a larger round body?  Some of these things, like Haumea (spins so fast it is oblong, has two moons and a ring orbiting it), are really strange and hard to get a handle on.

      You can figure things based on what you know, and you can put limits on what might be, what can't be, etc., but the error bars are pretty large.

      How many dwarf planets are there? Ceres is the only asteroid that is known to be round. After that it gets complicated. All of the rest of the new dwarf planets are in the distant region of the Kuiper belt, where we can't actually see them well enough to know for sure if they are round or not.

      While we can't see most of the objects in the Kuiper belt well enough to determine whether they are round or not, we can estimate how big an object has to be before it becomes round and therefore how many objects in the Kuiper belt are likely round. In the asteroid belt Ceres, with a diameter of 900 km, is the only object large enough to be round, so somewhere around 900 km is a good cutoff for rocky bodies like asteroids. Most Kuiper belt objects have a lot of ice in their interiors, though. Ice is not as hard as rock, so it less easily withstands the force of gravity, and it takes less force to make an ice ball round. The best estimate for how big an icy body needs to be to become round comes from looking at icy satellites of the giant planets. The smallest body that is generally round is Saturn's satellite Mimas, which has a diameter of about 400 km. Several satellites which have diameters around 200 km are not round. So somewhere between 200 and 400 km an icy body becomes round. Objects with more ice will become round at smaller sizes while those with less rock might be bigger. We will take 400 km as a reasonable lower limit and assume that anything larger than 400 km in the Kuiper belt is round, and thus a dwarf planet.

      How many objects do we know in the Kuiper belt that are 400 km or larger? That question is harder to answer, because we don't actually know how big most of the objects in the Kuiper belt are. While we can see how bright there are, we don't know if they are bright because they are larger or are highly reflective. In the past, we had to just throw our hands up in the air and say we don't know enough to even make reasonable guesses. But in the past few years, systematic measurements of the sizes of objects from the Spitzer Space Telescope and now the Herschel Space Telescope have taught us enought that we can make some reasonable estimates of how reflective objects are. (It's complicated: read the details here ) These reasonable estimates, combined with all available actually measurements, give us the list of the largest Kuiper belt objects, sorted by diameter, below. Carefully note the lack of any error bars. Every single measurement or estimate below is uncertain to some extent or another. I don't include the individual uncertainties in the table, but instead use the ensemble uncertainties to inform classification below. In other words: take the sizes of specific objects with bigger or smaller grains of salt.

       

       

  6. Wasted a weekend, but I got my car! 

    20181020_PriusPrime.thumb.jpg.36e7355201cf6a9d0b269d651c6d887e.jpg

    I must say, this was something of an experience.  I don't buy cars often.  I treat them well and tend to keep them until they die naturally or are murdered.  My last car was an '07 model that a tree fell on.  The one before that I think I bought sometime in the mid 80s.  I haven't been in the market for over a decade.  These days cars seem a bit different.  Much more exposed electronics and gadgetry.   In fact, these days they're more like "smart" phones.  For example, ipad-like touch consoles seem all the rage (whether you like them or not).  You also tend to have to charge them overnight before you can really use them.  :D  The dealerships I visited were all pushing either hybrids or EVs, or at least things claiming to be hybrids or EVs.  (Is a double-sized battery and a larger starter motor /really/ a hybrid, even if it shuts off the engine at stop lights?  I have my doubts.)  And the apps!  Why apps on your car when texting and cellphones are already such a problem?  Really.  Bad.  Idea.

    One thing that hasn't changed however.. that new-car smell.  :)

    1. efaardvark

      efaardvark

      Yeah, BT is a Good Thing.  For cellphones, well, I'm one of the 0.01% of the population that will actually turn off their cell connection when driving.  What calling I do is usually just 30-second "I'll be late" type notices when stuck in traffic.  Though I don't use it much, for those times hands-free calling is wonderful.  I also had a bluetooth gadget for wirelessly connecting my phone to my old car's "aux" audio input for spotify because I literally wore out my last phone's audio jack plugging/unplugging for the commute.  (I don't buy new phones very often either.)  I made sure this car had both hands-free phone and BT audio input built-in.

    2. brycec

      brycec

      Most of the time, the apps stink, so it is a bad idea in that respect, but I still think they could be neat, especially if it could make the car invisible.

      Nice looking car though.

    3. efaardvark

      efaardvark

      I wasn't impressed with the apps I saw either.  The apps I want/need are already on my phone for the most part, and I don't need the distraction of dealing with any of the ones in my car while I'm driving.  The only apps I use with any regularity while actually driving are waze and spotify anyway.  I'll probably use the built-in GPS instead of waze because the car's display is bigger.  It would have been nice to have spotify built-in too, but with the BT connection that's not a big deal.  The car does have Sirius XM and Pandora.  XM I'll probably use for the 3 month trial and not miss it afterwards.  I have yet to try Pandora, even though I have a subscription.  That might be good enough to replace spotify when I'm in the car.  Other than that the rest is uninteresting at best, and distracting at worst.

      Invisibility would be cool.  Dangerous, but cool.  :)

  7. Pretty windy here today.  Beware low-flying trees, and parts thereof...

      Bummer. U,u Hopefully the payout is still good enough to make it less painful.

  8. So now we have a new chiweenie "dog" - aka Mexican hotdog, aka German taco - in our household.  (Chihuahua/Dachshund mix.)  Cute as heck, and good lap dog for my 80yo mom, but I'd have liked a real dog.  Preferably a pit (like our last), or at least a beagle or boxer.  Something I could take hiking anyway.  This would just be bait for the coyotes and mountain lions, even the hawks.  4 billion years to create wolves, and then humans came along and did this.   smh  :D 

    1. efaardvark

      efaardvark

      Our last dog never really got the hang of swimming either.  She liked getting wet, and she would do a sort of log-ride splash thing where she'd run full-tilt into the water and splash everything/everyone nearby, but she didn't like paddling around at all.  If her feet couldn't touch the bottom she'd freak and try to get out of the water.

       

      This is what a chiweenie looks like:

      8 weeks old so still a bit of growing to do, but not going to get too much bigger.

  10. Thinking about building a new budget game box for my brother's steam/etc. activities (his old one has been taken over by his GF. :D )

      @Roxeg He is talking about a gaming PC.

    2. efaardvark

      efaardvark

      A game box in this case is a computer to (mostly) play games.  On "his" old computer he mostly played minecraft, WoW, and Civilization.  Occasionally he'd get on his steam account and download something else to play for a while, but those are/were his main go-to games.  Something that could run those reasonably well, plus do stuff like email, web, etc.   His old system was an i3 with 4G ram and a Radeon RX460 w/2GB.

  15. My new air conditioner came!  Now maybe I'll be able to sleep at night.

  16. Not exactly full-spec Nerve Gear, though that's probably for the best all things considered.

    BTW, I think the techs should have removed the log out option, just for giggles.  :D

    As a PR campaign, JAXA allowed people to submit names and messages to be printed on plates to be placed on the Akatsuki probe. The submissions consisted of hundreds of thousands of names and messages, all encouraging the craft on its mission. Printing these names and messages on about 90 aluminum plates, they loaded them onboard and launched the probe into space. Of these 90 plates, three of them consisted of images of the Japanese AI musician Vocaloid Hatsune Miku (as well as her weird, squished persona Hachune Miku) — sending the pop-culture figure on a long voyage into space.

    Gotta love the Japanese pop culture.  :)

      Nice share. The video was pretty interesting, but I feel like the guy could have made it longer. I so wanted to see an anti-tank round being used against an asteroid, because of what was said at the end.

      If  the drones work as expected there will be video from the impact.  はやぶさ2 is an interesting mission.  Kind of Deep Impact, Rosetta, and Dawn all rolled into one, but on a budget.  It is a cool mission.

  19. "Your Ubuntu 17.10 is up to date, but there's a newer version 18.04.  Would you like to upgrade?"

    It seemed so innocuous, so easy.  6.5 hours and a clean install later I'm basically back to where I started, though with working HDMI sound (and a LVM layer underneath it all so I can make a snapshot before clicking that "ok" button.)  GPU stuff seems a little snappier too, though I haven't actually done any benchmarks.

  21. TFW you realize that you have browser tabs open for both the Mycroft project page and the GLaDOS wikipedia entry.  😱

  22. Anyone going to the JPL open house this weekend?  If so, it looks like it is going to be a sunny day!  Good weather is nice, but it also means it'll likely be hot as well.  There will be water and shade, but also queues outside the popular venues, so bring your patience as well as your ticket.  Hope you have fun!

      This is the Jet Propulsion Laboratory's open house in Pasadena, California that we do every year.  It is a local thing for the most part, though we do get a few people coming in from out of state as well.  It is extremely popular, especially with the kids, so crowd control is an issue.  A few years ago attendance got up to over 40,000 for the weekend.  It was hot that year too, with temperatures over 100F.  We had to start issuing tickets to the event to limit the number of visitors as a safety measure.  (Tickets are free, but limited in number.)

      Sounds like a lot of fun. Wish I could attend. It's just very far away. :(

  23. Just went and got a nice wireless headset for use during those late-night gaming sessions.  Apparently rockets make too much noise when they explode for people trying to sleep nearby.  Who knew?  :D 

    This replaces my old wired one that was really more call-center quality on the sound, and physically falling apart besides.  (My policy is to buy a new headset every decade whether I need to or not.)

    Going to make the rounds on my discord list to test it this weekend.  (Which starts in 2 hours, 10 minutes.. not that I'm keeping track or anything. ;) )

      that's why ive never got in to it !

      ima slow at typing

      I use a projector but have trouble reading the chat whilst playing !

      and being I use a projector , I play in the dark so utilising the keyboard is even more fun ! even just for this :P 

      but with this set up movies and mmos visuals are great

    2. Wedgy

      To each their own, I just like talking with people too. Heck I'm in VC right now lol I've always wanted a projector setup but I never had the right amount of space available.

      I just never knew how to set up VC or what I needed so that's more why I didn't get in to it

      but I can see it be so much easier to have in parties playing mmos whilst concentrating on what your doing , unfortunately this oldtaku just never got round to figuring that side all out . bit prob should

      oh and whilst reading and replying to this I did look up the Logitech G933 and I can go get it for $199aud

      not that id know if that's good or not

      but im also refinancing my house atm and thinking ill get a little more this time and smart wire it (and my shed) with voice as well and may be get the VR ive also wanted
