Groundhog Day at NASA-Ames: Episode 1, The State of NASA

At Ames: “The Big White Dome”

This is my second “NASA Social”, part of a new(ish) PR program at NASA which is (successfully, I should add), linking the venerable government institution with this modern social-media-dominated universe. At Ames Research Center, which just celebrated its 75th birthday, I even qualify as “younger generation.” That alone is worth the price of admission. Last time, I stayed in the Facebook & Twitter world; this time I worked on my photos & videos for the blog.  While I may not tweet as rapidly as those youngsters sporting Google Glass, I hope I’m bringing a relatively-informed viewpoint to the show along with my fangirl attude.

Yeah, I know. I have my own engineering Ph.D., but I’m still a fangirl when it comes to space stuff, science stuff, and robot stuff.  And the best place to find all that stuff is still NASA.

OK, so, I’m expecting this one to be relatively dull, as the thrilling event of the day is The State of NASA (insert non-martial fanfare here) address being livestreamed from Kennedy on the big screen at the Ames Exploration Center. The last-minute info email the Ames team sent out last night hints at more than that: a “preview” of the ATV-5 re-entry, a “tour” of the Roverscape (a dirt lot with rocks in it), and (oh, joy) all about the new budget proposal.

Waiting for the livestream from Kennedy Center to get under way, it becomes clear we’re really just watching NASA TV, only without access to the DirecTV remote. There’s a very brief, flashy video of inspiring fun NASA images: think ooh! ahh! all accompanied by the voice of the lovely Peter Cullen (aka Optimus Prime). But then NASA TV switches to their familiar old-style rolling globe image with a static “coming next” title. No sound, just a slide. Not something that would get a channel-skipper to pause and watch. A teasing view of the crowd jostling for seating and the Director finding his spot in front of Orion would be more engaging. Maybe they could bring in an intern from a college media studies program to keep viewer interest up when there’s a little delay in an event startup.

Meanwhile, here’s a party game: What did you recognize in that rapid-fire video with Optimus Prime narrating? Here’s my list:

The View from Ames

The View from Ames

Well, you can watch the State O’ NASA message yourself on YouTube, to get the full effect. It’s only a half-hour, plus that four-minute preview video featuring brief glimpses of the work NASA is doing, with Real Scientists and Engineers. And robots. And Astronauts. Run it in the background while you’re updating your Facebook. Make the kids watch the preview, maybe inspire them to consider training to work at NASA someday.

What you get here is a few my own off-the-cuff reactions and observations.

No surprise, The Journey To Mars is still a core theme. If you’re down on manned spaceflight, one thing I’m noticing is that there is a heck of a lot of science being packed into these projects. It’s almost as if the popularity of the notion of sending human beings to Mars is being leveraged to get more actual discovery accomplished. Hmmmm. As always, at least since Apollo ended, NASA’s a shoestring operation, and it’s rather astonishing just how many things are going on under that big umbrella.

If you haven’t been paying attention, you might not know that our current NASA Fearless Leader is a former astronaut, Charles Bolden. He flew on four Shuttle missions between 1986 and 1994, so he was part of NASA for Reagan, G.H.W. Bush, and Clinton. Ten years after Bolden had left the astronaut business to go back to his first career (the U.S. Marine Corps), G.(noH.)W. Bush got so inspired by the success of the Spirit and Opportunity Mars rovers that he decided NASA’s new mission should be to get people back to the moon and on to Mars. And just five years after that, Obama put Bolden in charge of that mission, as well as the rest of the tasks NASA manages with a budget equal to about 3% the size of the defense budget.

The fun part of the State of NASA speech was not the words, because they were pretty much what you’d expect: upbeat, replete with “Reach for New Heights” inspirational affirmations. The fun part was the setting: they talked the engineers who’d been happily disassembling the Orion capsule to put it back together, and Bolden gave his talk in front of the blackened shell of the successful first trial of NASA’s new system designed to carry humans into space…even to Mars. To add flavor to the show, the organizers commandeered a space large enough for not one but three future human vehicles. There was a SpaceX Dragon C2+ capsule

showing off its innovative weld-free design structure.

Oh, and there were lots more people at Kennedy than we had at Ames. But at Ames, front-row seats were very accessible and anyone wanting to spread out over several seats was just fine.

Just as I notice a poster peering out from the edge of the Orion capsule, with logos and addresses for all NASA’s social-media connections, the feed goes down. The smartphones rotate 90 degrees and are all searching for the livestream. OK, it’s not just Ames, it’s NASA TV. But, really. Hire that intern, guys.

Well, it’s up again within a few minutes, though the audio is sketchy for a bit. What do interns get paid? Like, minimum wage, right?

So here are the highlights picked up in between tweets:

  • The Asteroid Redirect Mission (ARM) gets first mention in the context of pathway to Mars—though we still haven’t decided if the plan is to capture a whole small asteroid or to extract a chunk from a larger asteroid.
  • A glimpse of the budget comes next…there’s a bump-up of $500 million for fiscal 2016, though who knows what Congress will do with the budget request. Keep in mind that NASA’s proposed $18.5 billion is about 3% of the proposed defense budget and about 0.04% of the overall budget. How NASA can do this much with peanuts is amazing. Oh, wait. Suddenly I understand the peanuts ritual at JPL launch & landing events.
  • There’s a return to the Mars topic with shout-outs to all our Mars explorer robots, including a total brag on the U.S. having the first and (so far) only Mars landers. (OK, yes, we still love our friends at ESA, who landed on a comet.)
  • Then we get a reminder of the brilliant science from our telescope projects
    Hubble Reveals the Butterfly Nebula

    from Hubble (which Bolden helped launch) to Kepler to James Webb. Even Chandra, which does superb work in the X-Ray spectrum, gets a mention this time. And the Solar Dynamics Observatory scores a slot in the closing segment.

    Chandra X-Rays the Universe

  • The Shuttle program is over, but it still makes it into the talk. Keep in mind Bolden is a shuttle veteran but also remember that, like his boss, he’s the first African-American to hold his job. Bolden flags the Shuttle program as the one that brought diversity to NASA, since it finally opened up space to women, minorities, and others who previously “wouldn’t have a chance to fly”. That is the thing he tells us to view as the crucial long-term legacy of the shuttle program. (Side note: Bolden’s Deputy Administrator for 2009-2013 was the first woman to hold that position, Lori Garver.)
  • There’s a reminder that the money spent on space is money spent in the U.S., from small business to large ones, from textile mills to welding shops. And the cash gets shared out, with 37 states having a stake in the commercial crew mission.
  • Education gets a nod, though to be honest I’m a little disappointed that what gets the splash are the student science program at ISS and the flight of a student project on the Orion test flight. Those big projects still tend to end up at private and/or privileged schools, since it takes resources to play. I might have gone for a specific shout-out to one of the schools for which participation was a big leap, like Oakland’s Urban Promise Academy.  Still, if there’s a kid doing a science report who hasn’t logged into a NASA website, then that kid doesn’t have internet access.
  • All right, then we get a round of teasers on upcoming technological developments: “green” (less-polluting) propellants, advanced autonomous robotics, high-power solar electric propulsion, aviation advancements.
  • NASA’s moving forward in its ongoing role in earth and climate science. We’ve got that successful launch of the SMAP climate science satellite (http://smap.jpl.nasa.gov/), just a week ago, which has both direct practical applications for agriculture. And the Airborne Snow Observatory has already produced data to help with the drought in the West, especially California, where snowpack is key to water supplies.
  • True to the core message, the closing draws focus back to Mars, promising a geophysics mission with the InSight lander scheduled to launch in March of next year.   And a taste of special features planned for the Mars 2020  successor to Curiosity, including a way to shoot a sample back home to Earth.
The Core Message

The Core Message

 

One last item in the dark hall of the Exploration Center: we get to watch a video from the re-entry of ESA’s ATV-1.  Kinda cool, but old-school, dating back to 2008. But this is just a teaser, for the upcoming re-entry of ATV-5. Here we’re working at the opposite end of the scale from Orion and Dragon, where the concern is careful braking and heat-shield materials and safe landings. These re-entries are in the realm of Design for Demise, in which hardware at the end of its life is sent down to burn up in Earth’s atmosphere. It’s not as simple as it might seem, when your goal is to NOT have bits of debris landing on the surface. I snipped together my video of their video to make a one-minute infomercial for ATV-5. Well, one does what one can:

There are two instrument packages onboard ready to monitor descent. ESA’s contribution is a video camera (wow!) while NASA’s package records acoustic data, temperatures, deceleration info and more. ESA's Camera Setup for ATV-5Both will “phone in” their results using the Iridium satellite network. Yep, ESA and NASA will be totally outclassing everyone else’s phone video uploads that day.  (ESA’s page is complete with a countdown clock. The twitter tag will be #bigdive.)

Lessons of a BayCon Gofer: There Is No DogLessons of a BayCon Gofer: There Is No Dog

The final day of a convention can be a downer: games are ending, there are no parties pending, the con suite is running short on the good stuff, some people you just got to know are leaving early, and—not the least of it—you’re really, really tired.

The Signs Are On the Wall

The Signs Are Coming Off The Walls, Now

I wasn’t due for “work” until afternoon, but I roused myself earlier, for the last DIY project—Make A Parasol (see Firefly).   Alas, I’d missed a program schedule update & the project was over. Long over—it had happened the day before! Won’t happen this year—I’ve finally joined the Smartphone Universe & so have access to the online schedule for BayCon 2015.

 

There's Planets Around Them Thar Stars

There’s Planets Around Them Thar Stars

I did have a backup plan—a panel discussion on new discoveries about extrasolar planets. But I’m kind of a Kepler fanatic, so the information being shared was, well, old hat. I found myself nodding off while people were talking about one of my favorite subjects.

So off to the Gofer Hole to check in and claim my spot as the Art Show Gofer. The day wasn’t boring any more.

My Final Badge-Ribbon Collection, Nowhere Near Championship Length

My Final Badge-Ribbon Set, Actually a Relatively Small Collection

I had my chance to be part of the Art Auction. That was cool—I’ve never been, because I can’t afford to bid anything near what auction items should go for. Instead, I got to set up bidder numbers for folks who did have the resources and were eager to support these wonderful artists.

Once the Auction wound down, I got to be on the giving end of the Art Show. That is, folks queued up to collect the pieces they’d won in the silent bidding and—later on—the auction. The staff took care of the official tasks of collecting payments and pacifying people who’d not won the pieces they wanted. As a Gofer, I fetched their purchases (from the stacks we’d so carefully arranged the night before) and saw those their faces light up with happiness.

Eventually, all but a few of the neat stacks were gone. A few winning bidders were late to collect their prizes. But we set those safely aside.

In the meantime, all afternoon, artists were coming by and packing up any pieces that hadn’t sold. We helped if needed—fetching supplies, finding paperwork they needed, taking down labels and hooks from the display boards—and it was cool to get to talk directly with the artists. Several artists had entrusted the convention staff to display the work on their behalf, having shipped the art with their registration forms. Most had a piece or two still unsold, and these needed to be repacked for shipping homeward. The original boxes were not necessarily available, so I made the rounds of the vendor room to scrounge empty boxes.

Gradually, one by one, the display boards were emptied, we collected all the hooks, labels, and trash, and the staff tracked down the last of the tardy winning bidders.

It was time to empty the room. Load-out time. Most of the stuff needing shifted was heavy—pegboards, frames, bins full of papers and supplies. So I called dibs on the job of getting all the art-to-be-shipped-home safely out to the Art Show director’s car. It took a few trips through a lobby full of exhausted attendees and staffers. Then I glommed onto an empty luggage cart. Plus, the Gofer King was one of the staffers in the lobby and he dispatched an idle Gofer to help on my last round. Whew.

So, most of these events end with what they call Dead Dog.   That’s one of the things you hear staffers talking about near the end of a convention, but they don’t share with mere members what exactly that is. The deep dark secret is: it’s a party. It’s the staff party that happens when everything’s over, the attendees have gone, and all the clean-up work that can get done is done. Aha, it’s what theater types call a strike party.

Generally speaking, it’s a Staff event, but Gofers who stick it out all the way to the end are welcomed into the party. There’s food. All the leftovers from the weekend, that no-one wants to have to haul home. All the ice-cold sodas left in the Magic Charity Soda Machine. Meanwhile, the hard-core staffers take the opportunity to give thank-you speeches to each other and praise the folks who’ve stepped up to chair the event next year.

It felt a little like crashing the party at that point, but the Art Show leaders were saying nice things to me, so I felt better. And Alison asked if maybe I’d help her as staff in 2015.  And finally, finally, I gathered up my own art purchases, and Went Home.

 

Art Show Victory!

2015 Art Show Staff!

Gofer Lesson of the Day:  If you stick it out to the end of everything, you can get into the fabulous Dead Dog party.  There will probably not be any dogs there, just tired-out volunteers.  Like you.

How to do this:

Method #1:  Walk into the Gofer Hole and sign up.  You do need to be 16, but there’s no upper limit.  Yes, really, you, too, can be a middle-aged Gofer.  For BayCon 2015, the secret lair is in Tasman.  Go up the escalator, turn right and it’ll be on your right before you reach the convention center.

Method #2:  Email the King of the Gofers.  That’s gofers15@baycon.org.  You get double credit for helping at setup on the day before the convention starts. If you’re super-eager to help & don’t get a reply, email me (cometary@cometarytales.com) and I’ll help you make contact.

The pre-midnight roll-out

One thing about the global economy…it’s January 31st in some places already. Barnes and Noble has the paper editions as well as the Nook version ready to go.

Meanwhile, Amazon is lagging behind, with just the Kindle version and it still is tagged as “preorder” . . . in the U.S. C’mon Jeff, don’t you want more money for your rocketship project? UPDATE: Amazon is up, in Kindle and Trade Paperback editions.

But you can download it from Amazon’s sites for the UK or India.

And it’s up at Canada’s Biggest Bookstore, !ndigo.

And in Australia at Angus & Robertson.

No problems at Smashwords, either.

And you can use Paper Angel as a home base, plus a place to read the sample or order a signed copy direct from the publisher.

My favorite, though, is the listing on Rakuten-Japan. Though of course it’s on “regular” Rakuten, too (i.e., Kobo).

A Top-Down Search for the Strange Charm of Putting Up With Those Quarks at Bottom of the Universe

For part two of our universe-construction project, while the helium models dry, it’s time to delve into the depths of the sub-sub-atomic universe.

Consider those carefully-constructed model atoms.   Each contains protons, neutrons, and electrons.

As it turns out, with electrons, there are (so far as physics can determine at present) no smaller particles needed to build an electron.  Electrons are part of a group of  six elementary particles called leptons.  Some of these leptons–the neutrinos–were predicted to not even have any mass, but experiments have shown that while they are incredibly low-mass, neutrinos do have some mass.  Interestingly, these experiments leading to even more new developments in fundamental physics and the Standard Model theory.  Still, electrons are by far the most numerous leptons (at least in our corner of the multiverse.)

In our candy-based model, we have more than one proton crammed into in a nucleus.  Each of those protons has a positive charge, but we all know that objects with the same charge repel each other.  Why does the nucleus stay together?

In our model, of course, there is all that sticky candy.  But in the real atom, there is also something that, in its own way, makes protons stick together.  These other particles are one type of another class of matter, called mesons.  These strange, essential, particles are stable only inside the nucleus, where (like our sticky marshmallows) they act as a “glue” to hold protons and neutrons close together.

Given that extremely tiny leptons have been observed, as well as tiny mesons inside the nucleus, protons and neutrons may begin to seem too big to be elementary particles.  Sure enough, it turns out that protons and neutrons are also made of smaller particles.  And those mesons, too, are made of those same even-smaller particles.  And, while it took thirty years to search them all out, a total of six more fundamental particles (on top of the six leptons) have been found.  Most of the matter we know about only requires two of those particles–plus the electron–but modern physics predicted six, and sure enough, there are six of them.

Meet the QUARKS.  Their six kinds are: up, down, charm, strange, top, and bottom.  Each kind comes in a matter form and an antimatter form.

Intriguingly, the terminology for “kinds” of quarks is flavors. Other characteristics of quarks and leptons include color, another clue to the pleasure scientists find in these discoveries.   For now, we’ll experiment with the flavors of quarks.  Unlike real quarks, we will use macroscopic objects that also happen to taste sweet.

As usual, if you’re working with youngsters, begin by reassuring everyone that there will be plenty of time to eat their quarks later.  Each person gets one each of the six flavors of candy…quarks. Because the candies will be handled a lot during the first stage, tell them not to open the wrappers yet.   Observe the candies.  One side has the brand name on it, and the other side is plain.  If we put the candy name-side up, we’ll call it a quark, and if it has the plain side up, we’ll call it an antiquark.

Quark vs Antiquark

A meson is formed by pairs of one quark and one antiquark.  Give the group some time to see just how many combinations can be made of such pairs.  (A few special mesons combine two or three such pairs, in quark combinations.)

A Small Set of Mesons

This will take some cooperation–participants will want to get together and different groups will organize their tests differently.  Meanwhile, if you have access to a whiteboard or poster paper, you can sketch out a list of simple mesons shown below.  For smaller (or older) groups, you can also pass out copies of this grid and let everyone check off the combinations as they are discovered.

quark antiquark candy (name) candy (plain)
bottom eta b b pineapple pineapple
Upsilon b b pineapple pineapple
charmed eta c c purple purple
D+ c d purple peppermint
D0 c u purple red
J/Psi c c purple purple
Strange D c s purple green
Charmed B b c purple pineapple

B0 d b peppermint pineapple
Phi s s green green
Strange B s b green pineapple
pion u d red peppermint
kaon+ u s red green
B+ u b red pineapple
Charged rho u d red peppermint
Kaon*+ u s red green

What’s important from this exercise is realizing that all of these two-quark combinations can really happen.  Some of the mesons are the ones that help stick nuclei together.  Others are found in outer space, as cosmic rays.  Others are only found when scientists smash other particles together to find out what they are made of.  Recently, the last of the mesons described by this model was detected by an international team of physicists, using the Large Hadron Collider at CERN, in  Switzerland.  This prompted huge celebrations by physicists and the process inspired a documentary film about the search for the Higgs Boson, Particle Fever.

When I ran this project at BayCon in 2017, one of the young participants scanned the list above and said, “What about the top quark?”  Trust a science-fiction fan to spot an anomaly.  Indeed, none of the known mesons make use of the top quark, which is the most elusive one of all, and in some ways the most peculiar.  The top quark is extremely unstable–even more ephemeral than the strange, charm, and bottom quarks–and it requires a large particle accelerator to observe one. (Fermilab managed it first; now CERN‘s Large Hadron Collider holds the record.)  Even then, once produced, a top quark vanishes in 1/1,000,000,000,000,000,000,000,000th of a second.  The top quark is also amazingly massive, fueling the deep interest in the nature of mass itself, which many think is one of the functions of the Higgs boson, which itself has only recently been (tentatively) observed.  Scientists at CERN hope to use the relatively massive top quark as a test laboratory to verify their (provisional) Higgs boson observations.

Three-quark particles are called baryons–the most common of these are protons and neutrons.  The next step for our own quark exploration is to find the combination of up and down quarks that yields the proton and the one that forms a neutron.   Each person has 2 peppermint and 2 of one other color to play with. Each group can also pool resources (still keeping those candy wrappers on) to mix and match groups of three using only 2 colors of candy.

To sort out which of these combinations works requires one extra piece of information.  We know that an electron has a charge of -1, a proton has a charge of +1, and a neutron is neutral, with a charge of zero.   Another cool feature of quarks…and one of the hardest things their discoverers had to come to terms with…is that they have fractional charges.  Before quarks, everyone used to think of a charge…equal to the electric charge of an electron…as an indivisible thing.  Just like an atom.  But just as it has turned out that atoms aren’t indivisible, neither is charge.

Up quark’s charge:       +2/3

Down quark’s charge:   -1/3

So, with just a little arithmetic, we can find out which of our combinations makes a proton and which makes a neutron.  Here’s the cheat sheet:

uuu

2/3 + 2/3 + 2/3 = 2

Positive…but too much for a proton
ddd

(-1/3) + (-1/3) + (-1/3) = -1

Negative, so it can’t be a proton or a neutron.

Note:  it’s not an electron either–remember, an electron is already an elementary particle.

uud

or udu

or duu

2/3 + 2/3 + (-1/3) = 1

OK!  It’s a proton!
(Just a reminder…the order the quarks are listed in doesn’t matter.)
ddu

or dud

or udd

-1/3 + (-1/3) + 2/3 = 0

Yes!  We have discovered the neutron!

 

Aha, it’s a proton.

Aha, It’s a neutron!

So, the charge calculations show that protons and neutrons are made of two ups plus one down for a proton and two downs plus one up for a neutron.

It’s possible to have participants glue their protons and neutron quark groups together.  A dip on the water cup from the atomic marshmallow project will make a candy piece sticky.  However, these sticky messes will need to sit aside for a while to dry.  If your participants include young children, you might want to skip that possibility, as a glued-up stack of Life-Savers could be a choking hazard.

Speaking of glue, the same BayCon2017 participants also suggested some ideas for incorporating gluons into our model.  To cover the topic of quantum chromodynamics would be a fun challenge, but for the present, those lonely orange LifeSavers we’d set aside as those transient top quarks can be added between the red and white candies in our proton and neutron models to represent the color exchanges among the quarks.

So now we have established that everything in matter is made of tiny (and flavorful) points of dancing energy called quarks and leptons. How can we visualize the true relative sizes of these quarks, protons, nuclei, and atoms?

Poke a pin through a piece of paper and hold it up to the light, then pass it around, so everyone can see how tiny that hole is.   Think of that bright speck as an electron or a quark.  To be at the same scale, our helium nucleus would be about 3 feet across.  A handy meter-stick or yardstick will provide a sense of scale, but for drama, bring out a huge balloon (the 36-inch size).  It won’t be edible, but it will be fun to play with afterwards.  If that big old balloon is the tiny nucleus, then to build a whole helium atom we’d need a marshmallow about seven miles (ten kilometers) across!

So let’s check back on our atom model from the atomic marshmallow project.  It’s mostly nothing, just that airy, fluffy marshmallow.  Remember how thin the “shell” of the electron cloud is, and how surprisingly hard it is to notice the tiny nucleus once the two little protons and neutrons were placed inside.  Even so, in our model, the protons and neutrons are huge compared with the atom.  Imagine how fantastic the resulting candy treat would be–and how many people could enjoy it–if we’d tried to make this marshmallow atom model to scale.
