RapidFood, or: Revenge of the Space Cornbread

Pictured here is my food model of NASA's next Earth science mission, ISS-RapidScat, which will monitor ocean winds from the International Space Station.

By now you’ve probably noticed that one of the ways I celebrate upcoming NASA mission launches is by creating edible food models of NASA satellites and instruments. And then, of course, I eat them. (Check out GPM and OCO-2, both of which launched earlier this year.)

ISS-RapidScat is third in line for this year's Earth Right Now campaign, which centers on five NASA Earth science mission launches occurring over 12 months.

ISS-RapidScat arrived at Kennedy Space Center (in Florida) in May to begin final preparations for its launch at Cape Canaveral. RapidScat and other cargo and instruments will arrive at the International Space Station (ISS) aboard SpaceX's uncrewed Dragon spacecraft on top of a Falcon-9v1.1 rocket. The Dragon will dock on the ISS, and then a mechanical arm will unload the instrument and mount it onto the space station. Ground controllers will operate the mechanical arm.

ISS-RapidScat is a scatterometer, a radar instrument that measures near-surface wind speed and direction over the ocean. Stronger ocean winds create choppy seas with rougher waves that scatter the radar signal, while a calm ocean causes less "backscatter." Scatterometers are used to forecast weather and to monitor hurricanes.

I created this edible model from foods I actually ate, so nothing went to waste. I used homemade cornbread for the ISS attachment; the electronics subsystem is tri-tip; the spin assembly is made of eggplant, a pineapple slice and a carved apple; the antenna is made of grapefruit, sticks from my grapevines and a grape; and the brackets are celery. And yes, I know, it looks kinda weird.

Go ahead: Make your own NASA ISS-RapidScat model and share your photos in the comments section. You can view a spacecraft detail drawing here, and you can learn about the ISS-RapidScat mission and see more illustrations on the mission home page.

I look forward to your comments and creativity.

The struggle to reach out and tell the climate story

Credit: Lightspring / Shutterstock.com

“Nope, no. No. Nuh-uh. These aren’t good.”

I’m sitting next to one of my instructors at the University of Southern California‘s Annenberg School of Journalism where I’m taking a course in multimedia. We’re going through a series of photographs I’d taken for an assignment and he’s critiquing them.

“The photos don’t make me feel anything,” he says.

The day before, I had gone out to shoot photos with an agenda: to find a story about climate change and how it affects people — the same thing I do every day at work. I intended to find a science person to interview about the California drought and work in a climate change angle. But that was not going to happen. The instructors had given us an insanely tight deadline for a series of assignments—all due simultaneously—and restricted the location for our stories. On top of that, I was struggling with unfamiliar equipment.

The instructors also told us not to get blocked into our initial vision. But I was blocked and I was ticked off, too. It was obvious that I was not going to have my way. I felt like I was being pressed into an assignment that was impossible to complete within the allotted time frame. And frankly, I also thought the assignment was beyond my skill set and unrealistic for me.

But the assignment was due and there was no way I was going to quit. I was out in the field, walking around, and I absolutely had to find a stranger, interview him or her and make it work, period, end of story, done. Wandering through my assigned neighborhood, I stopped to admire a well-groomed garden in the front yard of one of the homes. When the homeowner, Migdalia Collazo, walked out onto her porch, I asked if she would allow me to photograph and interview her.

During that first photo shoot, I focused on composition, color, light and context, thinking that was the route to a compelling shot. But my photos were lacking the most important element: a compelling story; something to feel.

After the critique, my teacher’s words stayed with me, reverberating in my head:

                  The photos don’t make me feel anything.

                  The photos don’t make me feel anything.

                  The photos don’t make me feel anything.

As a climate and Earth science communicator, I find this is the biggest challenge. We’re in a constant fight to capture attention, to move people, to make them care about how their behavior is affecting Earth.

To feel something.

But we get caught up with logical analysis of facts and don’t understand why many people don’t hear our stories. This is incredibly frustrating because, for us, climate change is so important, so dire, such a big deal. We desperately want to reach out and let our stories be told; to find the right way for the meaning to get through.

So from now on, I’m committed. My goal is to find a way to inspire you to feel something.

As always, I look forward to your comments.

Want to see something really cool? Duh. JPL's visualization team has updated the International Space Station (ISS) in NASA's Eyes on the Earth app to include the agency's next mission, ISS-RapidScat.

I know what you're thinking: What will RapidScat do, and why is it called that? RapidScat, short for "Rapid Scatterometer" (a scatterometer being a type of radar that bounces microwaves off Earth's surface and measures the strength and direction of return signals), is going to observe ocean winds from the ISS. Ocean winds tell scientists about the complex relationship between the ocean and the atmosphere. The mission will also tell scientists the role the sun's heat plays in creating winds. These data will contribute to both weather (short-term and local) and climate (long-term and global) predictions, such as those related to El Niño.

You might also wonder how it's going to be attached to the ISS. NASA partnered with SpaceX to use the company's Dragon, a free-flying spacecraft that will deliver the instrument to the station. Once there, an arm attached to the station will grab RapidScat from inside the Dragon and install it on the end of the station's Columbus laboratory.

Video of ISS-RapidScat, as seen in NASA's Eyes on the Earth web app. RapidScat is scheduled to launch in September 2014 via a SpaceX Dragon.

So, now there's a virtual RapidScat aboard a virtual ISS in NASA's Eyes on the Earth app. It's awesome and super detailed. In Eyes on the Earth, every spacecraft is a high-end, photorealistic (i.e., closely resembling the real-life spacecraft) rendering created by a 3D art director. You can view the spacecraft orbiting Earth, zoom in and/or access real-time data from your keyboard.

ISS-RapidScat is scheduled to launch in September 2014. Learn more about the science and instrument.

As always, we look forward to your comments.

Flirting with gravity

“If you release the fly bar too early,” explains Richie Gaona, fourth-generation trapeze artist turned trainer, “your trick will go long and you risk banging into the catcher.” We are standing near the net talking about timing. He tosses a gardening glove into the air. It spins and lands a few feet away.

“If you hold on too long, then your trick is short and you’ll miss.” Someone brings back the glove and he throws it again. It goes up spinning, but this time travels backwards. “If you let go at just the right moment, you get vertical lift, then a moment of stillness and end up a perfect arm's distance from the catcher.” The glove goes up, spins twice, and lands squarely where he intended with a satisfying plunk.

When people find out that I work at NASA and fly trapeze, they’re surprised that I have such diverse interests. I don’t see it that way: It’s the same sky, just a different type of rocket.

Richie’s "timing" explanation uses the same principles of physics that NASA uses to deploy many of its spacecraft. A combination of physics and timing is what accounted for the tight 30-second launch window of NASA’s Orbiting Carbon Observatory-2 (OCO-2) earlier this month. OCO-2 must arrive in the A-Train lineup as precisely as a trapeze artist performing a complex acrobatic trick. Two other NASA Earth science missions launching this year, ISS-RapidScat and CATS, will exploit the same science and math equations for their meticulous rendezvous with the International Space Station (ISS).

I never did run away to join the circus. But Kristin Finley, the girl I stood next to for so many years on the platform (just another term for "launch pad"), made it all the way to the top. Although our journeys seem like worlds apart, they're actually more like a parallel universe.

That’s me in the sky over a party. (Credit: Bobby C. King) That’s me in the sky over a party. (Credit: Bobby C. King)

To me, NASA is enough like soaring through the air, shooting for the sky and flirting with the forces of gravity. And even though Kristin has traveled all around the globe, just like one of NASA’s Earth-orbiting satellites, the trapeze troupe she performs with came back into town this week.

So, for a day I ran away (a couple miles downtown, actually) to get swept up in flight, up in the air, thrusting into space and reaching for the sky.

Why do trapeze artists do what they do? The same reason we do what we do at NASA. It’s the attraction to what seems impossible; the relationship with space, to leave the ground and go upward, going as high as you can; to push boundaries using a combination of physics and sheer determination.

We push ourselves for the pure joy of pushing, and the hope that those who watch will be moved and inspired; that someone, somewhere, might see what we’re doing and consider pushing beyond their perceived limits, real or otherwise.

Dear Earth Right Now blog readers,

I appreciate you. I appreciate that you take the time to read these blog posts and that many of you like them, share them and even comment on them. I know it might seem like at NASA we are all a bunch of super intelligent, creative, intuitive space people, but in reality, we’re just like you. We have ups and downs, good days and rough patches. Often it’s the things that appear small that can be inspiring and meaningful, too.

I spend a large portion of my workday looking at satellite images of Earth, an amazingly glorious expanded view. This view from far above gives me a unique window into places on our planet that I haven’t been to, or places that maybe I’ll never ever go. It’s like looking at life or life’s problems from a distance can actually put everything into perspective.

All of us—you and I—we are together on this planet. We don’t need to travel very far to get excited. We can be astounded by what’s here.

Thanks to all of you again!

Laura

Oh, what a night

There we stood for the second night in a row, looking into the distance at 2:30 in the morning, feeling the cool, still quiet of the nighttime air. Just like last night, I wasn’t tired at all. It was probably cautious optimism giving me just enough energy to stay alert. We could hear the live broadcast of the Orbiting Carbon Observatory-2 (OCO-2) launch over the NASA Television feed. Those of us still in town and eager to wake up in the middle of the night to watch the launch could see live, up-close shots of the Delta II rocket on the launch pad (which stood just west of where I was standing), intercut with views of what was going on in the control room at Vandenberg Air Force Base. We could hear the launch team as it went through its list of final preparations. We could hear the final countdown.

At 2:56 a.m. PDT (5:56 a.m. EDT), OCO-2 lifted off on a United Launch Alliance Delta II rocket. My eyes strained to follow the rocket into the sky. If you were one of the people who watched the launch on NASA Television from home instead of being closer to the action like I was, you probably had just as good a view. Unlike two nights ago, which was clear, the California marine layer moved in last night, making it hard to see much.

I remained still, looking skyward, breathing, wondering, quiet. I could hear NASA TV tracking the rocket into the night sky. I thought about all of the knowledge that science has given us, and all that we have yet to learn. A camera installed on the launch vehicle showed the observatory smoothly separating from the rocket's second stage. A few minutes later, ground- and space-based antennas detected signals telling us that the observatory unfurled its twin sets of solar arrays. OCO-2 will join its sister satellites, the fleet of Earth-observing missions that help us understand the mysteries of the planet we call home.

My thoughts meandered back to the many times I looked down from the high bay at JPL’s Spacecraft Assembly Facility, often bringing my college students there. Now both OCO-2 and the students would pass their tests and graduate at nearly the same time. NASA’s mission is “to reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind.” But we also seek to inspire. We seek to inspire people all around the world, to inspire future scientists and engineers, and even to inspire ourselves.

I stayed awake for another hour or so watching the commentary on NASA TV. As I rested my head on my pillow at around 4:00 a.m., I was left alone with my thoughts of the night sky, and of the vastness of space, the wonder of new frontiers of science and my dreams of inspiration.

Thank you for your comments and have a wonderful and safe 4th of July holiday.

How many scientists does it take to launch a NASA satellite into space?

How many scientists, engineers and support crew does it take to launch a rocket with a NASA satellite into space? More than it takes to screw in a light bulb, that’s for sure. A big team collaborated on NASA’s Orbiting Carbon Observatory-2 (OCO-2)—a custom built, hand-crafted, experimental instrument—and prepared it for launch into orbit. I mean, it's not like you can actually buy a shiny new "prefab" science satellite off a store shelf.

As the July 1 launch creeps closer, the OCO-2 science team has been almost too busy to breathe. I caught Deputy Project Scientist Annmarie Eldering rushing between meetings to prepare for a Discovery News Earth-themed Google hangout. She was too busy to talk.

Dave Crisp OCO-2 Science Team Leader Dave Crisp poses with a model of the mission.
On the other hand, Science Team Leader David Crisp, is so proud of OCO-2 that he and I spent over an hour yacking away about the mission, even though he often has a line of people outside his office waiting to talk to him. And I spent another afternoon discussing launch plans with Project Scientist Mike Gunson.

If you were a fly buzzing through the halls of JPL, this is the sort of interesting information you might be surprised to learn about carbon dioxide (CO2) and NASA’s newest OCO-2 observatory:

  • As of now, there are between 70-150 ground-based stations around the world that measure CO2. At each of those stations, very precise measurements are made that tell us what’s happening at that individual location. Taken together, they give an average measurement for Earth’s whole atmosphere.
  • The reason NASA even has an OCO-2 mission is that we would never have enough ground-based CO2 measurements to figure out all the human processes that emit CO2 plus all the natural processes that both emit and absorb it, so we need to measure CO2 from space.
  • This new observatory will give us details about where, as one scientist put it, “every single CO2 molecule is going."
  • Human activity produces more CO2 (currently 35-40 billion tons annually) than any other greenhouse gas. Therefore, it can be said that CO2 is the principal anthropogenic greenhouse gas driving climate change.
  • Once the CO2 gets into Earth’s atmosphere, the only way for it to leave is by being absorbed into the ocean or taken in by plants. The CO2 that stays in the Earth's atmosphere may stay there a thousand years.
  • The fact that CO2 stays in the atmosphere such a long time means that it’s mixed into the atmosphere really well, which makes measuring small variations very difficult. That's why NASA’s OCO-2 instruments must be extremely precise.
  • To design instruments to be sensitive enough to measure CO2, scientists borrowed ideas from the practice of measuring the thermal radiation that shines through the clouds on Venus' dim night side.
  • OCO-2 sits atop a Delta II rocket, which is scheduled to launch on July 1 at 2:56 a.m. PT. There is only a 30-second launch window.
  • A number of weather issues could cause a postponement. These include thunderstorms and lightening, anvil clouds or conditions that cause hail. Everyone is excitedly checking the weather; atmospheric scientists love weather. The forecast for Vandenberg Air Force Base on the California coast (where the launch will take place) is clear and calm. (Yay!)
  • Fifty-two minutes after launch, separation of the OCO-2 observatory from the launch vehicle second stage will occur. Three minutes after that, the observatory’s solar panels will deploy and the satellite will have enough juice to send us a 'Hi, I’m powered on' message.
  • Once we begin to receive detailed data from OCO-2, NASA scientists will be extremely careful to compare and validate (double-check) the data from space against ground-based measurements before it's released to the public. This information is crucial and, at NASA, it’s our job to ensure that what we report is accurate and verified.

This weekend, I’ll be heading up the coast to tweet, post and blog about the launch. Follow along at these links:

This video shows NASA’s OCO-2 satellite as seen in NASA’s Eyes on the Earth 3D web application.

Human activities add over 39 billion tons of carbon dioxide (CO2) into Earth’s atmosphere every year. If every living man, woman and child on the planet contributed equally to the problem, that would come out to five and a half tons of emitted CO2 per person. But some carbon footprints are larger than others. On average, each person in the U.S. produces about 16 tons of CO2 per year mostly by burning coal, oil and natural gas.

NASA’s new Orbiting Carbon Observatory-2 (OCO-2) has the potential to be a game changer. The technology on OCO-2 is so sensitive that every day scientists will have 100 times more measurements than they presently do.

OCO-2 is scheduled to launch on July 1, 2014. Find out more about the science, spacecraft and instrument at Orbiting Carbon Observatory-2 (OCO-2).

Excited about OCO-2? Are you kidding?

NASA's Orbiting Carbon Observatory-2 (OCO-2) uncrated after arriving at Vandenberg Air Force Base (VAFB). OCO-2, scheduled for a July 1 launch, is the agency's first carbon-counting mission.

Ask any of the teams of scientists, project engineers, system engineers, technicians or support crew preparing for NASA’s Orbiting Carbon Observatory-2 (OCO-2) launch scheduled for July 1 if they’re excited. The answer will be something like “we’re too busy to get excited yet.”  

I feel the same way. The launch is weeks away, and at JPL we are busy, busy, busy. There’s so much to do before the launch to make sure all systems are go; that both the spacecraft and the rocket are okay.

Delta II rocket on which OCO-2 will be launched into space. Delta II rocket on which OCO-2 will be launched into space.
Right now the spacecraft is at Vandenberg Air Force Base inside the Astrotech building, where the spacecraft hardware is being processed. What that means is that before OCO-2 goes into the Delta II rocket that will take it into orbit, it must go through a series of final tests and inspections—a chance to have human hands or eyes on it before it is put atop the rocket and blasts off into space. The "remove-before-flight" plugs are getting removed and the "install-before-flight" plugs are getting installed. The special spacecraft fuel needed to maneuver the spacecraft as it turns and twists toward Earth is being added. 

The network connectivity and data flow from the spacecraft to the mission operations center, the ground network antennas and the operational readiness tests, including mission simulations where technicians and engineers simulate early operations and operation contingency, are performed. Finally, there is a last-minute closeout inspection.

If all goes as planned, the observatory will go onto the rocket at the end of this week.

Oh, and I lied earlier. I actually am excited. I hope you are, too.

A taste of NASA

Edible model of OCO-2, NASA's soon-to-launch carbon-counting satellite.

Feast your eyes on my latest edible satellite model: NASA’s Orbiting Carbon Observatory-2 (OCO-2). Go ahead and laugh if you want—creating it was harder than it looks, and getting a decent photo was even more of a challenge. I created this food model to commemorate the upcoming launch (July 1, 2014) of NASA’s latest climate satellite, which will precisely monitor and map carbon dioxide in Earth’s atmosphere.

As with the model I created to pay tribute to the Global Precipitation Measurement (GPM) mission, this one was made of foods that I actually ate, so nothing went to waste. The radish and kale were harvested from my garden. The body of the satellite is a carved pineapple, the solar array is made from lettuce, the star tracker is a carrot, the vent pipe is a kale stalk, the instrument radiator is made of dried mango and the space blanket is dried kelp and radish. By looking closely at the instruments' designs to create the food model, I had to learn and understand more about this mission than I would merely studying a graphic or line drawing.

I encourage you to make your own NASA OCO-2 satellite model and to share your photos in the comments section. The spacecraft detail drawing is shown below, and you can learn about the OCO-2 mission and see more illustrations on the mission home page: http://oco.jpl.nasa.gov/.

I look forward to your comments and creativity.
