Space Exploration: Not Just for Rocket Scientists

Ariel Waldman—founder of Spacehack.org, global director of Science Hack Day, author of What's It Like in Space?, and NASA Innovative Advanced Concepts (NIAC) Program council member—gave the keynote at a recent NASA conference in Denver, Colorado.

PCMag was there and sat down with Waldman afterwards to talk about her former role at NASA AMES CoLab; sci-fi space mission concepts; how she came to co-author a report on the future of human spaceflight, and what she thinks of Elon Musk.

Here are edited and condensed excerpts from our conversation.

Ariel, what was the best thing about working at NASA AMES?
We did a lot of cool things at NASA CoLab, and I've incorporated much of the learnings into the work I do now. We created coworking environments in San Francisco for people to collaborate alongside space scientists, built open source projects, and did a lecture series to encourage cross-disciplinary projects. I also consulted with different NASA missions to open up their data. For example, on LCROSS, which was a lunar mission to impact the moon, we worked with NASA personnel to create an interface so that amateur astronomers could collaborate with them and contribute their own data.

Your work at NASA—and afterwards—has made the case that human exploration, and eventual creation of off-world settlements, will need many different types of people, not just rocket scientists.
Agreed. As I said here today, in my speech, there's been something of a monoculture in the past 50 years and it's necessary to break that open. Yes, ivory tower cultures can technically survive without being diverse, we know that, but that's not the point. Simply put, they're being reckless and less effective by not opening up to a wider pool of people. I was added to the external council of NIAC in 2015, and I'm the only non-doctorate. I'm kind of proud of that because it's been my own choice not to pursue that direction and, I believe, for me, having a different life and education experience is most effective for my work at NIAC.

What do you do at NIAC specifically?
As council members, we provide guidance that helps steer the program. We don't pick and choose who gets awarded. Which means I can do direct outreach to encourage people to apply, without having a conflict. My big mission is to get people outside of space science and the space industry as a whole, to apply their existing research, often in unrelated fields—biology and neuroscience and so on—and apply them to space mission concepts in a really profound way. NIAC is great for funding the overlooked or underfunded areas. If someone has a really cool idea, NIAC is a good place to find a home; it's become an incubator for wayward projects. I have the luxury of being very multidisciplinary, so I can find ways, for example, for a jellyfish biologist to work with a particle physicist.

When not on NIAC business, you also run Spacehack.org to give people ways to get involved in space exploration.
I wanted people to feel they had a part to play. For example, we include projects such as Galaxy Zoo Radio. They're concerned with observations of supermassive black holes and their host galaxies in radio and infrared wavelengths. They welcome participants in this research as, when more data is created, they can make ever more accurate models of how supermassive black holes work.

Switching gears, how did you get involved in plotting the trajectory of human spaceflight by co-authoring the Congressionally requested National Academy of Sciences report?
That may have come about because I was asked to keynote at DARPA's 100 Year Starship Symposium in 2011. The National Academies asked me to participate because they were curating an unusual and topically diverse committee to report on the future of human spaceflight. They brought on planetary scientists, economists, historians, particle physicists and then me—I was the youngest on the council by a few decades [Laughs]. As part of the committee's tasks, we looked into why we as a society, and a federal agency, do human spaceflight in the first place. It was an unusual premise for the National Academy of Sciences. One of the most profound findings was that there is not one specific rationale; it's the combination of pragmatic and inspirational rationales that argues for a continuation of human exploration of the solar system.


There are an increasing number of people in the human spaceflight business, too, like Elon Musk. Any comment there?
It's so interesting because, take Elon Musk and his rationale of "the survival of the species" [and] he makes it sound as if his rationale is the only one. But any single rationale doesn't make for a compelling argument, nor does any one rationale garner majority support. It's truly the combination of multiple rationales that argue for a continuation of human space exploration.

Random question: Any geek apps on your phone? Do you run the SETI browser on your laptop?
I had it running for a little while, and I'm now friends with people at SETI so that's cool. There's a bunch of apps that I download, keep for a month, then uninstall, because they take up so much space on the phone. Having said that, I have the NASA TV app because who doesn't like to watch live rocket launches on their phone?

Final question: what's next for you?
Science Hack Day, a two-day event, which I've been organizing since 2010, after being on a panel at SXSW, is now in over 25 countries, and our next event is in San Francisco on Oct. 14-15. Anyone can create a Science Hack Day in their own city by checking out the How-To Guide. I've also started a YouTube channel about space exploration that's a lot of fun. For the next few months, I'm taking a microscopy class and waiting for a response on my grant proposal to go to Antarctica to image microbial life under the ice. I met many astrobiologists at NASA and the subject fascinates me, so that's—hopefully—what I'm doing next.

Facebook mistakenly leaked developer analytics reports to testers

Set the “days without a Facebook’s privacy problem” counter to zero. This week, an alarmed developer contacted TechCrunch, informing us that their Facebook App Analytics weekly summary email had been delivered to someone outside their company. It contains sensitive business information including weekly average users, page views, and new users. 43 hours after we contacted Facebook about the issue, the social network now confirms to TechCrunch that 3 percent of apps using Facebook Analytics had their weekly summary reports sent to their app’s testers, instead of only the app’s developers, admins, and analysts. Testers are often people outside of a developer’s company. If the leaked info got to an app’s competitors, it could provide them an advantage. At least they weren’t allowed to click through to view more extensive historical analytics data on Facebook’s site. Facebook tells us it has fixed the problem and no personally identifiable information or contact info was improperly disclosed. It plans to notify all impacted developers about the leak today and has already begun. Below you can find the email the company is sending: Subject line: We recently resolved an error with your weekly summary email We wanted to let you know about a recent error where a summary e-mail from Facebook Analytics about your app was sent to testers of your app ‘[APP NAME WILL BE DYNAMICALLY INSERTED HERE]’. As you know, we send weekly summary emails to keep you up to date with some of your top-level metrics — these emails go to people you’ve identified as Admins, Analysts and Developers. You can also add Testers to your account, people designated by you to help test your apps when they’re in development. We mistakenly sent the last weekly email summary to your Testers, in addition to the usual group of Admins, Analysts and Developers who get updates. Testers were only able to see the high-level summary information in the email, and were not able to access any other account information; if they clicked “View Dashboard” they did not have access to any of your Facebook Analytics information. We apologize for the error and have made updates to prevent this from happening again. One affected developer told TechCrunch “Not sure why it would ever be appropriate to send business metrics to an app user. When I created my app (in beta) I added dozens of people as testers as it only meant they could login to the app…not access info!” They’re still waiting for the disclosure from Facebook. Facebook wouldn’t disclose a ballpark number of apps impacted by the error. Last year it announced 1 million apps, sites, and bots were on Facebook Analytics. However, this issue only affected apps, and only 3% of them. The mistake comes just weeks after a bug caused 14 million users’ Facebook status update composers to change their default privacy setting to public. And Facebook has had problems with misdelivering business information before. In 2014, Facebook accidentally sent advertisers receipts for other business’ ad campaigns, causing significant confusion. The company has also misreported metrics about Page reach and more on several occasions. Though user data didn’t leak and today’s issue isn’t as severe as others Facebook has dealt with, developers still consider their business metrics to be private, making this a breach of that privacy. While Facebook has been working diligently to patch app platform privacy holes since the Cambridge Analytica scandal, removing access to many APIs and strengthening human reviews of apps, issues like today’s make it hard to believe Facebook has a proper handle on the data of its 2 billion users.
