From shoveling the third heavy snowfall of winter to spotting the first crocus of spring, each day without fail we experience our environment. Meaning each of us is a potential wealth of information about our local environment. Information that if gathered could inform climate scientists about the local effects and potential indicators of climate change. This is the premise of iSeeChange, a crowdsourced journal of community submitted local weather and environment observations.
The variability of weather and environmental conditions is an inherent challenge in climate science. Is the current drought in California a result of climate change or just an extreme version of the state’s periodic droughts? Was the devastation of Hurricane Sandy a fluke event or foreshadowing of a future trend?
To address this variability, climate scientists collect and average data across large spans of time and space. But managing data this way poses its own issues. “Climate science has a difficult time drilling down and being relevant to everyday people making every day decisions,” says Julia Kumari Drapkin creator of iSeeChange. “We designed iSeeChange to bridge the gap between the big data that the scientists collect and the local experiences of individuals and communities. The project allows people to reach their hands up and meet the big data half way overcoming this problem of scale.”
Since its creation in 2012, iSeeChange has grown from a local weather almanac in Colorado to a nationwide environmental reporting network. Anyone can become a member and submit observations on the website. Viewers can sort through the data by date or season, refining their search through metrics such as humidity, precipitation or cloud cover. Ideally members submit data on a weekly basis but in reality participation can range from a single backyard photo to religiously gathered measurements. One iSeeChange member uploaded observations made in a journal kept by a Dust Bowl era fruit farmer, noted Julia.
But beyond a data repository, the purpose of the project is to encourage conversation between scientists, journalists and individuals. “We want people to be curious, ask questions about what they see and experience. Then scientists and journalists in our network try to answer those questions,” says Drapkin. “The posts help scientists and journalist as well. Member submissions call attention to interesting or unusual events, which get picked up by journalists, transforming a few individual’s observations into a larger story.”
And these stories will become informative climate data for the future. Already researchers are expressing interest in the data. The project’s growth and collaborations with scientific partners at NASA, UC Berkeley and Yale is setting the stage for a larger impact. Due out in summer, iSeeChange co-developed an app with NASA that will ping community members to send in local observations whenever satellites are overhead. “The app will allow for real time comparisons between what the satellite sees and what is happening on a local level,” explains Drapkin. “We will learn what the impacts are and why it matters. We will be able to take the quantitative data and match it to the qualitative data and see how they compare over time.”
Ultimately iSeeChange is about empowering individuals and communities to document and investigate their environment. “People are experts of their own backyards. The granular changes they observe add up to bigger picture changes,” says Drapkin. “Already, these community observations have given scientists and journalist new insights and heads up on environmental trends.”
If you collect data about your local environment, want to share an interesting change you have notice or have a question you, visit iSeeChange and become part of a large scale effort to document your environment. To learn more about iSeeChange view their trailer.
What do Buzz Aldrin’s shoe, the Liberty Bell & sports arenas all have in common? Watch Space to Ground, your weekly update on what’s happening aboard the International Space Station.
SciStarter’s Project MERCCURI, a research project to compare microbes on Earth and in space (presented by the Eisen Lab and UC Davis, SciStarter and Science Cheerleader, with support from the Sloan Foundation, Space Florida and NanoRacks), was featured on NASA’s “Space to Ground,” a weekly update on what’s happening aboard the International Space Station.

Microbe Growth Documented for Analysis and Interpretation by UC Davis Scientists
Davis, CA. (December 10, 2014) – This week on the International Space Station, astronaut Terry Virts is measuring the growth of microbes collected by citizen scientists across the United States.
This citizen science research, known as Project MERCCURI, investigates how microbes from different places on Earth compare to each other and to those found on the International Space Station.
The microbes shot into space on a SpaceX Falcon 9 rocket in April of this year. The microbes rested in a freezer at -80°C until the testing began earlier this week. UC Davis has received confirmation that the microbes are now growing in space, and the team in the Microbiology Lab will soon analyze the data on the individual microbes to see which won the “Microbial Playoffs.” Scientists are looking for winning microbes in three different categories: Read the rest of this entry »
In August, we shared information about NASA’s Asteroid Initiative and Cooperative Agreement with ECAST (Expert and Citizen Assessment of Science and Technology), to enable everyday citizens to have a say in the future of space exploration.
How does the online citizens’ forum work?
Two in-person deliberations will take place on 11/8 in Phoenix, AZ at Arizona State University and on 11/15 in Cambridge, MA at the Museum of Science. To make sure anyone, anywhere can participate, SciStarter (a founder partner of ECAST) created a three tiered online deliberation platform which will be ready for YOU next week! But you’ll need to sign up by Thursday, 11/6 to be eligible.
As a registered participant in the online deliberation, you will have access to the same background information as the folks at the in-person events will have and you’ll be able to ask questions, and weigh in with thoughts and opinions while guided by an online facilitator. AND, you will have three days to drop in and out at your convenience.
All responses will be aggregated and included in a formal report to NASA. If you can’t make the in-person or online deliberation next week, don’t worry! You’ll still have a chance to weigh in on the outcomes of deliberations in the coming weeks!
Who can participate?
You don’t have to be a rocket scientist to participate. You also do not need to know any information about the Asteroid Initiative as all the background information required will be provided. In fact the forum is centered around the idea that every citizen who is interested in contributing will be able to do so. So your interest in participation is all that counts!
Why should you act now to be a part of this?
The online deliberation is scheduled for next week and in order to participate, you have to register quickly as the deadline is fast approaching. Sign up on the ECAST website before November 6th and complete the required demographic and opinion survey to access the online deliberation platform. This is your chance to help NASA make the next giant leap in space. Don’t miss it!
Buckle up folks, ‘cause NASA is coming to you with a challenge. On Saturday, NASA announced at the World Maker Faire in New York that it has opened up registration for the ‘Mars Balance Mass Challenge’. The space agency has had a history of engaging citizen scientists through online crowdsourcing initiatives such as Target Asteroids!, Planet Mappers and Be a Martian and on the ground challenges such as its annual Sample Return Robot Challenge. In August this year, they partnered with ECAST (Expert and Citizen Assessment of Science and Technology) for the ‘Informing NASA’s Asteroid Initiative’ which invites the public to discuss and comment on how NASA is tackling asteroid exploration, potential asteroid threats and planetary defense.
So what is the Mars Balance Mass challenge all about? The exploration of Mars is one of the agency’s major projects. Since its inception, the Mars Exploration Program (MEP) has conducted extensive studies in an effort to understand its climate, natural resources and importantly the possibility of life on Mars. In one such mission in 2012, NASA landed the robotic space probe Mars Science Laboratory (MSL) on the surface of Mars. To accurately land at a predetermined site the probe used a precision guided system which included two ejectable ‘balance masses’ made of tungsten weighing 150 kg (approximately 330 lb) each. The first balance mass comprising of two 165-pound weights was ejected before entering the atmosphere of Mars to offset the spacecraft’s center of gravity during entry. The second balance mass, made up of six 55-pound weights was expelled after atmospheric entry and rebalanced the center of gravity of the craft just before the parachute was deployed 1,2. (You can even see images of the impact craters created by these balance weights on the surface of Mars. Pretty cool huh?)
So how does this relate to the challenge? In the 2012 mission, these balance masses were simply tungsten dead weights. For the challenge, the question that NASA wants your help to answer is
“If you had up to 150 kg of ejectable mass prior to entry and another 150 kg during the entry and landing phase of a Mars mission, what could you do with it that was useful and advances knowledge in a scientific or technological way?”
In other words, by replacing the balance masses in future missions with a useful payload, NASA is hoping to kill two birds with one stone. Perform the function of the balance masses and acquire additional knowledge. Partnering with Innocentive Inc., NASA is offering a prize of $20,000 to the winning proposal. According to their website, this is a “Theoretical Challenge” which means that citizen scientists need only to submit a written proposal, though “ideas, drawings, and detailed procedures are required.”
In an official press release by NASA, Lisa May, lead program executive for NASA’s Mars exploration program said, “We want people to get involved in our journey to Mars. This challenge is a creative way to bring innovative ideas into our planning process, and perhaps help NASA find another way to pack more science and technology into a mission.” The challenge already has garnered significant interest with 215 226 active participants and counting (at the time of writing) within only two days since it was opened to the public. Participation can be on an individual basis or a team effort. For teams, Innocentive offers online workspaces known as Team Project Rooms to collaborate efficiently and document the process.
The Mars Balance Challenge is part of the launch of a larger initiative known as NASA Solve, an online platform which lists all the opportunities available to the general public. These challenges are ones that NASA needs the help of citizen scientists in solving. “NASA is committed to engaging the public, and specifically the maker community through innovative activities like the Mars Balance Mass Challenge, and NASA Solve is a great way for members of the public, makers and other citizen scientists to see all NASA challenges and prizes in one location,” said NASA Chief Technologist David Miller in the press release.
Ideas for the Mars Balance Mass Challenge are not limited to any specific discipline so the (Mars) sky is the limit. Fire up your imaginations, hone your google search skills and start cracking!
