Panel: Bringing Space Exploration Down to Earth
At 5:00pm on Friday, Brian McLaughlin and Sara Mitchell presented their fascinating panel on Bringing Space Exploration Down to Earth. While not officially representing NASA at Intervention, both Brian and Sara work at the Goddard Space Flight Center, and were happy to share details on the wealth of science information available for free on the Internet.
Some of the sites mentioned included:
* The Earth Observatory Website, which provides images from weather and earth-observing satellites. It also provides worldwide maps of radiation, temperature, and other factors which can be used to monitor climate change.
The NOAA National Environment Satellite, Data, and Information Service (NESDIS), provides information on geostationary and polar-orbiting satellites.
* The NASA Lunar Science Institute provides data on various lunar missions.
The High Energy Astrophysics Archive Service has terabytes of mission data available to access in an a standardized format (FITS files). It also provides tools for analyzing the data.
The panelists noted that NASA images and mission data are public domain. For those of you looking for awesome desktops, NASA has many “pictures of the day” sites that can be found by searching on Google.
However, NASA’s data is useful for so much more than cool pictures. Since sending up your own satellite can be extremely expensive, many groups use NASA and NOAA data for their own applications. For example, Google Earth’s cloud data comes from NASA GOES satellites. Commercial vendors also use weather data provided for planning supply and demand.
To help budding astronomers learn how to analyze the wealth of data available, Brian and Sara spoke of a site called Imagine the Universe. This NASA-created site is geared towards high school students, with general information on astronomy and a variety of tools for teachers. It also contains a program called HERA, a fairly simple analysis program for FITS files, with tutorials on how to use it.
The panelists encouraged attendees to take advantage of the opportunity to perform Citizen Science. Citizen Science – the idea that anyone can access data and do research on it – has exploded in the last five years. They mentioned that NASA often works with amateur astronomers on projects, and regularly has college students make unguided discoveries based on publicly-available data. There are still some tasks (such as pattern matching) that are difficult for computers, and require human intervention. Because of this, there are sites dedicated to asking the public to help contribute to science. (They mentioned one, called GalaxyZoo, where users could help to classify galaxies.)
At the end of the panel, Brian and Sara both said they could be contacted for more information.
