  4. “Open science is the movement to make scientific research, data

    and dissemination accessible to all levels of an inquiring society, amateur or professional.” – Wikipedia
  5. Fraction of papers on the arXiv in 2015, by journal:

  8. A story about open science featuring NASA’s Kepler/K2 mission

  9. A story about open science featuring a mission that got

    rid of proprietary data
  10. Kepler/K2 offers an example of extreme openness

  11. 1-meter Schmidt Kepler launched in March 2009 100 megapixel array

  23. Using proprietary data as a reward system bears a significant

    cost … we are slowing down science by 1 to 5+ years; we are reducing the impact of limited-lifetime missions; we are blocking early-career researchers from showing their skills & talents; we are reducing diversity by reserving facilities for rich institutions; we are discouraging the public from active participation in science.

    might get scooped!”
  28. We can have more than one paper on the same

    data or discovery
  29. Slide from https:/ /speakerdeck.com/jakevdp/in-defense-of-extreme-openness

  30. So what about Kepler/K2?

  31. As of 2014 Kepler uses solar photon pressure to balance

  32. Apr-Jun 2016 Jul-Sep 2016 The K2 mission now surveys different

    fields along the ecliptic
  33. None
  34. None
  35. Rebull et al. 2016

  36. K2 data shows significant systematics due to targets drifting 1-2px

    across the detector Vanderburg et al. 2015
  37. Faced by a limited lifetime and new systematics, K2 took

    the open approach: – No proprietary data: all those with the right skills and talents can benefit from the data. – Competition: we fund different groups to do the same science ($10k-$150k grants). – Community products: large, funded K2 programs are required to release value-added data and software.
  38. None
  39. Open sharing of planet candidates and follow-up observations

  40. K2 data contributed to 137 publications so far

  41. K2’s early productivity outperforms Kepler’s! Kepler exoplanet papers (first two

    years) K2 exoplanet papers (first two years) 42 48 K2 literature features more unique authors & more unique institutions.
  42. K2’s open data policy empowers early-career astronomers

  43. NASA’s 2016 Astrophysics Senior Review

  44. Call to action Question the use of restrictive policies and

    proprietary periods; they are harmful to science and to early-career astronomers. Question the notion that we can’t have more than one paper on the same data or discovery. Don’t fear your colleagues, fear losing public support for science.

  46. Wouldn’t it be nice of all missions exposed their raw

  47. NASA budget as a percentage of the US federal budget
