A story about open science

A talk by Geert Barentsen for dot Astronomy 8 held at Oxford University in 2016.

Transcript

1. A story about open science
2. NASA budget as a percentage of the US federal budget
3. Kepler Mission $0.6 billion Humanity can afford space science 2022 Qatar World Cup $220 billion
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: MNRAS 90% 87% ApJ Icarus 19% Source: https://gist.github.com/barentsen/99c9d5fab8fefdd46a1e
7. We need our flagship facilities and missions to embrace extreme openness
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 1 or 30 min cadence
12. 2009-2013 Kepler monitored 200,000 stars for 4 years
14. Kepler’s 4696 Planet Candidates
15. Kepler data contributed to 1,649 publications so far https:/ /github.com/KeplerGO/kpub

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.
27. TITLE OF A PAPER YOU WANTED TO WRITE “But I 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 itself
32. Apr-Jun 2016 Jul-Sep 2016 The K2 mission now surveys different fields along the ecliptic
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.
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.
45. Image: NASA The future is open
46. Wouldn’t it be nice of all missions exposed their raw data?
47. NASA budget as a percentage of the US federal budget
