Electron Losses and Fields Investigation (ELFIN)

In-Situ Probe · Competed · PI-led · Launched on September 15, 2018 · Completed · LCC: $4.0M/$5.4M (2025 $)Life-cycle cost: NASA’s reported cost to build, launch, and operate a mission through its prime mission, plus documented partner contributions, in 2025 dollars. Extended missions are not included. Methods · Wikipedia

Scope Active Mission WindowActivePapers published from the first full month after science operations begin through two years after the mission ends. Citations are counted through the third calendar year after each paper appears. For ELFIN, papers published October 1, 2018 to January 1, 2024. Methods LifetimeLifetimeEvery tracked publication to date, with every citation to date. For ELFIN, papers published from 2020 to November 3, 2026. Methods
Tracked publicationsTracked publications: peer-reviewed papers we found that name the mission or its instruments in their titles, abstracts, or keywords. Papers that used the data without naming it are missed. Methods70
CitationsCitations: every citation these publications have drawn to date. Older missions have had longer to collect them. Methods1,151
Citation indices
h-indexh-index: the largest h such that h papers have at least h citations each. It only grows with time, so older missions score higher. Methods20
g-indexg-index: the largest g for which the g most-cited papers together hold at least g² citations. Like the h-index, but it lets the most-cited papers count for more. Methods31
m-indexm-index: a mission’s h-index divided by the years since its first peer-reviewed paper. It falls every 1 January even when nothing else changes; the figure shown is as of November 3, 2026. It also discounts the long operating life that larger missions paid for. Methods2.9
toritori (total research impact, from SciX): for every paper citing one of the mission’s papers, 1 divided by the citing paper’s reference count times the cited paper’s author count, summed, with self-citations removed. It favors citations from papers with short reference lists and from outside the mission’s own authors. Computed over the tracked citation graph, which can be slightly incomplete. Always over every tracked publication to date, whichever scope is chosen. Methods1.8
riqriq (research impact quotient): 1,000 times the square root of tori, divided by the years since the mission’s first paper. A rate, not a total, so it does not keep growing with age the way the h-index and tori do. Like tori, always over every tracked publication to date. Methods192
