Consequences of asteroid fragmentation during impact hazard mitigation
, 2009 The consequences of the fragmentation of an Earth-threatening asteroid due to an attempted deflection are examined in this paper. The minimum required energy for a successful impulsive deflection of a threatening object is computed and compared to the ...

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The rise of quantitative geosciences approaches and accessible computer science tools have led to increasing overlap and opportunity at the boundaries of both fields. The need for both research innovation and student cross‐training has motivated new, interdisciplinary Computer Science‐Geoscience collaborations.

A hot terrestrial planet orbiting the bright M dwarf L 168-9 unveiled by TESS
, 2020 © ESO 2020. We report the detection of a transiting super-Earth-sized planet (R = 1.39 ± 0.09 R⊕ ) in a 1.4-day orbit around L 168-9 (TOI-134), a bright M1V dwarf (V = 11, K = 7.1) located at 25.15 ± 0.02 pc.

ALERA‐V Version 1.0: An Objective Analysis Dataset of the Venus Atmosphere
Geoscience Data Journal, Volume 13, Issue 3, July 2026.Using observations from the Venus orbiter Akatsuki, we present the first objective analysis dataset of the Venus atmosphere. ALERA‐V, generated with the ALEDAS‐V system using the LETKF, is expected to support studies of atmospheric dynamics and the planning of future satellite missions.

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Auroral transport models (ATMs) play an important role in quantitative studies of optical auroras, their driving mechanisms, and their effects on the ionosphere and thermosphere. TREx‐ATM was initially developed as the support model for the Transition Region Explorer (TREx) mission, and has gained increasing applications in the community in ...
