Space in 150 years: From fantasy through fiction to fact and function [PDF]

, 2015
In the last century and a half, space has moved from the realm of fantasy to everyday reality. In parallel, the way space has been regarded by the person in the street and the ideas of what access to space might be used for have evolved extraordinarily.

James van Allen and his namesake NASA mission [PDF]

, 2013
In many ways, James A. Van Allen defined and “invented” modern space research. His example showed the way for government-university partners to pursue basic research that also served important national and international goals.

2006 Fragmentation of Comet 73P/Schwassmann-Wachmann 3B Observed with Subaru/Suprime-Cam

, 2009
We analyzed the Subaru/Suprime-Cam images of 73P/Schwassmann-Wachmann 3B and detected no fewer than 154 mini-comets. We applied synchrone-syndyne analysis, modified for rocket effect analysis, to the mini-fragment spatial distribution. We found that most

Review of asteroid, meteor, and meteorite‐type links

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Ceres: Organic‐Rich Sites of Exogenic Origin?

AGU Advances, Volume 6, Issue 1, February 2025.
Abstract Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari and Urvara craters. The origin of organics, either endogenic or exogenic, in these fresh exposures is still

Evidence for Magnetically‐Driven Accretion in the Distal Solar System

AGU Advances, Volume 5, Issue 6, December 2024.
Abstract Paleomagnetic measurements of meteorites indicate that magnetic fields existed in the inner solar nebula capable of driving accretion at rates similar to those observed for young stellar objects with protoplanetary disks. However, the field strength in the solar system beyond ∼7 astronomical units (AU) and its role in accretion remain poorly ...

The Carbon Monoxide Abundance in Comet 103P/Hartley during the EPOXI Flyby

, 2011
We report the detection of several emission bands in the CO Fourth Positive Group from comet 103P/Hartley during ultraviolet spectroscopic observations from the Hubble Space Telescope (HST) on 2010 November 4 near the time of closest approach by NASA's ...

SPICA infrared coronagraph for the direct observation of exo-planets

, 2010
We present a MIR coronagraph to target the direct observation of extrasolar planets for SPICA, in which a coronagraph is currently regarded as an option of the focal plane instruments. The primary target of the SPICA coronagraph is the direct observation
