Project Lyra: Catching 1I/'Oumuamua Using Nuclear Thermal Rockets [PDF]
, 2020 The first definite interstellar object observed in our solar system was discovered in October of 2017 and was subsequently designated 1I/'Oumuamua. In addition to its extrasolar origin, observations and analysis of this object indicate some unusual features which can only be explained by in-situ exploration.

Asteroid families in the first order resonances with Jupiter [PDF]
Monthly Notices of the Royal Astronomical Society 390 (2008),
715-732, 2011 Asteroids residing in the first-order mean motion resonances with Jupiter hold important information about the processes that set the final architecture of giant planets. Here we revise current populations of objects in the J2/1 (Hecuba-gap group), J3/2 (Hilda group) and J4/3 (Thule group) resonances.

Radio observations of Jupiter-family comets [PDF]
Planet.Space Sci. 57:1162-1174,2009, 2008 Radio observations from decimetric to submillimetric wavelengths are now a basic tool for the investigation of comets. Spectroscopic observations allow us i) to monitor the gas production rate of the comets, by directly observing the water molecule, or by observing secondary products (e.g., the OH radical) or minor species (e.g., HCN); ii) to ...

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 ...

Meteoritics &Planetary Science, Volume 59, Issue 6, Page 1236-1257, June 2024.Abstract Cosmic dust particles originate from a wide variety of solar system and interstellar objects, including sources not identified among meteorite collections. Particles that survive atmospheric entry are retrieved on the Earth's surface as micrometeorites. The recovery of these micrometeorites has recently advanced to rooftop sites.

The Composition of Dust in Jupiter-Family Comets as Inferred from Infrared Spectroscopy [PDF]
, 2008 We review the composition of Jupiter-family comet dust as inferred from infrared spectroscopy. We find that Jupiter-family comets have 10 micron silicate emission features with fluxes roughly 20-25% over the dust continuum (emission strength 1.20-1.25), similar to the weakest silicate features in Oort Cloud comets.

arXiv, 2020 Recent publications discuss the size of chemical rockets for long-distance travel, to be launched from a planet. Here I point out that such a rocket cannot be tall and slim but will be short and fat.
