Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Spin states of asteroids in the Eos collisional family

open access: yes, 2017
Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population.

Thermophysical Model of (269) Justitia—Main Belt Asteroid Possibly Implanted from Trans-Neptunian Region

open access: yesThe Planetary Science Journal
Asteroid Justitia is a special main-belt object, being an extremely red body with a steeper spectral slope than any other D-type asteroid. Conversely, its spectral and polarimetric properties resemble organics-rich Centaurs and trans-Neptunian objects ...

Determination of 1929 Asteroid Rotation Periods from WISE Data

open access: yesThe Planetary Science Journal, 2023
We used 22 μ m (W4) Wide-field Infrared Survey Explorer (WISE) observations of 4420 asteroids to analyze lightcurves, and determined spin period estimates for 1929 asteroids.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

First Results of the VLBI Experiment on Radar Location of the Asteroid 2012 DA14

open access: yesOpen Astronomy, 2013
An international VLBI experiment on radio location of the asteroid 2012 DA14 was organized on 2013 February 15–16, during its flyby close to Earth. The purpose of observations was to investigate and specify orbital parameters of the asteroid, as well as ...

Puzzling rotation of asteroid 288 Glauke [PDF]

open access: yesAstronomy & Astrophysics, 2003
Most asteroids rotate about their axis of maximum moment of inertia. However, for several small asteroids with very slow rotation rates, the damping time scale is expected to be longer than the age of the Solar System, implying that these objects may exhibit non-principal axis rotation.

Asteroid rotation excitation by subcatastrophic impacts [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2013
Photometric observations of asteroids show that some of them are in non-principal axis rotation state (free precession), called tumbling. Collisions between asteroids have been proposed as a possible asteroid rotation excitation mechanism. We simulated subcatastrophic collisions between asteroids of various physical and material parameters to find out ...

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

open access: yesSmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.
