Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Lunar Trailblazer is a smallsat mission launched on 27 February 2025 as a secondary payload with the Intuitive Machines IM‐2 mission. After insertion into a near‐polar circular orbit around the Moon, the mission's goal was to search and characterize lunar water, primarily looking for ice in permanently shadowed craters and water bound in ...

Gaia: The Astrometry Revolution [PDF]

open access: yes, 2016
The power of micro-arcsecond (μas) astrometry is about to be unleashed. ESA's Gaia mission, now headed towards the end of the first year of routine science operations, will soon fulfil its promise for revolutionary science in countless aspects of ...

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Discovery of Hundreds of Main-belt Asteroids with Synthetic Tracking of WISE Data

open access: yesThe Planetary Science Journal
We analyze 1.5 million W3 Wide-field Infrared Survey Explorer (WISE) images acquired between 2010 January 7 and 2010 August 6 with the SALTAD synthetic tracking package to report astrometry of previously known and unknown main belt asteroids. We consider

COMMISSION 8: ASTROMETRY [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
Gaia is continuing well with its development and construction and is expected to achieve parallax accuracies of about 10 to 300 μas for 6 to 20 mag. It is scheduled to launch in 2013. The ICRF2 was adopted by the IAU in 2009 as the new fundamental celestial reference frame.

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Halometry from astrometry [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2018
Halometry---mapping out the spectrum, location, and kinematics of nonluminous structures inside the Galactic halo---can be realized via variable weak gravitational lensing of the apparent motions of stars and other luminous background sources. Modern astrometric surveys provide unprecedented positional precision along with a leap in the number of ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Commission 24: Photographic Astrometry: (Astrometrie Photographique) [PDF]

open access: yesTransactions of the International Astronomical Union, 2000
The scope of scientific interests of about 130 Commission members is much more complex than one may expect from the title of the commission. Besides traditional topics like the compilation of astrometric catalogues and the construction of an inertial reference system, more and more investigations performed by our members have been dedicated to the ...

Radial Velocity Monitoring and Analysis of Gaia Astrometry of Selected Intermediate Mass Stars to Constrain Their Multiplicity Status

open access: yesAstronomische Nachrichten, Volume 347, Issue 1, January 2026.
ABSTRACT We present new radial velocity measurements of 13 selected intermediate mass stars (2–6 M⊙). The measurements were performed between 29 April and 6 September 2024 at the University Observatory Jena using the échelle spectrograph FLECHAS. The radial velocity of eight stars was found to be constant during our spectroscopic monitoring, namely: 17
