چکیده

Measurements from the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker Laser Rangefinder (NLR) indicate that asteroid 433 Eros is a consolidated body with a complex shape dominated by collisions. The offset between the asteroid's center of mass and center of figure indicates a small deviation from a homogeneous internal structure that is most simply explained by variations in mechanical structure. Regional-scale relief and slope distributions show evidence for control of topography by a competent substrate. Impact crater morphology is influenced by both gravity and structural control. Small-scale topography reveals ridges and grooves that may be generated by impact-related fracturing.

Laser altimetry of small-scale features on 433 Eros from NEAR-Shoemaker.

During the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker's low-altitude flyover of asteroid 433 Eros, observations by the NEAR Laser Rangefinder (NLR) have helped to characterize small-scale surface features. On scales from meters to hundreds of meters, the surface has a fractal structure with roughness dominated by blocks, structural features, and walls of small craters. This fractal structu...

NEAR Laser Rangefinder: A Tool for the Mapping and Topologic Study of Asteroid 433 Eros

n 1999, after a 3-year transit through space, the Near Earth Asteroid Rendezvous (NEAR) spacecraft will place a scientific payload consisting of five instruments into a low-altitude orbit (≈35 km) about the asteroid 433 Eros for 1 year. One instrument, the NEAR Laser Rangefinder (NLR), will use infrared laser pulses to provide astrophysicists with precision altimetry data, measurements that wer...

In-Flight Calibration of the Near Earth AsteroidRendezvous Laser Rangefinder

The Near Earth Asteroid Rendezvous (NEAR) mission began a year-long rendezvous with 433 Eros on 14 February 2000. The NEAR Laser Rangefinder (NLR) will measure ranges from the spacecraft to the surface of Eros with a single shot accuracy of a few meters. The NLR topographic data, when combined with doppler tracking of the spacecraft, will enable determinations of the asteroid’s shape, mass, and...

The Laser Rangefinder on the near Earth Asteroid Rendezvous Spacecraft

In 1999, the Near Earth Asteroid Rendezvous (NEAR) mission will place a spacecraft with five facility instruments, including the NEAR Laser Rangefinder (NLR), into a low-altitude (-50 km) orbit about the asteroid 433 Eros. The NLR is a high-fidelity altimeter capable of 3 1.5cm resolution and c2-m accuracy, and will be operate-d continuously while at Eros. The NLR design is quite robust and is ...

Landing – Development of NEAR Shoemaker ’ s Controlled

On February 12, 2001, the NEAR Shoemaker spacecraft made its historic descent to the surface of the asteroid 433 Eros, becoming the first spacecraft to soft land on a small celestial body. Development of the final descent activity offered the NEAR team a difficult technical challenge as the spacecraft had been designed solely as a free flyer, not as a lander. The NEAR Shoemaker spacecraft rende...
