Dart-7.jpegDimorphos142 visiteDART's last complete image of Dimorphos before impact. It was taken when the spacecraft was about 7 miles (approx. 12 Km) from the asteroid and 2" before impact. Dimorphos was about 6,8 MMs (such as about 11 MKM) from Earth at the time of DART's impact.MareKromium

Didymos_and_Dimorphos.jpeg65803 Didymos and 65803-1 Dimorphos98 visiteAsteroid Didymos and its small moonlet Dimorphos make up what’s called a "Binary Asteroid System" – meaning the small moon (Dimorphos) orbits the larger body (Didymos).
The two asteroids are not a threat to Earth, but because they do pass relatively close to Earth, they were chosen as the target for NASA’s Double Asteroid Redirection Test (DART) mission – the agency's first mission to test planetary defense technology. This technology could one day be used to deflect hazardous asteroids on a collision course with Earth.MareKromium

EROS-G-TouchDown.jpg433 Eros: 4 years after the "touch-down"!55 visiteCaption da "NASA - Picture of the Day" del 12.02.2005:"On 12 February, 2001, the NEAR-Shoemaker spacecraft gently touched-down on the the surface of Eros - the first ever landing on an asteroid. During the descent, the spacecraft's camera recorded successive images of the diminutive world's surface, revealing fractured boulders, dust filled craters, and a mysterious collapsed channel. The last frame, seen in the above montage at the far left, was taken at a range of 128 meters. Expanded in the inset, it shows surface features a few centimeters across. Stereo experimenter Patrick Vantuyne, constructed this montage from the final images in the landing sequence, carefully identifying the overlapping areas in successive frames. Frames which overlap were taken by the spacecraft from slightly different viewpoints, allowing Vantuyne to construct close-up stereo images of the surface of asteroid 433 Eros".

EROS-PIA02492.jpgEros in true colors84 visiteAs the NEAR Shoemaker spacecraft descends into lower orbits around Eros, it continually returns higher spatial resolution images of the asteroid. The true color image at left was taken February 12, 2000, from a range of 1.748 Km and shows details only as small as 180 meters (590 feet) across. It was taken two days before orbit insertion, as part of an image sequence designed to provide moderate-resolution color mapping of Eros at a near-constant viewing geometry. The true color image inset at right was taken February 29 from a range of 283 Km and shows much smaller details only 27 meters (89 feet) across.
