Dart-7.jpegDimorphos146 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

EROS-PIA02905-0.jpgEros (the BIG Pseudo-Anomaly)140 visiteThis image of Eros, taken from the NEAR Shoemaker spacecraft on May 1, 2000, is among the first to be returned from "low orbit." Between May and August, the spacecraft orbited at altitudes near 50 Km or less. This will be the prime period of activity for some of the spacecraft's science instruments. The X-ray / gamma-ray spectrometer will build up maps of chemical abundances, while the laser rangefinder measures the shape of Eros to within meters (a few feet). At the same time the magnetometer will watch for indications of Eros' magnetic field and the near-infrared spectrometer will map rock types. The imager will take pictures of the entire surface of Eros that capture features as small as 4 meters (13 feet) across. This particular image, taken from an orbital altitude of 53 Km, shows a scene about 1.8 Km across. Numerous craters and boulders as small as 8 meters (26 feet) across dot the landscape. The large, rectangular boulder at the upper right is about 45 meters across.

Comet_Borisov_-_Still.pngFrom far away: Comet Borisov138 visiteDa un altro Sistema, dallo Spazio Interstellare, da "altrove".... La "Cometa" Borisov attraverserà il nostro Sistema Solare così come una Rondine attraversa il nostro campo visivo in un luminoso giorno di Primavera.
Da dove viene? Dove va?

EROS-PIA02927.jpgEros' Boulders124 visiteNEAR Shoemaker images have shown many large boulders on Eros' surface, but seldom are the boulders as big and as close as the ones in this image taken on June 20, 2000, from an altitude of 51 Km. Nestled within the 700-meter (2300-foot) diameter crater at the center of the picture are four particularly large rocks whose tops protrude out from the shadowed crater interior and into sunlight. The center boulder, the largest, is about 100 meters (330 feet) across. The whole scene is approximately 1.9 Km across.

Tempel1-ZZ-ZJ-Stardust_1024-PIA13867.jpgComet Tempel-1 from Stardust NeXT Spacecraft (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 122 visiteCaption NASA:"At the time of the encounter, comet Tempel-1 was approx. 335 MKM (about 208 MMs) away from Earth.
Tempel-1 is oblong in shape and has an average diameter of about 6 Km (approx. 4 miles). Stardust-NExT is an extended mission for the comet chaser, which previously flew past comet Wild 2 and returned some samples from its Coma to Earth.
During this latest encounter, the Spacecraft took images of the Comet's Surface and observed changes that occurred since a NASA Spacecraft last visited it (NASA's Deep Impact Spacecraft had an encounter with Tempel-1 in July 2005).
Stardust-NExT is a low-cost mission that is expanding the investigation of comet Tempel-1 initiated by the Deep Impact Spacecraft.
The mission is managed by the Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, Calif., for NASA's Science Mission Directorate in Washington. Lockheed Martin Space Systems in Denver built the Spacecraft and manages day-to-day mission operations".MareKromium
