as16-107-17435.jpgAS 16-107-17435 - Orion's portrait54 visiteCaption NASA:"Rightward of 17434. This is a good portrait of the LM (Orion), the MESA, the SEQ Bay, the Rover. John (Young) is beyond the Rover, collecting a rock sample".MareKromium

ZZ-New_Horizons-03.jpgOn the way to Pluto: beyond Jupiter (4)54 visiteCaption NASA:"This image shows New Horizons' Current Position (end of February, 2007). The green segment of the line shows where New Horizons has traveled since launch; the red indicates the spacecraft's path toward Jupiter, Pluto and beyond. Positions of stars with magnitude 12 or brighter are shown from this perspective, which is above the Sun and "north" of Earth's orbit.

AU -> The graphics on these pages note New Horizons' distance from Earth, Jupiter and Pluto in AU, or Astronomical Units. One AU is the average distance between the Sun and Earth, about 93 MMs or 149,6 MKM.

HV -> The Current Position graphic also notes the spacecraft's Heliocentric Velocity - HV, such as its speed with respect to the Sun - in kilometers per second.
One kilometer per second is equivalent to 0,62 miles per second, or 2237 miles per hour".

ZZ-New_Horizons-01.jpgOn the way to Pluto: the passing of Mars (2)54 visiteCaption NASA:"New Horizons' trailblazing journey to the Solar System's outermost frontier took it past the orbit of Mars at 6 a.m. EDT (1000 UTC) on April 7, 2006 - 78 days after the spacecraft launched.

At the time, because of Mars' position in its orbit, New Horizons was actually closer to Earth than to Mars - just 93,5 MKM (58,1 MMs) from home, compared to 299 MKM (186 MMs) from the Red Planet. Speeding away from the Sun at 21 Km (about 13 miles) per second, the spacecraft crossed Mars' path some 243 MKM (about 151 MMs) from the Sun - close to the farthest point in Mars' elliptical 687-day orbit".

ZZ-New_Horizons-00.jpgOn the way to Pluto: the passing of the Moon (1)54 visiteCaption NASA:"The first body New Horizons passed after launch was our own Moon, just 8 hours and 35' after liftoff on Jan. 19, 2006. New Horizons reached the closest distance to the Moon before crossing lunar orbit".

Saturn-PIA08361.jpgThe Ring-World in natural colors54 visiteCaption NASA:"Our robotic emissary, flying high above Saturn, captured this view of an alien copper-colored Ring-World. The overexposed planet has deliberately been removed to show the unlit Rings alone, seen from an elevation of 60°, the highest Cassini has yet attained.
The view is a mosaic of 27 images -- nine separate sets of red, green and blue images -- taken over the course of about 45', as Cassini scanned across the entire main Ring System. The Planet's shadow carves a dark swath across the Ring-Plane at the right.

Moons visible in this image: Epimetheus, at the 1 o'clock position; Pandora, at the 5 o'clock position and Janus, at the 10 o'clock position.

Bright clumps of material in the narrow F-Ring moved in their orbits between each of the color exposures, creating a chromatic misalignment that provides some sense of the continuous motion in the Ring System.
Radially extending lens flare artifacts, which result from light being scattered within the camera optics, are present in the view.

The images in this natural-color view were obtained with the Cassini spacecraft wide-angle camera on Jan. 21, 2007, at a distance of approx. 1,6 MKM (1 MMs) from Saturn. Image scale is 90 roughly Km (about 56 miles) per pixel".
