Voyager 1 has entered a new region between our solar system and interstellar space, which scientists are calling the stagnation region. In the stagnation region, the wind of charged particles streaming out from our sun has slowed and turned inward for the first time, our solar system's magnetic field has piled up and higher-energy particles from inside our solar system appear to be leaking out into interstellar space.
Scientists hope to use a balloon such as this one, 9 meters in diameter, to study the atmosphere of Venus from below its clouds. A helium-filled Teflon balloon could stay high enough above the ground (at an altitude of about 56 kilometers) to avoid cooking at Venus' high surface temperatures, and would be resistant to corrosion from the sulfuric acid in Venus' clouds.
Lunar Reconnaissance Orbiter view of Apollo 14 landing site. Tracks from a cart used to carry ALSEP equipment from the lunar module Antares are visible in this photo. The inset shows a picture taken from the ALSEP site, looking back at the Antares.
The descent module of the lunar module Challenger is seen in this image, halfway between the ALSEP site and the final resting spot of the lunar rover. In the inset photo, the rover is also at its final stop, with the Challenger seen in the background.
