NASA's Voyager Twins Used a Rare Planetary Alignment to Tour the Giant Planets

·4 views

In 1977 NASA launched the twin spacecraft Voyager 1 and Voyager 2. The missions took advantage of a planetary alignment that occurs roughly once every 175 years, involving Jupiter, Saturn, Uranus, and Neptune. By using six gravity assists between the planets, the Grand Tour enabled close-up observations of the gas and ice giants. The flybys also captured images and data on several of their moons. The article is part of NASA's November night sky notes series.

Map Pinpoints 13 Possible Mars Origins for Ancient Meteorite Teghaza 001

A new global map of Mars marks 13 locations whose mineralogy and chemistry resemble those of Teghaza 001, one of the oldest Martian meteorites ever recovered on Earth. Scientists acknowledge they can never be certain where a Martian meteorite began. Still, the meteorite carries chemical clues that connect it to highlands in Mars's southern hemisphere. The map is intended to narrow the search for the rock's likely source region. The findings help researchers better understand the planet's ancient geology.

Ancient Martian Meteorite Teghaza 001 Used to Date Its Rock

A slice of Teghaza 001, among the oldest Martian meteorites ever recovered on Earth, was used by scientists to determine the age of the rock. Reflected-light images of the sample act as a road map, guiding researchers to the minerals they want to study. These images help direct analysis by different instruments. The accompanying figures show the same view with annotations marking points of interest. The article is a NASA description of the sample and the imaging methods used to study it.
