Crew Members on the International Space Station Celebrate Halloween in Orbit

·2 views

No trick-or-treaters visit the International Space Station, but its crew still embraces the Halloween spirit. Astronauts dress up individually or together in costumes that range from spooky to scary, though always imaginative. Many of the costumes are built from materials already available on board the orbiting laboratory. The tradition shows how the crew keeps morale and creativity alive while living far above Earth.

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.

NASA-Funded Study Dates a Rose-Colored Sahara Meteorite as Ancient Martian Rock

A rose-colored meteorite discovered in the Sahara Desert in 2022 initially had an unknown origin and age. NASA-funded scientists later dated its minerals and found that the roughly 800-gram rock came from Mars. Its formation more than 4.1 billion years ago places it among the oldest known Martian meteorites. The findings help researchers understand the planet's earliest geological history. The study underscores how desert finds can yield significant insights into the Red Planet.
