Credit: Ricardo Arevalo Topics: Astrobiology, Astronautics, Biology, Laser, NASA, Planetary Science, Space Exploration As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving, and accurate analytical tools have become increasingly critical—especially as the hunt for extraterrestrial life and habitable planets or moons continues. A University ofContinue reading “Life Detector…”
At Horizon’s Edge…
An artist’s concept of New Horizons during the spacecraft’s planned encounter with Pluto and its moon Charon. The craft’s miniature cameras, radio science experiments, ultraviolet and infrared spectrometers, and space plasma experiments would characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto’s atmosphere in detail.

Topics: Astronomy, Astrophysics, NASA, Planetary Science WASHINGTON, Sept 15 (Reuters) – Call it the case of the missing moon. Scientists using data obtained by NASA’s Cassini spacecraft and computer simulations said on Thursday the destruction of a large moon that strayed too close to Saturn would account both for the birth of the gas giantContinue reading “Death of Chrysalis…”

Topics: Astrophysics, Planetary Science, SETI, Space Exploration Even as a child, before he devoted his life to the search for extraterrestrial life, Frank Drake wondered whether Earth was alone in its ability to harbor life. He wasn’t the first or the only one to wonder. There’s a reason so many are fascinated by the question:Continue reading “Roaming Goldilocks…”
Ganymede…
Topics: Astronomy, Astrophysics, NASA, Planetary Science, Space Exploration Ganymede, get ready for your close-up. No probe has gotten a good view of Jupiter’s largest moon since 2000, when NASA’s Galileo spacecraft swung past the strange world, which is the largest moon in the whole solar system. But on Monday (June 7), at 1:35 p.m. EDT (1735 GMT),Continue reading “Ganymede…”
