The sunshade for the NEO Surveyor mission is ready for its day in the sun! 😎 NASA's Near-Earth Object (NEO) Surveyor will hunt for potentially hazardous asteroids and comets that cross Earth’s path. ½

We’ve known since the Apollo missions that dust can present challenges for explorers on other worlds. Now, scientists are using instruments on the Perseverance rover to understand the risks of dust on Mars and find clues about how to protect future crews on the Red Planet. ½

Have you put up your Halloween decor? The night sky will add the finishing touch. 🌕 October’s full moon, named the Hunter’s Moon, will rise on the night of Oct. 26. Its name comes from the seasonal practice of hunters relying on bright moonlight.
A mostly-full Moon appears deep yellow in contrast with the blue night sky around it. A dark flock of birds flies just below it. The tops of buildings and trees peek out from the bottom of the photo.

The Moon has impeccable timing. October's full Moon rises tonight, bringing a little moonlit magic to the start of Halloween week. The Moon reaches peak illumination at 12:12am ET (0412 UTC) on Oct. 26. Don't forget to look up!

On Oct. 24, 2001, NASA's Mars Odyssey spacecraft slipped into orbit around the Red Planet. 25 years later, it's still conducting science and relaying messages from the rovers, making it the longest-operating orbiter ever at a planet beyond Earth.  ½

When the Apollo 8 astronauts became the first to observe the Moon up close, NASA gathered insights from what they saw into a special publication. The Artemis II preliminary lunar science report is a continuation of this story of data and science made possible by NASA's missions to the Moon. 🔗 go.nasa.gov/4igLKBj
Cover of the "Analysis of Apollo 8 Photography and Visual Observations" special report published in 1969. It features the Earthrise image taken by the Apollo 8 crew.

NASA's Cassini spacecraft lifted off 29 years ago to begin its long voyage to Saturn. For 13 years, Cassini orbited Saturn, revealing unexpected features of the planet, its rings, and its icy moons, and expanding our understanding of the kinds of worlds where life might exist.

Have no fear of Phobos! Mars has two moons, Phobos and Deimos ("fear" and "terror"). On Oct. 19, @JAXA_en will launch the MMX mission to explore them and return a sample of Phobos! A teleconference at 4 p.m. EDT today will preview NASA's contributions: go.nasa.gov/4B2qNBI

The first crewed Apollo mission lifts off! Wally Schirra, Walt Cunningham, and Donn Eisele became the first 3 astronauts to be launched on a Saturn rocket 58 years ago today. This 11-day mission in Earth orbit was an important test of the Apollo command and service module. Three months later, it would take NASA astronauts around the Moon.
Apollo 7 lifts off from Cape Kennedy Launch Complex 34 at 11:03 A.M., EDT on Oct 11, 1968. The astronauts aboard are Astronauts Walter M. Schirra,Jr. Commander; Donn F. Eisele, Command Module Pilot; and Walter Cunningham, Lunar Module Pilot.

Our @NASAJPL team brought a preview of Mars exploration to Huntington Beach with their SkyFall demo. Building on Ingenuity, SkyFall will deploy three helicopters in midair to Mars and use ground penetrating radar to search for subsurface ice. In addition to other scientific instruments, this effort will show how we could potentially identify landing sites for future Mars missions.  Fission powered spacecraft and helicopters exploring another planet to help prepare for Americans to follow. Hard not to get excited about this mission.
