Enceladus is blasting water into space from the jets at its southern pole. This makes it the ideal place to send a dedicated mission, flying the spacecraft through the plumes with life-detection instruments s. A new study suggests that a spacecraft must proceed carefully through the plumes, keeping its speed below 4.2 km/second (2,236 miles per hour). Using a specialized, custom-built aerosol impact spectrometer at these speeds will allow fragile amino acids to be captured by the spacecraft’s sample collector. Any faster, they’ll shatter, providing inclusive results.

SpaceX, US Space Force set to launch secretive X-37B space plane on Dec. 10
Final preparations are underway for a Dec. 10 launch opportunity, which will mark the first time the X-37B has lifted off atop SpaceX's powerful Falcon Heavy rocket.
OSIRIS-REx Failed to Deploy its Drogue Chute Properly. Now NASA has Figured out Why
On September 24, 2023, NASA’s OSIRIS-REx mission returned a precious sample of rocky material from asteroid Bennu to Earth. The capsule landed safely under its main parachute, but it arrived more than a minute early. The cause: a small drogue parachute, designed to slow the spacecraft down prior to the main chute’s deployment, failed to open. After an investigation into the mishap, NASA believes they have determined the cause of the (happily non-catastrophic) failure.
Scientists study violent 'superflares' on stars thousands of times brighter than the sun
Scientists have used solar flares from the sun to determine the physics driving powerful and violent 'superflares' on massive stellar bodies that are up to 10,000 times brighter than our star.
Dark Halos and Warped Disks
Galaxies are embedded within halos of dark matter, and the tilt of those halos can affect the galaxy's stellar halo and stellar disk.

Private cargo spacecraft named for shuttle-era astronaut who died of plane crash injuries
NASA astronaut Patricia Hilliard 'Patty' Robertson, who died from injuries sustained in a plane crash, is Northrop Grumman's chosen namesake for its first Cygnus to launch atop a SpaceX rocket.
Ethereal halo of light around full moon spotted during recent SpaceX rocket launch
An eerily-perfect ring of light was spotted around the full moon in Florida during the recent launch of a SpaceX Falcon 9 rocket, creating a stunning new photo.
NOAA's older Earth-watching satellites get new 'extended life'
NOAA has plans to add extra years to the lifespan of their fleet of older polar orbiting satellites by controlling them through using an Internet cloud-based system.
Signs of life shooting from Saturn's moon Enceladus would be detectable by spacecraft, scientists say
Scientists believe possible amino acids in Enceladus' subsurface ocean can indeed be detected by spacecraft.

NASA astronaut will celebrate Hanukkah in space with felt menorah
NASA International Space Station astronaut Jasmin Moghbeli will pin candles on a felt menorah to honor Hanukkah, the Jewish festival that begins Dec. 7.
Minding the gap on tropical forest carbon
Tropical forests are clearly critical to Earth’s climate system, but understanding exactly how much carbon they absorb from the atmosphere, store and release is tricky to calculate, not least because measuring and reporting methods vary. With these measurements paramount for nations assessing the action they are taking to combat the climate crisis, new research shows how differences in estimates of carbon flux associated with human activity can be reconciled.
In 1872, a Solar Storm Hit the Earth Generating Auroras from the Tropics to the Poles
Imagine a solar storm generating auroral displays across the entire sky. No, we haven’t quite seen them that strong in the current solar cycle. But, back in February 1872, people around the world reported seeing brilliant northern and southern lights. The culprit? A medium-sized sunspot group that unleased a torrent of charged particles in a coronal mass ejection directed toward Earth.
For its Final Trick, Chandrayaan-3 Brings its Propulsion Module to Earth Orbit
On August 23, ISRO’s Vikram lander detached from its propulsion module and made a soft landing near the Moon’s south pole region. The lander then deployed its Pragyan rover, and for two weeks the endearing little solar-powered rover performed marvelously, detecting water ice and characterizing the makeup of the lunar regolith before succumbing to the darkness and cold of the lunar night.
India returns Chandrayaan-3 moon mission's propulsion module to Earth orbit
The spacecraft that ferried India's Chandrayaan-3 lander-rover duo to the moon has returned home to Earth orbit.
ESA’s Ariel Mission is Approved to Begin Construction
We’re about to learn a lot more about exoplanets. The ESA has just approved the construction of its Ariel mission, which will give us our first large survey of exoplanet atmospheres. The space telescope will help us answer fundamental questions about how planets form and evolve.
NASA marks 25th anniversary of ISS with call to crew on space station
Twenty-five years ago, Bob Cabana was at space shuttle Endeavour's controls when he fired thrusters to dock a U.S.-built node with a Russian module, giving birth to the International Space Station.
Satellites watch as Japan's new volcanic island continues to grow (image)
