At a slow pace, the Moon is moving away from the Earth and the Earth is rotating more slowly around its axis. To say something about these changes in the distant past, geologists use information stored in rocks and fossils. But the further back in time they look, the more difficult it becomes to retrieve this information.

We have now discovered 30 039 near-Earth asteroids in the Solar System - rocky bodies orbiting the Sun on a path that brings them close to Earth's orbit. The majority of these were discovered in the last decade, showing how our ability to detect potentially risky asteroids is rapidly improving.

This morning's planning kicked off with great news! Our Sol 3620 SAM data of the Canaima drill sample was interesting enough to proceed with planning a Gas Chromatograph Mass Spectrometry (GCMS) experiment. This type of activity is one of SAM's specialties and can help characterize the chemistry of the rock we're parked in front of, including the presence of compounds essential to life as we kno NASA confirms DART impact changed asteroid's motion in space

Analysis of data obtained over the past two weeks by NASA's Double Asteroid Redirection Test (DART) investigation team shows the spacecraft's kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid's orbit. This marks humanity's first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology.

The cocktail of chemicals that make up the frozen surfaces on two of Jupiter's largest moons are revealed in the most detailed images ever taken of them by a telescope on Earth.
Planetary scientists from the University of Leicester's School of Physics and Astronomy have unveiled new images of Europa and Ganymede, two future destinations for exciting new missions to the Jovian system. NASA study suggests shallow lakes in Europa's icy crust could erupt

New research makes hypotheses that NASA's Europa Clipper can test: Any plumes or volcanic activity at the Jovian moon's surface are caused by shallow lakes in its icy crust.
In the search for life beyond Earth, subsurface bodies of water in our outer solar system are some of the most important targets. That's why NASA is sending the Europa Clipper spacecraft to Jupiter's moon Europa: There Lockheed Martin Space leader aims to speed things up

NASA's new November targets mean night launch for Artemis
Wednesday, 12 October 2022 15:59 Write a comment
If NASA gets to finally ignite its massive candle for the Artemis I moon mission, it's going to light up the night skies across Florida with three November launch dates that all fall after midnight targeted for liftoff from Kennedy Space Center.
NASA's first attempt to launch the Space Launch System rocket topped with the Orion space capsule falls on Monday, Nov. 14 with a 69-minute window that opens at 12:07 a.m. Two two-hour backup windows are available on Wednesday, Nov. 16 starting at 1:04 a.m. and Saturday, Nov. 19 starting at 1:45 a.m.
If it goes up, SLS with its 8.8 million pounds of thrust at liftoff would become the most powerful rocket to ever launch from Earth besting the Saturn V rockets from the Apollo missions.
Next month's full moon falls on Nov. 8, so the first attempt should feature a waning gibbous moon still rising high in the eastern sky at midnight. Florida's notorious afternoon showers during the summer will also be not as much of a concern in the overnight hours.
If it hits its first target, the uncrewed Orion capsule would make several orbits around the moon traveling farther from Earth than any other human-rated spacecraft before returning on Dec.
