Space technology company Lunar Outpost has unveiled their new Lunar Prospector rover that will explore the surface of the Moon to search for and map resources. The Lunar Prospector is designed to drill for and analyze sub-surface samples. The first of the smallish robots was recently demonstrated on simulated Lunar regolith at the Colorado School of Mines.

Honey, Where’s the Space Sperm? It’s in Low-Earth Orbit, Dear

It’s always wise to be prepared for a disaster, but space sperm is taking it a little too far. Having things like food, water, and medicines on hand constitutes a reasonable level of preparation. But now one company wants to freeze your eggs and sperm in space.

Not all the Earth’s Water Came From Comets

This view of Earth’s horizon was taken by an Expedition 7 crewmember onboard the International Space Station, using a wide-angle lens while the Station was over the Pacific Ocean. A new study suggests that Earth's water didn't all come from comets, but likely also came from water-rich planetesimals. Credit: NASA

We have comets and asteroids to thank for Earth’s water, according to the most widely-held theory among scientists. But it’s not that cut-and-dried. It’s still a bit of a mystery, and a new study suggests that not all of Earth’s water was delivered to our planet that way.

Parker Solar Probe Became the Closest Thing We’ve Ever Sent to the Sun. And it’s Just Getting Started.

NASA’s Parker Solar Probe is now the closest object to the Sun that we’ve ever sent into space. On Oct. 29, 2018, at about 1:04 p.m. EDT, NASA’s probe broke the old record for the close-to-Sun distance of 42.73 million km (26.55 million miles). That record was held by the German-American Helios 2 spacecraft in 1976. And the probe will keep getting closer to the Sun.

There’s a Funny Cloud on Mars, Perched Right at the Arsia Mons Volcano. Don’t Get Too Excited, Though, it’s not an Eruption

The ESA’s Mars Express orbiter has spotted a funny cloud on Mars, right near the Arsia Mons Volcano. At first glance it looks like a plume coming out of the volcano. But it’s formation is not related to any internal activity in this long-dead volcano. It’s a cloud of water ice known as an orographic or lee cloud.

The cloud isn’t linked to any volcanic activity, but its formation is associated with the form and altitude of Arsia Mons. Arsia Mons is a dormant volcano, with scientists putting its last eruptive activity at 10 mya. This isn’t the first time this type of cloud has been seen hovering around Arsia Mons.

What would it be like to be onboard the Cassini orbiter as it made its way around Jupiter and Saturn and their moons? Pretty cool. Now a new video made from Cassini images pieces together parts of that stately journey.

The Path that MASCOT Took Across Asteroid Ryugu During its 17 Hours of Life

The tiny hopping-robot MASCOT completed its 17 hour mission on the asteroid Ryugu in early October. Now the German Aerospace Center (DLR) has released an image of MASCOT’s path across the asteroid. Surprised by what MASCOT found on the surface, they’ve named the landing spot “Alice’s Wonderland.”

Even Ganymede is Showing Tectonic Activity. We’re Going to Need Another Icy Moon Orbiter

Ganymede was shaped by pronounced periods of tectonic activity in the past, according to a new paper. It’s no longer active and its surface is more-or-less frozen in place now. But this discovery opens the door to better planning for future missions to Jupiter’s other frozen moon Europa. Unlike Ganymede, Europa is still tectonically active, and understanding past geological activity on Ganymede helps us understand present-day Europa.

The Milky Way Could Be Spreading Life From Star to Star

For almost two centuries, scientists have theorized that life may be distributed throughout the Universe by meteoroids, asteroids, planetoids, and other astronomical objects. This theory, known as Panspermia, is based on the idea that microorganisms and the chemical precursors of life are able to survive being transported from one star system to the next.

Expanding on this theory, a team of researchers from the Harvard Smithsonian Center for Astrophysics (CfA) conducted a study that considered whether panspermia could be possible on a galactic scale. According to the model they created, they determined that the entire Milky Way (and even other galaxies) could be exchanging the components necessary for life.

Ceres Rolled Over at Some Point in the Past

In 2007, the Dawn mission launched from Earth and began making its way towards two historic rendezvous in the Main Asteroid Belt. The purpose of this mission was to learn more about the history of the early Solar System by studying the two largest protoplanets in the Main Belt – Ceres and Vesta – which have remained intact since their formation.

In 2015, the Dawn mission arrived in orbit around Ceres and began sending back data that has shed light on the protoplanet’s surface, composition and interior structure. Based on mission data, Pasquale Tricarico – the senior scientist at the Planetary Science Institute (PSI) – has also determined that the Ceres also experienced an indirect polar reorientation in the past, where its pole rolled approximately 36° off-axis.
