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.

Super Earth Planet Found Around One of the Closest Stars to us. But it’s Probably a Terrible Place to Live

The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. Data from a worldwide array of telescopes, including ESO’s planet-hunting HARPS instrument, have revealed this frozen, dimly lit world. The newly discovered planet is the second-closest known exoplanet to the Earth and orbits the fastest moving star in the night sky. This image shows an artist’s impression of the planet’s surface.

In the course of searching for extra-solar planets, some very interesting finds have been made. Some of them have even occurred within our own galactic neighborhood. Just two years ago, astronomers from the Red Dots and CARMENES campaigns announced the discovery of Proxima b, a rocky planet that orbits within the habitable zone of our nearest stellar neighbor – Proxima Centauri.

This rocky world, which may be habitable, remains the closest exoplanet ever discovered to our Solar System. A few days ago (on Nov. 14th), Red Dots and CARMENES announced another find: a rocky planet orbiting Barnard’s star, which is just 6 light years from Earth. This planet, Barnard’s Star b, is now the second closest exoplanet to our Solar System, and the closest planet to orbit a single star.

You just never know when it comes to comets. Here it is mid-November, and we’d thought we had finished up writing about bright comets for 2018. That was until this past weekend, when a flurry of messages flashed across the Yahoo! Comets mailing list hinting that a new, possibly bright comet had been discovered. Come Monday morning November 12th, long period Comet C/2018 V1 Machholz-Fujikawa-Iwamoto was formally added to the International Astronomical Union’s Minor Planet list.

SpaceX Gives More Details on how their Starlink Internet Service Will Work. Less Satellites, Lower Orbit, Shorter Transmission times, Shorter Lifespans

For years, Elon Musk has talked about his plans to provide broadband internet access to the world using a constellation of satellites. Known as Starlink, this constellation was originally going to of nearly 12,000 low-cost satellites providing a terabit internet service. The first batch of these satellites is scheduled to launch in June of 2019, with the full constellation being deployed by the mid-2020s.

While the bare bones of this plan have been public knowledge for some time, Musk and the company he founded to reinvigorate space exploration have been somewhat scant on the details. But thanks to a simulation created by Prof. Mark Handley of University College London, the world may finally get an idea of what Starlink might look like.

Going 1 Million Miles per Hour With Advanced Propulsion

Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects.

NASA Institute for Advanced Concepts (NIAC) is funding two high potential concepts. New ion drives could have ten times better in terms of ISP and power levels ten thousand times higher. Antimatter propulsion and multi-megawatt ion drives are being developed.

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.

Scientists are Using Artificial Intelligence to See Inside Stars Using Sound Waves

NASA's Solar Dynamics Observatory has captured images of a growing dark region on the surface of the Sun. Called a coronal hole, it produces high-speed solar winds that can disrupt satellite communications. Image: Solar Dynamics Observatory / NASA

How in the world could you possibly look inside a star? You could break out the scalpels and other tools of the surgical trade, but good luck getting within a few million kilometers of the surface before your skin melts off. The stars of our universe hide their secrets very well, but astronomers can outmatch their cleverness and have found ways to peer into their hearts using, of all things, sound waves.

ARCHIMEDES: Digging into the ice on Europa with lasers

The fascinating surface of Jupiter’s icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA's Galileo spacecraft in the late 1990s.

Ever since the Pioneer and Voyager probes passed through the Jovian system in the 1970s, NASA and other space agencies have dreamed of one-day sending a mission to Europa. Beyond Earth, it is considered one of the most promising candidates for finding life, which could exist in the subsurface ocean that lies beneath the moon’s icy crust.

One of these concepts is known as the Cool High Impact Method for Exploring Down into Europan Subsurface (ARCHIMEDES), a proposed direct-laser penetrator that will use a laser light carried by an optical fiber tether to penetrate Europa’s icy crust. This mission could provide future missions with access to the ocean that exists beneath Europa’s surface and enable the search for life there.

Gaia Spots an Enormous Ghost Galaxy Right Next Door that’s Being Dismantled by the Milky Way

Astronomers combing through data from the ESA’s Gaia spacecraft have discovered what they’re calling a ghost galaxy. The galaxy, named Antlia 2 (Ant 2) is an extremely low-density dwarf galaxy that was formed in the early days of the universe. And it is being stripped of its mass by the tidal forces of the Milky Way.
