Mars One, the Plan to Make a Reality Show on Mars, is Bankrupt

In 2012, Dutch entrepreneur Bas Lansdorp launched the world’s first private and crowdsourced-effort to create a permanent outpost on Mars. Known as Mars One, this organization was the focus of a lot of press since it’s inception, some of it good, most of it bad. While there were many who called the organization’s plan a “suicide mission” or a “scam”, others invested their time, energy, and expertise to help make it happen.

In addition, thousands of volunteers signed on for the adventure, willing to risk life and limb to become part of the first one-way trip to the Red Planet. Unfortunately, we may never get to know if Bas Lansdorp’s plan for colonizing Mars was feasible or even sincere. According to a recent declaration by a Swiss Court, Mars One Ventures (the for-profit arm of Mars One) is now bankrupt.

InSight has Placed its Heat Probe on the Martian Surface. The Next Step is to Jackhammer Down 5 Meters and Hope it Doesn’t Encounter a Large Rock

NASA’s InSight lander has finally placed its heat probe on the surface of Mars. The Heat Flow and Physical Properties Package (HP³) was deployed on February 12th, about one meter away from SEIS, the landers seismometer. Soon it’ll start hammering its way into the Martian soil.

A glaciologist has discovered another enormous impact crater under more than a mile of ice in Greenland. This is on the heels of the November 2019 discovery of an impact crater in the same area under the Hiawatha Glacier. The November discovery was the first-ever crater found under ice on Earth.

Like Earth, Uranus and Neptune have season and experience changes in weather patterns as a result. But unlike Earth, the seasons on these planets last for years rather than months, and weather patterns occur on a scale that is unimaginable by Earth standards. A good example is the storms that have been observed in Neptune and Uranus’ atmosphere, which include Neptune’s famous Great Dark Spot.

During its yearly routine of monitoring Uranus and Neptune, NASA’s Hubble Space Telescope (HST) recently provided updated observations of both planets’ weather patterns. In addition to spotting a new and mysterious storm on Neptune, Hubble provided a fresh look at a long-lived storm around Uranus’ north pole. These observations are part of Hubble‘s long-term mission to improve our understanding of the outer planets.

There’s Evidence that Mars is Still Volcanically Active

A new study shows that Mars may very well be volcanically active. Nobody’s seen direct evidence of volcanism; no eruptions or magma or anything like that. Rather, the proof is in the water.

Want to Move to Mars? A Round-Trip Ticket Will Only Cost $100,000 According to Elon Musk

Elon Musk just suggested that the price for a trip to Mars and back could be as low as $100,000. He added the qualifier that the price depends on volume. So it looks like the price is anything but astronomical.

Here’s a Clever idea. Build Moon Bases in Craters and then Fill them in with Lunar Regolith

In the coming decades, multiple space agencies are planning to send astronauts to the lunar surface. More than that, between the European Space Agency (ESA), the China National Space Administration (CNSA) and Roscomos, there are multiple plans to construct permanent outposts on the Moon. Perhaps the best-known of these is the ESA’s plan to build an International Lunar Village,

As a spiritual successor to the International Space Station (ISS), this village would serve as a base for teams of astronauts to conduct vital research and experiments. In recent years, some very interesting proposals have been presented as part of this plan, the latest of which comes from the ESA’s European Astronaut Center (EAC), where a student team has developed a proposal for a sustainable lunar habitat.

Thanks to Gaia, We Now Know Exactly When We’ll be Colliding with Andromeda

Astronomers have known for some time that the Milky Way and the Andromeda galaxies will collide on some future date. The best guess for that rendezvous has been about 3.75 billion years from now. But now a new study based on Data Release 2 from the ESA’s Gaia mission is bringing some clarity to this future collision.

On December 31st, 2018, NASA’s New Horizons mission made history by being the first spacecraft to rendezvous with the Kuiper Belt Object (KBO) named Ultima Thule (2014 MU69). This came roughly two and a half years after New Horizons became the first mission in history to conduct a flyby of Pluto. This latest encounter led to some stunning images of the KBO as the spacecraft made it’s approach.

But of course, these were not the last images New Horizons was going to capture of this object. While making its flyby of Ultima Thule on New Year’s Day, the spacecraft took a number of images that revealed something very interesting about Ultima Thule’s shape. Rather than consisting of two spheres that are joined together, Ultima Thule is actually made up of two segments – one that looks like a pancake, the other a walnut.
