The InSight lander has been on Mars for 213 Sols on its mission to understand the interior of the red planet. It’s armed with a seismometer, a temperature and wind sensor, and other instruments. But it’s primary instrument, arguably, is the Mole, or the Heat Flow and Physical Properties Package (HP3.) And the Mole has been stuck for a while now.

Dr. Avi Loeb Thinks the Government Should set its Sights on Big Ideas in Space Exploration

On July 20th, 2019, exactly 50 years will have passed since human beings first set foot on the Moon. To mark this anniversary, NASA will be hosting a number of events and exhibits and people from all around the world will be united in celebration and remembrance. Given that crewed lunar missions are scheduled to take place again soon, this anniversary also serves as a time to reflect on the lessons learned from the last “Moonshot”.

For one, the Moon Landing was the result of years of government-directed research and development that led to what is arguably the greatest achievement in human history. This achievement and the lessons it taught were underscored in a recent essay by two Harvard astrophysicists. In it, they recommend that the federal government continue to provide active leadership in the field of space research and exploration.

Who Wants to be a Trillionaire? Mission to Psyche Could Uncover Tons of Precious Metals!

It has been said that within the next quarter century, the world’s first trillionaires will emerge. It is also predicted that much of their wealth will stem from asteroid mining, a burgeoning space industry where minerals and volatile compounds will be harvested from Near-Earth Asteroids. This industry promises to flood the market with ample supplies of precious metals like gold, silver and platinum.

Beyond Earth, there’s the long-term prospect of the Main Asteroid Belt, which would provide even greater abundance. This is one of the reasons why NASA’s Psyche mission to explore the metal asteroid of the same name in the Main Belt has many people excited. While the exploration of this body could tell us much about the history of the Solar System, it could also be a source of riches someday.

The official announcement has been made. NASA is sending the Dragonfly, its rotary-winged flying robot, to Titan. We’ll have to control our excitement for a while, though. The launch date isn’t until 2026.

The Most Efficient Way to Explore the Entire Milky Way, Star by Star

It seems like the stuff of dreams, the idea that humanity will one day venture beyond the Solar System and become an interstellar species. Who knows? Given enough time and the right technology (and assuming there’s not some serious competition), we might even be able to colonize the entire Milky Way galaxy someday. And while this seems like a far-off prospect at best, it makes sense to contemplate what a process like this would entail.

That’s what a think tank from the ESA’s Advanced Concepts Team (ACT) managed to do recently. As part of the tenth annual Global Trajectory Optimization Competition (GOTC X), they created a simulation that showed how humanity could optimally colonize the Milky Way. This was in keeping with the competition’s theme of “Settlers of the Galaxy“, which challenged teams to find the most energy-efficient way of settling as many star systems as possible.

Of Course Mars 2020 is Going to Get a New Name. NASA is Looking for Judges for an Upcoming Naming Contest

A little over a year from now, NASA’s Mars 2020 rover will launch for Cape Canaveral and begin its journey to the Red Planet. When it arrives, in February 2021, it will begin exploring the Jezero Crater to learn more about Mars’ past and search for evidence of past and present life. But before that happens, this robotic explorer still needs a proper name.

Like its predecessors, Spirit, Opportunity, and Curiosity, the Mars 2020 rover will get its official name with the help of a nationwide contest. Towards this end, NASA recently announced that it has partnered with two organizations to give K-12 students all across the US a chance to name the rover that will continue in the search for life and pave the way for humans to begin exploring Mars.

NASA Model Shows Greenland’s Ice Sheet Will Disappear Over the Next 1000 Years, Raising Sea Levels by 7 Meters

Great news! Humankind’s greatest-ever engineering project is nearing completion. Soon we will have warmed the Earth enough to get rid of all those pesky ice sheets and other frozen areas. The finish line is in sight.

If we all work together for the next thousand years, we’ll finally reach our goal!

Deep Space Atomic Clocks Will Help Spacecraft Answer, with Incredible Precision, if They’re There Yet

The Deep Space Atomic Clock, a new technology from NASA's JPL, may change the way spacecraft navigate in space. Launching in late June aboard the Orbital Test Bed satellite, on the SpaceX's Falcon Heavy rocket, descendants of the technology demonstration could be a key component of a self-driving spacecraft and a GPS-like navigation system at other worlds.Credit: General Atomics Electromagnetic Systems

How do spacecraft know where they are? There’s no GPS out there. Right now, it involves sending a signal to the spacecraft which the spacecraft then sends right back to Earth. The elapsed time reveals the distance.

But on June 24th, that method could be replaced by something much more autonomous.

Enceladus is Filled with Tasty Food for Bacteria

As soon as the Cassini-Huygens mission arrived the Saturn system in 2004, it began to send back a number of startling discoveries. One of the biggest was the discovery of plume activity around the southern polar region of Saturn’s moon Enceladus’, which appears to be the result of geothermal activity and an ocean in the moon’s interior. This naturally gave rise to a debate about whether or not this interior ocean could support life.

Since then, multiple studies have been conducted to get a better idea of just how likely it is that life exists inside Enceladus. The latest comes from the University of Washington’s Department of Earth and Space Sciences (ESS), which shows that concentrations of carbon dioxide, hydrogen and methane in Enceladus’ interior ocean (as well as its pH levels) are more conducive to life than previously thought.

This is the Closest OSIRIS-REx has Gotten to Bennu. Just 680 Meters Above the Asteroid

This image of asteroid Bennu was taken at an altitude of only 690 m (0.4 miles) from the asteroid's surface. It was captured by NavCam 1, one of three cameras in the spacecraft's TAGCAMS (the Touch-and-Go Camera System) suite. Image Credit: NASA/Goddard/University of Arizona/Lockheed Martin

NASA’s OSIRIS-REx spacecraft has been at asteroid Bennu since Dec. 3rd, 2018. On that day, it went from travelling to the asteroid to travelling around it. Since then it’s been surveying and mapping Bennu.
