Underground habitats have recently become a focal point of off-planet colonization efforts. Protection from micrometeorites, radiation, and other potential hazards makes underground sites desirable compared to surface dwellings. Building such subterranean structures presents a plethora of challenges, not the least of which is how to actually construct them. A team of researchers at the Delft University of Technology (TUD) is working on a plan to excavate material and then use it to print habitats. All that would be done with a group of swarming robots.Continue reading “Swarms of Robots Could Dig Underground Cities on Mars”
On Feb. 18th, 2021, the Perseverance rover landed on Mars carrying the most advanced scientific instruments ever sent to another planet. It also carried experiments designed to push the envelope of exploration and help pave the way for crewed missions to Mars. This includes the Ingenuity Mars Helicopter, an experimental flight system designed to see if aerial systems can operate in the Martian atmosphere.
After making its inaugural flight on April 19th, Ingenuity has taken to the air twice more and set many records in the process. During its most recent test flight (which took place on the morning of April 25th), the helicopter flew farther and faster than ever before. All told, the helicopter covered a distance of 50 meters (164 feet) in 80 seconds, reaching a top speed of 2 m/s (6.6 feet per second) or 7.2 km/hour (4.5 mph).Continue reading “Ingenuity Completes a Huge 50-Meter Flight on Mars”
Mars’ surface is a harsh environment for life. But life on Earth is notoriously resilient as well. No one is quite sure yet how microbes from Earth would fare on the Martian surface. However, the impact of a potential transmigration of microbes to the red planet could be immense. Not only could it skew any findings of potential real Martian life we might find, it could also completely disrupt any nascent biosphere that Mars might have.
To understand whether that much disruption is really possible, first we must understand whether any Earthly life can survive on Mars itself. According to a new study recently published in Frontiers in Microbiology, the answer to that is yes.Continue reading “Some Earth Life Could Already Survive on Mars”
It’s looking more and more like the future of space exploration could involve drones in a big way.
We’ve already seen it here on Earth, where all kinds of flying drones are used by all kinds of people for all kinds of things. Drones are particularly useful in resource development, exploration, imaging, and remote sensing.
Could the future see drones flying around in the thin Martian atmosphere?Continue reading “New Drones for Exploring Mars are Getting Tested in Iceland”
Growing meat without the need to grow a whole animal has been the dream of agriculturalists and foodies everywhere for decades. More and more companies are jumping on the bandwagon to try to truly recreate the experience of eating meat without the downsides so often associated with its creation. One of those companies is Aleph Farms, based in Israel, which just announced their newest program – Aleph Zero, an effort to grow meat in industrial quantities in space.Continue reading “Astronauts and explorers on Mars could eat lab-grown steaks”
Get used to hearing the name “Jezero Crater.” It’s the landing site for NASA’s Mars 2020 rover. The 2020 rover is slated to launch in July 2020, and will land at Jezero Crater in February, 2021.
It’s pretty easy to see why NASA chose Jezero Crater for the next rover in their Mars Exploration Program (MEP). MEP is NASA’s long-term plan to explore Mars robotically. It includes rovers like Spirit, Opportunity, and MSL, the InSight Lander, orbiting spacecraft, and soon the 2020 rover.Continue reading “This is Where Mars 2020 Rover is Heading. From this Picture, I Think You Can Guess Why”
Welcome to the moons of Mars, as you’ve never seen them.
NASA’s aging 2001 Mars Odyssey orbiter recently snapped some unique views of the twin moons Phobos and Deimos, in an effort to better understand their texture and surface composition. The images are courtesy of the spacecraft’s THEMIS (the Thermal Emission Imaging System) heat sensitive instrument, and show the thermal gradient across the surface of the moons in color. Odyssey has been studying the moons of Mars since September 2017. The recent images of Phobos taken on April 24, 2019 are especially intriguing, as they occurred during full illumination phase.Continue reading “Mars Odyssey Reveals Phobos Using THEMIS”
We’ve known for some time that NASA is sending a helicopter to Mars. The vehicle, called the Mars Helicopter, is undergoing flight testing at NASA’s Jet Propulsion Laboratory in California. The little helicopter will make its eventual way to Mars as part of the Mars 2020 Rover mission.
The Mars Helicopter is pretty small, less than 1.8 kg (4 lb). It’s made of lightweight carbon fiber, and other materials like aluminum, silicon, and foil. The version being tested is the actual vehicle that will make the trip to Mars.Continue reading “Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars”
Some new images sent home by the InSight Lander show the robotic arm and the craft’s instruments waiting on deck, on the surface of Mars. The lander is still having its systems tested, and isn’t quite ready to get to work. It’ll use its arm to deploy its science instruments, including a drill that will penetrate up to 5 meters (16 ft.) deep into the Martian surface.
There’s solid evidence for the existence of water on Mars, at least in frozen form at the planet’s poles. And a more recent study confirms the existence of liquid water at the south pole. But visitors to Mars will need to know the exact location of usable water deposits at other Martian locations. A ground-penetrating radar called ScanMars may be up to the task.
