The Surface of Mars Might Have Gotten an Acid Bath, Obscuring Evidence of Past Life

People have been speculating about the possibility of life on Mars for centuries. But it’s only since the 1970s and the Viking 1 and 2 missions that we have been able to search for it. After many decades, evidence has mounted that Mars may have once supported life (like the existence of flowing water and organic molecules), but evidence of present-day life has remained elusive.

Unfortunately, according to a recent study by an international team of scientists led by the Spanish Astrobiology Center (CSIC-INTA), it’s possible that the surface of Mars was bathed in acid and alkaline fluids that destroyed all evidence of past life. These findings could have serious implications for upcoming missions to Mars, which includes NASA’s Perseverance and the ESA’s Rosalind Franklin rover.

It Looks Like Firefighters Saved Mt. Wilson Observatory

Every year, the Pacific Northwest and California experience “wildfire season,” a period where heat and low humidity combine, leading to an increased risk of fires. This year has been particularly bad and in California alone, wildfires have destroyed over two million acres of land, forced hundreds of thousands of people from their homes, and threatened many historic institutions and landmarks.

One of them is the Mount Wilson Observatory that sits atop Mount Wilson in the San Gabriel Mountains overlooking Pasadena (northeast of LA). This famous observatory is home to several telescopes that were, for a time, the largest of their kind in the world. And thanks to the heroic efforts of firefighters, it looks as though the Mt. Wilson Observatory is now safe amid a particularly bad wildfire season.

During the Apollo Era, astronauts conducted vital science operations on the Moon, which included bringing samples of lunar rocks back to Earth for study. Thanks to the examination of these rocks, scientists were able to learn a great deal about the formation and evolution of the Moon and even found evidence of lunar water. In the coming years, when NASA sends astronauts back as part of Project Artemis, more samples will be returned.

Recently, NASA put out the call for science white papers to help them design a framework for the kind of science operations the Artemis astronauts will conduct. According to one proposal, the Artemis astronauts should not only bring back samples of lunar regolith or rocks but lunar ice as well. By examining them here on Earth, scientists may finally be able to resolve the mystery of where the Moon’s water came from.

With the closing of the Apollo Era, the priorities of the world’s space agencies began to shift. Having spent the past two decades racing to send astronauts to orbit and to the Moon, the focus now changed towards developing the technologies needed to stay there. A new era of international cooperation, space stations, and partnerships between space agencies and the commercial industry is what followed.

In the near future, things are expected to become even more interesting, with plans for the commercialization of Low Earth Orbit (LEO), the mining of Near-Earth Asteroids (NEAs), and the establishment of a permanent human presence on the Moon. Beyond the logistical and technical challenges this poses, there’s been no shortage of concern about the legal issues and implications this will raise as well.

To this end, a group of legal scholars and space experts recently came together to form the Space Court Foundation (SCF), a non-profit educational organization created to foster a conversation about these and other related space issues. By beginning the conversation now, they hope, the public will be able to play an active role in the burgeoning and evolving domain known as “space law.”

As part of Project Artemis, NASA intends to send the first woman and the next man to the Moon by 2024, in what will be the first crewed mission to the lunar since the Apollo Era. By the end of the decade, NASA also hopes to have all the infrastructure in place to create a program for “sustainable lunar exploration,” which will include the Lunar Gateway (a habitat in orbit) and the Artemis Base Camp (a habitat on the surface).

Part of this commitment entails the recovery and use of resources that are harvested locally, including regolith to create building materials and ice to create everything from drinking water to rocket fuel. To this end, NASA has asked its commercial partners to collect samples of lunar soil or rocks as part of a proof-of-concept demonstration of how they will scout and harvest natural resources and conduct commercial operations on the Moon.

The SpaceX Starship Could be Making its Biggest Hop Yet (and a Belly-Flop) Next Month!

SpaceX is getting closer to the day when it will be able to make good on its promise of conducting regular missions to orbit, the Moon, and to Mars. At the heart of all this is the progress they are making with their Starship and Super Heavy launch system. In recent weeks, Musk’s commercial space company conducted two successful 150 m (500 ft) hop tests with the SN5 and SN6 prototypes at the Boca Chica launch facility in southern Texas.

Based on the latest announcements to come out of SpaceX, it appears that this recent string of successes has emboldened Musk and his company. Previously, Musk indicated that he was planning on making several more small hop tests and that the SN8 would attempt a 20 km (12 mi) flight sometime next year. More recent indications, however, suggest that Musk wants to conduct this high-altitude test before the end of October.

An Update on the Damage to the Arecibo Observatory

On Aug. 10th, a little over a month ago, the iconic Arecibo Observatory suffered serious damage when an auxiliary cable broke and struck the reflector dish. This cable struck the observatory’s Gregorian Dome on its way down and twisted an access platform before landing on the reflecting dish itself. The impact created a gash over 30 meters (100 feet) in length and forced the observatory to shut down until repairs could be made.

Since then, teams have been busy working to stabilize the structure and determine the cause. These teams are made up of technicians from the observatory and the University of Central Florida (UCF), which manages the facility for the National Science Foundation (NSF). For the past few weeks, they have been meeting with experts from various fields and laying the groundwork for an investigation and a rigorous repair schedule.

China’s New Reusable Spaceplane Lands After 2 Days in Space

On Friday, Sept. 4th, China launched a new and mysterious spacecraft from the Jiuquan Satellite Launch Center. The nature (and even appearance) of the spacecraft remains unknown, but according to statements made by Chinese authorities, it’s a reusable spaceplane. This vehicle is essentially China’s answer to the USAF/USSF X-37B Orbital Test Vehicle (OTV), which made its sixth launch to space (OTV-6) back in late-May.

Welcome back to our Fermi Paradox series, where we take a look at possible resolutions to Enrico Fermi’s famous question, “Where Is Everybody?” Today, we examine the possibility that we haven’t heard from aliens because intelligent life only survives for so long.

In 1950, Italian-American physicist Enrico Fermi sat down to lunch with some of his colleagues at the Los Alamos National Laboratory, where he had worked five years prior as part of the Manhattan Project. According to various accounts, the conversation turned to aliens and the recent spate of UFOs. Into this, Fermi issued a statement that would go down in the annals of history: “Where is everybody?“

This became the basis of the Fermi Paradox, which refers to the disparity between high probability estimates for the existence of extraterrestrial intelligence (ETI) and the apparent lack of evidence. Since Fermi’s time, there have been several proposed resolutions to his question, which include the possibility that civilizations only have a “Brief Window” with which to communicate with the cosmos before going extinct.

In the near future, launch facilities located at sea are expected to be a lot more common. SpaceX announced that it is hoping to create offshore facilities in the near future for the sake of launching the Starship away from populated areas. And China, the latest member of the superpowers-in-space club, is currently building the “Eastern Aerospace Port” off the coast of Haiyang city in the eastern province of Shandong.

This mobile launch facility is being developed by the China Aerospace Science and Technology Corporation (CASC), the country’s largest aerospace and defense contractor. Once fully operational, it will be used to launch light vehicles, as well as for building and maintaining rockets, satellites, and related space applications. As China’s fifth launch facility, it will give the country’s space program a new degree of flexibility.
