On January 3rd, 2019, the Chinese National Space Administration (CNSA) successfully landed their Chang’e-4 mission on the far side of the Moon. This mission represents a major milestone for China, being the fourth lander-rover mission to be sent to the Moon, and the first mission in history to land on the “dark side of the Moon”. And what it manages to uncover there is sure to excite and inspire scientists for many years to come.
For example, the mission’s Yutu-2 (Jade Rabbit-2) rover made an impressive find that may confirm a theory about lunar impacts. After collecting spectral data from the moon’s largest crater (the South Pole-Aitken Basin) the Chang’e-4 mission team from the Chinese Academy of Sciences (CAS) concluded that the impact that created the Basin turned up material from deep within the Moon’s mantle. This finding could offer new insight into how the Moon evolved over the course of billions of years.

There is no doubt that our world is in the midst of a climate crisis. Between increasing levels of carbon dioxide in our atmosphere, rising temperatures and sea levels, ocean acidification, species extinctions, waste production, diminishing supplies of fresh water, drought, severe weather, and all of the resulting fallout, the “Anthropocene” is not shaping up too well.
It is little wonder then why luminaries like Stephen Hawking, Buzz Aldrin, and Elon Musk believe that we must look off-world to ensure our survival. However, there are those who caution that in so doing, humans will simply shift our burdens onto new locations. Addressing this possibility, two distinguished researchers recently published a paper where they suggest that we should set aside “wilderness” spaces” in our Solar System today.

Since the late 19th century, scientists have struggled to explain the origin of the Moon. While scientists have long-theorized that it and the Earth have a common origin, the questions of how and when has proven to be elusive. For instance, the general consensus today is that an impact with a Mars-sized object (Theia) led to the formation of the Earth-Moon System shortly after the formation of the planets (aka. the Giant Impact Hypothesis).
However, simulations of this impact have shown that the Moon would have formed out of material primarily from the impacting object. This is not borne out by the evidence, though, which shows that the Moon is composed of the same material Earth is. Luckily, a new study by a team of scientists from Japan and the US has offered an explanation for the discrepancy: the collision took place when Earth was still composed of hot magma.

July 20st, 2019, will mark the 50th anniversary of the historic Moon Landing, where astronauts Neil Armstrong and Buzz Aldrin set foot on the lunar surface for the first time. This accomplishment was the high point of the “Space Race” and has remained NASA’s crowning achievement in space. In the coming years, NASA will attempt to return to the Moon, where they will be joined by several other space agencies.
To prepare for these eventual missions, a group of cosmonauts recently commenced an isolation experiment that will simulate a long-term mission to the Moon. It’s called the SIRIUS-19 experiment, which began earlier today at 02:00 p.m. local time (04:00 a.m. PDT; 07:00 a.m. EDT) at the Russian Academy of Sciences’ Institute of Biomedical Problems (IBMP) in Moscow.

Ever since the Apollo missions explored the lunar surface, scientists have known that the Moon’s craters are the result of a long history of meteor and asteroid impacts. But it has only been in the past few decades that we have come to understand how regular these are. In fact, every few hours, an impact on the lunar surface is indicated by a bright flash. These impact flashes are designed as a “transient lunar phenomena” because they are fleeting.
Basically, this means that the flashes (while common) last for only a fraction of a second, making them very difficult to detect. For this reason, the European Space Agency (ESA) created the NEO Lunar Impacts and Optical TrAnsients (NELIOTA) project in 2015 to monitor the moon for signs of impact flashes. By studying them, the project hopes to learn more about the size and distribution of near-Earth objects to determine if they pose a risk to Earth.

Hello all. I hope our readers don’t mind that I’m taking a bit of a diversion here today to engage in a little shameless self-promotion. Basically, I wanted to talk about my recently-published novel – The Jovian Manifesto. This book is the sequel to The Cronian Incident, which was published last year (and was a little shamelessly promoted at the time).
However, I also wanted to take this opportunity to talk about hard science fiction and how writing for a science publication helped me grow as a writer. By definition, hard sci-fi refers to stories where scientific accuracy is emphasized. This essentially means that the technology in the story conforms to established science and/or what is believed to be feasible in the future.

Time capsules are a fun and time-honored way to preserve pieces of the past. In most cases, they include photographs, mementos and other items of personal value, things that give future generations a sense of what life was like in the past. But what if we intend to preserve the memories and experiences of an entire species for thousands of years? What would we choose to squirrel away then, and where would be place it?
That’s precisely what researchers from the Molecular Information Systems Lab at the University of Washington (UW) and Microsoft had in mind when they announced their #MemoriesInDNA project. This project invites people to submit photos that will be encoded in DNA and stored for millennia. And thanks to a new partnership with the Arch Mission Foundation, this capsule will be sent to the Moon in 2020!

In the coming decades, NASA has ambitious plans to send astronauts back to the Moon and conduct the first crewed mission to Mars. In order to accomplish these lofty goals, the agency is investing in cutting-edge technology and partnering with major aerospace companies to create the necessary spacecraft and mission components.
One such component, which will allow astronauts to travel to and from the lunar surface, is Lockheed Martin’s concept for a reusable lunar lander. The concept was presented today at the 69th annual International Astronautical Congress (IAC) in Bremen, Germany, where space agency and industry experts were treated to the latest in space exploration advancements.

In the coming decades, NASA intends to mount some bold missions to space. In addition to some key operations to Low Earth Orbit (LEO), NASA intends to conduct the first crewed missions beyond Earth in over 40 years. These include sending astronauts back to the Moon and eventually mounting a crewed mission to Mars.
To this end, NASA recently submitted a plan to Congress that calls for human and robotic exploration missions to expand the frontiers of humanity’s knowledge of Earth, the Moon, Mars, and the Solar System. Known as the National Space Exploration Campaign, this roadmap outlines a sustainable plan for the future of space exploration.

In 2003, the European Space Agency (ESA) launched the Small Missions for Advanced Research in Technology-1 (SMART-1) lunar orbiter. After taking 13 months to reach the Moon using a Solar Electric Propulsion (SEP) system, the orbiter then spent the next three years studying the lunar surface. Then, on September 3rd, 2006, the mission came to an end as the spacecraft was deliberately crashed onto the lunar surface.
While the bright flash that this created was captured by observers using the Canada-France-Hawaii Telescope in Hawaii, no other spacecraft were in orbit at the time to witness it. As a result, it has been impossible for over a decade to determine precisely where SMART-1 went down. But thanks to images captured last year by NASA’s Lunar Reconnaissance Orbiter (LRO), the final resting place of SMART-1 is now known.
