In accordance with Space Policy Directive-1 – which was issued on December 11th, 2017 – NASA is busy developing all the necessary hardware to return astronauts to the Moon. On March 26th, 2019, NASA was officially directed to expedite the process and land the first astronauts of the post-Apollo era around the lunar South Pole by 2024. This mission is named Project Artemis, who is the twin sister of Apollo in Greek mythology.
Over the weekend, Vice President Mike Pence visited the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida to commemorate the 50th anniversary of the Apollo 11 Moon Landing. The occasion also saw the unveiling of the Orion crew capsule that will be used for the first Artemis lunar mission. The event, therefore, served as both a retrospective and a look at the future of lunar exploration.

On March 26th, 2019, during the fifth meeting of the reestablished National Space Council, Vice President Mike Pence challenged NASA to land astronauts on the Moon within the next five years. This represented an order to expedite Space Policy Directive-1 signed by President Trump on December 11th, 2017, which directed NASA to take all the necessary steps to send astronauts back to the Moon.
This announcement suggested that some shake-up might be taking place within the agency to make things happen. However, it appears that this now involves the demotion of two longtime NASA heads who have dedicated much of their lives to the advancement of human space exploration. Whether or not this decision came from the White House is unclear, but it is in keeping with the direction recently issued by VP Pence.

When it comes to the future of space exploration, a number of systems will come into play. In addition to the Space Launch System (SLS) that will send astronauts beyond Low Earth Orbit (LEO), there is also the Orion capsule. This is the vehicle that will take astronauts to the Moon again as part of Project Artemis (which is currently slated for 2024) and facilitate missions to Mars by the 2030s.
In preparation, the Orion capsule is being put through its paces to show that it’s up to the challenge. This past Tuesday, July 2nd, NASA successfully conducted the Ascent Abort-2 (AA-2) test, bringing the Orion one step closer to completion. The launch took place during the early morning hours and involved the capsule being launched from NASA’s Space Launch Complex 46 at Cape Canaveral aboard a modified Peacekeeper missile.

The Moon is not just Earth’s closest celestial neighbor. It’s also a natural waypoint for any mission that will be going to Mars or beyond in the coming years. It’s little wonder then why space agencies like NASA, Roscosmos, the ESA and China are hoping to send crewed missions there in the near future and construct bases that could be used to resupply and refuel missions headed to deep space.
So far, all the proposals made for a lunar base have centered on in-situ resource utilization (ISRU) and 3D printing – where robots will manufacture the base out of lunar regolith. For this purpose, the Laser Zentrum Hannover (LZH) and the Institute of Space Systems (IRAS) at the Technical University of Braunschweig came together to develop a laser system capable of turning moon dust into building materials.

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.
