Planetary Surfaces: Why study them? Can they help us find life elsewhere?

Universe Today recently explored the importance of studying impact craters and what they can teach us about finding life beyond Earth. Impact craters are considered one of the many surface processes—others include volcanism, weathering, erosion, and plate tectonics—that shape surfaces on numerous planetary bodies, with all of them simultaneously occurring on Earth. Here, we will explore how and why planetary scientists study planetary surfaces, the challenges faced when studying other planetary surfaces, what planetary surfaces can teach us about finding life, and how upcoming students can pursue studying planetary surfaces, as well. So, why is it so important to study planetary surfaces throughout the solar system?

We've Entered a New Era: The Lunar Anthropocene

For almost half a century, the term “Anthropocene” has been informally used to describe the current geological epoch. The term acknowledges how human agency has become the most significant factor when it comes to changes in Earth’s geology, landscape, ecosystems, and climate. According to a new study by a team of geologists and anthropologists, this same term should be extended to the Moon in recognition of humanity’s exploration (starting in the mid-20th century) and the growing impact our activities will have on the Moon’s geology and the landscape in the near future.

The History of the Sun is Written on the Moon

If you want to learn about the history of the Sun, then look no further than the Moon. That’s the recommendation of a team of scientists who hope to harness future Artemis lunar missions to help understand the life history of our home star.

2024 Artemis Landings Could Slip Because of a Lack of Spacesuits. Musk Offers to Develop Them

In March of 2019, NASA was directed to develop all the necessary equipment and planning to send astronauts back to the Moon by 2024. This plan, officially named Project Artemis, was part of an agency-wide shakeup designed to ensure that the long-awaited return to the Moon takes place sooner than NASA had originally planned. In accordance with their “Moon to Mars” framework, NASA hoped to assemble the Lunar Gateway first, then land astronauts on the surface by 2028.

Unfortunately, this ambitious proposal has led to all sorts of complications and forced NASA to shift certain priorities. Most recently, NASA’s Office of Inspector General (OIG) submitted a report that indicated that their new Exploration Extravehicular Mobility Units (xEMU) spacesuits will not be ready in time. The resulting delay has prompted Elon Musk to offer the services of SpaceX to expedite the spacesuit’s development and get Artemis back on schedule.

Earth’s Oxygen Could be Making the Moon Rust

It takes oxygen to make iron rust. So when scientists discovered hematite spread widely through lunar high latitudes, they were surprised. How did that happen?

A new study suggests that oxygen from Earth could be playing a role in rusting the Moon.

The Moon is an Ideal Spot for a Gravitational Wave Observatory

In the coming years, multiple space agencies will be sending missions (including astronauts) to the Moon’s southern polar region to conduct vital research. In addition to scouting resources in the area (in preparation for the construction of a lunar base) these missions will also investigate the possibility of conducting various scientific investigations on the far side of the Moon.

However, two prominent scientists (Dr. Karan Jani and Prof. Abraham Loeb) recently published a paper where they argue that another kind of astronomy could be conducted on the far side of the Moon – Gravitational Wave astronomy! As part of NASA’s Project Artemis, they explain how a Gravitational-wave Lunar Observatory for Cosmology (GLOC) would be ideal for exploring GW in the richest and most challenging frequencies.
