Look out, Starship! China is Building a Massive Reusable Rocket!

For years, China has been dropping hints about its Long March 9 (CZ-9) rocket, a three-stage super-heavy variant of the Long March family. This launch vehicle will reportedly be capable of transporting up to 150,000 kg (165 tons) to Low Earth Orbit (LEO) and 54,000 kg (59.5 tons) to a trans-lunar injection. On March 2nd, the China Academy of Launch Vehicle Technology (CALT) announced (via the Chinese social media platform Weixin) that it had finished building the first propellant tank for the CZ-9.

The news was accompanied by pictures that showed the finished tank and the many components that went into making it – and they are massive!

It Should be Possible to Farm on the Moon

An astronaut’s gotta eat, right? Especially if they are on a long-duration mission to places like the Moon. Scientists have been looking into how the lunar regolith could possibly support growing food for humans, as growing plants for food and oxygen will be critical for future long-term lunar missions.

One company has been diligently researching this concept and they say there’s good news.

Dust From the Moon Could Help the Shade the Earth and Slow Down Climate Change

Alongside nuclear war or a massive impact from an asteroid, anthropogenic climate change is one of the greatest existential threats facing humanity today. With the rise in greenhouse gas emissions through the 20th century, Earth’s atmosphere continues to absorb more of the Sun’s energy. This has led to rising temperatures, rising sea levels, and increased drought, famine, wildfires, and other ecological consequences. According to the Intergovernmental Panel on Climate Change (IPCC), global temperatures will increase by an average of 1.5 to 2 °C (2.7 to 3.6 °F) by 2050.

For some parts of the world, the temperature increases will be manageable with the right adaptation and mitigation strategies. For others, especially in the equatorial regions (where most of Earth’s population lives), the temperature increases will be severe and will make life untenable for millions of people. For decades, scientists have considered using a sunshield to block a fraction of the Sun’s energy (1 to 2%) before it reaches Earth’s atmosphere. According to a new study by a team led by the University of Utah, lunar dust could be used to shield Earth from sunlight.

A Green Bank Telescope Prototype Radar System Can Image the Moon in High-Resolution and Detect Asteroids

Everyone loves taking pictures of the Moon. Whether it’s with their phones or through the wonders of astrophotography, photographing the Moon reminds us about the wonders and awesomeness of the universe. But while we can take awesome images of the whole Moon from the Earth, it’s extremely difficult to get close-up images of its surface given the enormous distance we are from our nearest celestial neighbor at 384,400 km (238,855 mi). This is because the closer we try to zoom in on its surface, the blurrier, or more pixelated, the images become. Essentially, the resolution of the images becomes worse and worse. But what if we could take high-resolution images of the Moon’s surface from Earth instead of relying on satellites presently in lunar orbit to take them for us?

New Spacecraft Can See Into the Permanently Shadowed Craters on the Moon

Images of the permanently shadowed wall and floor of Shackleton Crater captured by Lunar Reconnaissance Orbiter Camera (LROC) (left) and ShadowCam (right). Each panel shows an area that is 5,906 feet (1,800 meters) wide and 7,218 feet (2,200 meters) tall. Image Credit: NASA/KARI/ASU.

Shackleton Crater at the lunar south pole is one of the locations on NASA’s shortlist for human exploration with the future Artemis missions. But because craters at the lunar poles — like Shackleton — at have areas that are perpetually in shadow, known as permanently shadowed regions (PSRs), we don’t know for sure what lies inside the interior. However, a new spacecraft with a specialized instrument is about to change all that.

South Korea’s Danuri Mission Sends Home Pictures of the Earth and Moon

The Korea Aerospace Research Institute (KARI) both ended 2022 and started 2023 on a very high note as its first-ever lunar orbiter, Danuri, sent back black-and-white images of the Earth with the Moon’s surface in the foreground that were photographed between December 24 and January 1, KARI announced in a January 3^rd statement. Both the images and videos were taken less than 120 kilometers (75 miles) above the Moon’s surface, and will be “used to select potential sites for a Moon landing in 2032,” KARI added in the statement.

NASA has Simulated a Tiny Part of the Moon Here on Earth

Before going to the Moon, the Apollo astronauts trained at various sites on Earth that best approximated the lunar surface, such as the volcanic regions Iceland and Hawaii and deserts in the US Southwest. To help prepare for upcoming robotic and human Artemis missions, a newly upgraded “mini-Moon” lunar testbed will allow astronauts and robots to test out realistic conditions on the Moon including rough terrain and unusual sunlight.

Study Shows How Cells Could Help Artemis Astronauts Exercise

In 2033, NASA and China plan to send the first crewed missions to Mars. These missions will launch every two years when Earth and Mars are at the closest points in their orbits (Mars Opposition). It will take these missions six to nine months to reach the Red Planet using conventional technology. This means that astronauts could spend up to a year and a half in microgravity, followed by months of surface operations in Martian gravity (roughly 40% of Earth gravity). This could have drastic consequences for astronaut health, including muscle atrophy, bone density loss, and psychological effects.

Aboard the International Space Station (ISS), astronauts maintain a strict exercise regimen to mitigate these effects. However, astronauts will not have the same option while in transit to Mars since their vehicles (the Orion spacecraft) have significantly less volume. To address this challenge, Professor Marni Boppart and her colleagues at the Beckman Institute for Advanced Science and Technology are developing a process using regenerative cells. This work could help ensure that astronauts arrive at Mars healthy, hearty, and ready to explore!

Want to Build Structures on the Moon? Just Blast the Regolith With Microwaves

Microwaves are useful for more than just heating up leftovers. They can also make landing pads on other worlds – at least according to research released by a consortium of scientists at the University of Central Florida, Arizona State University, and Cislune, a private company. Their research shows how a combination of sorting the lunar soil and then blasting it with microwaves can create a landing pad for future rockets on the Moon – and save any surrounding buildings from being blasted by 10,000 kph dust particles.

The Solar Wind is Creating Water on the Surface of the Moon

Water on the Moon has been a hot topic in the research world lately. Since its first unambiguous discovery back in 2008. Since then, findings of it have ramped up, with relatively high concentration levels being discovered, especially near the polar regions, particularly in areas constantly shrouded in shadow. Chang’e 5, China’s recent sample return mission, didn’t land in one of those permanently shadowed areas. Still, it did return soil samples that were at a much higher latitude than any that had been previously collected. Now, a new study shows that those soil samples contain water and that the Sun’s solar wind directly impacted that water.
