NASA May Have Found Hakuto-R’s Crash Site

This animated image shows the before and after comparison of the possible Hakuto-R impact site. Arrow A points to a prominent surface change with higher reflectance in the upper left and lower reflectance in the lower right (opposite of nearby surface rocks along the right side of the frame). Arrows B-D point to other changes around the impact site [NASA/GSFC/Arizona State University].

New images from NASA’s Lunar Reconnaissance Orbiter (LRO) appear to show the crash site where the Japanese Hakuto-R Mission 1 lunar lander impacted the surface of the Moon a month ago.

The refrigerator-sized HAKUTO-R was built by the startup company iSpace and was launched in December 2022 with the goal of becoming the first commercial lunar lander to touch down safely on the Moon. However, during landing operations on April 25, 2023, communications ceased just moments before touchdown should have occurred, and the lander was presumed lost.

The Moon has a Solid Core Like the Earth

Some fifty years ago, the Apollo Program sent the first astronauts to the Moon. In addition to the many science experiments they conducted on the surface, the Apollo astronauts brought back samples of lunar rock for analysis. The Soviet Luna program sent several robotic missions to the Moon around the same time that conducted sample-return missions. The examination of these rocks revealed a great deal about the composition of the Moon and led to new theories about the formation and evolution of the Earth-Moon system.

For example, analysis of the rocks revealed that the Earth and the Moon are similarly composed of silicate minerals and metals. This led to theories that the Moon’s interior is similarly divided into a silicate mantle and crust and a metallic core. However, many aspects of this theory, like the structure of the core (solid or molten?), have been debated for decades. According to new findings by a team of French scientists, it is now a scientific certainty that the Moon’s innermost region consists of a solid inner core surrounded by a molten outer core (just like Earth’s).

NASA Shuts Down the Lunar Flashlight Mission After it Fails to Go into Orbit

NASA missions can be categorized into two types. One type includes headline-grabbing missions, such as the JWST or New Horizons, that take decades to design and plan. Typically those larger missions include many flight-tested components that had already been used on other missions in the past. They are intended to conduct science experiments. But those components get tested beforehand on what the agency calls “technology demonstration” flights. These are intended to work through the kinks in technology development that might hinder the use of a system in space. Lunar Flashlight was one of those technology demonstrator missions, but unfortunately, one of the critical novel components did run into one of those kinks, and now NASA has decided to shut down the mission.

Glass Fibers in Lunar Regolith Could Help Build Structures on the Moon

Through the Artemis Program, NASA plans to send the first astronauts to the Moon in over fifty years. Before the decade is over, this program aims to establish the infrastructure that will allow for a “sustained program of lunar exploration and development.” The European Space Agency (ESA) also has big plans, which include the creation of a Moon Village that will serve as a spiritual successor to the International Space Station (ISS). China and Roscosmos also came together in June 2021 to announce that they would build the International Lunar Research Station (ILRS) around the lunar south pole.

In all cases, space agencies plan to harvest local resources to meet their construction and long-term needs – a process known as In-Situ Resource Utilization (ISRU). Based on samples returned by the fifth mission of the Chinese Lunar Exploration Program (Chang’e-5), a team of researchers from the Chinese Academy of Sciences (CAS) identified indigenous glass fibers for the first time. According to a paper they authored, these fibers were formed by past impacts in the region and could be an ideal building material for future lunar bases.

Is This Nearby Asteroid a Chunk of the Moon?

The Moon dominates our view of the night sky. But it’s not the only thing orbiting Earth. A small number of what scientists call quasi-satellites also orbit Earth.

One of them is called Kamo’oalewa, and it’s a near-Earth asteroid. It’s similar to the Moon in some respects. Could it be a chunk of the Moon?

We Can Now See Into the Permanently Shadowed Craters on the Moon

An instrument called ShadowCam is giving NASA’s planned Artemis missions to the Moon some advanced views of a landing site. It’s mounted to the Danuri Korea Pathfinder Lunar orbiter sent to the Moon last year. Lately, this amazing camera has been sending back some highly detailed images of the lunar north and south pole regions.

One Day Astronauts Will Be Breathing Oxygen Made From Rocks

When there’s a permanent base on the Moon, astronauts will need a way to replenish their oxygen supply. Fortunately, there’s an almost infinite amount of oxygen in the surrounding regolith, locked up the rocks and soil. The key would be to figure out a cost-effective way to extract it.

Now, NASA has demonstrated that they can harvest oxygen from the lunar regolith, even in the vacuum conditions of space. They used a device called a carbothermal reactor to successfully extract oxygen from a simulated lunar regolith, while also simulating the heat that would be produced by a solar energy concentrator.

NASA Seeks Greater Diversity in Research Collaborations

In its pursuit of scientific research and human spaceflight, NASA engages in partnerships with various universities, laboratories, and academic institutes. In keeping with NASA’s policy of Diversity, Equity, Inclusion, and Accessibility and the Science Mission Directorate’s (SMD) Science Plan, NASA is seeking to expand its partnerships and encourage “a culture of diversity, inclusion, equity, and accessibility.” To this end, NASA created the Minority University Research and Education Project Partnership (MUREP) – administered through its Office of STEM Engagement (OSTEM).

Through MUREP, NASA provides expert guidance and financial assistance via competitive awards to Minority Serving Institutions (MSIs), which are announced annually through a MUREP Partnership Learning Annual Notification (MPLAN). NASA has teamed up with the leading crowdsourcing platform HeroX for this year’s MUREP opportunity and is awarding multiple prizes of $50,000 to MSIs for innovative ideas and action plans for commercialization that will advance NASA’s Mission Directorate priorities.

Japanese Company’s Moon Lander Is Presumed Lost After Going Silent

A lunar lander built and operated by ispace, a Japanese startup, descended to the surface of the moon today after a months-long journey — but went out of contact and was presumed lost.

“We have to assume that we could not complete the landing on the lunar surface,” ispace CEO Takeshi Hakamada said during a webcast of the Hakuto-R mission’s final stages.

Ground controllers at the Hakuto-R Mission Control Center in Tokyo continued trying to re-establish communications nevertheless, and Hakamada said his company would try again.

“We are very proud of the fact that we have achieved many things during this Mission 1,” he said. “We will keep going. Never quit the lunar quest.”

Hakuto-R Spacecraft Just Captured its Own Stunning Version of ‘Earthrise’

The Hakuto-R lunar lander, currently in orbit around the Moon, just captured a beautiful “Earthrise”-like image, and one with an interesting side note. The Mission 1 lander, from the Tokyo-based commercial company ispace, took the image during the time of the April 20 solar eclipse, where totality was visible in Australia; and so the photo includes a perfect view of the shadow of the Moon passing above the Land Down Under.

The spacecraft was approximately 100 km (60 miles) above the lunar surface when it took the photo.
