BepiColumbo Makes its Third Flyby of Mercury, Seeing the Planet's Night Side

ESA’s BepiColumbo continues its journey to Mercury by making another flyby … of Mercury! This is the third of six planned flybys of its destination planet, each of which gives the spacecraft a gravitational deceleration. Eventually, it’ll slow down enough to go into its final operational orbit.

In the most recent flyby on June 19, 2023, the spacecraft sped past the planet’s night side and took a series of images from 236 km (145 miles) above Mercury’s surface. From these 217 images, the BepiColumbo team created a movie of the flyby, which includes a 3D scene.

If We Can Master Artificial Photosynthesis, We Can Thrive in Space

By 2030, multiple space agencies will have sent astronauts to the Moon for the first time since the Apollo Program ended over 50 years ago. These programs will create lasting infrastructure, like the Lunar Gateway, Artemis Base Camp, Moon Village, and the International Lunar Research Station (ILRS). In the ensuing decade, the first crewed missions to Mars are expected to occur, culminating with the creation of the first human outposts on another planet. Commercial ventures also want to establish habitats in Low Earth Orbit (LEO), enabling everything from asteroid mining to space tourism.

One of the biggest challenges for this renewed era of space exploration (Space Age 2.0) is ensuring that humans can remain healthy while spending extended periods in space. Foremost among them is ensuring that crews have functioning life support systems that can provide a steady supply of breathable air, which poses its own technical challenges. In a recent study, a team of researchers led by Katharina Brinkert of the University of Warwick described how artificial photosynthesis could lead to a new type of life support system that is smaller, lighter, easier, and more cost-effective to send to space.

ESA Has a Playground for Mars Rovers to Learn how to Explore the Red Planet

NASA makes successful rover missions seem mundane. Spirit and Opportunity were wildly successful, and Curiosity and Perseverance would both be considered successes even if they stopped working today. But complex missions don’t succeed without rigorous testing.

The ESA takes that lesson to heart, and when it comes to their Mars rover, they’ve built a ‘rover playground’ to test it in.

Researchers Are Building a Simulated Moon/Mars Research Station Deep Underground

In the early days of spaceflight, just getting a satellite into Earth’s orbit was an accomplishment. In our era, landing rovers on other planets and bringing samples home from asteroids is the cutting edge. But the next frontier is rapidly approaching, when astronauts will stay for long periods of time on the Moon and hopefully Mars.

But before we can send people to those dangerous environments, the Artemis partner space agencies have to know how to keep them safe. An important part of that is simulating the conditions on the Moon and Mars.

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.

Could We Resurrect the Spitzer Space Telescope?

NASA’s Spitzer Space Telescope served the astronomy community well for 16 years. From its launch in 2003 to the end of its operations in January 2020, its infrared observations fuelled scientific discoveries too numerous to list.

Infrared telescopes need to be kept cool to operate, and eventually, it ran out of coolant. But that wasn’t the end of the mission; it kept operating in ‘warm’ mode, where observations were limited. Its mission only ended when it drifted too far away from Earth to communicate effectively.

Now the US Space Force thinks they can reboot the telescope.

New Photos Show Collapsed Chains of Craters on a Martian Volcano

Most everyone is familiar with Olympus Mons, the largest volcano on Mars and also the largest in the Solar System. But there are several other enormous shield volcanoes on Mars. The second largest is Ascraeus Mons, and new images from ESA’s Mars Express spacecraft reveal some interesting features on the side or flank of the mountain.

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.

New High-Resolution Photos of Deimos From the Hope Mission

We’ve seen our share of photos of Mars from orbit and the surface, but what about its moons? The United Arab Emirates Hope orbital mission to Mars sent home new beautiful high-resolution images of the Red Planet’s moon Deimos when it flew within 100 km of the moon last month. This is the closest any spacecraft has been to Deimos in almost 50 years.

In the photos, the science team says that their images of Deimos help provide evidence that the moon wasn’t a captured asteroid but came from Mars itself during an impact in the ancient past, much like Earth’s Moon.

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.
