How will future robotic explorers navigate the difficult subterranean environments of caves and lava tubes on the Moon and Mars? This is what a recent study published in Science Robotics hopes to address as a team of researchers from Stanford University investigated the use of a novel robotic explorer called ReachBot, which could potentially use its unique mechanical design to explore deep caves and lava tubes on the Moon and Mars in the future.

Search for Life on Mars Could Level-Up with MARSE Mission Concept

A recent study presented at the 55^th Lunar and Planetary Science Conference (LPSC) discusses the Mars Astrobiology, Resource, and Science Explorers (MARSE) mission concept and its Simplified High Impact Energy Landing Device (SHIELD), which offers a broader and cheaper method regarding the search for—past or present—life on the Red Planet, specifically by using four rovers at four different landing sites across Mars’ surface instead of just one-for-one. This concept comes as NASA’s Curiosity and Perseverance rovers continue to tirelessly explore the surface of Mars at Gale Crater and Jezero Crater, respectively.

NASA’s VERITAS Mission Breathes New Life

In a win for planetary scientists, and planetary geologists in particular, it was announced at the recent 55^th Lunar and Planetary Science Conference (LPSC) in Texas earlier this month that NASA’s VERITAS mission to the planet Venus has been reinstated into NASA’s Fiscal Year 2025 (FY25) budget with a scheduled launch date of 2031, with the unofficial announcement coming on the first day of the conference, March 11, 2024, and being officially announced just a few days later. This comes after VERITAS experienced a “soft cancellation” in March of last year when NASA revealed its FY24 budget, providing VERITAS only $1.5 million, which was preceded by the launch of VERITAS being delayed a minimum of three years due to findings from an independent review board in November 2022.

NASA and LEGO Continue Brick-Solid Partnership with Perseverance and Ingenuity LEGO Models

Engineers at NASA’s Jet Propulsion Laboratory (NASA-JPL) are busy keeping the Perseverance rover and Ingenuity helicopter functioning in Jezero Crater on Mars while these robotic explorers continue the search for ancient microbial life on the Red Planet. But some of those same engineers have also been busy working with LEGO designers on new one-tenth-scale LEGO Technic buildable models of these very same robotic explorers with the goal of inspiring the next generation of NASA scientists and engineers.

Exploring Lava Tubes on Other Worlds Will Need Rovers That Can Work Together

Planetary exploration, specifically within our own Solar System, has provided a lifetime of scientific knowledge about the many worlds beyond Earth. However, this exploration, thus far, has primarily been limited to orbiters and landers/rovers designed for surface exploration of the celestial bodies they visit. But what if we could explore subsurface environments just as easily as we’ve been able to explore the surface, and could some of these subsurface dwellings not only shelter future astronauts, but host life, as well?

NASA’s Psyche mission is back on track for launch and is now scheduled for a potential October 2023 launch date, according to an October 2022 statement from NASA. This comes after missing its originally planned launch date between August and October of 2022, and becoming subject to an independent review board, whose results were announced in November 2022.

On May 22^nd, 2021, the Zhurong rover – part of Tianwen-1, China’s first mission to Mars – descended from its lander and drove on the Martian surface for the first time. According to the mission’s official social media account, the rover drove down its descent ramp from the Tianwen-1 lander at 10:40 a.m. Beijing time (07:40 p.m. PDT; 10:40 p.m. EDT) and placed its wheels upon the surface of Mars.

Why Lava Tubes Should be Our Top Exploration Priority on Other Worlds

When magma comes out of the Earth onto the surface, it flows as lava. Those lava flows are fascinating to watch, and they leave behind some unique landforms and rocks. But a lot of what’s fascinating about these flows can be hidden underground, as lava tubes.

These lava tubes are turning out to be a very desirable target for exploration on other worlds, just as they are here on Earth.

The Woods Hole Oceanographic Institution (WHOI) says their underwater robot has just completed the first-ever automated underwater sampling operation. The robot is called Nereid Under Ice (NEI) and it collected the sample in Greece. WHOI is developing Nereid in association with NASA’s Planetary Science and Technology from Analog Research (PSTAR) program.

Shape-shifting Robots Like These Could Be Just What We Need to Explore Titan

When it comes to space exploration, it’s robots that do most of the work. That trend will continue as we send missions onto the surfaces of worlds further and further into the Solar System. But for robots to be effective in the challenging environments we need to explore—like Saturn’s moon Titan—we need more capable robots.

A new robot NASA is developing could be the next step in robotic exploration.
