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.

More than a hundred years after geologists first observed how seismic waves traveled through Earth, they’ve achieved another seismic first. This time, they measured “core-transiting seismic waves” moving through Mars. The InSight lander’s seismic instrument tracked shockwaves generated by an earthquake and an impact event. Their behavior revealed for the first time that Mars very likely has a liquid core. It’s made of a single blob of molten iron alloy.

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.

We Can Only Bring 30 Samples of Mars Back to Earth. How Do We Decide?

The Mars Sample Return Mission is one of the most ambitious missions ever conceived. Though the samples won’t be returned to Earth until 2033 at the earliest, the Perseverance Rover is busy collecting them right now. Ideally, Perseverance could gather as many samples as we like and ship them all back to Earth. But of course, that’s not possible.

There are limitations, and this means that choosing which samples to return to Earth is an extremely critical task.

China's Mars Rover Finds Recent Evidence of Water Near the Equator

The surface of Mars is a pretty desolate place at first glance. The soil is many times as dry as the driest desert on planet Earth, the temperatures swing from one extreme to the other, and the air is incredibly thin and toxic. And yet, there’s ample evidence that the planet was once much warmer and wetter, with lots of flowing and standing water on its surface. Over time, as Mars’ atmosphere was slowly stripped away, much of this water was lost to space, and what remains is largely concentrated around the poles as glacial ice and permafrost.

For years, space agencies have been sending robotic landers, rovers, orbiters, and aerial vehicles to Mars to learn more about when this transition took and how long it took. According to China’s Tianwen-1 mission, which includes the Zhurong rover, there may have been liquid water on the Martian surface later than previously thought. According to new research from the Chinese Academy of Sciences (CAS), the Zhurong rover observed salt-rich dunes in the Utopia Planitia region that showed cracks and crusts, indicating the possible presence of water as recently as a few hundred thousand years ago.

It’s Surprisingly Easy to Hurl Rocks From Mars Into Space

Of the thousands of meteorites found on Earth, about 188 have been confirmed to be from Mars. How did they get here? Over the tumultuous history of our Solar System, asteroids have smashed into Mars with such force, the debris was blasted off the planet and then drifted through space, eventually entering Earth’s atmosphere, and surviving the journey to the ground.

Astronomers once thought it was a complex process, with only the most powerful impacts capable of throwing rocks from Mars into space. But new research shows that it takes much less pressure than previously believed, which means there could be more chunks of Mars floating in space and on their way to Earth.

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.

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.

NASA is Sending Humans Back to the Moon, But it Won't Stop There. Next Comes Mars

Credits: NASA

NASA recently announced the astronauts that will make up the Artemis II crew. This mission will see the four-person crew conduct a circumlunar flight, similar to what the uncrewed Artemis I mission performed, and return to Earth. This mission will pave the way for the long-awaited return to the Moon in 2025, where four astronauts will fly to the Moon, and two (“the first woman and first person of color“) will land on the surface using the Starship HLS. These missions are part of NASA’s plan to establish a program of “sustained lunar exploration and development.”

As NASA has emphasized for over a decade, the Artemis Program is part of their “Moon to Mars” mission architecture. On Tuesday, April 18th, NASA released the outcomes from its first Architecture Concept Review (ARC 2022), a robust analysis designed to align with its overall mission strategy and define the supporting architecture. This included an Architecture Document and an executive summary that provide a detailed picture of the mission architecture and design process, plus six supporting white papers that addressed some of the biggest questions regarding exploration and architecture.

Using data from the Mars Reconnaissance Orbiter (MRO), planetary scientists have created one of the most unique and detailed maps of Mars ever. But fair warning, the biggest version of this is a could overload your computer.  

Global CTX Mosaic of Mars is the highest-resolution global image of the Red Planet ever created and it even allows you see Mars in 3D.
