Although they are thought of as rare, meteorites are actually quite common. About 40,000 tons of meteorites strike Earth every day. Most of them land in the ocean, and most are quite tiny, but they are still common enough that hobbyists all over the world find meteorites all the time. The most common place to find them is in arid regions where their coloring can stand out from the terrain. But even then a meteorite can be difficult to distinguish from terrestrial rocks.

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.

The International Space Station (ISS) is nearing the end of its service. While NASA and its partners have committed to keeping it in operation until 2030, plans are already in place for successor space stations that will carry on the ISS’ legacy. China plans to assume a leading role with Tiangong, while the India Space Research Organization (ISRO) plans to deploy its own space station by mid-decade. NASA has also contracted with three aerospace companies to design commercial space stations, including Blue Origin’s Orbital Reef, the Axiom Space Station (AxS), and Starlab.

Well, buckle up! The European multinational aerospace giant Airbus has thrown its hat into the ring! In a recently-released video, the company detailed its proposal for a Multi-Purpose Orbital Module (MPOP) called the Airbus LOOP. This modular space segment contains three decks, a centrifuge, and enough volume for a crew of four, making it suitable for future space stations and long-duration missions to Mars. The LOOP builds on the company’s long history of human spaceflight programs, like the ISS Columbus Module, the Automated Transfer Vehicle (ATV), and the Orion European Service Module (ESM).

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.

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 has a long history of crowdsourcing solutions, seeking input from the public, entrepreneurs, and citizen scientists. Currently, the agency is tasked with preparing for the long-awaited return to the Moon (the Artemis Program) and addressing the growing problem of Climate Change. The former entails all manner of requirements, from launch vehicles and human-rated spacecraft to logistical concerns and payload services. The latter calls for advances in climate science, Earth observation, and high-quality data collection.

To enlist the help of entrepreneurs in addressing these challenges, NASA’s Science Mission Directorate (SMD) has once again teamed up with the world-leading crowdsourcing platform HeroX to launch the NASA Entrepreneurs Challenge. With a total prize purse of $1,000,000, NASA is looking for ideas to develop and commercialize state-of-the-art technology and data usage that advances lunar exploration and climate science. The challenge launched on April 10th and will run until November 29th, after which the winners will be invited to a live pitch event hosted at the Defense TechConnect Innovation Summit and Expo in Washington, D.C.

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

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.

On Thursday, March 30th, NASA’s Perseverance rover drilled and stored the first rock core sample of its newest science campaign. This is the sixteenth sample the rover has taken as part of the ambitious Mars Sample Return (MSR) mission, a collaborative effort between NASA and the European Space Agency (ESA) to retrieve Perseverance’s samples and bring them back to Earth. Once they arrive (expected to happen by 2033), scientists will analyze them using state-of-the-art machinery too heavy and cumbersome to send to Mars as part of a robotic mission.

The China National Space Agency (CNSA) has made considerable progress in recent years with the development of its Long March 5 (CZ-5) rocket and the completion of its Tiangong-3 space station. The agency also turned heads when it announced plans in June 2021 to create an International Lunar Research Station (ILRS) that would rival the Artemis Program. On top of all that, China upped the ante when it announced later that month that it also had plans to send crewed missions to Mars by 2033, concurrent with NASA’s plans.

As part of their growing efforts to become a major power in space, which includes human exploration, China recently announced the completion of the first in-orbit test of a Stirling thermoelectric converter. The Shenzou-15 mission crew performed the test aboard Tiangong-3, and it was the first successful verification of the technology in space. This technology is also being investigated by NASA and is considered a technological solution to the challenges of space exploration, especially where long-duration stays and missions to locations in deep space are concerned.
