A new study published in GeoHealth highlights the extreme dangers of Martian dust to astronauts. The dust contains silica, gypsum, perchlorates, and nanophase iron oxides, all of which could have life-threatening effects. The biggest risk is to astronauts' lungs; the fine dust is expected to remain in their lungs and be absorbed into their bloodstream, potentially causing pulmonary fibrosis, exacerbated by radiation exposure in space. Perchlorates could cause thyroid dysfunction and aplastic anemia. The study emphasizes the need for dust filtration, cabin cleaning, and electrostatic repulsion devices to avoid exposure, given the long travel time to Mars and communication delays. While acknowledging the challenges, researchers remain optimistic that these hazards are avoidable with proper preparation. The study also notes the broader impact of dust on spacecraft, vehicles, and equipment, requiring constant maintenance. Martian dust, unlike Earth dust, is composed of sharp particles, increasing the risk of lung irritation. Experts emphasize the need for sophisticated solutions, including a complete medical capability on Mars, and highlight the ethical implications of these health risks for future crewed missions.

US astronauts Butch Wilmore and Suni Williams are set to return to Earth on Tuesday after spending nine months aboard the International Space Station (ISS). Their journey home aboard SpaceX's Crew Dragon capsule, "Freedom," follows unexpected delays. Initially slated for a 10-day mission, mechanical issues with their original Boeing Starliner capsule left them stranded last June. The incident impacted Boeing's spaceflight program and necessitated a SpaceX rescue mission. Wilmore and Williams had to wait for a ride back with fellow astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov on Crew 9, after the arrival of Crew 10. Elon Musk alleged that plans to return Wilmore and Williams earlier were blocked by the Biden administration, a claim denied by officials. Their extended stay will place them sixth on NASA's single spaceflight duration list, behind Peggy Whitson. Frank Rubio currently holds the record at 371 days.

Nearly two months after a previous explosion, SpaceX launched its Starship rocket on March 6, 2025. The 403-foot rocket successfully launched from Texas, and the first-stage booster was recovered. However, minutes into the flight, the spacecraft's engines began shutting down, leading to an uncontrolled spin and loss of contact. Flaming debris was seen falling over Florida. The spacecraft reached an altitude of nearly 90 miles before the incident. SpaceX confirmed a 'rapid unscheduled disassembly' and stated that contingency responses were implemented. This was the eighth test flight, and the spacecraft was carrying mock satellites for deployment. The spacecraft did not reach the planned altitude or distance, and the planned controlled entry over the Indian Ocean did not occur. While the cause is still under investigation, SpaceX had made improvements following the previous explosion and received FAA clearance for launch. The company is aiming for Starship to eventually land astronauts on the moon and eventually Mars.

Firefly Aerospace's Blue Ghost lunar lander successfully touched down on the moon on March 2, 2025, becoming the first private company to achieve a successful, upright landing. The lander, carrying 10 NASA experiments costing $145 million, landed on the northeastern edge of the near side of the moon. The mission includes a drill to measure subsurface temperatures, a vacuum to collect moon dirt, and a device to mitigate lunar dust. Blue Ghost's journey also provided stunning images of Earth and the moon. This successful landing is part of NASA's commercial lunar delivery program, aiming to establish a lunar economy with private companies. Other private companies, including Intuitive Machines and ispace, are also vying for lunar landings, with Intuitive Machines' lander scheduled for landing on March 6th. Despite past failures by some of these companies, NASA aims to maintain a pace of two private lunar landings per year, recognizing that some missions will inevitably fail. The success of Blue Ghost represents a significant step towards a future with increased private sector involvement in space exploration.

A new lunar lander, Athena, built by Intuitive Machines, has launched toward the moon's south pole. This mission, IM-2, is particularly significant because Intuitive Machines is the first private company to successfully land on the moon. Athena, launched atop a SpaceX Falcon 9 rocket, carries a drill, a small robotic hopper (Grace), and a tiny rover to search for water ice in the south pole region. This region is crucial due to the potential for water ice, a valuable resource for future lunar exploration. The mission builds upon the success of Intuitive Machines' first lunar lander, Odysseus, which landed successfully but experienced some technical difficulties. IM-2 aims to be more ambitious with the deployment of multiple robots and a drill to collect data. Athena's journey includes a solar eclipse and a challenging landing near Mons Mouton, a plateau near the south pole offering sufficient sunlight for a 10-day mission. The lander will attempt to drill into the surface to a depth of one meter, while Grace will hop into a permanently shadowed crater to search for ice. A small rover, along with a matchbook-size rover called AstroAnt, will also explore the area. This mission represents a significant step forward in private lunar exploration, with the potential to revolutionize our understanding of the moon's resources.
