NASA and the China National Space Agency (CNSA) are planning to send astronauts to Mars as early as the next decade, but the journey comes with significant challenges. One of the key concerns is the effect of Martian gravity on the human body, particularly on skeletal muscle. Martian gravity is about 38% of Earth's, which could lead to long-term health risks.
What Happened
An international team of researchers is currently studying how Martian gravity will affect skeletal muscle, which is essential to movement and metabolic health. The study aims to anticipate and prepare for potential challenges that astronauts may face on the red planet.
Meanwhile, a Russian cargo spacecraft, Progress 94, launched towards the International Space Station on March 22, carrying nearly 3,000 pounds of food, fuel, and supplies for the Expedition 73 crew.
Why It Matters
NASA's latest discoveries on Mars are also shedding light on the planet's potential for life. The discovery of a buried delta on Mars, found by the Perseverance rover, suggests that water once flowed on the planet. This finding boosts the search for life on Mars and provides valuable insights into the planet's history.
What Experts Say
"LRAs are the most efficient and cost-effective way to improve products that come out of GPS," said Lucia Tsaoussi, program manager for NASA's Space Geodesy at NASA Headquarters in Washington. NASA's laser reflecting technology, which was launched aboard GPS III SV-09, is now operational and will aid Global Positioning System (GPS) accuracy.
Key Facts
- Who: NASA, China National Space Agency (CNSA), and Russian space agency
- What: Planning to send astronauts to Mars, studying effects of Martian gravity on skeletal muscle, and launching cargo spacecraft to the International Space Station
- Impact: Potential for life on Mars, improved GPS accuracy, and long-term health risks for astronauts
What Comes Next
As NASA and other space agencies continue to explore Mars and the Moon, the need to protect our heritage on these celestial bodies becomes increasingly important. With over 100 metric tons of human-made material already on the Moon's surface, the next decade is expected to see over 100 new lunar missions, equaling or exceeding all previous missions. This raises concerns about how to protect the history of space exploration.
