Perseverance is NASA’s largest and most advanced rover, equipped with 7 different scientific instruments for conducting high-resolution imaging, mineralogy, and chemical analysis. Its mission is to explore Jezero Crater, the site of a 28-mile-wide impact site that is believed to have once contained an ancient delta formed by a river flowing into a lake billions of years ago.
Ingenuity Mars Helicopter
Ingenuity, a small robotic helicopter, hitched a ride to Mars attached to the Perseverance rover. In April 2021, Ingenuity conducted the first powered, controlled flight on another planet. Its five successful test flights demonstrated that powered, controlled flight is possible on Mars, opening up possibilities for more aerial exploration on future missions. While Ingenuity’s mission is a technology demonstration, data collected during its short life will provide valuable insights for the development of more advanced Mars aircraft.
With these groundbreaking missions underway, the future of Mars exploration looks bright. Perseverance and Ingenuity are poised to reveal new discoveries about Mars’ potential to harbor life and the possibilities for aerial exploration and eventual human missions to the Red Planet. Space agencies around the world are pioneering innovative new technologies to uncover the secrets of Mars and expand the boundaries of human achievement.
Upcoming Mars Missions: Sample Return and Future Human Exploration
Upcoming Mars missions aim to achieve major milestones in the exploration of the red planet. Two of the most ambitious goals are returning rock and soil samples to Earth for in-depth analysis and eventually sending humans to explore the Martian surface.
Mars Sample Return
NASA and ESA are collaborating on missions to collect rock and soil samples on Mars and return them to Earth. The first step is the Mars 2020 rover, which will cache samples in tubes and deposit them on the surface for future retrieval. Planned for launch in 2020, the rover will
search for signs of ancient life and collect samples that could contain clues to Mars’ potential habitability. Subsequent missions propose to retrieve the cached samples and launch them into Mars orbit. An orbiter would then capture the samples and return them to Earth in the 2030s.
Studying pristine Martian samples in Earth-based laboratories could transform our understanding of Mars’ geological and biological history. However, returning samples to Earth is an engineering challenge that has never been achieved. If successful, it would represent a giant leap in Mars exploration.
Human Missions to Mars
Sending the first humans to Mars has been a long-held goal for space agencies and private companies. NASA aims to achieve this in the 2030s through the Artemis program. Artemis includes robotic and human missions to explore more of the lunar surface in preparation for crewed missions to Mars. Key challenges for human Mars missions include the health effects of long-duration spaceflight, growing food, and producing fuel for the return trip.
Establishing a long-term human presence on Mars is the ultimate vision for SpaceX and other private space companies. Their futuristic concepts include building cities and terraforming the planet to make its atmosphere breathable for humans. While still far-fetched, rapid progress in space technology could help make human colonization of Mars a reality within the next 50 to 100 years. With each small step, we get closer to this giant leap.
Other Planets and Moons Targeted for Exploration
As we continue to explore the mysteries of space, other planets and moons are now in our sights. Advancements in rocketry and spacecraft technologies have made interplanetary travel more feasible, allowing us to send probes and rovers to investigate worlds beyond our own.
