NASA's New Mission: Putting Humans on Mars by the 2030s
Written on
Chapter 1: The Fascination with Mars
Mars has captured human imagination for centuries. Until fairly recently, it was believed that this mysterious planet might have once harbored life similar to that on Earth. However, the 1965 NASA Mariner 4 mission provided the first detailed visuals of Mars, unveiling a stark, lifeless environment. Despite this revelation, the quest for Martian life continues, with NASA's Perseverance and Curiosity rovers tirelessly exploring the planet's surface for any signs of life, whether ancient or contemporary.
The desire to set foot on Mars has long been a dream for humanity. While rovers provide valuable data, they can’t replicate the experience of human exploration. Fortunately, NASA has secured the funding necessary for a crewed mission to Mars! This raises several questions: What will the mission entail? When can we expect it to launch? And could this lead other countries to expedite their own Mars endeavors?
Section 1.1: Funding Approval from Congress
Recently, Congress passed a bill authorizing NASA’s funding requests. Essentially, this is how NASA seeks financial support for its projects. The government can either approve or deny these requests, establishing guidelines for how the allocated funds should be utilized. This particular bill, which spans over 1,000 pages, includes various missions and maintenance tasks. Notably, it designates funding for a Moon-to-Mars initiative. This is not merely funding for concept development; it represents a legitimate commitment to a crewed Mars mission.
Why the focus on transitioning from the Moon to Mars?
Section 1.2: The Limitations of NASA's Current Rockets
NASA’s existing rockets and spacecraft lack the capability for a direct trip to Mars. They simply don’t possess the necessary power. On the other hand, SpaceX’s Starship can achieve this with just two launches—one to transport crew and supplies into Earth’s orbit and another for refueling. The crewed Starship can then embark on its journey to Mars, landing without the need for a separate lander. Additionally, the Martian atmosphere, rich in carbon dioxide, can be utilized to produce methane and oxygen for refueling purposes, allowing for a return journey to Earth.
One might think that NASA could simply acquire a Starship for its mission. Unfortunately, the congressional bill specifies that the Moon-to-Mars mission must utilize NASA's own rockets and spacecraft. It outlines that NASA has 120 days to finalize the mission plan while adhering to these restrictions.
Chapter 2: NASA's Proposed Mission Strategy
The first video, titled "Is NASA a waste of money?" discusses the financial aspects of NASA's missions and their implications.
NASA’s Space Launch System (SLS) and Orion spacecraft, designed for such missions, lack the reusability and larger payload capacity of Starship. Therefore, orchestrating a crewed mission to Mars will be much more complex, requiring multiple launches over an extended period to transport all necessary equipment. Thankfully, NASA has devised a strategy to address this challenge.
NASA’s Artemis program aims to establish a sustained human presence on the Moon, contrasting sharply with the brief missions of the Apollo era. The plan includes constructing a significant lunar space station, known as the Lunar Gateway, which will allow astronauts to live and conduct research on the Moon's surface without extensive travel across difficult terrain.
The second video, "NASA Funded This Crazy Project To Search For Life On Mars," explores NASA's ongoing projects and ambitions regarding Mars exploration.
The Lunar Gateway will not only serve as a station but also as a staging area for the Moon-to-Mars mission. It is considerably easier to launch from the Moon than from Earth. The Gateway will house essential equipment, fuel, and supplies such as water and food.
NASA's plan involves sending multiple SLS rockets to the Lunar Gateway to stock it with the necessary resources. A final SLS launch will carry a nearly empty Orion spacecraft with just the crew, which will dock with the Gateway, refuel, and then set off for Mars.
What remains is the design of a Martian base and other mission specifics, which are still under development. We await NASA's announcement of the final mission details in about four months.
However, a crucial question lingers: When will this mission take flight? The Lunar Gateway is not expected to be operational until at least 2025, and there are many lunar scientific projects to complete before contemplating a Mars mission. Additionally, there will be a need to design, test, and develop the various components required for this mission, a process that could take several years. Realistically, the earliest launch window might be around 2030, with a more likely timeline in the mid-2030s.
This timeline presents an opportunity for SpaceX, China, and Russia to prepare their own crewed Mars missions, potentially leading to a competitive race to the Red Planet. Given the current geopolitical climate, reaching Mars could serve as a demonstration of national prowess, reminiscent of the Apollo 11 mission. Although the recent bill may appear to be merely bureaucratic paperwork, it has ignited the next space race, and the unfolding events are sure to be thrilling.
