Lunar Space Elevator Could Cut Moon Mission Costs by Two-Thirds Using Existing Technology
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A lunar space elevator called the ‘spaceline’ could drastically reduce space travel costs by enabling fuel-efficient transport between Earth and the Moon using currently available materials.
📈 One key stat: The spaceline could slash lunar mission fuel requirements to just one-third of current levels, making space exploration significantly more affordable and sustainable.
💬 One key quote: “By extending a line, anchored on the Moon, to deep within Earth’s gravity well, we can construct a stable, traversable cable allowing free movement from the vicinity of Earth to the Moon’s surface,” explain researchers Penoyre and Sandford.
1️⃣ The big picture: Scientists have proposed a revolutionary ‘spaceline’ concept that could transform space travel economics. Unlike traditional Earth-anchored space elevator designs, this lunar space elevator would extend from the Moon toward Earth, stopping just outside our atmosphere. The design takes advantage of the Lagrange point where Earth and Moon’s gravitational pulls balance each other, significantly reducing tension on the cable. What makes this concept exciting is that it appears feasible with existing materials like carbon polymers, potentially costing several billion dollars – comparable to other major space missions. Here is an article detailing a spaceline concept to transform space travel economics.
2️⃣ Why is this good news: This innovation could dramatically cut the cost barrier that has limited our space exploration capabilities for decades. By reducing fuel requirements to a third of current levels, the spaceline makes regular Moon missions economically viable for more stakeholders. The cable would provide unprecedented access to the Lagrange point, an ideal location for construction and scientific research due to its stable gravitational properties and minimal space debris. This stable platform could host telescopes, particle accelerators, and serve as a launchpad for deep space missions. Most importantly, the concept doesn’t require future technologies – it’s achievable with materials and engineering methods available today.
3️⃣ What’s next: Researchers must now develop detailed engineering plans and secure funding for this multi-billion dollar project. Material testing under space conditions will need to verify that carbon polymers can withstand the stresses involved. Once built, the spaceline could quickly become the foundation for a permanent human presence beyond Earth orbit.
