History of Space Elevator Competitions

2005

First Centennial Challenges

In 2005, NASA partnered with the Spaceward Foundation to launch the first Centennial Challenges, offering $400,000 in prize money to accelerate innovation in space technologies. The program’s debut featured two competitions: the Tether Challenge, focused on developing ultra-strong, lightweight materials, and the Beam Power Challenge, aimed at advancing wireless power systems for climbing robotic devices. These challenges supported futuristic goals like space elevators and solar power satellites, while promoting hands-on innovation in materials science and power transmission.

2006

Bigger Prizes, Global Interest

Building on the success of the inaugural 2005 competition, the 2006 Space Elevator Challenge expanded significantly, with prize money tripling to $400,000 through NASA’s Centennial Challenges program. Held in Mountain View, California, the event attracted growing interest from top universities, including MIT and Virginia Tech. Once again, the competition focused on two key technologies for space elevator development: ultra-strong tethers and wireless power transmission. With stronger teams and higher stakes, the 2006 challenge helped solidify the Space Elevator Games as a serious platform for advancing futuristic space infrastructure.

2007

Higher Stakes, Higher Climbs

The 2007 Space Elevator Games raised the bar both literally and technically. With the racecourse extended to 100 meters and a prize of $500,000, climbers now had to ascend at 2 m/s to qualify. Teams from Canada, the U.S., and Japan competed using lasers, searchlights, and even microwaves, but none met the target speed. The University of Saskatchewan team again came closest, reaching 1.8 m/s. Meanwhile, the tether competition saw MIT’s Delta-X enter the first carbon nanotube tether, but no prize was awarded.

August 2009

Japan Launches Its Own Climber Challenge

In August 2009, the Japan Space Elevator Association (JSEA) held its first technical and engineering competition, JSETEC. Teams competed to build the fastest battery-powered climbers, which ascended a 150-meter-long, 50mm-wide tether suspended by a helium balloon. Despite wind and weather challenges—common to outdoor Climber competitions—each team managed at least one run per day. With diverse designs on display, the event offered early glimpses into real-world climber development. JSEA announced plans to double the climb height each year and refine the competition rules, setting the stage for an ambitious future in space elevator innovation.

A Breakthrough at Last

After a year’s pause, the 2009 Games delivered the first major victory. Held at NASA Dryden Flight Research Center, the Power Beaming Challenge featured a 1-kilometer course with a $2 million prize. LaserMotive became the first team to succeed, winning $900,000 for a 3.95 m/s climb. Attempts to reach the higher prize threshold of 5 m/s fell short. The Strong Tether Challenge, now offering $2 million, saw a carbon nanotube entry from Japan’s Shizuoka University, but it failed to beat the benchmark, and no prize was awarded.

August 2010

Japan’s JSETEC Returns with Record Speed

The Japan Space Elevator Association (JSEA) hosted its second JSETEC competition in 2010, drawing 15 teams and 16 climbers. Despite tough conditions, teams completed up to three runs each. Kanagawa University won the overall title, recognized for reliability and safety, even if not the fastest. A highlight came from the University of Saskatchewan team, whose climber reached an incredible 18.3 m/s before crashing—an unofficial but stunning performance. Looking ahead, JSEA announced plans for more frequent climb events to push technological progress and lower participation costs. The event cemented JSETEC as a serious and evolving player in space elevator development.

June 2011

First European Space Elevator Challenge

In 2011, Europe launched its first space elevator competition: the European Space Elevator Challenge (EuSEC). Organized by WARR at the Technical University of Munich with support from EuroSpaceward and other partners, EuSEC emphasized ecological design, efficiency, and alignment with real space elevator concepts. Held at TUM’s Garching campus in June, the competition awarded prizes for technical innovation, with a top prize of €2,000. At the same time, Japan hosted its own JSETEC competition, continuing its annual effort to advance climber design. With these parallel events, space elevator competitions expanded their global reach and further energized the international development community.

Strong Tether Challenge Returns, Still No Winner

At the 2011 Space Elevator Conference, the Strong Tether Challenge once again tested the limits of material strength. Organized by the Spaceward Foundation under NASA’s Centennial Challenges program, this year’s event featured two entries: one from newcomer Flint Hamblin and another from veteran team Odysseus Technologies. While Hamblin’s tethers—made from off-the-shelf materials—offered baseline data for future attempts, Odysseus’ carbon nanotube tether broke well below expectations. No prize was awarded, continuing the challenge’s streak of elusive victories. Still, growing interest from university research groups hinted at stronger contenders on the horizon.

2012

Higher Ambitions, Mixed Results

In 2012, space elevator competitions pushed boundaries in both Japan and Europe. Japan’s JSETEC set its most ambitious goal yet—a 1,200-meter climb on Mt. Fuji in Shizuoka—but despite participation from 16 teams, no climber successfully completed the full ascent. The challenge highlighted the growing scale and technical difficulty of long-range tether climbs. Meanwhile, Europe held its second EuSEC event at the Technical University of Munich in October. Six teams competed on a 50-meter course, continuing the focus on practical climber engineering using rope or belt tethers. While Japan tested the limits of altitude, Europe remained grounded in refining core technologies.

Japan Reaches New Heights at SPEC2013

In August 2013, Japan’s fifth Space Elevator Challenge (SPEC2013) marked a major milestone in vertical tether experimentation. Building on efforts that began with 150-meter climbs in 2009, the competition successfully deployed a tether suspended by balloon to a full 1,200 meters—its original goal. For the first time, a climber ascended and descended along the tether, reaching an altitude of 1,100 meters. This achievement represented a significant technical leap and demonstrated the increasing realism and scale of Japan’s space elevator test campaigns.

Innovation from Israel’s Technion Competition

In 2014, the Technion Institute in Israel hosted a creative and accessible space elevator competition. The winning climber stood out by using the motor from an electric screwdriver - an idea inspired by plastic extrusion techniques from the manufacturing world. This clever reuse of everyday engineering highlighted how simple, practical thinking can drive innovation. The event added a fresh perspective to the global space elevator scene, showing that impactful ideas can come from modest setups and hands-on experience.

Japan’s SPEC Hits New Climbing Records

The 2014 Space Elevator Challenge (SPEC2014) in Japan ran from August 6–9 and delivered some of the most impressive results in the competition’s history. Several teams achieved climbs exceeding 1,000 meters on balloon-suspended tethers. Notably, Team Okuzawa completed a full 1,200-meter round trip—the longest recorded ascent and descent to date. Multiple teams from Kanagawa University’s Egami Lab also reached between 1,100 and 1,200 meters, and Germany’s Technical University of Munich made a strong showing with a 1,000-meter climb before their climber stopped midair. The event clearly demonstrated rapid progress in long-distance tethered climbs.

SPEC Adds Creative Challenges in Urban Mito

The 9th Space Elevator Challenge (SPEC2017) took place in Mito City, Japan, with around 20 teams testing climbers on 200-meter tethers suspended by balloons. Teams from Japan and abroad, including Germany’s Technical University of Munich, showcased innovative designs - ranging from carbon-fiber builds to climbers-within-climbers concepts. A new mission challenge added playful complexity: transporting upright dolls without tipping them over. While none succeeded, the task was a highlight. For the first time, Mito Mayor’s Awards were given for speed (TUM), payload (4th Laboratory), and mission execution (Team Okuzawa), blending serious tech with fun experimentation.
