Main Article
As humanity ventures deeper into space, the need for a Space Rescue Service (SRS) is becoming more apparent. Despite the growing number of space travelers, there is currently no dedicated system to rescue stranded astronauts in the event of an emergency. Historically, rescue options were considered during the Apollo, Skylab, and Space Shuttle programs, but these lessons appear to have been forgotten in today’s era of commercial and international spaceflight.
The Boeing Starliner incident serves as a case study in the current shortcomings of space rescue infrastructure. In its first crewed mission to the International Space Station (ISS), the Starliner spacecraft faced thruster issues and helium leaks. These issues underscore the lack of comprehensive safety measures for astronaut rescue.
Unlike the ISS missions or the Space Shuttle era, today’s commercial spacecraft are privately owned and operated, making the need for a structured rescue service more urgent. Experts like Grant Cates from The Aerospace Corporation and Jan Osburg from RAND have voiced concerns about the lack of planning, saying,
“We’re not planning to do it, and you can’t do a rescue on the fly. You have to plan ahead of time.”
The Aerospace Corporation and RAND held a workshop on the 21st anniversary of the Space Shuttle Columbia disaster. Specialists from both the industry and government gathered to draft a long-term vision for space rescue.
Cates explains,
“We have multiple launch pads, multiple launch vehicles, and multiple crew-capable vehicles. But we have a gap. We’re not planning to do it, and you can’t do a rescue on the fly.”
This gap could be filled with proper legislation and congressional funding. It is clear that space rescue could prevent tragedies like Columbia and ensure the safety of astronauts on future missions to the Moon, Mars, and beyond.
A Model for Space Rescue: Submarine Rescue Analogy
A potential model for the Space Rescue Service (SRS) comes from the International Submarine Escape and Rescue Liaison Office (ISMERLO). This office was established to coordinate international submarine rescue efforts, providing a structured framework to save lives in extreme underwater environments.
Just like submarine rescues, space rescues require international coordination and collaboration. The establishment of a global space rescue organization would mirror ISMERLO’s success, enabling multiple nations to cooperate on space safety.
Table 1 below compares the structures of ISMERLO and a potential Space Rescue Service (SRS).

Beyond the technical benefits, the creation of a Space Rescue Service would encourage international goodwill. Just as countries collaborate in submarine rescue, a well-organized SRS could enhance cooperation in space, benefiting both national interests and global safety.
By leading the establishment of a global rescue system, space-faring nations would not only shape space exploration but also accrue international goodwill. A robust rescue infrastructure could also attract more private investment into space ventures, knowing that astronaut safety is a top priority.
Jared Isaacman, the commander of Polaris Dawn, stands out against Earth. He becomes the first private astronaut to go on a spacewalk. This happened on September 12, 2024. A spacewalk is when an astronaut leaves their spacecraft to work outside in space. The photo is credited to SpaceX.
Financial Viability of a Space Rescue System
One of the key hurdles in establishing a Space Rescue Service is funding. However, Osburg believes the required investment is relatively modest compared to the overall costs of space missions. He notes,
“It would take just a modest amount of money to get that ball rolling. That’s really peanuts, given the amount of money involved in space overall and also given the amount of damage that could be done if something serious were to happen.”
Table 2 illustrates the cost comparison of various space rescue efforts versus potential mission losses.

Average Cost (in millions)
Potential Damage from Mission Failure (in billions)
Given the high stakes involved, a relatively small investment in rescue services could prevent catastrophic financial losses and save lives.
The development of a Space Rescue Service is not just a matter of safety but also a matter of strategic importance. As more nations and private companies embark on increasingly ambitious space missions, a rescue service could mitigate risks, prevent tragedies, and safeguard the future of human space exploration.
From planning in advance to leveraging international collaboration, the path forward for space rescue is clear. The sooner we act, the safer our astronauts will be as they push the boundaries of exploration.

The New SpaceX Dragon Capsule Designed to De-Orbit the ISS
The International Space Station (ISS) has been a remarkable symbol of international collaboration and scientific advancement for over 25 years. Since its launch, it has hosted over 270 astronauts, cosmonauts, and commercial astronauts from various space agencies around the world. As the ISS approaches the end of its operational life, plans for its safe deorbit and disposal have been set in motion. In January 2031, a specially designed spacecraft by SpaceX, known as the U.S. Deorbit Vehicle, will undertake the critical task of de-orbiting the ISS. On July 17th, NASA held a live press conference to unveil the details of this mission, including a first look at the modified SpaceX Dragon capsule responsible for the deorbit process.
Unveiling the U.S. Deorbit Vehicle
During the press conference, NASA revealed several key features of the U.S. Deorbit Vehicle. SpaceX shared details and an image of the special Dragon via their official X account (formerly Twitter). According to SpaceX, the modified spacecraft will have six times the propellant and four times the power of today’s Dragon spacecraft. The image released shows a robust service module replacing the trunk used by the standard Crew Dragon vehicle. This new service module is larger and equipped with additional fold-out solar arrays, as well as hull-mounted solar panels, to provide the necessary power for the mission.
The modified Dragon capsule also appears to have more Draco engines than the standard Crew Dragon vehicle. The standard Crew Dragon is equipped with 18 Draco engines, each capable of generating 400 Newtons (90 lbf) of thrust, totaling 7,200 N (360 lbf) of thrust. The U.S. Deorbit Vehicle is expected to have 72 Draco thrusters arranged concentrically, capable of generating close to 30,000 Newtons (1,440 lbf) of thrust. This significant increase in thrust power is crucial for the controlled deorbit of the massive ISS structure. The image also shows the spacecraft docking with the Kibo module operated by the Japan Aerospace Exploration Agency (JAXA).
Contract and Development
NASA announced the selection of SpaceX in late June to develop the U.S. Deorbit Vehicle as part of a single-award contract valued at up to $843 million. While SpaceX is responsible for the development of the spacecraft, NASA will take ownership once it is complete and operate it throughout the mission. The spacecraft, along with the ISS, is expected to break up during re-entry, with the remains landing in the “spacecraft cemetery” in the South Pacific. The contract for the launch services has not yet been awarded but is expected to be announced shortly.
Since its launch in 1998, the ISS has served as a unique platform for scientific research and technological demonstrations that are not possible on Earth. The ISS is a collaborative effort involving five space agencies: NASA, the Canadian Space Agency (CSA), the European Space Agency (ESA), JAXA, and the Russian State Space Corporation (Roscosmos). Throughout its operational lifetime, the ISS has hosted a wide range of experiments, including studies on the effects of microgravity and space radiation on human, animal, and plant physiology. This research is crucial as NASA and its international partners plan for long-duration missions to the Moon and Mars in the coming decades.
A Symbol of International Cooperation
Beyond its scientific contributions, the ISS stands as a symbol of international cooperation and peaceful use of outer space, in line with theOuter Space Treaty and its core philosophy that “space is for all.” NASA, CSA, ESA, and JAXA have all committed to operating the ISS through 2030, while Roscosmos has committed to continue operations until at least 2028. The safe deorbit of the ISS is a shared responsibility among all five space agencies, ensuring a controlled re-entry and disposal process.
Enhanced Capabilities of the U.S. Deorbit Vehicle
The U.S. Deorbit Vehicle is a big improvement over the current Dragon spacecraft. It has six times more fuel and four times more power. This modified spacecraft can de-orbit the ISS. De-orbiting means guiding the space station back into the Earth’s atmosphere.
The vehicle has a strong service module. A service module is the part of the spacecraft that holds the main systems, like power and propulsion. It also has more solar panels to collect energy from the sun. Additionally, it comes with more Draco engines. Draco engines help the spacecraft move in space. All these upgrades are important. They help the spacecraft do its job well.
The service module is particularly noteworthy. Unlike the standard Crew Dragon vehicle, which uses a trunk for storage and supports various mission operations, the U.S. Deorbit Vehicle’s service module is larger and more powerful. The additional fold-out solar arrays and hull-mounted solar panels ensure that the spacecraft has the necessary power to sustain its systems and perform the de-orbit burn.

Draco Engines: Powering the Mission
The increased number of Draco engines is another significant modification. The standard Crew Dragon’s 18 Draco engines generate a total thrust of 7,200 Newtons (360 lbf). In contrast, the U.S. Deorbit Vehicle will feature 72 Draco thrusters, arranged concentrically, capable of generating close to 30,000 Newtons (1,440 lbf) of thrust. This substantial increase in thrust is essential for maneuvering the massive ISS and ensuring a controlled deorbit.
To put this into perspective, the standard Crew Dragon’s Draco engines are designed for precise maneuvering and controlling the spacecraft’s orientation. However, the U.S. Deorbit Vehicle’s mission requires more power to lower the ISS’s orbit and ensure it re-enters Earth’s atmosphere at the correct trajectory. The additional engines and increased thrust capacity will provide the necessary control and power for this critical operation.
Docking with the Kibo Module
The image released by SpaceX shows the U.S. Deorbit Vehicle docking with the Kibo module, a Japanese experiment module operated by JAXA. The Kibo module is one of the largest and most versatile modules on the ISS, featuring an external platform for experiments exposed to the space environment, a logistics module for storage, and an airlock for deploying satellites and other payloads. The U.S. Deorbit Vehicle’s docking with the Kibo module underscores the collaborative nature of the ISS program, involving multiple international partners.
Financial and Operational Aspects
The $843 million contract awarded to SpaceX underscores the significant financial investment in the safe deorbit of the ISS. While SpaceX is responsible for developing the U.S. Deorbit Vehicle, NASA will own and operate the spacecraft once it is completed. This arrangement highlights the collaborative effort between NASA and SpaceX, combining SpaceX’s innovative spacecraft development capabilities with NASA’s operational expertise.
SpaceX’s Role in Future Space Missions
In addition to the U.S. Deorbit Vehicle, SpaceX’s involvement in the Artemis program and the Lunar Gateway project demonstrates the company’s integral role in future space missions. The Starship HLS, developed by SpaceX, will transport astronauts to the lunar surface as part of NASA’s Artemis missions. The Artemis III and IV missions are crucial steps toward establishing a sustainable human presence on the Moon and preparing for future missions to Mars.
SpaceX’s contract to launch the core elements of the Lunar Gateway—the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO)—further cements the company’s role in NASA’s lunar exploration plans. The Lunar Gateway will serve as a space station in lunar orbit, providing support for long-term human exploration of the Moon and beyond. The Falcon Heavy rocket, which will launch the PPE and HALO into lunar orbit, is one of SpaceX’s most powerful launch vehicles, capable of carrying heavy payloads to deep space destinations.
