## NASA Plans Accessible Artemis Webinar for Blind and Low-Vision Audiences

NASA is scheduled to host a virtual public webinar focused on the powerful RS-25 rocket engines used by the Space Launch System, or SLS, the launch vehicle designed for Artemis lunar missions.

The event, titled *“The RS-25 Engine and the Future of Artemis Missions: An Accessible Webinar for the Blind and Low-Vision Community,”* is set for 2 p.m. EDT on Friday, October 2, 2026. NASA says the webinar will run for approximately two hours.

Although the session is open to anyone, it has been tailored specifically for blind and low-vision participants. That focus matters because space exploration is often communicated through dramatic launch footage, diagrams, animations, and spacecraft imagery. An accessible presentation can help ensure that the technical story behind a lunar mission is understandable without relying solely on visuals.

NASA’s announcement identifies the RS-25 engine and Artemis mission future as the webinar’s central subjects. It does not, however, provide a detailed agenda, a confirmed speaker list, or specific information about the accessibility tools that will be used during the event. Participants should consult NASA’s event information closer to the date for registration and access details.

## Why the RS-25 Engine Is Central to Artemis

The RS-25 is a liquid-fueled rocket engine with a long history in American human spaceflight. Earlier versions of the engine powered NASA’s Space Shuttle program for three decades. For Artemis, four RS-25 engines are mounted at the bottom of the SLS core stage.

Together, these engines provide much of the thrust needed to lift the massive rocket away from Earth. They burn liquid hydrogen and liquid oxygen, a propellant combination known for high efficiency but also for demanding engineering requirements. Liquid hydrogen must be kept at extremely low temperatures, while the engines must operate reliably amid intense heat, vibration, pressure, and acceleration during launch.

The engines work alongside two solid rocket boosters attached to the SLS core stage. While the boosters deliver a major burst of thrust during the first part of ascent, the RS-25 engines continue operating as the vehicle heads toward space.

This propulsion system is intended to send NASA’s Orion spacecraft, crews, cargo, and other hardware beyond low-Earth orbit. Artemis missions are aimed at returning astronauts to the vicinity of the Moon and supporting a longer-term lunar exploration program.

## A Shuttle Legacy Adapted for a New Rocket

The RS-25 is notable because it connects the Space Shuttle era to NASA’s current deep-space ambitions. Engines used on early SLS flights draw on hardware and expertise developed for the shuttle program, though they have required changes for their new role.

A Space Shuttle launched its main engines while attached to an orbiter and external tank, then returned the engines for refurbishment after each mission. SLS uses the engines in a different configuration and on a vehicle intended for deep-space launches rather than missions to low-Earth orbit.

NASA and its contractors have tested and upgraded RS-25 systems for SLS conditions. The engines must work with new flight software, updated controllers, a different core stage, and a mission profile that places different demands on the propulsion system.

Future RS-25 engines are also being manufactured with production methods designed for SLS needs. This includes efforts to simplify certain components and improve manufacturing efficiency while maintaining the performance and reliability standards required for human-rated exploration missions.

## What Artemis Is Designed to Do

Artemis is NASA’s broad program for lunar exploration. Its architecture includes the SLS rocket, Orion spacecraft, ground systems at Kennedy Space Center, lunar landers, spacesuits, commercial partners, and international contributions.

The program’s first integrated flight, Artemis I, launched an uncrewed Orion spacecraft around the Moon in 2022. That mission demonstrated the combined SLS and Orion system in space and provided important data for subsequent missions.

Future Artemis flights are expected to build toward crewed lunar missions. NASA’s plans have evolved over time, and mission dates, vehicle readiness milestones, and hardware configurations can change as testing and safety reviews continue. The agency’s overall objective is to establish the capabilities needed for sustained lunar exploration, including missions that can support scientific work and prepare for eventual human exploration of Mars.

For the public, the RS-25 webinar offers a chance to examine one of the most technically consequential pieces of that architecture: the engine system responsible for beginning the journey.

## Accessibility Is Part of Public Space Exploration

NASA’s decision to tailor a technical Artemis session for blind and low-vision audiences reflects a broader accessibility challenge in science communication.

Rocket engines and mission planning are often explained with cutaway illustrations, telemetry plots, launch videos, and computer animations. Those materials can be valuable, but they may not be sufficient on their own for people who do not access visual information in the same way.

A webinar designed with a blind and low-vision community in mind can put greater emphasis on precise verbal descriptions, understandable explanations of physical systems, and opportunities for participants to ask questions. It can also help frame complex concepts—such as thrust, combustion, cryogenic propellants, and launch staging—in ways that do not depend on a diagram.

NASA’s source announcement does not specify whether the session will include live audio description, captioning, transcripts, accessible slide materials, sign-language interpretation, or other services. Those details should not be assumed. Still, the event’s stated audience indicates that accessibility is a core part of its intended design rather than an afterthought.

## Why This Webinar Matters

Artemis is frequently discussed in terms of astronauts, Moon landings, and large spacecraft. But missions begin with propulsion. The RS-25 engine is a useful lens through which to understand the scale of the challenge: a lunar mission depends on years of testing, manufacturing, ground operations, software development, and carefully controlled combustion occurring within seconds of liftoff.

The webinar also has significance beyond its engineering subject. Public participation in space exploration should include people with different access needs. When agencies develop programming for communities that are often excluded by visual-first science communication, they make the story of exploration more complete.

NASA’s planned session will not answer every question about the future schedule of Artemis or the technical development of SLS. Those programs remain complex and subject to ongoing assessments. But it should provide an accessible introduction to a critical component of NASA’s lunar transportation system and the role it may play in missions beyond Earth orbit.

## What Is Known and What Is Not Yet Confirmed

NASA has announced that the webinar will be held virtually at 2 p.m. EDT on Friday, October 2, 2026, and will last about two hours. It will be open to the public and tailored for blind and low-vision participants. Its stated topic is the RS-25 engine and the future of Artemis missions.
