## NASA Prepares for CRS‑33 Dragon Departure from the ISS

NASA will broadcast the departure of SpaceX’s 33rd Commercial Resupply Services (CRS‑33) mission as the Dragon spacecraft undocks from the International Space Station (ISS) and returns to Earth. Scheduled for Thursday, Feb. 26, the coverage begins at 11:45 a.m. EST on NASA’s streaming platforms, including NASA+.

The Dragon capsule will carry scientific research samples, experimental hardware, and station equipment back for post-flight analysis. These return missions are an essential part of ISS operations, enabling scientists to study how microgravity affects biological, physical, and technological systems.

The departure marks the end of another routine, yet scientifically critical, cargo rotation that keeps experiments flowing between Earth and space.

## What the CRS‑33 Dragon Is Bringing Home

NASA has not released the full manifest of return cargo, but the agency confirmed that the capsule will carry sealed scientific samples and research hardware from multinational investigations aboard the ISS. Typically, returning missions include:

• Biological samples exposed to microgravity
• Materials science experiments requiring Earth‑based lab analysis
• Technology demonstration components
• Used hardware for refurbishment or diagnostic review

One advantage of SpaceX’s Dragon spacecraft is its ability to return large quantities of cargo safely to Earth, something no other current commercial cargo vehicle can do. While exact masses and experiment names for CRS‑33 have not been publicly detailed, recent return missions have averaged more than 1.5–2 tons of cargo.

## Why Returned Science Matters

The ISS functions as both a laboratory and an engineering testbed. Many experiments initiated in orbit cannot be fully analyzed until they arrive back on Earth. Dragon provides the means to complete the research cycle.

Returned samples often support long‑running studies in:

• Human health and physiology
• Pharmaceutical development
• Fluid and combustion physics
• Space‑based manufacturing
• Agricultural research
• Radiation exposure analysis

Microgravity reveals processes normally obscured by gravity on Earth. Returning these samples extends the usefulness of orbital experiments, helping researchers understand phenomena ranging from protein crystal formation to the durability of spacecraft materials.

## How the Undocking and Departure Process Works

The departure sequence for a Dragon cargo mission is well established:

1. **Hatch closure** – ISS crew closes the hatch leading to the Dragon capsule, followed by leak checks.
2. **Undocking** – Ground controllers command the spacecraft to release from the Harmony module’s forward port.
3. **Departure burns** – A series of small thruster firings guide Dragon safely away from the ISS.
4. **Deorbit** – After several hours of free flight, a targeted deorbit burn begins Dragon’s descent toward Earth.
5. **Splashdown** – The capsule lands off the U.S. coast, where recovery teams retrieve it for transport to NASA facilities.

NASA has not yet published the targeted splashdown zone for CRS‑33, but past missions have landed in the Atlantic or Gulf of Mexico depending on weather and sea conditions.

## What Happens After Dragon Lands

Once Dragon is recovered, time‑sensitive samples are transferred to cold storage and flown directly to laboratories for processing. This rapid turnaround is crucial for biological studies that change quickly after returning to Earth’s gravity.

Other hardware is returned to NASA centers and partner institutions for inspection. Some equipment may be serviced and sent back to space on a later mission.

The remainder of the spacecraft’s contents undergo scheduled analysis as part of NASA’s overall ISS research pipeline, with scientists publishing findings over the following months or years.

## The Role of Commercial Resupply Missions

The CRS program is part of NASA’s broader strategy to use commercial spacecraft to support the ISS. SpaceX currently operates two versions of Dragon: a crewed variant and the cargo version used for CRS missions.

Cargo Dragons can stay docked for extended periods, providing flexible scheduling for loading and logistics. They also feature:

• Pressurized and unpressurized cargo capability
• High downmass capacity
• Automated docking
• Reusability

The success of the CRS program has proven essential for sustaining long-duration scientific operations aboard the ISS.

## Why CRS‑33 Matters in 2026

Although CRS‑33 is one mission in a long line of resupply flights, each departure represents a key moment in the station’s science cycle. With increasing emphasis on biological and materials research relevant to deep‑space exploration, sample return missions help NASA prepare for crewed journeys farther from Earth.

The mission also continues the partnership between NASA, SpaceX, and international agencies that rely on the orbiting laboratory. As the ISS enters its late operational phase, maintaining this cadence of supply and return flights will be critical to maximizing scientific output before commercial stations take on more of the workload.

## How to Watch NASA’s Coverage

NASA will stream the CRS‑33 undocking and departure on:

• NASA+
• NASA TV
• The NASA app
• NASA’s website

Coverage begins at 11:45 a.m. EST on Feb. 26. Undocking typically occurs shortly after the broadcast starts, though schedules can shift depending on internal ISS preparations and orbital conditions.

## Looking Ahead

After CRS‑33 departs, NASA and partners will prepare for upcoming cargo and crew missions later in the year. Each mission brings a unique set of experiments, technology tests, and operational tasks that keep the ISS productive.

For now, the CRS‑33 return represents another step in maintaining the flow of scientific data between Earth and orbit, ensuring that the ISS continues to serve as a proving ground for future exploration missions.
