Process of Undocking and Splashdown: Axiom Mission 4 Prepares for Undocking

Returning from space is a complex, carefully coordinated process involving multiple stages. For the Ax-4 crew, the journey from the International Space Station (ISS) to splashdown off the coast of California follows a precise sequence involving undocking, orbit adjustment, re-entry, parachute deployment, and recovery.

1. Final Preparations Before Undocking

Before the actual undocking, mission teams on the ground and aboard the ISS conduct a series of checks:

  • Suit Up: Ax-4 astronauts don their SpaceX pressure suits.
  • System Checks: Life support, power, propulsion, and communication systems on the Dragon spacecraft are thoroughly checked.
  • Hatch Closure: The hatch between the ISS Harmony module and the Dragon capsule is securely closed and sealed.
  • Leak Checks: Air-tightness is verified to ensure no pressure loss.

2. Undocking From the ISS

  • At the scheduled time—7:05 a.m. EDT, July 14—the SpaceX Dragon autonomously undocks from the ISS.
  • The docking mechanism at the space-facing (zenith) port of the Harmony module disengages.
  • Spring-loaded pushers gently separate the capsule from the ISS.
  • Once free, thrusters fire in a choreographed sequence to move the spacecraft safely away from the station.

This phase typically takes a few minutes, but full separation and positioning may take up to an hour.

3. Phasing Burns and Orbit Adjustment

After undocking, the Dragon performs a series of departure burns:

  • These engine firings adjust the spacecraft’s altitude and speed, moving it into a lower orbit.
  • The Dragon remains in orbit for several hours, allowing ground controllers to:
    • Finalize re-entry timing
    • Verify weather and sea conditions at the splashdown site
    • Run diagnostics on onboard systems

The duration in orbit before re-entry varies depending on mission objectives and ground recovery readiness.

4. Deorbit Burn

Once all conditions are “go” for return:

  • The spacecraft performs a deorbit burn—a critical engine firing that slows it down enough to begin descent into Earth’s atmosphere.
  • This burn typically lasts 6–12 minutes, reducing orbital velocity by about 100–150 m/s.
  • Following this, the unpressurized trunk section (containing solar panels and radiators) is jettisoned.

Only the crew capsule continues toward Earth.

5. Atmospheric Re-entry

The capsule begins re-entry at hypersonic speeds, reaching up to 28,000 km/h (17,500 mph).

  • The heat shield protects the vehicle from temperatures exceeding 1,600°C (2,900°F) caused by atmospheric friction.
  • Plasma buildup around the capsule may cause a brief blackout of communication for a few minutes.

Re-entry trajectory and timing are pre-calculated to ensure the capsule lands precisely in the designated recovery zone.

As the Dragon capsule descends:

  1. Drogue Chutes deploy around 18,000 feet (5,500 meters) to stabilize the capsule.
  2. Main Parachutes deploy around 6,000 feet (1,800 meters) to dramatically slow descent.
    • The capsule drops gently at about 25 km/h (15 mph) for a safe ocean landing.

7. Splashdown

  • The spacecraft splashes down in the Pacific Ocean off the coast of California, where recovery vessels and teams are already stationed.
  • Boats quickly reach the capsule, and divers secure it.
  • The crew remains inside as the capsule is lifted onto a recovery ship’s deck using a hydraulic lift.
  • Once secured, the hatch is opened, and medical teams assist the astronauts as they re-adapt to Earth’s gravity.

8. Post-Splashdown Procedures

  • Astronauts undergo initial medical checks and are then transported to a nearby base or facility.
  • The capsule is returned for inspection, data download, and potential reuse.
  • The mission is formally debriefed by Axiom Space, SpaceX, and NASA teams.

Shubhanshu Shukla Conducts Space Farming-Shubhanshu Shukla monitoring plant growth in a hydroponic chamber aboard the International Space Station.
Indian astronaut Shubhanshu Shukla pioneers space farming aboard the ISS to support future Mars missions and colonization.

Shubhanshu Shukla Conducts Space Farming: Introduction

As humanity prepares for long-duration missions to the Moon, Mars, and beyond, one of the greatest challenges remains how to sustainably provide food in space. Space farming—growing plants beyond Earth’s atmosphere—is no longer science fiction. Indian astronaut Shubhanshu Shukla is at the forefront of this vital research aboard the International Space Station (ISS).

In a groundbreaking initiative, Shukla is contributing to experiments focused on growing food in microgravity, a development that could transform the future of space exploration. This article delves into Shubhanshu Shukla’s role in space farming, the science behind growing plants in orbit, and how these efforts will support future interplanetary missions.

Why its Matters: Shubhanshu Shukla Conducts space farming

Supplying astronauts with food is one of the most difficult logistical challenges in space missions. Currently, food is pre-packaged and shipped from Earth, but this model becomes impractical for missions to Mars or deep space due to:

  • Limited cargo capacity
  • Food shelf-life limitations
  • Nutritional degradation over time
  • Resupply dependence on Earth

Space farming offers a long-term solution. It allows astronauts to grow fresh produce, recycle water, and even generate oxygen through plant respiration. For future colonies on the Moon or Mars, on-site food production will be essential for survival and self-sufficiency.

Shubhanshu Shukla Conducts space farming: Leading India’s Role in Space Agriculture

Shubhanshu Shukla, an Indian astronaut aboard the ISS as part of the Axiom-4 mission, is participating in experimental plant growth systems designed to simulate farming in low Earth orbit. His work contributes to global efforts by agencies like NASA, ESA, and ISRO to establish sustainable life-support systems in space.

Shukla’s background in environmental systems engineering and his training in biological sciences have positioned him perfectly for these tasks. His research is part of a larger international experiment that evaluates plant growth in conditions of microgravity, fluctuating CO₂ levels, and limited light exposure.

What Is Shubhanshu Shukla Growing in Space?

The crops chosen for space farming are typically selected based on their nutritional value, growth rate, and space efficiency. Shukla’s experiments involve:

  • Lettuce: Quick-growing and used as a model crop for space agriculture.
  • Radishes: Fast germination and ideal for root-based growth studies.
  • Wheatgrass: Offers oxygen production benefits and is easy to cultivate.
  • Microgreens: High in nutrients and suitable for confined environments.

Shukla is growing these plants in controlled growth chambers using hydroponic and aeroponic systems. These soil-less methods are more suitable for microgravity and require less mass and volume than traditional agriculture.

How Does Farming Work in Microgravity?

In space, water behaves differently due to the absence of gravity. It floats, forms bubbles, and doesn’t flow downward. This complicates the root hydration process. To address these issues, Shukla uses special root zone systems that deliver water and nutrients directly to the roots through:

  • Capillary action membranes
  • Automated misting systems
  • Nutrient delivery tubes

LED lights simulate natural sunlight by emitting specific wavelengths that promote photosynthesis. Blue light encourages leafy growth, while red light supports stem elongation and flowering.

Data Collection and Research Goals

As part of his work, Shubhanshu Shukla is responsible for:

  • Monitoring plant height, color, and health
  • Measuring water uptake and nutrient absorption
  • Capturing images at regular intervals
  • Adjusting light and nutrient variables remotely
  • Recording growth cycles and yield

These observations are sent back to Earth for detailed analysis. Scientists study the data to understand how space conditions affect plant biology at the cellular and genetic level.

Benefits of Shubhanshu Shukla Conducts space farming

1. Enhanced Food Security for Astronauts

Fresh produce offers vital nutrients that processed food lacks. Space-grown crops can help prevent conditions like bone loss, muscle atrophy, and immune suppression in long-duration missions.

2. Psychological Well-being

Gardening provides psychological benefits to astronauts, including stress relief, emotional connection, and a sense of purpose. Shukla’s interaction with the crops is part of broader behavioral studies.

3. Closed-Loop Life Support

Plants recycle carbon dioxide into oxygen and use astronaut-generated waste water. This supports closed-loop ecological systems—essential for lunar and Martian colonies.

4. Technology Transfer to Earth

Many hydroponic systems and LED technologies developed for space farming have applications in Earth-based agriculture, especially in urban and arid environments.
