Health and Rehabilitation Post-Splashdown

Upon the successful culmination of the collaborative ISRO-NASA Axiom-4 mission, Gaganyatri Shubhanshu Shukla's return to Earth marked the beginning of a crucial phase of health and rehabilitation. Following his splashdown on July 15, 2025, Shukla was swiftly retrieved by SpaceX teams and subjected to immediate health evaluations to mitigate any adverse effects ensuing from prolonged exposure to microgravity. These health assessments aim to detect potential issues related to bone density, muscle mass, and cardiovascular functions that tend to degrade in a microgravity environment [source].

The rehabilitation journey continued with Shukla being airlifted to Houston, where he joined a week-long intense program designed to facilitate his body's reacclimatization to Earth's gravity. This program included comprehensive medical evaluations encompassing cardiovascular assessments, aimed at monitoring the heart's functionality post-mission, musculoskeletal tests that examined changes in muscle and bone health, and psychological debriefing sessions to address the cognitive and emotional impacts of space travel. Such rehabilitative interventions are vital for ensuring astronauts like Shukla regain optimal health and are cleared for future missions [source].

Astronauts undergo these extensive rehabilitation protocols due to the well-documented impacts of microgravity, which include bone demineralization, muscle atrophy, and cardiovascular deconditioning. Additionally, upon their return, astronauts like Shukla must recalibrate their vestibular systems, which govern balance and spatial orientation, often disrupted by prolonged weightlessness. This process is as important psychologically as it is physically, ensuring that the transition back to terrestrial life is as smooth as possible [source].

The rehabilitation program also underscores international collaboration, reflecting the joint efforts that define missions like Axiom-4. These partnerships not only advance scientific understanding but also enhance human adaptability to space environments, ultimately preparing astronauts for future endeavors. The mission's outcomes, paired with robust rehabilitative care, provide invaluable insights that shape the training and health management protocols of space agencies worldwide [source].

Impacts of Microgravity on Astronauts

The impacts of microgravity on astronauts have been a subject of intense study and research due to the significant physiological and psychological changes it induces on the human body. One of the most immediate effects observed is muscle atrophy, as the muscles used in resisting gravity on Earth become less active in a microgravity environment. This leads to a decrease in muscle mass and strength, which can pose challenges for astronauts during and after space missions. Understanding these effects is crucial, as demonstrated in the ISRO-NASA Axiom-4 mission, where astronauts underwent comprehensive health checks and rehabilitation upon return to address these changes [0](https://www.isro.gov.in/ISRO_NASA_Axiom4_mission_post_splash_down_activities.html).

Additionally, astronauts in microgravity experience bone density loss, akin to osteoporosis, at a much more accelerated rate. This occurs because bones no longer support body weight as they do on Earth, leading to calcium loss and weakening. The rehabilitation programs for astronauts like Gaganyatri Shubhanshu Shukla, who returned from the Axiom-4 mission, often include musculoskeletal tests to monitor recovery from such conditions [0](https://www.isro.gov.in/ISRO_NASA_Axiom4_mission_post_splash_down_activities.html).

Beyond the physical impacts, microgravity also affects the cardiovascular system. In the absence of gravity, blood and other body fluids tend to move upwards, which can lead to fluid shifts and pressure on the eyes and optic nerves, potentially causing visual impairments. Moreover, cardiovascular deconditioning is another concern, requiring astronauts to engage in regular exercise regimens to maintain their heart health during space missions.

Psychologically, the experience of microgravity can influence mental well-being. The isolation and confinement of space, combined with the challenges of living in a zero-gravity environment, can lead to psychological stress. As part of their rehabilitation, astronauts undergo psychological debriefing to help them reintegrate mentally and emotionally upon their return to Earth. This was an integral part of the post-mission activities for those returning from the ISRO-NASA Axiom-4 mission [0](https://www.isro.gov.in/ISRO_NASA_Axiom4_mission_post_splash_down_activities.html).

Key Collaborative Efforts and Related Missions

The collaboration between NASA and ISRO has led to several successful missions, one of which is the Axiom-4 mission that involved Indian astronaut Gaganyatri Shubhanshu Shukla. This mission to the International Space Station (ISS) marks a significant milestone in international cooperation in space exploration. Upon successfully returning to Earth on July 15, 2025, Shukla was recovered by SpaceX and underwent intensive health checks before being transported to Houston for further rehabilitation. This collaboration, detailed in an ISRO statement, underscores the shared goals of advancing human space missions and enhancing scientific research capabilities.

A key highlight of this mission was the extensive rehabilitation program Shukla participated in after splashdown. This program included medical checks, musculoskeletal assessments, and psychological debriefing to mitigate the effects of microgravity on his body. The lessons learned from this mission are expected to bring about enhancements in astronaut training, mission operations, and the human-hardware-software interface. The impact of these findings is crucial for the upcoming Indian Gaganyaan mission, as stated by ISRO Chairman V Narayanan during a post-mission briefing.

Apart from the Axiom-4 mission, efforts like the upcoming NASA-ISRO Synthetic Aperture Radar (NISAR) satellite aim to enhance the observation of Earth's ecosystems and the dynamics of natural events. Scheduled for launch in late July, the NISAR project exemplifies further collaboration between these agencies and signifies an ongoing commitment to leveraging space technology for Earth-focused applications. This mission was highlighted in a NASA news conference, emphasizing the strategic goals of both agencies in addressing climate challenges.

The SpaceX Crew-11 mission, planned for a July 31st launch, epitomizes continued joint efforts in space exploration. Much like the collaborative Axiom-4 mission, Crew-11 will ensure the continued presence of humans aboard the ISS, furthering research and technological advancements. Such endeavors not only bolster the relationship between NASA and its partners including India but also sustain the momentum of human exploration in space, showcasing the efficiency and efficacy of multinational space missions.
