Florida: NASA astronauts Sunita Williams and Butch Wilmore, who returned to Earth on early Wednesday after spending nine months in space, will undergo a 45-day rehabilitation program to help them readjust to Earth's gravity.

According to NASA, the astronauts are expected to undergo an extensive rehabilitation program which is planned to be scheduled for two hours a day. The Astronaut Strength, Conditioning, and Rehabilitation (ASCR) program will begin on landing day and consists of three phases: an initial focus on mobility and muscle strengthening, followed by proprioceptive exercises and cardiovascular conditioning, and finally, the third and longest phase, which will focus on functional development.

According to an earlier research by NASA, the astronauts tend to face numerous health issues such as dizziness, nausea, bone loss, and weakened muscles.

While astronauts typically regain normal fitness levels within 45 days, recovery time varies based on individual physiology, sometimes taking months or even years.

As per NASA, the four astronauts of the Crew-9 mission will undergo various medical procedures before the rehabilitation program begin.

The program is customised for each astronaut based on test results, medical status, and mission roles.

Mumbai (PTI): The Maharashtra government has set up a State Vaccination Task Force to strengthen the regular immunisation programme and review the progress of related campaigns, a health department official said on Monday.

The State Vaccination Task Force will comprise at least 29 members and will be headed by the administrative head of the health department, he informed.

The government has also constituted separate district-level and municipal vaccination task forces to improve implementation and address challenges at the grassroots level, he said.

Municipal task forces, chaired by respective civic commissioners, have been constituted in view of the vast urban population in Maharashtra and the role of civic bodies in implementing different health programmes.

The district-level task forces will function under the chairmanship of collectors.

"Complete immunisation of children at the appropriate age is an extremely simple, cost-effective and highly effective measure to reduce child mortality and the prevalence of diseases among kids. Immunisation is a powerful tool for reducing illness in children," maintained the official.

To ensure full vaccination of all children, the state government implements various campaigns from time to time as per the central government guidelines, he pointed out.

"Active participation and cooperation of other relevant government departments are essential (in making these campaigns successful)," according to the official.

The state-level body will review the regular immunisation programme, associated campaigns and vaccine-preventable diseases in detail. It will also conduct focused assessments of high-risk districts and municipal corporations, including vacancies at district, municipal and sub-district levels, availability of cold chain equipment, resource gaps and training requirements, he noted.

The state task force will review allocation and utilisation of funds for immunisation and ensure timely action by officers concerned based on reports from district and municipal task forces and state-level monitoring mechanisms, the official said.

It will also ensure active coordination and participation of other government departments in immunisation drives, while district and municipal task forces will carry out similar functions at their respective levels, the official added.
