Sharad Pawar discharged from Pune hospital; advised rest for few days
Pune (PTI): NCP (SP) chief Sharad Pawar, admitted to a hospital here with dehydration, was discharged on Wednesday morning, with doctors saying he is doing fine.
The 85-year-old Rajya Sabha member was admitted to the Ruby Hall Clinic in Pune on Sunday following complaints of dehydration.
"He is doing well. He has been given discharge, and he has already left for Mumbai. He has been advised to take rest for the next couple of days before resuming his normal routine," said Dr Purvez Grant, the chief cardiologist, chairman and managing trustee of the private hospital.
Earlier, the former Union minister was admitted to the same hospital on February 9 following a chest infection and was discharged on February 14.

Space-Siren’s Call: Why Artemis 2 is Returning to the Hangar
In the latest setback for the Artemis 2 mission, NASA said on Saturday that it will move the Space Launch System (SLS) rocket and the Orion spacecraft back to the Vehicle Assembly Building (VAB) starting February 24. Because of this delay, the first crewed Moon mission since Apollo 17 will now happen no earlier than April.
Just one day earlier, NASA had said it was ready to launch Artemis 2 as soon as March 6, after successfully completing a second wet dress rehearsal (a full fueling test and practice countdown) on February 19. However, on February 21, engineers found a problem when the helium supply to the rocket’s upper stage was unexpectedly interrupted.
Helium is used to keep pressure inside the rocket’s liquid hydrogen and liquid oxygen tanks. Without this pressure, the fuel cannot properly flow to the engine, which is needed to push the Orion spacecraft toward the Moon.
It is important to note that the helium system was working fine during the main practice test. The problem was found later during routine checks after the test was completed. This means the issue did not show up during the final major test that was supposed to confirm the rocket was fully ready to fly.
Engineers are trying to find out exactly where the problem is. They are checking the helium pipes that carry the gas, a control valve inside the rocket’s upper stage, and a filter that connects the ground equipment to the rocket.
Until they fix the issue, the team is using a backup system to keep the rocket’s upper stage safe, properly pressurized, and stable, so nothing gets damaged.
This problem is similar to one that happened during the Artemis 1 mission in 2022, when a faulty helium check valve in the same type of upper stage forced NASA to move the rocket back to the Vehicle Assembly Building (VAB). However, in that case, the issue was found during the wet dress rehearsal test itself.
No matter where the current problem started, the rocket has to be moved back to the Vehicle Assembly Building (VAB) before engineers can properly fix it. This 525-foot-tall building, one of the largest buildings in the world by volume, is the only place ever used to put together a rocket that carried humans to another world. Inside the VAB, engineers have large cranes and a controlled indoor environment, which help them safely repair and check the rocket’s upper stage.
To reach the building, the rocket will travel about 6.8 kilometres along a special road at a very slow speed of around 1.6 kilometres per hour, carried by NASA’s huge moving platform called the crawler. The crawler alone weighs about 3,000 tons (without load) and can carry up to 8,100 tons. It uses nearly 165 gallons (624.5 lts) of diesel for every mile it moves, showing how massive and powerful it is.
The launch pad platforms that were set up on February 20 for launch preparations had to be removed first. This was done to protect them from expected strong winds and also to clear the way in case the rocket needed to be moved back. Now that this work is finished, the path is clear for the rocket to return to the Vehicle Assembly Building (VAB) as early as February 24.
Because of the Moon’s flight path requirements, Artemis 2 can launch only during a short window of a few days, and this chance comes about once every four weeks. Due to the helium leak and the repair work needed, the mission will now miss the March 6–11 launch window.
As reported by astronomy.com , the next launch window is from April 1 to April 6, and NASA is now aiming for this period. However, if engineers are unable to fix the problem and prepare the rocket in time, the mission could be delayed even further. The agency will also hold a media briefing in the coming days to give more details.
The Artemis 2 crew — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch (NASA), and Mission Specialist Jeremy Hansen (Canadian Space Agency) — were released from quarantine and returned to Houston once again.
The crew had first started their usual 14-day pre-launch quarantine on January 23, but they were released early February after the launch was postponed from its planned February window to March.
