ISRO's 101st launch, EOS-09 mission, scheduled for May 18
The Indian Space Research Organisation (ISRO) is all geared up for its 101st launch with the PSLV-C61 / EOS-09 mission, which is scheduled to be launched on May 18 at 5.59 a.m. from the Satish Dhawan Space Centre in Sriharikota.
ISRO on Thursday (May 15, 2025) said the PSLV was moved from the Payload Integration Facility to the Mobile Service Tower at the spaceport in Sriharikota for further integration.

EOS-09 is an earth observation satellite which is expected to boost India's surveillance capabilities in all-weather conditions. The satellite is equipped with C-band synthetic aperture radar enabling capturing of high-resolution images of the Earth's surface under all-weather conditions 24/7.
Chandrayaan-5/LUPEX mission
ISRO and JAXA, the space agency of Japan, jointly conducted the third face-to-face Technical Interface Meeting (TIM-3), for the Chandrayaan-5/ Lunar Polar Exploration (LUPEX) mission, in ISRO Headquarters, Bengaluru on May 13 and 14.
The meeting was attended by senior officials, project executives, and technical team members from ISRO, JAXA, and the Mitsubishi Heavy Industries (MHI), Japan.
'Following the legacy of Chandrayaan-1, Chandrayaan-2 (orbiter-based lunar exploration), Chandrayaan-3 (lander-rover based in-situ exploration) and the forthcoming Chandrayaan-4 (India's first lunar sample return mission), the Chandrayaan-5 / LUPEX mission will be the fifth mission in the Chandrayaan series of lunar missions, in collaboration with JAXA, to study the lunar volatile materials, including lunar water, in the vicinity of a Permanently Shadowed Region in the lunar south pole,' ISRO said.
The mission will be launched by JAXA onboard its H3-24L launch vehicle, carrying the ISRO-made lunar lander, which will carry the MHI, Japan-made lunar rover. ISRO, apart from developing the lunar lander, is also responsible for developing a few scientific instruments for the mission.
The scientific instruments for this mission would be contributed by ISRO, JAXA, ESA and NASA, all thematically connected with the exploration and in-situ analysis of the volatiles reserved in the lunar polar region.
The approval for the Chandrayaan-5 / LUPEX mission was received from the Government of India on March 10, 2025, in the form of financial sanction.

NASA-ISRO joint mission Axiom-4 set to launch on June 22 after multiple delays
After a series of postponements caused by technical issues, weather conditions, and safety concerns, the much-anticipated Axiom-4 mission to the International Space Station (ISS) has been rescheduled to launch on June 22, 2025, the Indian Space Research Organisation (ISRO) confirmed. The announcement followed extensive discussions between ISRO and space agencies from Poland and Hungary, whose astronauts will participate in the mission, along with India's Gaganyatri Group Captain Shubhanshu Shukla and Peggy Whitson, the former NASA astronaut who will serve as mission commander. The mission, a collaboration between Axiom Space, NASA, SpaceX, and ISRO, has faced multiple delays since its original launch target in May. Axiom-4 Mission's postponements so far The mission was initially targeted for May 29, but that date was deferred to June 8 after engineers detected issues in the electrical harness of the Crew Dragon Module . A series of subsequent delays followed, caused by weather concerns, incomplete readiness of the Falcon-9 launch vehicle, and technical faults, including an oxygen leak and anomalies in an engine actuator identified during hot fire tests.

Along with astronauts from India, Poland, and Hungary, the crew is led by Peggy Whitson, a seasoned spacefarer and former NASA astronaut. The 14-day manned mission is designed to conduct scientific experiments aboard the ISS, advancing human spaceflight and microgravity research. Safety concerns on the ISS One of the critical reasons for the latest delay involved an air leak in the Zvezda Service Module of the ISS. On June 11, ISRO and NASA flagged concerns to Roscosmos, the Russian space agency, and recommended in-situ repairs followed by low-temperature leak tests to validate the module's integrity before launch. New target and readiness conditions According to ISRO, the new date of June 22 was finalized based on the readiness of SpaceX's Falcon-9 rocket , the Dragon spacecraft, ascent weather conditions, crew health during quarantine, and the completion of necessary repairs aboard the ISS. A backup launch window is available on June 23 if needed. The Axiom-4 mission underscores the growing role of private and international cooperation in space exploration. With safety checks completed and technical hurdles addressed, the mission is now poised to lift off from NASA's Kennedy Space Center in Florida, taking another step toward a more globally connected presence in space.

Axiom-4 mission to now launch on June 22
BENGALURU: After multiple delays and rescheduling of dates, the Indian Space Research Organisation (ISRO) on Wednesday said the most anticipated Axiom-4 space mission to the International Space Station (ISS) will launch on June 22. Taking to 'X', ISRO announced the new date after Indian scientists held discussions with their counterparts from Poland and Hungary. These two countries have sent an astronaut each on the 14-day manned mission to the ISS, along with India's Gaganyatri Group Captain Shubhanshu Shukla and former NASA astronaut, who is the mission commander, Peggy Whitson. Members from Axiom Space and NASA were also part of the discussions held to address the delays and parameters. 'Based on the readiness status of the SpaceX Falcon-9 launch vehicle, the Dragon spacecraft, repairs in the Zvezda module of the space station, ascent corridor weather conditions, and the health and preparedness of the crew in quarantine, Axiom Space has informed that the next probable launch date is June 22, 2025,' ISRO said. Earlier on June 14, ISRO had announced that the mission would launch on June 19, 2025. But later the same day, it was withdrawn and ISRO said the next launch date would soon be announced. The launch was initially targeted for May 29, but deferred to June 8, 2025, because of the observations in the electrical harness in the Crew Dragon Module. The launch was then postponed to June 9 because of the delay in the preparedness of the Falcon-9 rocket. The mission was then postponed to June 10 due to inclement weather at NASA's Kennedy Space Center in Florida from where the launch was to take place. Also, during inspections and hot fire tests that were conducted on June 8, the team had observed oxygen leak in the engine bay, besides anomalies in one of the engine actuators. The launch was then rescheduled to June 11, anticipating the issues to be addressed. On June 11, NASA and ISRO flagged their concerns to Russian space agency Roscosmos to evaluate the new pressure signature in the Zvezda Service Module on the ISS due to the air leak. ISRO had recommended to Axiom Space, NASA and SpaceX to carry out in-situ repairs and conduct a low temperature leak test to validate the performance of system.
