A worsening air leak aboard the International Space Station briefly prompted NASA to place five astronauts on standby for a possible evacuation on June 5. The precautionary order followed a sudden increase in air loss within the Russian Zvezda service module, where two leaks were identified. Four Crew-12 members and another NASA astronaut were instructed to move into a docked SpaceX Crew Dragon spacecraft before the alert was lifted roughly two hours later after consultations with Roscosmos. One leak was sealed, while repairs continued on the second. Officials stressed there was no immediate threat to crew safety, and normal station operations subsequently resumed. (PC: News18)

Astronauts aboard the International Space Station were instructed by NASA to shelter in their spacecraft and prepare for a possible evacuation after a worsening air leak was detected in the Russian-built Zvezda service module. The leak, located in the module’s transfer tunnel, has been a long-standing concern, but recent signs of deterioration prompted Russian space agency Roscosmos to begin extensive repair operations. As a precaution, members of NASA’s SpaceX Crew-12 mission, along with other station residents, were placed on alert and told to be ready for an emergency departure if required. NASA emphasized that the move was made out of caution while engineers continue monitoring the situation. (PC: The Guardian)

Blue Origin’s New Glenn rocket exploded during a hotfire static test at Launch Complex-36 in Cape Canaveral, Florida, sending massive flames and smoke across the launch pad. The incident occurred while engineers were testing propulsion systems ahead of a planned mission carrying 48 Amazon Leo broadband satellites into low-Earth orbit. Blue Origin confirmed an “anomaly” during the test and said all personnel were safely accounted for. Founder Jeff Bezos called it a “very rough day” and vowed the company would rebuild and resume operations. NASA said it is assessing possible impacts on Artemis and Moon Base programmes. Industry experts warned the blast and possible launch pad damage could significantly delay Blue Origin’s lunar mission ambitions.

Red Balloon Aerospace successfully launched India’s first indigenous private super-pressure balloon carrying commercial payloads, marking a major milestone in the country’s near-space ambitions. The company’s VISTA platform rose nearly 25 kilometres above Earth during Mission SANA from Vijayawada, operating within the stratosphere between aircraft and satellites. Founded in 2025, the startup achieved commercial operational flight within eight months. The mission carried payloads from seven national and international partners, including biological experiments, propulsion systems and earth observation technologies. CEO C V S Kiran said the achievement places India among only five nations with indigenous stratospheric hydrogen balloon capability alongside the US, France, Japan and China.

Manipuri astrophysicist Ronaldo Laishram has led an international team in discovering a massive 12.6-billion-year-old protocluster, named the “Loktak Protocluster” after Manipur’s famous Loktak Lake. Published in The Astrophysical Journal Letters, the discovery sheds light on how galaxies evolved in the early Universe when it was only 1.2 billion years old. Researchers used observations from the Subaru Telescope and the James Webb Space Telescope to study the structure, which contains four connected galaxy concentrations. Laishram said the name honours Manipur’s identity and connects his home state to the wider story of the Universe. (PC: X) 

NASA has outlined a multi-phase, approximately $20 billion roadmap under the Artemis program to establish a permanent human presence on the Moon. The plan includes up to 25 robotic missions and 21 lunar landings by 2029, focusing on the Moon’s south pole. Key technologies include autonomous Lunar Terrain Vehicles, MoonFall hopping drones and robotic cargo systems. Contracts have been awarded to Blue Origin, Astrolab, Lunar Oupost and Firefly Aerospace to support lunar transport and exploration infrastructure. NASA aims to develop habitats, power systems and communication networks, eventually enabling continuous lunar operations and supporting future missions to Mars.

The Pentagon has released “never-before-seen” declassified files on UFOs, officially referred to as Unidentified Anomalous Phenomena (UAP), following a directive from US President Donald Trump. The files include decades of investigations, eyewitness accounts, military memos, infrared images, and astronaut reports from missions like Apollo 12 Moon Landing and Apollo 17 Moon Landing. Recent reports mention unidentified objects observed in Iraq, Syria, the UAE, and Greece. The Defense Department clarified that many descriptions are subjective and not proof of extraterrestrial activity. Barack Obama and Jared Isaacman also commented on growing public interest and transparency regarding unexplained aerial phenomena.

Scientists from the Indian Space Research Organisation have confirmed that strong solar activity speeds up the fall of old satellites and space debris back towards Earth. Researchers at the Vikram Sarabhai Space Centre tracked 17 pieces of orbital debris over 34 years and found that rising solar activity increases atmospheric drag in space. This causes debris to lose altitude faster and eventually re-enter Earth’s atmosphere. The study observed the pattern across three solar cycles between 1986 and 2024. Scientists said the findings could help space agencies plan safer missions and better manage growing concerns over space junk in Earth’s orbit. (PC: NDTV)

India’s Drishti Satellite, developed by GalaxEye, marks a breakthrough in Earth observation by combining multispectral imaging and synthetic aperture radar in one platform. Launched aboard Falcon 9 by SpaceX, it can capture high-resolution images through clouds and darkness, addressing limitations faced in tropical regions like India. With 1.5-metre resolution and plans for a larger constellation, Drishti enhances applications in defence, agriculture and disaster management. Experts say such sovereign capability reduces reliance on foreign data, a gap highlighted during recent conflicts, strengthening India’s strategic autonomy and surveillance capabilities in a geopolitically sensitive region.

A heartwarming video shows Christina Koch reuniting with her dog Sadie after returning from the Artemis II mission. Shared on Instagram, the clip captures Sadie’s joyful reaction of barking, wagging her tail, and running excitedly as Koch enters her home. Koch humorously noted she might have been the happier one, crediting Sadie as an emotional support companion. Koch and fellow astronauts traveled 694,481 miles, setting a new record for the farthest human journey from Earth, surpassing Apollo 13. After 10 days in space, the crew safely splashed down in the Pacific, with mission data expected to support future lunar exploration.
