Russia launches rescue ship to space station after leaks

Published

on

Russia launched a rescue ship on Friday for two cosmonauts and a NASA astronaut whose original ride home sprang a dangerous leak while parked at the International Space Station.

The new, empty Soyuz capsule should arrive at the orbiting lab on Sunday, The Associated Press reported.

The capsule leak in December was blamed on a micrometeorite that punctured an external radiator, draining it of coolant. The same thing appeared to happen again earlier this month, this time on a docked Russian cargo ship. Camera views showed a small hole in each spacecraft.

The Russian Space Agency delayed the launch of the replacement Soyuz, looking for any manufacturing defects. No issues were found, and the agency proceeded with Friday’s predawn launch from Kazakhstan of the capsule with bundles of supplies strapped into the three seats.

Given the urgent need for this capsule, two top NASA officials traveled from the U.S. to observe the launch in person. To everyone’s relief, the capsule safely reached orbit nine minutes after liftoff — “a perfect ride to orbit,” NASA Mission Control’s Rob Navias reported from Houston.

Officials had determined it was too risky to bring NASA’s Frank Rubio and Russia’s Sergey Prokopyev and Dmitri Petelin back in their damaged Soyuz next month as originally planned. With no coolant, the cabin temperature would spike during the trip back to Earth, potentially damaging computers and other equipment, and exposing the suited-up crew to excessive heat.

Until the new Soyuz pulls up, emergency plans call for Rubio to switch to a SpaceX crew capsule that’s docked at the space station. Prokopyev and Petelin remain assigned to their damaged Soyuz in the unlikely need for a fast getaway. Having one less person on board would keep the temperature down to a hopefully manageable level, Russian engineers concluded.

The damaged Soyuz will return to Earth with no one aboard by the end of March, so engineers can examine it.

The three men launched in this Soyuz last September on what should have been a six-month mission. They’ll now stay in space for a full year, until a new capsule is ready for their crew replacements for liftoff in September. It was their Soyuz that just launched with no one on board.

“The Russians are continuing to take a really close look” at both spacecraft leaks, NASA’s deputy space station program manager Dana Weigel told reporters earlier this week. “They’re looking at everything … to try to understand that.”

NASA has a fresh crew of four launching atop a SpaceX rocket early Monday morning from Florida’s Kennedy Space Center. SpaceX’s William Gerstenmaier said the four astronauts returning to Earth in a few weeks already have inspected the Dragon capsule that will carry them home and “it all checked out fine.”

Meta turns off Instagram’s private messaging encryption worldwide

Meta said the decision was based on low user adoption, though critics argue optional privacy tools often see limited use because users must manually activate them.

Published

Instagram has disabled its end-to-end encrypted (E2EE) direct messaging feature worldwide, marking a major reversal by parent company Meta on its previous commitment to stronger user privacy protections.

The move means Instagram users can no longer send ultra-private direct messages protected by E2EE — a security system that allows only the sender and recipient to read messages. Without the feature, Instagram can technically access the content of direct messages, including photos, videos and voice notes.

Meta had previously promoted encryption as “the future is private.” In 2019, CEO Mark Zuckerberg pledged to expand the technology across the company’s platforms.

Facebook Messenger adopted E2EE in 2023, while Instagram introduced it as an optional feature with plans to make it standard.

However, Meta has now abandoned the wider Instagram rollout and updated the app’s terms in March to confirm encrypted messaging would no longer be supported after 8 May 2026.

Meta said the decision was based on low user adoption, though critics argue optional privacy tools often see limited use because users must manually activate them.

The move has divided opinion. Child protection groups, including the NSPCC, welcomed the change, saying encryption can make it harder to detect child grooming and abuse online.

Privacy advocates criticised the decision. Maya Thomas of Big Brother Watch warned the move weakens online privacy protections and could increase pressure on other social media companies to scale back encryption.

End-to-end encryption remains standard on platforms including WhatsApp, Signal, Apple’s iMessage and Google Messages, while other platforms continue to take mixed approaches to private messaging.

James Webb Telescope captures clearest-ever view of exoplanet’s surface

Published

on

Astronomers using NASA’s James Webb Space Telescope have obtained the clearest view yet of the surface of a rocky exoplanet, revealing a scorched, atmosphere-free world that scientists say resembles a giant version of Mercury.

The planet, known as LHS 3844 b and nicknamed “Kua’kua,” appears to be a barren, uninhabitable world with extreme temperature swings and no detectable atmosphere, according to a study published this week in Nature Astronomy.

Researchers said the planet’s surface is likely covered in dark volcanic rock and ancient regolith — loose rocky debris formed over billions of years from relentless bombardment by radiation and micrometeorite impacts.

“This planet is not a nice place,” said astronomer Laura Kreidberg, senior author of the study. “It’s a hellish, barren rock — much more similar to Mercury than Earth.”

Located about 49 light-years away, LHS 3844 b orbits a small red dwarf star and completes a full orbit every 11 hours. The planet is tidally locked, meaning one side permanently faces its star while the other remains in darkness — similar to how the Moon always shows the same face to Earth.

Scientists found the planet’s dayside reaches roughly 1,340 degrees Fahrenheit (725 degrees Celsius), while the nightside showed almost no detectable heat.

Using Webb’s infrared instruments, researchers were able to directly analyze light coming from the planet’s surface — a major breakthrough for exoplanet science.

“Different rocks have different spectral fingerprints,” said lead author Sebastian Zieba. “Dark volcanic rocks like basalt matched our observations much better than brighter rocks like granite.”

The findings mark a new phase in exoplanet research, shifting beyond atmospheric studies toward direct analysis of alien geology and surface composition.

Since becoming operational in 2022, the Webb telescope has transformed scientists’ understanding of planets beyond the solar system, helping identify atmospheric chemistry, weather patterns and now even the nature of distant planetary surfaces.

Researchers said the absence of an atmosphere on LHS 3844 b means there is little protection from stellar radiation and virtually no possibility of liquid water — a key ingredient for life.

“So overall, this is almost certainly not a habitable world,” Zieba said.

Afghanistan has launched its first-ever 5G telecommunications trial in Kabul, marking a major milestone in efforts to modernise the country’s digital infrastructure.

The announcement followed a meeting between Hamdullah Nomani, Minister of Communications and Information Technology, and Aliullah Sarwari, head of the Afghan Wireless Communication Company (AWCC), where discussions focused on expanding telecom coverage, improving service quality, and extending connectivity to remote regions.

According to ministry spokesperson Enayatullah Alokozai, AWCC has upgraded 74 telecom antennas in Kabul to 5G on a trial basis. Once technical preparations and testing are completed, the company plans to extend 5G services to other provinces.

Officials also reported steady progress on broader infrastructure development. Eight telecom sites approved during previous official visits to northern and southeastern provinces have been completed, one is nearing completion, and construction continues on two additional sites expected to become operational soon.

In parallel, the Afghanistan Telecom Regulatory Authority (ATRA) has approved eight more telecom sites under the Telecom Development Fund (TDF), with implementation scheduled in the coming months.

Sarwari noted that since the beginning of 2026, AWCC has built and activated 46 telecom sites using its development budget, while work continues on a further 186 sites nationwide.

He also thanked the Ministry of Communications and Information Technology for its ongoing support in facilitating sector growth and improving service delivery.

Nomani meanwhile emphasised that telecommunications play a crucial role in national development and said the government remains committed to working closely with operators to expand modern, high-quality digital services.

Officials added that cooperation between the ministry, regulators, and telecom companies will continue across all operational and regulatory areas to strengthen Afghanistan’s communications network.
