NASA formally retires Mars InSight lander after 4-year mission
NASA has formally retired its Mars InSight lander, the first robotic probe specially designed to study the deep interior of a distant world, four years after it arrived on the surface of the red planet, the US space agency announced on Wednesday.
Mission controllers at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles determined the mission was over when two consecutive attempts to re-establish radio contact with the lander failed, a sign that InSight’s solar-powered batteries had run out of energy, Reuters reported.
NASA predicted in late October that the spacecraft would reach the end of its operational life in a matter of weeks due to increasingly heavy accumulations of dust on its solar panels, depleting the ability of its batteries to recharge.
JPL engineers will continue to listen for a signal from the lander, just in case, but hearing from InSight again is unlikely, NASA said. The three-legged stationary probe last communicated with Earth on Dec. 15.
According to Reuters InSight landed on Mars in late November 2018 with instruments designed to detect planetary seismic rumblings never before measured anywhere but Earth, and its original two-year mission was later extended to four.
From its perch in a vast and relatively flat plain called Elysium Planitia just north of the planet’s equator, the lander has helped scientists gain new understanding of Mars’ internal structure.
Researchers said InSight’s data revealed the thickness of the planet’s outer crust, the size and density of its inner core and the structure of the mantle that lies in between.
One of InSight’s chief accomplishments was establishing that the red planet is, indeed, seismically active, recording more than 1,300 marsquakes. It also measured seismic waves generated by meteorite impacts, read the report.
“The seismic data alone from this discovery program mission offers tremendous insights not just into Mars but other rocky bodies, including Earth,” said Thomas Zurbuchen, associate administrator of NASA’s science mission directorate.
One such impact a year ago was found to have gouged boulder-sized chunks of water ice surprisingly close to Mars’ equator.
Even as InSight retires, a more recent robotic visitor to the red planet, NASA’s science rover Perseverance, continues to prepare a collection of Martian mineral samples for future analysis on Earth.
This week, Perseverance deposited the first of 10 sample tubes it was directed to leave at a surface collection site on Mars as a backup cache, in case the primary supply stored in the rover’s belly cannot for some reason be transferred as planned to a retrieval spacecraft in the future, NASA said.

Ethiopian volcano erupts for first time in nearly 12,000 years
Ash from the eruption drifted across the region, spreading over Yemen, Oman, India, and parts of Pakistan.
The Hayli Gubbi volcano in Ethiopia’s Afar region has erupted for the first time in almost 12,000 years, sending massive ash plumes soaring up to 14 kilometres into the atmosphere, according to the Toulouse Volcanic Ash Advisory Centre.
The eruption began on Sunday and lasted several hours. Hayli Gubbi, located around 800 kilometres northeast of Addis Ababa near the Eritrean border, sits within the geologically active Rift Valley, where two major tectonic plates meet. The volcano rises roughly 500 metres above the surrounding landscape.
Ash from the eruption drifted across the region, spreading over Yemen, Oman, India, and parts of Pakistan. Satellite imagery and social-media videos captured a towering column of white smoke billowing into the sky.
The Smithsonian Institution’s Global Volcanism Program notes that Hayli Gubbi has no recorded eruptions during the Holocene, the period dating back about 12,000 years to the end of the last Ice Age.
Volcanologist Simon Carn of Michigan Technological University also confirmed on Bluesky that the volcano had “no record of Holocene eruptions.”

Cloudflare outage easing after millions of internet users affected
A global outage at web-infrastructure firm Cloudflare began to ease on Tuesday afternoon after preventing people from accessing major internet platforms, including X and ChatGPT.
Cloudflare, whose network handles around a fifth of web traffic, said it started to investigate the internal service degradation around 6:40 a.m. ET. It has deployed a fix but some customers might still be impacted as it recovers service.
The incident marked the latest hit to major online services. An outage of Amazon’s cloud service last month caused global turmoil as thousands of popular websites and apps, including Snapchat, were inaccessible due to the disruption.
Cloudflare – whose shares were down about 5% in premarket trading – runs one of the world’s largest networks that helps websites and apps load faster and stay online by protecting them from traffic surges and cyberattacks.
The latest outage prevented users from accessing platforms such as Canva, X, and ChatGPT, prompting users to log outage reports with Downdetector.
Downdetector tracks outages by collating status reports from a number of sources. “We saw a spike in unusual traffic to one of Cloudflare’s services beginning at 11:20 UTC. That caused some traffic passing through Cloudflare’s network to experience errors,” the company said in an emailed statement.
“We are all hands on deck to make sure all traffic is served without errors.”

China sends its youngest astronaut to ‘Heavenly Palace’ space station
China’s Shenzhou-21 space rocket and its crew including the youngest member of its astronaut corps blasted off on Friday atop a Long March-2F rocket from the Jiuquan Satellite Launch Centre in northwest China, Chinese state media reported.
It was the seventh mission to the permanently inhabited Chinese space station since it was completed in 2022, Reuters reported.
Missions on China’s Shenzhou-21 spacecraft involve trios of astronauts on six-month stays in space, with veteran astronauts increasingly replaced by younger faces. First-timers Zhang Hongzhang, 39, and Wu Fei, 32 – China’s youngest astronaut to be sent to space – were picked to participate in the programme in 2020.
Commander Zhang Lu, 48, flew on the 2022 Shenzhou-15 mission.
FIRST SMALL MAMMALS ON SPACE STATION
The Shenzhou-21 astronauts will take over from the Shenzhou-20 crew who had lived and worked on board Tiangong, or “Heavenly Palace”, for more than six months. The Shenzhou-20 astronauts will return to Earth in the coming days.
The Shenzhou-21 crew were also joined by four black mice, the first small mammals to be taken to the Chinese space station. The mice will be used in experiments on reproduction in low Earth orbit.
Biannual launches have become the norm for the Shenzhou programme, which has in the past year reached new milestones with the deployment of Chinese astronauts born in the 1990s, a world-record spacewalk, and plans to train and send the first foreign astronaut, from Pakistan, to Tiangong next year.
The rapid advances have raised alarm bells in Washington, which is now racing to put a U.S. astronaut on the moon again before China does.
Both countries are also competing in nascent institution-building efforts, with the U.S.-led Artemis Accords on lunar exploration matched up against the Chinese and Russian-led International Lunar Research Station.
