In August 2026, a series of powerful winter storms transformed parts of northern Chile’s Atacama Desert, covering the famously dry landscape in an unusual layer of snow. Snow is not unheard of in the Atacama. Significant falls occurred in 2025 and, before that, in 2011. But one of the August 2026 storms stood out because [...]Construir uma base na Lua é muito mais do que levar astronautas até lá. A NASA procura soluções para produzir energia, extrair oxigénio do regolito lunar e fabricar no próprio local materiais que possam ser usados na construção e nas operações.

Puerto Rico went from no drought to widespread extreme drought in just months as rainfall collapsed and water shortages spread. Puerto Rico usually enters its wet season in May. In 2026, however, the expected rains largely failed to arrive through late August, leaving much of the U.S. territory in drought. The prolonged dry spell has [...]The European Space Agency is moving "full steam ahead" with development of a robotic mission to Venus after NASA officials determined they were unlikely to fulfill a commitment to provide a US-built radar instrument for the spacecraft, the mission's project scientist said.
The European orbiter, named Envision, will map the Venusian surface at 10 times higher resolution than the last radar mission sent to Venus by NASA in the 1990s. The planet is enshrouded in a blanket of thick clouds of sulfuric acid, rendering its mysterious surface unseen by optical cameras in orbit. Radar is the most effective way to penetrate the clouds of Venus to reveal the terrain below, and scientists will use Envision to look for signs of active volcanism.
NASA and ESA signed a memorandum of understanding in 2024 outlining their partnership on Envision. NASA agreed to supply a US-made synthetic aperture radar instrument, Envision's primary means of mapping the surface of Venus, along with providing tracking and communications support through NASA's Deep Space Network. In exchange, ESA would include US researchers on Envision's science team. Europe would build the Envision spacecraft and the rest of its science instruments and provide the launch on an Ariane 6 rocket.

The commander and pilot of NASA's Artemis II mission have gained a new distinction five months after splashing down from the Moon: They're not fully retiring from the space agency.
Reid Wiseman and Victor Glover are the first astronauts to join NASA's emeritus program, enabling them to continue to support the work being done at Johnson Space Center in Houston. They will remain available to train and mentor the current workforce while still being able to pursue employment and opportunities outside of NASA.
"I have asked NASA ... to not use the term 'retire' as much, but technically emeritus is a retirement program," Glover told collectSPACE.com on Wednesday. "It's something we have typically done for scientists when they have groundbreaking research, and they want to go back to academia to teach or to research and publish."

A giant 29-square-mile iceberg broke from Greenland’s Petermann Glacier and survived a collision with Joe Island that might have shattered a more fragile berg. Summer is the busiest time of year for iceberg activity in Greenland’s glacier-fed fjords, and 2026 brought another dramatic example. In August, a huge iceberg separated from Petermann Glacier on Greenland’s [...]New Mexico’s largest reservoir plunged to just 1.4 percent capacity in July 2026, revealing the dramatic impact of prolonged drought and record early snowmelt. NASA is using satellite data to help water managers understand the shrinking supply and prepare for future shortages. When astronaut John Glenn remarked on the landscape below him while orbiting Earth [...]NASA’s Neil Gehrels Swift Observatory is back to business after months flying in a stripped-down mode while it waited for a rescue mission that ultimately failed. On August 26, the agency switched Swift’s Ultraviolet/Optical Telescope and X-ray Telescope back on. A third instrument, the Burst Alert Telescope (BAT), remains offline while a team works to return it to data collection in the coming weeks.
Earlier this month, Link, the Katalyst Space spacecraft that was originally set to rescue Swift conducted in-space tests and maneuvers to test its capabilities for future, and hopefully successful, missions.
“Katalyst continues to demonstrate as many of LINK’s capabilities in space as possible, to collect data to inform future spacecraft servicing technology and operations,” per a statement from NASA on September 4.
It also snapped a few photos of Swift from about 9 miles away. “We got so close, but so far,” Katalyst’s CEOGhonhee Lee told the Associated Press.
The shutdowns, put in place in February, were part of an effort to give Swift more time. The observatory has studied powerful explosions called gamma-ray bursts since 2004. Unlike other low-orbit satellites, Swift does not have a propulsion system that can counteract the pull of the Earth orbit. At the same time, increased solar activity has caused the Earth’s upper atmosphere to expand, increasing the atmospheric drag on Swift faster than anticipated.
That force would eventually cause the satellite to fall into the Earth’s atmosphere and burn up. So, in 2025, NASA enlisted Katalyst Space to build Link to capture Swift and lift it into higher orbit. However, those plans were scrapped on August 19 after Link went into an uncontrollable spin.
With science operations now resumed, NASA believes Swift will reach an altitude 185 miles (300 kilometers) for the next one to two months. After that threshold, “operating the telescope becomes difficult, and the spacecraft’s rate of descent quickly increases,” the agency explained in a statement.
At that point, the satellite’s 22-year observation of the cosmos will finally come to an end. It’s expected to fall back to Earth sometime between October and late December. One thing is for certain, Swift served us well.
