Il telescopio spaziale James Webb sta offrendo una visione senza precedenti dell’universo primordiale grazie alla sua capacità di osservare la luce infrarossa proveniente da oggetti estremamente lontani. Tra le sue scoperte più sorprendenti figurano galassie molto luminose e apparentemente mature esistite poche centinaia di milioni di anni dopo il Big Bang. Queste osservazioni hanno acceso un intenso dibattito scientifico, poiché suggeriscono che la crescita delle prime strutture cosmiche potrebbe essere avvenuta più rapidamente del previsto. Sebbene analisi successive abbiano ridimensionato alcune delle stime iniziali, Webb continua a fornire dati che stanno portando gli astronomi a perfezionare le teorie sulla formazione delle galassie, dei buchi neri supermassicci e dell’universo delle origini.

NASA has named the astronauts who will fly the next Artemis mission, a test flight in low Earth orbit where Orion will attempt to dock with two lunar lander prototypes.

The US space agency unveiled the crew for its Artemis III mission on Tuesday during an enthusiastic event at Johnson Space Center in Houston.

For this spaceflight into low-Earth orbit, which will see the Orion spacecraft rendezvous and dock with lunar lander prototypes, NASA chose an experienced, all-male crew with military backgrounds. They were revealed inside a darkened Teague Auditorium where hundreds of friends, family members, and NASA employees cheered enthusiastically.

The four crew members are:

NASA officials have completed an investigation into an incident that caused damage to a 70-meter radio frequency antenna last year.

The incident, which occurred at the Goldstone Deep Space Communications Complex near Barstow, California, affected the space agency’s Deep Space Station 14 (DSS-14), a 70-meter radio-frequency antenna, which currently remains offline awaiting repairs and system upgrades.

Joel Montalbano, acting associate administrator for NASA’s Space Operations Mission Directorate, emphasized that the agency “takes safety and any departure from established procedures seriously,” adding that investigations into the incident at Goldstone “made clear that we must strengthen our processes. We are acting on the investigation’s findings.”

Incident at Goldstone

The damage was caused last September 16, 2025, when the antenna reportedly over-extended during rotation during tracking for NASA’s Juno mission. Stress on the antenna’s cabling and support infrastructure, as well as damage to its fire-suppression system, is expected to cost between $4.1 and $4.6 million in repairs.

Fortunately, no injuries were reported at the time of the incident, and a Mishap Investigation Board was convened to investigate the underlying causes. Following on-site inspections, interviews, and reviews of technical documentation from NASA’s three Deep Space Network facilities, the results of the investigation were included in a report submitted in April, which also made recommendations on how to prevent future incidents.

Software Issues

A primary factor behind the incident had been what the reports’ authors characterize as “software weaknesses, human error, and an undetected failure in the antenna’s hydraulic limit system,” according to a recent NASA statement.

“Investigators determined an electrical issue at the antenna the previous day caused the control system to misreport the antenna’s rotation state, an issue that went unnoticed and triggered multiple limit-stops during the Juno track,” the statement added.

Over-rotation of the antenna resulted after flooding in the antenna base was spotted by operators, following troubleshooting efforts that accidentally bypassed safeguards in the system’s hardware and software.

Investigators also determined that the antenna’s hydraulic limit system had already been rendered inoperable before the September 16 incident, following damage sustained “in an undocumented prior incident.”

Modernization for Future Missions

On June 5, Montalbano emphasized that NASA plans to follow the guidance in the review board’s report, with a focus on ensuring greater adherence to procedures to help limit the likelihood of future mishaps.

“We will update and improve procedures, rebuild core in-house capabilities, and reinforce operational discipline across the Deep Space Network,” Montalbano said.

“NASA remains focused on learning from this and modernizing systems, so DSS-14 and the broader network are ready to support our ambitious future missions,” he added.

NASA's Artemis II crew are the fastest people alive, and now they have the patch to prove it.

Mission Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen (the latter with the Canadian Space Agency) spent 10 days in early April flying by the Moon. Their journey took them farther away from Earth than any humans have gone (52,756 miles [406,771 km]) and then, on the way back on board their Orion spacecraft Integrity, they sped up to about 24,664 miles per hour (39,693 k/ph) reentering the atmosphere.

Only three other people in history have traveled faster. NASA's Apollo 10 astronauts Thomas Stafford, John Young, and Eugene Cernan set the record for the highest speed attained by a crewed vehicle relative to the Earth's surface: 24,791 mph (39,897 kph) on May 26, 1969.

After a 50-year search, astronomers have uncovered evidence that Sagittarius A* -- the 4.3-million-solar-mass black hole that resides at the center of our Milky Way Galaxy -- is blowing a hot cosmic wind into its surroundings, carving out a giant cavity near the Galaxy’s heart.
