Para João Barros, presidente da AI², um dos grandes desafios para a próxima década em Portugal é fazer evoluir o “sistema científico e tecnológico altamente fragmentado” para um ecossistema em que “todos os componentes estão profundamente interligados". A ideia é um dos objetivos da nova agência que funde a ANI e a FCT.

A private seller in Littleton, Colorado has listed a brand-new 2027 Rivian R2 Performance on Cars.com for $79,900 — roughly $20,000 over what Rivian charges for the same vehicle.
The listing went up July 1, just weeks after Rivian started delivering the R2 to its first customers, and it comes with the kind of cover story flippers tend to lean on.
This week in stories we’re covering at The Debrief… Japan’s Hayabusa2 spacecraft just completed its flyby of the mysterious asteroid Torifune over the weekend, in a celestial rendezvous that nearly coincided with the Chinese Tianwen-2 mission’s successful capturing of new images of Earth’s “quasi-moon”. Equally intriguing are the unusual “polygon” structures NASA’s Curiosity rover just spotted and photographed on the Martian surface; what are they, and what caused them? And finally, bringing things back down to Earth a bit, scientists have revealed new details about an odd “reversal” that occurred deep within the Earth’s molten core, and what new findings suggest that could mean.
In addition to these stories, here’s a look at more of the stories we’re following right now at The Debrief…
The Chinese Tianwen-2 mission has captured the first imagery of a space object that some astronomers are calling Earth’s “quasi-moon.”
The object was captured in images released by the China National Space Administration (CNSA), after its Tianwen-2 spacecraft reached the tiny asteroid 469219 Kamoʻoalewa. Initially discovered in 2016, the asteroid became the target of a sample return mission launched by China on 28 May 2025.
Officially the CNSA’s second mission under its Planetary Exploration of China Program, Tianwen-2 aims to return close to 100 grams of samples from the surface of the small object.
Quasi-moons are the name astronomers have for small, very distant objects that do not impact our planet’s tides or possess other characteristics associated with our primary moon.
These objects are nonetheless considered moon-like because they remain in our celestial neighborhood for extended periods, providing unique opportunities for studying near-Earth objects (NEOs) like asteroids, and the impact things like solar radiation and gravity have on them.
Although Kamoʻoalewa (also known as asteroid 2016 HO3) is the most well-known of Earth’s quasi-moons, it is one of seven that are currently known to astronomers. Kamoʻoalewa’s orbit is technically also around the Sun, rather than Earth, although its synchronized path keeps it locked closely to Earth’s orbit, thereby justifying its recognition as a “quasi-satellite.”
The object’s size and distance make it an ideal target for studying NEOs, and China leaped at the opportunity with the CNSA’s Tianwen-2 mission.
The Tianwen-2 spacecraft is currently nearing 20 kilometers from the 130 to 330-foot space rock, according to a statement CNSA released on Monday.
Along with a mission update, the CNSA also released new images, which are the first to officially document the object’s appearance. According to current mission timelines, Tianwen-2 will remain in the vicinity of 469219 Kamoʻoalewa until next April, and by sometime in November 2027, its return capsule is expected to reach Earth.
After its study of 469219 Kamoʻoalewa, Tianwen-2 will then make its way with the aid of a gravity assist in the direction of the comet 311P/PANSTARRS, arriving in its vicinity by January 2035.
“Going forward, the probe will gradually conduct more detailed scientific explorations to obtain information on the asteroid’s shape, material composition, and internal structure,” read the CNSA’s statement on Monday.
The agency said its ongoing collection of information will help to provide “support for preparations for sampling,” and the spacecraft will spend the next several months conducting reconnaissance of the asteroid before its sample collection begins, which will combine high-speed maneuvers with the deployment of a specialized robotic arm.
Following their collection, the samples will be delivered to a recovery site in the Gobi Desert after dropping into Earth’s atmosphere in November 2027.

Rivian has commenced an underwritten public offering of 75 million shares of common stock, a raise worth roughly $1.5 billion based on the stock’s recent price.
The capital raise lands just days after Rivian’s stock rallied on stronger-than-expected Q2 delivery results and a raised full-year outlook.
The Hayabusa2 spacecraft completed its flyby of the asteroid Torifune over the weekend, according to a statement issued by Japan’s space agency.
The intrepid Japan Aerospace Exploration Agency (JAXA) probe’s visit marks one of the closest approaches a spacecraft has ever made to a distant asteroid, and follows Hayabusa2’s successful 2020 mission to return samples from the asteroid Ryugu.
Information obtained during the flyby, which occurred on Sunday, may help to provide new insights into both the composition of these ancient space rocks drifting through our solar system, as well as how to defend our planet if one large enough to pose a significant risk were ever to make its way here.
At approximately 6:30 p.m. Japan Standard Time on Sunday, Hayabusa2 passed the asteroid while traveling at speeds approaching 5 kilometers per second.
The recent achievement comprises part of the probe’s extended mission, which will include a future visit to the small asteroid 1998 KY26, which is expected to occur in 2031.
Over the weekend, the spacecraft’s flyby of Torifune helped to showcase Hayabusa2’s orbital guidance systems, as well as its ability to monitor asteroids and collect data to aid in the protection against potentially dangerous near-Earth objects (NEOs) before they become a threat, the Japanese Times reported.
Fortunately, asteroids with life-threatening potential only reach the Earth every few hundred years on average, and none currently being monitored by space agencies around the world are believed to represent any imminent threat.
One of the most difficult aspects of flybys like the one on Sunday involves the speeds at which spacecraft are moving, which can make avoiding a collision with the asteroid complicated. This is partly because of their dark coloration, which prevents visual confirmation of their location until just days before the flyby occurs, leaving only a small window for planning and preparation.
In a statement, Japan’s space agency said that these difficulties mean “that the flyby operation is similar to orbit-inducing technologies used to collide a spacecraft with an asteroid.”
If such technologies were to be used for planetary defense in the future, such a direct collision would be the goal, thereby aiming to set any potentially dangerous NEOs off course and keep Earth out of their line of fire.
In addition to the probe’s 2031 visit to 1998 KY26, JAXA officials say that additional opportunities for future reconnaissance will be likely, and that Sunday’s flyby served as an important dress rehearsal in that regard.
Additionally, data obtained from the flyby will be useful in helping JAXA officials and other space agencies around the world to know what to expect should a planetary defense effort become a requirement at any time in the future.
Once Hayabusa2 reaches 1998 KY26 in the early 2030s, it will mark the first time a spacecraft has engaged in close-range explorations of such an asteroid, which is currently estimated to be approximately 30 meters in diameter.
Additional details about the Hayabusa2 mission can be found at JAXA’s website.
