Hope mission will gather sorely needed data on the Martian atmosphere, boost Emirati space science.
Curiosity Mars Rover’s Summer Road Trip Has Begun. The footage in this video was taken between February and April 2020.
NASA is about to begin building its latest spacecraft. Called “Psyche” it will explore a 140 miles/226 kilometers-wide asteroid called “16 Psyche.” Today it’s passed a major milestone.
Why is NASA going to ‘16 Psyche?’
Located in the Solar System’s main asteroid belt between Mars and Jupiter, metal-rich 16 Psyche is thought to be the exposed metallic iron, nickel and gold core of a protoplanet. Most asteroids are rocky or icy.
Quantum information scientists have introduced a new method for machine-learning classifications in quantum computing. The non-linear quantum kernels in a quantum binary classifier provide new insights for improving the accuracy of quantum machine learning, deemed able to outperform the current AI technology.
The research team led by Professor June-Koo Kevin Rhee from the School of Electrical Engineering, proposed a quantum classifier based on quantum state fidelity by using a different initial state and replacing the Hadamard classification with a swap test. Unlike the conventional approach, this method is expected to significantly enhance the classification tasks when the training dataset is small, by exploiting the quantum advantage in finding non-linear features in a large feature space.
Quantum machine learning holds promise as one of the imperative applications for quantum computing. In machine learning, one fundamental problem for a wide range of applications is classification, a task needed for recognizing patterns in labeled training data in order to assign a label to new, previously unseen data; and the kernel method has been an invaluable classification tool for identifying non-linear relationships in complex data.
On March 12th 2020 a space telescope called Swift detected a burst of radiation from halfway across the Milky Way. Within a week, the newly discovered X-ray source, named Swift J1818.0–1607, was found to be a magnetar, a rare type of slowly rotating neutron star with one of the most powerful magnetic fields in the universe.
Spinning once every 1.4 seconds, it’s the fastest spinning magnetar known, and possibly one of the youngest neutron stars in the Milky Way. It also emits radio pulses like those seen from pulsars—another type of rotating neutron star. At the time of this detection, only four other radio-pulse-emitting magnetars were known, making Swift J1818.0–1607 an extremely rare discovery.
In a recently published study led by a team of scientists from the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav), it was found that the pulses from the magnetar become significantly fainter when going from low to high radio frequencies: It has a steep radio spectrum. Its radio emission is not only steeper than the four other radio magnetars, but also steeper than ~90% of all pulsars. Additionally, they found the magnetar had become over 10 times brighter in only two weeks.
You might think you’ve seen it all via live stream. Whether it’s historic astronaut launches, the strawberry moon, or new videogame console reveals, it’s easy to take our ability to see things unfold in real-time over the internet for granted.
And yet, there’s one frontier we’ve yet to fully breached — the deep sea. Communication through water isn’t quite as simple as through air and space.
Now, a new study shows that a type of aquatic internet can send data through light beams to allow divers to instantly stream footage from under the sea to the surface.

After more than a year in a clay-rich region, Curiosity is making a mile-long journey around some deep sand so that it can explore higher up Mount Sharp.
NASA’s Curiosity Mars rover has started a road trip that will continue through the summer across roughly a mile (1.6 kilometers) of terrain. By trip’s end, the rover will be able to ascend to the next section of the 3-mile-tall Martian (5-kilometer-tall) mountain it’s been exploring since 2014, searching for conditions that may have supported ancient microbial life.
Located on the floor of Gale Crater, Mount Sharp is composed of sedimentary layers that built up over time. Each layer helps tell the story about how Mars changed from being more Earth-like — with lakes, streams and a thicker atmosphere — to the nearly-airless, freezing desert it is today.
There are about 33,400 active-duty service members in the Air Force and Space Force, sponsoring more than 55,000 family members enrolled in EFMP.
Kimberly Schuler, the Air Force’s chief for humanitarian, EFMP and expedited transfer reassignments, said in the release that consolidating those components will mean families won’t have to work through a complex process and deal with multiple organizations to get one request answered.
“Your voices were heard,” Schuler said. “Our goal is to improve the customer experience of our airmen and their families during challenging times.”
