"When a young killdeer hides in the grass, it is almost impossible to find them they are so well camouflaged. If you wait long enough, they will give themselves away, like this young killdeer checking to see if the coast is clear."

We are one small step closer to returning to the Moon. A new chapter in human exploration began yesterday when NASA's Artemis II launched aboard the Space Launch System (SLS) from Kennedy Space Center. Carrying four astronauts, the Orion spacecraft's planned lunar flyby will be the first in over half a century. This historic test flight, echoing the legacy of Apollo while pushing beyond it, will carry its crew farther from Earth than any humans since 1972, looping around the Moon before returning home. During the approximately ten-day journey, Orion's systems--from life support to navigation--will be tested in deep space, while astronauts observe the lunar surface, including shadowed regions of the far side rarely seen with such perspective. After looping around the Moon, the astronauts will return to Earth, ending their journey with a Pacific Ocean splashdown.

             A Wise Old Owl

A wise old owl lived in an oak,
The more he saw the less he spoke,
The less he spoke the more he heard,
Why can’t we all be like that bird?

NASA Astronomy Picture of the Day:

What unexpected things do you see when you look up at the night sky? Today’s image resembles an abstract painting, with large swaths of color strewn across a cosmic canvas seemingly without design. Despite the image's abstract nature, the human mind finds patterns, identifying a large claw reaching up towards a floating bubble. Embedded within these seemingly random structures are the physical laws that govern how light and matter interact. The Claw (Sh2-157) and Bubble (NGC 7635) Nebulae glow colors that are mapped to the yellow and blue shown, indicating the presence of hydrogen and oxygen ionized by the intense light emitted from stars several times the mass of the Sun. This image depicts both the chaos and structure of astronomical processes, showing that a common thread between art and science is to look for the unexpected.

Basilica of Santa Francesca, Rome, Italy. A church at the site was known by the tenth century. It was named Santa Maria Nova ("New St Mary"), to distinguish it from the other church inside the Roman forum devoted to St Mary, Santa Maria Antiqua ("Ancient St Mary"), which had fallen into ruin by then. The relics from the ancient church were moved to this church under Pope Leo. Santa Maria Nuova was enlarged in the second half of the tenth century, and then rebuilt by Pope Honorius III in the thirteenth century, adding the campanile and the apse, as well as being decorated with a mosaic Maestà, a depiction of the Madonna enthroned accompanied by saints (as seen in the picture). Since 1352 the church has been in the care of the Olivetans. In the 16th century, the church was rededicated to Frances of Rome (Francesca Buzzi), who was canonized in 1608 and whose relics are in the crypt. The interior of the church has undergone many refurbishments.

NASA Astronomy Picture of the Day:

Titania's tortured terrain is a mix of canyons, cliffs, and craters. NASA's interplanetary robot spacecraft Voyager 2 passed the largest moon of Uranus in 1986 and took the feature picture. That the trenches of Titania resemble those on another moon of Uranus, Ariel, indicate that Titania underwent some violent surface event possibly related to water freezing and expanding in its distant past. Although Titania is Uranus's largest moon, it is only about half the radius of Triton - the largest moon of Uranus's sister planet Neptune, which itself is slightly smaller than Earth's Moon. Titania, discovered by William Herschel in 1787, is essentially a large dirty iceball that is composed of about half water-ice and half rock. There is recent speculation that radioactive heating melts some underground ice into oceans.
