Size comparison of a human and Atrociraptor
Size comparison of a human and Atrociraptor

Atrociraptor is a genus of dromaeosaurid dinosaur that lived during the Late Cretaceous in what is now Alberta, Canada. The first specimen was discovered in 1995 by the fossil collector Wayne Marshall in the Horseshoe Canyon Formation. In 2004, this became the holotype of the new genus and species Atrociraptor marshalli; the generic name is Latin for 'savage robber'. It is estimated to have measured 1.8 to 2 m (5.9 to 6.6 ft) in length and weighed 15 kg (33 lb). It would have had a large sickle-claw on the second toe and pennaceous feathers. Atrociraptor has a deeper face and more strongly backwards-inclined teeth than its contemporary relatives. It is thought to have been specialised for attacking larger prey due to its deep snout. Studies suggest dromaeosaurids used their sickle-claws to restrain prey while dismembering them with the mouth. Atrociraptor dates from around 72.2 to 71.5 million years ago; it survived for more than 2 million years and across a wide geographic area. (Full article...)

Artemis I

Artemis I was an uncrewed Moon-orbiting mission that was launched on November 16, 2022. It was the first major spaceflight of NASA's Artemis program and marked the agency's return to lunar exploration since the Apollo program after five decades. It was the first flight test of the Orion spacecraft and the Space Launch System (SLS) rocket, and the mission's main objective was to test the Orion spacecraft in preparation for future Artemis missions. Artemis I was launched from Launch Complex 39B at the Kennedy Space Center. After reaching orbit, the upper stage separated and performed a trans-lunar injection before releasing Orion and ten CubeSat satellites. Orion completed one flyby of the Moon on November 21 and completed a second flyby on December 5. This picture shows Artemis I launching from Launch Complex 39B.
