After its journey from NASA’s Stennis Space Center aboard the Pegasus barge, the core stage of the Space Launch System (SLS) rocket arrived at the agency’s Kennedy Space Center on April 27, 2021. Shown against a Florida sunrise, the core stage is the final piece of Artemis hardware to arrive at the spaceport. Engineers with Exploration Ground Systems and lead contractor Jacobs will offload the core stage and move it to the center’s Vehicle Assembly Building for integration atop the mobile launcher with the completed stack of solid rocket boosters ahead of the Artemis I launch. The SLS will be the most powerful rocket in the world, producing up to 8.8 million pounds of thrust during its Artemis I launch. Artemis I will be an…

Astronauts on the International Space Station recently enjoyed a fresh supply of leafy greens, thanks in large part to the efforts of Expedition 64 crew member Michael Hopkins. NASA’s SpaceX Crew-1 mission commander took the lead on conducting four Vegetable Production System (Veggie) experiments, with the last two wrapping up after an April 13 harvest. VEG-03K and VEG-03L tested a new space crop, ‘Amara’ mustard, and a previously grown crop, ‘Extra Dwarf’ pak choi. They were grown for 64 days, the longest leafy greens have grown on station.

Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA’s Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode. This work is based on Chandra observations of the remains of a supernova called Cassiopeia A, located in our galaxy about 11,000 light-years from Earth. This is one of the youngest known supernova remnants, with an age of about 350 years. Image Credit: NASA/CXC/RIKEN/T. Sato et al.; NuSTAR: NASA/NuSTAR) 科学家们发现了一颗著名的超新星喷发出的钛碎片。这一发现是由美国宇航局的钱德拉X射线天文完成的，可能是准确指出一些巨型恒星如何爆炸的重要一步。 这项工作是基于钱德拉对仙后座A超新星残骸的观测，仙后座A位于距离地球约11000光年的银河系中。这是已知的最年轻的超新星遗迹之一，大约有350年的历史。 影像来源：NASA/CXC/RIKEN/T.
