NASA’s X-59 Quiet SuperSonic Technology X-plane is designed to fly faster than the speed of sound without producing sonic booms – those loud, startling noises which can be disruptive to humans and animals. Currently, commercial aircraft aren’t allowed to fly faster than the speed of sound over land because of the objectionable sonic booms they cause fo...

A cataclysmic cosmic collision takes center stage in this image taken with the NASA/ESA Hubble Space Telescope. The image features the interacting galaxy pair IC 1623, which lies around 275 million light-years away in the constellation Cetus (the Whale). The two galaxies are in the final stages of merging, and astronomers expect a powerful inflow of gas to i...
In this June 2021 image, our Sun’s glint beams off the Indian Ocean as the International Space Station orbited about 270 miles above the Earth near western Australia. The station orbits the Earth about every 90 minutes at a speed of more than 17,000 miles per hour. Image Credit: NASA 在这张2021年6月拍摄的照片中，国际空间站在靠近澳大利亚西部的地球上空约270英里处环绕运行，太阳的光芒在印度洋上方闪耀。空间站每90分...

In a series of flights between June 1-6, 2021, Stratodynamics Inc. launched its HiDRON stratospheric glider from a high-altitude balloon at Spaceport America in New Mexico. HiDRON carried technology supported by NASA’s Flight Opportunities program for the first time. The uncrewed HiDRON stratospheric glider from Stratodynamics is designed to release from a s...
When NASA’s Orion spacecraft launches aboard the powerful Space Launch System rocket for the spacecraft’s first mission around the Moon later this year, a suited manikin will be aboard outfitted with sensors to provide data on what crew members may experience in flight. As part of the uncrewed Artemis I flight test, NASA is seeking to learn how best to prote...
Teams with NASA’s Exploration Ground Systems and contractor Jacobs lower the Space Launch System (SLS) core stage – the largest part of the rocket – onto the mobile launcher, in between the twin solid rocket boosters, inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on June 12, 2021. The 188,000-pound core stage, w...
