Astronaut Bruce McCandless II approaches his maximum distance from the Earth-orbiting Space Shuttle Challenger in this 70mm photo from Feb. 7, 1984. While testing out the nitrogen-propelled, hand-controlled back-pack device called the manned maneuvering unit (MMU) for the first time, McCandless’s fellow crewmembers aboard the reusable vehicle photographed him. The MMU allowed crews to move outside of the cargo bay and perform activities away from the safety of the spacecraft. “It may have been one small step for Neil,” he proclaimed, “but it’s a heck of a big leap for me.”

      NASA Runs X-59 Engine with Maximum Afterburner for First Time

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s X-59 quiet supersonic research aircraft completed its first maximum afterburner test at Lockheed Martin’s Skunk Works facility in Palmdale, California. This full-power test, during which the engine generates additional thrust, validates the additional power needed for meeting the testing conditions of the aircraft. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to overcome a major barrier to supersonic flight over land by reducing the noise of sonic booms.Lockheed Martin Corporation/Garry Tice NASA completed the first maximum afterburner engine run test on its X-59 quiet supersonic research aircraft on Dec. 12. The ground test, conducted at Lockheed Martin’s Skunk Works facility in Palmdale, California, marks a significant milestone as the X-59 team progresses toward flight.
      An afterburner is a component of some jet engines that generates additional thrust. Running the engine, an F414-GE-100, with afterburner will allow the X-59 to meet its supersonic speed requirements. The test demonstrated the engine’s ability to operate within temperature limits and with adequate airflow for flight. It also showed the engine’s ability to operate in sync with the aircraft’s other subsystems.
      The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter. The X-59’s first flight is expected to occur in 2025.

      ESA and NASA deliver first joint picture of Greenland Ice Sheet melting
      By European Space Agency
      Global warming is driving the rapid melting of the Greenland Ice Sheet, contributing to global sea level rise and disrupting weather patterns worldwide. Because of this, precise measurements of its changing shape are of critical importance for adapting to climate change.
      Now, scientists have delivered the first measurements of the Greenland Ice Sheet’s changing shape using data from ESA's CryoSat and NASA's ICESat-2 ice missions.

      NASA Sets Coverage for Roscosmos Spacewalk 63 Outside Space Station
      By NASA
      Caption: Expedition 70 Flight Engineer Nikolai Chub from Roscosmos is pictured during a spacewalk to inspect a backup radiator, deploy a nanosatellite, and install communications hardware on the International Space Station’s Nauka science module.Credit: NASA NASA will provide live coverage as two Roscosmos cosmonauts conduct a spacewalk outside of the International Space Station on Thursday, Dec. 19.

      NASA’s live coverage begins at 9:45 a.m. EST, Thursday on NASA+. Learn how to watch NASA content through a variety of platforms, including social media. The spacewalk is scheduled to begin at approximately 10:10 a.m. and last about six and a half hours.

      Expedition 72 crewmates Alexey Ovchinin and Ivan Vagner will venture outside the station’s Poisk module to install an experiment package designed to monitor celestial x-ray sources and new electrical connector patch panels and remove several experiments for disposal. The two cosmonauts also will relocate a control panel for the European robotic arm, which is attached to the Nauka multipurpose laboratory module. Roscosmos cosmonaut Alexsandr Gorbunov will operate the arm during the spacewalk from inside the station.

      Roscosmos spacewalk 63 will be the second for Ovchinin and the first for Vagner. Ovchinin will wear an Orlan spacesuit with red stripes, and Vagner will wear a spacesuit with blue stripes. It will be the 272nd spacewalk in support of space station assembly, maintenance, and upgrades.
