In this one minute exposure, a Geminid meteor streaks across the sky as the Soyuz TMA-19M spacecraft is rolled out by train to the launch pad at the Baikonur Cosmodrome on Sunday, Dec. 13, 2015 in Kazakhstan. The annual Geminid meteor shower peaks on December 13 this year. To get a good look, weather permitting, find the darkest place at night, lay down and look straight up at the sky.

This week in 2017, NASA engineers completed the eighth and final RS-25 rocket engine hot fire test at NASA’s Stennis Space Center. The engine tested included a large 3D-printed part scheduled for use on future RS-25 flight engines that will power the core stage of NASA’S Space Launch System. The part was a beach ball-sized pogo accumulator assembly that acts as a shock absorber to dampen vibrations, or oscillations, caused by propellants as they flow between the vehicle and the engine. The hardware performed as expected, opening the door for more components scheduled for future tests. Today, NASA’s Marshall Space Flight Center is playing a vital role in the Artemis program by developing the SLS, the backbone of NASA’s exploration plans and the only rocket capable of sending humans to the Moon and Mars. The NASA History Program is responsible for generating, disseminating and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA’s activities in aeronautics and space.

Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Dec. 5 deliberately pushed the world’s largest rocket fuel tank beyond its design limits to really understand its breaking point. The test version of the Space Launch System rocket’s liquid hydrogen tank withstood more than 260% of expected flight loads over five hours before engineers detected a buckling point, which then ruptured. Engineers concluded the test at approximately 11 p.m.

The test version of the tank aced earlier tests, withstanding forces expected at engine thrust levels planned for Artemis lunar missions, showing no signs of cracks, buckling or breaking. The test on Dec. 5 -- conducted using a combination of gaseous nitrogen for pressurization and hydraulics for loads -- pushed the tank to the limits by exposing it to higher forces that caused it to break as engineers predicted.

On Monday, Dec. 9, NASA Administrator Jim Bridenstine showed off the Space Launch System liquid-fueled rocket stage that will send the first Artemis mission to space. The core stage, built at NASA’s Michoud Assembly Facility in New Orleans, is the largest NASA has produced since the Apollo Program.

NASA and the Michoud team will shortly send the first fully assembled, 212-foot-tall core stage to the agency's Stennis Space Center near Bay St. Louis, Mississippi aboard the Pegasus barge for final tests.

Surrounded by key NASA personnel and officials from Congress, as well as state and regional government, Bridenstine said the milestone marked a new chapter in the Artemis story as the agency works to answer the charge from to land the first woman and the next man on the Moon by 2024.

In this image, NASA Administrator Jim Bridenstine gives remarks on the agency’s Artemis program, Monday, Dec. 9, 2019, in front of the core stage for NASA’s Space Launch System (SLS) rocket at NASA’s Michoud Assembly Facility in New Orleans.

NASA’s Juno spacecraft captured this impressive image revealing a band of swirling clouds in Jupiter's northern latitudes during Juno’s close flyby on Nov. 3, 2019. Small pop-up storms can also be seen rising above the lighter areas of the clouds, most noticeably on the right side of the image.

This view provides scientists with high-resolution details — the spacecraft skimmed approximately 3,200 miles (5,200 kilometers) above Jupiter's cloud tops at the time it was taken.
