Nadezda Murmakova/Shutterstock When you think of a shuttle or rocket launching into space, odds are the Kennedy Space Center comes to mind. After all, some of the most momentous expeditions, including the Apollo missions, took off from the center’s very own Launch Complex (LC) 39A. In 2014,
Studying preserved footprints in New Mexico continues to provide insight into the first human movements in North America. A research team believes the footprints are more than 23,000 years old, confirming an earlier study that dates the prints to 10,000 years older than previously believed. Tracking the footsteps provides modern scientists a view into ancient
Paleontologists have unearthed fossilized bones of one of the smallest sauropodomorph dinosaurs from the Late Triassic of southern Brazil, offering fresh insights into early dinosaur development and physiology.

CAPE CANAVERAL, Fla. (AP) – NASA began another practice launch countdown Tuesday for its first moonshot with astronauts in decades, after making repairs to fix dangerous fuel leaks that already have bumped the flight into March. The first fueling test was halted two weeks ago by the same kind of liquid hydrogen leaks that disrupted
At just 500 kilometers across, Saturn‘s sixth-largest moon would fit comfortably inside the United Kingdom, with room to spare. Yet new research reveals this tiny ice world wields electromagnetic influence over distances exceeding half a million kilometers, more than the distance between Earth and the Moon. The discovery comes from a comprehensive analysis of data
Mars may have been much warmer and wetter billions of years ago than previously thought, according to new findings from NASA’s Perseverance Rover. The discovery challenges earlier theories that the Red Planet was predominantly cold and icy during a time when it may have been habitable. Mars’ history has long been a subject of intense
The Milky Way shines over the Very Large Telescope in Chile. (Image credit: A. Trigo/ESO) The European Southern Observatory has released a breathtaking photo of the Milky Way shining over the Paranal Observatory in Chile, as lasers create artificial “guide stars” in the pristinely dark sky above. What is it? Stars, satellite streaks, galaxies and
A rare Stone Age cemetery on a Swedish island reveals that some of Europe’s last hunter-gatherers were buried not with their extremely close relations but with more distantly related people, according to a new DNA analysis. However, some burials had close biological family members, including that of a teenage girl whose father’s jumbled bones had
Cell culture Cells were grown in complete DMEM medium (D5796, containing 4,500 mg l−1 glucose, 2 mM L-glutamine) supplemented with dialysed 10% FBS (Sigma-Aldrich, F7524), 1% penicillin–streptomycin (PenStrep, Lonza), at 37 °C in an atmosphere of 5% CO2 and 95% air. Where indicated, 50 μg ml−1 uridine and/or 1 mM sodium pyruvate (Sigma-Aldrich) were added to the growing media. Inhibitors were purchased
Episode description: Behind NASA’s Artemis II mission and the astronauts who will fly around the Moon, teams on the ground are essential. Explore some of the epic equipment that makes Artemis II possible—the mobile launcher, crawler-transporter, and NASA’s barge Pegasus—and meet a few of the many specialists who act as the shoulders lifting astronauts into
