The four RS-25 engines, which combined flew on 21 shuttle missions, that will be used for the first Space Launch System mission, EM-1. COLUMBIA, Md. — A shift in focus in NASA’s exploration plans to the moon won’t have an immediate effect on planning for the first flight of the agency’s Space Launch System rocket, […]

“Soonish: Ten Emerging Technologies That’ll Improve and/or Ruin Everything” by Kelly and Zach Weinersmith, out Oct. 17, 2017 from Penguin Press. In their new book “Soonish” (Penguin Press, 2017), out today (Oct. 17), Kelly and Zach Weinersmith dig into 10 realms of future technology to see which will survive, which will likely flounder and which […]

Scientists announced Monday (Oct. 16) that the era of multi-messenger astronomy has officially begun. But what does that phrase mean, and how will it change the study of the cosmos?  This new era began with the detection of gravitational waves — ripples in the universal fabric of space-time — produced by two neutron stars merging […]

Telescopes all over the world and in space were busy on Aug. 17, when scientists made the first-ever observations of both light and gravitational waves from a single cosmic event . Here are some of the stunning images of the event, including some from the Hubble Space Telescope, as well as artists’ illustrations that give […]

The Hubble Space Telescope was used to capture imagery of GW170817, the source of gravitational waves detected on Aug. 17, 2017. On Aug. 17, 2017, gravitational waves from a neutron-star collision were detected for the first time ever by LIGO and Virgo collaborations and – in another first – light from the event has been captured […]

For the first time, scientists have detected ripples in the fabric of space and time — known as gravitational waves — from a colliding pair of dead stars called neutron stars . This is the first time astronomers have witnessed two neutron stars merging, and these new findings may help solve the decades-old mystery of how […]

A new era of astronomy has begun. For the first time ever, scientists have spotted both gravitational waves and light coming from the same cosmic event — in this case, the cataclysmic merger of two superdense stellar corpses known as neutron stars. The landmark discovery initiates the field of “multimessenger astrophysics,” which promises to reveal exciting […]

Visualization of a star merger that produces gravitational waves. For the first time, gravitational waves from the merger of two neutron stars has been detected and its source has been visually observed with telescopes. The LIGO and Virgo collaborations first detected the gravitational waves on Aug. 17, 2017, and the sky coordinates of its source were […]

The long-anticipated film “Blade Runner 2049” heralds the return of the replicants, uncannily life-like robots who, in the 1982 “Blade Runner” film, rebelled against their human overlords with mixed results and were subsequently hunted and brutally “retired” by a specialized police officer. Androids — constructs that combine artificial intelligence and a mechanical body with a […]

Venus and Mars shine near the crescent moon in the eastern sky before dawn on Tuesday, Oct. 17, 2017. A gathering of two bright planets and the slender crescent moon will be the chief celestial attraction in the predawn sky Tuesday (Oct. 17). If you look low toward the eastern horizon about 60 to 75 […]

An uncrewed Russian cargo ship arrived at the International Space Station early Monday (Oct. 16) to deliver nearly 3 tons of fresh food, fuel and other supplies.  The Progress 68 resupply ship linked up with the space station at 7:04 a.m. EDT (1104 GMT) as the two spacecraft sailed 252 miles (405 kilometers) over eastern […]

Although Robonaut 1 was never meant to fly in space, NASA tested the technology on the ground before launching its successor, Robonaut 2, in 2011. Robonaut was created in collaboration with the Defense Advanced Research Projects Agency (DARPA), a branch of the U.S. military that invests in far-flung technology projects. Robonaut 2 has been on […]

WASHINGTON — ASRC of Beltsville, Md., has test fired a subscale propellant injector built via additive manufacturing , or 3D printing, paving the way for a version that could support whichever engine United Launch Alliance chooses to replace the Russian-built RD-180 on the Atlas 5 rocket. ASRC’s Federal Technical Services division conducted the full-power test in […]
