The largest 3-D printed rocket engine component NASA hsa ever tested blazed to life Thursday, Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust. This test is a milestone for one of many important advances the agency is making to reduce the cost of space hardware.
In 2003, the Helios solar electric airplane broke up in mid-air and crashed into the Pacific Ocean. The incident highlighted a problem: Operators of unmanned aerial vehicles (UAVs) had no way of knowing when the wings were experiencing unsustainable strain. Scientists at NASA’s Dryden Flight Research Center and 4DSP, a company specializing in signal and image processing systems, co-developed a lightweight, robust Fiber Optic Sensing System (FOSS) that greatly speeds the operational monitoring and sensing.
The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year. While the ice will continue to shrink until around mid-September, it is unlikely that this year’s summer low will break a new record. Still, this year’s melt rates are in line with the sustained decline of the Arctic ice cover.
On Tuesday, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon which can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.
In two NASA-funded studies, biofilms made by the bacteria Pseudomonas aeruginosa were cultured on Earth and aboard space shuttle Atlantis in 2010 and 2011 to determine the impact of microgravity on their behavior. After comparing the biofilms grown on the ground with those grown on space station-bound shuttles, study results show for the first time that spaceflight changes the behavior of bacterial communities.
Carrying Earthly greetings on a gold plated phonograph record and still-operational scientific instruments NASA's Voyager 1 has traveled farther from Earth than any other human-made object. And now, researchers say, it has begun the first exploration of our galaxy beyond the Sun's influence. The finding could be, however, somewhat controversial.
A meteor weighing 10,000 metric tons exploded 14 miles above Chelyabinsk, Russia, on Feb. 15, 2013. Unlike similar past events, this time scientists had the sensitive instruments on the Suomi NPP satellite to deliver unprecedented data and help them track and study the meteor plume for months.
Six researchers have spent the past four months living in a small dome on a barren Hawaii lava field at 8,000 feet, trying to figure out what foods astronauts might eat on Mars and during deep-space missions. They emerged on Tuesday with their recipes and without the space suits they were required to wear each time they ventured onto the northern slope of Mauna Loa—an active volcano that last erupted in 1984.
A recent arrival to NASA’s Kennedy Space Center in Florida, the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft will have quite a different approach than that taken by recent probes dispatched to the Red Planet. Instead of rolling about on the surface looking for clues to the planet's hidden heritage, MAVEN will orbit high above the surface so it can sample the upper atmosphere for signs of what changed over the eons and why.
Astronomers have solved a 40-year-old mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy. It appears to originate from two dwarf galaxies, but astronomers did not know if one or both galaxies were the source. Hubble Space Telescope’s Cosmic Origins Spectrograph was used to examine the gas and find the answer.
Curiosity Rover team members re-live the dramatic Aug. 6, 2012 landing and the mission's achievements to date in a recent event aired on NASA Television and the agency's website. In the year since inspiring millions of people worldwide with its one-of-a-kind landing in a crater on the Red Planet, Curiosity has achieved its primary scientific objective; finding evidence that ancient Mars could have sustained microbial life.
Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b and still glowing from the heat of its formation, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.
The Severe Storm Sentinel, or HS3, mission will fly this year to investigate Atlantic Ocean hurricanes. It will carry a new type of dual-frequency conical-scanning Doppler radar that sports a new shape: Most aircraft carrying Doppler radar look like they’ve grown a tail, developed a dorsal fin, or sprouted a giant pancake on their backs. But the unmanned Global Hawk carries will carry the radar under its belly as it flies above hurricanes.
The GOES-R Magnetometer Engineering Development Unit at NASA’s Goddard Space Flight Center completed successful boom deployment test at an ATK facility in Goleta, Calif. The magnetometer, which will deploy aboard the boom after launch, will provide measurements of the space environment magnetic field, which controls charged particle dynamics in the outer region of the magnetosphere.
After studying data from a pair of NASA probes roaming the harsh space environment within the Van Allen radiation belts, researchers at Los Alamos National Laboratory believe they have solved a lingering mystery about how electrons within Earth’s radiation belt can suddenly become energetic enough to kill orbiting satellites.
On July 17, 2013, the international team which supported and built NASA's Interface Region Imaging Spectrograph, or IRIS, was rewarded for its hard work when the door of the telescope opened to view the mysterious lowest layers of the sun's atmosphere in unprecedented detail. Imaging in ultraviolet light and using a spectrograph, the orbiter has already revealed a multitude of previously unseen structures.
New findings from NASA's Curiosity rover provide clues to how Mars lost its original atmosphere, which scientists believe was much thicker than the one left today. The beauty of these measurements lies in the fact that these are the first really high-precision measurements of the composition of Mars' atmosphere.
Recovery efforts to save the $600 million Kepler mission began Thursday and will last for a week. Mission managers won't know until later this month at the earliest whether the Kepler spacecraft will ever search for Earth-like planets again.
Biotechnology company Zero Gravity Solutiuons aims to utilize the unique effects of extended zero/micro gravity environments available on the International Space Station to promote gene expression and accelerate stem cell research. The company has completed filings required prior to trading of the company’s stock.
The next rover to Mars should hunt for signs of ancient life and gather rocks that a future mission could bring back to Earth for the first time, a team of scientists appointed by the U.S. space agency said Tuesday. The scientists' new report outlines ambitious goals for a mission to Mars that NASA wants to launch in 2020.
Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy. This process lies at the heart of giant explosions on the sun.
Astronomers have for the first time managed to determine the color of a planet outside our solar system, a blue gas giant 63 light-years away. Measuring the planet's color, which is probably created by a turbulent atmosphere of silicate particles, is a significant first. It has never been done before with a planet outside our solar system.
From its perch in low-Earth orbit, NASA's newest satellite will soon get a close-up look at a little-explored region of the sun that's thought to drive space weather that can affect Earth. The Iris satellite was boosted into orbit about 400 miles above Earth by a Pegasus rocket Thursday evening after a sunset launch. Engineers will test the satellite first before turning on its telescope to stare at the sun.
According to NASA, there are more than 21,000 pieces of “space junk roughly the size of a baseball in orbit, and about 500,000 pieces that are golf ball-sized. These pieces can be dangerous, which is why researchers at Texas Advanced Computing Center’s supercomputers are simulating orbital debris impacts on spacecraft and fragment impacts on body armor to help NASA design better shielding.
Using data gathered by NASA’s Lunar Reconnaissance Orbiter mission, scientists believe they have solved a mystery from one of the solar system’s coldest regions—a permanently shadowed crater on the moon. They have explained how energetic particles penetrating lunar soil can create molecular hydrogen from water ice. The finding provides insight into how radiation can change the chemistry of water ice throughout the solar system.
