The large amount of jet fuel required to fly an airplane from point A to point B can have negative impacts on the environment and a traveler's wallet. With funding from NASA and the Boeing Company, engineers from Caltech and the Univ. of Arizona have developed a device that lets planes fly with much smaller tails, reducing the planes' overall size and weight, thus increasing fuel efficiency.
The findings of NASA’s planet-hunting Kepler spacecraft suggest that the most common exoplanets are those that are just a bit larger than Earth but smaller than Neptune. These so-called super-Earths, which do not exist in our own solar system, have attracted the attention of astronomers, who have been trying to determine the composition of the closest of these planets. However, an unexpected barrier is blocking their progress.
Washington State University undergraduate Kellie Wall, 21, recently looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock observations made by the rover Curiosity on Mars’ Gale Crater, inventing a new method for detecting water on Mars.
Astronomers using data from NASA's space telescopes Hubble, Spitzer, and Kepler have discovered clear skies and steamy water vapor on a gaseous planet outside our solar system. The planet is about the size of Neptune, making it the smallest planet from which molecules of any kind have been detected.
The robotic explorer Maven successfully slipped into orbit around Mars late Sunday night. Now the real work begins for the $671 million mission, the first dedicated to studying the Martian upper atmosphere and the latest step in NASA's bid to send astronauts to Mars in the 2030s. Researchers hope to learn where all the red planet's water went, along with the carbon dioxide that once comprised an atmosphere thick enough to hold moist clouds.
A SpaceX cargo ship rocketed toward the International Space Station on Sunday, carrying more than 5,000 pounds of supplies, including the first 3-D printer for astronauts in orbit. The printer, developed by Made in Space, is sturdier than Earthly models and is a technology demonstrator. . But NASA envisions astronauts one day using one to crank out spare parts as needed.
Mars, get ready for another visitor or two. This weekend, NASA's Maven spacecraft will reach the red planet following a 10-month journey spanning 442 million miles (711 million km). If all goes well, the robotic explorer will hit the brakes and slip into Martian orbit Sunday night.
On Monday, NASA's inspector general released a report blasting the agency’s Near Earth Objects program, which is meant to hunt and catalog comets, asteroids and relatively large fragments of these objects that pass within 28 million miles of Earth. The purpose is to protect the planet against their potential dangers, but only 10% of the near-Earth objects bigger than 460 ft across have been catalogued, well short of the goal of 90% by 2020.
Workers at Kennedy Space Center gathered to watch as the Orion capsule, NASA's new spacecraft for humans, emerged from its assembly hangar Thursday morning, less than three months from its first test flight. During its Dec. 4 test flight, the capsule, unmanned, will shoot more than 3,600 miles into space and take two laps around Earth before re-entering the atmosphere at 20,000 mph and parachuting into the Pacific off the San Diego coast.
Putting three radars on a plane to measure rainfall may seem like overkill. But for the Integrated Precipitation and Hydrology Experiment field campaign in North Carolina recently, more definitely was better. The system is specifically designed to measure rain in difficult-to-forecast mountain regions, where a wide range of frequencies to need be covered so that researchers can detect the more than 30 varieties of rainfall.
A Purdue Univ. student team has designed, built and tested a critical part of a new a rocket engine as part of a NASA project to develop spacecraft technologies needed to land on the moon, Mars and other cosmic venues. The students are making a central part of the new engine—called the thrust chamber or combustor—as part of NASA's Project Morpheus.
Laser technology originally developed at Los Alamos National Laboratory for the Mars Science Laboratory has been selected for NASA’s new Mars mission in 2020. The Curiosity rover is equipped with ChemCam, which allows researchers to sample rocks and other targets from a distance using a laser. The new “SuperCam” will offer this capability along with another spectrum for Raman and time-resolved fluorescence spectroscopy.
The million-mile-per-hour solar wind pushed out by the Sun inflates a giant bubble in the interstellar medium called the heliosphere, which envelops the Earth and the other planets. At the 40th International Committee on Space Research (COSPAR) Scientific Assembly in Moscow this week, scientists highlighted an impressive list of achievements in researching the outer heliosphere, which barely registered as a field of research ten years ago.
Taking fuel to Mars for return flights is heavy and expensive. The $1.9 billion Mars 2020 rover that NASA announced on Friday will include an experiment that will turn carbon dioxide in the Martian atmosphere into oxygen. It could then be used to make rocket fuel and for future astronauts to breathe. The device, named MOXIE, will make about three-quarters of an ounce of oxygen an hour.
At a press conference in Washington on Thursday, NASA announced the instruments to be designed into the Mars 2020 rover, a mission that will be based on the design of the highly successful Mars Science Laboratory rover, Curiosity, which landed almost two years ago. Managers made the selections out of 58 proposals received in January from researchers and engineers worldwide.
New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy x-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB.
In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA's Fermi Gamma-ray Space Telescope. It was as if someone flipped a switch on the pulsar.
A heat-sensing camera designed at Arizona State University has provided data to create the most detailed global map yet made of Martian surface properties. THEMIS, the nine-band visual and infrared camera on NASA’s Mars Odyssey orbiter, was used to create this map, which is now available online. And citizen scientists are invited to help make it even better.
One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Theories abound, but probes sent by NASA have recently provided the first really strong confirmation of what's happening. For the first time, scientists can explain how the electrons are accelerated up to nearly the speed of light.
Scientists analyzing data from NASA’s Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea. The new results come from a study of gravity and topography data collected during Cassini's repeated flybys of Titan during the past 10 years. The finding may change some scientists' expectations for present-day life on the distant moon.
NASA has tested new technology designed to bring spacecraft safely down to Mars, with the agency declaring the experiment a qualified success even though a giant parachute got tangled on the way down. Saturday's $150 million experiment is the first of three involving the Low Density Supersonic Decelerator vehicle, which creates atmospheric drag to dramatically slow the spacecraft from Mach 4.
Space may appear empty, a soundless vacuum. But it's not an absolute void. It flows with electric activity that is not visible to our eyes. NASA is developing plans to send humans to an asteroid, and wants to know more about the electrical environment explorers will encounter there. A new computer model can now predict and visualize the interaction between the solar wind, solar radiation and the surface of asteroids in unprecedented detail.
A new congressionally mandated report from the National Research Council concludes that the expense of human spaceflight and the dangers to the astronauts involved can be justified only by the goal of putting humans on other worlds. The authors recommend a disciplined “pathway” approach that eventually leads to the “horizon goal” of putting humans on Mars.
A new NASA panorama looking deep and far into the universe for the first time includes ultraviolet light, which is normally not visible to the human eye. It shows up in the photo as bright baby blue with spinning galaxies, which are about 5 to 10 billion years old. The photo is a composite of more than 800 photos taken by Hubble and shows about 10,000 multi-colored galaxies.
The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet. For decades, robotic landers and rovers have hitched a ride to Earth's planetary neighbor using the same parachute design, but NASA needs a bigger and stronger parachute if it wants to send astronauts there.
