Scientists have pieced together the sequence of events of the farthest touchdown a man-made spacecraft has ever made on an alien world. Their work in tracking the bounces, wobbles, and skids the probe made before coming to rest on Titan reveals new clues about the Saturn moon’s surface and helps plan future missions to moons and planets.
Two instruments on the Mars rover Curiosity were used to study the chemical makeup of a football-size rock called "Jake Matijevic". In addition to the ChemCam, which had examined a number of rocks, NASA for the first time used an X-ray spectrometer on the new rock, finding that its composition resembles some unusual rocks found in Earth’s interior.
A commercial cargo ship rocketed into orbit Sunday in pursuit of the International Space Station, the first of a dozen supply runs under a mega-contract with NASA. It was the second launch of a Dragon capsule to the orbiting lab by the California-based SpaceX company. This time was no test flight, however, and the spacecraft carried 1,000 pounds of key science experiments and other precious gear.
The Hubble constant is named after the astronomer Edwin P. Hubble, who astonished the world in the 1920s by confirming our universe has been expanding since it exploded into being 13.7 billion years ago. This constant, or rate of expansion, is accelerating, and determining the expansion rate is critical for understanding the age and size of the universe. Astronomers using NASA's Spitzer Space Telescope have announced the most precise measurement yet of the Hubble constant.
The NASA rover Curiosity has beamed back pictures of bedrock that suggest a fast-moving stream, possibly waist-deep, once flowed on Mars. There have been previous signs that water existed on the red planet long ago, but the images released Thursday showing pebbles rounded off, likely by water, offered the most convincing evidence so far of an ancient streambed.
NASA’s Hurricane and Severe Storm Sentinel (HS3) investigation is a five-year mission to better understand the processes that underlie hurricane intensity change in the Atlantic Ocean basin. The Global Hawk is a key part of that effort, and its flights into the hurricane’s environment allow several highly-advanced, autonomously operated instruments to gauge everything from wind speed to cloud structures.
An important test is coming up next week to see whether a heat shield made from the soil of the moon, Mars, or an asteroid will stand up to the searing demands of a plunge through the Earth's atmosphere. At stake is the possibility that future spacecraft could leave Earth without carrying a heavy heat shield and instead make one on the surface of another world and ride it home safely.
The NASA Goddard Space Flight Center has awarded a SBIR Phase II program to Tahoe RF Semiconductor Inc. for developing a miniaturized Radiation Hardened Beam-Steerable GPS Receiver Front End for NASA spacecrafts.
This week, design company 4DSP has launched live industry demonstrations of licensed NASA fiber optic sensing and 3D shape rendering technology. Past fiber optic sensing solutions have been limited by both processing speed and high deployment costs, and 4DSP expects the new technology to offer a 20-fold improvement in performance.
Tracks from the first drives of NASA's Curiosity rover are visible in a new image captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. In just one month, it's driven 112 m on the red planet, slightly more than the length of a football field.
Today marks the 35th anniversary of Voyager 1's launch to Jupiter and Saturn. Since leaving the ringed gas giant behind many years ago, Voyager 1 has rocketed toward an invisible boundary that no human spacecraft has ever ventured beyond. Scientists now say, based on instrument readings, that it is about to leave our solar system and venture into interstellar space.
Scientists using the Mini-RF radar on NASA's Lunar Reconnaissance Orbiter have successfully estimated the maximum amount of ice likely to be found inside a permanently shadowed lunar crater located near the moon's South Pole. Their results, which offer more definite support to prior findings, show as much as 5 to 10% of the material, by weight, could be patchy ice.
Twin U.S. satellites rocketed into orbit Thursday on a quest to explore Earth's treacherous radiation belts and protect the planet from solar outbursts. It's the first time two spacecraft are flying in tandem amid the punishing radiation belts, brimming with highly charged particles capable of wrecking satellites and endangering astronauts.
When the Space Shuttle Atlantis took off from Cape Canaveral on its final flight more than a year ago, a research team took advantage of this opportunity to track the 350-ton plume of water vapor exhaust that it released shortly after launch. Crossing through the paths of seven separate sets of instruments, the vapor spread far faster than expected and quickly moved to the Arctic. Such information will be used to inform global circulation models.
In addition to releasing spectacular new telephoto images of the Martian surface, NASA also used the rover to relay a voice message from NASA’s administrator, Charles Bolden, from Earth to Mars and back. The new images were taken by the 100-mm telephoto lens and the 34-mm wide angle lens of the Mast Camera instrument, which photographed the lower slopes of Mount Sharp.
When man first harnessed fire, no one recorded it. When the Wright Brothers showed man could fly, only a handful of people witnessed it. But when Neil Armstrong took that first small step on the moon in July 1969, an entire globe watched from a quarter million miles away. Although more than half of the world's population wasn't alive then, it was an event that changed and expanded the globe.
Curiosity’s test drive was a success, allowing scientists at NASA to begin planning their next move. An intriguing spot 1,300 feet will mark the rover’s first attempt to drill into bedrock. The ultimate destination is Mount Sharp, a towering mountain that looms from the ancient crater floor. Signs of past water have been spotted at the base, providing a starting point to hunt for the chemical building blocks of life.
A scientific report on NASA Glenn Research Center’s Polyimide Aerogels, which won an R&D 100 Award this year, was part of the presentations at the American Chemical Society meeting in Philadelphia this week. The new material is the lightest commercially available solid material, and is far tougher than the silicon-based aerogels that preceded it.
NASA has awarded the California Institute of Technology a new five-year contract to manage the agency's Jet Propulsion Laboratory (JPL). The contractor's primary mission is to support NASA's Science Mission Directorate (SMD) in carrying out specific objectives identified in the SMD Science Plan. The contract is for $8.5 billion.
Scientists using NASA's Chandra X-Ray telescope have found a galaxy that gives births to more stars in a day than ours does in a year. Even more puzzling to astronomers than its prolific nature its age. At 6 billion years old, the large, mature galaxy shouldn’t be producing that many stars.
Scientists using the Lyman Alpha Mapping Project spectrometer aboard NASA's Lunar Reconnaissance Orbiter (LRO) have made the first spectroscopic observations of the noble gas helium in the tenuous atmosphere surrounding the moon. These remote-sensing observations complement in situ measurements taken in 1972 by the Lunar Atmosphere Composition Experiment deployed by Apollo 17.
Locale aside, Curiosity is giving scientists an unprecedented sense of what it took to reach its Martian destination. A low-quality video of the landing and the first color picture arrived quickly. Now, spectacular images of the crate in which the rover landed are beginning to arrive, and the best views—of Mars and the journey there—are yet to come.
NASA recently picked three aerospace companies to build small rocketships to take astronauts to the International Space Station. This is the third phase of NASA's efforts to get private space companies to take over the job of the now-retired space shuttle. The companies will share more than $1.1 billion. Two of the ships are capsules like in the Apollo era and the third is closer in design to the space shuttle.
NASA's Curiosity rover on Monday transmitted a low-resolution video showing the last 2 1/2 minutes of its white-knuckle dive through the Mars atmosphere, giving Earthlings a sneak peek of a spacecraft landing on another world. It was a sneak preview since it'll take some time before full-resolution frames are beamed back depending on other priorities.
The relentless, weather-gone-crazy type of heat that has blistered the United States and other parts of the world in recent years is so rare that it can't be anything but man-made global warming, says a new analysis from NASA’s James Hansen. In a departure from most climate research, which is based on modeling, the new study relies on statistics.
