Washington D.C. [USA], Apr. 11 : Tropical Cyclone Cook formed in the Southern Pacific Ocean and on Sunday, April 9, 2017 and moved across the island of New Caledonia in the South Pacific Ocean on early on April 10. NASA-NOAA's Suomi NPP Satellite passed over Cook as it was making landfall.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite provided a visible image of Cook on April 10 at 0254 UTC (April 9 at 10:54 p.m. EST). That was about one hour before the storm's center made landfall in central New Caledonia. The image showed a cloud-filled eye surrounded by powerful thunderstorms. A large band of thunderstorms feeding into the center blanketed the islands of Vanuatu.
Washington D.C. [USA], Mar. 30 : Astronauts may soon be able to communicate faster to and from space as NASA's advanced laser communications system called LEMNOS has brought speedy connections closer to the reality.
Imagine being able to watch 4K ultra-high-definition (UHD) video as humans take their first steps on another planet. Or imagine astronauts picking up a cell phone and video-conferencing their family and friends from 34 million miles away, just the same as they might on Earth. LEMNOS, Laser-Enhanced Mission and Navigation Operational Services, may make these capabilities and more a reality in the near future.
Washington D.C. [USA], Mar. 16 : Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet,were discovered more than 50 years ago, but their behaviour is still not completely understood.
Now, new observations from NASA's Van Allen Probes mission show that the fastest, most energetic electrons in the inner radiation belt are not present as much of the time as previously thought.
The results show that there typically isn't as much radiation in the inner belt as previously assumed, which is good news for spacecraft flying in the region.
New Delhi [India], Mar. 4 : NASA's Mars Atmosphere and Volatile Evolution Mission (MAVEN), which is in its second year of studying the Red Planet's atmosphere, was recently forced to perform unscheduled maneuver to avert a space-wreck.
In its first collision avoidance maneuver, MAVEN spacecraft carried out a rocket motor burn that boosted its velocity by 0.4 meters per second (less than 1 mile per hour) to steer clear of Mars' moon Phobos, NASA reported.
The correction was small, but it was enough for the spacecraft to avoid the crater-filled moon by about 2.5 minutes.
New Delhi [India], Feb. 23 : Google has always made sure to celebrate every special affair around the globe.
Likewise, it has dedicated its doodle today to NASA's discovery of seven earth sized exoplanets.
In a short, comical animation, the doodle shows NASA's Spitzer Space Telescope, which revealed the first known system of seven Earth-size planets around a single star.
The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water - key to life as we know it - under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
New York [USA], Feb. 17 : NASA has called on the world to help it in the search for the new ninth planet, as anyone from a kindergartener to a 95-year-old, can participate in their new project to find the not-yet-discovered celestial body.
To let anyone participate in this search project of ninth planet, the Zooniverse space projects site has launched a NASA-funded venture, Backyard Worlds: Planet 9, reports CNN.
"There are really low barriers to entry," Dr. Laura Trouille of Zooniverse.
NASA has compiled a "flipbook" of short animations that shows sky scans taken over several years and so far, 4,201 people have joined the mission.
The participants can search for disruptions in the images -- basically, clusters of tiny coloured dots -- and mark their findings.
NASA’s Mars rover Opportunity has been exploring the Red Planet for more than a decade. Like a champion, it tackled all the difficulties that it faced during its journey on the planet. But now, the rover has got stuck on a hill. NASA officials and scientists in the project have made a bold decision to make the rover climb the hill.
As per NASA report, the rover got stuck when it was exploring the slopes of ‘Marathon Valley’. The region is in Meridiani Planum of Mars. NASA’s Jet Propulsion Laboratory announced that the Opportunity rover will attempt to climb the slope. It will be the most extreme slope the rover has faced in its more than a decade mission on the Red Planet.
Orbital ATK is among the two private companies that presently hold a contract with the US space agency NASA for flying unmanned cargo missions to the International Space Station (ISS). The formation of the company took place with a merger of Orbital Sciences Corp. and Alliant Techsystems (ATK).
Specialized in launching tiny satellites, Orbital Sciences was best known for the Cygnus cargo spacecraft launch to the ISS, and ATK gained prominence by making solid rocket boosters for the space shuttles. Since the merger in February 2015, Orbital ATK has been working on defense systems, flight systems and space systems.
The National Aeronautics and Space Administration (NASA) used its Spitzer Space Telescope for creating a precision temperature (exo-) map of a nearby ‘super-Earth’ exoplanet, known as 55 Cancri e. This is the first of its kind graphical representation for the heat data available for such an exoplanet, which is located at a distance of 40 light years from Earth and is situated in the constellation of Cancer.
Astronomers investigating data and images beamed back by NASA's New Horizons spacecraft have found that dwarf planet Pluto once have had flowing lakes of nitrogen. The team concluded the new findings after studying details of body of nitrogen on the dwarf planet seen in a new picture.
New Horizons team announced that Pluto may once have harbored lakes of nitrogen, not water, billions of years ago when its surface conditions were different from today. The distant world’s thicker atmosphere raised the temperature and created an environment where liquid nitrogen flowed on the surface, the team added.
The more we understand about dwarf planet Pluto, the more confusing it becomes. New set of data sent by NASA’s New Horizons spacecraft revealed that the distant planet had lakes on its surface in the past. Before this, it was thought that Pluto only has an ocean under its frozen surface.
The data collected by the spacecraft during its flyby of Pluto last year in July also suggested that the planet in the Kuiper belt may have a nitrogen lake on its surface in future. NASA has released a new image confirming that there were liquid channels on the surface of Pluto millions or billions of years ago.
NASA has planned eight major projects that will be undertaken over a period of coming six months. The research projects will range from Greenland ice sheet to the coral reefs of the South Pacific. The purpose of this scientific investigations campaign is to understand the extent to which the Earth is changing and how humans are affecting this change.
"Combining the long-term global view from space with detailed measurements from field experiments is a powerful way of deciphering what's happening in our world," said the Director of NASA's Earth Science Division, Michael Freilich.
NASA's Cassini mission scientists have identified the highest peak on Titan, largest moon of planet Saturn. The tallest peak on Titan is 10,948 feet high, the research team said.
They have also discovered that all of the highest peaks on Titan are roughly 10,000 feet in elevation. The study has revealed surfaces in-depth using pictures and other data from Cassini's radar instrument.
Stephen Wall, deputy lead of the Cassini radar team at NASA, said that the point discovered by them isn’t just the highest point they have found on Titan so far, but they also think that it’s the highest point they would ever find there. Most of the tallest mountains on Titan are apparently near to the equator.
American space agency NASA has released some new close-up images of Ceres, revealing the dwarf planet’s mysterious bright spots in unprecedented detail.
The images, captured by the space agency’s space probe Dawn from just 240 miles above the surface, provides a closer look at Ceres surface that shows distinctive bright spots. The images unveil a dome covered with the bright material.
For the first time, scientists could look at the dwarf planet’s Occator Crater. The crater, which measures around 2.5 miles deep and 57 miles across, contains the two bright spots that perplexed researchers for years.
However, even the new images failed solve the mystery of bright spots, but the images finally provided scientists with something to work with.
A team of planetary scientists has proposed a new theory stating that the Moon, Earth’s natural satellite, has shifted off its original axis by roughly 6 degrees over the course of a billion years. This shift might have happened due to violent volcanic activity, nearly three billion years ago. Southern Methodist University, Dallas Planetary scientist Matt Siegler and his team has worked on the project.
After checking data collected by NASA missions, Siegler added giant mass of molten material could have caused a change in internal balance of lunar center of gravity. The study has been published in the journal Nature.
For the first time ever, scientists have managed to see a star going supernova in visible light. The Kepler space telescope captured two exploding stars in 2011. At that time, explosion of two red supergiants took place in what are known as Type II supernovae.
Type II supernovae occur when the core of the star collapses and explodes violently in fast succession. Such kind of explosion’s shockwaves or shock breakout lasts just around 20 minutes due to which recording one of the events is a remarkable achievement for astronomy.
With the help of NASA's Chandra X-Ray Observatory, a UCL-led research team found that solar storms have triggered Jupiter’s intense ‘Northern Lights’ by producing a new X-ray aurora that is eight times brighter compared to normal and hundreds times more energetic in comparison to Earth’s aurora borealis.
This is for the first time ever that Jupiter's X-ray aurora has been analyzed during the arrival of a huge storm from the Sun at the planet.
The striking findings go together well with NASA's Juno mission this summer which is looking forward to understand the link between the two largest structures in the solar system, including the area of space managed by Jupiter's magnetic field and the region under the control of solar wind.
Late Tuesday, commercial Cygnus cargo ship was launched into space. Streaking into the Florida night sky, it is on a delivery mission, carrying a record-setting load of NASA experiments and gear to the International Space Station (ISS).
Yesterday, at 11:05 pm the Orbital ATK-built Cygnus blasted off atop an Atlas V rocket EDT in a smooth liftoff from Cape Canaveral Air Force Station. Packed with over 3.5 tons of supplies, the cargo ship is likely to arrive at the space station early on March 26.
The flight is the second for Orbital ATK's improved Cygnus craft on an Atlas V rocket given by the United Launch Alliance. The company representatives said that the cargo ship has onboard even more cargo as compared to the Orbital ATK's last record-breaking flight in December.
As part of its Mars exploration initiative, American space agency NASA has released a new gravity map of the red planet that is believed to have the potential of providing minutest and most detailed look of the planet’s unforeseen interiors. The improved resolution may help scientists crack certain mysteries associated with various regions of the planet that still continue to perplex humans.
The gravity maps play the same role in scanning the inside of a planet as a doctor does while conducting an X-ray to see the close organ details of a patient, said Antonio Genova from the Massachusetts Institute of Technology (MIT) in a NASA press release.
A Soyuz rocket carrying a space team of three astronauts was launched on Friday from the Baikonur Cosmodrome in Kazakhstan. Now, the crew, including one NASA astronaut and two cosmonauts, has reached the International Space Station (ISS) safely.
A pair of Roscosmos cosmonauts—Oleg Skripochka and Aleksey Ovchinin—and American astronaut Jeff Williams arrived at the ISS after a journey of about six hours. With the latest mission, the 58-year-old NASA astronaut, Jeff Williams, will break another NASA astronaut Scott Kelly’s record by spending 534 cumulative days aboard the space station. Kelly has lived 520 days in space at the ISS.
The trio, flying on a Soyuz space capsule, was welcomed by NASA astronaut Tim Kopra, ESA astronaut Tim Peake and Russian cosmonaut Yuri Malenchenko.
