Mars Orbiter Mission Profile
One primary concern is how to get the spacecraft to Mars, on the least amount of fuel. The spacecraft leaves Earth in a direction tangential to Earth's orbit and encounters Mars tangentially to its orbit. Eventually it will intersect the orbit of Mars at the exact moment when Mars is there too. This trajectory becomes possible with certain allowances when the relative position of Earth, Mars and Sun form an angle of approximately 44o.
A Pacific flip triggers the end of the recent slowdown
The slowdown in the rise of average global temperature had been observed in the recent temperature record, but with the last three record years, this slowdown has ceased. Although global temperatures remained at near record levels throughout, variations in decadal climate in the Pacific led to the slowdown in the rise of Global Mean Surface Temperature. The Pacific Decadal Oscillation (PDO) - a pattern of warm and cool phases in Pacific sea-surface temperature - can persist for a decade or more.
How aerial thermal imagery is revolutionizing archaeology
A Dartmouth-led study has demonstrated how the latest aerial thermal imagery is transforming archaeology due to advancements in technology. Archaeologists have long used thermal infrared images to locate buried architecture and other cultural landscape elements. The thermal infrared radiation associated with such archaeological features depends on several variables, including the make-up of the soil, its moisture content and vegetation cover. Now, aerial thermography makes it possible to gather field survey data across a much larger area in much less time.
Scientists: Desert turtle endangered, 100 left in Arizona
It may not be surprising that an aquatic desert turtle faces long odds in life, but environmentalists and biologists still welcomed this week's endangered species designation for the Sonoyta mud turtle. The Sonoyta mud turtle is clearly in danger of extinction, Steve Spangle, a field supervisor with Fish and Wildlife's Arizona Ecological Services, said in a release announcing the listing. Iverson said that the turtle is as safe as it can be, given the circumstances, and that Mexico is where the problem is.
Classified US spy satellite launched from California
A spy satellite for the US National Reconnaissance Office has been launched from Vandenberg Air Force Base in California. All systems were going well when the launch webcast concluded about three minutes into the flight. The launch was expected to be visible across a wide area of California, weather permitting. National Reconnaissance Office satellites gather intelligence information for US national security and an array of other purposes including assessing impacts of natural disasters.
Helping Ponso, sole survivor of 'Chimpanzee Island' in I. Coast
Screeching to see visitors on the forested Chimpanzee Island in Ivory Coast, Ponso is the last, lonely survivor of a colony of 20 apes who mysteriously died or vanished. Chimpanzee Island adjoins the village of Grand-Lahou in the Bandaman estuary, an outlying reach of tropical forest about 100 kilometres from the commercial capital, Abidjan. Only Ponso remains of the group of chimpanzees relocated to the tiny island from Liberia in 1983 by a research laboratory for medical tests.
New quake shakes traumatized Mexico City
Authorities said two people also died in the quake in the southern state of Oaxaca, where the epicenter was located. In a jittery Mexico City, the quake made buildings sway, but some didn't notice. Far, 69 people have been pulled alive from the rubble in Mexico City, according to authorities. The latest death toll stands at 305, of which more than half-167 fatalities-were in Mexico City.
Debate swirls as power of US tech giants grows
With a handful of US technology giants growing more powerful and dominant, debate is intensifying on whether big tech's growth is healthy or not. Along with stalwarts like Microsoft and rising stars like Netflix, the tech firms exercise enormous control over what people see and how they live. Increasingly, policymakers and others have begun to consider breaking up or regulating the biggest technology companies, although imminent action appears unlikely.
Jellyfish don't have brains, but they do sleep
We think of sleep as restoring our brains and a time to process memories to prepare for a new day. Scientists have found that jellyfish go into a sleep-like state, making them the first animal without a brain or central nervous system to do so. The findings push the origin of sleep further down the evolutionary tree of life - to before the emergence of a centralised nervous system.
A Sustainable Future Powered by Sea
Professor Tsumoru Shintake at the Okinawa Institute of Science and Technology Graduate University (OIST) yearns for a clean future, one that is affordable and powered by sustainable energy. Originally from the high-energy accelerator field, in 2012 he decided to seek new energy resources-wind and solar were being explored in depth, but he moved toward the sea instead. The initial phase of the project was successful, and the Unit is now searching for industry partners to continue into the next phase.
DNA editing in human embryos reveals role of fertility 'master gene'
Scientists in Britain have revealed the role of a fertility master gene in one of the world's first demonstrations of DNA editing in human embryos. The study, which marks a first for the UK, could help uncover the cause of recurrent miscarriages and lead to more effective fertility treatments. It also raises ethical questions about the prospect of controversial gene editing techniques being used clinically to correct defects in, or even enhance, human embryos in the future.
Do not panic if your pet ate something toxic, here's what you can do!
One of the most common problems like that is if dogs or cats ingest something toxic. According to reports, American Society for the Prevention of Cruelty to Animals (ASPCA) received over 180,000 calls last year from pet owners whose dogs or cats ingested something toxic. Accidental pet poisoning happens often when it takes in common household stuff that is not edible and is toxic in nature such as laundry detergent, paint thinner or some kind of insecticide.
Delhi Secretariat has an uninvited guest: 2-foot-long monitor lizard causes stir inside premises
An unusual visitor paid a visit to the Delhi Secretariat campus causing a stir inside the premises with many wondering what the creature was. It was a two-foot-long monitor lizard, that was found inside the premises, said officials who rescued it later. The reptile, a non-venomous species, was found trapped inside a turnstile in the lobby area and was later rescued, Wildlife SOS said.
15 vulture species facing extinction set to get global protection
The International Union for Conservation of Nature (IUCN) Red List of species threatened with extinction has listed a majority of these vulture species as critically endangered, indicating a very high risk of extinction in the wild. The cinereous vulture, a wintering migrant to India from Europe, is also facing the threat of extinction. While the Eurasian griffon vulture is found in Europe and Asia, the lappet-faced vulture is home to the Middle East.
A voyage for a cure
A report on her plight appeared across world media and and a few Indian journalists and fund-raisers played a crucial role in facilitating her treatment. The girl is now at Hospital Universitario Virgen de la Victoria. Lamellar ichthyosis is a condition that mainly aects the skin. Infants with this condition are typically born with a tight, clear sheath covering their skin called a collodion membrane. Affected infants could develop infections, an excessive loss of fluids (dehydration), and respiratory problems.
London mayor: Uber to blame for loss of license in city
London's mayor said Saturday that people angry about the decision by transit authorities to strip Uber of its license to operate in the city should blame the ride-hailing company itself. I have every sympathy with Uber drivers and customers affected by this decision, but their anger really should be directed at Uber, Mayor Sadiq Khan said. The city's transportation agency, Transport for London, said Friday that it would not renew Uber's license when it expires Sept. 30, citing a lack of corporate responsibility.
A step closer to treating oral cancer without surgery
The near infrared light heats up the nanoparticles and the heated nanoparticles, in turn, can kill the cancer cells. We are pretty confident that the heat generated by the gold-polymer nanoparticles alone is sufficient to kill the cancer cells. We are planning to carry out clinical trials on people with oral cancer, says Dr De. Oral cancer is largest subset of cancer in India. Besides oral cancer, breast and cervical cancers can also be treated the same way.
When Cassini ended its journey
The US space agency NASA received final signals from its Cassini aircraft last Friday as it ended a journey of 20 years on September 15, 2017 with a meteor-like plunge into the ringed planet's atmosphere. In this handout image, the moon Enceladus and the edge of Saturn are seen from the Cassini spacecraft on its descent towards the planet. The spacecraft, the intrepid robotic explorer of Saturn's magnificent beauty, shot across Saturn's sky, sending pictures till its fiery end.
Strict diet doesn't result in weight loss: Here's why
A small study has revealed that people who did not follow their diet too strictly were found to have shed more weight in comparison to those who followed a strict diet. This study led to the findings that when diets followed by people end, they often result in gaining back of all or most of the weight lost. This research found a possible way to get rid of this issue, which is by taking a break from dieting.
Harvey Flooding Forced The Earth's Crust Down By 2 Centimeters
The Earth's crust (lithosphere) is a rigid solid layer of rock, beneath which is a partially molten layer of rock. In addition, we can measure the deformation of Earth's crust as a result of volcano or mountain building and glacial retreat. Geologists measure deformation in Earth's crust but it's typically on the order of hundreds to more often thousands of years. Both are instances of how humans impact the weight distribution on the lithosphere and thus cause the Earth's crust to sink.
