The Ion and Neutral Mass Spectrometer saw a much higher density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected. This dramatic increase in density was evident as the spacecraft flew over the area of the plumes.
Previous analyses inferred three different spectral types of Enceladean ice grains (Postberg et al. 2008, 2009a): Type 1 represents grains of almost pure water ice, Type 2 shows features consistent with grains containing significant amounts of organic material, and Type 3 is indicative of salt-rich water ice grains.
Before NASA’s Cassini mission studied Saturn and its moons for 13 years, beginning in 2004, Enceladus held many secrets. Cassini revealed that there was a global ocean between the moon’s icy crust and its rocky core.
Although the Cassini mission ended in a blaze of glory when it disintegrated in Saturn’s atmosphere, surprises from the data it collected will be released for years to come.
„Magnetic fields appear to play an essential role in making planets habitable, so I wanted to find out how Earth’s magnetic field compared to those of other potentially habitable planets,“ she said.
Ms McIntyre said Earth’s strong magnetic field had probably played an important role in protecting the atmosphere from the solar wind and keeping the planet wet and habitable.
„Venus and Mars have negligible magnetic fields and do not support life, while Earth’s magnetic field is relatively strong and does,“ she said.
Mars today is a chilly desert. But ancient landscapes reveal a times when water may have flowed freely. Scroll to see how the red planet has evolved
Current theories of the formation and evolution of the terrestrial planets do support an Earth scale magnetic dipole (magnetic field) on Venus for perhaps the first billion years or so after formation.
The long-term evolutionary history of Venus’ climate largely remains a mystery.
Anti-riot police officers tear-gassed the protesters, including the elderly and children participating in the march, according to local residents. The Office of the United Nations High Commissioner for Human Rights (OHCHR) denounced the police excessive use of force against the demonstrators. The commissioner’s office said authorities in the area should „respect the right to expression and (the) peaceful gathering of all, including those who reject the project.“
Adani demanded the names of all federal agency scientists reviewing its contentious groundwater plans so it could check if they were „anti-coal“ activists, emails obtained under freedom of information show.
The revelation has alarmed CSIRO staff representatives, who said it indicated Adani had „a deliberate strategy“ to pressure scientists by searching for personal information it could use to try to „discredit their work“.
Mexican President Andres Manuel Lopez Obrador cancelled a gold mine project called Los Cardones in Baja California province on Sunday. The mine, located at one of the main aquifers of the southern area of Baja California, was a threat to the local water sources, according to Lopez Obrador.
(24. September 2009) The man who led the mission, Dr Mylswamy Annadurai, told the Times today how pleased he was at the discovery, which significantly enhances India’s position in its space race with China.
„It’s very satisfying,“ he said. „This was one of the main objectives of Chandrayaan-1, to find evidence of water on the moon.“
The reports from the Indian mission were backed up by the findings of two other studies to be published in the journal Science on Friday, showing that the water may be actively moving around, forming and reforming as particles mixed up in the dust on the surface of the moon.
(21.8.2018) As that statement indicates, scientists already knew that the lunar underground isn’t bone-dry. For example, in 2009, an impactor released by NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) blasted a bunch of water into space after slamming into a permanently shadowed region of Cabeus Crater, which lies near the moon’s south pole.
But it wasn’t clear from the LCROSS data where, exactly, that excavated ice originally lay — how much gray dirt once sat atop it. And, while several instruments have spotted tantalizing hints of exposed lunar ice over the years, these detections had remained unconfirmed until now.
Iran and Turkey have agreed to create joint committees for water affair and other related cooperation on power resources.
Iran’s Energy Minister Reza Ardakanian held a meeting with Turkey’s Minister of Agriculture and Forestry Bekir Pakdemirli in Ankara, Trend reports citing ILNA.
The ‘Our Water, Our Right Coalition,’ a civil society-led advocacy, has commended the 23 members of the Congressional Black Caucus (CBC) and Congressional Progressive Caucus (CPC) who wrote a letter of solidarity siding with Lagos citizens in their struggle against water privatisation.
„Baltimore will be a public water hero when this legislation passes—and should act as an example for other cities.“
