NASA finds water ice just below the surface of Mars
- To explore the solar system beyond our planet, one important factor is the ability to locate water which can be used for drinking and for creating rocket fuel.
- To assist in the hunt for water on neighboring Mars, NASA has released a "treasure map" of potential ice locations on the red planet.
- Researchers created the map of the Martian surface which shows where water ice is believed to be located.
- Locating ice is important to enable manned missions to the planet, and could help identify sites for projects like SpaceX's planned Mars base.
- Scientists realized that looking below the Martian surface is the best hope of finding accessible water ice, and that there may even be liquid water beneath the polar ice caps.
- With this new map, researchers have a blueprint for where to start planning missions and eventually sending astronauts to Mars.
You Should Upgrade to Angular 9 TODAY
- For those of you who have short attention spans (like me), I hope that this summary is enough to give you some talking points and/or enough to start thinking about the benefits of upgrading to Angular 9 today.
- If you think your team may need some help from them, then TODAY is the time for you to upgrade.
- Additionally, thanks to the version control system used internally at Google, any time the Angular team releases a change to the framework, the tests of every project at Google that depends on Angular get executed.
- Because this is the point of the release, it makes it a great time for your team and your projects to get on board early and be a part of the v9 upgrade party that is happening right now (before the official v9 release).
ICE arrests dropped in the past year amid southern border crisis
- According to the agency, limited resources and the volume of people who entered the United States strained ICE's ability to arrest undocumented immigrants already living in the country.
- Customs and Border Protection, a separate enforcement agency within the Department of Homeland Security, apprehended and deemed inadmissible nearly 1 million people during the government's 2019 fiscal year.
- The increase of arrests along the southern border resulted in an uptick in the number of people in immigration detention.
- According to ICE, 63% of the people in their custody were initially arrested by CBP, not ICE, signaling the high number of migrants at the southern border.
- The operation, which was similar to one conducted under the Obama administration, was intended to target around 2,000 migrant families who had removal orders and appeared to be part of a concerted enforcement effort to target families and unaccompanied children.
Greenland lost almost 4 trillion tonnes of ice in less than 30 years
- That is roughly in line with the most extreme scenario of future ice losses set out in the 2014 Fifth Assessment Report by the Intergovernmental Panel on Climate Change.
- In that scenario, global sea level will rise by 52 to 98 centimetres by 2100, partly due to ice loss from Greenland.
- “The ice losses are tracking the upper scenario from the IPCC,” says Andrew Shepherd at the University of Leeds, UK.
- Shepherd and his colleagues combined 26 satellite data sets to reconstruct how the ice sheet has changed due to the warming climate.
- Since 1992, ice losses from Greenland have contributed 1.06 centimetres to sea level rise, according to the new analysis.
- Ice losses from other glaciers and from Antarctica, plus the expansion of seawater as it warms, combine to give a total rise of about 7.5 centimetres over roughly the same period.
Mars’ landslides defy the laws of physics — now scientists might know why
- The landslide shows long ridges that extend in the direction of the movement for almost the entire length of the deposit.
- As mentioned, these ridges have previously been interpreted to be a result of underlying ice at the time of the landslide.
- Based on this similarity, the presence of the ridges on martian landslides has been used in support of the theory that Mars was once covered in ice.
- Instead, we propose that the ridges could have formed at high speeds due to underlying layers of unstable, light rocks.
- Once we had accounted for this mechanical instability – and coupled it with the movement at phenomenal high speed of the slide – we could show that vortices extending in the direction of the landslide’s movement were generated, giving rise to the long ridges that we observe on the surface of the landslide.
'Missing link' penguin fossil shows how they evolved after dinosaurs went extinct
- Scientists have discovered fossils that act like the missing link for their evolution -- and it all happened after the dinosaurs went extinct.
- Fossils from five partial skeletons were found on the Chatham Islands near New Zealand's South Island.
- The fossils belong to the newly discovered species Kupoupou stilwelli, the oldest known penguin that's similar in size to modern penguins.
- Ancient penguin fossils have been found on South Island's eastern coast, which is 497 miles from the Chatham Islands.
- Earlier this year, fossils belonging to "monster penguin" Crossvallia waiparensis were found in Waipara, near the city of Christchurch on New Zealand's South Island.
- Recent discoveries have also uncovered other large creatures that lived in New Zealand, including the world's largest parrot, the large flightless moa bird, a giant eagle and a giant burrowing bat.
Pete Frates, one of the men who popularized the Ice Bucket Challenge, has died
- Pete Frates, 32, was one of the most recognizable faces of the ALS Ice Bucket Challenge, a viral sensation that swept the Internet in 2014 and raised more than $115 million for ALS research.
- In 2013 and 2014, Frates and two fellow Boston College alumni popularized what is now known as the ALS Ice Bucket Challenge, which involves dumping ice water on your head, making a donation to an ALS organization and challenging others to participate.
- The challenge raised $115 million during a two-month period in 2014, according to the ALS Association.
- They asked that anyone who wishes to extend an expression of sympathy donate to the Peter Frates Family Foundation, which aims to help ALS patients in the advanced stages of the disease stay at home.
