Friday's crater mission is the riskiest for Hayabusa2, as it had to immediately get away so it won't get hit by flying shards from the blast. "After the start of the operation, the camera (DCAM3) [that] separated from Hayabusa2 captured an image that shows ejection from Ryugu's surface, which implies that the SCI had functioned as planned", Japan Aerospace Exploration Agency (JAXA) officials wrote in an update this morning.

Responding to NASA administrator James Bridenstine's observations that the risk of collision with ISS had risen 44 per cent after India's ASAT test, Reddy said when India conducted the test, the space station was over French Guiana. On Tuesday, the NASA had termed India's shooting down of one its satellites as "terrible thing" and said the hit-to-kill mission created about 400 pieces of orbital debris. (more...)

A search party immediately sprung into action, although after an intensive search, only a skull and a pair of pants was found, with the rest of the poacher's remains believed to have been consumed by the lions . There's no evidence that rhino horn, made of the same substance as human fingernails, actually holds any medicinal value. They then fled the park and were arrested after a joint intelligence operation by police. (more...)

Unfortunately, scientists did not find the last part of the tail section of this creature, but the first vertebra connecting this section of the bones was similar to what modern-day beavers and otters have. "This would therefore have been an animal that would have started to make growing use of its tail to swim, which differentiates it from older cetaceans in India and Pakistan ". (more...)

Ms Moriarty said some coral species were doing well and were not bleaching at all, but some other species had 100 per cent bleaching in particular spots. "We used to think that the Great Barrier Reef was too big to fail - until now". "So you're not having fresh water come in, you're not having cloud cover and so forth", she said. (more...)
Manitoba to Challenge Carbon Tax in Court Manitoba to Challenge Carbon Tax in Court
- April 05, 2019

The premier confirmed that immediately after unveiling its Made-in-Manitoba Climate and Green Plan, and on multiple occasions after that, Manitoba sought the federal government's assurance that it would not impose its tax on Manitobans. "We would not need to do that but, at the same time, I don't want to prejudice the legitimacy of our court case by getting into hypotheticals". Todd MacKay, prairie director of the Canadian Taxpayers Federation, supports the court battle. (more...)
Over 1.2 Million Early Deaths in India Due to Air Pollution Over 1.2 Million Early Deaths in India Due to Air Pollution
- April 05, 2019

Long-term exposure to indoor and outdoor pollution contributed to almost 5 million deaths globally in 2017, with fatalities resulting from stroke, heart attack, diabetes, lung cancer and chronic lung disease, the analysis found. And while the quality of it has been poor over the years, India and China appear to be particularly susceptible to its disease burden, as is clearly visible in the relative pollution levels and disease burden in countries neighbouring India (see slider below).

About three weeks after smacking Ryugu with what's basically a copper cannon ball, Hayabusa2 will begin a search for the artificial crater from a higher vantage point and plan for a touchdown at its custom landing spot as early as May. JAXA says it has confirmed Hayabusa2 safely evacuated and remained intact after the blast. "So far, Hayabusa2 has done everything as planned, and we are delighted", mission leader Makoto Yoshikawa said earlier Friday. (more...)

That said, Bridenstine assured the town hall audience that the six people now on board the ISS aren't in any immediate danger. Initially, the orbit of the satellite was thought to be low enough that all the debris created from the blast would fall harmlessly back to Earth, where it would burn up completely upon re-entry.

ALP Climate Policy: Holding Our Heads A Little Higher ALP Climate Policy: Holding Our Heads A Little Higher
- April 05, 2019

The government has attacked this aspect, with Prime Minister Scott Morrison saying it would force Australian business to spend money on "carbon credits for Kazakhstan". This would lead to businesses being able to choose the most efficient and cost-effective manner to offset emissions, and would also let them sell their own credits if they cut pollution below their baseline, he said.

Rumors of 1st Ever Black Hole Photo Fanned by Scientists' 'Mysterious Meetings' Rumors of 1st Ever Black Hole Photo Fanned by Scientists' 'Mysterious Meetings'
- April 04, 2019

Even more confounding is that spacetime around a black hole is "weird". The specific black hole astronomers wanted to photograph, Sagittarius A* , lies at the center of our galaxy 25,000 light-years away. To be clear, the image here isn't the image that we will see next week. This has proved incredibly testing for scientists, due to dust and disruption surrounding black holes . (more...)
Scientists Find Likely Source of Methane on Mars
- April 03, 2019

In the 15 years since a European probe reported traces of the gas in the Martian atmosphere, a debate has raged over the accuracy of the readings showing methane, which on Earth is produced by simple lifeforms. If microbes still exist, they are one possible source. The scientists used the orbiter's planetary fourier spectrometer (PFS) to look for methane in and around Gale crater from December 2012 to July 2014. (more...)

However, the new wing can move the whole wing or just sections to give greater precision control over movement. The wing performed even better than expected in NASA's wind tunnel at Langley Research Center. In the near future, aircraft could look substantially different from what we are used to today, particularly when it comes to the shape of their wings. (more...)
