Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.
Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.
The Spaceflight101 portal said the delay was due to possible “mold and bacteria contamination on three cargo bags that are inside the spacecraft” and that a decision is yet to be made on whether the crew should use anti-mold kits to clean ATV-4 cargo before taking it inside the ISS.
The Russians had a lot of problems with mold in their early Salyut space stations, and understand the unpleasant consequences should mold spread into the station. Thus, I am not surprised if they are taking this issue seriously.
After six years of study, Venus Express has found that during that time the super-rotating winds of Venus have actually increased in speed.
After six years of study, Venus Express has found that during that time the super-rotating winds of Venus have actually increased in speed.
When Venus Express arrived at the planet in 2006, average cloud-top wind speeds between latitudes 50º on either side of the equator were clocked at roughly 300 km/h [186 mph]. The results of two separate studies have revealed that these already remarkably rapid winds are becoming even faster, increasing to 400 km/h [250 mph] over the course of the mission.
Engineers have decided to keep the New Horizons spacecraft on its original fly-by path past Pluto, scheduled for July 2015.
Engineers have decided to keep the New Horizons spacecraft on its original fly-by path past Pluto, scheduled for July 2015.
The New Horizons team recently completed an 18-month study of potential impact hazards – mostly dust created by objects hitting Pluto’s small satellites – the spacecraft would face as it speeds some 30,000 miles per hour (more than 48,000 kilometers per hour) past Pluto in July 2015. The team estimated that the probability of a mission-ending dust impact was less than 0.3 percent if the spacecraft followed the current baseline plan, far below some early, more conservative estimates. So, with the concurrence of an independent review panel and NASA, the project team expects to keep New Horizons on this baseline course, which includes a close approach of about 12,500 kilometers (nearly 7,800 miles) from the surface of Pluto.
The count of candidate exoplanets found by Kepler has now risen another 503 to 3,216, of which only 132 have been confirmed.

These new exoplanets were found before the telescope failed but the data for them is only now being released.
Engineers in the Czech Republic have built a bicycle that can fly.
Engineers in the Czech Republic have built a bicycle that can fly.
The demonstration does beg the question “Why a bike?”. Once those big, knobby tires are lifted off the ground, aren’t they rendered more or less moot? According to the project website, the central concept was to create a flying vehicle that could easily be ridden to a more suitable takeoff site and then be capable of a 3 – 5 minute flight. In order to offset the extra weight added by all the rotors, they could be used to help propel the bike along the ground, besides allowing it to fly.

The sad state of science: “Self-confessed liar publishes more dubious stem-cell work.”
That’s an actual Nature headline. Worse, the publication that published the new papers — which were plagiarized from already retracted papers — is peer-reviewed, which illustrates how seriously they take that review process — not!
Close-minded politicians everywhere!
Despite the repeated news in recent weeks that the evidence for global warming is slim, or at least confused, today we have two elected officials and one appointed official screaming that the sky will fall if we don’t do something, including spending billions of dollars of other people’s money.
First we have our friend Al Gore, who was in Washington, DC to speak at an environmental event put on by Senator Sheldon Whitehouse (D-Rhode Island). Whitehouse you might remember was the senator who, even before the injured and dead had been counted from the terrible Moore, Oklahoma tornado, started blaming Republicans for the tornado because they weren’t doing more to stop global warming.

“Now I dream of snowboarding down a Martian sand dune on a block of dry ice.”
Despite the decline in Arctic sea ice during the past decade the population of polar bears in the Davis Strait has skyrocketed.
Despite the decline in Arctic sea ice during the past decade the population of polar bears in the Davis Strait has skyrocketed.
The increase might have even placed the population at the carrying capacity for the region.
In related news, the New York Times has finally admitted to the fact that the climate stopped warming fifteen years ago.
At the same time, the reporter has a great deal of trouble dealing with this fact, mainly because he refuses to recognize that the theories of carbon-dioxide-caused global warming might be mistaken.

Yup, it rains metal on Venus, producing mountain caps made of heavy metals.
