Big news: Astronomers have discovered that the nearest star to the Earth, Alpha Centauri, has an exoplanet only slightly heavier than the Earth.

Alpha Centauri is actually a triple star system, with two sunlike stars in a tight orbit around each other and a third star far out orbiting them both. The exoplanet orbits one of the inner stars every 3.2 days.

More details from Nature here.

Faced with stiff competition in the launch market, Europe struggles to come up with a competitive replacement for Ariane 5

Faced with stiff competition in the launch market, Europe struggles to come up with a competitive replacement for Ariane 5

“I strongly believe we have to decide, as quickly as possible, to develop a new-generation launcher to be competitive in the market as it is forecast, and with the competitors,” [ESA Director General Jean-Jacques] Dordain said at the Berlin air show last month, a reference to new launch vehicle developments in India, China and the U.S., where Space Exploration Technologies’ low-cost Falcon 9 is challenging the global launcher market.

While space cadets might argue about launch prices till the cows come home, the actual competitors in the industry know better: SpaceX’s low prices are real and are forcing everyone to find ways to lower costs or lose business.

The Cuban government announced today that it will allow its citizens to freely visit other countries for the first time in over a half century.

The Cuban government announced today that, beginning January 13, 2013, it will allow its citizens to freely visit other countries for the first time in over a half century.

This quiet announcement reminds me of what happened in East Germany in 1991. The government then made a quiet announcement saying it would allow travel outside its country, and within days the Berlin Wall was literally being torn down by its citizens. Shortly thereafter East Germany ceased to exist, absorbed into Germany itself, and the communist bloc fell apart.

Hopefully, we shall see the same thing happen to the Cuban dictatorship.

Just two months after the failure of its second stage during launch, Russia’s Proton rocket successfully put a communications satellite into orbit yesterday.

The competition heats up: Just two months after the failure of its second stage during launch, Russia’s Proton rocket successfully put a communications satellite into orbit yesterday.

This quote, from this Space News article, also implies that there is increasing competitive pressure in the launch industry, which I attribute to the success of SpaceX’s Falcon 9:

Perhaps the most striking element of the launch is that Washington- and Luxembourg-based Intelsat agreed to proceed with it so soon after the August failure of the Proton Breeze-M upper stage. It has been common practice following previous Proton failures that a Russian government mission would be the customer on the return to flight. In this case, Intelsat and its insurance underwriters were sufficiently persuaded that Reston, Va.-based ILS and Proton prime contractor Khrunichev Space Center of Moscow had come to grips with the issue to agree to be the customer for the first flight after the failure.

Scientists have found the source of the water on the Moon and Mercury: the solar wind.

Scientists have found the source of the water on the Moon and Mercury: the solar wind. Key paragraph:

“We found that the ‘water’ component, the hydroxyl, in the lunar regolith is mostly from solar wind implantation of protons, which locally combined with oxygen to form hydroxyls that moved into the interior of glasses by impact melting,” said Zhang, the James R. O’Neil Collegiate Professor of Geological Sciences. “Lunar regolith is everywhere on the lunar surface, and glasses make up about half of lunar regolith. So our work shows that the ‘water’ component, the hydroxyl, is widespread in lunar materials, although not in the form of ice or liquid water that can easily be used in a future manned lunar base.” [emphasis mine]

Though this result would explain the detection of hydrogen on the lunar surface and would also mean that this hydrogen is far less useful for future colonists than previously hoped, it doesn’t eliminate the possibility that there is ice in the permanently shadowed craters near the lunar poles that came from other as yet unknown sources.

It now appears to be illegal to drive around in Dearborn, Michigan displaying Israeli flags on your vehicle.

The tolerance of Islam: It now appears to be illegal to drive around in Dearborn, Michigan displaying Israeli flags on your vehicle.

The [driver] involved was driving in front of the high school as it let out. He was backed up in traffic, a police car immediately behind him. He had Israeli flags on truck. When the students began their assault he rolled down his window asking them to stop. After they pulled him over the police used the rolled down window as a pretext to accuse him of instigating the altercation. While being questioned by the police in front of the high school the [driver] received death threats. The police denied hearing them though the individuals involved were only a few feet away.

The assault also included one high school student throwing a bottle at the car.

Damn, I wish I lived close to Dearborn. I would be organizing a large parade of cars with Israeli flags right this minute.
