Light At The End Of The Road : The Bright Light At The End Of This Country Road Is Actually A Remarkably

Thirty years ago today, at 11:38 a.m. EST, January 28, 1986, the space shuttle Challenger lifts off from Cape Canaveral, Florida. Christa McAuliffe, teacher from New Hampshire, was to be the first ordinary U.S. civilian to travel into space. Challenger‘s launch countdown was repeatedly delayed because of weather and technical problems. Finally, on January 28, the shuttle lifted off.

73 seconds later, hundreds on the ground, including Christa’s family, stared in disbelief as the shuttle exploded in a forking plume of smoke and fire, killing all seven crew members. Millions more watched the heart-wrenching tragedy unfold on live television.

“The future doesn’t belong to the faint-hearted. It belongs to the brave.” President Reagan said. “The Challenger crew was pulling us into the future, and we’ll continue to follow. Nothing ends here; our hopes and our journeys continue.”

Rosetta: Alarm to sound for comet mission

One of the most daring space missions ever undertaken reaches a key milestone on Monday.

Europe’s Rosetta probe was launched a decade ago on a long quest to chase down and land on a comet, and has spent the past two-and-half-years in hibernation to try to conserve power.

But at 10:00 GMT, an onboard “alarm clock” is expected to rouse the spacecraft from its slumber.

QSL cards confirm either a two-way radiocommunication between two amateur radio stations or a one-way reception of a signal from an AM radio, FM radio, television or shortwave broadcasting station. They can also confirm the reception of a two-way radiocommunication by a third party listener. A typical QSL card is the same size and made from the same material as a typical postcard, and most are sent through the mail as such.

Cometary Globules

This morning, an Atlas V rocket launched from Cape Canaveral, Florida, carrying a US Navy communications satellite into space. 

It was another smooth take off for the United Launch Alliance, the company that manufactures the Atlas V. It was a particularly beautiful launch as well; the rocket left a spectacular multi-colored trail in its wake as it ascended into space

Comet lander Philae wakes up: How it happened and what’s next

By Lauren Raab

Philae, the first spacecraft to land on a comet, surprised and delighted scientists this weekend by waking up and reestablishing contact with Earth, seven months after running out of power. It “spoke” for more than a minute, according to the European Space Agency, and it’s expected to be able to continue gathering information and sending it home.

Here’s a look at what the lander has done so far and what will happen next.

Enceladus - Life in our solar system?

Enceladus is Saturns icy moon that measures approximately 504km in diameter, about a tenth of the size of Saturn’s largest moon Titan. Almost completely covered in ice, this moon could potentially harbour the same type of life-sustaining chemical reactions found in deep sea hydrothermal vents here on Earth.

In 2005, NASA’s Saturn orbiting Cassini spacecraft spotted geysers of water and ice erupting fro fissures near Enceladus’ South Pole. Scientists believe they originate from a great ocean beneath the shell of ice. This ocean manages to stay liquid because the gravitational force exerted by Saturn is so intense that it twists and stretches the moon generating internal heat.

In October 2015, Cassini went on a dive through one of the plumes passing within just 39km of Enceladus’ surface. A team of scientists led by Hunter Waite analysed the observations made by the spacecraft. They discovered that the geysers contain between 0.4%-1.4% molecular hydrogen (H2) and 0.3%-0.8% carbon dioxide (CO2). These are being produced continuously by reactions between hot water and rock near the core of the moon. Some of the most primitive metabolic pathways found in microbes at deep ocean hydrothermal vents involve the reduction of CO2 with H2 to form methane (CH4) by a process known as methanogenesis.
