Expedition 36 Soyuz landing – The Soyuz TMA-08M spacecraft with Expedition 36 Commander Pavel Vinogradov, Flight Engineer Alexander Misurkin and Flight Engineer Chris Cassidy (sitting far left) landed in a remote area of Kazakhstan on Sept. 11. They returned to Earth after five and a half months serving aboard the International Space Station. This article appeared …

Expedition 37 launch – The Soyuz TMA-10M rocket launched from the Baikonur Cosmodrome in Kazakhstan on Sept. 26, carrying Soyuz Commander Oleg Kotov, NASA Flight Engineer Michael Hopkins (left, middle) and Russian Flight Engineer Sergei Ryazansky to the ISS. Their Soyuz rocket launched at 2:58 a.m. local time. This article appeared in the 3rd issue of …

As NASA’s Curiosity rover begins her eighth month exploring the Red Planet since the nail-biting touchdown inside Gale Crater on Aug. 5, 2012, she has made the most amazing finding thus far. After analyzing the first powder ever drilled from the interior of a Martian rock, Curiosity discovered key chemical ingredients necessary for life to have thrived on early Mars billions of years ago.

Today, Opportunity celebrates a truly unfathomable achievement, entering Year 10 on Mars since she rolled to a bumpy stop on January 24, 2004. Now she’s at a super sweet spot for science loaded with clays and veined minerals and making the most remarkable findings yet about the planets watery past – building upon a long string of unthinkable discoveries due to her totally unforeseen longevity.

April 12, 1981: Space Shuttle Columbia launched this day from the LC-39A pad at Kennedy Space Center in Florida. The STS-1 mission lasted just two days, circling the Earth 37 times, before landing at Edwards Air Force Base in California. Columbia carried a crew of two – mission commander John W. Young and pilot Robert …

Starting with the Sojourner rover, launched in 1996, NASA has sent four robotic rovers to the Red Planet. On November 26, 2011, NASA launched Curiosity, its most technologically advanced rover ever. At a glance, it’s easy to see the size evolution between NASA’s youngest and oldest rover, but how else have they evolved? This chart …

NASA is challenging school-children to protect their future ride into space. The agency’s Exploration Design Challenge (EDC), announced March 11 during an event at the Johnson Space Center in Houston, engages U.S. students in kindergarten through high school in helping to solve the known problem of increased radiation exposure encountered on flights into deep space. …

Stargazing to discover secrets of the Milky Way Dr. Felix James (Jay) Lockman has spent the past two decades probing the origin of the Milky Way. He conducts his research from a rural area in West Virginia, a special place for radio astronomy that is unmatched anywhere else in the United States, using the Green …

A telescope is a spectacular scientific instrument that is accessible to people of all means and abilities and opens up the wonders of the Universe. Like all things technical it is a tool and you will only be able to use it with the correct training. Also, typically, there are a number of different types …

The constellation Orion is an easily recognisable star grouping visible in the northern hemisphere in even the most light polluted skies. Orion is depicted in amy ways: as a hunter wielding a club and shield, brandishing a sword and shield, or clubbing a lion. These however are just visualisations interpreting a pattern in the stars. …

I had an eagle-eye view as the Falcon 9 rose up from its launchpad, with Dragon leading the way through the cloud covered sky. It’s sound punched through the wind, letting out a low intense rumble as it headed for orbit, getting louder and louder with each second that passed. As the rocket rose higher, its sound started to fade, until it completely disappeared. The Falcon 9 had performed its job – and it was time for Dragon to commence its part of the mission. Soon it would meet up with the ISS for the delivery of supplies and experiments to the crew.

The International Space Station may look large in this picture, but it has come from humble beginnings. The very first module named Zayra was launched by the Russian Space Agency (Roscosmos), from the Baikonur Cosmodrome aboard a Russian Proton rocket in 1998. Following the placement of the first module in orbit, NASA launched the American …

Neil Armstrong wasn’t the only person who took a giant leap in space. Over the course of the last several decades, humanity has reached further into space than ever before. But one of our most astonishing achievements is actually just over our heads – the International Space Station (ISS). The ISS is an unprecedented partnership …

America’s first space station, Skylab was launched into orbit on a Saturn V rocket in May of 1973. Three manned missions to the outpost were immensely successful. Repairs made to the orbital station during several spacewalks ultimately proved that it was possible for astronauts to conduct work in outer space, which gave NASA the confidence …

The launch of any new spacecraft cannot be regarded as ‘routine’; nor, indeed, can its inaugural checkout in orbit. The Skylab orbital workshop was an entirely new concept for the United States and a totally different spacecraft, larger, more spacious and in many ways far more complex, than any that had gone before. Shortly after launch, telemetry data indicated a premature deployment of the protective micrometeoroid shield and the No. 2 workshop solar array. The very future of the space station was hanging by a thread.

An overview of each Skylab mission, from launch of the orbiting space station through the once planned Space Shuttle rescue mission.

The 920th Rescue Wing, based out of Patrick Air Force Base, serves as an Air Force Reserve Command combat-search-and-rescue unit. They are responsible for a variety of demanding missions and ready to deploy at a moments notice, trained to perform some of the most highly specialized operations in the Air Force. They’ve been the primary rescue force serving as “guardians of the astronauts” for 50 years, providing contingency response for a variety of emergencies that could potentially come up during a Space Shuttle launch or landing. These airmen and their elite team of Pararescuemen, known as PJ’s, are among the most highly trained emergency trauma specialists in the U.S. military, capable of performing life-saving missions anywhere in the world, at any time.

Human exploration of space began more than a half century ago with the launch of Vostok 1 on April 12, 1961. The small capsule carried cosmonaut Yuri Gagarin, the first human to leave to bonds of Earth and enter space. Exactly 20 years later, the United States began a new era in spaceflight with the inaugural launch of the Space Shuttle. 20 years after that, an annual celebration of our exploration of space began by connecting thousands of people around the world to celebrate past accomplishments and to inspire a new generation. That event is Yuri’s Night. Every year on April 12, Yuri’s Night brings the excitement and promise of space travel closer to people of all ages and all nationalities.

On April 12, 1961, Yuri Gagarin became the first man in space. His mission lasted 108 minutes and he made one orbit around the globe. Upon his return to Earth, he was lauded as a hero and the Soviet Union enjoyed its continued position as the leading power in space. But in the years and …

Student to attend, share experience of Soyuz launch Abby Harrison recently received an invitation almost as rare as winning the Powerball lottery. ESA Astronaut Luca Parmitano has invited her as his guest to attend the Russian Soyuz-TMA-09M Launch to the ISS on May 28. Harrison has long been a fan of space exploration and STEM …
