Concern about the supply chain for the ISS has been growing steeply over the last months. The final flight of Atlantis turned the ominous shadow of a future without the shuttle into a glum reality. And only a few weeks later, we have witnessed, with some degree of a shock, the first failure of a Progress mission in many years.

The first post-shuttle resupply mission in ISS history got off to a rocky start, as a Russian Progress cargo spacecraft failed to reach orbit, crashing into south central Russia.

This photo is making the rounds of Twitter, Facebook, Google+, and whatever other social network you care to name today. It was shot by astronaut Ron Garan from the Space Station, and it's a meteor seen from above. Way cool.

An update on human spaceflight, including orbital propellant depots, suborbital test flights and an Orion crew capsule test aboard a Delta IV Heavy.

Private spaceflight company SpaceX has secured tentative approval with NASA to combine its next test flight with an actual ISS docking.

At 5:57AM EDT (9:57 UTC) this morning, Atlantis gracefully rolled to a stop on runway 15 at the Kennedy Space Center Landing Facility, completing the 135th and final mission of the space shuttle program that started in 1981.

The final installment of my three-part series on the basics of shuttle launches and landings. Part III: de-orbiting, re-entering and landing.

Since jumping from the Boston Globe to the Atlantic with his signature galleries of striking images, Alan Taylor has continued to regularly feature space-themed photos. This week his In Focus feature looks back at the shuttle program with 61 images -- check it out!

After a 16 day journey of more than sixteen million miles, Space Shuttle Endeavour and her six man crew glided to a safe nighttime landing at 2:35 a.m. EDT on June 1 at NASA's Kennedy Space Center in Florida. I watched from close by the shuttle landing strip as the ghostly ship flew past, preceded by shocking twin sonic booms.

In the middle of the night on June 1, 2011, millions of passengers returned safely to Earth as part of the great conclusion to space shuttle Endeavour's last flight, STS-134. Many of those millions of passengers were part of the Planetary Society's Shuttle LIFE experiment. Five different kinds of creatures from all three domains of life are part of Shuttle LIFE.

Space exploration is an international endeavor and I usually try to speak as a citizen of Earth rather than one of my nation, state, or city, but I'm going to ask you to indulge me in a little local boosterism today.

On April 12, 1961, Yuri Gagarin became the first human to see firsthand the blackness of space above our home planet's thin atmosphere. Since there's lots of thoughtful reporting and commentary being posted on this anniversary, I thought it'd be more useful to link to some particularly interesting posts than to add in my comments.

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

The Planetary Society is contributing this thing called the Living Interplanetary Flight Experiment (LIFE) to Russia's Phobos sample return mission -- it's basically a sealed puck with dormant microbes inside that'll fly to Mars and back in the return capsule, and biologists will take a look to see what damage the little bugs suffered during their space journey.

In the past week there have been 25th anniversaries of two events in 1986, one great, one terrible: the closest approach of Voyager 2 to Uranus on January 24, and the explosion of the space shuttle Challenger upon liftoff on January 28.

The launch has been scrubbed once again due to a critical hydrogen leak detected once fueling had been underway for a while.

Discovery has suffered an electrical problem related to one of the main engines. Thanks to delays related to that, and to weather concerns, the launch was scrubbed until Friday at 3:04pm.

Mat Kaplan is at the Kennedy Space Center, 22 hours before shuttle Discovery is due to launch. Parts of the KSC are old and uncared for, while others are at the bleeding edge of space-flight technology.

A brief musing on the public opinion of the shuttle when it was first unveiled, and now, as it's about to be retired.
