Well this is interesting: an article on CNET by Eric Mack, based on a Nov. 27 report from the Russian news agency TASS, discusses findings by Russian cosmonaut Anton Shkaplerov that “living bacteria from outer space” were found within samples collected during spacewalks several years ago (Shkaplerov was a member of Expedition 42 in November 2014.)
The samples were swabbed from outside surfaces of the International Space Station, including areas where engine fuel waste is expelled, and brought back to Earth for study. In addition to some terrestrial bacteria that were accidentally brought to the ISS via contaminated computer tablets, there were also living organisms found that “were absent during the launch of the ISS module.”
“That is, they have come from outer space and settled along the external surface,” Shkaplerov stated. “They are being studied so far and it seems that they pose no danger.”
In its long history of space exploration the United States has never had a robotic mission sent to the surface of Venus. Flybys, orbiting spacecraft, and atmospheric probes yes, but to date nothing from NASA has operated on the extreme, hellish surface of the second rock from the Sun. Russia, on the other hand, has successfully landed on Venus ten times, eight with its Venera program and the ninth and tenth in 1984–85 with the Vega 1 and 2 missions. Because of its long-running expertise, the U.S. is looking to partner with Russia on a brand-new Venera mission, Venera-D, which in 2025 would send an orbiter, a lander, and possibly even an inflatable airship to Venus to explore its exotic and overheated environments.
“While Venus is known as our ‘sister planet,’ we have much to learn, including whether it may have once had oceans and harbored life,” said Jim Green, NASA’s director of Planetary Science. “By understanding the processes at work at Venus and Mars, we will have a more complete picture about how terrestrial planets evolve over time and obtain insight into the Earth’s past, present and future.”

Four years ago today an explosion shattered the morning sky over the Chelyabinsk region in southwestern Russia, the result of a 60-foot-wide fragment of an asteroid entering Earth’s atmosphere at over 40,000 mph and brilliantly blowing itself to smithereens at 97,000 feet up. Even at that altitude, the resulting flash of light and air blast was powerful enough to cause extensive damage on the ground, shattering windows, knocking in doors, and causing injury to nearly 1,500 people across towns in the area—several of them seriously.
This was the largest observed meteor since the famous 1908 Tunguska event, but thanks to the prevalence today of dashboard and CCTV cameras in Russia this one was well-recorded. (I remember seeing the videos online within an hour after it happened!) The footage has allowed scientists to not only determine the energy of the Chelyabinsk meteor explosion—about 500 kilotons—but also the object’s trajectory and origin.
Watch a video below of footage captured from various locations of the Chelyabinsk meteor:
This is an article, now updated, that I originally posted in 2009 during my first year of blogging. Since then more research has been done on the famous 1908 Tunguska Event and we even had a remarkably similar type of thing occur in February 2013 over the Chelyabinsk area, not too far from Tunguska, but even today, the 108th anniversary of the event, scientists aren’t in agreement over what it was that violently exploded over the boggy forests of Siberia—asteroid or comet.
Long the subject of debate, with various theories ranging from meteorite impact to a comet to a flying saucer’s sudden engine meltdown, there’s actually strong evidence that the 1908 “Tunguska Event” was likely caused by the explosion of a comet in the upper atmosphere.
This idea has been suggested before, and is supported by Cornell University engineering professor Michael Kelly’s study of – strangely enough – the space shuttle’s exhaust plumes and their effect on high-atmosphere cloud formation.
To those not familiar with the Tunguska Event, something exploded or impacted in the remote area of Russia on June 30, 1908, flattening the forest in an 830-square-mile area, but leaving no visible crater or other obvious sign of what caused the event. Nearby residents reported the sound of a massive explosion, but that’s about it. Whatever it was, the devastation it caused was extensive and undeniable.
The International Space Station is the result of an amazing collaboration of many countries and countless individuals from around the world, a research lab and symbol of global peace and partnership put together in space. But recent and growing political tension between the two biggest contributors to the ISS – the United States and Russia – are casting doubt on the status of Station’s future. Will Russia continue its support of the ISS? Or will they build their own space station like some reports have suggested? And if so, what will happen to the current Station?
Ron Garan, former NASA astronaut and ISS crew member, humanitarian, and author of the new book The Orbital Perspective, is featured in a webcomic by Andy Warner (perhaps in honor of Free Comic Book Day?) called “Atmospheric Breakup,” which addresses the significance of the ISS and the challenges facing its future.

By continuing to spread the word about the importance of international collaboration, Ron is showing us that real superheroes wear blue flight suits!
