We guarantee you’ll go out of your Vulcan mind watching this new car commercial starring Spock … and Spock.
The Audi ad shows Leonard Nimoy (Spock from Star Trek‘s original series) and Zachary Quinto (Spock from Star Trek: Into Darkness, which premieres May 17) looking for new challenges after Nimoy wins a chess match.
“You want to play a round of golf in the club and get some lunch? Whoever gets to the club last buys lunch,” Quinto says to his predecessor.
“Stand by to have your wallet emptied by a tractor beam,” responds Nimoy.
Buzz Aldrin, celebrated Apollo astronaut and an outspoken champion for the pursuit of space exploration, is on a mission. He has written a new book titled “Mission to Mars.” While the title focuses on Mars, the book covers much more. Buzz lays out his goals for the space program and how he believes we can get humans to Mars by the 2030s. He makes the case and argues passionately for pushing our boundaries of knowledge and exploration of our solar system and presents his “unified space vision.” He emphasizes space exploration should not be a competition, but with cooperation a stronger path to a sustainable future in space could be forged.

A few of the many trees felled by the 1908 Tunguska explosion, photographed in 1929 (Wikipedia Commons)
Last week, Russian researcher Andrei Zlobin announced that stony fragments collected from a riverbed in 1988 are “probably Tunguska meteorites,” and are likely the remains of whatever cosmic object — thought to be either a comet or an asteroid — entered Earth’s atmosphere over the boggy region of Siberia on June 30, 1908, detonating with an estimated force of 5 megatons and leveling over 800 square miles of forest.
So far, definitive pieces of the original object have yet to be found despite numerous expeditions to the remote impact site. In a paper submitted on April 29, Zlobin cites the melted appearance of several stones found at the bottom of the Khushmo River as a good argument to “confirm the discovery” of Tunguska meteorite fragments.
According to Natalya Artemyeva of the Russian Academy of Sciences’ Geosphere Dynamics Institute, however, Zlobin’s claim is “ridiculous.”
In an article published May 4 on RIA Novosti, Artemyeva stated “There are many meteorites on Earth. For 100 plus years since the fall of the Tunguska space body, the weight of meteoric dust and small meteorites that have fallen out in that region has exceeded the mass of Tunguska.”

An estimated 100 tons of space debris enters Earth’s atmosphere on a daily basis.
Although Zlobin admits in his submitted paper that “strict confirmation of discovered melted stones as Tunguska meteorites is possible only after attentive chemical analysis of substance,” it seems that he is making rather bold claims based on appearance alone — especially considering the enigmatic and iconic nature of this particular impact event.
“It’s ridiculous,” Artemyeva said. “You can’t say by the appearance of a stone that it’s a meteorite. I don’t think there is ground for scientific discussion here.”
And, according to Artemyeva, even if the stones are found to be actual meteorites, connecting them to the 1908 event will still be a challenge.
Zlobin’s samples, which were in storage until 2008, are still awaiting full chemical analysis.

Buzz Aldrin, celebrated Apollo astronaut and an outspoken champion for the pursuit of space exploration has written a new book titled “Mission to Mars.” While the title focuses on Mars, the book covers much more. Aldrin says that while Mars is the destination, getting there is a journey that includes taking advantage of the efforts from commercial space companies, embracing space tourism, working towards planetary defense, developing technology, promoting STEM (science, technology, engineering and mathematics) education, and working together with international partners. What Aldrin calls his “unified vision” could provide a timeline of crewed missions to Mars is between 2035-2040.
“His point is trying to unify all of this,” said noted journalist and long-time Space.com writer Leonard David in an email to Universe Today. David is a co-author with Aldrin on this new book. “I hope the book is a good platform for moving the space exploration agenda forward.”
“Mission to Mars” is written from Aldrin’s perspective, and Aldrin and David spend little time looking back at the past achievements of Gemini and Apollo, and instead look forward of how the next steps in space exploration should be taken.
Universe Today had the chance to talk with Buzz Aldrin about his book and his plan. Following is part 1 of our interview:
Universe Today: Mr. Aldrin, it is an honor to talk with you – and congratulations on publishing another book. We really enjoyed getting the chance to read it and get your perspective on the future of space exploration.
Buzz Aldrin: Thank you very much. As far as the title, I really wanted to change the title to add an “s” to mission, as after thinking about it, it is the same title as Mike Collins’ book he wrote after we came back from the Moon, and it’s also the title of a not-so-successful movie! In this book, we also talk about much more than just one mission to Mars. We want many missions there, with a future-focused space exploration program.
Universe Today: Ever since you walked on the Moon, I think that Mars has been the ultimate destination that we’ve all dreamed about, and back in 1969, I think many people thought that by 2013, we certainly would have humans on Mars by this time. What do you think has been the biggest reason or roadblock that we’ve yet to achieve that goal?
Buzz Aldrin: There are probably a number of reasons. With Apollo, once having achieved the goal in a relatively intense parade of achievements, leading up to the crescendo of landing on the Moon six out of seven times, then it all ended. The events in the future are going to require much longer commitments to a pathway and a unified vision of what we should be doing and where we should go in space. I have always felt Mars should be the next destination following our landings on the Moon, but a unified vision is what we need to be able to increase the probability of being successful.
We are in a world that focuses on short term returns, and the politics these days is controlled by the desire to have an extraordinary portion of influence and control over the direction of the space program. That is probably one of the most important reasons for my embarking on a creating a foundation for the evolution of space policy, using what we’ve learned from the past to redirect some of our policies in the future for two things: the expansion of humans outward into the solar system and specifically for the US, global leadership in space as long as possible.
UT: You’ve long proposed the cycling system of having spacecraft almost on a railroad or bus lines of going regularly back and forth to Mars. Can you explain for our readers why this is the most efficient way of getting supplies and people to Mars?
Buzz Aldrin: When a spacecraft departs Earth, the main portion of it is rarely ever re-used. This one spacecraft contributes its one mission, as we did with the Apollo spacecraft. Now, if we can depart a spacecraft from the Earth that can carry some of the mass, in particular the radiation protection and other supplies for a brief 5-6 month trajectory of swinging past Mars, we can reduce costs.
Years ago I devised a method with cycling orbits of spacecraft on continuous trajectories between the Earth and Mars – a spacecraft going to Mars and then returning back to Earth at just the right time, angle and velocity to be able to repeat the process 26 months later when Earth, again, is in a favorable position. By using interplanetary cyclers, I feel, and other space experts agree with me, this is the most economical transportation system concept between the Earth and Mars.
When I first discovered this, it was studied and understood by the 1986 Paine Commission, a group who looked at pioneering space, led by the administrator of NASA who had directed us in our lunar landings, Tom Paine. This was, I think, one of the best and most complete studies ever really done.

But since this Commission’s reference to cycling spacecraft, NASA officials and space companies have paid little attention to the advantages of cycling orbits — with the exception of the University of Purdue, which works with engineers at JPL and Caltech — and together with my pioneering ideas, we have discovered that if there are two cycling spacecraft, it gives us a bigger advantage and reduction in the fuel needed. In each cycle, the Cycler’s trajectory swings it by the Earth, and a smaller Earth-departing interceptor spacecraft ferries crew and cargo up to dock with the Cycler spacecraft, and likewise at Mars to reach the surface. So we’ve improved the cycling orbit potential. We now need to test the long-duration equipment that will be needed. Ultimately, this Cycler system of transportation offers a way to make travel to Mars sustainable for the long-term.
For the spacecraft, what I’ve done is taken my concept, which is based on some of NASA’s work of an interplanetary vehicle and put of them together side by side for redundancy, and perhaps adding a few other necessary elements, to become the Cycling spaceship. I also propose building a permanent base on the surface of Mars by actually landing on the moon of Mars Phobos, and building it tele-robotically from there, with various objects such as inflatable habitats, to be assembled into a Mars base. These missions should be international in nature.
All of this is very complex and we need to learn how to build up to it. But one of the most attractive ways would be, before finalizing the Mars base, we could execute an international lunar base. This could be based upon US leadership of what could be an international lunar development authority — much like Intelsat was developed for international satellite communications in geosynchronous orbit. We also have the International Space Station to do some of the initial testing of equipment, such as long duration life support systems.
Not only does NASA need this long-duration life support but also the recently announced Inspiration Mars Mission, which would send a married couple in January 2018 on a flyby of Mars. This would do much to stimulate the planning and testing of the progressive development of the interplanetary space capabilities.
Before we execute an international partner mission back to the Moon, we can test that assembly process on the Big Island of Hawaii where people have been working to select a site similar to where we might have a lunar base built and there we could practice building a base tele-robotically. Once on the Moon, we could develop lunar infrastructure, and allow for robotic mining that could be done for commercial development.
We’ll need cooperative activities between the government, NASA, other government agencies and the commercial companies executing their activities designed to evolve into profit-making businesses.
UT: You mention in your book that a space race with China would be counterproductive. Do you think there’s a way to work with them and have it be productive and beneficial beyond space exploration?
Buzz Aldrin: Right now, unfortunately, Congress forbids NASA personnel to even talk with China. The great opportunity of bringing China into the ISS, is that we could still do this during the lifetime of the space station. China is developing its own its space station, but there doesn’t seem to be an openness between our two countries to work on the big picture of space exploration. Everyone is out for their own return. But there could be a wonderful opportunity here for the US to exercise global leadership in space activities.
Tomorrow: Part 2 of our interview with Buzz Aldrin, where he discusses his thoughts on NASA’s asteroid-lassoing plans, space elevators, and future commercial mission.

It’s a simple menu, but smoking hot. The black hole at the center of the Milky Way galaxy is sucking in ultra-hot molecular gas, as seen through the eyes of the Herschel space telescope.
“The biggest surprise was quite how hot the molecular gas in the innermost central region of the galaxy gets. At least some of it is around 1000ºC [1832º F], much hotter than typical interstellar clouds, which are usually only a few tens of degrees above the –273ºC [-460ºF] of absolute zero,” stated the European Space Agency.
Herschel, which is out of coolant and winding down its scientific operations, will continue producing results in the next few years as scientists crunch the results. The telescope has found a bunch of basic molecules in the Milky Way that include water vapour and carbon monoxide, and has been engaged in looking to learn more about the gas that surrounds the massive black hole at our galaxy’s center.
In a region called Sagittarius* (Sgr A*), this huge black hole — four million times the mass of the sun — is thankfully a safe distance from Earth. It’s 26,000 light years away from the solar system.

Trouble is, there’s a heckuva lot of dust blocking our view to the center of the galaxy. Herschel got around that problem by taking pictures in the far-infrared, seeking heat signatures that can bely intense activity in and around the black hole.
“Herschel has resolved the far-infrared emission within just 1 light-year of the black hole, making it possible for the first time at these wavelengths to separate emission due to the central cavity from that of the surrounding dense molecular disc,” stated Javier Goicoechea of the Centro de Astrobiología, Spain, lead author of a paper reporting the results.
The science team supposes that there are strong shocks within the gas (which is magnetized) that help turn up the heat. The shocks could occur when gas clouds butt up against each other, or material shoots out Fast and Furious-style between stars and protostars (young stars.)
“The observations are also consistent with streamers of hot gas speeding towards Sgr A*, falling towards the very center of the galaxy,” stated Goicoechea. “Our galaxy’s black hole may be cooking its dinner right in front of Herschel’s eyes.”

How fast is Greenland’s ice sheet melting in response to climate change, and how is it recovering? A new NASA rover with the friendly name of GROVER (Greeland Rover and Goddard Remotely Operated Vehicle for Exploration and Research) is going to try to figure that out.
GROVER will rove across a small area of the massive ice sheet at a location called Summit Camp, which is a National Science Foundation outpost. On board it has ground-penetrating radar that is intended to figure out how the snow builds up in layers through time.
“Robots like GROVER will give us a new tool for glaciology studies,” stated Lora Koenig, a glaciologist at Goddard and science advisor on the project.

The student-designed project came to be during development phases in 2010 and 2011, principally at Boise State University in Idaho. At six feet tall, it’s way more massive than its Sesame Street namesake: it tips the scale at 800 pounds, including solar panels, and has two snowmobile tracks built in to move around.
“GROVER is just like a spacecraft but it has to operate on the ground,” stated Michael Comberiate, a retired NASA engineer and manager of Goddard’s Engineering Boot Camp.
“It has to survive unattended for months in a hostile environment, with just a few commands to interrogate it and find out its status and give it some directions for how to accommodate situations it finds itself in.”
Studies began on May 3 and will continue through June 8.

The second flight of ESA’s newest launch vehicle has successfully sent three different satellites to space. Launching at 02:06 GMT on 7 May from Europe’s Spaceport in Kourou, French Guiana, the Vega rocket carried two Earth observation satellites — ESA’s Proba-V, Vietnam’s VNREDSat-1A — and Estonia’s first satellite, the ESTCube-1 technology demonstrator were released into different orbits. The complex mission required five upper-stage boosts, with the flight lasting about twice as long as its first launch, in February 2012.
ESA officials said the success demonstrates the Vega rocket’s versatility.
Watch the launch video below.
“It is another great day for ESA, for its Member States and for Europe,” said Jean-Jacques Dordain, Director General of ESA. “Thanks to decisions taken by Member States, ESA and European industry are demonstrating once again their capabilities of innovation. Among the Member States, special mention goes to Italy which has led the Vega Programme, Belgium which has led the Proba projects at ESA, and France which has led the development and maintenance of the European spaceport here in Kourou. We are also proud to have made possible the launch of the first satellite from Estonia.”
The three solid-propellant stages performed flawlessly and after two burns of the liquid-propellant upper stage, the Proba?V was released into a circular orbit at an altitude of 820 km, over the western coast of Australia, some 55 minutes into flight.
After releasing Proba-V, the upper stage performed a third burn and the top half of the egg-shaped Vega Secondary Payload Adapter was ejected. After a fourth burn to circularize the orbit at an altitude of 704 km, VNREDSat-1A was released 1 hour 57 minutes into flight. ESTCube?1 was ejected from its dispenser three minutes later.
The fifth and last burn put the spent upper stage on a trajectory that ensures a safe reentry that complies with new debris mitigation regulations.

This beautiful new timelapse video might have folks heading in droves for northern Michigan. Shawn Malone of Lake Superior Photo put together this incredible video — her first attempt at a timelapse compilation, believe it or not — using over 10,000 photo frames showing 33 different scenes of various night sky events from northern Michigan over the past year. “It took a year to shoot and a bit of tenacity and persistence to get this into a form of coherent electrified cosmic goodness,” Malone wrote on Vimeo. And did she ever capture cosmic goodness: auroras, the Milky Way rising and setting, meteor showers, a comet, and even aurora and lightning together in one scene. Just gorgeous….
