Noteworthy Quote: Leaving Humans on Other Planets

"These people have been trained and given the great historical value of being the first human beings in history to occupy another planet and people want to bring them back?...Let me ask those people who want to bring them back, what are you going to do with them back here on Earth that will in any way [justify] the billions and billions of dollars that have been invested in those human beings to put them on Mars?"

- Statement by former astronaut Buzz Aldrin discussing flying people to Mars (see London's Daily Mail) 

Footnote:  Maybe we should have left Buzz on the moon.  It was pretty expensive bringing him back.  

Second Space Disaster in a Week: One Dead

This has not been a good week for the private sector space industry.  Earlier today, Virgin Galactic's SpaceShipTwo crashed in the California desert during a test flight, killing one pilot and injuring a second pilot.  The spacecraft, built for space tourists, was using a new rocket fuel, which may have contributed to the accident. 

On its website, Virgin Galactic stated:

Virgin Galactic's partner Scaled Composites conducted a powered test flight of SpaceShipTwo earlier today. During the test, the vehicle suffered a serious anomaly resulting in the loss of the vehicle. The WhiteKnightTwo carrier aircraft landed safely. Our first concern is with crew and their families. We will work closely with relevant authorities to determine the cause of this accident and provide updates as soon as we are able to do so.

It has been 10 years since SpaceShipOne opened the door to space tourism, and this crash can only increase the wait for the hundreds who put down money to be part of the project. 

At a press conference earlier today, Stuart Witt, responsible for the Mojave Air and Space Port, said: 

We are doing this for you and your generation. It is a cause far greater than any one of us singularly. I compare it to the Magellan expedition [the first circumnavigation of the Earth].’

I don't think Magellan was running a tourist outfit back then, but I understand the sentiment.

Disaster Strikes Orbital Sciences' Rocket

Orbital Sciences' third resupply mission to the International Space Station ended in disaster earlier today as the rocket exploded shortly after liftoff in Virginia. Fortunately, the mission was only carrying cargo and not astronauts. Expect an extensive inquiry.  Stay tuned.

Update: I corrected my posting to note this was Orbital Science's third planned mission to the ISS. In terms of the accident, the company's website stated:

Orbital Sciences Corporation confirms that today’s Antares rocket launch from NASA’s Wallops Flight Facility was not successful. Shortly after lift-off from the Mid-Atlantic Regional Spaceport Pad 0A at 6:22 p.m. (EDT), the vehicle suffered a catastrophic failure. According to NASA’s emergency operations officials, there were no casualties and property damage was limited to the south end of Wallops Island. Orbital has formed an anomaly investigation board, which will work in close coordination with all appropriate government agencies, to determine the cause of today’s mishap.

This may mean more work for SpaceX to pick up the slack.

All is Well in the Martian Skies

I was glad to read that the various man-made Martian satellites survived the recent comet flyby (it helps that NASA had plenty of warning and placed the spacecraft at a safe distance to observe the event). With MAVEN having just arrived (Mars Odyssey and Mars Reconnaissance Orbiter have been orbiting for a while), as well as it's Indian peer, this could have been a problem. Given the numerous national failures to reach Mars, the last thing we need is a monster snow ball sweeping the survivors from the sky.  Comet C/2013 A1 Siding Spring  can now go back to rattling around the solar system. 

Great Image: Life Cycle in a Nebula

This Hubble Space Telescope image of a nebula shows emerging stars, fast-burning stars exhausting their fuel, and even planets trying to form from a disk of gas and dust.  We see a full spectrum of life to death in one image.  NASA explains:

From beginning to end, different stages of a star's life appear in this exciting Hubble Space Telescope picture of the environs of galactic emission nebula NGC 3603. For the beginning, eye-catching "pillars" of glowing hydrogen at the right signal newborn stars emerging from their dense, gaseous, nurseries. Less noticeable, dark clouds or "Bok globules" at the top right corner are likely part of a still earlier stage, prior to their collapse to form stars. At picture center lies a cluster of bright hot blue stars whose strong winds and ultraviolet radiation have cleared away nearby material. Massive and young, they will soon exhaust their nuclear fuel. Nearing the end of its life, the bright supergiant star Sher 25 is seen above and left of the cluster, surrounded by a glowing ring and flanked by ejected blobs of gas. The ring structure is reminiscent of Supernova 1987a and Sher 25 itself may be only a few thousand years from its own devastating finale. But what about planets? Check out the two teardrop-shaped objects below the cluster toward the bottom of the picture. Although larger, these emission nebulae are similar to suspected proto-planetary disks (proplyds) encompassing stars in the Orion Nebula.

Bookmark: The Copernicus Complex

Caleb Scharf, British-born astronomer and director of the Columbia Astrobiology Center at Columbia University, has written a story about our place in this expanding universe of ours.  His book, The Copernicus Complex: Our Cosmic Significance in a Universe of Planets and Probabilities, highlights how man's idea of himself and "life" itself has changed over time as sciences peels back more of the mysteries around us.

In reviewing the book, The Wall Street Journal writes: 

Nicolaus Copernicus is credited with the realization, in the 15th century, that the Earth does not sit at the center of the universe but orbits around the sun. This was a key step in the development of the idea that we do not occupy a special place in the universe and that, by implication, there may be nothing special about us, cosmically speaking. In the late 20th century, this led to the “principle of terrestrial mediocrity,” which says that our place in the universe is so ordinary as to be typical—that we live on an ordinary planet, orbiting an ordinary star, in an ordinary galaxy. Caleb Scharf argues that this approach, which he calls the “Copernicus complex,” has gone too far. The Earth, he says, is a rather unusual planet, situated in a rather unusual location.

London's The Guardian writes:

Forget the tricksy parenthesis in the subtitle. Skip past an early tendency to label scientists as budding, and science as cutting-edge. This book expands, like spacetime itself, from a very small point. It begins with the microscope pioneer Antony van Leeuwenhoek's famous discovery in Delft in 1674 of a microcosm in a drop of lake water, and it ends with speculation about a lonely civilisation, 100bn years on, in a freezing vacuum that no longer contains information about anything. Books such as these remind us that we are lucky to be here at all, and even luckier to be here now.

"New Martians Killed by Oxygen"

Let's hope we never read this headline, and it may be thanks to MIT students who identified a short-coming in the Dutch Mars One mission plans. Mars One represents the first effort of a private company to place humans on the surface of Mars. What the students found should be seen as helpful to the planners and one might wonder why it was not considered earlier.

MIT students Sydney Do, Koki Ho, Samuel Schreiner, Andrew Owens and Olivier de Weck conducted their own assessment of the Mars project, funded by NASA and others, and issued their results in a paper titled “An Independent Assessment of the Technical Feasibility of the Mars One Mission Plan.”  Among other things, they reported: 

Our assessment revealed a number of insights into architecture decisions for establishing a colony on the Martian surface. If crops are used as the sole food source, they will produce unsafe oxygen levels in the habitat.

Unfortunately, Mars One was not too receptive to the paper.  MarsOne co-founder and CEO Bas Lansdorp, in an email to SpacePolicyOnline, said he did not have time to respond to the comments and:

the lack of time for support from us combined with their limited experience results in incorrect conclusions.

Mr. Lansdrop may not have time, but if I was one of the volunteers hoping to win a one-way ticket to the Red Planet, I would be reading this report very carefully.

Should Pluto Be Returned to the Family of Planets?

Should we still be having this argument about whether or not Pluto is a planet? Is this a scientific duel, or more the earlier generation complaining that they still want to use the mislabeled name brontosaurus rather than Apatosaurus? I am fine with the 2006 decision to make Pluto a dwarf planet, but some at Harvard-Smithsonian Center for Astrophysics are still debating the topic. Last month, after hearing a debate among three leading experts in planetary science, the audience voted and decided that Pluto is still a Planet.  While this settles nothing, it was still a good debate (you can see it on YouTube at https://www.youtube.com/user/ObsNights).

I am more interested in labeling exoplanets rather than relabeling our neighbors, but I do not expect this issue to die anytime soon.  So while the local debate continues, I hope the telescopes will be trained on much more distant matters as we ponder the wild and strange universe. 

Will Putin Go to the Moon, Please?

Russia is talking about a manned mission to the moon by 2030, and I like the idea if Putin goes on the spacecraft. Why settle for the Crimea when virgin lunar locations await? He can take possession of the Sea of Moscow on the far side of the moon. 

According to media sources, Russia's Federal Space Agency (Roscosmos)  chief Oleg Ostapenko said:

Implementing the guidelines of the Basic Principles of Russia’s space policy till the year 2030 and for a longer perspective, we have begun design works of a new manned spaceship, which will be the first element of a future manned system along with new launch vehicles — carrier rockets of the heavy and super-heavy classes.

Of course, as I noted in my last post, there is the small issue of the Treaty on Principles Governing the Activites of States inthe Exploration and Peaceful Uses of Outer Space, including the Moon and Other Celestial Bodies, which states in Article II:

Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means. 

And Article IV states:

The moon and other celestial bodies shall be used by all States Parties to the Treaty exclusively for peaceful purposes. The establishment of military bases, installations and fortifications, the testing of any type of weapons and the conduct of military manoeuvres on celestial bodies shall be forbidden.

Then again, Russia does not seem to worry about treaties and promises.  Hence, strap on a suit, Vlad. The dark side of the moon awaits you.

World Space Week

From October 4th to 10th is World Space Week, designated as such by the United Nations since 1999.  And why these dates?  Because October 4, 1957, is the date Sputnik was launched and October 10, 1967, is the date of the Treaty on Principles Governing the Activites of States in the Exploration and Peaceful Uses of Outer Space, including the Moon and Other Celestial Bodies. 

Events to celebrate this week are scheduled throughout the states and the world.  For example, in Colorado Springs, Colorado, the Space Foundation is bringing NASA astronaut Dr. Leroy Chiao to Colorado Springs on October 9 to share his experiences as a Space Shuttle astronaut and resident of the International Space Station with 200 school children.  In DeWitt, Michigan, Anousheh Ansari, the first private female space explorer, will Skype with members of the Michigan Space Program (DeWitt High School students) on October 7, 2014 from 10:30 AM until 11:30 AM.
