For this Throwback Thursday, I’d like to open with a classic movie scene:
Well, don’t worry, the world won’t end, but I can promise you an epic, blood red moon! There will be a super moon, a blood, moon, and a lunar eclipse all on the same day on September 27th, and I can’t wait to see it!
Read more about it here at Space.com http://www.space.com/30546-supermoon-blood-moon-total-lunar-eclipse.html
If you want to read more about and red moons, click on some of my previous posts below.
As I’m sure you probably know, this is the very day that NASA’s Rosetta spacecraft has landed on a comet to peer into an object that has fascinated and terrified humanity for thousands of years! If you click on the link below, you can see the official NASA page of the mission, with pictures, a timeline, and video coverage of the mission.
In honor of this momentous occasion, I’ve created a short presentation for you about comets. Feel free to use it in class, but please give me credit!
I’ll be writing more later in the week about the significance of this mission, but for now, enjoy this presentation, and enjoy watching this incredible mission online!
That’s right, you heard me. Only a few hours ago, pop star, activist, and all around weirdo performance artist Lady Gaga, confirmed that she will be the first artist to perform IN SPACE, as part of the Virgin Galaxy’s maiden voyage in 2015. This will also mark the first ever commercial flight into space, which is certainly cause for celebration. I for one am enthusiastic about this new artistic presence in space. and glad that they picked someone as out-of this world as Gaga. For one thing, if the ship is commendeered by aliens, she’ll probably speak their langugage 😉

Today the GOCE European Space sattelite came crashing down to the South Atlantic Ocean! Scientists caution that there is a huge garbage dump of sattelites orbiting our planet and that this could happen again at any moment. The lesson here appears to be: “Space to Earth, CLEAN UP YOUR SKY!”
Not only is this the biggest Moon of the year, it’s also one of the most interesting. June 23rd’s full moon is classified as a “Strawberry Moon,” or “Rose Moon” It was called Strawberry by the Algonquin Native Americans because they knew this full moon was an ideal time to gather fruit. To learn more about this particular full moon, I’ve posted a link to a video created by the good folks at “The Farmer’s Almanac”, a trusted astronomy resource for over 100 years.
So I hope to see some of you down at Primland to look at this beautiful full moon. I know I’ll be training the telescope on it!
Hi everyone, and no, that is not a typo- Today marks not only the celebration of Earth Day on our planet, it also heralds the discovery of not one, not two but THREE Earth-like planets!
Just three days ago, the Kepler Space Telescope, which is designed to look for planets beyond our solar system, discovered a group of planets known as Kepler 62b, 62c, 62d, 62e and 62f. These planets come from two star systems over 1,200 light years away. Although the discovery was a few days ago, we’re celebrating now because it coincides with the celebration of our own planet.
Now, there are over 600 confirmed extra-solar planets in our galaxy and certainly there may be many, many more, but these planets are special because they orbit their respective stars within what’s called the “habitable zone,” that is, a safe distance from the star that keeps the planet from being scorched like Mercury, or frozen like Neptune. Since we can’t actually see the surface of these planets, this is our best guess to determine if a planet is capable of supporting life.
This isn’t the first time scientists have attempted to find inhabited planets in this century. In our tours at Primland, we go into detail about the search for Earth like planets outside our solar system in our presentations, including the search for planets that might be inhabited by intelligent life! Hope you’ll come down and join us soon!
So Happy Earth Day everyone! Also, (as a special bonus), I thought I’d include a video of Earth from space, so that you can see our planet in a new, special light:
That’s right, today is the 23rd anniversary of the Hubble Space Telescope’s year in space. Its mission: observe the furthest objects ever seen in our universe, further beyond any human’s reach. After 1,000,000 peeps through the mighty space telescope, scientists have learned more than ever thought possible about the origins of our universe, the nature of planets beyond the Earth, and our place in the cosmos. Just today, Hubble scientists released a photo of the Horsehead Nebula, which Hubble last photographed in 2001. Using infra-red light, the telescope peered deeper into this mysterious dark cloud, and found the filaments that give it structure. Check it out in the video below!
If you like looking at Hubble photos like I do (and who doesn’t?), check out their facebook page, and their website: http://www.spacetelescope.org/, which also has videos, merchandise, and educational materials for teachers and students.
Well, the Curiosity Rover is still working, though it will be unable to communicate with the Earth for over a month. However, it won’t stop working, using its 10 scientific instruments to peer into the chemical, geological, and atmospheric makeup of Mars. Today I want to give you a general overview of the project, and some of its hopes and dreams; above all, the dream of finding life. Curiosity has the tools to find the building blocks of life, not just water but the chemical compounds that allow us to exist on Earth. If Curiosity can find these on Mars, someday we may be able to sent people to Mars and make it a new home for sustaining Earth plants and animals on another world.
What Is Curiosity?
The Curiosity is a rover, a robot that can roll around the surface of another planet, taking pictures, soil and gas samples and other scientific data back to Earth.
What’s It Up To?
Curiosity’s basic objective is to investigate the presence of water on Mars. As far as we know, water is the essential ingredient of all life. Other NASA missions have found clues that there was water on Mars, but in order to get a better view of Mars, Curiosity is here to use its advanced instruments to find a clear answer. Curiosity also trying to find clues in the Martian atmosphere, to see how different it is from Earth. Just yesterday, after 248 days on Mars, NASA announced that ancient Mars could have supported life:
“We have found a habitable environment that is so benign and supportive of life that probably — if this water was around and you had been on the planet, you would have been able to drink it,” said John Grotzinger, NASA’s chief scientist for the Curiosity Project.
11 Cool Facts About the Curiosity Rover
- The mission cost $2.5 billion!
- The MSL spacecraft was launched from Cape Canaveral FLA, the same place where in 1971, NASA launched the first ever spacecraft to orbit Mars, (Mariner).
- Around 1,000 people gathered in New York City’s Times Square, to watch NASA’s live broadcast of Curiosity’s landing.
- The landing site of the Curiosity Rover is called the “Bradburry Landing Site,” named in honor of author Ray Bradburry, author of “The Martian Chronicles,” who died just two months after the rover landed.
- The Bradbury landing site rests within a 3.5 billion year old crater that could have actually been formed by wind erosion and water sediment, which is one reason for the trip- to discover whether Mars could potentially support life as we know it, or if it did support life in the past.
- Because of the vast distance between Earth and Mars, it took over 7 minutes to send a message from the Curiosity Rover to the scientists over at the Jet Propulsion Laboratory, a period which the JPL dubbed, “The Seven Minutes of Terror”
- Just two days ago, (4/9/13) Curiosity found proof that the Martian atmosphere used to be thicker, and more Earth like. Now the atmosphere is mostly full of Greenhouse gases, which suggests that some kind of Global Warming might have happened on Mars
- The Rover is about the size of a small car, and weighs about 2,000 pounds
- Curiosity is powered by a small Nuclear Reactor, called a Radioisotope Thermoelectric Generator
- The Rover actually has a lucky penny! To calibrate its complex cameras, the rover has a 1980 Lincoln penny attached to its Mars Hand Lens Imager
- Curiosity is the only robot in the solar system to have a Twitter Account, which by the way, has been nominated for a Webby Award. If you visit the page and like what you see, you can vote to make Curiosity, a very happy interplanetary robot.
Key moments in the Curiosity Timeline
- November 26, 2011- The MSL spacecraft, containing the Curiosity Rover, launches from Cape Canaveral
- August 6, 2012- The Curiosity Rover lands on Mars, after a journey of 127 million miles.
- August 7th, 2012- First pictures from the surface of Mars. Later photos would also be broadcast in 3D!
- August 22nd- Curiosity Rove tests out its on-board laser, and tests its driving motors around the surface of Mars.
- August 29- Curiosity beams a song from the surface of Mars back to Earth, composed by Will.I.am from the Black Eyed Peas.
- September 27th- The rover discovers the remnants of an ancient river bed on Mars, making a great case for the existence of water.
- October 27th- Curiosity discovers mysterious pockets of Methane gas below the surface of Mars, which might be by-products of microscopic life forms.
- November 24th- Curiosity tracks a dust storm on Mars.
- February 7th- Curiosity starts drilling into the surface of Mars, to find the chemical composition of the soil.
- March 12th- Samples from the drilling uncover evidence of ancient microorganisms, and chemicals that are necessary building blocks for Carbon-based life.
- April 9th- The Curiosity Rover’s atmospheric sensors show the gradual decay of the atmosphere from primarily oxygen and argon rich, to mainly Carbon Dioxide, not unlike the Greenhouse Gasses in our atmosphere.
So, I hope you’ve enjoyed this re-cap of Curiosity’s great career so far, and we wish it luck as it wonders on alone, without parental supervision from Earth. If you want to see Mars yourself, you’ll have to wait until its path takes it away from behind the Sun, on June 20th.

So, I know I’m really late on this, but I wanted to give a very warm thank you to Dr. Richard Obousy for agreeing to come down to Primland last week, and talk about his company Icarus Interstellar. Here are a few notes I took during his presentation.
Part 1- Background On Dr. Obousy, and the Icarus Project
Dr. Obousy has had a longstanding interest in space travel and physics. He holds a Ph.D in theoretical physics, and worked for the UK Defense Evaluation and Research Agency (DERA) as a radar physicist from 1999-2002. He currently works as president of Icarus Interstellar, and Founder and Manager of CitizenShipper LLC. Dr. Obousy has written for over 15 peer-reviewed publications, and appeared on such television and radio programs as the History Channel series “The Universe,”
Icarus Intersellar is nonprofit, 70 volunteer group with the goal of creating spacecraft that can fly beyond our solar system, and reach closest stars by the year 2100. The team comes from all over the world, pooling research over the internet. The group was started in 2009, as an outgrowth of Project Daedalus, a project begun in 1973 by the British Interplanetary Society.
The project is split into 20 modules designed to plan out every stage of development, propulsion, and communication within the 100 year time span. On the project’s website, readers can download a complete report on the project, and learn about updates.
What’s wrong with our current spacecraft technology?
According to Dr. Obousy, the space shuttle can go 6 km per second, which means it could reach Pluto in 23 years, but would take thousands of years to go to our nearest star, Proxima Centauri. This is simply not fast enough to get past our solar system, and begin to actually touch the cosmos. Dr. Obousy, (and the crew at Icarus Interstellar) then touched on some of the potential benefits of superior space travel, such as mining for natural resources, and finding life on Mars, or Jupiter’s moon Europa. He cited the fact that data from the Curiosity and Viking spacecraft about life on these worlds is actually inconclusive! There might actually still be life in our solar system for us to still discover.
Although SETI (the Search For Extra-terrestial Intelligence) is currently scanning the skies for ET, Dr. Obousy feels that the “fleeting epoch of radio telescopes,” is no guarantee of success. Based on the findings from the Kepler Space Telescope, there may be over 400 billion planets in Milky Way, of those there might be as many as 100 billion Earth-like worlds. Dr. Obousy asserts that just because it is very difficult to locate extra-terrestrials, does not mean that they aren’t there.
How Project Icarus is Different From Current Spaceships.
Most of Project Icarus is devoted to using fusion power, rather than chemical energy, which, (if the project can perfect the process), could yield more than 10 million times more energy than the current design.
Why Did they Choose the Name “Icarus”?
For those of you who don’t know Greek mythology, Icarus was the son of the great engineer Daedalus, who created a pair of wax wings to give himself and his son the ability to fly. Unfortunately, the boy was so excited by this new power, and flew too close to the Sun, melting his wings, and sending the boy plummeting to his death. Understandably, this tragic story might seem like an odd source for the name of a company that designs space ships, but Dr. Obousy explains that, despite the outcome, Icarus, “pushed technology to its limits to discover hidden flaws,” which is how the story becomes one of the mantras to inspire the team.
Icarus is hopeful that they may some day create new technology that would allow us to travel at light speed, by dilebrerately warping space and time to travel through space at speeds that are unimaginable right now. Dr. Obousy cited many physicists that back up the idea that space time is not limited by light speed, and that there are natural sources of power such as dark energy and solar photons, that could be harnessed to propel spacecraft, (though at present, the energy required would be considerable to say the least). In the video above, you can get a glimpse of how Dr. Obousy suggested using such phenomena as the Casimir effect, and its ability to control dark energy as a sort of warp drive, using real scientific principles.
The Icarus Program is still fraught with challenges- monetary, resources, time, and of course the seemingly impossible difficulties creating real life interstellar vehicles, but Dr. Obousey and his team from Icarus Interstellar remain hopeful that “If we throw down the gauntlet, (i.e. challenging the members of his group), we will rise to the challenge like we did in the Apollo program,” which would allow us to take another great step in the field of science, and ultimately the human race.
Once again, I have to thank Dr. Obousy for his inspiring talk, and hope that he will visit Primland again soon!
