Proposed Balloon Ride Would Let You See The Blackness Of Space

Doesn’t that look fun? A startup company is proposing to send customers 19 miles (30 kilometers) into the air via balloon, where they can linger for two hours and look at the curvature of the Earth and experience a black sky. While it’s not high enough to qualify as a spaceflight, the listed ticket price may be a little more affordable for space enthusiasts: $75,000.

Don’t get too excited yet — the project appears to be in very early stages, and no “first flight” date is listed yet. But there are some interesting notes for those looking for space and science experience in the company.

Among the members of its executive is Alan Stern, the principal investigator for the New Horizons Pluto mission and NASA’s former associate administrator for the science mission directorate. (He’s also the CEO of the Golden Spike company that wants to offer commercial human missions to the moon.)
The executive also includes Jane Poynter and Taber MacCallum, who were both members of Biosphere 2. More recently, they also took on senior positions in Inspiration Mars, a Dennis Tito-led project that aims to send humans past Mars. (The target launch date for that is Jan. 5, 2018.)
The company proposing to build it is Paragon Space Development Corp. (which Poynter and MacCallum co-founded.) Paragon’s customers for thermal, environment and life support systems include a lot of name brands (including NASA). Paragon is also doing work for the Inspiration Mars project as well as Mars One, which aims to send colonists on a one-way trip to the Red Planet by 2023.

“Seeing the Earth hanging in the ink-black void of space will help people realize our connection to our home planet and to the universe around us, and will surely offer a transformative experience to our customers,” stated Poynter, who is CEO of World View. “It is also our goal to open up a whole new realm for exercising human curiosity, scientific research and education.”

World View’s announcement came after the Federal Aviation Administration “determined that World View’s spacecraft and its operations fall under the jurisdiction of the office of Commercial Space Flight,” the company added.

More information on their mission is available on the World View website. It’s a bit of a different track than Virgin Galactic and XCOR, who are offering rides into suborbital space for prices of $250,000 and $95,000, respectively. Neither company has an operational spacecraft yet, but they are in flight testing. Reports indicate they are hoping to get flights going next year.

Wow! That was our reaction to seeing this picture (and others) of a light show aboard the International Space Station. After confirming with NASA that the images circulating lately on social media are real, we were directed to the Japan Aerospace Exploration Agency (JAXA), who co-ordinated this experiment.

The work is called “Auroral Oval Spiral Top” and was done in the Kibo module on May 12, 2011, JAXA said. This was the second version of the experiment, which initially ran April 30, 2009 during Expedition 19.

“Auroral Oval Spiral Top uses a spinning top that has arms illuminating with LED linear light sources and point light sources. Various movements of the spinning top floating in microgravity show aurora-like light traces,” JAXA stated on a web page about the experiment.

The project, JAXA added, is “designed to produce aurora-like luminescence traces using a spinning top with both linear and point light sources. In microgravity, the center of gravity of the spinning top continuously and randomly moves while it is spinning. Using the characteristics of the top in microgravity, the project tries to produce various light arts using its unexpected movements/spins, by changing attaching locations of its arms and weights.”

Takuro Osaka, a professor at the University of Tsukuba, was the principal investigator of this art project. What are your favorite experiments performed by astronauts in space? Let us know in the comments.

With two days left before Planck switches off forever, the European Space Agency re-posted this beautiful image the telescope recently assisted in taking. It shows the Shapley Supercluster, which ESA describes as the biggest cosmic structure in our neighborhood.

First discovered in the 1930s by Harlow Shapley, a U.S. astronomer, the structure has more than 8,000 galaxies and a mass that is 10 million billion times that the mass of the Sun, ESA added. The blue parts are detections by Planck, and the Rosat satellite imaged the pink sections. Visible wavelengths shown in the picture come from the Digitised Sky Survey.

Today (Oct. 21), ESA will order Planck to run its thrusters to empty. After years hovering at a Lagrange point, the telescope will be put in a “parking orbit” to circle the sun, keeping it away from the Earth and moon for at least several centuries. The last command will be sent Oct. 23.

Among other milestones, Planck released a cosmic map in March refining the Universe’s age to 13.82 billion years.

Here’s Your Chance To Fund A New Asteroid Search

The crowdfunding campaign is off to a slow start, but the PHASST-1 telescope still has more than a month to reach its $88,816 (€65,000) goal of deploying telescopes devoted to searching for near-Earth asteroids.

The Potentially Hazardous Asteroid Search & Tracking Telescope, as the acronym stands for, will begin with two telescopes: an f/1 Baker-Nunn camera near Arequipa, Peru and a 50cm f/3.6 astrograph near Ager, Spain.

“Even though PHASTT-1 will have a large field of view compared to most telescopes (~5x) of a similar aperture, competing in the area of asteroid search is difficult due to a large number of teams doing similar work. Because of this, we are designing PHASTT-1 as not only a search telescope but also as a followup and characterization instrument — two key areas where we can make an impact,” the IndieGogo campaign page states.

“Follow-up observations are important as they help us refine the orbits of potentially hazardous objects and narrow the uncertainties around how close an asteroid will come to the Earth. Characterization of asteroids is also important as it helps us understand the physical properties of asteroids. This understanding critical if we want to know how to best deal with a ‘rogue’ asteroid that is on an impact course or if we just want to know which asteroids would make for interesting near-Earth exploration targets.”

The principles including astronomers, a technology consultant and a laser ranging specialist. You can read more technical details on the IndieGogo campaign page or the PHASTT-1 website. If they get the money they need, they aim to be operational by the middle of next year. The campaign completes Nov. 26.

NASA: Less Than 1% Chance That Asteroid 2013 TV135 Will Hit Earth In 2032

Credit: NASA/JPL-Caltech

We’ll skip straight to the good news: NASA says Earth is likely safe from Asteroid 2013 TV135. Calculations put the newly discovered asteroid’s chances of hitting the planet in 2032 at incredibly small — 1 in 63,000 — despite some alarmist news reports.

“To put it another way, that puts the current probability of no impact in 2032 at about 99.998 percent,” stated Don Yeomans, manager of NASA’s Near-Earth Object Program Office.

“This is a relatively new discovery. With more observations, I fully expect we will be able to significantly reduce, or rule out entirely, any impact probability for the foreseeable future.”

Asteroid 2013 TV135 in a series of images snapped by amateur astronomer Peter Lake.

The asteroid was first spotted on Oct. 8 by scientists at the Crimean Astrophysical Observatory in Ukraine. It’s 1,300 meters (400 feet) in diameter and cycles in an orbit that goes three-quarters of the way out to Jupiter, and then back again towards its closest approach near Earth’s orbit.

The asteroid came within 4.2 million miles (6.7 million kilometers) of Earth on Sept. 16. Amateur astronomer Peter Lake uploaded a video (which you can see above) based on a few pictures he took Oct. 17-18.

“Its important to remember that new asteroids (this one has only 9 days of arc) usually don’t stay on the Torino Scale (the risk register) for long, as further data updates increase the precision of the orbit, and usually quickly remove them as potential impactors,” Lake added in a blog post.

There are many, many international efforts to watch asteroid paths and disseminate the information to the public. One of them is NASA’s Asteroid Watch website, where you can get the latest information on nearby space rocks.

Beer brewing in space? That’s what a preteen student will ask astronauts to do on the International Space Station soon. “By combining the four main ingredients (malt barley, hops, yeast, and water) of beer in space, will we be able to produce alcohol?” reads the research proposal from Michal Bodzianowski. If you follow the link, you can see how this also has medical applications on station, as alcohol can disinfect wounds.

Michal was a selectee in last year’s Student Spaceflight Experiments Program, which we’ve written about before. The program now has a new call for proposals.

“Each participating community will be provided a real microgravity research mini-laboratory capable of supporting a single experiment, and all launch services to fly it to the space station in fall 2014,” a press release stated.

The design competition, the release added, “allows student teams to design and formally propose real experiments vying for their community’s reserved mini-lab on space station. Content resources for teachers and students support foundational instruction on science in microgravity and experimental design.”

Inquiries must be sent by Nov. 20, and participating communities must sign up by Feb. 17, 2014. Final selection will take place in May.

For more information, you can visit the Student Spaceflight Experiments Program website. The program has participation from the National Center for Earth and Space Science Education, the Arthur C. Clarke Institute for Space Education, and NanoRacks.

Below is SSEP’s description of the five categories of participation:

Pre-College (the core focus for SSEP) in the U.S., (grades 5-12), with school districts—even individual schools—providing a stunning, real, on-orbit RESEARCH opportunity to their upper elementary, middle, and high school students (Explore the 60 communities that participated in the first six flight opportunities to date)
2-Year Community Colleges in the U.S., (grades 13-14), where the student body is typically from the local community, providing wonderful pathways for community-wide engagement
4-Year Colleges and Universities in the U.S., (grades 13-16), with an emphasis on Minority-Serving Institutions, where the program fosters interdisciplinary collaboration across schools and departments, and an opportunity for formal workforce development for science majors
Communities in the U.S. led by Informal Education or Out-of-School Organizations, (e.g., a museum or science center, a home school network, a scout troop), because high caliber STEM education programs must be accessible to organizations that promote effective learning beyond the traditional classroom
Communities Internationally: in European Space Agency (ESA) member nations, European Union (EU) member nations, Canada, and Japan, with participation through NCESSE’s Arthur C. Clarke Institute for Space Education. Communities in other nations should explore the potential for their participation by contacting the Institute at http://clarkeinstitute.org

Tilt-A-Whirl! A Tale Of Strange Planetary Orbits In Kepler-56

A faraway group of planets is puzzling scientists. Newly reported Kepler-56’s system has three planets — two smaller ones close by, and a much larger one further out. The inner planets are orbiting at a tilt to the equator of the host star.

Scientists have seen that tilt before in other systems, but they thought you would need a “hot Jupiter” — a huge gas giant planet close to the star — to make that happen. Here, that’s not the case. The outer planet’s gravity, distant as it is, is pulling the two planets into their tilted orbits.

“This is a very puzzling result that is sure to challenge our understanding of how solar systems form,” stated co-author Tim Bedding, a physics researcher at the University of Sydney.

Kepler-56 is 3,000 light-years away from Earth and has a mass about 30% greater than that of our Sun. As the name implies, astronomers used the Kepler space telescope to make the discovery.

Topsy-Turvy Aurora Caught On Astronaut’s Camera

"The pic doesn't do the northern lights justice. Covered the whole sky. Truly amazing!" wrote NASA astronaut Mike Hopkins on Twitter Oct. 9.

Isn’t that aurora facing the wrong way? Not if you’re in space!

NASA astronaut Mike Hopkins tweeted this picture from his perch on the International Space Station a few days ago. He sounds jazzed to be on his first mission: “Can’t believe this is really me from the Cupola and that I’ve been in space for almost 3 weeks now!” he wrote on Twitter Oct. 15.

We’d be pretty excited, too! Luca Parmitano (from the European Space Agency) is also on his first trip into space. In between their many experiments, the rookies must relish the opportunity to take pictures of the view. Which image of theirs below is your favorite? Did we miss any notable shots? Let us know in the comments.

Here’s A Nine-Billion-Year Old Gravitational Lens In Space

Here’s a picture of what deflected light looks like from 9.4 billion years away. This is the most faraway “gravitational lens” that we know of, and a demonstration of how a galaxy can bend the light of an object behind it. The phenomenon was first predicted by Einstein, and is a handy way of measuring mass (including the mass of mysterious dark matter.)

“The discovery was completely by chance,” stated Arjen van der Wel, who is with the Max Planck Institute for Astronomy in Heidelberg, Germany.

“I had been reviewing observations from an earlier project when I noticed a galaxy that was decidedly odd. It looked like an extremely young galaxy, but it seemed to be at a much larger distance than expected. It shouldn’t even have been part of our observing program.”

The alignment between object J1000+0221 and the object in behind is so perfect that you can see rings of light being formed in the image. Scientists previously believed this kind of lens would happen very rarely. This leaves two possibilities: that the astronomy team was lucky, or there are way more young galaxies than previously thought.

This schematic image represents how light from a distant galaxy is distorted by the gravitational effects of a nearer foreground galaxy, which acts like a lens and makes the distant source appear distorted, but brighter, forming characteristic rings of light, known as Einstein rings. An analysis of the distortion has revealed that some of the distant star-forming galaxies are as bright as 40 trillion Suns, and have been magnified by the gravitational lens by up to 22 times. Credit: ALMA (ESO/NRAO/NAOJ), L. Calçada (ESO), Y. Hezaveh et al.

“Gravitational lenses are the result of a chance alignment. In this case, the alignment is very precise,” a press release on the discovery stated.

“To make matters worse, the magnified object is a starbursting dwarf galaxy: a comparatively light galaxy … but extremely young (about 10-40 million years old) and producing new stars at an enormous rate. The chances that such a peculiar galaxy would be gravitationally lensed is very small. Yet this is the second starbursting dwarf galaxy that has been found to be lensed.”

“This has been a weird and interesting discovery,” added van der Wel. “It was a completely serendipitous find, but it has the potential to start a new chapter in our description of galaxy evolution in the early universe.”

The research will be available soon in the Astrophysical Journal; in the meantime, check out a preprint version on Arxiv.

NASA Celebrates Return To Work, But Shutdown’s Shadow Could Linger

A message on the NASA 360 Twitter feed the day employees returned to work after a 16-day government shutdown in October 2013.

After 16 days off the job, most employees at NASA returned to work today (Oct. 17). The good news came after a late-night deal by U.S. politicians to reopen government activities until Jan. 15 and raise the debt limit — originally expected to expire today — until Feb. 7. Democrats and Republicans were battling over the implementation of a new health care law; more details on how the deal was reached are available in this New York Times article.

During the shutdown, only mission-essential functions at NASA were completed except at areas such as the Jet Propulsion Laboratory, which are run by contractors. Twitter, Facebook and social media updates went silent. Missions were run on a needs-only basis, and for a while it looked as though the upcoming MAVEN mission to Mars might be delayed (although it got an exception due to its role as a communications relay for NASA’s rovers.)

So you can imagine the happiness on social media when NASA employees returned to work.

Given the length of the shutdown, not all work can just start immediately. Experiments have been left unattended for more than two weeks. Equipment needs to be powered back on. Cancelled meetings and travel arrangements need to, as it is possible, be rebooked.

At NASA’s Marshall Space Flight Center, spokesperson Don Amatore asked employees to be mindful of safety precautions, according to All Alabama. He also stated that “liberal leave” is in effect for employees today and on Friday, meaning that employees are able to take time off without requesting it beforehand — as long as their supervisors know.

Several Twitter reports from NASA contractors on Thursday also indicated that they were unsure if they would be coming back to work on that day, or at some point in the near future. The agency, however, was reportedly sending automated telephone updates to employees and contractors advising them to check with their supervisors for information.

The long-term effects of the shutdown are still coming to light. Certain NASA researchers who planned Antarctic work this year may lose their entire field season. Also, some researchers using NASA or government telescopes missed their “window” of telescope time. “SOFIA remains grounded as a testament to stupidity. Europa keeps her secrets,” wrote Mike Brown, a professor of planetary astronomy at the California Institute of Technology, on Twitter Oct. 13 about NASA’s Stratospheric Observatory for Infrared Astronomy.

Additionally, the S&P ratings agency noted that the U.S. economy lost $24 billion due to the shutdown, which is more than the initial $17.7 billion request for NASA’s budget in fiscal 2014. Given the agency is in the midst of budget negotiations and is worried about the viability of the commercial crew program, among other items, any long-term economic damage could hurt NASA for a while.

NASA and other government agencies also have only three months of relative stability until the government reaches another funding deadline. What do you think will happen next? Let us know in the comments.
