Citizens in Space/TSG/SEDS balloon payload

Citizens in Space announces the successful completion of a high-altitude balloon flight, the first in a series of missions to test hardware designed to fly on the Lynx spacecraft from XCOR Aerospace.

The helium balloon, which reached an altitude of 25 kilometers (82,000 feet), was launched by a team from the University of Central Florida’s Students for the Exploration and Development of Space. Soon after launch, shifting winds carried the balloon west, rather than east, out over the Gulf of Mexico. The unexpected turn led to a scramble by UCF-SEDS students to locate the balloon, which was lost at sea for several days.

The balloon carried components from the Lynx Cub Payload Developer’s Kit, an open-source science kit available through Citizens in Space and Terran Sciences Group.

“The main goal on this flight was to test Dev Kit components by exposing them to extreme conditions,” said Dr. Justin Karl, Chief Payloads Officer for Citizens in Space. “Post-flight analysis by UCF-SEDS shows that components functioned normally throughout the flight at temperatures down to -50°C (-60°F) and atmospheric pressure below 1% of sea level. At the end, the payload survived a 17.5g water impact and an unexpected dip in salt water. These are far more extreme than the conditions we will experience during actual spaceflights on the XCOR Lynx, where payloads will ride comfortably inside the crew cabin and be subjected to only about 4g of acceleration.”

The flight also served as a launch-and-recovery test for the next Citizens in Space balloon mission, which will carry an ultra-high-definition video camera developed for the Lynx spacecraft.

“High-altitude balloons are a dime a dozen,” said Joseph Ricci, director of projects for UCF-SEDS, “Our mission was part of a larger program which will qualify hardware for use in future spaceflights.”

“This test gives us great confidence in the reliability of our Dev Kit components,” Dr. Karl said. “These components will be useful to groups at all levels, from middle-school classes to professional researchers, who want to fly experiments on the Lynx spacecraft. Anyone who’s interested in flying an experiment in space should visit or for more information on our Dev Kit components and no-cost flight opportunities.”

NASA has released a new desktop application for asteroid detection, developed by NASA and Planetary Resources Inc. based on an algorithm from NASA’s Asteroid Data Hunter Challenge.

Amateur astronomers can use the application to analyze images. The application will tell the user whether a matching asteroid record exists and offer a way to report new findings to the Minor Planet Center, which confirms and archives new discoveries.

The desktop application, which is free, currently runs on Macintosh and Windows computers. A Linux version is coming soon. The application can be downloaded at

The improved algorithm has the potential to increase the number of new asteroid discoveries by amateur astronomers. Analysis of main-belt asteroid images using the algorithm showed a 15 percent increase in positive identifications.

The application was announced during a panel discussion at the South by Southwest Festival in Austin, Texas on Sunday.

Earth and Moon from cockpit of XCOR Lynx spacecraft

This artist’s conception shows the Moon as it might appear from the cockpit of the XCOR Lynx spacecraft.

This is a sight that can only be seen from space: The Moon against a black sky, with the Earth in daylight. Fewer than .00001% of the world’s population have had the opportunity to see this sight. That number will increase dramatically in the next few years, when suborbital spaceflight becomes commercially available.

At first glance, the Moon appears oddly dark. We usually think of the Moon as being quite bright, almost a pure white. That’s because we’re used to viewing it at night when our eyes are dark adapted. In reality, the surface of the Moon is fairly dark, as shown by observations and photos taken by the Apollo astronauts and the samples they brought back. Seen from space, with the sunlit Earth as a reference, the Moon shows its true color.

Earth's atmosphere as seen from space

The High Altitude Astrobiology Challenge will be featured at the 2014 meeting of the 100 Year Starship Symposium, which takes place in Houston on 18-21 September 2014.

“Searching for Extraterrestrial Life at the Edge of Space” is one of two featured papers that will be presented during the Life Sciences in Space Exploration Track chaired by NASA astronaut Dr. Yvonne Cagle. The paper will be presented by Edward Wright, founder of the United States Rocket Academy and project manager for Citizens in Space.

The High Altitude Astrobiology Challenge seeks to develop a reliable means of collecting microorganisms from the extreme upper atmosphere (altitudes of 100,000 feet and above). Such organisms have been collected by high-altitude balloons, but balloons lack the reliability and controllability of reusable suborbital spacecraft now under development.

The other featured paper will be “When Biology Meets Exobiology,” by David Almandsmith and Dr. Carmen Nevarez of Khotso Consulting.

Symposium registration is now open.

James Cameron’s Deep Sea Challenge 3D documentary opens in theaters on Friday, 8 August.


The documentary tells the story of Cameron’s voyage to the bottom of the Mariana Trench, the deepest spot on Earth.

One little-known fact about Cameron’s Deep Challenge project is that two filmmakers died in a helicopter accident during the production — another indicator of the hazards of working at sea. This is comparable to the three astronauts who died during the Apollo program.

Rumor says that James Cameron is one of two citizen explorers who have agreed to pay Space Adventures $150 million apiece for a circumlunar flight on a Russian Soyuz, becoming the first humans to visit the Moon since Apollo 17.

The following experiments may inspire the creativity of citizen scientists who want to fly experiments in space. Performed aboard the International Space Station, they could easily be replicated aboard a suborbital flight. (We would like to remind everyone that our Call for Experiments is still open.)

In the first video, International Space Station science officer Don Petit uses an inexpensive speaker to demonstrate the effects of acoustical energy on water in a microgravity environment.


A variation on this experiment uses a different type of fluid, which does not behave in a classical “Newtonian” manner. In the following video, Don Petit uses a cornstarch mixture as an example of a non-Newtonian fluid.

Artist's conception of Kepler 186-f

Astronomers using NASA’s Kepler Space Telescope have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

While planets have been found in the habitable zone before, but all were at least 40 percent larger in size than Earth, and understanding their makeup is challenging. Kepler-186f is more reminiscent of Earth, NASA says.

"Red Dragon" Mars Sample-Return Mission Architecture

NASA could launch a Mars sample-return mission in 2022 without breaking the bank, according to an internal study conducted at NASA Ames Research Center. The mission would use a slightly modified version of SpaceX’s Dragon capsule, called Red Dragon.

Red Dragon could land two tons (twice the weight of the Mars Science Laboratory Curiosity) on the Martian surface. The payload would include a new Mars Ascent Vehicle, Earth Return Vehicle, and equipment to drill two meters into the Martian surface.

The NASA Ames study team presented a paper at the IEEE Aerospace Conference, which took place this week in Montana. Leonard David has details on

Astrobotic rover competing for Google Lunar X-Prize

The Google Lunar X-Prize has announced new Milestone Prizes, which will provide technological stepping stones (and near-term financial help) for teams that are competing for the $30 million grand prize.

Five teams have been selected to compete as finalists for the Milestone Prizes, which have a total purse of $6 million to be awarded this year.

Winning the $30-million Google Lunar X-Prize requires landing a probe on the surface of the Moon, moving at least 500 meters on the surface, and sending back specified data. Teams have been struggling to come up with funding for the competition, though. As a result, the X-Prize Foundation has been tweaking the rules to help competitors along.

The new Milestone Prizes and selected teams are:

Multiple teams can win each Milestone Prize.

Skybox Imaging has released the world’s first high-resolution, high-definition videos of Earth taken by a commercial remote sensing satellite. Taken by SkySat-1, the first a planned constellation of 24 satellites, the video clips (have not yet been calibrated or tuned) show high-resolution views of Tokyo, Bangkok, Baltimore, Las Vegas, and Aleppo, Syria.


SkySat-1 can capture video clips up to 90 seconds long at 30 frames per second. The resolution is high enough to view objects like shipping containers that affect the global economy. (In these clips, you can make out automobiles moving along the highways.)

SkySat-1 is capable of sub-meter native color and near-infrared imagery. Other unique capabilities based on Skybox’s proprietary technologies will be announced in the near future. But the most revolutionary aspect is the cost, according to Skybox CEO Tom Ingersoll.

“SkySat-1 was built and launched for more than an order of magnitude less cost than traditional sub-meter imaging satellites,” Ingersoll said. “This extremely high performance satellite is made possible by proprietary technologies developed by Skybox, including the integrated satellite and imaging systems designs, which enable Skybox to launch a constellation of satellites that can provide imagery timeliness, quality and dependability that was never before possible.”

Skybox foresees numerous business applications for satellite imagery dynamic satellite video, including supply-chain and industrial-plant monitoring, maritime awareness, and environmental/humanitarian relief.

Skybox has raised $91 million from venture-capital firms Khosla Ventures, Bessemer Venture Partners, Canaan Partners and Norwest Venture Partners. It is preparing to launch SkySat-2 in early 2014.

For whatever reason, there seems to be a pre-Christmas rush on planetary press conferences and announcements. In the last six days, three separate projects have revealed details of their plans for robotic missions to the Moon and Mars.

Moon Express

Last Thursday, Moon Express unveiled its MX-1 lunar-lander design in front of 10,000 people at the closing session of Autodesk University in Las Vegas.

Moon Express, which is competing for the Google Lunar X-Prize, said the lander will use hydrogen peroxide and kerosene as propellents. Hydrogen peroxide can also be used, by itself, as a monopropellent. Moon Express noted that hydrogen peroxide can be manufactured from water that is available on the Moon, which it believes “would be a game changer in the economics of lunar resources and solar system exploration.”

The Arduino development team has announced two new boards, which may be of interest to Lynx Cub payload developers.

Intel Galileo Arduino board

The Intel Galileo is the first Arduino board to use an Intel processor. Galileo is based on a 400-MHz Intel Quark SoC X1000 Application Processor, a 32-bit Pentium-class system on a chip with 16 KByte L1 cache and 512 KBytes of embedded SRAM.

The board runs Linux and features a full-sized mini-PCI Express slot, 100Mb Ethernet port, Micro-SD slot, RS-232 serial port, USB Host port, USB Client port, and 8MByte NOR flash memory. It is pin-compatible with Arduino shields designed for the Uno R3 and operating at either 3.3 or 5V.

The Galileo board is 4.2 inches long by 2.8 inches wide, so it will not quite fit into a 1U Cub payload. It will, however, fit nicely into a 2U Cub payload.

Intel plans to donate 50,000 Galileo boards to 1,000 universities over the next 18 months. The board will be available November 29, 2013.

Arduino TRE board

The Arduino TRE uses the 1-GHz Sitara AM335x ARM Cortex-A8 processor from Texas Instruments, which provides up to 100 times the performance of an Arduino Uno or Leonardo.

The Arduino TRE, which was developed in cooperation with the BeagleBoard Foundation, is actually two Arduinos in one: a Sitara-based Linux Arduino and a full AVR-based Arduino which enables the Arduino TRE to use existing Arduino shields. On the Linux side, the TRE can run high-performance desktop applications, processing-intensive algorithms, and high-speed communications. It appears that the TRE will be produced by CircuitCo in Richardson, Texas, which also produces the BeageleBoard and BeagleBone.

The board has an XBee radio socket as well GPIO headers for the ARM processor and Arduino form-factor headers for the AVR processor. Ports include USB (2), micro-USB, Ethernet, HDMI, and Audio In/Out. The board also has XBee radio, GPIO, and Arduino form-factor headers.

The Arduino TRE will be available in spring of 2014.

Pricing for the Arduino TRE and Galileo boards has not been announced.

NASA is funding work on a new propulsion system that may enable a 10-kilogram (22-point) CubeSat mission to Europa.

Nathan Jarred of the Universities Space Research Association has received a $100,000 Phase I award from the NASA Institute of Advanced Concepts to study a dual-mode propulsion concept that pairs electric and thermal propulsion.

High-efficiency electric propulsion would be used for interplanetary maneuvers, with higher-thrust thermal propulsion reserved for quick Earth orbit escape, drastic orbital maneuvering and orbital insertion at the destination.

Jarred will use the NIAC money to design and optimize the various components of the overall system. He will also design an experiment to evaluate propellant performance within the thermal mode using existing hardware at the Center for Space Nuclear Research.

CubeSat technologies may be the antidote to the growing cost of NASA interplanetary missions. The interplanetary CubeSat missions currently under study are generally limited to the inner solar system, however, due to the propulsion problem. New concepts like this one could change that.
