NASA tested new “eyes” for its next Mars rover mission on a rocket built by Masten Space Systems in Mojave, California, thanks in part to NASA’s Flight Opportunities Program, or FOP.
The agency’s Jet Propulsion Laboratory in Pasadena, California, is leading development of the Mars 2020 rover and its Lander Vision System, or LVS. In 2014, the prototype vision system launched 1,066 feet (325 meters) into the air aboard Masten’s rocket-powered “Xombie” test platform and helped guide the rocket to a precise landing at a predesignated target. LVS flew as part of a larger system of experimental landing technologies called the Autonomous Descent and Ascent Powered-flight Testbed, or ADAPT.
LVS, a camera-based navigation system, photographs the terrain beneath a descending spacecraft and matches it with onboard maps allowing the craft to detect its location relative to landing hazards, such as boulders and outcroppings.
The system can then direct the craft toward a safe landing at its primary target site or divert touchdown toward better terrain if there are hazards in the approaching target area. Image matching is aided by an inertial measurement unit that monitors orientation.
The Flight Opportunities Program funded the Masten flight tests under the Space Technology Mission Directorate. The program obtains commercial suborbital space launch services to pursue science, technology and engineering to mature technology relevant to NASA’s pursuit of space exploration. The program nurtures the emerging suborbital space industry and allows NASA to focus on deep space.
Andrew Johnson, principal investigator in development of the Lander Vision System development, said the tests built confidence that the vision system will enable Mars 2020 to land safely.
“By providing funding for flight tests, FOP motivated us to build guidance, navigation and control payloads for testing on Xombie,” Johnson said. “In the end we showed a closed loop pinpoint landing demo that eliminated any technical concerns with flying the Lander Vision System on Mars 2020.”
According to “Lander Vision System for Safe and Precise Entry Descent and Landing,” a 2012 abstract co-authored by Johnson for a Mars exploration workshop, LVS enables a broad range of potential landing sites for Mars missions.
Typically, Mars landers have lacked the ability to analyze and react to hazards, the abstract says. To avoid hazards, mission planners selected wide-open landing sites with mostly flat terrain. As a result, landers and rovers were limited to areas with relatively limited geological features, and were unable to access many sites of high scientific interest with more complex and hazardous surface morphology. LVS will enable safe landing at these scientifically compelling Mars landing sites.
An LVS-equipped mission allows for opportunities to land within more challenging environments and pursue new discoveries about Mars. With LVS baselined for inclusion on Mars 2020, the researchers are now focused on building the flight system ahead of its eventual role on the Red Planet.

Want to take a relaxing interstellar vacation? Consider visiting Kepler-16b, a world in a binary star system. In fact Kepler-16b is the first discovered circumbinary planet. It was detected in a wide 229 day orbit around a close pair of cool, low-mass stars some 200 light-years away. The parent stars eclipse one another in their orbits, observed as a dimming of starlight. But Kepler-16b itself was discovered by following the additional very slight dimming produced during its transits. Like sci-fi planet Tatooine of Star Wars fame, two suns would set over its horizon. Still, Kepler 16b is probably not a Tatooine-like terrestrial desert world. Instead, Kepler 16b is thought to be a cold, uninhabitable planet with about the mass of Saturn and a gaseous surface ... so plan to dress accordingly. Or, choose another Visions of the Future vacation destination. For image credit and copyright guidance, please visit the image websitehttp://antwrp.gsfc.nasa.gov/apod/ap160220.html
Just like many organizations, the style and logos can change over time. You are probably most familiar with our “meatball” logo. No, unfortunately this does not refer to the delicious food. This logo (below) is our most popular symbol, and dates back to 1959.
But, we’ve also had other insignia that represented our organization throughout the years.
The “worm” logo (below) was used by the agency from 1975 until 1992. The organization wanted to create a more “modern” logo, which resulted in the unique type style of the “worm” logo.
Even though this logo was retired in 1992, the Graphics Standards Manual is still available online HERE.
You can also read up about the emblems, logos and insignia used by NASA throughout the years in a new e-Book available for free HERE.

Each month, we highlight a different research topic on the International Space Station. In August, our focus is biological research. Learning how spaceflight affects living organisms will help us understand potential health risks related to humans on long duration missions, including our journey to Mars.
Cells, microbes, animals and plants are affected by microgravity, and studying the processes involved in adaptation to spaceflight increases our fundamental understanding of biological processes on Earth. Results on Earth from biological research in space include the development of new medications, improved agriculture, advancements in tissue engineering and regeneration, and more.
Take a look at a few of the biological research experiments performed on space station:
Biomolecule Sequencer
Living organisms contain DNA, and sequencing DNA is a powerful way to understand how they respond to changing environments. The Biomolecule Sequencer experiment hopes to demonstrate (for the first time) that DNA sequencing is feasible in an orbiting spacecraft. Why? A space-based DNA sequencer could identify microbes, diagnose diseases and understand crew member health, and potentially help detect DNA- based life elsewhere in the solar system.
Ant-stronauts
Yes, ant-stronauts…as in ants in space. These types of studies provide insights into how ants answer collective search problems. Watching how the colony adapts as a unit in the quest for resources in extreme environments, like space, provides data that can be used to build algorithms with varied applications. Understanding how ants search in different conditions could have applications for robotics.
TAGES
The TAGES experiment (Transgenic Arabidopsis Gene Expression System) looks to see how microgravity impacts the growth of plant roots. Fluorescent markers placed on the plant’s genes allow scientists to study root development of Arabidopsis (a cress plant) grown on the space station. Evidence shows that directional light in microgravity skews root growth to the right, rather than straight down from the light source. Root growth patters on station mimic that of plants grown at at 45% degree angle on Earth. Space flight appears to slow the rate of the plant’s early growth as well.
Heart Cells
Spaceflight can cause a suite of negative health effects, which become more problematic as crew members stay in orbit for long periods of time. Effects of Microgravity on Stem Cell-Derived Cardiomycytes (Heart Cells) studies the human heart, specifically how heart muscle tissue contracts, grows and changes in microgravity. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions.
Medaka Fish
Chew on these results…Jaw bones of Japanese Medaka fish in microgravity show decreased mineral density and increased volume of osteoclasts, cells that break down bone tissue. Results from this study improve our understanding of the mechanisms behind bone density and organ tissue changes in space.
These experiments, and many others, emphasize the importance of biological research on the space station. Understanding the potential health effects for crew members in microgravity will help us develop preventatives and countermeasures.

There are some that fly an airplane, and there are those who become one with the air and machine. Sad news today. Bob Hoover passed away at the age of 94. A stick and rudder pilot for the ages. I met and got an autograph back in the late 1990s. A class act all the way. Mr. Hoover brought flying to an artistic level. RIP Mr. Hoover, you took to the skies, dazzling and inspiring so many. We mourn his loss, and celebrate a life.

What strange world is this? Earth. In the foreground of the featured image are thePinnacles, unusual rock spires in Nambung National Park in Western Australia. Made of ancient sea shells (limestone), how these human-sizedpicturesque spires formed remains unknown. In the background, just past the end of the central Pinnacle, is a bright crescent Moon. The eerie glow around the Moon is mostly zodiacal light, sunlight reflected by dust grains orbiting between the planets in the Solar System. Arching across the top is the central band of our Milky Way Galaxy. Many famous stars and nebula are also visible in the background night sky. The featured 29-panel panorama was taken and composed last September after detailed planning that involved the Moon, the rock spires, and their corresponding shadows. Even so, the strong zodiacal light was a pleasant surprise. Image Credit: Michael Goh
Our InSight mission will place a fixed science outpost on Mars to study its deep interior. Findings and research from this project will address one of the most fundamental questions we have about planetary and solar system science – How in the world did these rocky planets form?
By investigating the interior structure and processes of Mars, the InSight mission will gain a better understanding of the evolutionary formation of planets, including Earth.
InSight will record Mars’ vital signs to learn more about the planet, including:
Seismic Activity:
A seismometer will be used to record the seismic activity on Mars. This will give us information on the crust, mantel and core; and the relationship between them.
Temperature:
A heat flow probe will be used to take Mars’ temperature and determine the change over the course of a full Martian year.
Reflexes:
By looking at how the rotation of Mars wobbles, we will better understand what the core size may be and its composition.
Launch for the InSight mission is scheduled for March 2016, and even though you can’t physically travel with the lander, you can send your name to the Red Planet onboard. Make sure to submit your name before Sept. 8!
