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.

Commercial Space & Ocean Worlds: NASA Co-Op #3 Week 14
Did you know that at least one human has inhabited the International Space Station over 16 years?!
NASA even has a Cumulative Crew Time on Orbit clock. Frequent flyers of this blog are familiar with the giant space lab orbiting the Earth every 90 minutes, however, even some of the public within a 20 mile radius of Johnson Space Center think NASA has shut down! It's up to myself, NASA full-timers, NASA interns and the science enthused to educate the public about the continuing efforts in space exploration.
International Space Station (ISS) Program Manager Kirk Shireman hosted an all hands for NASA employees to share about achievements and future goals. NASA is leading the commercialization of space by. The media often portrays NASA as fretting space commercialization when in reality NASA is fueling it. NASA has contracted SpaceX and Orbital ATK to deliver cargo to ISS every couple of months as commercial resuppliers. Launch of ATK April 18th 9:30am-10:30am CT. Boeing and SpaceX are being contracted by NASA to develop the Commercial Crew Vehicles to transport astronauts from Earth to ISS and back. The Commercial Crew Program enables manned launches from American soil. Additionally ISS is working toward attaching station nodes built by private space companies that deploy CubeSats. NASA thinks of the private and public space company research and device developers as customers. NASA is working on making space more accessible to its "customers".
Graduate School Advice
A Co-Op student leader coordinated a graduate panel with folks with NASA experience that also completed grad school. These are some helpful anonymous quotes from the panel...
“So when you roll into my office and say you want to be an astronaut I need a PhD, remember these are seven to eight years of your life”.
“How long it takes depends on how long it takes to do new science”.
“How many papers does it take to graduate? Okay. Spit in your hand and shake”.
Student: I want to get a degree in something very different than undergrad.
Panel member: “You can do anything”.
“Most people are human.”
“The answers aren’t in the back of the book once you start full-time.”
Ocean Worlds in Our Solar System
Evidence of giant water plumes observed on one of Saturn's moon Enceladus and one of Jupiter's Europa has been found. This exploration started in the 1990s when Galileo space craft orbited Jupiter and its moons. The magnetic signature detected on Europa suggests ocean like currents underneath its icy shell. During a 2005 Cassini performed an Enceladus fly by and spotted huge plumes were observed. Recently data from these mission have been analyzed and conclusions have been reached.
Terrestrial oceans have hydro thermal activity feeding life deep 1000s of meters below the ocean. Plumes spotted on extraterrestrial worlds are believed to produce "300 pizzas per hour of energy" in calories. "The statistics tell us that plumes are real by full sigma results". However, Hubble has reached its max to detect these plumes on Europa so scientists cannot be certain yet. Bill Sparks from Goddard expanded on the uncertain of Europa's plumes, "It's not completely unequivocally but in my mind the pendulum has swung from cation to optimism. The evidence is growing. The fact we have saw a repeated the exact same location. That's one of the gold standards for dealing with a repeat phenomenon. It's not proof because we are right at the limit of what Hubble can do." He shared it is evidence rather than proof because spectrometer readings, movies and maps have been taken of Enceladus is high definition compared to the smudge of low resolution observation made by Hubble's max capacity.

This week at NASA.
NASA commercial cargo provider Orbital ATK is targeting its seventh commercial resupply services mission to the ISS for 10:11 a.m. CDT Tuesday, April 18. Coverage of the launch begins at 9 a.m. on NASA TV.
lone explorer from Earth around Saturnian system
An awe-inspiring journey captured by Cassini in the 13 years it’s been observing the Saturnian system. It is humbling and breathtaking to see the spacecraft taking images of the glowing and sun-eclipsing Saturn.
Preemptively, in few hours, Cassini will burn up and disintegrate like a meteor as it enters the Satrun’s atmosphere at 70,000 miles per hour.
It is truly a privilege to be part of NASA’s JPL to explore the grandeur of the universe.
