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.
