WASHINGTON (NASA PR) — Want to grab a front row seat to the future? If so, look no further than the NASA Innovative Advanced Concepts (NIAC) program to gain that opportunity.
NIAC is home base and incubator of cutting-edge, innovative and technically credible advanced concepts…ideas that could one day change the possible in aeronautics and space.
Video Caption: What would a submarine to explore the liquid methane seas of Saturn’s Moon Titan look like? This video shows one submarine concept that would explore both the shoreline and the depths of this strange world that has methane rain, rivers and seas! The design was developed for the NASA Innovative Advanced Concepts (NIAC) Program, by NASA Glenn’s COMPASS Team, and technologists and scientists from the Applied Physics Lab and submarine designers from the Applied Research Lab.
WASHINGTON (NASA PR) — NASA has selected 12 proposals for study under Phase I of the NASA Innovative Advanced Concepts (NIAC) Program, which aims to turn science fiction into fact through pioneering technology development.
The selected proposals cover a wide range of imaginative concepts, including:
a submarine to explore the methane lakes of Titan;
using neutrinos to perform measurements for the icy moons of the outer planets; and,
a concept to safely capture a tumbling asteroid, space debris, and other applications.

NSC PR — TILLAMOOK, OR — Near Space Corporation (NSC), a leading innovator of terrestrial and planetary exploration balloon technology, has received a Phase Two NASA Small Business Innovative Research (SBIR) award to fund work that will help enable future airborne exploration of Saturn’s moon Titan. NSC’s winning proposal was among 85 selected from a total pool of 428 submissions.
Climate change and suborbital spaceflight
The same day that commercial spaceflight supporters were celebrating the development of Spaceport America, a new study concluded that suborbital flights that facility will host could alter the planet’s climate. Jeff Foust examines the latest research and some of the issues associated with the study.
The mysteries of Titan
Thirty years ago this week Voyager 1 made the first close flyby of Titan, Saturn’s largest moon and one of the most intriguing worlds in the solar system. Andrew LePage recounts the research into Titan and the planning that led up to that encounter.
Space solar power’s Indian connection
As the United States and India seek closer ties, should space-based solar power be on the agenda? Jeff Foust reports on developments in that field, including a new joint initiative supported by a former Indian president.

NASA MISSION UPDATE
Planetary scientists have been puzzling for years over the honeycomb patterns and flat valleys with squiggly edges evident in radar images of Saturn’s moon Titan. Now, working with a “volunteer researcher” who has put his own spin on data from NASA’s Cassini spacecraft, they have found some recognizable analogies to a type of spectacular terrain on Earth known as karst topography. A poster session today, Thursday, March 4, at the Lunar and Planetary Science Conference in The Woodlands, Texas, displays their work.
Bold New Missions to Jupiter and Saturn Planned
Space.com
NASA and the European Space Agency (ESA) are pushing ahead with proposals to send ambitious missions to explore Jupiter, Saturn and the many moons that circle both planets, the two space agencies announced Wednesday.
Data collected during several recent flybys of Titan by NASA’s Cassini spacecraft have put another arrow in the quiver of scientists who think the Saturnian moon contains active cryovolcanoes spewing a super-chilled liquid into its atmosphere. The information was released during a meeting of the American Geophysical Union in San Francisco, Calif.
“Cryovolcanoes are some of the most intriguing features in the solar system,” said Rosaly Lopes, a Cassini radar team investigation scientist from NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “To put them in perspective – if Mount Vesuvius had been a cryovolcano, its lava would have frozen the residents of Pompeii.”
“Athena Coustenis, an astrophysicist and planetologist with the Paris Observatory, is helping draft a plan to send a hot air balloon to Titan, as well as an orbiting spacecraft and a surface probe. Called TSSM – the Titan and Saturn System Mission – this three-tiered approach to exploration could shed more light on the still-mysterious moon.”
“’Titan is the best place to go with a balloon because of the atmosphere,’ says Coustenis. Although the atmosphere of Titan is filled with a smoggy orange hydrocarbon haze, it is primarily composed of nitrogen – just like Earth’s. In fact, Astrobiologists think Titan’s atmosphere may be quite similar to how the Earth’s was billions of years ago, before life on our planet generated oxygen.”
