Video Caption: The Hubble Space Telescope has captured even more evidence of water vapor plumes on Jupiter’s icy moon Europa. The probable plumes appear to be repeating in the same location and correspond with a relatively warm region on Europa’s surface observed by the Galileo spacecraft.
WASHINGTON (NASA PR) — Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope.
In the papers, Cassini scientists announce that a form of chemical energy that life can feed on appears to exist on Saturn’s moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter’s moon Europa.
“This is the closest we’ve come, so far, to identifying a place with some of the ingredients needed for a habitable environment,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at Headquarters in Washington. ”These results demonstrate the interconnected nature of NASA’s science missions that are getting us closer to answering whether we are indeed alone or not.”
PASADENA, Cailf. (NASA PR) — NASA’s upcoming mission to investigate the habitability of Jupiter’s icy moon Europa now has a formal name: Europa Clipper.
The moniker harkens back to the clipper ships that sailed across the oceans of Earth in the 19th century. Clipper ships were streamlined, three-masted sailing vessels renowned for their grace and swiftness. These ships rapidly shuttled tea and other goods back and forth across the Atlantic Ocean and around globe.
WASHINGTON (NASA PR) — Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.
The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice.
WASHINGTON (NASA PR) — NASA will host a teleconference at 2 p.m. EDT Monday, Sept. 26, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa.
NASA officials have been providing updates this week on agency programs and missions during the 2016 Small Satellite Conference and the CubeSat Workshop that preceded it. I have pulled together summaries of their presentations drawn from Twitter. Information has come from the following Tweeters:
The House Appropriations Committee is marking up a FY 2017 spending bill today that would boost NASA’s spending by $215 million to $19.5 billion dollars. The amount is roughly $500 million more than the $19 billion requested by the Obama Administration.
Appropriators have zeroed out money for NASA’s Asteroid Redirect Mission (ARM), instead instructing the space agency to focus on lumar missions applicable to sending astronauts to Mars.
The House Appropriations Committee has released a spending bill that would give NASA a budget of $19.5 billion for fiscal year 2017, which is $500 million above President Barack Obama’s request. The measure boosts spending for exploration and science programs. Details from the measure are below:
Exploration: $4.183 billion
Orion: $1.35 billion
Space Launch System: $2 billion
Exploration Upper Stage: $250 million of SLS funding
Exploration Ground Systems: $429 million
Exploration R&D: $404 million
Science: $5.597 billion
James Webb Space Telescope: $8 billion cost cap
Jupiter Europa orbiter and lander: $260 million
Use of the Space Launch System as the launch vehicle or vehicles for the Jupiter Europa mission plan
launch of the Jupiter Eruopa orbiter launch no later than 2022 and a lander launch no later than 2024.
Space Operations: $4.89 billion Space Technology: $739.2 million Aeronautics: $712 million Education: $115 million Safety, Security & Mission Services: $2.835 billion Construction & Environmental Compliance and Restoration: $398 million Office of Inspector General: $38.1 million
NASA’s Innovative Advanced Concepts (NIAC) program recently selected 13 proposals for Phase I awards. Below is one from Masahiro Ono of NASA’s Jet Propulsion Laboratory.

In Jules Verne’s classic science fiction, Journey to the Center of the Earth, Professor Otto Lidenbrock and his company descend into an Icelandic volcano to explore it in the name of science, discover a vast subterranean ocean among other unexpected wonders, and must resiliently survive the experience to complete their mission. This is exactly what we want to do in reality on Europa and Enceladus.
Congress has been a lot more excited than NASA about a mission to explore Jupiter’s frozen moon Europa, giving the agency more funds than it has requested for a mission that will be much more ambitious than originally planned.
NASA would received $19.3 billion in FY 2016 under an Omnibus spending measure unveiled early Wednesday by Congress. The amount would be $1.27 billion more than last year and $756 million above the amount requested by President Barack Obama.
The Commercial Crew Program would receive “up to $1.24 billion,” which is the amount requested by the Administration. It would mark the first time that Congress has fully funded the program if it receives the total amount. It is not clear exactly what the phrase “up to” means.
Just about every other major program would receive a boost in spending, including the Space Launch System, Orion deep space vehicle, International Space Station, and the Science and Space Technology programs.
