Many planetary scientists believe that Jupiter’s moon Europa is our solar system’s best contender to share Earth’s distinction of harboring life. Evidence gathered by the Voyager and Galileo spacecrafts suggests Europa contains a deep, possibly warm ocean of salty water under an outer shell of fissured ice. In a paper published in the July 2007 […]
Some proponents of human missions to Mars say we have the technology today to send people to the Red Planet. But do we? Rob Manning of the Jet Propulsion Laboratory discusses the intricacies of entry, descent and landing and what needs to be done to make humans on Mars a reality. There’s no comfort in […]
STS-115 is an ambitious mission that returns the focus of human spaceflight to building the International Space Station, bringing new capabilities to the ISS. While a song by John Lennon asserts that revolution will bring power to the people, it will be a new set of solar arrays and its ability for rotation that will […]

With the release NASA’s 2007 budget request, it was clear that the productive science programs will be paying the price for the new Vision for Space Exploration, returning humans to the Moon and then sending them on to Mars. Many programs […]
Paul Verhage has some pictures that you’d swear were taken from space. And they were. Amateur Radio High Altitude Ballooning allows individuals to launch functioning satellites to “near space” at a fraction of the cost of traditional rocket launch vehicles. Paul’s balloons have been as high as 35 km, and the photographs he’s taken are out of this world.
The centerpiece of NASA’s Vision for Space Exploration is the new spacecraft that will carry astronauts to the moon, Mars and beyond. Jeff Hanley, appointed as Constellation Program manager in October, discusses the development of the new Crew Exploration Vehicle, the role of the International Space Station, and the path of the ‘Vision.’
The Mars Exploration Rovers have unquestionably been one of NASA’s most exciting and successful missions to date. The projects scientific principal investigator, Dr. Steve Squyres of Cornell University has written a candid and fascinating new book about the mission. Roving Mars: Spirit, Opportunity, and the Exploration of the Red Planet offers an inside look at the journeys the rovers have taken; not only their captivating treks across Mars, but the surprisingly circuitous and difficult route they took from inception to development and launch.
The New Horizons mission to Pluto has been called ?The First Mission to the Last Planet,? and it?s the first mission to venture to a ?new? planet since the Voyager missions nearly 30 years ago. While New Horizons includes proven technology and a superior launch vehicle, it could be considered to be a ?throw-back? mission. Some of the scientific instruments on board are named after characters from the 1950?s television show, ?The Honeymooners,? and the project?s Principal Investigator, Dr. Alan Stern of the Southwest Research Institute, says the mission makes him feel like he?s back in the heyday 1960?s or 1970?s of space exploration because this mission is all about exploring planets for the first time.
