Space Exploration | Universe Today

JPL has a fun article on their website detailing what future robotic exploration might entail: an armada of robots could one day fly above the mountain tops of Saturn's moon Titan, cross its vast dunes and sail in its liquid lakes. This is the vision of Wolfgang Fink, from the California Institute of Technology. He says we are on the brink of a great paradigm shift in planetary exploration, and the next round of robotic explorers will be nothing like what we see today.

I very much enjoyed chatting with Buzz Aldrin a couple of weeks ago, for some stories leading up to the 40th anniversary of the July 20, 1969 Apollo 11 landing on the moon. I found him honest, personable and generous with his time.

But when his publicist offered to send a copy of his new book, "Magnificent Desolation," I didn't set my expectations too high. I didn't know what to make of an autobiography by a retired Air Force pilot and astronaut. Doesn't that history put the "Rocket Hero" pretty squarely in the category of techie or a jock — a non-writer type?

Well, color me impressed. The book arrived late last week, and I turned the last page this morning — looking for more to read!

Peter Smith feels pretty certain we'll be finding life on Mars within the next decade. 

Smith, the University of Arizona professor who led NASA's Phoenix Mars Mission, made his predictions to a spellbound audience during a lecture at the University of Delaware earlier this month, and he discussed his ideas by phone on Thursday. He carries a "sense of optimism" about finding life on Mars, he said, because of the tantalizing clues Phoenix sent to Earth.

"Finding life on Mars would be one of the great discoveries of all time," he said. "We're not that far away. The next mission could be the one."

The Senate Budget Committee has given the green light to fund NASA's shuttle program past the end of 2010, when the program is set to retire.

But NASA isn't asking for an extension.

Florida Sen. Bill Nelson requested the $2.5 billion provision, which was included in the broader five-year spending plan that passed committee Monday afternoon. His office argues that launching nine missions in 18 months puts too much pressure on the agency, and could compromise safety.

How ironic. Not content with searching for life on Mars, the Russian space agency and the US-based Planetary Society will soon be sending terrestrial life to the Martian moon Phobos. The mini-interplanetary travellers will consist of bacteria, spores, seeds, crustaceans, insects and fungi. Why? To see how biological life, in various forms, deals with space travel spanning three years.

So if you thought that a human (or monkey) would be the first of Earth's ambassadors to land on Mars or one of its moons, you'd be very mistaken…

A new type of lunar robots is being designed which could help prepare locations on the Moon for human outposts and landing pads. With supervised autonomy, small robots the size of riding mowers and weighing 300 kg or less could prepare a site in about 6 months, says a new study by Astrobotic Technology Inc. in cooperation with Carnegie Mellon University’s Robotics Institute.

Anyone else having visions of Wall-E on the Moon?

It reads like the annual progress report from my first year in university. He lacks direction, he's not motivated and he has filled his time with extra-curricular activities, causing a lack of concentration in lectures. However, it shouldn't read like an 18 year-old's passage through the first year of freedom; it should read like a successful, optimistic and inspirational prediction about NASA's future in space.

What am I referring to? It turns out that the Houston university where President John F. Kennedy gave his historic "We go to the Moon" speech back in 1962 has commissioned a report, recommending that NASA should give up its quest for returning to the Moon and focus more on environmental and energy projects. The reactions of several astronauts from the Mercury, Apollo and Shuttle eras have now been published. The conclusions in the Rice University report may have been controversial, but the reactions of the six ex-astronauts went well beyond that. They summed up the concern and frustration they feel for a space agency they once risked their lives for.

At the end of the day, it all comes down to how we interpret the importance of space exploration. Is it an unnecessary expense, or is it part of scientific endeavour where the technological spin-offs are more important than we think?

I've been meaning to put together an article highlighting the best space images of 2008, but I see time is slowly slipping away from me to get this out before 2008 turns into 2009. However, I'm in luck! A few people have already done the work for me, and so I'll just link to them. First, of course, is Phil Plait over at the Bad Astronomy Blog, who does his annual Top Ten Astronomy Pictures, and this year's choices by the BA were excellent. Next, Dave Mosher over at Discovery Space has just put together a slideshow of his picks for the Best Space and Astronomy Pictures of 2008. Nice job, Dave! And this just in (update 8:10 pm) — Emily Lakdawalla at the Planetary Society Blog has a great selection of The Year in Pictures 2008. Thanks Emily!

There are more links below, but I know if I would have done a list myself, the image above would have been my #1 pick. This shot by the Mars Reconnaissance Orbiter's HiRISE Camera of the Phoenix lander descending through Mars' atmosphere is truly outstanding. It's an unbelievable shot, and I'll always remember how my jaw dropped in disbelief when I first saw it.

And now back to everyone else's best pics of 2008 lists:

Two upstart commercial space companies have been awarded contracts by NASA for commercial cargo resupply services to the International Space Station. SpaceX, also known as Space Exploration Technologies received a contract for $1.6 billion while Orbital Sciences Corp. of Dulles, Va. has a contract valued at $1.9 billion. NASA has ordered 12 flights from SpaceX and eight from Orbital. In October, at this year's International Symposium for Personal and Commercial Spaceflight, SpaceX Vice President of Marketing and Communications Diane Murphy said that the six- year-old company has it in their sights to be able to fly to the space station by 2009. For now, the contract is for cargo only, however SpaceX's Dragon capsule and Falcon 9 rocket are human rated, and would be capable of delivering up to 7 crew members to the station. The Dragon could also be used as an escape vehicle. If SpaceX and Orbital can be successful in cargo re-supply, it could pave the way for a potential solution to the gap between the shuttle retirement in 2010 and when the Constellation program would be ready to fly, hopefully by 2015.

A coalition of leaders working on the concept of a space elevator has joined forces to form the International Space Elevator Consortium (ISEC). The new independent group is designed to promote standards and foster research relating to the construction of an Elevator to Space at the global level. Founding members of ISEC include the Spaceward Foundation, the Space Elevator Reference, the Space Elevator Blog, EuroSpaceward and the Japan Space Elevator Association. Heading the new organization is Ted Semon of the Space Elevator Blog, who will serve as president. Michael Laine, president of the space elevator company Liftport is excited about the consortium. "I think it’s a great thing," he said. "This has been in the works for months, and the need to bring the different organizations under one roof has been long overdue. All five of the major organizations have been acting independently, which made sense in the beginning, but now we need coordination and cooperation."

The Apollo 8 mission was a seminal moment not in only the history of spaceflight, but in human history as well. The mission came during a time when the US and the world were divided by war and racial issues. It's been said that Apollo 8 "saved" 1968 from being an otherwise divisive and disheartening year, and because of the success of the mission – in terms of both technical and philosophical matters — the Apollo 8 crew of Frank Borman, Jim Lovell and Bill Anders were named "Men of the Year" by Time Magazine. Apollo 8 was the first human mission to orbit the moon, but it wasn't supposed to be. And the mission was responsible for one of the most iconic images of our time.

Communication with spacecraft is vital for NASA, and since the World Wide Web has enabled easy, reliable and quick contact for people around the world, the space agency decided to model a new deep space communication system on the internet. A month-long test of this "Interplanetary Internet" was successfully conducted by transmitting dozens of images to and from the EPOXI spacecraft, now about 20 million miles from Earth. The system uses software called Disruption-Tolerant Networking, or DTN created by a partnership between NASA and Google vice president Vint Cerf. "This is the first step in creating a totally new space communications capability, an interplanetary Internet," said Adrian Hooke, team lead and manager of space-networking architecture, technology and standards at NASA Headquarters in Washington.

In an initiative energized by Google Vice-President and Chief Internet Evangelist Vint Cerf, the International Space Station could be testing a brand new way of communicating with Earth. In 2009, it is hoped that the ISS will play host to an Interplanetary Internet prototype that could standardize communications between Earth and space, possibly replacing point-to-point single use radio systems customized for each individual space mission since the beginning of the Space Age.

This partnership opens up some exciting new possibilities for the future of communicating across vast distances of the Solar System. Manned and robotic space craft will be interconnected via a robust interplanetary network without the problems associated with incompatible communication systems…
