SpaceDev Dream Chaser: Let's Get it Straight


Jim Benson dropped us a line last week, suggesting we might have been unfair in pointing out he has no hardware despite a plan to start sending paying customers to space in a few short years.

Fair enough. As he points out no one else does either, except SpaceShip One, which utilizes a hybrid rocket engine designed by SpaceDev, the same company responsible for developing Benson's SpaceDev Dream Chaser.


While the SpaceDev Dream Chaser project has no publicly displayed hardware, it certainly does have an impressive lineage: Vertical take-off and landing capability has been repeatedly successfully tested by NASA; It's lifting body design has been successfully tested by the Soviet Buran program; and the fact SpaceDev rockets have a very good success rate.


There are currently at least a half dozen commercial sub-orbital space tourism companies promising flights will begin in a few years or so. Of them all, Virgin Galactic is probably closer than anyone else, simply because they are using an already proven method for space insertion.

Benson Space Co. and the SpaceDev Dream Chaser are a close second place simply because of the proven concepts behind their project.


We stand slightly corrected, though still firm believers in the adage "the proof is in the pudding"...

Tooth Regeneration Success!


CNN is reporting that Japanese scientists have successfully grown new teeth in a mouse using only a single original cell. And it wasn't a stem cell.

The original story appeared in Nature Methods.

This success puts us further on the path to growing replacement organs from a patients own cells. The ability to do this means a better alternative for astronauts on deep space missions who become seriously ill or injured.

Heard The News? ISS Crew Sets New Record--Pass It On


NASA Astronaut Michael Lopez-Alegria set a new U.S. spacewalking record during their third EVA in little more than a week. The stepped-up pace of work is meant to help bring the station to a point where more scientific research can be conducted, the crew can be expanded and new labors on other space-related missions can be conducted. If all goes well, by this time next year there will be six astronauts on board, rather than the three-person crew which has manned the station for several years now.


The new U.S spacewalking record of 58 hours 32 minutes is still a long ways from the all-time record set by Russian Cosmonaut Anatoly Solovyoz of 82 hours. But for the Americans it is a step in the right direction...

Lost Amid the Turmoil: Ulysses Conducts Solar Pole Mission


While most of the nation searched for "astronaut diapers" and 'lust in space', NASA and ESA scientists were titillated by data from yesterday's solar southpole flyby being conducted by the Ulysses spacecraft.

For the third time since its launch in 1990, Ulysses has crossed the south pole of the Sun in an effort to provide data on an area we know very little about. The magnetic field in this area is different, Solar Wind comes from here, and strangely enough (according to data retrieved during a previous flyby of the area) the surface temperature in this area is different.


Scientists are excited about the questions they may have answered following this trip but also the new questions they will develop because of it...

Dream Chaser Developer Still Making Headlines, Despite Not Having Hardware


Brian Emmett, the software consultant who gave up the free suborbital spaceflight with Virgin Galactic he won from Oracle Corp. (valued at $138,000) is still making headlines, with a little help from Benson Space Co. founder, Jim Benson.

Granted the SpaceDev Dream Chaser is a real concept, with an impressive heritage of success,it is also true that at this time no hardware has been displayed, much less tested. Suborbital flights are not scheduled until late 2008, and no commercial flights until 2010, but the lack of an actual craft for shake-out means anything could happen between now and then; multiple delays are nearly guaranteed.

However, credit Benson with keeping the company name in the news, by offering Emmett a job and a free ticket to ride one of the first flights, provided he write about his experiences during testing and training.
Benson, with 30 years experience as a successful technology entrepreneur, knows his way around the business of making money, so leave it to him to take advantage of good PR...

Endeavor Returning After Three-Year Overhaul


Florida Today is reporting NASA crews are hard at work reconstructing shuttle Endeavor following a three-year overhaul in the wake of the Columbia disaster. It will roll out to the launch pad on May 25, slated for liftoff to the International Space Station on June 29. It will be NASA's 119th shuttle mission. It's payload is small section of the ISS truss.


Perhaps its most precious cargo, however, will be astronaut educator, mission specialist Barbara Morgan.
Morgan will be NASA's first "educator astronaut", following in the footsteps of her successor, Christa McAuliffe, killed with six other astronauts in the Challenger disaster of 1986.
McAuliffe was to teach two lessons during her trip; It is hoped Morgan will provide NASA with the tools needed to better connect its mission for space exploration with schoolchildren everywhere...

Experimental Lunar Lander for Sale on eBay


An experimental Lunar Lander named Lauryad I is for sale right now on eBay. Buy it now for $199,999.00.


The Lauryad I designers and builders intend to compete in this year's X-Prize Cup, Lunar Lander Challenge. Winning bidder will own the ship outright and be entitled to half its earnings (if any) from the contest.

The craft is named for a ship from author Vanna Bonta's FLIGHT novel.


Chief engineer on the Lauryad I project, Allen Newcomb, also worked on Burt Rutan's SpaceShip One. This may or may not give him an edge in the lander competition, though Armadillo Aerospace has already shown great success with its entry, nicknamed Pixel.


Regardless of the outcome of the Challenge, the buyer of Lauryad I will still be a winner in the eyes of space enthusiasts everywhere...

Discovery Astronaut Charged with Attempted Kidnapping




CNN is reporting that NASA astronaut Lisa Marie Nowak, mission specialist aboard Discovery shuttle flight STS-116 last July, and the first Italian-American woman in space, has been arrested and charged with the attempted kidnapping of a romantic rival.
According to reports Nowak, married with three children, was vying with another woman for the affection of astronaut William A. Oefelein, pilot aboard shuttle flight STS-116.
Police say Nowak followed the woman, Colleen Shipman, from Texas to Florida, then accosted her in the parking lot of Orlando International Airport. During a search of Nowak's vehicle police discovered a BB gun, steel mallet and folding knife; rubber gloves and garbage bags; maps to Shipman's home and love letters to Oefelein.
Police also say Nowak told them she only intended to scare Shipman into talking to her about the relationship issue; she admitted having some sort of relationship beyond a working one with Oefelein, though she declined to be more specific.
The Orlando Sentinel has a copy of the arrest affidavit here.

China Space Successes Continue Unabated


Fresh from their recent success shooting down an orbiting satellite with a spear-tipped missile, China successfully launched another Beidou navigation satellite last Friday.

When completed sometime in the next few years, the Beidou, or 'Big Dipper' satellite system, will provide an independent Chinese satellite navigation system.


The Beidou system has been in development for nearly five decades, and will provide all-weather communication/navigation data for most of East Asia. Chinese scientists have been developing the system slowly, expanding and improving as funds have become available. China's recent economic growth has now provided them with the means to make it happen.


Friday's launch also further showcased the nation's successful Long March rocket launch system, also responsible for lifting the Shenzhou spacecraft. Another wildly successful Chinese space program...

Atlantis Prepped for Flight


Space Shuttle Atlantis is scheduled to be moved to the vehicle assembly building on Wednesday, where it will be attached to its external fuel tank and prepped for flight. Mission STS-117 is scheduled to lift-off March 15 and head straight for the International Space Station where the crew will install a 14 meter truss and re-arrange some solar arrays.


The crew of STS-117 has been prepping for some time and fully intends to make the most of their time in space, completing their mission on time and without mishaps. Although installing trusses and solar arrays may seem 'old hat', nothing is ever quite as easy in space as it seems to be during training on the ground.


Godspeed...

ISS Residents DIY; Set Spacewalking Records


CNN has a nice story about the record setting spacewalk of International Space Station resident astronaut Sunita Williams. This week Williams became the first female U.S. astronaut to spend more than 21 hours of spacewalking. Astronaut Michael Lopez-Alegria is expected to set a new U.S record for men-in-space, later this month, when he surpasses 58 hours.


Despite these amazing records, what truly amazes us at SBA is that Americans still act as if there is a battle of the sexes going on. If you ask us, that type of thinking is so 20th Century...

Lockheed Martin Gets Keys to the Future (and $8 Billion)


According to this story in Florida Today, on Tuesday, NASA officials handed over the keys to the vehicle assembly building to be used by Lockheed Martin engineers designing the new Orion space vehicle. Though the company received an $8 billion contract for the project, the state of Florida also offered them $45 million to refurbish the outdated (though historically significant) Operations & Checkout Building, which will house the new spacecraft.


The O&C Building is the site where the Apollo spacecraft and Skylab were built, but it had long since fallen into disrepair. The new deal means the building will not be sold-off to developers (as had been planned) and will continue to play a vital role in the nation's space program, as it always has.


General Contractors in Space!


MSNBC.com has a nifty story detailing plans to build a lunar community in the 2020's, and the steps currently being taken to make that dream a reality.


Chief among them is understanding the tools we will need and the materials we will have to work with. Last year's discovery that microwaving moon dirt creates something similar to concrete has become a plan to build rovers which will do the job automatically; inflatable modules once tossed around as a possibility have become the choice of future designers and companies like Bigelow Aerospace are already putting some of those designs to good use in orbit.


But perhaps the most important part of any future lunar community will be the men and women of all nations who go there to work, live and carve out a future home for humanity. But truth be told these astronauts, though rigorously trained in all the skills needed to survive such a harsh environment, will be not much more than general contractors, building the subdivisions of the future...

ISS Has Full Slate for 2007


In what is its most ambitious schedule yet, the crew of the International Space Station in 2007 will undertake more spacewalks, install more hardware and expand the size of their living quarters to create a space-based laboratory that would make DS9 Commander Benjamin Sisko proud.

Star Trek analogies aside, if NASA and its cadre of international partners are successful, by 2008 the station will be much larger, have more power and be able to conduct more science than ever before. More space, means more room for additional crew, and a reason for the first ISS spacecraft developed by the European Space Agency, the Automated Transfer Vehicle. Designed as a resupply craft, the ATV provides yet another means of getting supplies to the station without the need for the Shuttle or Progress spacecraft.

Japan too intends to build its own resupply ship for its Kibo laboratory which will be installed later this year.

In addition to this news, NASA this week signed agreements with two more private space launch companies to possibly provide future ships for flights to and from ISS though neither company yet has a completed craft...

Sea Launch Statement Says Investigation Has Begun


Following the dramatic explosion and destruction of its Zenit-3SL rocket and the NSS-8 spacecraft it carried, Sea Launch has released a statement claiming its floating Odyssey Launch Platform, though sustaining limited damage is seaworthy and supporting a full crew.


It also said it has received the full support of its customers and the "insurance community" regarding its track record of success and safety.


What exactly caused the calamity has yet to be determined, though a story at Spaceflight Now seems to indicate the rocket fell over immediately after engine ignition...

Yet Another Flying Car


The race is on to build the flying car of tomorrow, as yet another contender has joined the fray.
CNN is reporting that Urban Aeronautics, an Israeli company, hopes to have a marketable version of its first commercial flying vehicle on the road (so to speak) by 2010.

Called the X-Hawk, the vehicle is being designed for use as an emergency transport vehicle for urban rescue missions. Like most flying cars currently under design the significant difference between this type of vertical-takeoff-and-landing vehicle and, say, a helicopter, will be its enclosed rotors, making power lines and tree tops a non-issue when it comes to maneuvering.


It remains to be seen which of the many planned flying cars will be the first to see flight. Among the many contenders: Moller Skycar; Transition, by Terrafugia, Inc.; or perhaps the less futuristic-looking AirScooter being built by AirScooter Corp.


There are many more dedicated engineers and inventors looking to make the best of the forthcoming Small Aircraft Transportation System, so it's still anybody's game...
