NEW ROCKET TECHNOLOGY COULD CUT MARS TRAVEL TIME

An agreement to collaborate on development of an advanced rocket technology that could cut in half the time required to reach Mars, opening the solar system to human exploration in the next decade, has been signed by NASA's Johnson Space Center, Houston, TX, and MSE Technology Applications Inc., Butte, MT.

The technology could reduce astronauts' total exposure to space radiation and lessen time spent in weightlessness, perhaps minimizing bone and muscle mass loss and circulatory changes.

Called the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), the technology has been under development at Johnson's Advanced Space Propulsion Laboratory. The laboratory director is Franklin Chang-Diaz, a NASA astronaut who holds a doctorate in applied plasma physics and fusion technology from the Massachusetts Institute of Technology, Cambridge.

Chang-Diaz, who began working on the plasma rocket in 1979, said, "A precursor to fusion rockets, the VASIMR provides a power- rich, fast-propulsion architecture."

Plasma, sometimes called the fourth state of matter, is an ionized (or electrically charged) gas made up of atoms stripped of some of their electrons. Stars are made of plasma. It is gas heated to extreme temperatures, millions of degrees. No known material could withstand these temperatures. Fortunately, plasma is a good electrical conductor. This property allows it to be held, guided and accelerated by properly designed magnetic fields.

The VASIMR engine consists of three linked magnetic cells. The forward cell handles the main injection of propellant gas and its ionization. The central cell acts as an amplifier to further heat the plasma. The aft cell is a magnetic nozzle, which converts the energy of the fluid into directed flow.

Neutral gas, typically hydrogen, is injected at the forward cell and ionized. The resulting plasma is electromagnetically energized in the central cell by ion cyclotron resonance heating. In this process radio waves give their energy to the plasma, heating it in a manner similar to the way a microwave oven works.

After heating, the plasma is magnetically exhausted at the aft cell to provide modulated thrust. The aft cell is a magnetic nozzle, which converts the energy of the plasma into velocity of the jet exhaust, while protecting any nearby structure and ensuring efficient plasma detachment from the magnetic field.

A key to the technology is the capability to vary, or modulate, the plasma exhaust to maintain optimal propulsive efficiency. This feature is like an automobile's transmission which best uses the power of the engine, either for speed when driving on a level highway, or for torque over hilly terrain.

On a mission to Mars, such a rocket would continuously accelerate through the first half of its voyage, then reverse its attitude and slow down during the second half. The flight could take slightly over three months. A conventional chemical mission would take seven to eight months and involve long periods of unpowered drift en route.

There are also potential applications for the technology in the commercial sector. A variable-exhaust plasma rocket would provide an important operational flexibility in the positioning of satellites in Earth orbit.

Several new technologies are being developed for the concept, Chang-Diaz said. They include magnets that are super-conducting at space temperatures, compact power generation equipment, and compact and robust radio-frequency systems for plasma generation and heating.

Coordinated by Johnson's Office of Technology Transfer and Commercialization, the Space Act Agreement calls for a joint collaborative effort to develop advanced propulsion technologies, with no money exchanged between the two parties. Such agreements are part of NASA's continuing effort to transfer benefits of public research and development to the private sector.

ahaning writes: "Yes, even NASA has succumbed to the "e + (someword)" phenomenon. The E-Nose is apparently one of the toys they took along with them on the last shuttle mission. NASA engineers are currently working on making the tool smaller and enabling it to "sniff" out more chemicals. One of the more interesting uses that they give for us on earth is determining whether a plant is ripe enough for harvest. Perhaps someday we could have huge robots out in the middle of a field with nanobugs roaming the place, checking the fruits and vegetables. When they find a ripe one, they signal the robot with their position and it reaches out and plucks the thing carefully off of the plant. That would be cool." Anti-counterfiting, explosive detection, apply-deodorant alert ... the possibilities are endless. What would you use an electronic nose for?

The appropriately-named Nova Express informs us, "According to the Space Weather Page, 'A powerful X-class solar flare erupted...today at 1530 UT. The flare could trigger radio blackouts and high radiation levels in low-earth orbit...the leading edge of the disturbance will trigger geomagnetic storms when it passes by Earth in 30 - 45 hours.'" Coincidentally, Tei'ehm Teuw passed along this article showing what it'll collide with when it gets here: our plasmasphere, the shell of ions and electrons lying at the top of our atmosphere and extending far out into space. This press release has some amazing photos and movies taken by an equally amazing satellite.

Tei'ehm Teuw writes: "In an article from NASA@Today.gov, astronomers are concluding that monstrous black holes weren't simply born big but instead grew on a measured diet of gas and stars controlled by their host galaxies in the early formative years of the universe. These results, gleaned from a NASA Hubble Space Telescope census of more than 30 galaxies, are painting a broad picture of a galaxy's evolution and its long and intimate relationship with its central giant black hole. Though much more analysis remains, an initial look at Hubble evidence favors the idea that titanic black holes co-evolved with the galaxy by trapping a surprisingly exact percentage of the mass of the central hub of stars and gas in a galaxy." This seems an affront to my simplistic understanding of black hole behavior, but heck, we're not even sure black holes exist, anyhow.

One of these examples comes up at least once a month, and I'm going to keep submitting these stories until the situation improves. Maybe that means forever. Today's wakeup call goes to Microsoft corporation, read the account from Tim Burlowski. "

As Bruce says, this looks like a relatively easy one to fix. It could be explained by the complexities of mergers and acquisitions, general confusion, alignment of planets etc, but eternal vigilance is the price of liberty, including as applied to software. Unless Microsoft would like to declare all EULAs null and void ...

Brian De Palma can direct fun movies, even good movies, but never go into one of his movies expecting too much. Written by the brothers who gave us Predator and Wild Wild West, his awful latest Mission to Mars opened this weekend. YRO authors Michael and Jamie were so appalled by this piece of work that they insisted on panning it together, and Jon Katz added his own, slightly hopeful voice to the flaying. Read more for serious spoilers ...

Review 1: Jamie and Michael

Michael: I don't want to keep you in suspense here: movies just don't get much worse than this. And I've seen both Waterworld and Attack of the Killer Tomatoes , so I think I know what I'm talking about. When Brian De Palma says on the movie's official site, "I tried to avoid all the cliches of science fiction movies and to give a whole new look and approach to this fantastic story," all I can think of is that someone needs to call the FBI because the movie he made was obviously switched with someone else's fifth or sixth-rate NYU-film-school production before it reached the theaters.

Jamie: People are going to say we're taking this too seriously, and maybe I did expect too much going in. But I really hate seeing wasted potential.

Michael: The whole premise of the film is based upon a scene where one astronaut makes a zero-gee sculpture of M&M (tm) brand chocolate candies rotating freely and circularly in the shape of a DNA helix. Newton's first law? Anyone? Anyone? Brian De Palma was a physics major? I can see why he switched careers.

Jamie: Thanks for pointing out that URL, Michael. When I read this, I don't feel so bad for slamming the film:

"The various things that happen to the Mars One and Two crews in this film all come out of the physics of what could happen in the situations presented in the story. So, it is realistic and extremely authentic."

Ha. The scriptwriters must have had a quota of a scientific impossibility every ten minutes, and they made their quota easily. Spacesuit thrust jets at shoulder-level. A plot device that depends on the concept of inertia, followed by an attempted rescue that defies the law of inertia.

This was kind of like watching The Poseidon Adventure, and then suddenly halfway through the movie everyone discovers that they can breathe water and eat plankton. No explanation, that's just the way it is. They all swim out of the ship into the Pacific and then climb ashore, wading up onto the Chicago beach.

Michael: We are of course treated to many close-up shots of M&M (tm) brand chocolate candies along the way, including several gratuitous close-up and pan shots where we focus in on the "m"'s and the bag to make sure that we do, indeed, realize that these are M&M (tm) brand chocolate candies and not some inferior brand X chocolate candies, but real, honest-to-god, M&M (tm) brand chocolate candies. If you didn't realize they were M&M (tm) brand chocolate candies, we'll later spill them all over the floor and stare at them for about 20 seconds straight, with a statistically unlikely distribution where the vast majority of the candies land with the "m" up, just to make sure that we notice that these are M&M (tm) brand chocolate candies.

Also plugged: Isuzu, Pennzoil, SGI, Barq's Root Beer, Dr. Pepper, several others that I don't recall just now. The product placement was offensive enough that if I was writing this review I'd make a really big deal of it. Oh, I guess I am. Like watching two hours of commercials.

The "plot," if one must call it that, was as exciting as watching paint dry. Or maybe watching a "cinematic blend of texture and movement" as your clothes whirl around in the dryer. There's a lot of stilted acting, some manufactured crises, and a mysterious alien thing. "Hey look! I can spin the camera around so it looks like I'm in a rotating ring! Let's just spin! For about 3 minutes! We're spinning! Whoo-hoo! Just like a dryer!"

Jamie: Yes; there's homage to 2001 , and then there's a dull recycling of a special effect that was cool 30 years ago.

Michael: Finally we meet an alien. It's glowing, it's got baby blue eyes, it smiles at us, some beatific music swells, and then it hands us some M&M (tm) brand chocolate candies to munch on while it explains, with a handy diorama, just why it has been living in a big human face on Mars for the last few hundred million years.

Jamie: Don't forget the tear. The big sad crystal tear dangling sadly from the sad, sad alien eye. Did I mention it was sad? It was crying, it was so sad. You could tell it was sad because it was crying a big crystal tear. Also the fact that we'd just watched its entire planet destroyed in a fiery cataclysm. So there were two ways you could tell the alien was sad: the tear, and the incineration of its homeworld.

I had thought at first that the alien was a hologram, but later, it takes the humans' hands and it looks awfully real. Except for the fact that it looks awfully fake and computer-generated. Or maybe this alien race just happens to look like big nine-foot fake computer-generated holograms.

Inside, by the way, the Cydonia "face on Mars." This is the structure photographed in 1976 by the Viking probe, which caused wild speculation that it was an artificial construct. Unfortunately for De Palma, it was almost two years ago that high-resolution photos from the Mars Global Surveyor showed it was just another rocky plateau.

Let me spoil the big secret: the aliens are us. We're them. Obviously the scriptwriters graduated from a Kansas high school, because it turns out that the Precambrian explosion was actually seeded by DNA from Mars, thereby producing fish, alligators, brontosauruses, woolly mammoths, and (six hundred million years later) humans. But meanwhile, apparently, the Martians are us. We're them.

So there's a big weird mystery that the astronauts have to solve, which they do by looking at a rotating computerized graphic of a DNA molecule on a spacecraft that can't take off because all its computers are fried.

Michael: The electromagnetic pulse was selective, you see. Important things like wave analyzers and radar guns and remote-controlled toy cars were EMP-protected, while unimportant things like navigation computers were not.

Jamie: Right. Anyway, in the future, all astronauts are required to memorize the entire human genome, because they can look at the graphic which shows human DNA at the atomic level, recognize that two chromosomes [sic] are missing, and (I'm not making this up) enter the missing atomic structure of the chromosomes that were left out. They complete the graphic picture and open up the door to the giant white room which ripped off both 2001 and THX-1138 .

How did the Martians know what the proper DNA sequencing for those two chromosomes were? How did they know how many chromosomes humans have?

Because they're us, we're them. They created multicellular life, and apparently evolution is not random natural selection at all because this weird holographic Martian DNA doesn't change in 600 million years.

I can't stand movies that go back and forth between hard science and the worst kind of pseudoscience. Give me one or the other, OK? But don't base the plot around science and then expect me to suspend scientific disbelief every ten minutes.

One more example. There's a tense moment inside the THX-1138-style white room where Gary Sinese takes off his spacesuit. But he knows it's OK because he watched the air pressure rise: 6psi, 7psi, etc., and as he cracks his gloves off, another character is saying excitedly "12psi, 13psi." So they know that 14psi is Earth normal and we're expected to keep in mind the difference between Mars air pressure and Earth air pressure.

But for the last hour, the plot has hinged on this guy stranded on Mars for a year, who has stayed alive and healthy by growing plants in a canvas greenhouse.

OK, forget the fact that there's no water in the Martian atmosphere - none. Forget the sunlight being half Earth's and filtered through canvas. Forget canvas not producing a greenhouse effect by any stretch of the imagination. Forget all that; he has some magic beans that let him grow a splashy leafy warm wet jungle inside a canvas greenhouse. OK.

This canvas greenhouse is tethered to the Martian dirt by ropes. It flaps in the Martian wind. It looks about as airtight as, well, a Boy Scout tent. And everyone inside it gets to take their helmets off because it is an Earth-pressure atmosphere. Inside the canvas tent. Mars-pressure outside. Earth-pressure inside. Pressure differential between the two: one ton per square foot. Canvas and rope are going to (a) hold down a thousand tons of force and (b) flap in the breeze. Right!

Michael: Don't forget the temperature differential: Mars' average temperature is something like -70 Fahrenheit. Much colder at night, of course. But I guess the magic greenhouse can fend off -70 degree temperatures too. I wish my military-issue shelter half had been made of that material!

Jamie: And finally, at the end of the film, the astronauts climb into the return vehicle and blast off for Earth. As the credits roll they begin starving to death, because it's a six-month minimum journey and it's already been established they have no food. What a happy ending.

Robert Zubrin, co-author of The Case for Mars , was an advisor to this film and he must have held his nose all the way through it. Zubrin is a rocket scientist who has spent the last ten years telling anyone who would listen about a very realistic, practical system for getting people to Mars within ten years. I know he must have had his reasons for signing on but he must be a little embarrassed now that he's seen the finished product.

The reason this movie offends me so much is because it treats the red planet, and space travel in general, with disrespect. It tries to be realistic, but whenever the science gets in the way of Hollywood, Hollywood wins. It did have some powerful moments, true, and they were especially moving if you believe (as I do) that space exploration is important. But when a science-fiction film jettisons the science, it turns into campy space opera - which makes the good parts just that much harder to take.

Michael: This movie looks like it was stitched together from a couple of thoughts the director had and thought were cool. (The studio probably thought they were being slick, capitalizing on Mars enthusiasm generated by NASA missions, so they rushed it through production, never figuring NASA would just hurl probes at the planet like a bunch of lawn darts.) There's zero consistency between those parts, not even hand-waving, you just jump from one to the next with no explanation whatsoever.

Maybe you could justify spending $2 on a non-new-release movie rental of Mission to Mars, assuming it's even released on video, which I honestly think would be a sick joke. But $30, which is what it costs for two people to attend a movie and buy a soda in Manhattan? I'd rather gouge my eyes out. This one definitely gets two thumbs down, and if I had more thumbs, they'd be down too, unless they were holding a bag of M&M (tm) brand chocolate candies.

Review 2: JonKatz

I had two primary responses to Mission. The first was disbelief that Brian De Palma -- the same man who made Wiseguy, and Scarface, among others -- could have made it. The second was awe at the impact of sophisticated animation on movies. It's now possible for a movie to be beautiful, even awe-inspiring and touching at times, and still be a lousy movie. To me, that was the real fate of Mission To Mars.

The characters were so noble, self-sacrificing and one-dimensional, they were practically cartoons. And what Kubrick and Lucas have done so brilliantly -- remember that space and sci-fi ultimately revolve around very human people and stories -- DePalma forgot. He was so busy evoking awe that any sense of humanity was drowned out.

In fact, DePalma's efforts made me appreciate Lucas especially, who I was beginning to resent for all of his mega-hyping. Whatever Lucas's failings, in all of his movies, you're occasionally blown away by the idea of what might be out there, while still identifying with the hapless humans who are trying to sort it out. DePalma gives us instead some God-like alien life force powerful enough to run the universe, but too dumb to figure out the motives of the encroaching humans. And not a single line of dialogue uttered by any star in this movie made them appear real or relevant. Still, the movie was gorgeous, which is why it will sharply disappoint some people. Three or four space scenes, and some of the scenes on Mars, were really jaw-dropping, and made the movie quite worth seeing.

But DePalma seemed way over his head with the subject matter. High-class science fiction isn't all that easily to replicate, it turns out. In terms of character and narrative, Mission to Mars was a stinker. But I won't be surprised if people with imagination and heart will go see it and be touched.

Carey Frey writes " CNN reported today that 'NASA scientists have uncovered evidence of wide, ancient channels that could have formed from the flow of enormous volumes of water.' The movie Mission to Mars opens tonight. I suppose this is all just a coincidence?"

Yeah, right. The production crew spent literally weeks planning the trip, getting to Mars and digging all those channels. "Coincidence," indeed!

Bearpaw writes, "Trying to squeeze the last possible bit of use out of Galileo, NASA may team it up with the Saturn-bound Cassini for a joint mission. " The two will be perform some joint observations of the Jupiter system, as well as doing separate missions on the Jupiter system, including Ganymede as well. Hats off to the folks behind Galileo, whose official mission ended in 1997, but has kept on going.

Keith Gabryelski writes, "space.com has an article on how, in late December 1999, engineers at JPL used a laser beam to move extremely lightweight material using only the pressure of light." For those of you who haven't been keeping up with your science fiction, the idea is that with a tremendously large and incredibly thin sail, you could launch a spacecraft that would be propelled away from the solar system by the miniscule impact force from the light of the sun/gigantic lasers/mirror-focused light striking the sail. The theory is simple enough, but the execution is, shall we say, non-trivial.

rhet writes, "NASA may deliberately crash the $1.5 billion Galileo spacecraft which is exploring Jupiter to avoid contaminating the moon Europa. Scientists believe simple life forms may exist on Europa. There is evidence that Europa has an ocean beneath its ice crust. Read more about it here."

Alexey Goldin writes "An inflatable heatshield --- a new technology with a potential to make space access cheaper will be tested on Feb. 9 by Lavochkin Association (Russia) and DaimlerChrysler Aerospace (Germany). A new word in inflatable toys business :-). " This ranks up there with the Mars Pathfinder, where they just surrounded the lander in airbags and let it drop - elegant engineering at its finest.

Anonymous Coward writes "This official JPL press release describes the current attempt to listen for faint signals from the Mars Lander. They get three windows a day, and it takes 18 hours to process data because the signal is so weak (if it's really there). Too bad they don't have a deal with distributed.net." Interesting thought. Is anyone at distributed.net or JPL interested in pursuing it?

v@mp writes "I noticed a few posts today about space, which reminded me that there will be a total lunar eclipse in North America and Western Europe on Jan. 20. The moon will turn a deep red color for little over an hour around 8 p.m. on the west coast and 11 p.m. on the east coast. I'll see you all "under a blood red sky"--U2. "

toast0 writes "NASA has stopped all attempts to communicate with the mars polar lander. Their press release is very brief, but notes that they will still attempt to find it with the Global Surveyor throughout February. " It's kinda sad really - but NASA's had lot of successes as well lately, which has been good to watch.

Today's TBTF has interesting data and links on the state of X-ray astronomy; ABCNews has an overview. For five months, the orbiting Chandra observatory has been producing great data and potential desktop art. Now, by focusing on a small area of sky, Chanda has resolved what was formerly just known as "X-rayglow" into distinct sources (photo), many of which even Hubble can't find in visible light. The American Astronomical Society will talk about this and other Chandra findings in a live webcast today at 2P.M. EST. For a two-year overview of our universe's secret life in invisible radiation, check out All-Sky Monitor Movies. And oh yeah, in visible-light news, microlensing provides strong evidence for stellar-size black holes being numerous.

Surazal writes "Here's a fine example of Dilbert-esque management decisions that have no basis in reality. The popular Space Science News website will be taken down Monday, simply because management decided the site was not the direction they wanted to go, despite the fact the site was the place for journalists, scientists, and the general population to check up on what's going on up above. This is not a horribly bright PR move in my opinion."

An anonymous reader wrote it to say " This is not your average `we went out there, we repaired it, oh, we are so good' article, but just a happy note after the continous `HST remains in ZGSP... No activity' messages on sci.astro.hubble: finally, after SM3A, new data has been collected. Peharps a little tidbit regarding a new 486 running up there is more interesting for this community... and if you are interesting in those pretty pictures that make good desktop backgrounds, there's always the Space Telescope Science Institute.

adenied wrote to let us know that on Dec 16, NASA successfully launched the Terra Earth Observing System (EOS). This particular satellite is the going to be the flagship of the new EOS system. With this, and other satellites doing similar work, NASA will continue to study the Earth, which has been some of their best work recently.Update: 12/20 08:18 by H :Thanks to Dennis Gerasimov of NASA for clearing up some of the details - click below to learn more.

I would like to point out a mistake in article http://slashdot.org/articles/99/12/18/2340212.shtml about Terra satellite. Terra is not a flagship of EOS program. Terra is the first mission that will be fully integrated into EOS program. The flagship satellite TRMM (Tropical Rainfall Measuring Mission) was launched by NASA together with NASDA (Japan) on November 27, 1997. The satellite is still operational and collects data. More info can be found at http://trmm.gsfc.nasa.gov and the resulting data is located at TSDIS project (the ground data processing system for TRMM) at http://tsdis.gsfc.nasa.gov.
