The Space Rush
Posted by lib1187 in Nerd Stuff, Technology on December 18, 2013
They say space is the final frontier, and like all terran frontiers, people are rushing to claim it.
In a way, we’re in the midst of a space-exploration renaissance, with a bizarre mix of nations, corporations, and random billionaires looking to stake their claim in the heavens.
Earlier this week, China announced that it had landed a robotic rover named Jade Rabbit on the Moon, while Iran is sending monkeys into space. Its the 1960s all over again.
Meanwhile, a host of private entities are making their way into space, helmed by a list of names that looks like it was generated by a random search of Wired.com.
There’s Elon Musk’s SpaceX, which is already delivering cargo to the International Space Station, and hopes to modify its Dragon capsule to carry human passengers.
Then there’s Jeff Bezos’ mysterious Blue Origin, which is testing rockets and capsules at a top secret facility in Texas. Is Bezos trying to explore the galaxy, or conquer it?
Other, less practical schemes include Richard Branson’s Virgin Galactic, which hopes to send a few (very wealthy) tourists to the edge of space soon, and Mars One, which plans to send colonists on a one-way trip to the red planet. Don’t laugh: there are already 200,000 volunteers.
While it may seem haphazard and–at times–zany, this should be encouraging for those who believe space exploration is an important pursuit.
That’s because while we’re a long way from Starfleet and the United Federation of Planets, space exploration is taking on the exact same tone as nearly everything else humans do on a large scale.
Exploration purely for its own sake is a nice sentiment, but what really drives people is money and competition. Whether its the Cold War or potential business opportunities, things tend to get done faster when there’s another motive.
Today’s space pioneers may turn out to be more like the money-grubbing Ferengi or expansionist Romulans than Starfleet officers, but hopefully they will at least ensure that humans leave Earth orbit at all.
Stellar border patrol
Posted by lib1187 in Technology on September 4, 2013
Those who want to build a border fence to keep out illegal immigrants will be happy to know that America already has a space fence.
It’s not for keeping out Klingons, though. Officially known as the Air Force Space Surveillance System, it’s used for keeping track of objects in or near Earth’s orbit.
Three transmitting stations in Alabama, Arizona, and Texas emit radio waves into space, which bounce off objects and are received by six stations in Arkansas, California, Georgia (two stations), Mississippi, and New Mexico.
The Space Fence network extends east to west across the 33rd parallel, detecting any object that passes over. The receiving stations are reportedly sensitive enough to track an object the size of a basketball orbiting 17,200 miles above the Earth’s surface.
Those objects include satellites and space junk. More than 10,500 individual objects are tracked.
Having massive radio arrays spread out across the United States, and calling that series a contraptions a Space Fence, seems ripe for conspiracy theory. While the Fence doesn’t track border-jumping aliens, it does do important work.
Objects in space move very fast (about 17,000 mph in Earth orbit), which makes them dangerous. The Fence can warn the International Space Station if a piece of debris gets too close, or help track a deda satellite as it falls out of orbit, plotting where it will crash.
There’s also an intelligence component to the mission: the Space Fence can detect when a spy satellite passes over the U.S., and it can calculate an object’s country of origin from its launch trajectory. Just think of what the NSA could do with it.
The Space Fence was originally run by the Navy, but it’s now administered by the Air Force’s 20th Space Control Squadron (yes, there really is such a thing). The squadron is at Eglin Air Force Base in Florida, while the data from the Fence is analyzed at the Alternate Space Control Center in Dahlgren, Virginia.
So in a time when it seems like the government can’t do anything right, the Air Force’s space traffic controllers are monitoring thousands of objects zipping around thousands of miles above our heads.
At least for now they are. The Air Force is planning to shut down the Space Fence,which will reportedly save $14 million a year. The Air Force hopes to replace it with a more accurate system.
Hopefully the INS will be able to keep border-hopping aliens out of the country in the meantime.
Other People’s Starships: USS Rhode Island (NCC-72701)
Posted by lib1187 in Nerd Stuff on August 17, 2012
If you buy the Star Trek Hero Clix starter set, you’ll get a ship from the Voyager era called the USS Rhode Island. It may indicate that Starfleet was running out of good names in the 2400s, or it could have been someone’s idea of a joke. Either way, the ship named after America’s smallest state had an important role to play in the Star Trek universe.
Service History
The Rhode Island was commissioned in the early 2400s and sent on a four-year mission of exploration. She was commanded by Captain Harry Kim of Voyager fame.
The ship’s moment of glory actually happened in the alternate future depicted in the Voyager series finale “Endgame.” The Rhode Island comes to the rescue of Admiral Janeway, after her shuttle was attacked by Klingons from whom she had stolen a chrono deflector.
Kim and the Rhode Island chased the two Klingon ships away, then Kim attempted to arrest Janeway. However, she eventually convinces Kim to let her go back in time to help their past selves return to Alpha Quadrant.
Design
The USS Rhode Island is a modified Nova-class science and reconnaissance vessel. These ships were smaller than Starfleet mainstays like the Constitution, Excelsior, and Galaxy-class ships. The Rhode Island and her sisters have a maximum speed of warp 8, and a crew of 80.
The Nova-class ships may have been designed for science, but they still had enough weaponry to defend themselves. Each ship had 11 phaser arrays and three photon torpedo launches (two forward, one aft).
Aesthetically, the Nova-class reflects the tougher look of Starfleet ships designed after the Battle of Wolf 359, when the Federation began seriously expanding its military capabilities to deal with the Borg. The Novas look like mini Sovereign-class ships.
The Rhode Island got some visual modifications to distinguish her from her sister ships. Designer Robert Bonchune made a different bridge and filled in the gap in front of the deflector dish from the USS Equinox filming model, along with some other slight alterations.
It is assumed that these modifications reflect a mid-life refit of the ship meant to extend its service life. The Rhode Island’s brief appearance onscreen obviously doesn’t warrant an in-depth description.
What’s with the name? It turns out that it actually was a bit of a joke. The name was apparently chosen to make fun of Harry Kim, who had finally gotten to command a starship, but got stuck with one named after America’s smallest state.
Kim should consider himself lucky, though. If Starfleet had used the state’s full name, he would have been commanding the USS State of Rhode Island and Providence Plantations.
The name USS Rhode Island might not strike fear into the hearts of Klingons and Romulans, but it’s a nice tribute to the people of Rhode Island. They deserve some recognition for living there.
Other People’s Starships: USS Excelsior (NX/NCC-2000)
Posted by lib1187 in Nerd Stuff on August 1, 2012
The Enterprise gets most of the glory, but there are plenty of other ships in Starfleet. One of my favorites is the Excelsior, a ship that was meant to be the first evolution beyond the Constitution-class ships of the original Star Trek series.
Service History
The USS Excelsior (NCC-2000) was a prototype for a new class of starship. It entered service in the 2280s, toward the end of the Original Series era, in the movie Star Trek III: The Search for Spock. When Kirk brings the badly damaged Enterprise-A back to Earth Spacedock, he moors up next to the Excelsior. Kirk called the new ship Starfleet’s “great experiment.”
What made the Excelsior a “great experiment” was its transwarp drive. According to the Haynes Owners’ Workshop Manual for the USS Enterprise, transwarp drive “relied on an extremely complicated set of equations that boosted the power of a conventional warp engine.” No canonical Star Trek work describes the system in any detail.
The transwarp was supposed to make the Excelsior the fastest ship in Starfleet, but the ship failed on its first trial run and was eventually rebuilt with a conventional warp engine.
After switching back to conventional warp drive, the Excelsior proved to be a capable starship design, spawning an entire class of identical vessels, including the USS Enterprise (NCC-1701-B) seen in Star Trek: Generations.
The Excelsior herself went on to be captained by Hikaru Sulu. After a three-year mission cataloging gaseous planetary anomalies in the Bet Quadrant, Sulu took the Excelsior into Klingon territory to rescue his former shipmates Kirk and McCoy, who had been framed for the assassination of Klingon Chancellor Gorkon. These events played out in Star Trek VI: The Undiscovered Country.
Other Excelsior-class ships made brief appearances in Star Trek: The Next Generation, Deep Space Nine, and Voyager. By the 24th century, these ships were apparently the backbone of Starfleet and were only just being replaced by the larger Galaxy-class.
The Excelsior’s motto was “No matter where you go, there you are.”
Design
The Excelsior had 32 decks, and was capable of saucer separation. Armament included Type 8 phaser emitters and fore and aft photon torpedo launchers.
The script for Search for Spock called for a ship that would make the Constitution-class Enterprise look old fashioned. The Excelsior was described as a “super starship” with lines similar to the Enterprise, “but she is clearly bigger, sleeker, and very new. She sits at her mooring like the new Queen of Space.”
Industrial Light & Magic designer William George based the Excelsior’s look on what he thought the Enterprise would look like if it had been designed by the Japanese.
The result is one of the best looking ships in Starfleet. The Excelsior’s low profile and elongated lines make it look like it’s at warp even when it’s standing still.
I always liked that design; it’s much less bulky than other Star Trek ships. I also think the name is kind of funny. I picture the crew carrying a bust of Al Gore around, the same way the USS Ronald Reagan carries a bust of the Gipper. I also like to imagine the captain yelling “Excelsior!” as the ship warps off into the unknown.
Space: Whose final frontier?
Posted by lib1187 in Nerd Stuff, Technology on May 25, 2012
Space may be the final frontier, but it’s already commercial. SpaceX’s privately launched capsule began its journey to the International Space Station on Tuesday, becoming the first of its kind. Space exploration started out as the mother of all public-private partnerships but, at least in the United States, the private sector seems to be leaving the government behind.
Seeing someone take an interest in space exploration is encouraging, but it’s just not the same without NASA taking the lead. Some might say that it doesn’t matter: if the private sector can do something better than the government, why waste taxpayers’ money? The ends should be the most important goal, so as long as someone is going into space, it should not matter whether they are a government agency or a private corporation.
SpaceX seems like a major change in the way we explore space, but private companies have been involved from the beginning. Who do you think built the rockets? NASA may have run all previous space missions but, like any other government project, the hardware was produced by the private sector. The Redstone booster that launched America’s first astronauts was built by Chrysler; the Mercury capsule was built by McDonnell.
So why not cut out the middleman? Couldn’t private interests use their own resources more effectively? Not really. SpaceX will continue doing what it does as long as Elon Musk and his small cadre of investors have money to pour into it, and are still interested in going into space.
That is why government involvement in space is so important. Where private companies only have their investors’ interests in mind, governments have an entire nation’s. SpaceX has shown what a small company full of dedicated techies can do, but imagine what several corporations, striving toward one goal, could do. At one time, such a collaboration was able to get men to the Moon.
There is also the matter of money. In the end, private corporations need to turn a profit in order to exist, and sometimes that takes precedent over everything else. The future depicted in Star Trek is very appealing, but what corporation would want to fund Starfleet? Will space travel be more like the universe of Alien, where the Weyland-Yutani Corporation only operates spaceships for the sake of harvesting otherworldly resources?
Launching privately-operated spacecraft is better than not launching any, but mankind should not settle. The United States should go into space on its on terms, not the terms of a handful of wealthy investors. Government leadership and private resources has worked so far, there is no reason why private interests need to go it alone now. A lack of conviction is no reason to trade the Enterprise for the Nostromo.
How to name a spaceship
Posted by lib1187 in Nerd Stuff on May 18, 2012
So you’ve got a spaceship. You’re ready to go boldly where no one has gone before, or to let the computers figure it out while you hypersleep and wait for the facehuggers. Either way, your ship will need a name.
Naming ships has been an important tradition in in the maritime world since the first seafarers, and that tradition most likely continue with spacefaring vessels. Here are some spaceship naming tips.
Military
Naval vessels are named after almost everything, so we’ll start here. Several sci-fi series, like Star Trek, believe the military naming tradition will carry over to future space fleets, which is why Starfleet ships carry the prefix “USS” and a hull number. Military names add some gravitas, and could possibly reference seagoing vessels from centuries past.
Naval ships are assigned specific types of names depending on their class. Obviously, these don’t all apply to spacecraft, but they give a good indication of how a name matches up with a ship’s purpose:
Aircraft Carriers: presidents, battles, famous navy ships
Battleships: states
Cruisers: cities
Destroyers and escort ships: Navy and Marine personnel
Submarines: fish and marine life (more recently, states and cities)
Amphibious Assault Ships: same as aircraft carriers
Destroyer/Submarine Tenders: national parks
Patrol Craft: numbers only
Transports: various
Geography
Choosing a name based on an Earth landmark will be a good way to remind you of home as you cross the galaxy. They are also a good may to circumvent national boundaries; mountains and rivers are more politically neutral than historical figures or events from a country that may be part of a unified world government in the future.
Adjectives
These are always a good bet, since, by definition, they describe how awesome your ship is. Adjectives are a favorite of the Royal Navy; examples include HMS Invincible, HMS Indomitable, and HMS Illustrious. One of my personal favorites is Intrepid, first used on a U.S. Navy ketch during the Barbary Wars, then on a World War II aircraft carrier, and eventually on a class of Star Trek ships. You don’t have to choose a name that begins with “I,” but there are plenty of good ones out there.
People
Naming a ship after an important person says a lot about the ship’s creators. A ship can embody the qualities of its namesake, or honor their remarkable achievements. That’s why so many American ships are named after presidents, especially ones that led the country through wars. On the other hand, Sea Shepherd (of Whale Wars fame) named their ships Steve Irwin and Bob Barker. Conceivably, a future nerd society could have ships named George Lucas and Isaac Asimov.
References
A ship name is the perfect place to slip some allusion into a sci-fi story. In the Alien series, several ships, including the Nostromo and Sulaco, have names that refer to Joseph Conrad. Appealing to nerds isn’t the only option; references to mythology are also a good way to give your ship a cool, original, name with some meaning. These names aren’t as obvious as Mount Everest or George Washington, which makes them a little more realistic and a little more interesting. In a spacefaring civilization, all the “good” names will get taken; shipwrights will have to get creative, and so will you.
For the sake of concision, these are just five of the many possible types of names. These five are the most popular types of ship names, but the possibilities are almost infinite. You can even combine two cool-sounding words like Millennium Falcon. Just try to think as an actual ship captain or owner: would you really want a certain name if the ship was real?
Remember that, no matter what a ship’s name is, tradition dictates that it is female. Even if your ship’s name is the Sean Connery, you should refer to it as a “she.” They may just be machines, but ships have always had a romantic quality. That’s why naming them is so important.
