NASA's New Mega-Rocket, Orion Capsule on Track for Future Test Flights

As reported by Space.com: A new era of space exploration — supported by a history-making new mega-rocket and a spacecraft designed to deliver humans into deep space — could be on the horizon for NASA.  

The space agency is gearing up to build the largest and most powerful rocket in history. The huge launcher, called the Space Launch System (SLS), will move a new spacecraft dubbed Orion, designed to send up to four astronauts farther into the solar system than ever before. A short list of destinations includes the moon, nearby asteroids and, eventually, Mars.

Everyone is looking forward to 2021, the year when the first manned launch will occur. But before that happens, the rocket and spacecraft will have to pass a number of tests. [NASA's Space Launch System Rocket in Pictures]

SpaceX Unveils Manned Dragon ‘Space Taxi’

As reported by Universe Today: SpaceX CEO, founder and chief designer Elon Musk is set to unveil the manned version of his firms commercial Dragon spaceship later this week, setting in motion an effort that he hopes will soon restore America’s capability to launch US astronauts to low Earth orbit and the International Space Station (ISS) by 2017.

Musk will personally introduce SpaceX’s ‘Space Taxi’ dubbed ‘Dragon V2’ at what amounts to sort of a world premiere event on May 29 at the company’s headquarters in Hawthorne, CA, according to an official announcement this evening (May 27) from SpaceX.

“SpaceX’s new Dragon V2 spacecraft is a next generation spacecraft designed to carry astronauts into space,” according to the SpaceX statement.

The manned Dragon will launch atop the powerful SpaceX Falcon 9 v1.1 rocket from a SpaceX pad on the Florida Space Coast.

Dragon was initially developed as a commercial unmanned resupply freighter to deliver 20,000 kg (44,000 pounds) of supplies and science experiments to the ISS under a $1.6 Billion Commercial Resupply Services (CRS) contract with NASA during a dozen Dragon cargo spacecraft flights through 2016.

Musk is making good on a recent comment he posted to twitter on April 29, with respect to the continuing fallout from the deadly crisis in Ukraine which has resulted in some US economic sanctions imposed against Russia, that now potentially threaten US access to the ISS in a boomerang action from the Russian government:

“Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on with @NASA. No trampoline needed,” Musk tweeted.

“Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup,” Musk added.

The ‘Dragon V2’ is an upgraded, man rated version of the unmanned spaceship that can carry a mix of cargo and up to a seven crewmembers to the ISS.

Dragon is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the ISS by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.

Since that day, US astronauts have been totally dependent on the Russian Soyuz capsules for ferry rides to orbit and back.

The Boeing CST-100 and Sierra Nevada Dream Chaser ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.

All three company’s have been making excellent progress in meeting their NASA mandated milestones in the current contract period known as Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.

However, US progress getting the space taxis actually built and flying has been repeatedly stifled by the US Congress who have severely cut NASA’s budget request for the Commercial Crew Program by about half each year. Thus forcing NASA to delay the first manned orbital test flights by at least 18 months from 2015 to 2017.

The situation with regard to US dependency on Russian rocketry to reach the ISS has always been awkward.

But it finally took on new found importance and urgency from politicos in Washington, DC, since the ongoing crisis in Ukraine this year exposed US vulnerability in a wide range of space endeavors affecting not just astronaut rides to the ISS but also the launch of the most critical US national security surveillance satellites essential to US defense.

US space vulnerability became obvious to everyone when Russia’s deputy prime minister, Dmitry Rogozin. who is in charge of space and defense industries, said that US sanctions could “boomerang” against the US space program and that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”

Rogozin also threatened to cut off exports of the Russian made RD-180 rocket engines which power the first stage of the United Launch Alliance (ULA) Atlas V rocket used to launch numerous US National Security spy satellites.

“Moscow is banning Washington from using Russian-made rocket engines, which the US has used to deliver its military satellites into orbit,” Rogozin said at a media briefing held on May 13.

NASA is also a hefty user of the Atlas V for many of the agency’s science and communication satellites like the Curiosity Mars rover, MAVEN Mars orbiter, MMS, Juno Jupiter orbiter and TDRS.

Musk and SpaceX have also filed lawsuits against the US Air Force to legally block the importation of the RD-180 engines by ULA for the Atlas V as a violation of the US economic sanctions.

So overall, US space policy is in a murky and uncertain situation and Musk clearly aims for SpaceX to be a central and significant player in a wide range of US space activities, both manned and unmanned.

The First Driverless Cars Will Be Electric, Thanks to Google & Tesla, And That’s Important

As reported by GigaOm: Mentioned very briefly, and with far less emphasis than the many descriptions of the tiny size of Google’s new driverless car, is that Google’s new experimental fleet of robotic cars are electric.

That’s important because as one of the leaders of developing the software and artificial intelligence that will move autonomous cars through the streets, Google is now also helping set the path for the hardware of the future industry, and it’s skewing that path toward electric vehicles.  

Google has a long history of tinkering with electric cars. They built up a large fleet of plug-in cars for Google employees to use years ago. The program was called theRechargeIT Initiative and was funded with $10 million. I met one of the leaders of that group at an event over six years ago. Today if you go walk around Google’s campus it’s got one of the largest employee fleets of plug-in hybrid and all-electric cars out there.

We already knew that Google was interested in exploring pairing autonomous cars with electric cars. I had heard that Google and Tesla were collaborating on some kind of tech around EVs and robotic cars awhile  back, and both Google and Tesla have confirmed that they’d had discussions, though there were no concrete plans here. The leaders of both companies have big-picture end games to make transportation more sustainable in general. I asked Tesla if they had contributed any work to Google’s recently announced robotic car fleet, and I’ll update this when I hear back.

Electric car company Tesla has also maintained that it wants to do its own autonomous car technology for its cars perhaps by 2016. The first driverless tech in a Tesla car will likely be a mode that is like a very good cruise control — picture auto pilot in a plane. But Tesla’s entire goal is to make its cars cheaper, so likely it would need to build its own system that is much less expensive than the current Google one.

That the two most important companies building autonomous car tech will implement their products in electric cars is a big step for the future of personal transportation and an early important market for getting the next generation of cars off of using oil for a fuel. Will robot cars help push electric cars out there, or vice a versa? I can envision both.

It also just makes sense from a technology perspective. Internal-combustion cars, which have a lot of moving parts and create a lot of heat waste, are far more complex than electric cars. Electric cars are like large gadgets, that (obviously) run on electricity, making them a more natural fit with an all-computer powered car. Tesla CEO Elon Musk even called the internal combustion engine a ridiculous way to make a car at an event recently.

Google’s Next Phase in Driverless Cars: No Brakes or Steering Wheel

As reported by the New York Times: Humans might be the one problem Google can’t solve.

For the past four years, Google has been working on self-driving cars with a mechanism to return control of the steering wheel to the driver in case of emergency. But Google’s brightest minds now say they can’t make that handoff work anytime soon.

Their answer? Take the driver completely out of the driving.

The company has begun building a fleet of 100 experimental electric-powered vehicles that will dispense with all the standard controls found in modern automobiles. The two-seat vehicle looks a bit like the ultracompact Fiat 500 or the Mercedes-Benz Smart car if you take out the steering wheel, gas pedal, brake and gear shift. The only things the driver controls is a red “e-stop” button for panic stops and a separate start button.

The car would be summoned with a smartphone application. It would pick up a passenger and automatically drive to a destination selected on a smartphone app without any human intervention.

Google won’t say if it intends to get into the car manufacturing business or simply supply technology to carmakers, but it says there are plenty of possibilities if it can persuade regulators to allow cars with no drivers. One potential use: driverless taxi cabs.

In an interview at Google’s headquarters here, Sergey Brin, a Google co-founder who is actively involved in the research program, said the company decided to change the car project more than a year ago after an experiment in which Google employees used autonomous vehicles for their normal commutes to work.
There were no crashes. But Google engineers realized that asking a human passenger — who could be reading or daydreaming or even sleeping — to take over in an emergency won’t work.

“We saw stuff that made us a little nervous,” said Christopher Urmson, a former Carnegie Mellon University roboticist who directs the car project at Google.

The vehicles will have electronic sensors that can see about 600 feet in all directions. Despite that, they will have rearview mirrors because they are required by California’s vehicle code, Dr. Urmson said. The front of the car will be made from a foamlike material in case the computer fails and it hits a pedestrian. It looks like a little bubble car from the future, streamlined to run by itself — a big change from the boxy Lexus SUV Google has been retrofitting the last few years with self-driving technology.

The new Google strategy for autonomous cars is a break from many competing vehicle projects. Mercedes, BMW and Volvo have introduced cars that have the ability to travel without driver intervention in limited circumstances — though none completely eliminate the driver.

That feature, which is generally known as Traffic Jam Assist, allows the car to steer and follow another vehicle in stop-and-go highway driving at low speeds. In the Mercedes version, the system disengages itself if the driver takes his hands off the steering wheel for more than 10 seconds.

Volvo said that by 2017 it planned to have the cars in the hands of ordinary consumers for testing in the streets of Gothenburg, Sweden, where the company has its headquarters.

In the interview, Mr. Brin acknowledged those advances, but said they were incremental. “That stuff seems not entirely in keeping with our mission of being transformative,” he said.

The current plan is to conduct pilot tests in California, starting with ferrying Google employees between buildings around its sprawling corporate campus here.

Laws permit autonomous vehicles in California, Nevada and Florida. But those laws have generally been written with the expectation that a human driver would be able to take control in emergencies.

Google executives said the initial prototypes would comply with current California automated-driving regulations, issued on May 20. They will have manual controls for testing on California public roads.

In the future, Google hopes to persuade regulators that the cars can operate safely without driver, steering wheel, brake or accelerator pedal. Those cars would rely entirely on Google sensors and software to control them.

So where might the driverless cars be used besides at Google’s offices?

Last year, Lawrence D. Burns, former vice president for research and development at General Motors and now a Google consultant, led a study at the Earth Institute at Columbia University on transforming personal mobility.

The researchers found that Manhattan’s 13,000 taxis made 470,000 trips a day. Their average speed was 10 to 11 m.p.h., carrying an average of 1.4 passengers per trip with an average wait time of five minutes.
In comparison, the report said, it is possible for a futuristic robot fleet of 9,000 shared automated vehicles hailed by smartphone to match that capacity with a wait time of less than one minute. Assuming a 15 percent profit, the current cost of taxi service would be about $4 per trip mile, while in contrast, it was estimated, a Manhattan-based driverless vehicle fleet would cost about 50 cents per mile.

The report showed similar savings in two other case studies — in Ann Arbor, Mich., and Babcock Ranch, a planned community in Florida.

Google is one of the few companies that could take on a challenge like that, said John J. Leonard, a Massachusetts Institute of Technology roboticist. But he added: “I do not expect there to be driverless taxis in Manhattan in my lifetime.”

Mr. Brin said the change in Google’s car strategy did not mean that the company was giving up on its ultimate goal of transforming modern transportation.

“Obviously it will take time, a long time, but I think it has a lot of potential,” he said. “Self-driving cars have the potential to drive in trains much closer together and, in theory, in the future at much higher speeds.

“There is nothing to say that once you demonstrate the safety, why can’t you go 100 miles per hour?”

Should the Unlicensed be Allowed to ‘Drive’ Autonomous Cars?

As reported by RoboHub: Earlier this month, when we asked people about your general thoughts on autonomous cars, we found that one of the main advantages of autonomous cars is that those who are not licensed to drive will be able to get to places more conveniently. This led us to wonder more about who should be able to drive an autonomous car.  

We asked three questions through Robohub to find out more. 

Should a child under the legal driving age be allowed to ride driverless cars alone?

Remember the first time your parents handed you their car keys, or took you out for your very first driving lesson? For some of us, that moment came with our parents beaming aloud expressions of uncertainty, anxiety, and worry. Some of this adult/parental psyche may be at play with this question.

About half of the participants (52%) said that children under the legal driving age should not be able to ride driverless cars. This is not entirely surprising. Currently, under driving regulations, children under a certain age (typically late teen years) are not allowed to drive cars because we have reasons to believe that it is not entirely safe to let them drive. By allowing a child to ride autonomous cars alone, people may be concerned about scenarios where the car makes an error or requires the assistance of a human decision-maker during an emergency situation. Interestingly, 38% of the participants believe that children should be able to ride driverless cars alone and the other 10% also think that children should be able to drive autonomous cars with proven technology and specific training. This brings us to a fairly even split in opinion on the issue of children driving autonomous vehicles.

The results may not mean that 48% of the participants would be comfortable putting a newborn baby in an autonomous car to be delivered to his/her grandparents’ house. But it could mean that with a proven technology and some training, the legal driving age could be lowered for ‘driving’ autonomous cars. It makes sense that a shift in driving age would depend on the capability and reliability of the technology. For example, if all cars today had a high probability of breaking down in the middle of the road, then our driver’s license exams may have included a preliminary car mechanics test.

For now, it seems that people are more hesitant to put children in autonomous cars alone. It would be interesting to see if this will change as the technology drives out onto the road and demonstrates its safety and reliability.

Should a senior who no longer has a legal driving license be allowed to ride driverless cars alone?

Compared to the case of the underage drivers, it seems that the majority of the participants (67%) consider it acceptable to have a senior with no legal driver’s license ride an autonomous vehicle alone. Perhaps our participants expect a senior who has had a driver’s license to be able to better handle any emergency or unexpected situations than children, since they have driving experience to rely on if necessary. However, it is possible that some of the seniors are without license due to low cognitive and/or physical capabilities. In such cases, the concerns over the rider being able to handle emergency/unexpected situations is not different from the above unlicensed child rider situation.

This may be one of the reasons why 26% of the participants are not in support of unlicensed seniors riding the autonomous cars alone. However, similar to the responses to the first question, 7% of the participants thought that they would answer yes to this question only if there are limitations placed on where the senior would be allowed to ride the vehicle and whether they would have to pass some type of training to ride the vehicle.

Should a legally blind person be allowed to ride driverless cars alone?

Interestingly, the split of the votes for this question lies somewhere between the above two questions. 58% of the participants answered “yes” while 37% said “no” and the remaining 5% answered with a conditional “yes”. So why is a significant portion of the responses affirmative considering that being able to see is one of the most essential functions we rely on when we drive?

Perhaps people expect the legally blind driver to be able to receive enough information and be able to make informed driving decisions to handle emergency or unexpected situations. It maybe that people are in support of the blind driver scenario because the benefits of driving outweigh the risks for legally blind persons, more so than for a child or a senior. Compared to the case of the underage driver, a legally blind person (assumed adult) is deemed to have better decision making abilities and able to take responsibilities, which are both important requirements for a driver besides being able to perceive the environment.

Drawing a line on who should and should not be able to ride an autonomous vehicle seems to depend on a number of factors, and that doesn’t really include whether the individuals are legally licensed to drive under today’s regulations. Based on the results, the capability and reliability of the autonomous vehicles and the cognitive and physical ability of the rider are likely to change the way we allow different individuals to ‘drive’. One thing is for certain: regulations on who can drive will have to be reconsidered once autonomous vehicles start roaming the streets.

Segway Just Started a Three-Wheeled Vehicle War

As reported by The Verge: Segway's claim to fame is its two-wheeled scooters' balancing act, but today it's introducing a product that stands a bit more firmly on the ground: the three-wheeled SE-3 Patroller. As its name suggests, the Patroller is meant for law enforcement and public safety uses. It doesn't really have any special tricks like the traditional Segway does, but it's being pitched as a natural extension of the scooter's product line nonetheless. Their obvious connections are pretty limited though: they're both battery powered, and they both have wheels.
  
The real reason that Segway is introducing the SE-3 isn't because it's so natural of an extension though. It's likely doing it because its competitor T3 Motion has been taking market share away from traditional Segways with three-wheeled vehicles of its own. In fact, following the SE-3's introduction today, T3 Motion even made an effort to counter Segway with an announcement that it was working on an even more advanced three-wheeled vehicle.  

"We began this development more than a year ago on the heels of our former CEO joining Segway and announcing they were going to move towards a three wheel platform," William Tsumpes, CEO of T3 Motion said in a statement. Shipments of the SE-3 will begin in June, at $11,999, at which point you may just start to see how they stand up to T3 Motion's vehicles.

SpaceX Plans DragonFly Landing Tests

As reported by NBC News: Billionaire Elon Musk's high-flying space venture, SpaceX, has provided fresh details about its plan to test a Dragon capsule that can use retro rockets to make a soft landing on Earth — and perhaps eventually on Mars.  

The prototype test project, code-named DragonFly, would be conducted at SpaceX's test facility near McGregor, Texas, according to a draft environmental assessment released by the Federal Aviation Administration. The document is part of the regulatory requirements for issuing an experimental permit for the tests.

In the 76-page FAA document, the DragonFly RLV is described as a 7-ton Dragon capsule equipped with eight SuperDraco thrusters, an integrated trunk and up to four landing legs. The program calls for a series of increasingly ambitious tests, starting with a parachute-assisted landing and proceeding to a full propulsive landing and rocket-powered hops.

DragonFly is just one of several initiatives being pursued by Musk's California-based venture to turn SpaceX's Falcon 9 rocket and Dragon capsule into a fully reusable space transport system. The Texas facility is already being used for tests of a rocket prototype called the Falcon 9R, which is designed to fly itself back to a landing pad after sending up its payload.

Unmanned versions of the Dragon capsule have made four round trips to the International Space Station, including one resupply mission that wound up last weekend. Last month, Musk announced in a Twitter update that the hardware for the Dragon 2 would be unveiled on May 29. That would pave the way for the DragonRider, a version capable of ferrying astronauts to and from the International Space Station.

The DragonFly prototype's landing technology would eventually be incorporated into a future version of the seven-person DragonRider capsule. It also could be used on interplanetary trips, including a Mars mission code-named "Red Dragon" or Icebreaker. Last weekend, the 42-year-old Musk reported that he was making progress on a plan to send colonists to Mars during his lifetime.
