Space Legs for NASA's Robonaut 2 to Ride SpaceX Dragon Into Orbit

Posted: at 6:45 am

A robotic humanoid astronaut on the International Space Station is about to get its legs.

NASA has crafted a pair of space legs for Robonaut 2, its robotic astronaut torso on the space station now. The legs will fly to space aboard SpaceX's unmanned Dragon capsule, set to launch from Cape Canaveral Air Force Station in Florida on Monday (April 9).

Once installed, the legs will give Robonaut 2 which is currently attached to a support post on the orbiting outpost an extended leg span of 9 feet (2.7 meters), according to NASA. The legs are expected to allow Robonaut 2 (R2 for short) the flexibility to move about the station. Eventually, NASA officials hope that R2 will be able to perform repetitive tasks inside and outside the space laboratory, allowing astronauts to focus on more complex work.

"The new legs are designed for work both inside and outside the station, but upgrades to R2's upper body will be necessary before it can begin work outside the space station," NASA officials said in a statement released in March.

R2's legs are not like a human's lower limbs. The legs each have seven joints and in place of feet, the robot will have an "end effector" attached to the end of each leg, NASA officials said. The end effector allows R2 to use sockets and handrails inside and outside the station, and the two devices also come equipped with vision tools that controllers can use to visualize and automate the movements of the legs, NASA added.

Robonaut 2 has been onboard the space station since February 2011, and since that time, it has performed a variety of tasks to show its usefulness in microgravity. The $2.5 million humanoid robot can flip switches, press buttons and turn nobs.

"In preparation for future spacewalks, R2 has worked inside the space station with space blankets and other flexible materials, both through ground control and through teleoperation by the on-board crew," NASA officials added.

Monday's launch will be the third official cargo mission to the International Space Station for SpaceX. The private spaceflight company has a $1.6 billion contract with NASA to fly 12 missions to the station using the Dragon capsule and Falcon 9 rocket.

NASA is planning to do initial checks of the legs in late June, and after that checkup, Robonaut 2 is expected to make its first steps on the space station.

The space agency also has a twin R2 on the ground. Recently, that robot was used to perform an ultrasound scan on a mannequin and administer an injection to the dummy. The Earth-bound R2 was remotely controlled by a doctor while performing the tasks, a potentially useful option in space, where astronauts are far from hospitals.

NASAs new Martian braking system paving way to easier human colonization

Posted: at 6:45 am

WATCH: Seven Minutes of Terror

TORONTO If humans are going to settle on Mars, it means better technology will be needed to deliver heavier payloads. And NASA already has a plan for that.

NASAs Jet Propulsion Laboratory (JPL) revealed its Supersonic Inflatable Aerodynamic Decelerators (SIAD) on Wednesday, a system that will be able to deliver 15 times the weight of the last payload to Mars, the Mars Science Laboratory, more familiarly known as Curiosity.

Mars has very little atmosphere (therefore less drag to slow things down), which makes landing there somewhat challenging. The exciting landing of Curiosityused several technologies, but it still relied on technology that was 40 years old, mainly a parachute.

But the parachutes that are currently available for landing on the red planet arent capable of being affixed to large payloads. Thats where NASAs UFO-looking braking mechanism comes in.

The atmosphere of Mars is extremely thin. Its about one per cent the thickness of Earths atmosphere, which means that in order to slow down, you need really big things to react against the atmosphere, more surface area, or drag area, and thats why you need bigger parachutes, said Ian Clark, Principal Investigator for the Low-Density Supersonic Decelerator (LDSD) program.

Eventually, humans are going to land on Mars, Clark said. And the task of sending materials ahead of time or even human beings themselves will require improved accuracy and heavier payloads.

When you start talking humans, you start talking masses 10 to 15 tons. MSL was a one-tonne rover, and that was a very difficult landing, in it took all of the technologies we had available, said Clark.

If we want to go bigger, were going to need something new.

Researchers Develop Bacterial FM Radio

Programming living cells offers the prospect of harnessing sophisticated biological machinery for transformative applications in energy, agriculture, water remediation and medicine. Inspired by engineering, researchers in the emerging field of synthetic biology have designed a tool box of small genetic components that act as intracellular switches, logic gates, counters and oscillators.

But scientists have found it difficult to wire the components together to form larger circuits that can function as genetic programs. One of the biggest obstacles? Dealing with a small number of available wires.

A team of biologists and engineers at UC San Diego has taken a large step toward overcoming this obstacle. Their advance, detailed in a paper which appears in this weeks advance online publication of the journal Nature, describes their development of a rapid and tunable post-translational coupling for genetic circuits. This advance builds on their development of biopixel sensor arrays reported in Nature by the same group of scientists two years ago.

The problem the researchers solved arises from the noisy cellular environment that tends to lead to highly variable circuit performance. The components of a cell are intermixed, crowded and constantly bumping into each other. This makes it difficult to reuse parts in different parts of a program, limiting the total number of available parts and wires. These difficulties hindered the creation of genetic programs that can read the cellular environment and react with the execution of a sequence of instructions.

The teams breakthrough involves a form of frequency multiplexing inspired by FM radio.

This circuit lets us encode multiple independent environmental inputs into a single time series, said Arthur Prindle, a bioengineering graduate student at UC San Diego and the first author of the study. Multiple pieces of information are transferred using the same part. It works by using distinct frequencies to transmit different signals on a common channel.

The key that enabled this breakthrough is the use of frequency, rather than amplitude, to convey information. Combining two biological signals using amplitude is difficult because measurements of amplitude involve fluorescence and are usually relative. Its not easy to separate out the contribution of each signal, said Prindle. When we use frequency, these relative measurements are made with respect to time, and can be readily extracted by measuring the time between peaks using any one of several analytical methods.
