Three astronauts from Russia, the United States and Italy have become the newest residents of the International Space Station after a record-setting trip.

Five hours and 40 minutes after asuccessful Soyuz rocket launchfrom the Baikonur Cosmodrome in Kazakhstan, Russian cosmonaut Fyodor Yurchikhin, NASA's Karen Nyberg and Italy's Luca Parmitano docked their Soyuz spacecraft at the orbiting laboratory at 10:10 p.m. ET Tuesday. The new crew will remain on the space station for the next six months.

"I've never felt better in my life," Yurchikhin said just after the Soyuz docked at the station while sailing high above the South Pacific.[See Photos from the Launch and Docking]

Fast track to spaceTuesday's same-day launch and docking was the second express flight to the International Space Station by an astronaut crew.

Unmanned cargo vessels have made this kind of trip several times before, but the one-day missions are a relatively new method of flying for manned Soyuz capsules. Typically, it takes astronauts about two days to reach the space station. The fast-track itinerary calls for the capsule to orbit the Earth only four times, shortening the amount of time the astronauts need to spend in the cramped spaceship.

The first Soyuz crew to fly to the station using this expedited technique were waiting to greet Nyberg, Parmitano and Yurchikhin after the opening of the capsule's hatch. The three newest space station residents will join NASA's Chris Cassidy and Russian cosmonauts Alexander Misurkin and Pavel Vinogradov to round out the Expedition 36 crew.

"[Your trip was] even faster than Pavel," a Russian mission controller joked with Yurchikhin after docking. The Russian Soyuz commander beat Vinogradov's time to the station by six minutes.

International crew takes short cut to space station

Posted: at 6:44 pm

By Irene Klotz

CAPE CANAVERAL, Florida (Reuters) - A Russian spaceship took a shortcut to the International Space Station on Tuesday, delivering a veteran cosmonaut, a rookie Italian astronaut and an American mother on her second flight to the outpost in less than six hours.

The capsule slipped into its berthing port at 10:10 p.m. EDT about 250 miles above the south Pacific Ocean.

"Everything went very well," NASA mission commentator Kelly Humphries said during a televised broadcast of the docking.

Typically, the journey takes two days, but Russian engineers have developed new flight procedures that tweak the steering maneuvers and expedite the trip.

One other crew capsule and several cargo ships previously have taken the fast route to the station.

The express ride to the station began at 4:31 p.m. EDT when a Russian Soyuz rocket soared off its launch pad at the Baikonur Cosmodrome in Kazakhstan and deposited the crew's capsule into orbit. The spaceship circled around the planet less than four times before catching up to the station, a $100 billion project of 15 nations.

Overseeing operations from aboard the capsule was veteran cosmonaut Fyodor Yurchikhin, 54, who will be living aboard the station for the third time. The former commander also flew on NASA's now-retired space shuttle.

He was joined on the Soyuz by first-time astronaut Luca Parmitano, 36, a major in the Italian Air Force. Parmitano, who initially studied political science and international law at the University of Naples, is the first Italian to be assigned to a long-duration mission aboard the station, which is a laboratory for biomedical, materials science and other research.

"This is very momentous," Parmitano said in a preflight NASA interview.

Soyuz capsule docks with space station

Posted: at 6:44 pm

MOSCOW (AP) A Soyuz capsule carrying an American, Russian and Italian successfully docked Wednesday with the International Space Station, where the new crew will spend six months conducting a variety of experiments.

The docking took place at 8:10 a.m. (0210 GMT, 10:10 p.m. EDT) less than six hours after the Russian spacecraft lifted off from the Baikonur Cosmodrome, which Russia leases in Kazakhstan.

Live footage provided by NASA TV showed it soaring into the clear night sky. About four minutes later, the announcer said the Soyuz was traveling at 4,700 miles per hour (about 7,500 kilometers per hour).

The cramped capsule carrying NASA's Karen Nyberg, Russian cosmonaut Fyodor Yurchikhin and Italy's Luca Parmitano orbited the Earth four times before docking with the space station.

After docking, two hours passed before pressure equalized between the capsule and the station, allowing safe entry.

The three new arrivals were greeted by NASA's Chris Cassidy and Russians Alexander Misurkin and the station's commander Pavel Vinogradov, who have been aboard the space station since late March.

"It was a pretty cool ride," Nyberg said upon arrival.

Cassidy had shaved his head clean to match Parmitano's look and got a thumbs-up from the Italian.

Yurchikhin, 54, is a veteran of three previous spaceflights, while the 36-year-old Parmitano, a former test pilot, is making his first trip into space. Nyberg, 43, spent two weeks in space in 2008 as part of a U.S. space shuttle crew.

Shortly after their arrival, the incoming team spoke via video link with their relatives and officials back in Baikonur. Parmitano's mother wept throughout the chat with her son.

Astronauts Launch to Space Station on Express Trip

Posted: at 6:44 pm

A Russian rocket carrying a trio of astronauts is on its way to the International Space Station.

NASA astronaut Karen Nyberg, European Space Agency astronaut Luca Parmitano and Russian cosmonaut Fyodor Yurchikhin successfully launched aboard the Russian Soyuz TMA-09M spacecraft from the Baikonur Cosmodrome in Kazakhstan toward the orbiting outpost today (May 28) at 4:31 p.m. EDT (2031 GMT). The local time was early Wednesday.

"Soyuz blazing into the night sky over Kazakhstan," NASA spokesman Kelly Humphries said upon launch.

Yurchikhin, the commander of the Soyuz, chose a toy dog as the crew's mascot. The cosmonaut got the stuffed animal as a gift 30 years ago, and he brought it with him to space in 2010 as well. The Soyuz commander also brought toys given to him by his daughters into the capsule.

Speedy trip

The Soyuz crew is scheduled to arrive at the station's Rassvet module at 10:17 p.m. EDT (0217 May 29 GMT). You can watch live coverage of the docking on SPACE.com starting at 9:30 p.m. EDT (0130 May 29 GMT).

It usually takes about two days for a manned Soyuz spacecraft to reach the International Space Station, but this time, the astronauts will make only four orbits of the Earth before docking.

Although many unmanned cargo ships do these kinds of expedited docking procedures regularly, only one other Soyuz crew has flown to the space station using this method.

NASA's Chris Cassidy and Russian cosmonauts Pavel Vinogradov and Alexander Misurkin the three astronauts currently living and working on the space station were the first crew to do the one-day launch and docking when they blasted off to the station in March.

Genetic Engineering Alters Mosquitoes’ Sense of Smell

Posted: at 6:43 pm

In one of the first successful attempts at genetically engineering mosquitoes, HHMI researchers have altered the way the insects respond to odors, including the smell of humans and the insect repellant DEET. The research not only demonstrates that mosquitoes can be genetically altered using the latest research techniques, but paves the way to understanding why the insect is so attracted to humans, and how to block that attraction.

The time has come now to do genetics in these important disease-vector insects. I think our new work is a great example that you can do it, says Leslie Vosshall, an HHMI investigator at The Rockefeller University who led the new research, published May 29, 2013 in the journal Nature.

By disrupting a single gene, we can fundamentally confuse the mosquito from its task of seeking humans. Leslie B. Vosshall

In 2007, scientists announced the completion of the full genome sequence of Aedes aegypti, the mosquito that transmits dengue and yellow fever. A year later, when Vosshall became an HHMI investigator, she shifted the focus of her lab from Drosophila flies to mosquitoes with the specific goal of genetically engineering the insects. Studying mosquitoes appealed to her because of their importance as disease carriers, as well as their unique attraction to humans.

Vosshalls first target: a gene called orco, which her lab had deleted in genetically engineered flies 10 years earlier. We knew this gene was important for flies to be able to respond to the odors they respond to, says Vosshall. And we had some hints that mosquitoes interact with smells in their environment, so it was a good bet that something would interact with orco in mosquitoes.

Vosshalls team turned to a genetic engineering tool called zinc-finger nucleases to specifically mutate the orco gene in Aedes aegypti. They injected the targeted zinc-finger nucleases into mosquito embryos, waited for them to mature, identified mutant individuals, and generated mutant strains that allowed them to study the role of orco in mosquito biology. The engineered mosquitoes showed diminished activity in neurons linked to odor-sensing. Then, behavioral tests revealed more changes.

When given a choice between a human and any other animal, normal Aedes aegypti will reliably buzz toward the human. But the mosquitoes with orco mutations showed reduced preference for the smell of humans over guinea pigs, even in the presence of carbon dioxide, which is thought to help mosquitoes respond to human scent. By disrupting a single gene, we can fundamentally confuse the mosquito from its task of seeking humans, says Vosshall. But they dont yet know whether the confusion stems from an inability to sense a bad smell coming from the guinea pig, a good smell from the human, or both.

Next, the team tested whether the mosquitoes with orco mutations responded differently to DEET. When exposed to two human armsone slathered in a solution containing 10 percent DEET, the active ingredient in many bug repellants, and the other untreatedthe mosquitoes flew equally toward both arms, suggesting they couldnt smell the DEET. But once they landed on the arms, they quickly flew away from the DEET-covered one. This tells us that there are two totally different mechanisms that mosquitoes are using to sense DEET, explains Vosshall. One is whats happening in the air, and the other only comes into action when the mosquito is touching the skin. Such dual mechanisms had been discussed but had never been shown before.

Vosshall and her collaborators next want to study in more detail how the orco protein interacts with the mosquitoes odorant receptors to allow the insects to sense smells. We want to know what it is about these mosquitoes that makes them so specialized for humans, she says. And if we can also provide insights into how existing repellants are working, then we can start having some ideas about what a next-generation repellant would look like.
