First Female Cosmonaut Arrives on Station as Part of Expedition 41/42The ISS saw the arrival of three new crew members this week. Russian cosmonauts Elena Serova and Alexander Samojutyaev, along with NASA astronaut Bruce Wilmore joined NASA astronaut Reid Wiseman, ESA astronaut Alexander Gerst, and Russian cosmonaut Maxim Suraev on station. Serova is only the fourth female cosmonaut to fly inspace and one of only 18 females to be selected as cosmonauts since 1961. These numbers are in stark contrast to the United States, who has had over 40 women selected as astronauts, and even had two female commanders of the space station — Peggy Whitson (2007-2008) and Sunny Williams (2012). Elena tried to make light of her historic mission, by saying she thought of this as just work, her job is space. However, she did recognize its significance and what it means for Russian women. Elena is an accomplished engineer and even worked in Russian Mission Control prior to being selected for the cosmonaut corps in 2006. She is a graduate of the esteemed Moscow Aviation Institute and was selected as part of the Expedition 41/42 crew back in 2011.Serova is described as being the first female cosmonaut selected based on her skills and merits, and boy is she qualified. Hopefully, she will have a long history with the space program. Despite being highly qualified, Elena had to suffer through countless questions at pre-launch briefings about what her hair and make-up regime would be on station. She was quick to fire back at reporters, asking them why don’t ask her male comrades what they were going to do with their hair. Serova joins a small club of high-flying Russian women. This groups includes the first woman in space Valentina Tereshkova (1963); the first woman to perform a space walk, Sveltlana Savitskaya (1992, 1994); and the first woman to fly a long-duration mission and the only female cosmonaut to fly on shuttle, Yelena Kondakova (1994-1995).In November, Serova will be joined by another female astronaut, Italian astronaut Samantha Cristoferetti. Samantha is Europe’s third female astronaut behind Helen Sharman in 1991, and Claudie Haignere in 2001.Image & Source Credit: NASA/ESA/Roscosmos View high resolution

Next Generation Spacesuit like Second Skin

Scientists from MIT have designed a next-generation spacesuit that acts practically as a second skin, and could revolutionize the way future astronauts travel into space. (Photo : Jose-Luis Olivares/MIT)
Astronauts are used to climbing into conventional bulky, gas-pressurized spacesuits, but this new design could allow them to travel in style. Soon they may don a lightweight, skintight and stretchy garment lined with tiny, muscle-like coils. Essentially the new suit acts like a giant piece of shrink-wrap, in which the coils contract and tighten when plugged into a power supply, thereby creating a “second skin.”
"With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space," lead researcher Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, said in astatement.
"We want to achieve that same pressurization, but through mechanical counterpressure - applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration."
Newman, who has worked for the past decade on a design for the next-generation spacesuit, describes the new garment in detail in the journal IEEE/ASME: Transactions on Mechatronics.
The MIT BioSuit’s coils, which are a main feature of the outfit, are made from a shape-memory alloy (SMA). At a certain temperature, the material can “remember” and spring back to its engineered shape after being bent or misshapen.
Skintight suits are not a novel idea, but in the past scientists have always struggled with the question: how do you get in and out of a suit that is so tight? That’s where the SMAs come in, allowing the suit to contract only when heated, and subsequently stretched back to a looser shape when cooled.
Though the lightweight suit may not seem at first like it can withstand the harsh environment that is outer space, Newman and his colleagues are sure that the BioSuit would not only give astronauts much more freedom during planetary exploration, but it would also fully support these space explorers.
Newman and his team are not only working on how to keep the suit tight for long periods of time, but also believe their design could be applied to other attires, such as athletic wear or military uniforms.
"An integrated suit is exciting to think about to enhance human performance," Newman added. "We’re trying to keep our astronauts alive, safe, and mobile, but these designs are not just for use in space."


Scuse you, Dava Newman is a FEMALE professor at MIT.

The discovery of a strangely branched organic molecule in the depths of interstellar space has capped a decades-long search for the carbon-bearing stuff.
The molecule in question — iso-propyl cyanide (i-C3H7CN) — was spotted in Sagittarius B2, a huge star-making cloud of gas and dust near the center of the Milky Way, about 27,000 light-years from the sun. The discovery suggests that some of the key ingredients for life on Earth could have originated in interstellar space.

NGC 4449
NGC 4449 is an irregular dwarf galaxy located about 12.5 million light years away towards the constellation Canes Venatici, the Hunting Dogs. It is about the size of the Large Magellanic Cloud, a satellite galaxy of the Milky Way, and is currently undergoing a burst of star formation.
Ngc 4449 is also the first dwarf galaxy with a noticable tidal star stream, seen in this image on the lower right. The inset in this image shows the stream in red giant stars. This stream is made from the remains of a smaller galaxy, disrupted by the gravitational forces and now in the process of merging with NGC 4449, probably causing the current starburst. Small galaxies often have large halos of dark matter, so by studying the system astronomers can learn about how the presence of dark matter affects galactic merging.

Astronomy Picture of the Day: January 21st, 2003

In the vast Orion Molecular Cloud complex, several bright blue nebulas are particularly apparent. Pictured above are two of the most prominent reflection nebulas - dust clouds lit by the reflecting light of bright embedded stars. The more famous nebula is M78, on the upper right, cataloged over 200 years ago. On the lower left is the lesser known NGC 2071. Astronomers continue to study these reflection nebulas to better understand how interior stars form. The Orion complex lies about 1500 light-years distant, contains the Orion and Horsehead nebulas, and covers much of the constellation of Orion.
