According to Gian Paolo Bassi, CEO, SOLIDWORKS, Dassault Systemes, new space exploration devices will further expand our knowledge about the universe.

"We are working closely with JPL engineers to build a space exploration device that will be faster than any other machine of its kind of previous generation and will be able to carry heavier payloads," Bassi addressed the jam-packed Los Angeles Convention Centre as he kicked-off the four-day SOLIDWORKS World 2017 conference here on Monday.

"In order to safeguard our Earth from an asteroid impact in the future, we are also working with NASA to develop a planetary space defense system that can alert us in such threat in advance," Bassi told the gathering in the city of entertainment which was inundated with rain since morning.

Dassault Systemes is also working with the California-based aerospace manufacturer and space transport services company SpaceX on an ambitious hyperloop transportation project.

Proposed by SpaceX founder Elon Musk in 2013, the Hyperloop system envisages mass transportation at a speed of up to 760 miles (nearly 1300 km) per hour via low-pressure tubes.

"It means that once in use, the hyperloop pod ride will take you to San Francisco from Los Angeles in flat 35 minutes. We are working with engineers to design the low-flying vehicle," Bassi noted.

Last week, the Hyperloop competition pitted 27 research teams against each other for the chance to test-drive their model pods in a test tube built by SpaceX in California.

Following the competition, SpaceX released a video which takes viewers on a trip through the 1.25km tube, showing what a ride in a Hyperloop pod might be like.

Students from Massachusetts Institute of Technology, Munich Technical University and Delft University of Technology finally received the chance to send their pods for a test drive to see whose model was most impressive.

"Innovation is about experiences that we are creating for our customers and space research is one of those," Bassi said.

Not just space research, the 3D design solutions are also helping baby toy manufacturers build innovative toys, guitar makers develop new-age electric guitars and magicians create mind-blowing illusions to leave their audience speechless.

Being attended by over 5,000 engineers and designers from around the globe, the four-day event is organized by Dassault SystAmes, the 3DEXPERIENCE Company and a world leader in 3D design software.

Over 120 exhibitors are displaying new technologies and products amid 200 interactive training sessions at the annual SOLIDWORKS World 2017.

Space. It wont be an exaggeration to say that almost everything in the vast cosmic void that envelopes Earth will kill us in the blink of an eye. This wont be much of a problem if we were a firmly Earth-bound species, but, as Carl Sagan once presciently remarked:We have a basic responsibility to our species to venture to other worlds.

Previous studies have already shown that long-term exposure to the microgravity environment of space impairs astronauts vision, atrophies their muscles, and even causes changes in gene expression and chromosome length.

Now, a new NASA-funded study published in the latest edition of the journal Nature Microgravity has detailed the impact spaceflight has on the shape of astronauts brains. The researchers, whoexamined structural MRIs in 12 astronauts who spent two weeks as shuttle crew members and 14 who spent six months on the International Space Station, found noticeable changes in gray matter in different parts of the brain.

Specifically, MRIs taken before and after spaceflight revealed that the volume of gray matter both increased and decreased, and the extent of the changes depended on the length of time spent in space.

We found large regions of gray matter volume decreases, which could be related to redistribution of cerebrospinal fluid (CSF) in space, lead author Rachael Seidler from the University of Michigan said in a statement released Tuesday. Gravity is not available to pull fluids down in the body, resulting in so-called puffy face in space. This may result in a shift of brain position or compression.

Gray matter, which consists of neuronal cell bodies and unmyelinated axons, is responsible for controlling a variety of functions, including sensory perception, memory formation, decision-making and emotions.

The researchers found that gray matter volume increased in the areas of the brain that control leg movement, which may reflect changes related to the brain learning how to move in microgravity, while in other areas of the brain, gray matter volume decreased due to redistribution of the CSF.

It is important to note that the changes in gray matter volume do not stem from a loss or gain in brain cells. Moreover, it is still not clear what repercussions these changes have on cognition and physical performance in the long term, and whether, once the astronauts are back on Earth, the brain can still use different pathways to compensate for the structural changes caused by spaceflight.

These intriguing findings are observed in a retrospective data set. More carefully controlled prospective studies may shed further light on these changes and their relation to behavioral performance, the researchers concluded in the study.

Space Exploration: Astronauts' Brains Are Changed By Spaceflight, MRI-Based Study Reveals - International Business Times

Astronaut Stephanie Wilson, shown here training for a Space Shuttle flight, visited the International Space Station several times.

A few weeks ago, Hidden Figures, the story about African-American women who helped get Apollo astronauts to the Moon, was overtaking and holding the box office lead. This real-life story of Black history in the Space Age supplanted the science fiction space adventure Rogue One and is holding its own, which should be no surprise. But the story and its success is a surprise. Hidden Figures revealed a part of NASA history that had been left out of the story we usually tell about the Space Age. Space exploration has been about people as well as about machines, and Katherine Johnson, Dorothy Vaughn, and Mary Jackson didnt make it into the history books until recently. History books got that wrong, until now.

At the same time this film was telling this eye-opening story of Black history, theHuffington Post,Yahoo!,Economic Times,and others ran stories about the first African-American International Space Station crew member, who is scheduled to launch for an extended stint aboard the station in 2018. These and other media outlets claimed that Jeanette Epps will be the first African-American sent to the space station or to board ISS.

The media got that wrong.

This is probably due to a misunderstanding about how ISS crew rotation works. Reporters, likely unfamiliar with space exploration, probably didn't bother to look carefully at the announcement on NASA's website, or didn't understand the difference between an Expedition crew aboard the space station and a Soyuz or Shuttle crew going to the space station. The shuttle flew to the International Space Station (ISS) for years, carrying astronauts back and forth on short missions of a week or two to deliver supplies or to help with repairs. Some members of those shuttle crews joined a space station crew to stay aboard for longer stints. These longer-term Expedition crews were formed in a carefully orchestrated scheduled of overlaps and swap-outs thats been going on since November 2, 2000.

Just as many of us are surprised to know that African-American women mathematicians were calculating spacecraft trajectories fifty years ago, we might mistakenly assume that African-Americans have not been actively contributing to space exploration as astronauts these last thirty years. Epps will fly up as part of a Soyuz crew and remain as part of an Expedition crew, and that is a terrific first. But she wont be the first African-American to float through the hatch into ISS.

African-American astronaut Stephanie Wilson flew to and boarded ISS three separate times over four years. In 2007, Wilson was part of the STS-120 shuttle crew that also included Daniel Tani. She returned to Earth Mark Hamills light saber from Star Wars, which had been carried aboard for the films thirtieth anniversary. Tani, on the other hand, became part of the space stations sixteenth Expedition. He stayed on orbit almost four months and had no way to return home to be with his family when his mother died. Thats among the risks Epps will face in 2018: the inability to return home any time soon.

To be sure, all the humans who went to the moon were white men. Even in the early days of Americas space programs, however, Ed Dwight was picked as an astronaut candidate. He faced harsh racism and, after the assassination of President Kennedy, decided not to join the astronaut corps. Though he never flew to space either, Robert Henry Lawrence Jr. became the first Black astronaut in 1967, when he joined the Manned Orbital Laboratory program, a sort of spy-in-the-sky idea. By the time that program was cancelled and some of its astronauts switched to NASA, Lawrence had died when his ejection seat malfunctioned during an aborted test flight of a supersonic aircraft at Edwards Air Force Base.

In the wake of these small first steps, the astronaut group chosen in 1978 became the giant forward for NASA that shaped the space shuttle crews and future astronaut selection for decades to come. As NASA moved toward the first shuttle launch, this class included six women, an Asian-American man, and three African-American men: Guion Bluford Jr., Ronald McNair, and Frederick Gregory. In 1983, on the eighth shuttle mission, Bluford became the first of these three to travel beyond Earths atmosphere. He went on to fly four more missions.

But the first Black person to travel to space wasnt Bluford. A Cuban of African descent had done that aboard a Russian Soyuz spacecraft three years earlier. Arnaldo Tamayo Mndez was part of the Intercosmos program. He flew to Salyut 6 in 1980, where he and his fellow cosmonaut conducted experiments on the causes of space sickness and also on sucrose crystallization in low gravity in hopes of improving Cubas sugar industry.

From that more inclusive NASA astronaut class of the late 1970s, McNair flew aboard the shuttle twice. He died on his second flight, on January 28, 1986, when the space shuttleChallengerbroke apart as the nation watched on television. Gregory watched the tragedy unfold from Mission Control, for he was the astronaut on the ground keeping track of the weather that morning. McNair left an amazing legacy in a scholarship program that helps prepare first-generation and traditionally underrepresented undergraduate students for doctoral study.

In 1989, Gregory, a pilot, became the first African-American to command a spaceflight. That was his second of three missions. The increasing inclusivity of NASAs astronaut corps, in fact, has made it an eclectic, incredibly agile group that adapted to the changing role of the space shuttle and continues to adapt to Soyuz missions and planned exploration to Mars.

The first African-American woman to travel to space was not Epps or even Wilson but, rather, Mae Jemison. Jemison, a physician, served in the Peace Corps before she joined the astronaut corps in 1987. She applied to be an astronaut after she saw Sally Ride become the first American woman in space. Jemison names Nichelle Nichols, who played Uhura on Star Trek, as her role model, for Uhura was the African-American woman spacefarer with whom many of us grew up. During that flight, she honored Uhura by starting each of her work shifts by saying, Hailing frequencies open. The 25th anniversary of Jemisons flight aboard Endeavour occurs this year.

Several African-American astronauts have visited the space station. Robert Curbeam was the first, in 2001, and Alvin Drew was the last to fly there aboard shuttle, on Discoverys last mission in 2011. During that flight, he performed a spacewalk. Though he was the two-hundredth person to do that, he wasnt the first African-American. That first belongs to Bernard Harris Jr., who walked in space back in 1995. Curbeam, in fact, made seven spacewalks over his NASA career, the most of any African-American.

All of NASA, in fact, is headed up by an African-American astronaut. Charlie Bolden traveled to space four times before becoming NASA Administrator in 2009 and serving through the end of President Obamas administration.

The International Space Station has been continuously inhabited for more than sixteen years. Currently, six astronauts are circling overhead, onboard ISS as members of the Expedition 50 crew. Their earthly homes are Russia (three), the United States (two), and France (one), making this very much an international space station. Those of us on the planets surface can check to see what the crew has planned for every day they are on station. We can also see ISS traverse the night sky with your own eyes, with instructions from NASAs Spot The Station website.

To mistakenly think that Jeanette Epps would be the first African-American to visit the station shows a lack of understanding of the long-standing contributions of African-Americans to our nations achievements. To understand that Epps will be the first African-American to be part of an Expedition crew is to celebrate her achievement as part of the rich, ongoing history of this country in the largest sense and of spacefaring and ISS in particular. Her planned mission signals that firsts still remain to be achieved and that theres no reason to think that a crew to Mars shouldnt be inclusive and stronger for it. So, mark your calendar for May 2018, when Epps will be onboard ISS, zooming across the heavens inside that spark of light.
