Extreme heat becomes global health issue

Illustration: Sarah Grillo/Axios
Heat-related deaths around the world increased by 74% from 1980 to 2016, Axios’ Marisa Fernandez writes from a study published yesterday in The Lancet.

More than 356,000 people died from extreme heat-related causes in just nine countries in 2019, a death toll that’s expected to grow as temperatures increase worldwide.

  • 1.3 million deaths were related to cold — a 31% increase since 1990.

Heat stress can lead to stroke, organ and brain damage. A pair of studies out of the University of Washington found it also causes several types of heart disease, diabetes and chronic kidney disease.

Milky Way has a 3,000-light-year-long splinter in its arm, and astronomers don’t know why

(NASA/JPL)

The Sagittarius arm of the Milky Way spirals out of our galaxy’s center, forming a swooping highway of gas that spans tens of thousands of light-years. This highway is dotted with the headlights of billions of stars, all seemingly moving along the same curvy track. But now, astronomers have found something unusual — a “break” in the arm, slashing perpendicularly through the spiral like a splinter poking through a piece of wood.

Spanning about 3,000 light-years, this stellar splinter makes up just a fraction of the Milky Way (which has a diameter of about 100,000 light-years). Still, the newfound break is the first major structure to be discovered disrupting the seemingly uniform flow of the galaxy’s Sagittarius arm, according to a study published online July 21 in the journal Astronomy and Astrophysics.

History & Archaeology
Mass grave from Nazi atrocity discovered in Poland’s ‘Death Valley’

(D. Frymark; Antiquity Publications Ltd.)

Archaeologists in Poland have discovered a mass grave that the Nazis tried to destroy at the end of World War II, a new study finds.

The mass grave, filled with the remains of about 500 individuals, is linked to the horrific “Pomeranian Crime” that took place in Poland’s pre-war Pomerania province when the Nazis occupied the country in 1939. The Nazis killed up to 35,000 people in Pomerania at the beginning of the war, and they returned in 1945 to kill even more people, as well as to hide evidence of the prior massacres by exhuming and burning the bodies of victims.

SpaceX Starlink satellites responsible for over half of close encounters in orbit, scientist says

(SpaceX)

Operators of satellite constellations are constantly forced to move their satellites because of encounters with other spacecraft and pieces of space junk. And, thanks to SpaceX’s Starlink satellites, the number of such dangerous approaches will continue to grow, according to estimates based on available data.

SpaceX’s Starlink satellites alone are involved in about 1,600 close encounters between two spacecraft every week, that’s about 50 % of all such incidents, according to Hugh Lewis, the head of the Astronautics Research Group at the University of Southampton, U.K. These encounters include situations when two spacecraft pass within a distance of 0.6 miles (1 kilometer) from each other.

Chinese satellite got whacked by hunk of Russian rocket in March

(NASA Goddard Space Flight Center)

Yunhai 1-02’s wounds are not self-inflicted.

In March, the U.S. Space Force’s 18th Space Control Squadron (18SPCS) reported the breakup of Yunhai 1-02, a Chinese military satellite that launched in September 2019. It was unclear at the time whether the spacecraft had suffered some sort of failure — an explosion in its propulsion system, perhaps — or if it had collided with something in orbit.

We now know that the latter explanation is correct, thanks to some sleuthing by astrophysicist and satellite tracker Jonathan McDowell, who’s based at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.

Chinese astronomers eye Tibetan Plateau site for observatory project

(NASA JSC)

Chinese astronomers hope to establish a major observatory program on the roof of the world, the Tibetan Plateau, with new research arguing for pristine observing conditions nestled in the uplands.

The analysis focuses on a study site near Lenghu Town in Qinghai Province at an altitude of more than 2.5 miles (4.2 kilometers) and some 1,900 miles (3,000 km) west of Beijing. In the paper, the scientists argue that three years of monitoring shows conditions on par with those at some of the most renowned scientific outposts on Earth.

Fusion experiment breaks record, blasts out 10 quadrillion watts of energy

(Damien Jemison/NIF)

Scientists used an unconventional method of creating nuclear fusion to yield a record-breaking burst of energy of more than 10 quadrillion watts, by firing intense beams of light from the world’s largest lasers at a tiny pellet of hydrogen.

Researchers at the Lawrence Livermore National Laboratory in Northern California said they had focused 192 giant lasers at the National Ignition Facility (NIF) onto a pea-size pellet, resulting in the release of 1.3 megajoules of energy in 100 trillionths of a second — roughly 10% of the energy of the sunlight that hits Earth every moment, and about 70% of the energy that the pellet had absorbed from the lasers. The scientists hope one day to reach the break-even or “ignition” point of the pellet, where it gives off 100% or more energy than it absorbs.

Physicists give weird new phase of matter an extra dimension

(IQOQI Innsbruck/Harald Ritsch)

Physicists have created the first ever two-dimensional supersolid — a bizarre phase of matter that behaves like both a solid and a frictionless liquid at the same time.

Supersolids are materials whose atoms are arranged into a regular, repeating, crystal structure, yet are also able to flow forever without ever losing any kinetic energy. Despite their freakish properties, which appear to violate many of the known laws of physics, physicists have long predicted them theoretically — they first appeared as a suggestion in the work of the physicist Eugene Gross as early as 1957.

World’s most elusive giant squid could be monogamous, female corpse hints

(Miyazu Energy Aquarium)

A female of the world’s largest squid — sometimes called the “kraken” after the mythological sea monster — that was caught off the coast of Japan apparently had just one amorous encounter in her lifetime.

The female had sperm packets from just one male giant squid embedded in her body, which surprised researchers. Because giant squid are solitary creatures that probably run across potential mates only occasionally, scientists expected that females would opportunistically collect and store sperm from multiple males over time.

Lab-made mini brains grow their own sets of ‘eyes’

(Elke Gabriel)

Scientists recently grew mini brains with their own sets of “eyes,” according to a new study.

Organoids are miniature versions of organs that scientists can grow in the lab from stem cells, or cells that can mature into any type of cell in the body. Previously, scientists have developed tiny beating hearts and tear ducts that could cry like humans do. Scientists have even grown mini brains that produce brain waves like those of preterm babies.

Now, a group of scientists has grown mini brains that have something their real counterparts do not: a set of eye-like structures called “optic cups” that give rise to the retina — the tissue that sits in the back of the eye and contains light-sensing cells, according to a statement.

Antarctica’s ‘Doomsday Glacier’ is fighting an invisible battle against the inner Earth, new study finds

(NASA)

West Antarctica is one of the fastest-warming regions on Earth. For evidence, you need look no further than Thwaites Glacier — also known as the “Doomsday Glacier.”

Since the 1980s, Thwaites has lost an estimated 595 billion tons (540 billion metric tons) of ice, single-handedly contributing 4% to the annual global sea-level rise during that time, Live Science previously reported. The glacier’s rate of ice loss has accelerated substantially in the past three decades, partially due to hidden rivers of comparatively warm seawater slicing across the glacier’s underbelly, as well as unmitigated climate change warming the air and the ocean.

Now, new research suggests that the warming ocean and atmosphere aren’t the only factors pushing Thwaites to the brink; the heat of the Earth itself may also be giving West Antarctica’s glaciers a disproportionately nasty kick.

Why this weekend’s Blue Moon is extra rare (and how to see it)

(Gary Hershorn/Getty Images)

The saying “once in a blue moon” is especially pertinent this week: This Sunday (Aug. 22), the full Sturgeon Moon is expected to impress skygazers, particularly because of its “blue” designation.

Typically, the term “Blue Moon” refers to the second full moon within the same month. The last one rose on Oct. 31, 2020, when an eerie Blue Moon lit up the night sky on Halloween. But there’s a lesser-known definition, dating to 1528, which applies to the third full moon in a season with four full moons, according to NASA.

Nerve damage in cornea could be sign of ‘long COVID,’ study hints

(Shutterstock)

Nerve damage and a buildup of immune cells in the cornea may be a sign of “long COVID,” a long-term syndrome that emerges in some people after COVID-19 infection, a new study suggests.

These preliminary results will need to be verified in a larger group of people with long COVID, or COVID-19 long-haulers, as they’re known, an expert told Live Science. But the findings do hint at something scientists already suspected: Some symptoms of long COVID emerge due to peripheral nerve damage, she said.

Will we ever find COVID-19’s ‘Patient Zero?’

Chinese officials have rejected a World Health Organization proposal to investigate the origins of the novel coronavirus that causes COVID-19, raising new questions about whether the world will ever learn when, where and how the coronavirus (SARS-CoV-2) made the leap into humans.

Without Chinese cooperation, scientists will face frustrating gaps in the data that may keep them from identifying the moment the pandemic began. However, the virus itself does hold clues to its own origin. In the coronavirus’s genetic blueprint is a history of where it came from and how long it took to cause the outbreak that led to a global catastrophe.

The real reason CDC is updating their mask guidelines

On Tuesday (July 27), the Centers for Disease Control and Prevention (CDC) updated their mask guidance, saying fully vaccinated people should resume wearing masks in public indoor spaces if there is substantial coronavirus transmission in their area.

Data from the U.S. and other countries indicates that some vaccinated people infected with the delta variant may be contagious and spread the virus to others. Still, breakthrough infections are uncommon and most coronavirus transmission is occurring through unvaccinated individuals, Dr. Rochelle Walensky, the CDC director said.

When a new pathogen emerges, our bodies and healthcare systems are left vulnerable. And when this pathogen causes the outbreak of a pandemic, there’s an urgent need for a vaccine to create widespread immunity with minimal loss of life. So how quickly can we develop vaccines when we need them most? Dan Kwartler describes the three phases of vaccine development. [Directed by Good Bad Habits, narrated by Jack Cutmore-Scott, music by Landon Trimble / Playdate Audio].

For almost a decade, scientists chased the source of a deadly new virus through China’s tallest mountains and most isolated caverns. They finally found it in the bats of Shitou Cave. The virus in question was a coronavirus that caused an epidemic of severe acute respiratory syndrome, or SARS, in 2003. So what exactly is a coronavirus, and how does it spread? Elizabeth Cox explains. [Directed by Anton Bogaty, narrated by Bethany Cutmore-Scott, music by Jarrett Farkas].

Your hands, up close, are anything but smooth. With peaks and valleys, folds and rifts, there are plenty of hiding places for a virus to stick. If you then touch your face, the virus can infect you. But there are two extraordinarily simple ways you can keep that from happening: soap and water, and hand sanitizer. So which is better? Alex Rosenthal and Pall Thordarson investigate.

mRNA Translation (Basic)

Mar 22, 2010  DNA Learning Center

Originally created for DNA Interactive ( http://www.dnai.org ). TRANSCRIPT: When the RNA copy is complete, it snakes out into the outer part of the cell. Then in a dazzling display of choreography, all the components of a molecular machine lock together around the RNA to form a miniature factory called a ribosome. It translates the genetic information in the RNA into a string of amino acids that will become a protein. Special transfer molecules, the green triangles, bring each amino acid to the ribosome. The amino acids are the small red tips attached to the transfer molecules. There are different transfer molecules for each of the twenty amino acids. Each transfer molecule carries a three letter code that is matched with the RNA in the machine. Now we come to the heart of the process. Inside the ribosome, the RNA is pulled through like a tape. The code for each amino acid is read off, three letters at a time, and matched to three corresponding letters on the transfer molecules. When the right transfer molecule plugs in, the amino acid it carries is added to the growing protein chain. Again, you are watching this in real time. And after a few seconds the assembled protein starts to emerge from the ribosome. Ribosomes can make any kind of protein. It just depends what genetic message you feed in on the RNA. In this case, the end product is hemoglobin. The cells in our bone marrow churn out a hundred trillion molecules of it per second! And as a result, our muscles, brain and all the vital organs in our body receive the oxygen they need.

Strange DNA ‘borgs’ discovered in California

(Shutterstock)

Scientists accidentally discovered a mysterious — and unusually large — DNA structure deep in the mud in California wetlands. The structure, known as a “Borg,” likely belongs to a single-celled organism and carries many genes that are unknown to science. It’s not totally clear what these massive strings of DNA do, but they may help supercharge the organisms’ ability to break down chemicals in the soil.

The artificial intelligence (A.I.) company DeepMind says it will soon release a database of the shape of every protein known to science — more than 100 million.

That’s every structured protein in the human body, as well as in 20 research species, including yeast and E. coli bacteria, fruit flies and mice. Prior to the company’s AlphaFold project, which uses artificial intelligence to predict protein shapes, only 17% of the proteins in the human body had their structures identified, according to Technology Review.”It looks astonishingly impressive,” Tom Ellis, a synthetic biologist at Imperial College London, told Technology Review.

CURIOUS CREATURES
Horny sponges that lived nearly 1 billion years ago may be the earliest animals on Earth

(Elizabeth Turner, Laurentian University)

That sea sponge hanging in your shower may be able to trace its evolutionary lineage to nearly a billion years ago, according to fossils that could be the oldest examples of animal life on Earth.

The 890-million-year-old fossils of what may be ancient sponges were found in Canada’s Northwest Territories, and their tiny and delicately branching tendrils are invisible to the naked eye. But under a microscope, the preserved organic tissue revealed a mesh-like structure that was strikingly similar to that of skeleton fibers in modern bath sponges, which are part of a soft-bodied-sponge group known as keratose demosponges, or horny sponges.

Ignoring climate change will yield ‘untold suffering,’ panel of 14,000 scientists warns

(NASA)

Nearly 14,000 scientists have signed a new climate emergency paper, warning that “untold suffering” awaits the human race if we don’t start tackling global warming head-on, effective immediately.

Earth’s vitals have only deteriorated over the last two years, with 18 of the report’s 31 categories showing new all-time record highs or lows, the authors wrote. Greenhouse gas emissions are at an all-time high, while glacial ice thickness is at its lowest point in 71 years of record keeping, the report found. The world is richer than it’s ever been (measured by global GDP), while the sky is more polluted than ever (measured by carbon dioxide, methane and nitrous oxide concentrations in the atmosphere).

AMAZING EARTH
Iceland may be the tip of a sunken continent

Iceland may be the last exposed remnant of a nearly Texas-size continent — called Icelandia — that sank beneath the North Atlantic Ocean about 10 million years ago, according to a new theory proposed by an international team of geophysicists and geologists.

The theory goes against long-standing ideas about the formation of Iceland and the North Atlantic, but the researchers say the theory explains both the geological features of the ocean floor and why Earth’s crust beneath Iceland is so much thicker than it should be. Outside experts not affiliated with the research told Live Science they are skeptical that Icelandia exists based on the evidence collected so far.

The End of One Drive by Perseverance on the Floor of Jezero Crater

Jul 21, 2021

This image of a Martian vista in Jezero Crater, made from smaller individual images, was taken by NASA’s Perseverance rover on July 3, 2021 (the 131th sol, or Martian day, of its mission). The rover’s tracks from its autonomous drive that day are visible on the right. The images that compose the larger mosaic came from the rover’s Navigation Cameras and were processed to enhance the contrast.

Perseverance has been exploring the floor of Jezero since it landed on Feb. 18, 2021.

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

This video from July 1, 2021 (the 130th sol, or Martian day, of its mission), shows scenes from the longest autonomous drive yet for NASA’s Perseverance Mars rover, which landed on Feb. 18, 2021. At the beginning of the traverse on Sol 130, the rover’s engineers manually drove past NASA’s Ingenuity Mars Helicopter. Then the rover began driving autonomously, avoiding hazards and traveling 358 feet (109 meters) on its own.

One of the rover’s Navigation Cameras took the images about once every 16 feet (5 meters). They were processed to enhance the contrast.

Perseverance Scouts First Sampling Location

Jul 21, 2021

CONTEXT IMAGE

This image shows the area on Mars from which NASA’s Perseverance rover will collect its first rock sample. Scientists are particularly interested in the flat stones that appear light-colored (informally called “paver rocks”). The Perseverance team has nicknamed this area in Mars’ Jezero Crater the “Crater Floor Fractured Rough” area.

The 28 individual images that were combined to make the larger main image were taken by the rover’s Mastcam-Z right-eye camera on July 8, 2021 (the 136th sol, or Martian day, of the mission). The images have been calibrated and are presented in natural color, simulating the approximate view that we would see with our own eyes if we were there.

A second version (Figure 1) combines 56 individual images from the rover’s Mastcam-Z left-eye and right-eye cameras on the same day. The images have been calibrated and are presented as a natural color anaglyph (for red-blue glasses), simulating the approximate 3D and color view that we would see with our own eyes if we were there.

The Mastcam-Z investigation is led and operated by Arizona State University in Tempe, working in collaboration with Malin Space Science Systems in San Diego, California, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Neils Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets.

Witness Tube in Perseverance Sample Caching System

Jul 21, 2021

Click here for animation

As part of its search for signs of ancient life on Mars, Perseverance is the first rover to bring a sample caching system to the Red Planet that will package promising samples for return to Earth by a future mission. This series of images shows NASA’s Perseverance rover inspecting and sealing a “witness” sample tube on June 21, 2021 (the 120th sol, or Martian day, of the mission), as it prepares to collect its first sample of Martian rock and sediment.

Witness tubes are similar to the sample tubes that will hold Martian rock and sediment, except they have been preloaded with a variety of materials that can capture molecular and particulate contaminants. They are opened on the Martian surface to “witness” the ambient environment near sample collection sites. With samples returned to Earth in the future, the witness tubes would show whether Earth contaminants were present during sample collection. Such information would help scientists tell which materials in the Martian samples may be of Earth origin.

The sampling system’s dedicated camera, the Cachecam, captured these images.

SuperCam Image of Artuby

Jul 21, 2021


Figure 1


Figure 2

Click on images for larger versions
NASA’s Perseverance rover took these zoomed-in images of a layered outcrop (just below center of image) nicknamed “Artuby” on June 17, 2021 (the 116th sol, or Martian Day, of its mission), from a little more than a third of a mile (615 meters) away. This mosaic is made up of three images taken by the Remote Microscopic Imager (RMI), part of the rover’s SuperCam instrument. Each circular image has a field of view of 37.73 feet (11.50 meters) at this distance. The images were combined using an algorithm that weights the image centers.

The outcrop shows evidence of being formed in an ancient lake. The feature is in the ‘Verdon’ quadrangle of Mars’ Jezero Crater, south of the landing site. Artuby is the name of a river in southern France.

One version (Figure 1) uses a Gaussian color stretch to make it easier to see differences among the colors. Another version (Figure 2) shows natural color, simulating the approximate view that we would see with our own eyes if we were on Mars.

Perseverance has been exploring the floor of Jezero Crater since it landed on Feb. 18, 2021.

SuperCam is led by Los Alamos National Laboratory in New Mexico, where the instrument’s Body Unit was developed. That part of the instrument includes several spectrometers as well as control electronics and software.

The Mast Unit, including the RMI used for these images, was developed and built by several laboratories of the CNRS (the French research center) and French universities under the contracting authority of Centre National d’Etudes Spatiales (CNES, the French space agency).

Perseverance Looks Back After a Long Autonomous Drive

Jul 21, 2021

NASA’s Perseverance Mars rover looks back toward its tracks on July 1, 2021 (the 130th sol, or Martian day, of its mission), after driving autonomously 358 feet (109 meters) – its longest autonomous drive to date. Taken by one of the rover’s Navigation Cameras, the image has been processed to enhance the contrast.

Figure 3
Click on images for larger versions

This wide view of Mars’ Jezero Crater was taken by NASA’s Perseverance rover on July 15, 2021 (the 143rd sol, or Martian day, of its mission). The rover has driven nearly a mile (1.5 kilometers) south of its landing site, “Octavia E. Butler Landing,” into a region the team has nicknamed the “Crater Floor Fractured Rough” unit. The stones that appear light-colored and flat in this image (Figure 1) are informally referred to as the “paver rocks” and will be the first type from which Perseverance will collect a sample for planned return to Earth by subsequent missions. Small hills to the south of the rover and the sloping inner walls of the Jezero Crater rim fill the distant background of this view.

Five images from the rover’s Mastcam-Z instrument were calibrated and combined to make this mosaic. One version (main image), presented in natural color, simulates the approximate view that we would see with our own eyes if we were there. Another version (Figure 2) is presented in enhanced color to exaggerate the subtle red, green, and blue color differences among the materials in this scene.

A third version (Figure 3) combines the five images from both the left and right Mastcam-Z cameras into an anaglyph (for red-blue glasses) that simulate a 3D view of the scene in enhanced color.

Perseverance has been exploring the floor of Jezero since landing on Feb. 18, 2021.

The Mastcam-Z investigation is led and operated by Arizona State University in Tempe, working in collaboration with Malin Space Science Systems in San Diego, California, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Neils Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets.

The robotic arm on NASA’s Perseverance rover reached out to examine rocks in an area on Mars nicknamed the “Cratered Floor Fractured Rough” area in this image captured on July 10, 2021 (the 138th sol, or Martian day, of its mission). The image was taken by one of the rover’s hazard cameras. An additional set of images from July 10-12 have been compiled into a GIF.

Scientists are particularly interested in the flat rocks that appear light in color (nicknamed “paver rocks”). This image was processed to enhance contrast.

WATSON Views Foux

Jul 20, 2021

NASA’s Perseverance Mars rover took this close-up of a rock target nicknamed “Foux” using its WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera, part of the SHERLOC instrument on the end of the rover’s robotic arm. The image was taken July 11, 2021, the 139th Martian day, or sol, of the mission. The area within the camera is roughly 1.4 by 1 inches (3.5 centimeters by 2.6 centimeters).

NASA’s Jet Propulsion Laboratory built and manages operations of Perseverance and Ingenuity for the agency. Caltech in Pasadena, California, manages JPL for NASA. WATSON was built by Malin Space Science Systems (MSSS) in San Diego and is operated jointly by MSSS and JPL.

PIXL’s First Chemical Maps

Jul 20, 2021

This data shows chemicals detected within a single rock on Mars by the Planetary Instrument for X-ray Lithochemistry (PIXL), one of the instruments on the end of the robotic arm aboard NASA’s Perseverance Mars rover. PIXL allows scientists to study where specific chemicals can be found within an area as small as a postage stamp.

The Little (Mars) Helicopter That Could

Ingenuity, the helicopter that arrived on the Red Planet on the Mars Perseverance rover, has made nine flights on Mars. Ingenuity’s historic achievement is the first powered helicopter flight on a terrestrial body other than Earth.

According to Håvard F. Grip, Ingenuity Chief Pilot, and Ken Williford, Perseverance Deputy Project Scientist, Flight 9, which occurred in July 2021, was unlike the flights that came before it. It broke our records for flight duration and cruise speed, and it nearly quadrupled the distance flown between two airfields. But what really set the flight apart was the terrain that Ingenuity had to negotiate during its 2 minutes and 46 seconds in the air – an area called “Séítah” that would be difficult to traverse with a ground vehicle like the Perseverance rover. This flight was also explicitly designed to have science value by providing the first close view of major science targets that the rover will not reach for quite some time.

But the Mars Perseverance team didn’t do it alone. A team of helicopter experts from our Ames Research Center in California assisted the Ingenuity team in making sure the technology demonstrator had the best chance for success in flying in the super thin atmosphere of the Red Planet. Learn more.

This image was captured by Mars Perseverance rover using its Left Mastcam-Z Camera, composed of a pair of cameras located high on the rover’s mast, on Jun. 15, 2021 (Sol 114).

Velshi: We Can Focus On Climate Change & Still Marvel At Space Travel

Jul 17, 2021  MSNBC

There are valid criticisms of the commercial space industry. But let’s separate the criticisms of Bezos, Branson, and Musk from the remarkable achievements we are witnessing. Where the critics are wrong is in thinking last week’s Virgin Galactic launch and next week’s Blue Origin launch aren’t important and meaningful advances. I share your sense of urgency about social justice, democracy, climate change, public education, poverty eradication and higher wages. We can fix all of those things and still marvel at a space launch and dream about traveling to space or being the engineers, scientists and pilots who get us there.» Subscribe to MSNBC: http://on.msnbc.com/SubscribeTomsnbc
