Return Of Flat Out Stupid: SpaceX Edition Remember 'Russianvids'? He Was The Fellow That Tried To Disprove

Ever have to talk to an #evolution denier? Seems that this is usually how it goes.

Living and Working Aboard Station

 Join us on Facebook Live for a conversation with astronaut Kate Rubins and the director of the National Institutes for Health on Tuesday, October 18 at 11:15 a.m. ET.

Astronaut Kate Rubins has conducted out of this world research aboard Earth’s only orbiting laboratory. During her time aboard the International Space Station, she became the first person to sequence DNA in space. On Tuesday, she’ll be live on Facebook with National Institute of Health director Francis Collins, who led the effort to map the human genome. You can submit questions for Kate using the hashtag #SpaceChat on Twitter, or during the live event. Here’s a primer on the science this PhD astronaut has been conducting to help inspire your questions: 

Kate has a background in genomics (a branch of molecular genetics that deals with the study of genomes,specifically the identification and sequencing of their constituent genes and the application of this knowledge in medicine, pharmacy,agriculture, and other fields). When she began her tenure on the station, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbital platform.

“I [have a] genomics background, [so] I get really excited about that kind of stuff,” Rubins said in a downlink shortly after reaching the one billion base pairs sequenced goal.

NASA and Its Partnerships

We’re not doing this alone. Just like the DNA sequencing was a collaborative project with industry, so is the Eli Lilly Hard to Wet Surfaces investigation. In this experiment aboard the station, astronauts will study how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth. Learn more about what we and our partners are doing:

With our colleagues at the Stanford University School of Medicine, we’re also investigating the effects of spaceflight on stem cell-derived heart cells, specifically how heart muscle tissue, contracts, grows and changes  in microgravity and how those changes vary between subjects. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions. Learn more:

It’s Not Just Medicine

Kate and her crew mates have also worked on the combustion experiments.

Kate has also worked on the Bigelow Expandable Activity Module (BEAM), an experimental expandable capsule that docks with the station. As we work on our Journey to Mars, future space habitats  are a necessity. BEAM, designed for Mars or other destinations, is a lightweight and relatively simple to construct solution. Kate has recently examined BEAM, currently attached to the station, to take measurements and install sensors.

Kate recently performed a harvest of the Plant RNA Regulation experiment, by removing seed cassettes and stowing them in cold stowage.

The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions. Read more about the experiment:

NASA Astronaut Kate Rubins is participating in several investigations examining changes in her body as a result of living in space. Some of these changes are similar to issues experienced by our elderly on Earth; for example, bone loss (osteoporosis), cardiovascular deconditioning, immune dysfunction, and muscle atrophy. Understanding these changes and how to prevent them in astronauts off the Earth may help improve health for all of us on the Earth. In additional, the crew aboard station is also working on more generalized studies of aging.

How Will We Safely Send the First Humans to the Red Planet?

We’ve been exploring the Red Planet for over 50 years – Mariner 4 launched on this day (Nov. 28) in 1964 and took the first photos of Mars from space the following summer.

We first explored the surface 40 years ago (Viking, 1976) and have had a continuous scientific presence on Mars for nearly 20 years, starting with the landing of the Pathfinder lander and Sojourner rover on July 4, 1997.

We currently have three orbiters – MAVEN, MRO and Mars Odyssey – and two rovers – Curiosity and Opportunity – actively exploring Mars.

These robotic explorers have already taught us a lot about the Red Planet, and future missions will teach us even more about how humans can live and work on the surface.

After sending humans on space exploration missions for the last 50 years, we have gained the experience and knowledge to send the first people to Mars. We are working across all areas to prepare for that historic day and want to share our progress with you. 

Building the ride to Mars: NASA’s Space Launch System.

Our ride to Mars, the Space Launch System, is being built right now to meet the challenges of exploring deep space. When it comes to our journey to Mars and beyond, there are no small steps. Our video series by the same name breaks down those steps to show how SLS will send missions to the Red Planet.

Living on the Space Station will help humans live safely on Mars.

New crew members of Expedition 50 will soon conduct more than 250 experiments on the International Space Station. More than 2,000 experiments have already been done! 

Experiments in fields such as biology, Earth science, physical sciences and human research are helping us unlock the knowledge needed to enable humans to live in space for long durations. If you missed the recent launch, check out NASA TV for a replay.

Testing Orion helps crew live and work in space and get home safely.

Scheduled to launch atop the Space Launch System rocket for the first time in 2018, an uncrewed Orion will travel farther into space than any spacecraft built for humans has ever gone before. When Orion returns to Earth, splashing down into the Pacific Ocean, it will take a landing and recovery group to safely return the capsule and crew back to land. A variety of testing on the ground, including to structures and parachutes, is helping make sure Orion can safely carry crew to new destinations in the solar system.

In late October, this recovery group, including NASA’s Ground Systems Development and Operations Program, the U.S. Navy, U.S. Air Force and contractor employees, completed its fifth successful practice run to recover Orion aboard the USS San Diego. 

We’re using high resolution imagery from the Mars Reconnaissance Orbiter to learn more about potential landing sites for a human mission.

Who knows what surprises the Red Planet holds?

Our Curiosity Rover has discovered all kinds of interesting Mars features including meteorites. How do you learn more about a meteorite? Zap it with lasers, of course.

This golf-ball-sized, iron-nickel meteorite was recently found on Mars where ancient lakebed environments once existed. Named “Egg Rock” for the area in which it was found, it is the first meteorite to be examined using a laser-firing spectrometer.

By studying the conditions on Mars with vehicles like Curiosity, scientists are able to help prepare future astronauts to live on Mars.

How do you prepare the tallest rocket ever built for its first launch?

Another important component in successfully launching the Space Launch System rocket and Orion spacecraft on a Journey to Mars is the infrastructure work being done by our Ground Systems Development and Operations Program at Kennedy Space Center.

While efforts at our Vehicle Assembly Building continue, we hope you’ll be making your plans to join us at the launch pad for the first flight of SLS with Orion in 2018!

Preparing for a human journey to Mars

The next Mars rover will launch in 2020, and will investigate a region of Mars where the ancient environment may have been favorable for microbial life, probing the Martian rocks for evidence of past life. 

It will collect samples and cache them on the surface for potential return to Earth by a future mission. Mars 2020 will also conduct the first investigation into the usability and availability of Martian resources, including oxygen, in preparation for human missions.

Jeff Williams: Record Breaker

Astronaut becomes U.S. record holder for most cumulative time in space!

The Olympics are over, but Americans are STILL breaking records. NASA astronaut Jeff Williams just broke Scott Kelly’s record of 520 cumulative days spent in space. When Williams returns to Earth on Sept. 5, he will have racked up 534 days in space. To celebrate this amazing achievement, here are some of the best images taken during his four spaceflights.

STS-101 Atlantis:

During May 2000, Williams made his first spacewalk during space shuttle Atlantis’ STS-101 mission. On this 10-day mission, Williams’ first spacewalk lasted nearly seven hours. He is pictured here outside the space station.

Expedition 13:

Williams experienced his first long-duration mission in 2006, when he served as flight engineer for Expedition 13 space station mission. During his time in orbit, he performed two spacewalks, saw the arrival of two space shuttle missions and resumed construction of the orbiting laboratory during his six-month tour. While on one of those spacewalks, Williams took this selfie.

Expedition 21/22:

Williams returned to space for another six-month mission in 2009 as a flight engineer on Expedition 21 and commander of Expedition 22. During that time, he hosted the crews of two space shuttle missions. The U.S.-built Tranquility module and cupola were installed on station. Here is an image of the then newly installed cupola.

Expedition 47/48:

This time around, Williams has been onboard the space station since March 2016, where he served as flight engineer for Expedition 47 and now commands Expedition 48. With over 7,000 retweets on Williams’ photo of an aurora from space, his Twitter followers were clearly impressed with his photography skills.

It's about time we explained why Science Denier Hall of Shame exists. Here's the short answer.

Homeopathy Death Merchant ‘True Cancer Remedies’ This is precisely the type of thing we've been trying to shine a light on. This is a woo-peddler that actively encourages people to avoid medical care in favor of homeopathic 'self help'.

This unprocessed image shows features in Saturn’s atmosphere from closer than ever before. The view was captured by our Cassini spacecraft during its first Grand Finale dive between the planet and its rings on April 26, 2017.

As Cassini dove through the gap, it came within about 1,900 miles (3,000 kilometers) of Saturn’s cloud tops (where the air pressure is 1 bar – comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.
