NASA test-fired an RS-25 rocket engine today, 08/18/2016 at the Stennis Space Center in Bay St. Louis in Mississippi. The RS-25 is one of four modified space shuttle main engines that will help lift the huge SLS rocket off the ground assisted by two solid rocket boosters.* The RS-25 engines are fueled by liquid oxygen and liquid hydrogen. Combined, the four RS-25 engines on SLS will generate 2…

SDHoS Attends Fundraiser for The Jeremy Fund
Tonight we are not debunking anything. This will come as a surprise to our regular readers, since we normally spend our time refuting the claims of flat-earthers, conspiracy theorists, science deniers and such.
On Tuesday, June 28th, two representatives from Science Denier Hall of Shame attended a pasta dinner fundraiser for The Jeremy Fund.
I would urge all of our readers to take a look at their…

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.

Just as the captains of the fictional 24th century Starfleet blazed a trail among the stars, the space shuttle Enterprise helped pave the way for future space exploration.
Fifty years ago, Star Trek debuted with the USS Enterprise as the main space-faring vessel used in much of the Star Trek universe. As such, the vessel holds a treasured place in the hearts of Star Trek fans and is as much of a character in the show as Kirk and Spock. Over three different series and a total of 14 seasons on TV and 13 feature films, the iterations of Enterprise have captured the imaginations and provided inspiration for its fans across the globe.
This brief history of the shuttle tells the tale of humanity’s first reusable spacecraft. Space shuttles were first built in the late 1970s and were flown in space from 1981 to 2011. Their missions ranged from helping to build the International Space Station to repairing the Hubble Space Telescope.
It’s All In The Name
The first shuttle was originally to be named Constitution, celebrating the country’s bicentennial and was to be unveiled to the public on Constitution Day, Sept. 17, 1976. However, a massive letter-writing campaign by Star Trek fans prompted President Gerald Ford to suggest the change. In the above photo, we see the shuttle Enterprise rolled out in Palmdale, California, with cast members of Star Trek on Sept. 17, 1976.
To Boldly Go …
This circular red, white and blue emblem was the official insignia for the Space Shuttle Approach and Landing Test flights and became a model for future space shuttle mission patch designs, including placing the names of the crew on the patch . The four astronauts listed on the patch are:
Fred Haise., commander of the first crew
Charles Fullerton, pilot of the first crew
Joe Engle, commander of the second crew
Dick Truly, pilot of the second crew
First Impressions
In this image, Enterprise makes its first appearance mated to its boosters as it is slowly rolled to the huge Vehicle Assembly Building (VAB) at Kennedy Space Center. Although she never flew in space, shuttle Enterprise underwent a series of fit and function checks on the pad in preparation for the first launch of its sister craft, Columbia.
Not Meant To Be
Enterprise sits on Launch Complex 39 at Kennedy Space Center undergoing tests after completing its 3.5 mile journey from the VAB. Have you ever wondered why Enterprise never went into space? Converting Enterprise from a training vehicle to space-worthy one was too cost prohibitive, our engineers felt.
Engage
Commander Fred Haise and pilot Charles Fullerton are seen in the cockpit of Enterprise prior to the fifth and final Approach and Landing Test at Dryden Flight Research Center (Armstrong Flight Research Center). The tests were performed to learn about the landing characteristics of the shuttle.
It’s Been An Honor To Serve With You
The Enterprise’s two crews pose for a photo op at the Rockwell International Space Division’s Orbiter assembly facility at Palmdale, California. They are (left to right) Charles Fullerton, Fred Haise, Joe Engle and Dick Truly.
Fair Winds And Following Seas
On July 6, 2012, the Enterprise, atop a barge, passes the Statue of Liberty on its way to the Intrepid Sea, Air and Space Museum, where is now permanently on display.

Successful launch of OrbitalATK Antares rocket at Wallops Flight Facility in Virginia
On Thursday, Sept. 1, U.S. astronauts Jeff Williams and Kate Rubins will conduct the station’s 195th American spacewalk. As part of their activities, the pair will install the first of several enhanced high-definition television cameras that will monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles
Working on the station’s backbone, or truss, Williams and Rubins will retract a thermal radiator that is part of the station’s cooling system.
As was the case for their first spacewalk together on Aug. 19, Williams will be designated as extravehicular crew member 1 (EV1), wearing a spacesuit with a red stripe, while Rubins will be EV2, wearing a suit with no stripes.
Coverage of the spacewalk begins at 6:30 a.m. EDT on Thursday, Sept. 1; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

John Glenn (1921-2016) was all those things and more. When he rocketed into space on Feb. 20, 1962, to become the first American to orbit Earth, the flight set the nation on course to meet ever-more ambitious goals.
The life and career of Senator Glenn eclipses those of many. In spite of his accomplishments, he was a humble and gracious man (and 4-term U.S. senator).
During Glenn’s first flight, a scheduled 30-minute test to determine whether Glenn could fly the capsule manually became a matter of life and death when the automatic system malfunctioned after the first orbit.
“I went to manual control and continued in that mode during the second and third orbits, and during re-entry,” Glenn recalled later. “The malfunction just forced me to prove very rapidly what had been planned over a longer period of time.” Another problem seemed even more serious – telemetry indicated the spacecraft’s heat shield was loose. It seemed possible that Glenn and the spacecraft would be incinerated on re-entry. Glenn left the retrorocket pack in place to steady the heat shield during re-entry. “It made for a very spectacular re-entry from where I was sitting,” he said. Big chunks of the burning material came flying by the window.
He wasn’t sure whether the flaming debris was the rocket pack or the heat shield breaking up. “Fortunately,” he told an interviewer,“ it was the rocket pack – or I wouldn’t be answering these questions.”
In the words of President Obama, who awarded him the Presidential Medal of Freedom in 2012: “When John Glenn blasted off from Cape Canaveral atop an Atlas rocket in 1962, he lifted the hopes of a nation. And when his Friendship 7 spacecraft splashed down a few hours later, the first American to orbit the Earth reminded us that with courage and a spirit of discovery there’s no limit to the heights we can reach together. With John’s passing, our nation has lost an icon and Michelle and I have lost a friend. John spent his life breaking barriers, from defending our freedom as a decorated Marine Corps fighter pilot in World War II and Korea, to setting a transcontinental speed record … The last of America’s first astronauts has left us, but propelled by their example we know that our future here on Earth compels us to keep reaching for the heavens. On behalf of a grateful nation, Godspeed, John Glenn.”
Glenn left the Astronaut Corps in 1964 and resigned from the Marine Corps in 1965. And, after some time in private industry ran for and was elected ti the U.S. Senate in 1974, carrying all 88 counties of Ohio. He was re-elected in 1980 with the largest margin in Ohio history. Ohio returned him to the Senate for a third term in 1986. In 1992 he was elected again, becoming the first popularly elected senator from his state to win four consecutive terms. During his last term he was the ranking member of both the Governmental Affairs Committee and the Subcommittee on Air/Land Forces in the Senate Armed Services Committee. He also served on the Select Committee on Intelligence and the Special Committee on Aging. He was considered one of the Senate’s leading experts on technical and scientific matters, and won wide respect for his work to prevent the spread of weapons of mass destruction.
In 1998, Glenn flew on the STS-95 Discovery shuttle flight, a 9-day mission during which the crew supported a variety of research payloads including deployment of the Spartan solar-observing spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, and Glenn’s investigations on space flight and the aging process.
NASA Administrator Charlie Bolden remembers, “Senator Glenn’s legacy is one of risk and accomplishment, of history created and duty to country carried out under great pressure with the whole world watching.”
Today, we honor him for all that he stood for and continues to stand for – grace under pressure, humility, ability, strength.
Godspeed, John Glenn.
