NASA has replaced an astronaut set to launch to the International Space Station (ISS) in June with a backup.
Jeanette Epps, who was set to become the first African American crew member on the space station, has been reassigned to the Astronaut Office at NASA’s Johnson Space Center, the space agency announced. She will be considered for future flights.
“Serena Auñón-Chancellor, who previously was assigned to Expedition 58/59, has been reassigned to the Expedition 56/57 crew, launching in June,” NASA said in a press release. ” Anne McClain, a member of the 2013 astronaut class, will fly on the Expedition 58/59 crew, launching in November.”
NASA did not give provide a reason for the reassignment of Epps, who was selected as an astronaut in 2009.
KENNEDY SPACE CENTER, Fla., August 8, 2017 (CASIS PR)– The SpaceX Falcon 9 vehicle is poised to launch its 12th cargo resupply mission (CRS-12) to the International Space Station (ISS) no earlier than August 13th, 2017 from Kennedy Space Center Launch Pad 39A.
The SpaceX Dragon spacecraft will carry more than 20 ISS National Laboratory payloads to conduct research across a variety of areas aimed at improving life on Earth, including research on Parkinson’s disease, new anti-bacterial compounds, new approaches to treating blood pressure, and pioneering new advances in the use of stem cells for repairing damage from disease, among many others. Thus far in 2017, the ISS National Lab has sponsored more than 100 separate experiments that have reached the station.
HOUSTON (NASA PR) — Vice President Mike Pence will visit NASA’s Johnson Space Center in Houston on Wednesday, June 7, to welcome America’s newest astronaut candidates, chosen from more than 18,000 applicants to carry the torch for future human space exploration.
The event will air live at 2 p.m. EDT on NASA Television and the agency’s website. Additionally, the Vice President will tour the Christopher C. Kraft Jr. Mission Control Center and hear briefings on current human spaceflight operations.
In a lab at NASA’s Johnson Space Center in Houston, engineers simulated conditions that astronauts in space suits would experience when the Orion spacecraft is vibrating during launch atop the agency’s powerful Space Launch System rocket on its way to deep space destinations. A series of tests occurring this month at Johnson will help human factors engineers assess how well the crew can interact with the displays and controls they will use to monitor Orion’s systems and operate the spacecraft when necessary.
Test subjects wore modified advanced crew escape suits that are being developed for astronauts in Orion, and sat in the latest design of the seat atop the crew impact attenuation system. This was the first time this key hardware was brought together to evaluate how launch vibrations may impact the astronaut’s ability to view the displays and controls. While Orion’s late 2018 mission will be uncrewed, engineers are hard at work performing all the necessary evaluations to make sure the spacecraft is ready for crewed missions beginning as early as 2021.
HOUSTON (NASA PR) — As commercial crew astronauts climb inside Boeing’s CST-100 Starliner spacecraft for the first time atop of a United Launch Alliance Atlas V rocket at Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida, there will be something very familiar about what they are doing.
This is because of a new simulator that arrived today at NASA’s Johnson Space Center in Houston, Texas. The Boeing Mission Simulator is a full-scale mock-up of the Starliner outfitted with the same state-of-the-art interior as the real spacecraft. NASA astronauts Eric Boe and Suni Williams worked with the simulator after its assembly in St. Louis before it was shipped to Texas.
HAMPTON, Va. (NASA PR) — A laser-guided navigation sensor that could help future rovers make safe, precise landings on Mars or destinations beyond will soon undergo testing in California’s Mojave Desert.
The Navigation Doppler Lidar, or NDL, which was developed at NASA’s Langley Research Center in Hampton, Virginia, will be flight tested aboard a rocket-powered Vertical Take-off, Vertical Landing (VTVL) platform, named Xodiac, developed by Masten Space Systems, in Mojave, California.
HOUSTON (NASA PR) — Over the summer of 2016, the Next Generation Life Support (NGLS) project received delivery from three industry partners of several new promising spacesuit technologies, namely for advancing glove designs and capabilities. Glove prototypes incorporating these technologies are now undergoing testing and performance evaluation under increased operating pressures and in the more challenging environments expected during future space exploration.
BROOKLYN, NY, October 28, 2016 (FFD PR) – Final Frontier Design (FFD) has delivered a pair of functional Mechanical Counter Pressure (MCP) gloves to NASA’s Johnson Space Center in Houston. This marks a major milestone in FFD’s fixed-price contract with NASA for MCP gloves and represents a promising alternative in space suit pressure garment design.
HOUSTON (NASA PR) — Commercial Crew Program astronauts Bob Behnken and Eric Boe joined flight director Richard Jones and his NASA/Boeing flight control team in the first Mission Control Center, Houston, on-console simulation of Boeing’s CST-100 Starliner launch, climb to orbit and post-orbital insertion timeline.
The ascent simulation included a training team inserting problems remotely from a nearby building, which allowed the team to follow checklists and procedures to solve issues that could arise during a dynamic, real-flight situation.
Boeing has an agreement in place with NASA’s Johnson Space Center to provide flight control and facility expertise in managing missions of the Starliner and United Launch Alliance Atlas V rocket. Simulations covering all aspects of human space flight control have been conducted for every human space flight and prepare the astronauts and flight controllers for the real flights.
Behnken and Boe along with Doug Hurley and Suni Williams are integrated as a group with Boeing and SpaceX on its Dragon crew vehicle through the development phase and first test flights. Specific crew assignments have not yet been announced. Read more about the advances NASA’s Commercial Crew Program have made in 2016: http://go.nasa.gov/24QDPuA
HOUSTON (NASA PR — NASA’s Human Research Program and the German Space Agency (DLR) will fund six proposals to investigate possible changes in the behavioral health and performance of astronauts on future deep space exploration missions. The selected proposals aim to address the impact of the spaceflight environment on various aspects of astronaut health, including cognition, sleep loss and team functioning. This work is helping NASA develop the knowledge and countermeasures necessary to ensure astronauts remain healthy as we venture beyond low-Earth orbit to visit an asteroid and eventually the journey to Mars.

Biologists around the world routinely perform gene expression analysis to better understand living systems. Gene expression analysis examines the types and amounts of molecules produced by genes in living cells, telling us which genes are active and which are inactive at a given point in time. This reveals valuable information about the highly dynamic internal states of cells in living systems. NASA’s WetLab-2 hardware system is bringing to the International Space Station the technology to measure gene expression of biological specimens in space, and to transmit the results to researchers on Earth at the speed of light.

American spacecraft systems testing followed by increasingly complex flight tests and ultimately astronauts flying orbital flights will pave the way to operational missions during the next few years to the International Space Station. Those were the plans laid out Monday by NASA’s Commercial Crew Program officials and partners as they focus on developing safe, reliable and cost-effective spacecraft and systems that will take astronauts to the station from American launch complexes.
Gizmodo has a fascinating story about NASA scientists who appear to have proven that Roger Shawyer’s quantum vacuum plasma thruster, known as the EmDrive (a.k.a., Relativity Drive), actually works. But, they’re not sure exactly why.
Shawyer’s engine is extremely light and simple. It provides a thrust by “bouncing microwaves around in a closed container.” The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be a major breakthrough in space propulsion technology.
Obviously, the entire thing sounded preposterous to everyone. In theory, this thing shouldn’t work at all. So people laughed and laughed and ignored him. Everyone except a team of Chinese scientists. They built one in 2009 and it worked: They were able to produce 720 millinewton, which is reportedly enough to build a satellite thruster. And still, nobody else believed it.
Now, American scientist Guido Fetta and a team at NASA Eagleworks—the advanced propulsion skunkworks led by Dr Harold “Sonny” White at the Johnson Space Center—have published a new paper that demonstrates that a similar engine working on the same principles does indeed produce thrust. Their model, however, produces much less thrust—just 30 to 50 micronewtons. But it works, which is amazing on its own. They haven’t explained why their engine works, but it does work.
TEMPE, Ariz. (NASA PR) — You may not recognize it by name, but if you have ever had a child with a diaper rash, that child was likely a host to Candida albicans (C. albicans). This unwelcome “guest” can be hard to control, as it can potentially lead to serious illness in humans with weakened immune systems. During an investigation dubbed “Microbe,” using the unique microgravity environment aboard space shuttle Atlantis on an International Space Station mission, researchers at the Arizona State University (ASU) in Tempe gained a better understanding of these prevalent fungi. Their tendency to become more aggressive in microgravity helps scientists see what mechanisms control the behavior of these types of organisms, with the potential to develop ways to influence their behavior both in space and on Earth.
PASADENA, Calif. (NASA PR) — What’s more interesting than videos of cats chasing laser beams over the kitchen floor? How about videos sent OVER laser beams from NASA’s International Space Station back to Earth?
A team of about 20 working at NASA’s Jet Propulsion Lab in Pasadena, Calif., through the lab’s Phaeton early-career-hire program, led the development of the Optical Payload for Lasercomm Science (OPALS) investigation, which is preparing for a March 16 launch to the International Space Station aboard the SpaceX-3 mission. The goal? NASA’s first optical communication experiment on the orbital laboratory.
