Booster Segment Answers 'Casting' Call for First Flight of SLS (Press Release)

The first of 10 flight segments for the two solid-rocket boosters of NASA’s Space Launch System has been cast at Orbital ATK’s facility in Promontory, Utah. Casting involves filling the insulated metal case with propellant and allowing it to solidify or “cure” for several days. The hardware, which is the aft segment, will eventually be integrated with four other segments to make up one of the two, five-segment solid rocket boosters for the first flight of SLS in 2018. During this flight, called Exploration Mission-1, SLS will carry an unmanned Orion spacecraft to travel thousands of miles beyond the moon over the course of about a three-week mission and help NASA prepare for missions to deep space, including Mars. Orbital ATK is the prime contractor for the boosters.

Welding Wonder Completes Hardware for First Flight of NASA's SLS Rocket (Press Release)

Flight hardware for the core stage of the world's most powerful rocket, NASA's Space Launch System, finishes final welding and is moved off the 170-foot-tall Vertical Assembly Center at the agency's Michoud Assembly Facility in New Orleans. The hardware is for the engine section, and is the first major SLS flight component to finish full welding on the Vertical Assembly Center. The engine section is located at the bottom of the rocket's core stage and will house the four RS-25 engines for the first flight of SLS with NASA's Orion spacecraft in 2018.

The SLS core stage will stand at more than 200 feet tall and store cryogenic liquid hydrogen and liquid oxygen that will feed the launch vehicle’s RS-25 engines. A qualification version of the engine section, which also has completed welding on the Vertical Assembly Center at Michoud, will be shipped later this year to NASA's Marshall Space Flight Center in Huntsville, Alabama, to undergo structural loads testing on a 50-foot test structure currently under construction.

All welding for the core stage of the SLS Block I configuration -- including confidence, qualification and flight hardware -- will be completed this summer. Traveling to deep space requires a large vehicle that can carry huge payloads, and SLS will have the payload capacity needed to carry crew and cargo for those exploration missions, including Mars.

ISS Update: The BEAM Has Been Installed!

Earlier today, astronauts aboard the International Space Station (ISS) successfully attached the Bigelow Expandable Activity Module (BEAM) to the orbital outpost. The inflatable prototype was launched to the ISS via SpaceX's Falcon 9 booster and the Dragon capsule eight days ago...and will be fully inflated next month. BEAM will remain at the outpost for two years before being detached from the space station to re-enter Earth's atmosphere, where it will burn up during re-entry.

The Bigelow Expandable Activity Module is about to be attached to the International Space Station...on April 16, 2016.

April 14, 1981, Landing of First Space Shuttle Mission (Press Release)

On April 14, 1981, the rear wheels of the space shuttle orbiter Columbia touched down on Rogers dry lake at Edwards Air Force Base, NASA's Armstrong Flight Research Center (then Dryden Flight Research Center), in southern California, to successfully complete a stay in space of more than two days. Astronauts John W. Young, STS-1 commander, and Robert L. Crippen, pilot, were aboard the vehicle. The mission marked the first NASA flight to end with a wheeled landing and represented the beginning of a new age of spaceflight that would employ the same hardware repeatedly.

An area of the air base was set aside for public viewing of the landing, and crowds numbered well over 200,000 people, with some estimates as high as 300,000 visitors who flocked to the site. Media from around the world added to the throng, as radio and TV trucks of all shapes and sizes rolled in from everywhere.

James Young, Chief Historian of the Air Force Flight Test Center at Edwards AFB, remembered the landing well. "You just had to be there to hear, even feel, the double crack of the sonic boom," Young said. "It was such a tremendous sense of excitement to see something never seen before, to witness such a historic event."

Photo of the Day: Welcome Back, Falcon 9!

Last night, the droneship carrying the Falcon 9 rocket that successfully launched Dragon on the CRS-8 mission to the International Space Station last Friday finally arrived at Port Canaveral in Florida. From there, the booster will be transported to Launch Complex 39A (which is now leased by SpaceX) at NASA's Kennedy Space Center to undergo at least 10 test firings. If those tests are successful, then this booster will possibly be reused for another orbital launch several months from now. SpaceX is making history!

NASA Cargo Headed to Space Station Includes Habitat Prototype, Medical Research (Press Release)

Tucked in the trunk of the latest commercial cargo spacecraft to head for the International Space Station is an expandable structure that has the potential to revolutionize work and life on the space station.

SpaceX's Dragon spacecraft is delivering almost 7,000 pounds of cargo, including the Bigelow Expandable Activity Module (BEAM), to the orbital laboratory following its launch on a Falcon 9 rocket at 4:43 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The mission is SpaceX’s eighth cargo delivery through NASA’s Commercial Resupply Services contract. Dragon's cargo will support dozens of the more than 250 science and research investigations taking place on the space station during Expeditions 47 and 48.

“The cargo will allow investigators to use microgravity conditions to test the viability of expandable space habitats, assess the impact of antibodies on muscle wasting, use protein crystal growth to aid the design of new disease-fighting drugs and investigate how microbes could affect the health of the crew and their equipment over a long duration mission,” said NASA Deputy Administrator Dava Newman.

Dragon will be grappled at 7 a.m. Sunday, April 10, by ESA (European Space Agency) astronaut Tim Peake, using the station's Candarm2 robotic arm, with help from NASA astronaut Jeff Williams.

BEAM will arrive in Dragon’s unpressurized trunk and, after about five days, will be removed and attached to the station. Expansion is targeted for the end of May. The module will expand to roughly 10 feet in diameter and 13 feet long. During its two-year test mission, astronauts will enter the module for a few hours several times a year to retrieve sensor data and assess conditions. Expandable habitats are designed to take up less room on a rocket, but provide greater volume for living and working in space once expanded. This first in situ test of the module will allow investigators to gauge how well the habitat protects against solar radiation, space debris and contamination.

Crew members experience significant decreases in bone density and muscle mass during long-duration spaceflight without appropriate nutrition and exercise. One life science investigation on its way to the orbiting laboratory will assess myostatin inhibition as a means of preventing skeletal muscle atrophy and weakness in mice exposed to long-duration spaceflight. Drugs tested on the space station could progress to human clinical trials back on Earth to validate their effectiveness for future space missions.

Dragon also will deliver Microchannel Diffusion, a study of fluids at the nanoscale, or atomic, level. Nanofluidic sensors could measure the air in the space station, or be used to deliver drugs to specific places in the body. The laws that govern flow through nanoscale channels are not well understood, and this investigation simulates those interactions by studying them at the larger microscopic level. This type of research is possible only on the space station, where Earth’s gravity is not strong enough to interact with the molecules in a sample, so they behave more like they would at the nanoscale. Knowledge gleaned from the investigation may have implications for drug delivery and particle filtration, as well as future technological applications for space exploration.

Another experiment onboard Dragon is a protein crystal growth investigation focused on drug design and development. Growing protein crystals in microgravity can help researchers avoid some of the obstacles inherent to protein crystallization on Earth, such as sedimentation. One investigation will study the effect of microgravity on the co-crystallization of a membrane protein to determine its three-dimensional structure. This will enable scientists to chemically target and inhibit, with “designer” compounds, an important human biological pathway thought to be responsible for several types of cancer.

The spacecraft is scheduled to depart the space station May 11 for a splashdown in the Pacific Ocean, west of Baja California, bringing almost 3,500 pounds of science, hardware and spacewalking tools back to Earth for further study, including biological samples from NASA’s one-year mission.

The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has been continuously occupied since November 2000. In that time, it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.

25 Years Ago Today: A Great Observatory Is Deployed In Space...

NASA's Compton Gamma Ray Observatory is deployed from space shuttle Atlantis...on April 7, 1991.
NASA

April 7, 1991, Deployment of Breakthrough Gamma-ray Observatory (Press Release)

Twenty-five years ago, NASA launched the Compton Gamma Ray Observatory, an astronomical satellite that transformed our knowledge of the high-energy sky. Over its nine-year lifetime, Compton produced the first-ever all-sky survey in gamma rays, the most energetic and penetrating form of light, discovered hundreds of new sources and unveiled a universe that was unexpectedly dynamic and diverse.

In this view, taken on April 7, 1991, from the aft flight deck window of space shuttle Atlantis, the Compton Gamma Ray Observatory is released by the shuttle's remote manipulator system. Visible on the observatory as it drifts away are the four complement instruments: the Energetic Gamma Ray Experiment (bottom); Imaging Compton Telescope (COMPTEL) (center); Oriented Scintillation Spectrometer Experiment (OSSE) (top); and Burst and Transient Source Experiment (BATSE) (at four corners).

NASA Progresses Toward SpaceX Resupply Mission to Space Station (Press Release)

NASA provider SpaceX is scheduled to launch its eighth Commercial Resupply Services mission to the International Space Station on Friday, April 8. NASA Television coverage of the launch begins at 3:30 p.m. EDT.

The SpaceX Dragon spacecraft is targeted to lift off on the company's Falcon 9 rocket at 4:43 p.m. from Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida, carrying science research, crew supplies and hardware to the orbiting laboratory in support of the Expedition 47 and 48 crews.

NASA TV also will air two briefings on Thursday, April 7. At 1 p.m., scientists and researchers will discuss some of the investigations to be delivered to the station, followed by a briefing by mission managers at 3:30 p.m. The briefings also will stream live on the agency’s website.

About 10 minutes after launch, Dragon will reach its preliminary orbit, deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.

The spacecraft will arrive at the station Sunday, April 10, at which time NASA astronaut Jeff Williams and ESA (European Space Agency) astronaut Tim Peake will use the station’s robotic arm to capture the Dragon spacecraft. Ground commands will be sent from Houston to the station’s arm to install Dragon on the bottom side of the Harmony module for its stay at the space station. Live coverage of the rendezvous and capture will begin at 5:30 a.m. on NASA TV, with installation set to begin at 9:30 a.m.

The following day, the crew will pressurize the space between the station and Dragon and open the hatch between the two spacecraft.

The Dragon spacecraft will deliver almost 7,000 pounds of supplies and vehicle hardware to the orbital outpost and its crew. The cargo includes the Bigelow Expandable Activity Module (BEAM), which will be attached to the space station to test the use of an expandable space habitat in microgravity. Scheduled to return to Earth in May, the Dragon spacecraft will bring back biological samples from astronauts, including those collected during NASA’s one-year mission.

The new experiments arriving to the station will help investigators study muscle atrophy and bone loss in space, use microgravity to seek insight into the interactions of particle flows at the nanoscale level and use protein crystal growth in microgravity to help in the design of new drugs to fight disease.

Dragon is scheduled to return to Earth on May 11. About five-and-a-half hours after it leaves the station, it will splash down in the Pacific Ocean off the coast of Baja California.

Media at the agency’s Kennedy Space Center in Florida will have the opportunity to participate in special tours and briefings on April 7 and 8, as well as view the launch. The deadline for media to apply for accreditation for this launch has passed. For more information about media accreditation, contact Jennifer Horner at 321-867-6598 or jennifer.p.horner@nasa.gov.

If the launch does not occur on Friday, April 8, the next launch opportunity is 4:20 p.m. Saturday, April 9, with NASA TV coverage starting at 3:15 p.m.
