NASA's Orion Spacecraft Parachutes Tested at U.S. Army Yuma Proving Ground (News Release)
Engineers successfully tested the parachutes for NASA's Orion spacecraft at the U.S. Army Yuma Proving Ground in Arizona Wednesday, March 8. This was the second test in a series of eight that will certify Orion's parachutes for human spaceflight.
The test, which dropped an Orion engineering model from a C-17 aircraft at 25,000 feet, simulated the descent astronauts might experience if they have to abort a mission after liftoff.
Orion, which will launch atop NASA's Space Launch System rocket from the agency's Kennedy Space Center in Florida, is built to take astronauts farther into the solar system than ever before. The spacecraft will carry crew to space, provide emergency abort capabilities, sustain the crew during their mission and provide safe re-entry through Earth's atmosphere.

Flight Hardware for NASA's Space Launch System on Its Way to Cape (News Release)
The interim cryogenic propulsion stage (ICPS) for the first flight of NASA's Space Launch System rocket is on its way by barge to United Launch Alliance's Delta IV Operation Center at Cape Canaveral Air Force Station in Florida. The ICPS is a liquid oxygen/liquid hydrogen-based system that will provide the thrust needed to send the Orion spacecraft and 13 secondary payloads beyond the moon before Orion returns to Earth. It will be the first integrated piece of SLS hardware to arrive at the Cape and undergo final processing and testing before being moved to Ground Systems Development Operations at NASA's Kennedy Space Center.
The ICPS was designed and built by ULA in Decatur, Alabama, and The Boeing Co. in Huntsville, Alabama. When completed, SLS will be the most powerful rocket in the world for deep-space missions.

Propelling Orion (News Release)
Even the most complex of systems comes down to properly configured wires and cables, such as those pictured here on the Propulsion Qualification Model of the Orion service module.
ESA’s contribution to NASA’s Orion spacecraft is the European Service Module, designed to provide the spacecraft’s propulsion, electrical power, water and thermal control. The model, designed by Airbus Defence and Space, was assembled by OHB Sweden.
Made from steel and containing propellant and helium tanks, among various electronics and command systems, the Propulsion Qualification Model allows engineers to determine how well systems are working together.
The model was built in January in Stockholm, Sweden and has since been shipped to the White Sands Test Facility in New Mexico (USA), where it will undergo more extensive testing by NASA, ESA and main contractor Airbus DS.

SpaceX's Falcon 9 Rocket Finally Lifts Off from Historic Apollo and Space Shuttle Launch Pad in Florida...
NASA Cargo Headed to Space Station Includes Important Experiments, Equipment (Press Release)
Major experiments that will look into a range of scientific disciplines from human health to atmospheric conditions on Earth are on their way to the International Space Station following liftoff at 9:39 a.m. EST aboard a SpaceX Falcon 9 rocket. About 5,500 pounds of research equipment, cargo and supplies are packed into the SpaceX Dragon spacecraft that is now in Earth orbit and headed to the station on the CRS-10 mission.
SpaceX’s Dragon cargo craft launched from Launch Complex 39A at NASA's Kennedy Space Center in Florida. This was the first commercial launch from Kennedy’s historic pad.
Astronauts Thomas Pesquet of ESA (European Space Agency) and Shane Kimbrough of NASA will use the space station’s robotic arm to capture Dragon when it arrives at the station. Live coverage of the rendezvous and capture will begin at 4:30 a.m. Wednesday, Feb. 22 on NASA TV and the agency’s website, with installation coverage set to begin at 8:30 a.m.
Research materials flying inside the Dragon's pressurized area include a crystal growth experiment that will crystallize a monoclonal antibody that is undergoing clinical trials for the treatment of immunological diseases. Growing the crystal in space will allow it develop more than it could on Earth where gravity causes crystals to collapse on themselves. Preserving these antibodies in crystals allows researchers a glimpse into how the biological molecules are arranged, which can provide new information about how they work in the body. So far, Earth-grown crystalline suspensions of monoclonal antibodies have proven to be too low-quality to fully model.
Better defining how some bacteria become drug-resistant is the focus of another experiment that aims to develop medicines that counter the resistance. Stem cells like those used to treat strokes and other occurrences also will be studied using experiment supplies brought up on this flight.
The equipment aboard the Dragon includes a major instrument that will survey Earth's upper atmosphere in a continuation of one of NASA's longest-running Earth-observing programs. Called SAGE III for Stratospheric Aerosol and Gas Experiment, the instrument examines the levels of ozone, aerosols, nitrogen dioxide and water vapor in the stratosphere and troposphere high above Earth. It is the latest version of an experiment that began in 1979 and has created a multi-decade record of measurements. The 2,200-pound instrument will be connected to the outside of the station to make daily observations for several years.
The mission is the company's tenth cargo flight to the station under NASA’s Commercial Resupply Services contract. Dragon's cargo will support dozens of the more than 250 science and research investigations during the station’s Expeditions 50 and 51.
Dragon is scheduled to depart the space station in late March, returning nearly 5,000 pounds of science, hardware and crew supplies.
For more than 16 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 200 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 1,900 research investigations from researchers in more than 95 countries.

Just thought I'd share this pic that SpaceX released today showing its Falcon 9 vehicle—with the Dragon cargo freighter now installed atop the rocket—poised for launch atop Pad 39A at NASA's Kennedy Space Center in Florida. The Falcon 9 is set to lift off towards the International Space Station at 10:01 AM, Eastern Standard Time (7:01 AM, Pacific Standard Time) tomorrow...assuming that engineers will be able to rectify an upper stage issue as mentioned in Elon Musk's tweet below. Cross your fingers.
Investigating a (very small) leak in the upper stage. If ok, will launch tomorrow. https://t.co/bQf97lywn4— Elon Musk (@elonmusk) February 17, 2017

SpaceX Update: A Rocket Will Launch from Kennedy Space Center's LC-39A for the First Time in Almost Six Years...
While repairs continue to take place at its main launch site at Florida's Cape Canaveral Air Force Station (CCAFS) following a pad explosion in September of last year (see video below), SpaceX is ready to launch a Falcon 9 rocket from nearby Kennedy Space Center (KSC) less than three weeks from today. Set for tomorrow is a static fire test of the Falcon 9's Merlin 1D engines at KSC's Launch Complex (LC)-39A...which last saw a rocket lift off from its perimeter in July of 2011. It was on July 8 of that year that Atlantis lifted off from this pad to begin mission STS-135, the final flight of the space shuttle program.
Assuming that everything goes well during the static fire tomorrow morning, the Falcon 9 will launch on February 18 to send a Dragon cargo freighter to the International Space Station. LC-39A will be the East Coast launch site for Falcon 9 rockets until Space Launch Complex 40 at CCAFS is back in operation. Along with the Falcon 9, LC-39A will also be the permanent site where SpaceX's Falcon Heavy vehicle lifts off from terra firma to venture beyond Earth's atmosphere...its maiden flight set for later this year. Stay tuned!

Final Work Platform Installed in Vehicle Assembly Building for NASA's Space Launch System (News Release)
NASA reached a key milestone in the Vehicle Assembly Building (VAB) at the agency's Kennedy Space Center in Florida. A year of platform installations came to conclusion in January as the final work platform, A north, was lifted, installed and secured recently on its rail beam on the north wall of High Bay 3 inside the iconic facility.
The installation of the final topmost level completes the 10 levels of work platforms, 20 platforms halves altogether, that will surround NASA's Space Launch System (SLS) rocket and the Orion spacecraft and allow access during processing for missions, including the first uncrewed flight test of Orion atop the SLS rocket.
"Just a year ago, we were meeting the challenges of getting the first half of the first platform installed," said Mike Bolger, Ground Systems Development and Operations (GSDO) Program manager, "It's a great testament to the creativity, persistence and hard work of the team, and it's a terrific indicator that GSDO is on track to process the SLS and Orion flight hardware for the first test mission."
The A platforms will provide access to the Orion spacecraft's Launch Abort System (LAS) for Orion lifting sling removal and installation of the closeout panels. LAS Antenna Testing also is performed on this level.
The platforms were mated with two, 60,000-pound rail beam assemblies that allow the platforms to move towards and away from the vehicle, as well as tie the entire system to the VAB structure. Each platform will ride on four Hillman roller systems on each side — much like how a kitchen drawer glides in and out. The process to lift and install each of the platforms takes about four hours. Each platform weighs more than 300,000 pounds, and measures about 38 feet long and close to 62 feet wide.
"I am very proud of the amount of work that the team accomplished. I am also humbled to have been able to lead this group of amazing people who have been able to complete this very complex and challenging project," said Jose Perez Morales, GSDO VAB Element senior project manager. "I am very pleased with all the work performed by the NASA and contractor team."
Engineers began installation of the first halves, the K-level platforms, about a year ago, followed by the J, H and G platforms. In July 2016, platform installation reached the halfway point, with the fifth of ten levels of platforms, the F-level, completed.
The remaining platforms installed are E, D, C, B and A. Each of the platform levels is strategically located to allow technicians and engineer’s access to different systems on the rocket, Orion spacecraft and the Launch Abort System during processing and stacking operations on the mobile launcher.
"This is a huge day for us," said Darrell Foster, GSDO Project Management Division chief. "We cherish these milestones. We're all working toward launch day success."
GSDO, with support from the center's Engineering Directorate, is overseeing upgrades to the VAB, including the installation of the work platforms.
NASA awarded a contract to modify High Bay 3 to the Hensel Phelps Construction Co. of Greeley, Colorado, in March 2014. Hensel Phelps, along with its subcontractors, Institutional Services Contract, Engineering Services Contract, and Test and Operation Support Contractor, supported crane operations, lifting, installation and initial inspection of each of the platforms.

Major Review Completed for NASA’s New SLS Exploration Upper Stage (News Release - January 27)
NASA has successfully completed the exploration upper stage (EUS) preliminary design review for the powerful Space Launch System rocket. The detailed assessment is a big step forward in being ready for more capable human and robotic missions to deep space, including the first crewed flight of SLS and NASA's Orion spacecraft in 2021.
"To send humans and even more cargo farther away from Earth than ever before, NASA decided to add a more powerful upper stage -- the upper part of the rocket that continues to operate after launch and ascent," said Kent Chojnacki, EUS team lead and preliminary design review manager.
"With the completion of this review, our teams will start developing components and materials for the EUS, and build up tooling," he added. "Full-scale manufacturing will begin after the critical design phase is completed." Critical design review is the next programmatic milestone that will provide a final look at the design and development of the EUS before beginning full-scale fabrication.
Starting with that first crewed mission, future configurations of SLS will include the larger exploration upper stage and use four RL10C-3 engines. The EUS will replace the interim cryogenic propulsion stage that will be used on the initial configuration of SLS for the first, uncrewed flight with Orion. The EUS will use an 8.4-meter diameter liquid hydrogen tank and a 5.5-meter diameter liquid oxygen tank. A new universal stage adapter will connect the EUS to the Orion spacecraft, and be capable of carrying large co-manifested payloads, such as a habitat.
The preliminary design review kicked off Nov. 30, 2016, with approximately 500 experts from across NASA and industry assessing more than 320 items on the EUS, including documents and data. This review had a new "techie" touch to it with the incorporation of virtual reality glasses, which gave teams enhanced visuals of how the EUS is put together and a broader perspective on the size of the hardware. The preliminary design review board was completed Jan. 19, with the board voting unanimously that the EUS is ready to move to the critical design phase.
"I couldn’t be prouder of the SLS Stages team completing this review," said SLS Program Manager John Honeycutt. "We continue to make progress on hardware for SLS’s first flight, while also working on the next-generation rocket that will take astronauts to deep-space destinations, like Mars."
The powerful stage will be built at NASA's Michoud Assembly Facility in New Orleans. Massive welding machines, like the Vertical Assembly Center, currently building the SLS core stage, also will help build the EUS liquid hydrogen tank. New tooling and assembly areas will be put in place to manufacture the liquid oxygen tank.
Once built, the EUS structural test article will undergo qualification testing at NASA's Marshall Space Flight Center in Huntsville, Alabama, to ensure the hardware can withstand the incredible stresses of launch. "Green run" testing on the first flight article will be done at NASA's Stennis Space Center near Bay St. Louis, Mississippi. For the test, the EUS and RL10 engines will fire up together for the first time before being sent to Kennedy Space Center in Florida for the 2021 launch.
