Editor’s note: NASA issued the following statement updating this article on March 15, 2018:
Mark and Scott Kelly are still identical twins; Scott’s DNA did not fundamentally change. What researchers did observe are changes in gene expression, which is how your body reacts to your environment. This likely is within the range for humans under stress, such as mountain climbing or SCUBA diving.
Nearly three years after a SpaceX Falcon 9 failed in flight sending a Dragon resupply ship to the bottom of the Atlantic, NASA has finally released a public summary of its own investigation into the accident. [Public Summary — PDF]
You might recall that SpaceX’s internal accident investigation blamed a defective strut assembly in the second stage liquid oxygen (LOX) tank. The strut, provided by an outside supplier, snapped under launch stresses, causing a helium bottle inside the tank to break free and destroy the LOX tank, the company said.
The NASA investigation found that is a credible scenario for the accident. However, the space agency blamed a “design error” by SpaceX. The table below shows a summary of the investigation’s technical findings.
NASA has selected four advanced manufacturing projects for funding under the space agency’s Small Business Innovation Research (SBIR) Phase II program.
Ultratech Machinery, Made in Space, Supercool Metals and Intelligent Optical Systems were selected for two-year contracts worth up to $750,000 apiece. Each company received funding for its project under the first phase of the SBIR program.
Ultratech Machinery is being funded to develop a multi-material, ultrasonic additive manufacturing (3D printing) laboratory for use aboard the International Space Station (ISS).
NASA has selected two proposals from Made in Space focused on producing advanced crystals and high-strength components for funding under the space agency’s Small Business Innovation Research program. Each two-year Phase II is worth up to $750,000.
The Industrial Crystallization Facility (ICF) would produce “nonlinear optical single crystals and other relatively large material formulations, such as bulk single-crystal thin films and high temperature optical fiber,” according to the proposal.
It was a successful week for launches around the world.
On Tuesday, SpaceX conducted its 50th launch of the Falcon 9 rocket. The booster orbited the 30W-6 communications satellite for Hispsat of Spain from Cape Canaveral Air Force Base in Florida. At 6 metric tons, it was the heaviest geosynchronous satellite ever launched by SpaceX.
On Friday, a Soyuz booster roared off the pad in French Guiana to deliver four O3b F4 communications satellites for SES. It was the third successful launch of Russia’s workhorse Soyuz rocket this year.
NASA has selected a proposal from Techshot to develop a variable gravity rodent centrifuge for funding under the space agency’s Small Business Innovation Research (SBIR) program. The two-year Phase II contract is worth up to $750,000.
“The counter-balanced centrifuge is designed to provide a facility to allow rats and mice to live and be observed in simulated gravity between 0-1 g for up to 90 days,” the company said in its proposal. “This streamlined design is more cost efficient and provides up to five cages. Each cage can accommodate at least six 30 gram mice, three 200 gram rats, or two 400 gram rats per cage.”
In recent weeks, Chinese officials have revealed more details about the investigation into the Long March 5 launch failure last year as well as their ambitious launch plans for this year, which include a landing on the far side of the moon.
Long March 5 will be returned to flight in the second half of 2018, according to Bao Weimin, head of the Science and Technology Committee of the China Aerospace Science and Technology Corporation (CASC). Engineers have identified the cause of a launch failure that occurred last July and are working to verify it, he said.
HOUSTON (NASA PR) — In December 2015, Gabe MacPhail, a seventh grader at St. Thomas More Cathedral School in Arlington, Virginia, travelled to Florida along with 100 other members of the school’s community to watch as the fourth Orbital-ATK Cygnus Commercial Resupply Service lifted into orbit atop an Atlas V rocket aimed toward the International Space Station.
NASA would launch the first element of a human-tended Lunar Orbital Platform-Gateway in 2022 under a proposed exploration plan that would make use of commercial and international partnerships.
A power and propulsion module would be followed soon afterward by habitation, airlock, and logistics modules. The gateway would serve as a base for astronauts to explore the moon for the first time since Apollo 17 lifted off from the surface in 1972.
Endurance: A Year in Space, A Lifetime of Discovery by Scott Kelly with Margaret Lazarus Dean Alfred A. Knoff 2017 369 pages
Scott Kelly was failing out of college when he spotted a book at the campus store that would utterly change his life: The Right Stuff, Tom Wolfe’s classic tale of Cold War-era test pilots and the Mercury astronauts.
As he read Wolfe’s prose, Kelly realized that flying jets had the same type of adrenaline rush he felt working as an EMT, which had been the only thing he had excelled at thus far. He decided he would pursue a career as an U.S. Navy aviator.
Decades later, he would call Wolfe in the midst of a year-long stay aboard the International Space Station (ISS) to thank him and ask for advice about how to write a book of his own.
Endurance is the result. The memoir doesn’t live up to Wolfe’s stylistic brilliance, but what the book lacks in style it more than makes up for in inspiration. (more…)
WASHINGTON (NASA PR) — In order to maximize investment in, and benefits of, future deep space exploration platforms and technologies, NASA and its International Space Station partners have collaborated to draft standards that address seven priority areas in which technology compatibility is crucial for global cooperation.
Friedrichshafen/Bremen, Germany (Airbus PR) – Airbus, in cooperation with IBM, is developing CIMON (Crew Interactive MObile CompanioN), an AI-based assistant for astronauts for the DLR Space Administration. The technology demonstrator, which is the size of a medicine ball and weighs around 5 kg, will be tested on the ISS by Alexander Gerst during the European Space Agency’s Horizons mission between June and October 2018.
Below is the current launch schedule for March. In total, there are 8 launches planned for the month with 16 communications satellites, one meteorological satellite, and one crew mission to the International Space Station. The launches include:
WASHINGTON (NASA PR) — NASA has selected 11 small research satellites from seven states and Puerto Rico to fly as auxiliary payloads aboard space missions planned to launch in 2019, 2020, and 2021.
The selections are part of the ninth round of the NASA CubeSat Launch Initiative. CubeSats are a type of spacecraft called nanosatellites, often measuring about four inches on each side and weighing less than three pounds, with a volume of about one quart. CubeSats are built using these standard dimensions as Units or “U”, and are classified as 1U, 2U, 3U, or 6U in total size.
Senators express concerns over proposed cuts to the International Space Station in letters to Director Mulvaney, Acting NASA Administrator Lightfoot
WASHINGTON, D.C. (Sens. Ted Cruz & Bill Nelson PR) – Last week, U.S. Sens. Ted Cruz (R-Texas) and Bill Nelson (D-Fla.), the chairman of the Subcommittee on Space, Science and Competiveness, and the ranking member of the Committee on Commerce, Science, and Transportation, sent the following oversight letters to Office of Management and Budget Director Mick Mulvaney and Acting NASA Administrator Robert Lightfoot Jr. In the letters, the Senators expressed their concerns with the President’s FY 2019 Budget Request for NASA, which proposes ending direct U.S. Government funding for the International Space Station (ISS) by 2025.
