ЦитироватьNASA may extend space station missions to address potential commercial crew delays
by Jeff Foust — April 13, 2018

WASHINGTON — NASA is in discussions with its Russian counterparts about extending some upcoming space station missions as a way to buy more time for development of commercial crew vehicles.

During an April 12 hearing by the commerce, justice and science subcommittee of the House Appropriations Committee on the agency's fiscal year 2019 budget proposal, NASA Acting Administrator Robert Lightfoot said longer "increments" of crews on the ISS could be one way to provide more schedule margin in the event of additional delays by Boeing and SpaceX in the development of their crewed spacecraft.
...

Juggling the SLS launch schedule

Lightfoot also said at the hearing that NASA was revisiting the schedule for Space Launch System missions based on the unexpected windfall it received in the final 2018 omnibus appropriations bill.

That bill, signed into law March 23, provided $350 million for NASA to build a second mobile launch platform for the SLS. NASA officials said last year a second platform could help shorten the gap between the first and second SLS launches, but did not include funding for it in its 2019 budget proposal, citing competing priorities.

That second launch platform, which would be designed for the Block 1B version of the SLS with the larger Exploration Upper Stage, would reduce the 33-month "iron bar" in the schedule between the first two SLS missions created by the time needed to modify the current platform. That platform has been built to support the Block 1 version of SLS, which uses the Interim Cryogenic Propulsion Stage (ICPS).

Lightfoot said that having a second launch platform opens the door to launching a second SLS mission with the ICPS. That could be used, he said, to launch the Europa Clipper mission, which could be ready for launch as soon as 2022. NASA's 2019 budget proposal, though, plans a 2025 launch of Europa Clipper using a commercially-procured launch vehicle rather than SLS.

Another option would be to fly the first crewed Orion mission, known as Exploration Mission (EM) 2, on that second SLS Block 1. "If EM-2 flies that way, we would have to change the mission profile because we can't do what we would do if we had the Exploration Upper Stage," he said. "But that still gets humans in orbit and still allows us to check out all the systems that we wouldn't check out on EM-1."

He indicated that the funding for the second mobile launch platform took the agency by surprise. "You're going to have to give us a little time, because that was just a couple weeks ago that we found out that we were getting that," he said.

COLORADO SPRINGS — As Lockheed Martin prepares to complete assembly of the Orion spacecraft flying on the first Space Launch System mission, the company says it's making progress in lowering the costs of the future spacecraft, including through reuse.

In an April 19 interview during the 34th Space Symposium here, Mike Hawes, vice president and Orion program manager at Lockheed Martin Space Systems, said the Orion crew capsule for the Exploration Mission (EM) 1 flight should be ready in June to be combined with the European-built service module, expected to arrive in the U.S. a little later in the summer.
Спойлер
"We're anticipating a delivery date in early July" for the service module, he said. That will be followed by more than a year of integration and testing of the combined spacecraft. "The next year on EM-1, for us, is going to be just chockablock."

The service module has been one of the pacing items in the schedule for the overall mission, along with the SLS core stage. "This is their first-time build, so they have had supplier challenges. They have had some assembly challenges," he said of ESA and the service module prime contractor, Airbus.

Lockheed Martin has provided some technical support, including technicians the company sent to an Airbus factory to assist with service module assembly. "Airbus put us on contract to help their team by sending a few technicians to do cable harness work and some other things," Hawes said. That experience was "very positive" and will help with later in the integrating and testing process.

Elements of the Orion spacecraft that will fly on EM-2, scheduled for launch in the early 2002s, are also in production, he said, including the pressure vessel and heat shield. The company is using experience fr om the EM-1 Orion, as well as the earlier Exploration Flight Test (EFT) 1 Orion mission in 2014, to find ways to lower costs for EM-2 and beyond.

"The places wh ere we had some challenges on EFT-1 we haven't repeated on EM-1," he said. The company has revamped its flow of work on Orion in an operations and checkout built at the Kennedy Space Center, as well as made manufacturing improvements, such as procurement of materials and components from its suppliers.

Lockheed Martin is also finishing a proposal to NASA for future Orion production that will include cost reductions for later, "built-to-print" versions of the spacecraft. "Our goal is 50 percent [cost reduction] on the vehicle, and I think we're going to be close to that," he said.

Hawes said the company expects a "pretty healthy" cost reduction from EM-1 to EM-2 and EM-3, "on the order of 30-plus percent." The rest of the cost reductions will come on later missions, although he didn't give a specific date for achieving that 50 percent goal.

One factor in later cost reductions, he said, will be the reuse of Orion capsule components, including, eventually, the vehicle structure. "We have the internal component reuse that will start even between [EM] 1 and 2, but then when we get to reusing a structure, for instance, that factors in significant savings on a mission basis," he said.

It will be well into the 2020s, though, before part of an Orion spacecraft is reflown. "The baseline that we're looking at with NASA is that the EM-4 structure would refly as the EM-7 structure," he said. That will depend, he said, on experience developed both building and flying spacecraft.

To help in that reuse planning, Hawes said the Orion team at Lockheed Martin is working with other parts of the company, including Lockheed Martin Aeronautics and the Sikorsky helicopter unit, to gain insights on airframe instrumentation and analysis in order to determine the best places to install instrumentation the Orion spacecraft, such as sensors to measure corrosion after exposure to seawater during splashdown and recovery.

Reuse and other manufacturing improvements will also help the company prepare for higher flight rates of Orion spacecraft in the future, with a long-term goal of one mission a year. "When you look at the flow of building a vehicle a year, or conducting a mission a year, it's a pretty imposing schedule, which also tells us we should be starting EM-3 now," he said.

A Window to Space


Inside a laboratory in the Neil Armstrong Operations and Checkout Building at NASA's Kennedy Space Center in Florida, Mark Nurge, Ph.D., at left, a physicist in the Applied Physics Lab with the center's Exploration Research and Technology Programs, and Bence Bartha, Ph.D., a specialist in non-destructive testing with URS Federal Services, are performing the first optical quality testing on a full window stack that is ready for installation in the docking hatch of NASA's Orion spacecraft. The data from the tests will help improve the requirements for manufacturing tolerances on Orion's windows and verify how the window should perform in space.

A few multi-layer windows on a spacecraft provide astronauts the view they may need for navigating space and carrying out their exploration mission with visual data. NASA is working to improve the durability of those windows, and reduce cost and weight, while maintaining the clarity astronauts need to carry out their tasks and view the Earth and other destinations as they travel farther into the solar system.
Спойлер
The space shuttle used only glass panes for its primary windows. While these provided good optical quality, they added costly mass to the spacecraft. Modern spacecraft windows incorporate acrylic and other plastics that are lighter, stronger and less brittle, but often provide lower quality optical properties.

A few years ago, NASA began an effort to ensure the optical quality of the panes used on agency or commercial spacecraft. Each window pane must ensure the view is clear for the astronauts and to help their cameras capture the best possible photographs.

Recently, a team from Kennedy Space Center's Exploration Research and Technology Programs performed the first optical quality testing on a window that is ready for installation in the docking hatch of NASA's Orion spacecraft. On Orion, three panes comprise the hatch window. This hybrid combination of glass and plastics is a first for NASA and will safeguard the spacecraft's inhabitants as one glass pane shields them from the heat of re-entry, another acrylic pane provides protection from the vacuum that surrounds the craft when it is outside of Earth's atmosphere, and the third pane serves as a redundancy for the glass pane.

When you use multiple panes of material for a window, the image you see out of it could be distorted. The tests performed determine the amount of image distortion – the variations in the image seen through an optical material. These are wavefront variations. Think of it as looking at something in water when the surface is moving.

However, according to Kennedy's Mark Nurge, this Orion window shouldn't be a problem. "The window assembly was approximately 10 times better than the stated wavefront requirements," he said.

The data from the tests help improve the requirements for optical quality on Orion's windows and verify how the window should perform in space. The Kennedy team is responsible for testing all the viewing and hatch windows for Orion, and also is working with Commercial Crew Program providers to test windows for their spacecraft headed to the International Space Station.

The primary test measures variations in window pane flatness with an accuracy down to the level of tens of nanometers. The device used in the test can show minute differences between new windows and ones that have been subjected to the simulated pressures of space. The ultimate goal is to determine if there are any distortions outside of the prescribed threshold, so the astronauts onboard the spacecraft can take the most precise images possible.

These window tests are another step towards completion of Orion as the spacecraft is prepared to take humans farther into space than ever before.

Exploration Mission-1 Map



<  Back to Gallery

Exploration Mission-1 (EM-1) will be the first integrated flight test of NASA's deep space exploration system: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida. The first in a series of increasingly complex missions, EM-1 will be an uncrewed flight that will provide a foundation for human deep space exploration, and demonstrate our commitment and capability to extend human existence to the Moon and beyond. During this flight, the uncrewed Orion spacecraft will launch on the most powerful rocket in the world and travel thousands of miles beyond the Moon, farther than any spacecraft built for humans has ever flown, over the course of about a three-week mission.

FUEL TANKS AND WINGS FOR ORION MODULE



23 April 2018
The European service module that will provide power, water, air and electricity to NASA's Orion Moon module has taken a large step closer to completion with the installation of its fuel tanks and testing of its solar wings.

Orion will eventually fly beyond the Moon with astronauts. The first mission – without astronauts – is getting ready for launch in 2019.
Спойлер
The large tanks that will provide propellant for the spacecraft are now fitting snuggly inside the spacecraft at the Airbus assembly hall in Bremen, Germany.


Orion service module fuel tank

The four tanks will each contain about 2000 litres of propellant. In the vacuum of space there is no air to burn so spacecraft fuel tanks include oxidiser and fuel that are mixed to ignite and provide thrust.

The two sets of tanks are connected by intricate pipelines to 33 engines. Sensors and computers control the system.

The European service module is a small but complex spacecraft packed with equipment. The large tanks are installed as one of the last components to allow technicians more room to work.

ESA's propulsion lead for Orion, Thierry Kachler, says: "Tank installation is a great achievement and a big step towards the start of the final acceptance tests in Europe."

Shaking the solar wings


Orion solar wing testing

Meanwhile the solar arrays Orion will use to produce electricity are being tested at ESA's technical heart in the Netherlands. Folded for launch, the fragile solar panels need to survive the rumbling into space aboard the most powerful rocket ever built, NASA's Space Launch System.

Orion's solar panels will be folded inside the rocket fairing on the first leg of the trip around the Moon. Once released from the rocket they will unfold and rotate towards the Sun to start delivering power.

To make sure the solar panels will work after the intense launch, ESA engineers are putting them through rigorous tests that exceed what they will experience on launch day. This includes vibrating them on a shaking table and placing them in front of enormous speakers that recreate the harsh launch conditions.

Once they pass these tests they can be sent to Bremen to join the service module.

The service module is set to ship to the USA this summer for further tests and integration with the crew module adaptor.
