Надо не психовать по поводу чьих-то там планов, а спокойно допиливать "Ангару" и "Федерацию".

Как раз речь и идёт о том, чтобы не "спокойно допиливать", как это делается сейчас, т.е. ничего не делается - в дальний космос не летаем вообще (ЭкзоМарс - только носитель с разгонным блоком), финансирование всё время урезается в силу абсолютной неэффективной организации космической деятельности с соответствующими результатами, т.е. никакими,, а кардинально изменить организацию и начинать осваивать космос реально, а не виртуально.

Космодром Восточный - строится. Производство "Ангары" - развёртывается (в Омске). Ядерные установки - проектируются. Кое-что делается. А что медленно - если не получается быстрее, пусть хотя бы будет так.

Key Milestone Completed for NASA's Orion Spacecraft to Ensure Astronaut Safety

REDMOND, Wash., March 01, 2017 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), recently completed hot-fire acceptance testing of eight auxiliary engines that will be used on the first flight of NASA's Orion spacecraft with the Space Launch System rocket, slated to launch in 2018.

Orion's European Service Module (ESM), which remains connected to the spacecraft throughout the mission until just prior to Orion's re-entry to Earth's atmosphere, provides propulsion, power, temperature control, air, and water for crew members. The European Space Agency (ESA) is providing the ESM to NASA for Orion. Aerojet Rocketdyne is responsible for the ESM's eight auxiliary engines and is assisting Lockheed Martin in the refurbishment of the Orbital Maneuvering Subsystem (OMS) engine that Aerojet Rocketdyne originally manufactured for the Space Shuttle and will now be used as the main propulsion for ESM.

"The design approach that has power and propulsion provided by a separate service module traces back to the Apollo program," said Aerojet Rocketdyne CEO and President Eileen Drake. "The auxiliary engines we are delivering to Lockheed Martin and NASA for the European Service Module provide a redundant capability to the OMS engine capability."

The ESM auxiliary engines are based on the company's R-4D design and work in concert with the main OMS engine. By performing off-pulsing for steering and providing redundant capability for the main engine, the auxiliary engines are critical to ensuring astronaut safety. Each auxiliary engine provides 105 pounds of thrust and is capable of firing more than 7,000 seconds in space. They will be located in four pairs on the outside of the ESM.

Starting more than 40 years ago with the Apollo program, Aerojet Rocketdyne has built more than 700 R-4D engines that have compiled a record of 100 percent mission success. Variants of the R-4D have played critical roles in orbit-raising maneuvers for commercial satellites, as well as assisting NASA in exploring the solar system aboard spacecraft such as Cassini, which investigated Saturn and its moons.

"Successful acceptance testing of the auxiliary engines brings us one step closer to enabling human exploration well beyond low-Earth orbit," said Mike Hawes, Lockheed Martin Orion vice president and program manager.
In addition to providing propulsion for the ESM, Aerojet Rocketdyne also supplies twelve 160-pound-thrust monopropellant engines for the Orion crew module's reaction control system and the jettison motor that is instrumental in separating the launch abort system from the crew module to keep astronauts safe should a problem arise during launch.

Aerojet Rocketdyne is an innovative company delivering solutions that create value for its customers in the aerospace and defense markets. The company is a world-recognized aerospace and defense leader that provides propulsion and energetics to the space, missile defense and strategic systems, tactical systems and armaments areas, in support of domestic and international markets.

The NASA spacecraft that could one day help ferry humans to Mars is scheduled to undergo a parachute test tomorrow (March 8 ). 
 
The Orion spacecraft can carry humans on long trips into deep space, but once it returns to Earth, it needs a little help touching down. Like the Apollo spacecraft, Orion relies on a parachute system to lower it down through Earth's atmosphere, and safely return astronauts to the ground.
 
The test is scheduled to take place at 7:30 a.m. local time (9:30 a.m. EST/1430 GMT) at the U.S. Army's Yuma Proving Ground in Arizona. A model of Orion will be dropped from a C-17 aircraft flying at an altitude of 25,000 feet, according to a statement from the agency. NASA is currently investigating the possibility of flying two astronauts on a test flight of the Orion spacecraft as early as 2019.

Tomorrow's parachute test will simulate what would happen if an abort sequence took place during Orion's launch. If something goes wrong with NASA's Space Launch Systems (SLS) rocket that Orion is riding on, NASA officials may decide to abort the flight, meaning the spacecraft would be ejected from its seat atop the rocket. In such an event, the parachutes would deploy and drop the spacecraft safely back to Earth. During an abort sequence, the spacecraft will be traveling at the relatively slow speed of about 130 mph [210 km/h], rather than speeds of about 310 mph [500 km/h] during re-entry after reaching space, according to NASA. The drop will last for about four minutes total; the last one to two minutes will take place under fully deployed parachutes, according to a NASA representative.

 
 
 Orion's parachute system consists of 11 parachutes in total: three forward bay cover parachutes (deployed first), two drogue parachutes (deployed second, at about 25,000 feet), and three pilot parachutes (deployed at about 9,500 feet) that subsequently deploy three main parachutes. The parachute system can slow down the space capsule to just 20 mph [32 km/h] before touchdown, according to NASA. During tomorrow's test, the Orion team will focus on "deployment of Orion's two drogue parachutes at low speeds, and deployment of its three main parachutes in preparation for landing."
 
This will be Orion's second airdrop parachute test in a series of eight qualifying drop tests that will replicate various scenarios in which Orion's parachute system would need to be deployed, according to the statement.

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.

NASA's Kennedy Space Center (KSC) and Hensel Phelps Construction Co. successfully completed the modifications to the Vehicle Assembly Building (VAB) in early February, making room for the new Space Launch System (SLS) rocket and the Orion spacecraft.

KSC needed to remove the old space shuttle hardware fr om the VAB in order to make room for the 10 new levels of work platforms. These multi-level work platforms will allow the large portions of the SLS rocket to be integrated and stacked with ease in High Bay 3 (HB3).

During the renovation to HB3, High Bay 2 (HB2) also underwent minor renovations for housing commercial rockets in the future. KSC has completed a major milestone that not only progresses deep space travel but also allows the space center to assert itself as a future spaceport.

As progress continues to be made to accommodate the SLS rocket at KSC, the auxiliary engines for Orion's European Service Module (ESM) completed successful hot-fire testing in February. Aerojet Rocketdyne has been assisting Lockheed Martin in refurbishing the rockets used during the Space Shuttle program.

The eight auxiliary engines, originally the Orbital Maneuvering Subsystem (OMS) engines from the shuttles, are part of Rocketdyne's R-4D design which has compiled a 100 percent mission success record over the years. Rocketdyne is also supplying the 12 monopropellant engines for the Orion crew module and the jettison motor for the launch abort system.

By completing a successful test-fire, the Orion program is one step closer to achieving deep space travel.

Once the Orion capsule is successfully launched aboard the SLS for Exploration Mission-1 (EM-1), Israel's StemRad will be performing product testing as Orion completes a lunar flyby. Developed under CEO Oren Milstein, the AstroRad Radiation Shield is a multi-layered shield for astronauts that accurately cover important organs in the human body.

During EM-1, StemRad will have two "phantom" torso dummies aboard, one wearing the AstroRad Radiation Shield while the other is unprotected. The torso dummies will monitor the radiation absorption experienced during the flyby and will be analyzed once returned to Earth.

StemRad is no stranger to radiation shielding technology, producing a belt that protects workers from harmful gamma ray radiation as a result of nuclear disasters such as Chernobyl and Fukushima.

Since most severe cases of death due to radiation exposure is caused by bone marrow failure, StemRad aimed to find a way to protect bone marrow. By layering protective materials over the pelvis wh ere bone marrow stem cells are located, it allows for damaged bone marrow to be rejuvenated by the shielded stem cells after an exposure.

Before any product tests can be confirmed aboard the Orion capsule for EM-1, NASA needs to re-examine the feasibility of making the Orion capsule a multi-purpose crew vehicle. A NASA authorization bill – passed unanimously by the Senate on February 17 – requires NASA to confirm that the Orion capsule has the capabilities of delivering crew and cargo to the International Space Station (ISS), if other vehicles are unable to execute those functions, along with being a safe deep space crew vehicle.

Following the passing of the authorization bill, NASA proposed submitting a report to assess the feasibility of sending a crew in the Orion capsule for EM-1. A crewed Orion mission was not scheduled to take place until 2021 with Exploration Mission-2 (EM-2).

However, the Trump administration asked NASA to advance the crewed mission to take place on EM-1. This would cause the maiden launch of the Orion capsule aboard the SLS to be postponed until beyond 2019 and require additional funding. The official NASA reports for the multi-purpose crew vehicle re-examination and the crewed EM-1 assessment are due by mid-April and early spring, respectively. Until then, EM-1 remains scheduled to launch, with no crew, in late 2018.  

Lastly, on February 27, the Interim Cryogenic Propulsion Stage (ICPS), which will be used as a second stage on the debut flight of NASA's SLS rocket, was sent by barge to United Launch Alliance's Delta IV Operation Center at Cape Canaveral Air Force Station in Florida.
