Hola amigos: A VUELO DE UN QUINDE EL BLOG., La misión de la NASA para enviar astronautas a destinos del espacio profundo, donde ningún otro ser humano ha viajado ha dado otro importante paso adelante con la realización de un hito fundamental para la nave espacial Orion actualmente en producción.
Funcionarios de la agencia han completado una revisión técnica y programática rigurosa, lo que confirma el apoyo continuo del programa y establecer el compromiso de la NASA de técnica, el costo, y el horario de referencia del programa. Esta es la primera vez que la NASA ha alcanzado este nivel de progreso para una nave espacial diseñada para tomar los humanos en el espacio profundo más allá de la luna, incluyendo a un asteroide en órbita lunar y en el viaje a Marte.

NASA’s mission to send astronauts to deep space destinations where no
other human has traveled has taken another important step forward with
the completion of a critical milestone for the Orion spacecraft
currently in production.
Agency officials have completed a rigorous technical and programmatic
review, confirming continued support of the program and establishing
NASA’s commitment to the program’s technical, cost, and schedule
baseline. This is the first time NASA has reached this level of progress
for a spacecraft designed to take humans into deep space beyond the
moon, including to an asteroid placed in lunar orbit and on the journey
to Mars.
“Our work to send humans out into the solar system is progressing,”
said NASA Administrator Charles Bolden. “Orion is a key piece of the
flexible architecture that will enable humanity to set foot on the Red
Planet, and we are committed to building the spacecraft and other
elements necessary to make this a reality.”
A successful test of an uncrewed Orion capsule, Exploration Flight
Test-1 (EFT-1), flew in December 2014, providing important data that
allowed engineers to identify risks associated with deep space flight
and re-entry and use that knowledge to improve the design of Orion for
its next test flights, Exploration Missions 1 and 2 (EM-1 and EM-2).
Performance data has helped to improve manufacturing processes, as
well. Engineers have already incorporated many of these improvements
into elements of the EM-1 design, including the crew compartment or
pressure vessel, which now is in fabrication and assembly at companies
across the country. The vessel is comprised of seven panels or sections,
and the first two of these were welded together
last week. When complete, this capsule will launch on NASA’s Space
Launch System (SLS) rocket on the first fully integrated flight test,
EM-1.
Astronauts will fly on Orion for the first time on EM-2. That mission
will build on the results of the EM-1 flight with additional
requirements that the Orion capsule includes fully integrated
environmental control and life support systems; controls; and
communications designed specifically for the human operation; and
advanced launch and re-entry spacesuits for the crew. The recent review,
culminating in what is known within NASA as Key Decision Point C
(KDP-C), includes all of these technological advancements, and approval
represents agency support for this work and the Orion program plan.
The decision commits NASA to a development cost baseline of $6.77
billion from October 2015 through the first crewed mission (EM-2) and a
commitment to be ready for a launch with astronauts no later than April
2023. The commitment is consistent with funding levels in the
president’s budget request. Conservative cost and schedule commitments
outlined in the KDP-C align the Orion Program with program management
best practices that account for potential technical risks and budgetary
uncertainty beyond the program's control.
“As we take these steps to develop the capabilities we need to send
astronauts deep into space, we’re also aligning how we manage our human
exploration systems development programs to ensure we are prepared for
unforeseen future hurdles,” said Robert Lightfoot, NASA associate
administrator. “We’re committing to this funding and readiness level to
stay on the journey we’ve outlined to get to Mars.”
Orion engineers now are executing a rigorous review
of the spacecraft’s engineering design and technical progress of the
vehicle systems and subsystems. This critical design review (CDR) will
demonstrate Orion is ready to proceed to full-scale fabrication,
assembly, integration and testing. NASA’s SLS Program recently completed this milestone, and its Ground Systems Development and Operations (GSDO) Program will begin its review this fall.
“The Orion Program has done incredible work, progressing every day
and meeting milestones to prepare for our next missions,” said William
Gerstenmaier, the agency’s associate administrator for Human Exploration
and Operations at NASA Headquarters. “The team will keep working toward
an earlier readiness date for a first crewed flight, but will be ready
no later than April 2023, and we will keep the spacecraft, rocket and
ground systems moving at their own best possible paces.”
In the coming months, Orion will complete its CDR; see the arrival of
a test version for the European Space Agency-provided service module at
NASA’s Plum Brook Station near Sandusky, Ohio; perform a series of
parachute tests; and complete the welding of the crew pressure vessel.
Although Orion’s readiness date for EM-1 was not formally part of the
KDP-C milestone commitment, engineers continue to work toward a
commitment for SLS and GSDO to be ready for the uncrewed mission in fall
2018, and NASA will set an integrated launch date after GSDO’s critical
design review is completed.
