Engineers Tuck NuSTAR in its Nose Cone

Technicians at Vandenberg Air Force Base in central California are placing the two halves of the rocket nose cone, or fairing, around NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), in preparation for its launch. The launch is scheduled for no earlier than March 21.

The fairing will hold the observatory safely in place atop its Orbital Sciences Corporation rocket, a Pegasus XL. The rocket will blast off from the L-1011 "Stargazer" aircraft, also from Orbital, near Kwajalein Atoll in the central Pacific Ocean. During its ride to space, the fairing will split open like a clamshell, exposing NuSTAR before it is ultimately carried to its final orbit around Earth.

The fairing installation is a two-day process scheduled to be completed on Saturday, March 3.

NuSTAR will study everything from our sun to massive black holes buried in the hearts of galaxies. It will be the first space telescope to capture sharp images in high-energy X-rays, giving astronomers a new tool for understanding the most energetic objects and events in our universe.

NuSTAR is a Small Explorer mission led by the California Institute of Technology and  managed by NASA's Jet Propulsion Laboratory, both in Pasadena, Calif., for NASA's Science Mission Directorate. The spacecraft was built by Orbital Sciences Corporation, Dulles, Va. Its instrument was built by a consortium including Caltech; JPL; the University of California, Berkeley; Columbia University, New York; NASA's Goddard Space Flight Center in Greenbelt, Md.; the Danish Technical University in Denmark; Lawrence Livermore National Laboratory, Calif.; and ATK Aerospace Systems, Goleta, Calif. NuSTAR will be operated by UC Berkeley, with the Italian Space Agency providing its equatorial ground station located at Malindi, Kenya. The mission's outreach program is based at Sonoma State University, Calif. NASA's Explorer Program is managed by Goddard. JPL is managed by Caltech for NASA.

NASA March 13 NuSTAR Media Briefing Postponed
March 12, 2012

PASADENA, Calif. -- The Tuesday, March 13, media briefing to discuss the upcoming launch of the Nuclear Spectroscopic Telescope Array (NuSTAR) has been postponed. The spacecraft will lift off on an Orbital Sciences Pegasus XL rocket, which will be released from an aircraft originating from the Kwajalein Atoll in the Marshall Islands.

The mission's Flight Readiness Review (FRR) is being rescheduled for no earlier than Thursday, March 15, to allow time for a review of data and simulations to qualify software associated with a new Pegasus flight computer.

A revised launch date will be set at the FRR. A pre-launch media briefing will be rescheduled after the FRR is complete.

NuSTAR will use advanced optics and detectors, allowing astronomers to observe the high-energy X-ray sky with much greater sensitivity and clarity than any mission flown before. The mission will advance our understanding of how structures in the universe form and evolve. It will observe some of the hottest, densest and most energetic objects in the universe, including black holes, their high-speed particle jets, ultra-dense neutron stars, supernova remnants and our sun.

MEDIA ADVISORY: M12-045

LAUNCH OF NASA'S NUSTAR MISSION POSTPONED

WASHINGTON -- The planned launch of NASA's Nuclear Spectroscopic
Telescope Array (NuSTAR) mission has been postponed after a March 15
launch status meeting. The launch will be rescheduled to allow
additional time to confirm the flight software used by the launch
vehicle's flight computer will issue commands to the rocket as
intended.

The spacecraft will lift off on an Orbital Sciences Pegasus XL rocket,
which will be released from an aircraft taking off from the Reagan
Test Site on the Kwajalein Atoll in the Marshall Islands. The time
required to complete the software review has moved NuSTAR beyond the
March timeframe currently available on the range at Kwajalein. In the
interim, NASA will coordinate with the launch site to determine the
earliest possible launch opportunity. This is expected to be within
the next two months.

NuSTAR will use advanced optics and detectors, allowing astronomers to
observe the high-energy X-ray sky with much greater sensitivity and
clarity than any mission flown before. The mission will advance our
understanding of how structures in the universe form and evolve. It
will observe some of the hottest, densest and most energetic objects
in the universe, including black holes, their high-speed particle
jets, ultra-dense neutron stars, supernova remnants, and our sun.

Launch of NASA X-ray telescope targeted for June

NASA's NuSTAR X-ray astrophysics observatory, grounded in March by concerns with its Pegasus rocket, will have an opportunity to launch in June from a remote Pacific military base, space agency officials said Tuesday.

Engineering reviews of the air-launched Orbital Sciences Corp. Pegasus rocket continue, according to NASA, with officials focusing on software to be used by a new computer flying on the Pegasus for the first time.

The reviews were not finished in time for the $165 million mission to be ready before the end of a launch window in late March.

"We're still working on the flight software program," said George Diller, a spokesperson at the Kennedy Space Center.

The clamshell-like nose cone on the Pegasus rocket has been cleared for launch. Engineers were studying commonality between the Pegasus payload fairing and the shroud on the ground-launched Taurus rocket, another Orbital Sciences vehicle, which failed due to fairing separation problems on back-to-back flights in 2009 and 2011.

The Pegasus booster has flown 40 times, and the upcoming launch will mark the 25th mission of the Pegasus XL configuration, which features more powerful rocket motors than earlier versions.

The Pegasus XL rocket is fully assembled inside a hangar at Vandenberg Air Force Base, Calif. Technicians will tow the rocket to the base's runway a few weeks before launch and bolt it to an L-1011 carrier aircraft, which will fly the Pegasus and NuSTAR payload to Kwajalein Atoll in the Marshall Islands.

The L-1011 jumbo jet will drop the rocket about 40,000 feet over the Pacific Ocean, and the three-stage, winged Pegasus will light to propel the 800-pound NuSTAR satellite into a 340-mile-high orbit.

The U.S. Army's Reagan Test Site should give NASA a specific launch date in a few days. The space agency has requested to launch in the first week of June if possible.

While officials wait for the next launch opportunity, workers will remove the Pegasus payload fairing next week for testing of the NuSTAR spacecraft. Engineers will install an updated flight program into the Pegasus computer when the software analysis is finished, according to Diller.

The NuSTAR mission will be the first flight of the computer on a Pegasus rocket.

NuSTAR stands for the Nuclear Spectroscopic Telescope Array.

The spacecraft will deploy a 33-foot boom with X-ray optics a week after launch and begin its science mission a few weeks later.

The mission will explore the high-energy X-ray universe for two years, probing the supermassive black hole at the center of the Milky Way galaxy, surveying for collapsed dead stars, and studying the exchange of heat between the sun and its million-degree atmosphere.

Так и не запустили!

США. Отсрочка запуска КА NuSTAR на неопределенный срок.
По сообщению NASA от 16 марта 2012 года, запуск астрономической обсерватории NuSTAR из района а. Кваджелейн, который был запланирован на 21 марта 2012 года, в очередной раз отсрочен на неопределенный период из-за вероятных проблем с передачей команд программного обеспечения ракеты «Пегас XL» на борт ракеты.
Как сообщается, потребуется дополнительное время для проверки летного программного обеспечения, установленного на компьютере ракеты, из-за чего будет пропущено окно запуска для КА NuSTAR, в связи с чем ориентировочная дата запуска не сообщается.
Ракета «Пегас XL» была построена компанией Orbital Sciences Corp, которая также обеспечивает ее управление. Как известно, на счету ракет «Пегас» имеются несколько аварийных запусков.

Программа NuSTAR отличается от проектов подобного рода тем, что на КА установлен фокусирующий телескоп для регистрации высокоэнергетических частиц в диапазоне 6-79 кэВ жесткого рентгеновского излучения. По чувствительности он на два порядка превышает возможности воспринимающих приборов таких действующих космических обсерваторий, как XMM-Newton и Chandra (см. рисунок) и аппаратов для исследования Солнца. КА NuSTAR оснащен приборами с зеркалами скользящего отражения, раскладной мачтой и новейшими датчиками на основе теллурида кадмия и цинка. Приборы для этого КА разработаны консорциумом организаций, в состав которого входит Калифорнийский технологический институт. Руководителем программы является Лаборатория JPL.

NuSTAR (см. рисунок) был разработан консорциумом организаций, включающим Калифорнийский технологический институт (КТИ). Руководство программой возложено на Лабораторию JPL. Заказчиком программы является Центр Годдарда. Целевая аппаратура  изготовлена компанией Orbital Sciences Corp. при участии института КТИ, а раздвижная мачта – компанией АТК-Goletа (Калифорния). Покрытие для оптической (фокусирующей) системы КА NuSTAR разработано Техническим университетом Дании (Копенгаген), а технология монтажа создана Колумбийским университетом (Нью-Йорк).
Оптическую систему КА в течение 14 лет разрабатывала группа ученых Центра Годдарда во главе с У. Чаном (Zhang). Эта система состоит из 9 тыс. отдельных зеркальных сегментов. Толщина зеркал составляет 200 мкм, что в 100 раз тоньше зеркал, установленных на КА Chandra. Зеркала сделаны из плоских гладких облегченных стеклянных пластин, изогнутых в виде параболы. Эти элементы установлены в фокусирующем модуле таким образом, чтобы высокоэнергетические рентгеновские фотоны скользили по их поверхности, а не проходили через них (зеркала Вольтера). Заготовки для этих элементов изготавливались в лаборатории, которой руководил У. Чан.
Для получения необходимой изогнутой формы тонкие стеклянные пластины помещались в специальную изложницу и затем нагревались в печи до температуры около 1100
