International Ultraviolet Explorer (IUE) Post Launch Report 2
2019Co-Authors: NasaAbstract:The International Ultraviolet Explorer (IUE), an Explorer class ultraviolet astronomy mission, is an international cooperative program between the United States, the United Kingdom (UK), and the European Space Agency (ESA) which provides for a single launch into geosynchronous orbit to conduct spectral distribution studies of celestial and solar system ultraviolet sources. The spacecraft and scientific instruments were designed and fabricated at the Goddard Space Flight Center. The spectrograph camera was provided by the UK; ESA provided the solar array as well as the European ground station. The IUE observatory system was designed to functionally resemble a ground-based optical observatory at which guest observers could execute observing programs in real time. Observatory performance substantially exceeded design and mission objectives. The secondary mission objectives were also met.

Magellan Post Launch Mission Operation Report
2019Co-Authors: NasaAbstract:Magellan was successfully launched by the Space Shuttle Atlantis from the Kennedy Space Center at 2:47 p.m. EDT on May 4, 1989. The Inertial Upper Stage (IUS) booster and attached Magellan Spacecraft were successfully deployed from Atlantis on Rev. 5 as planned, at 06:14 hrs Mission Elapsed Time (MET). The two IUS propulsion burns which began at 07:14 hrs MET and were completed at 07:22 hrs MET, placed the Magellan Spacecraft almost perfectly on its preplanned trajectory to Venus. The IUS was jettisoned at 07:40 hrs MET and Magellan telemetry was immediately acquired by the Deep Space Network (DSN). A spacecraft trajectory correction maneuver was performed on May 21 and the spacecraft is in the planned standard cruise configuration with all systems operating nominally. An initial attempt was made to launch Atlantis on April 28, 1989, but the launch was scrubbed at T-31 sec due to a failure of the liquid hydrogen recirculation pump on Space Shuttle Main Engine #1. The countdown had proceeded smoothly until T-20 min when the Magellan radio receiver "locked-on" the MIL 71 Unified S-Band (USB) transmission as the transmitter power was increased fro 2 kw to 10 kw in support of the orbiter launch. During the planned hold at T-9 min, the USB was confirmed as the source of the receiver "lock" and Magellan's launch readiness was reaffirmed. In addition a five-minute extension of the T-9 hold occurred when a range safety computer went off-line, creating a loss of redundancy in the range safety computer network. Following resumption of the countdown, both the orbiter and Magellan flows proceeded smoothly until the launch was scrubbed at T-31 sec.

San Marco C-2 Post Launch Report No. 2
2019Co-Authors: NasaAbstract:San Marco C-2 is declared a success based upon the results of the mission with respect to the approved prelaunch objectives. On February 18, 1974, San Marco C-2 was launched by a Scout vehicle from the San Marco Range into an elliptical equatorial orbit. The payload consisted of three scientific instruments, two U. S. and one Italian, designed to obtain measurements of the diurnal variations of the equatorial neutral atmosphere density, composition, and temperature and to use these data for correlation with Explorer 51 (AE-C) data for studies of the physics and dynamics at the thermosphere. After 23 months in orbit, more than 17 diurnal cycles of data on the density, composition, and temperature of the equatorial thermosphere have been obtained, clearly meeting the primary mission objectives. Both U.S. scientific instruments continue to acquire data but the Italian air drag balance, which malfunctioned shortly after launch, has never performed properly. Studies and correlations of data from AE-C and San Marco C-2 have begun and will continue as data acquired from the two satellites are processed and analyzed.

STS-114: Post Launch MMT Briefing
2018Co-Authors: NasaAbstract:Bill Parsons, Space Shuttle Program Manager, and Wayne Hill, Deputy Manager of the Space Shuttle Program, and Chair of the Mission Management Team talks about the flight day 2 of the Discovery. Bill noted that flight operations are extremely going on well. He also explained an unexpected debris event on a power ramp little ways down where LH2 ramp begins. Before flight and based from technical data, slight modifications were done on the power ramp to ensure safety of return to flight. Bill also noted that STS-114 is a test flight; all data collected and brought back by the crew will be analyzed to ensure that all information needed is sufficient to work on faults and defects and to make appropriate repairs. Wayne discussed on flight safety. He emphasized the need to thoroughly inspect the thermal protection system of the Orbiter to ensure safe entry. Inspection of still photographs from the ISS and the boom sensor system scan are the primary means to understand engineering data in terms of the immediate flight safety. He also reported accomplishments for the day such as survey of the Orbiter boom system, all the wing leading edge, RCC panels and the nose cap, to make sure these are in good shape and working well, and re-emphasized that these are primary methods to clear the thermal protection system of the Orbiter to prove that it is safe to come home on this flight.

STS-35: Post Launch News Conference
2017Co-Authors: NasaAbstract:Live footage shows the question and answer session of the Post Launch News Conference. The Panelists address questions from NASA Centers such as Goddard Space Flight Center and Kennedy Space Center (KSC), and from various audience participants. The status of the launch of STS-35 is discussed. Also discussed are the liquid oxygen malfunctions, helium leakage, and photographic optical tracking during the daytime.

ibm as 400 new product launch process ensures satisfaction
Long Range Planning, 1992Co-Authors: Victor Tang, Emilio CollarAbstract:Abstract The introduction of a new product is risky and complex in rapidly changing, contemporary markets. Most current practices do not significantly reduce risk or accelerate product diffusion. This paper discusses the major flaws of current practices and presents a new launch paradigm. In essence, the product launch should be part of an integrated ‘closed-loop’ strategic process whose goals are to ensure market success, continuous learning and improvement. This requires that all the major stakeholders should work as a tightly-integrated team to create the market conditions that will accelerate the product's acceptance. The stakeholders—product developers, customers and allies—must develop co-ordinated strategies for pre-launch, launch and Post-Launch programmes. A model of the new launch paradigm is presented and its application and characteristics are illustrated using as an example the IBM AS/400. The product helped IBM Rochester to win the U.S. Malcolm Baldrige National Quality Award, and was launched in over 120 countries with hundreds of business partners.

PHEBUS on Bepi-Colombo: Post-Launch Update and Instrument Performance
Space Science Reviews, 2020Co-Authors: Eric Quémerais, Jean-yves Chaufray, Dimitra Koutroumpa, François Leblanc, Aurélie Reberac, Benjamin Lustrement, Christophe Montaron, Jean-françois Mariscal, Nicolas Rouanet, Ichiro YoshikawaAbstract:The Bepi-Colombo mission was launched in October 2018, headed for Mercury. This mission is a collaboration between Europe and Japan. It is dedicated to the study of Mercury and its environment. It will be inserted into Mercury orbit in December 2025 after a 7-year long cruise. Probing of Hermean Exosphere By Ultraviolet Spectroscopy (PHEBUS) is an ultraviolet Spectrograph and is one of the 11 instruments on-board the Mercury Planetary Orbiter (MPO). It is dedicated to the study of the exosphere of Mercury, its composition, dynamics and variability and its interface with the surface of the planet and the solar wind. The PHEBUS instrument contains four distinct detectors covering the spectral range from 55 nm up to 315 nm and two additional narrow windows at 404 nm and 422 nm. It also has a one-degree of freedom mechanism that allows observations along a cone with an half angle of 80∘ 80 ∘ . This paper follows a detailed presentation of the PHEBUS instrument design that was presented by Chassefière et al. (Planet. Space Sci. 58:201–223, 2010). Here we present an update of the science objectives and measurement requirements following the results published by the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) mission. We also present results of the ground calibration campaigns of the flight unit that is currently on-board MPO. In the last part, we present some details of the observations that will be performed during the cruise to Mercury, such as stellar observation campaigns, interplanetary background observations and planetary flybys.
