Design Status of Gondola for High-Altitude Planetary Science (GHAPS)

The Gondola for High-Altitude Planetary Science (GHAPS) project was initiated to develop a balloon platform to meet planetary science goals and objectives as outlined in the NASA decadal survey. GHAPS is a first-generation reusable platform design optimized for multiple long-duration flights and planetary science. The gondola design was intended to accommodate infrared (IR) and ultraviolet/visible (UV-Vis) observations, supporting detection of water and carbon dioxide and allowing for long-duration flights to enable time-based studies. It was anticipated that the GHAPS gondola design would evolve over time with changing science demands. This report describes the as-designed configuration and capabilities of the GHAPS gondola.

Balloon gondola diagnostics package

In order to define a new gondola structural specification and to quantify the balloon termination environment, NASA developed a balloon gondola diagnostics package (GDP). This addition to the balloon flight train is comprised of a large array of electronic sensors employed to define the forces and accelerations imposed on a gondola during the termination event. These sensors include the following: a load cell, a three-axis accelerometer, two three-axis rate gyros, two magnetometers, and a two axis inclinometer. A transceiver couple allows the data to be telemetered across any in-line rotator to the gondola-mounted memory system. The GDP is commanded 'ON' just prior to parachute deployment in order to record the entire event.

Flight Performance of the Balloon Gondola Solar Pointing System

The NASA Solar Pointing System (SPS) has made two operational flights since its test flight in April of 1997. This pointing device was conceived and designed to provide ultra-low power gondola pointing primarily for directing gondola-fixed solar panels toward the sun. While typically consuming less than 5 watts, the system is capable of suspending and pointing up to 3400 kg, The SPS has logged over 25 days of mostly continuous operation. The performance data, including power consumption and pointing accuracy for these two successful flights is presented and analyzed. The data is compared to predictions and test flight data Suggestions for further developments and applications including Ultra-Long Duration Balloon (ULDB) are discussed.

Guidelines and Suggestions for Balloon Gondola Design

This paper discusses the current gondola design requirements for the Columbia Scientific Balloon Facility (CSBF). The CSBF is responsible for launching and supporting balloon borne scientific instruments and has some current updated guidelines that will be discussed in this presentation. As the sophistication of Payload systems have increased in size and complexity new guidelines have been implemented in order to make these instruments stay within the acceptable launch risks. Additionally, there is a requirement to submit a proper stress analysis report that states the flight design requirements have been met. Suggestions are discussed in this presentation that establish the proper guidelines to submit these.

LuZip: Lunar Zip-line, Gondola and Cable-based Transportation for Artemis Moon Missions Mobility and Dust Avoidance

Under the Artemis program, NASA plans to return to the surface of the Moon, this time to stay. The Apollo missions identified dust as a major challenge for operations on the lunar surface. This includes traveling from point to point. There have been efforts to develop technologies that prevent dust from entering equipment, making equipment more resilient to dust and improving dust removal. However, operating effectively in the dusty environment for long durations is still an open problem. Here, we explore the use of cable-based transportation, gondolas and zip-lines to stay above the dust for equipment and material transfer as well as human excursions. The advantages and disadvantages, potential architectures, propulsion and materials are discussed. Steps towards infusion into the already ongoing Artemis program are also presented.

The stellar and solar tracking system of the Geneva Observatory gondola

Sun and star trackers have been added to the latest version of the Geneva Observatory gondola. They perform an image motion compensation with an accuracy of plus or minus 1 minute of arc. The structure is held in the vertical position by gravity; the azimuth is controlled by a torque motor in the suspension bearing using solar or geomagnetic references. The image motion compensation is performed by a flat mirror, located in front of the telescope, controlled by pitch and yaw servo-loops. Offset pointing is possible within the solar disc and in a 3 degree by 3 degree stellar field. A T.V. camera facilitates the star identification and acquisition.

Development of an Energetic X-Ray Imaging Telescope Experiment (EXITE) and Associated Balloon Gondola System

This is the Final Report for grant NAGW-624, which was our original grant to develop the Energetic X- ray Imaging Telescope Experiment (EXITE) and Associated Balloon Gondola. The EXITE grant was changed over to a new grant (from GSFC), NAG5-5103, beginning in FY97 and is currently very much continuing under that grant. The Final Report presented here then covers the EXITE development under the original grant, which in fact continued (with a 1 year no-cost extension) through December 31, 1997.

Development of EXITE3, Imaging Detectors and a Long Duration Balloon Gondola

In this Report we summarize the work conducted for the EXITE program under grant NAG5-5103. This grant supported the ongoing EXITE program at Harvard for the development of imaging hard x-ray detectors and telescopes over the 3 year period 1997-2000 with a one year extension to 2001 to transition to the next SR&T grant in this program. Work was conducted in three major parts: analysis of the EXITE2 balloon flight data (from our May 1997 flight); development of pixellated imaging Cd-Zn-Te detector arrays and readout systems for the proposed EXITE3 detector and telescope; and development of systems for a Long Duration Balloon (LDB) gondola. Progress on all three major aspects of this research is summarized for each of the years of this grant.

Thermal Design and Analysis of the Optical Telescope Assembly for the Gondola for High Altitude Planetary Science

The NASA Gondola for High Altitude Planetary Science (GHAPS) project is an effort to design, build, and fly a balloon-borne platform for planetary science missions. GHAPS observations will be in the 300 nm to 5 micron wavelength region covering UV, visible, and near-mid IR. The primary element of the project is the Optical Telescope Assembly (OTA). It is a one meter aperture narrow-field-of-view telescope that contains the primary and secondary mirrors, the support system/metering structure, a secondary mirror focusing system, baffles, and insulation. This paper presents the thermal design and analysis that has been done to support the design of the OTA. A major part of the thermal analysis was bounding the flight environment for the six potential Columbia Scientific Balloon Facility launch sites. These analyses were used to give input into the Structural Thermal Optical Performance (STOP) analysis of the telescope. Also the analysis was used to select heater sizes for the few OTA associated electronic components. Currently the telescope is scheduled to have its first flight in 2019.

Gondola For High Altitude Planetary Science (GHAPS) Guide System Trade Study

The Gondola for High-Altitude Planetary Science (GHAPS) project is a balloon-borne astronomical observatory designed operate in the ultraviolet, Visible, and near-mid infrared spectral region. The GHAPS Optical Telescope Assembly (OTA) is designed around a 1-m aperture narrow field-of-view telescope with near-diffraction-limited performance. GHAPS will utilize Wallops Arc-Second Pointing System (WASP) for pointing the OTA with an accuracy of 1 arcsec or better. WASP relies heavily on a self-contained star tracker assembly to determine the OTA line of sight. Preliminary structural analysis indicates that potential misalignments could be present between the OTA line of sight and the star tracker FOV center during the expected flight conditions that could compromise GHAPS pointing accuracy.

Gondola for High Altitude Planetary Science (GHAPS) Telescope Secondary Mirror Positioning Hexapod Issues and Alternatives

Active positioning of the GHAPS secondary telescope mirror is desired to correct for rigid body deflections due to temperature variations and gravity sag in the telescope structure that may impact optical performance. The current design concept for the secondary mirror mount uses a Commercial-Off -the-Shelf hexapod for mirror positioning and fine adjustment. The Hexapod specification states that motions as small as 0.1 microns along the optical axis and 2 microns perpendicular to the optical axis will cause optical aberrations that will require correction by repositioning the secondary mirror. In addition, the secondary mirror mount and positioning system must survive a 15g shock of parachute opening and landing during the instrument recovery operation. The secondary mirror positioning system must operate at a minimum specified temperature of -50 C. The telescope operates in the IR and the secondary mirror mount and positioning device is in the metering path between the primary and secondary mirrors. I2R losses in positioning system actuator devices, which may cause heating of the positioning system and secondary mirror, must be minimized due to the previously mentioned alignment sensitivity and the viewing spectrum of interest. The GHAPs project was cancelled on June 30, 2017. The purpose of this study is to address some of the issues identified with the hexapod secondary mirror positioning system and identify alternative approaches. This information may be used if the project is re-started at a later date.
