These booms have a specific mass in excess of 100 g/m and are longer than 120 m. Lightweight Booms: The current study baseline is utilizing lightweight booms to provide rigidity to the structure. During its required 5 year lifetime it is important that the sail keep its optical properties, as the performance of the sail is directly dependent on the reflectivity of the coating.
Solar Sail Material: The sail material will have to withstand a solar flux of approximately 16 times the flux at Earth. For the IHP the sail area is in excess of 50 000 m 2, which will be very challenging to deploy without causing ruptures, damaging coatings, etc. Solar Sail Deployment: Solar sails require structures that are extremely large and a safe deployment mechanism needs to be developed. The main technologies requiring development are outlined below: The IHP Technology Reference Study is intended to identify the technologies required for a mission to the interstellar Heliopause and beyond. The current mass budget for IHP is given in the table below. The characteristics of the sail can be seen in the table below. The preliminary concept for IHP employs a spinning solar sail. Magnetic field measurements in very low fieldsĮnergy levels, composition, mass, angular and energy distribution of neutral atomsĮnergy levels, mass and composition of dust particles Sample PayloadĮlemental and isotopic composition of plasma and the associated energy levels at temporal composition Closer distances would provide even higher escape velocities, however with the current materials selected for the sail design 0.25 AU distance will be the closest possible distance to keep the sail at the required temperatures. To obtain the required solar system escape velocity the IHP will perform two close flybys of the Sun (at minimum 0.25 AU). With solar sails the IHP can meet these requirements by means of a solar sail with a characteristic acceleration of 1.0 mms -2. To reach the interstellar medium in the shortest possible time the spacecraft will have to be launched in the direction of the heliosphere nose, which is located at 7.5° latitude and 254.5° longitude, in the ecliptic coordinate frame. The IHP mission profile requires the spacecraft to travel a distance of 200 AU from the Sun within 25 years. How does the solar system impact the interstellar medium?.How does the interstellar medium affect the solar system?.What is the nature of the interstellar medium?.The scientific questions that the IHP will aim to answer as it travels towards this region are: The main scientific objective of the IHP is to investigate the interface region between the local interstellar medium and the heliosphere and to truly reach the interstellar medium at 200 AU. Interface between the Heliosphere and Interstellar Medium (ESA & Lotfi Ben Jaffel, Martin Kornmesser and Lars Lindberg Christensen) This challenging mission profile will require a set of enabling technologies that are not only of benefit for this type of mission, but also for missions to the outer planets. This requires that the IHP travel a distance of 200 AU from the Sun.
The main focus is on heliospheric physics in the outer heliosphere and local interstellar medium. This pedal is 100% analog, true bypass and built by entirely by hand in beachy Akron, Ohio.The Interstellar Heliopause Probe (IHP) Technology Reference Study (TRS) investigates the feasibility of a mission to the heliopause region. When in “Vibrato” mode, the dry signal is removed and the Depth controls acts as a volume control. You can also use the Grand Orbiter as a true pitch vibrato with the “Phase/Vibrato” switch. The Resonance provides a wide range of control over regeneration and at higher settings adds a more pronounced and resonant tone.

The Sweep control governs the peak frequency of the phased signal’s tone, turned full clockwise the sweep is lively and intense, whereas turning counter clockwise yields a darker, more laid back peak. The Depth control blends the shifted signal in with the dry signal and controls the intensity of the effect.
The master Rate control fine tunes the speed of the LFO in each of these modes and the flashing red LED acts as a visual indicator, even when the effect is in bypass mode. It has three way toggle switch to select between the ranges of modulation: Rate 1 is slow sweep mode, Rate 2 kills the LFO and allows you to use the Grand Orbiter as a fixed resonant filter and Rate 3 is fast sweep mode. The Grand Orbiter™ is a 4 stage OTA-based phaser with a diverse feature set that can go from stationary and resonant to slow and mellow and on through fast and swirly.
