+ The Energetic Particle Detector (EPD) on Solar Orbiter comprises a suite of four sensor types designed to make in-situ measurements of the spectra, composition, time variation, and directional distribution of energetic particles over an energy range of 2 keV to 500 MeV/n. The main science objective of EPD is to study how solar eruptions produce energetic particle radiation that fills the heliosphere. This can be broken into three studies: 1)How and where energetic particles are injected at the sources and, in particular, what the seed populations are for energetic particles; 2) How and where energetic particles are accelerated at the Sun and in the interplanetary medium; and 3) How energetic particles are released from their sources and distributed in space and time.
+
+The EPD suite is composed of the Supra Thermal Electrons and Protons (STEP) sensor; the Suprathermal Ion Spectrograph(SIS); the Electron Proton Telescopes (EPT); and the High Energy Telescopes (HET). The overall mass of the suite is 15.718 kg, including the Instrument Control Unit (ICU), intraharness, and multilayer insulator. Total power used is 19.7 W. An additional 16.36 W is required for the survival heaters.

+
+ The Extreme Ultraviolet Imager (EUI) is a suite of three instruments with the goal of observing the photosphere, chromosphere and corona in high-resolution at extreme ultraviolet wavelengths to elucidate the link between the solar surface and outer corona. The scientific objectives are to study the origins of solar wind streams and the heliospheric magnetic field; the sources, acceleration mechanisms, and transport processes of solar energetic particles; how coronal mass ejections evolve in the inner heliosphere; and the energetic, dynamic, and fine-scale structure of the Sun's magnetized atmosphere. It will also be making the first images of the Sun from an out-of-ecliptic viewpoint (up to 34 degrees in the extended mission.)
+
+The EUI suite comprises two high-resolution imagers (HRI) and one dual band full-sun imager (FSI). Both HRIs have a field-of-view of 1000 square arcseconds and an angular resolution (2-pixel) of 1 arcsecond using 2048 x 2048 pixel focal plane array detectors. One HRI is centered at 1216 angstroms (Lyman-alpha) with a focal length of 6000 mm, and the other alternates observations between 174 and 335 angstroms with a focal length of 4122.879 mm. The FSI alternates observations between 174 and 335 angstroms with a field-of-view of 5.2 x 5.2 arcdeg and an angular resolution of 9 arcseconds using a 4096 x 4096 focal plane array detector. It has a focal length of 450 mm. All three imagers are mounted on a single optical bench, 900 x 600 x 230 mm, mounted behind the heat shield, and observe through apertures in the shield. The Common Electronics Box, 120 x 300 x 250 mm, is mounted separately inside the spacecraft. Total mass is 18.2 kg and nominal power usage is 32 W.

+ The Solar Orbiter visible light and ultraviolet coronal imager, designated Metis, is an externally occulted solar coronagraph designed to image the off-limb solar corona in visible and ultraviolet light. The goal of the instrument is to observe the structure and dynamics of the full corona from about 1.7 to 9 solar radii. The scientific objectives are to investigate: energy deposition and outflows in the expanding corona; the role of magnetic field lines in channeling the coronal wind; coronal fluctuations and their role in the solar wind acceleration; coronal mass ejection onset and early propagation; eruption of prominences and their propagation in the corona; global evolution of the streamer belt; and acceleration of solar energetic particles.
+
+Metis comprises three operational units, the Metis Optical Unit (MOU), the Camera Power Converter (CPC), and the Metis Processing and Power Unit (MPPU). The MOU consists of an external occultation system, a telescope, a polarimeter, an ultraviolet camera, a visible light camera, and a high-voltage unit. These are contained in a 1430 x 408 x 329 mm envelope mounted behind the sunshield. Metis has two fields of view (FOV), an inner FOV of 1.6 degrees and an outer, non-circular FOV of 2.9 to 3.4 degrees. This gives an FOV of 1.7 to 3.6 solar radii at a perihelion distance of 0.28 AU. The visible light camera uses a 2048 x 2048 pixel CMOS array, it has a spectral range from 580 - 640 nm with an angular resolution of 20 arcseconds and a focal length of 200 mm. The ultraviolet camera consists of a 1000 x 1000 pixel microchannel plate intensifier and has a spectral range from 111.6 - 131.6 nm centered on the Lyman-alpha with an angular resolution of roughly 80 arcseconds and a focal length of 300 mm. The polarimeter measures the linearly polarized solar K-corona with a bandpass of 580 - 640 nm using a polarization modulation package and a relay-optics system. It has an optical magnification of 0.67, an F-number of 4.2, and a 0.5 degree FOV.
+
+According to Greek mythology, Metis, Zeus first spouse and Athena's mother, was the Titaness of all wisdom and knowledge.
+ Solar Orbiter is a mission of international cooperation between the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA), operated by ESA.
+
+The Metis programme is supported by the Italian Space Agency (ASI) under the contracts to the co-financing National Institute of Astrophysics (INAF): Accordo ASI-INAF N. I-043-10-0 and Accordo ASI-INAF & Addendum N. I-013-12-0/1 and under the contracts to the industrial partners: ASI-TASI N. I-037-11-0 and ASI-ATI N.2013-057-I.0.

+ The European Space Agency, ESA, Solar Orbiter mission will study the Sun from a highly elliptical orbit getting as close as 0.28 AU or 42 million km from which it will use a suite of instruments to make high-latitude observations of the Sun and heliosphere, including the magnetic field, energetic particles, solar wind, and transient phenomena.
+
+The Solar Orbiter primary science objectives are to study:
+
+* 1) the drivers of the solar wind and the origin of the coronal magnetic field to determine how solar transients drive heliospheric variability
+* 2) learn how solar eruptions produce the energetic particles that fill the heliosphere
+* 3) how the solar dynamo works and drives connections between the Sun and the heliosphere
+
+Solar Orbiter comprises a 2.5 m ⨯ 3.0 m ⨯ 2.5 m box-shaped bus with two solar panel wings spanning 18 m to supply power. Total launch mass is 1800 kg. There is a 4.4 m instrument boom and three 6.5 m antennas protruding from the spacecraft body. A carbon fiber composite, titanium layered solar shield covers one side of the spacecraft. The shield has apertures for various instruments. The spacecraft is 3-axis stabilized to keep the heat shield oriented towards the Sun. Telemetry is dual X-band through steerable medium and high-gain antennas. Low gain antennas are used in the launch and early orbit phase and are available for backup.
+
+Solar Orbiter carries two types of instruments, in-situ instruments making direct measurements of the heliospheric environment, and remote sensing instruments, which view the Sun and heliosphere from a distance.
+
+The in-situ instruments comprise:
+
+* 1) Energetic Particle Detector, EPD
+* 2) Magnetometer, MAG
+* 3) Radio and Plasma Waves sensor, RPW
+* 4) Solar Wind Plasma Analyser, SWA
+
+The remote-sensing instruments comprise:
+
+* 1) Extreme Ultraviolet Imager, EUI
+* 2) Coronagraph, METIS
+* 3) Polarimetric and Helioseismic Imager, PHI
+* 4) Heliospheric Imager, SoloHI
+* 5) Spectral Imaging of the Coronal Environment, SPICE
+* 6) X-ray Spectrometer/Telescope, STIX
+
+The total massm of the scientific payload is 209 kg.
+
+Solar Orbiter launched from Cape Canaveral Air Force Station on 10 February 2020 at 04:03 UT or at 23:03 Eastern Standard Time, EST, on February 9th. The spacecraft launched on an Atlas 5-411 (AV-087) into a short Earth parking orbit followed by injection into an elliptical heliocentric orbit. The first perihelion will be in June 2020. The mission will use six gravity assist maneuvers during the 7-year nominal mission:

++---------------------------------+
+
+The series of encounters will tilt the spacecraft orbit to an inclination of 25° and will yield an orbit with a perihelion of 0.28 AU, an aphelion of 0.91 AU, and a period of 168 days. Solar Orbiter will make fourteen perihelion passes during the nominal mission. If a three year extended mission is approved, Solar Orbiter will make three more Venus flybys that will bring the inclination to 33°.
