Finally, we calculate the theoretical 2D and slab turbulence pressure, finding that the theoretical slab pressure is very similar to that observed by PSP. The theoretical NI/slab results are very similar to PSP measurements, which is a consequence of the highly magnetic field-aligned radial flow ensuring that PSP can measure slab fluctuations and not 2D ones. The image was taken by the Full Sun Imager of the Extreme Ultraviolet Imager onboard the Solar Orbiter. The normalized cross helicity and normalized residual energy observed by PSP are 0.96 and −0.07, respectively, indicating that the slow solar wind is very Alfvénic. The solar eruption took place on February 15 and extended millions of miles into space. Similarly, we find that the theoretical solar wind density is consistent with the remotely and in-situ observed solar wind density. Statistics The Solar Orbiter spacecraft in numbers 1,720kg: Launch mass 4: Instruments to sense the solar wind around the spacecraft 6: Telescopes to observe the Sun’s surface 42 million km: Closest approach to the Sun 600C: Maximum design heat exposure to the spacecraft heatshield 1. We solve for the speed of the orbit, noting that m cancels, to get the orbital speed vorbit GME r. The gravitational force supplies the centripetal acceleration. We present the design and pre-launch performance of the Solar Orbiter Heliospheric Imager (SoloHI) which is an instrument prepared for inclusion in the ESA/NASA Solar Orbiter mission, currently scheduled for launch in 2020. We find theoretically and observationally that the solar wind speed accelerates rapidly within 3.3–4 R⊙ and then increases more gradually with distance.

Solar Orbiter will allow, for the first time, to study the Sun at a distance of 0,28 UA (1 UA is the distance between. The Metis/SolO instrument remotely measures the solar wind speed finding a range from 96 to 201 km s−1, and PSP measures the solar wind plasma in situ, observing a radial speed of 219.34 km s−1. obtained by the Solar Orbiter (SolO) and Parker Solar Probe (PSP) pioneering. The launch is scheduled for February 2020. The combined observations describe the evolution of a slow solar wind plasma parcel from the extended solar corona (3.5–6.3 R⊙) to the very inner heliosphere (23.2 R⊙). We present the first theoretical modeling of joint Parker Solar Probe (PSP)–Metis/Solar Orbiter (SolO) quadrature observations.
