“…We believe, that a stereoscopic view on CMEs incorporated in ELEvoHI will improve the arrival time predictions substantially. Therefore, we strongly support ESA's L5 mission, equipped with a heliospheric imager (Kraft et al., 2017; Lavraud et al., 2016), and an additional heliospheric imager at L1. Fortunately, the upcoming Earth‐orbiting PUNCH mission (launch planned in 2023) will also possess wide‐angle white‐light heliospheric imagers, as well as a coronagraph, and will be able to provide additional observations of CMEs.…”

“…Certainly, more multipoint HI observations would also be helpful, which are currently not possible as data from STEREO B is not available. Future missions carrying heliospheric imagers include NASA's recently launched Parker Solar Probe (Fox et al, ) with its WISPR instrument (Vourlidas et al, ), ESA's Solar Orbiter mission (Müller et al, ) currently scheduled to launch in 2020 with its SoloHI (Howard et al, ), as well as a possible future mission to the L5 Lagrange point (proposed by, e.g., Gopalswamy et al, ; Kraft et al, ; Lavraud et al, ; Vourlidas, ).…”

Tracking and Validating ICMEs Propagating Toward Mars Using STEREO Heliospheric Imagers Combined With Forbush Decreases Detected by MSL/RAD

The Radiation Assessment Detector (RAD) instrument onboard the Mars Science Laboratory (MSL) mission's Curiosity rover has been measuring galactic cosmic rays (GCR) as well as solar energetic particles (SEP) on the surface of Mars for more than 6 years since its landing in August 2012. The observations include a large number of Forbush decreases (FD) caused by interplanetary coronal mass ejections (ICMEs) and/or their associated shocks shielding away part of the GCR particles with their turbulent and enhanced magnetic fields while passing Mars. This study combines MSL/RAD FD measurements and remote tracking of ICMEs using the Solar TErrestrial RElations Observatory (STEREO) Heliospheric Imager (HI) telescopes in a statistical study for the first time. The large data set collected by HI makes it possible to analyze 149 ICMEs propagating toward MSL both during its 8-month cruise phase and after its landing on Mars. We link 45 of the events observed at STEREO-HI to their corresponding FDs at MSL/RAD and study the accuracy of the ICME arrival time at Mars predicted from HI data using different methods. The mean differences between the predicted arrival times and those observed using FDs range from −11-5 hr for the different methods, with standard deviations between 17 and 20 hr. These values for predictions at Mars are very similar compared to other locations closer to the Sun and also comparable to the precision of some other modeling approaches.

Space Weather, 17, 586-598. https://doi.Mars, we will also directly compare these data at the two planets for better understanding their properties and interplanetary propagations. For up to about six events from this catalog, the ICME and FD properties can be better studied by also taking into account in situ measurements of solar wind and magnetic field from the MAVEN spacecraft that arrived at Mars in late 2014. However, MAVEN can only measure the upstream solar wind intermittently due to the spacecraft orbit (as discussed in section 1), resulting in frequent gaps in the data.Nevertheless, our current results are important for the understanding of space weather, but of course also for the development of future deep space missions and human spaceflight to Mars, where accurate predictions of ICMEs, their associated shocks and accompanying SEP events, and their impact are essential.

“…Hence, under the SSA program ESA is also expanding the use of data provided by existing missions (e.g., PROBA-2, SOHO, Gaia, SWARM), but also studying the deployment of new SW sensors to be hosted on future missions, and supporting the development of a new mission called "Lagrange" (Hapgood, 2017). This mission will be entirely dedicated to SW monitoring, and will consist of two satellites placed in orbit around the Sun-Earth Lagrangian points L1 and L5; the mission development is now in Phase B, and its launch is planned for 2025, when the development of SW services mentioned above will also be ready to integrate the data coming from "Lagrange" mission (Kraft, 2017).…”

Possible Advantages of a Twin Spacecraft Heliospheric Mission at the Sun-Earth Lagrangian Points L4 and L5

After the launch of STEREO twin spacecraft, and most recently of Solar Orbiter and Parker Solar Probe spacecraft, the next mission that will explore Sun-Earth interactions and how the Sun modulates the Heliosphere will be the “Lagrange” mission, which will consist of two satellites placed in orbit around L1 and L5 Sun-Earth Lagrangian points. Despite the significant novelties that will be provided by such a double vantage point, there will be also missing information, that are briefly discussed here. For future heliospheric missions, an alternative advantageous approach that has not been considered so far would be to place two twin spacecraft not in L1 and L5, but in L4 and L5 Lagrangian points. If these two spacecraft will be equipped with in situ instruments, and also remote sensing instruments measuring not only photospheric but also coronal magnetic fields, significant advancing will be possible. In particular, data provided by such a twin mission will allow to follow the evolution of magnetic fields from inside the Sun (with stereoscopic helioseismology), to its surface (with classical photospheric magnetometers), and its atmosphere (with spectro-polarimeters); this will provide a tremendous improvement in our physical understanding of solar activity. Moreover, the L4-L5 twin satellites will take different interesting configurations, such as relative quadrature, and quasi-quadrature with the Earth, providing a baseline for monitoring the Sun-to-Earth propagation of solar disturbances.
