The ExoMars Schiaparelli Entry, Descent and Landing Demonstrator Module (EDM) System Design
Bayle, Olivier; Ball, Andrew J.; Blancquaert, Thierry +3 more
The Entry, Descent and Landing Demonstrator Module (EDM) named Schiaparelli, was the ESA-led Mars lander element of the ESA-Roscosmos ExoMars 2016 mission. Following launch on 14 March 2016 with the ExoMars Trace Gas Orbiter (TGO) and cruise to Mars, Schiaparelli separated for encounter with Mars to demonstrate entry, descent and landing technolog…
Solar System Science with the Orbiting Astronomical Satellite Investigating Stellar Systems (OASIS) Observatory
Hartogh, Paul; Anderson, Carrie M.; Tielens, Alexander +6 more
The overarching theme of the Orbiting Astronomical Satellite for Investigating Stellar Systems (OASIS), an Astrophysics MIDEX-class mission concept, is Following water from galaxies, through protostellar systems, to Earth's oceans. The OASIS science objectives address fundamental questions raised in "Pathways to Discovery in Astronomy and Astrophy…
Observations of the Solar F-Corona from Space
Llebaria, A.; Lamy, P. L.; Gilardy, H.
We present a review of the observations of the solar F-corona from space with a special emphasis of the 25 years of continuous monitoring achieved by the LASCO-C2 and C3 coronagraphs. Our work includes images obtained by the navigation cameras of the Clementine spacecraft, the SECCHI/HI-1A heliospheric imager onboard STEREO-A, and the Wide Field I…
Observations and Modeling of Martian Auroras
Haider, S. A.; Bougher, S. W.; Schneider, N. M. +4 more
Observations of planetary auroras form a new area of planetary exploration from space, especially for nonmagnetic planets since various kinds of auroras like Discrete, Proton and Diffuse auroras have been observed at Mars. We review the latest results of Martian auroras obtained by the instruments (1) SPICAM (Spectroscopy for the Investigation of …
Navigation and Orbit Estimation for New Horizons' Arrokoth Flyby: Overview, Results and Lessons Learned
Weaver, Harold A.; Kavelaars, J. J.; Gwyn, Stephen D. J. +18 more
The New Horizons mission performed a successful flyby of Arrokoth, a distant Kuiper-Belt Object, on January 1, 2019, representing the farthest planetary encounter to date. The navigation strategy and performance required to deliver the spacecraft to the desired flyby target were driven by a number of challenges including those related to Arrokoth'…

BepiColombo - Mission Overview and Science Goals
Orsini, S.; Quemerais, E.; Glassmeier, K. -H. +28 more
BepiColombo is a joint mission between the European Space Agency, ESA, and the Japanese Aerospace Exploration Agency, JAXA, to perform a comprehensive exploration of Mercury. Launched on 20th October 2018 from the European spaceport in Kourou, French Guiana, the spacecraft is now en route to Mercury.
Slow-Mode Magnetoacoustic Waves in Coronal Loops
Reale, Fabio; Srivastava, Abhishek K.; Ofman, Leon +3 more
Rapidly decaying long-period oscillations often occur in hot coronal loops of active regions associated with small (or micro-) flares. This kind of wave activity was first discovered with the SOHO/SUMER spectrometer from Doppler velocity measurements of hot emission lines, thus also often called "SUMER" oscillations. They were mainly interpreted a…
Magnetohydrodynamic Waves in Open Coronal Structures
Tian, H.; Wang, T. J.; Banerjee, D. +8 more
Modern observatories have revealed the ubiquitous presence of magnetohydrodynamic waves in the solar corona. The propagating waves (in contrast to the standing waves) are usually originated in the lower solar atmosphere which makes them particularly relevant to coronal heating. Furthermore, open coronal structures are believed to be the source reg…
The BepiColombo Planetary Magnetometer MPO-MAG: What Can We Learn from the Hermean Magnetic Field?
Balogh, A.; Glassmeier, K. -H.; Nakamura, R. +29 more
The magnetometer instrument MPO-MAG on-board the Mercury Planetary Orbiter (MPO) of the BepiColombo mission en-route to Mercury is introduced, with its instrument design, its calibration and scientific targets. The instrument is comprised of two tri-axial fluxgate magnetometers mounted on a 2.9 m boom and are 0.8 m apart. They monitor the magnetic…
