Position description

POSITION DESCRIPTION
The Space Sciences Laboratory (SSL) at the University of California, Berkeley, seeks applicants for Postdoctoral Scholar position(s). SSL has a long history of developing and operating space instruments and full missions and seeks to hire the next generation of scientists and engineers to continue this legacy of research in space, to advance our current capabilities and to take advantage of numerous recent developments in space science and technology that enable new scientific discoveries. SSL currently seeks energetic, independent and qualified candidates to support NASA Helio-physics and/or Planetary missions in scientific research and/or hardware development mentored by their respective PI's. The specific projects that are hiring are as follows.

The Ionospheric Connection Explorer (ICON) is a NASA Explorer Mission that has been on orbit since late 2019, collecting ground-breaking measurements of thermospheric and ionospheric densities, temperatures and velocities at low to-middle latitudes. These can be used for investigations of topics such as ion neutral coupling in planetary atmospheres, atmospheric wave generation/propagation, geomagnetic storm effects, and lower-atmospheric forcing of Geospace.

The Solar PolArization and Directivity X-Ray Experiment (PADRE) is a 12U Cubesat observatory that will observe the Sun in hard X-ray (HXRs) from low earth orbit, with a planned launch in 2026. PADRE will investigate the accelerated electron angular distribution in solar flares. These observations will provide a unique opportunity to make stereoscopic X-ray observations and measure the electron anisotropy of individual flares confidently for the first time. PADRE has one science objective: determine the angular distribution of accelerated electrons from standalone and joint Solar Orbiter/STIX observations. This will allow the determination of the angular distribution of flare-accelerated electrons.

The Parker Solar Probe (PSP), a mission to touch the Sun, was launched in August 2018 to unlock the mysteries of the Sun's corona and solar wind. PSP has made 11 solar encounters so far, producing world-class measurements of the solar wind in the Sun’s environment and inner heliosphere. SSL plays a lead role on the PSP science and instrumentation teams for The Solar Wind Electrons Alphas and Protons (SWEAP) and FIELDS investigations. SWEAP makes measurements of electrons, protons and helium ions and their properties such as density, velocity and temperature using electrostatic analyzers and a Faraday Cup. FIELDS consists of fluxgate and search coil magnetometers and 5 plasma voltage sensors and makes direct measurements of electric and magnetic fields, radio waves, Poynting flux, absolute plasma density and electron temperature. These two suite of instruments have collected unprecedented in-situ measurements to investigate the dynamics of solar coronal heating and solar wind acceleration.

HERMES (Heliophysics Environmental and Radiation Measurement Experiment Suite) is a suite of instruments that is mounted on the upcoming Lunar Gateway and will serve as a Heliospheric science experiment and a Space Weather station. The lunar gateway itself is a space station that is planned to be in a cislunar, near rectilinear halo orbit (NRHO) orbit around the moon with a short-term habitation module for humans and a science laboratory. For this mission, the SSL is building the ion sensor, called SPAN-Ion, which will provide the science payload with measurements of the ambient ions to measure definitive atmospheric loss around Earth and solar wind acceleration.

The Lunar Surface Electromagnetics Experiment (LuSEE)is a payload in development for a lunar landing as part of NASA’s Commercial Lunar Payload Services (CLPS) program. The LuSEE program consists of two payloads for separate landers: one to the Schroedinger Basin near the lunar South Pole farside in late 2024. This payload will measure electric and magnetic fields on the surface, resulting from plasma/surface interactions, the lunar ionosphere, and photoelectron sheath effects. A second LuSEE payload will focus on exploratory low frequency (<50 MHz) radio astronomy measurements from the farside, in an effort to constrain cosmological models and provide best-yet low frequency foreground measurements.

The Compton Spectrometer and Imager (COSI) is an upcoming NASA Astrophysics Explorer satellite mission planned for launch in 2027. COSI observes in the 0.2-5 MeV gamma-ray energy band with a large (>25%-sky) field of view and daily all-sky coverage. COSI will study 511 keV electron-positron annihilation emission, nuclear lines, accreting black holes, and gamma-ray bursts. The germanium detectors have excellent energy resolution for making Galactic maps of 511 keV and nuclear liine emission, and the instrument will also make measurements of source polarization. In addition to Astrophysics, COSI has a Science Enhancement Option for solar science, and applications from people interested in Astrophysics or solar physics will be considered.

SSL is committed to filling these positions by attracting a pool of candidates with representation along all axes of diversity. SSL invites applicants from all backgrounds and life experiences. Applicants with hardware or instrumentation backgrounds in addition to experience publishing science results using observations from heliophysics or planetary projects are especially encouraged to apply.
