Missions

TRACERS mission patch

TRACERS

TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites), consisting of two identical satellites that will orbit Earth in tandem (one following the other), will help answer long-standing questions key to understanding space weather, particularly how the Sun transfers energy, mass, and momentum to near-Earth space.

ICI-5bis

ICI-5bis will study plasma turbulence and irregularities in the auroral ionosphere as a contribution to the international Grand Challenge Initiative – MLT (Mesosphere-Lower Thermosphere). 

ACES II rocket launch

ACES-II

This mission launched two rockets into an aurora to measure the interaction between solar magnetic particles and the Earth’s magnetic field. The rockets were launched in Andøya, Norway in 2022.

Investigation of Cusp Irregularities-5

The ICI-5 mission launched on a NASA sounding rocket from a Norwegian launch site on Nov. 26, 2019. The mission investigated Earth's polar cusps.

ICI-4

Investigation of Cusp Irregularities-4

The combination of American electron clouds and Norwegian northern lights spells trouble for navigation and communication in the Northern regions. The ICI-4 mission helped provide knowledge to predict the weather in space.

Instrumentation Projects

Hybrid Fluxgate and Search Coil Magnetometer

CHIMERA Hybrid Magnetometer

This project involves designing and building a magnetic field detector, called a magnetometer, that can operate on a new generation of satellites that are as small as a loaf of bread.

Enhanced Polar Outflow Probe

The Enhanced Polar Outflow Probe (e‑POP) is a research payload on the CASSIOPE spacecraft that is collecting new data on space storms and associated plasma outflows from the Earth’s ionosphere.

CABOOM testing

CABOOM

CubeSat Articulated Boom Option Optimization in Microgravity

Booms are used to keep magnetic field instruments at a distance from the rocket or satellite. Booms are small and need to be tested in microgravity.

Testing Centers

The Department of Physics and Astronomy offers trained support and operational staff­ able to develop fixturing, integration, and test plans to meet your project needs.

Services include wide temperature range vacuum testing, vibration testing, mass testing, thermal testing, and EMI/EMC Testing.

magnetic furnace

Magnetic Furnace

This furnace is used to manufacture a critical space-instrument component called a ring core, which is central to the functioning of a fluxgate magnetometer, an instrument used for measuring low-frequency magnetic fields.

Aurora from ACES II mission

Study discovers electromagnetic waves can make the northern lights glow brighter

A study from University of Iowa researchers reveals that the aurora borealis — the northern lights — appear brighter when electromagnetic waves in space interact with particles inside the aurora. Connor Feltman, a postdoctoral researcher in the Department of Physics and Astronomy at Iowa, examined data from two rockets that were launched into the aurora from Andøya, Norway, in 2022, an Iowa-led experiment known as the ACES-II mission.

NASA Launches Mission to Study Earth’s Magnetic Shield

NASA’s newest mission, TRACERS, soon will begin studying how Earth’s magnetic shield protects our planet from the effects of space weather. Short for Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, the twin TRACERS spacecraft lifted off at 11:13 a.m. PDT (2:13 p.m. EDT) on Wednesday, July 23, 2025, aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
