NASA Chooses SpaceX for Space Weather SmallSat Mission
In an exciting development, NASA has selected SpaceX to launch a pair of small satellites designed to investigate space.
Weather as part of an amazing rideshare mission scheduled for 2025. The mission, called Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS), involves two small satellites to study space weather and our planet’s magnetosphere from a low Earth orbit.
These smallsats were chosen by NASA in 2019 for its heliophysics Small Explorer (SMEX) program, with a budget of at most $115 million. Originally, TRACERS was planned to launch alongside another SMEX mission called the Polarimeter to Unify the Corona and Heliosphere (PUNCH).
However, things took an interesting turn in August 2022 when NASA decided to have a PUNCH ride aboard the same Falcon 9 rocket. Forgive me for the difficult terms. These terms go like that: the Spectro-Photometer especially for the History of the Universe, Epoch of Re-ionization for Ices Explorer (SPHEREx) in 2025.
While NASA’s announcement didn’t specify the launch details, NASA spokesperson Leejay Lockhart revealed that TRACERS will serve as the primary payload for a rideshare mission, taking it to a sun-synchronous orbit, and this journey is expected to commence no earlier than April 2025.
It’s worth knowing that the exact value of the task order was not disclosed. Still, we know that NASA added $3.593 million to SpaceX’s VADR (Venture Class Acquisition of Dedicated and Rideshare) contract on September 26.
However, this addition was not explicitly tied to the TRACERS task order. Once these two small spacecraft are placed into sun-synchronous orbit, they will continue on an exciting mission.
They will conduct repeated crossings of Earth’s polar cusp within the magnetosphere. This region is where magnetic field lines converge towards the north and south poles. The satellites will closely observe a fascinating phenomenon known as magnetic reconnection, which occurs when the solar wind interacts with our planet’s magnetosphere.
Heading this captivating mission is David Miles from the University of Iowa, who took on the role of principal investigator after the unfortunate passing of Craig Kletzing, also from the University of Iowa. Millennium Space Systems are expertly handling the construction of these spacecraft.
This upcoming launch promises to expand our understanding of space weather and its impact on Earth’s magnetosphere. It offers a glimpse into the dynamic interactions between our planet and the solar wind. The mysteries of space continue to unfold, and missions like TRACERS take us one step closer to unraveling them.
