NASA has chosen SpaceX to launch the COSI mission into space in 2027. The mission involves a gamma-ray telescope that will study gamma-rays emitted by massive star explosions and the creation of new atomic nuclei. Scientists will use data from COSI to map where elements are forming in the Milky Way galaxy and gain insights into the annihilation of positrons. The telescope will also report the location of short gamma-ray bursts caused by merging neutron stars.
COSI will operate in a unique orbit over the equator to avoid radiation interference, and SpaceX’s Falcon 9 rocket will be used for the launch. The rocket will deliver COSI directly into its operational orbit and perform a plane change maneuver at the equator. This maneuver requires a significant amount of energy, similar to placing a heavier satellite in a higher orbit.
NASA awarded SpaceX a contract valued at $69 million for the launch, which is a 37 percent increase from a previous contract due to inflation. The Falcon 9 rocket was the only certified rocket capable of launching COSI into its equatorial orbit. In the future, NASA hopes to have more options for launch vehicles, such as United Launch Alliance’s Vulcan rocket and Blue Origin’s New Glenn launcher.
The COSI mission will provide valuable insights into the processes behind the creation and destruction of chemical elements in the universe. By studying gamma-rays emitted by cosmic events, scientists can deepen their understanding of supernova explosions, nucleosynthesis, and other phenomena. The data collected by COSI will contribute to ongoing research efforts to unravel the mysteries of our galaxy and beyond.
SpaceX’s involvement in launching the COSI mission highlights the company’s continued partnership with NASA in advancing space exploration. As technology continues to evolve, new opportunities for scientific discovery and innovation are on the horizon. The successful launch of COSI in 2027 will mark another milestone in our quest to explore the cosmos and unlock the secrets of the universe.
