A few hours ago, the Sentinel-1D satellite, part of the Copernicus / GMES, was launched from the Kourou spaceport, in French Guiana, atop an Ariane 6 rocket. After about 34 minutes, the satellite regularly separated from the rocket’s last stage and started sending signals. Its final orbit in low Earth orbit will be at an altitude of about 693 kilometers.
A few hours ago, NASA’s two TRACERS satellites were launched atop a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base. After about an hour and 40 minutes, they successfully separated from the rocket’s last stage to begin the maneuvers that will place them in a Sun-synchronous orbit at an altitude of 600 kilometers.
The two TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) twin satellites join other space missions aimed at studying the Sun and its interactions with the Earth. The PUNCH mission was launched on March 12, and on March 15, the three CubeSat-class nanosatellites of the EZIE (Electrojet Zeeman Imaging Explorer) mission were launched. EZIE’s goal is to study changes in electrical currents moving through the upper layers of Earth’s atmosphere in the polar regions.
A little while ago, the Biomass satellite was launched atop a Vega-C rocket from the Kourou base in French Guiana. After about 58 minutes, it successfully separated from the rocket’s last stage and set off on a course that will take it to its Sun-synchronous orbit at an altitude of 666 kilometres, where it will study the biomass of forests around the world. This work will help us better understand the global carbon cycle and forest ecosystems.
A few hours ago, the SPHEREx space telescope and the PUNCH satellites, two NASA astronomy missions, blasted off atop a SpaceX Falcon 9 rocket from the Vandenberg base. After about 42 minutes, SPHEREx successfully separated from the rocket’s last stage, and about 10 minutes later, the PUNCH satellites also separated, within about a minute. Both missions will operate from a Sun-synchronous orbit at an altitude of 700 kilometers for SPHEREx and 570 kilometers for PUNCH.
A few hours ago, the Nova-C Athena Moon lander blasted off atop a SpaceX Falcon 9 rocket from Kennedy Space Center on Intuitive Machines’ IM-2 mission. After about 48 minutes, it successfully separated from the rocket’s last stage and set off on a course to the Moon, where it’s scheduled to attempt a landing on March 6. About 3 minutes later, NASA’s small Lunar Trailblazer satellite also separated from the rocket’s second stage, but its course is very different from Athena’s, so it will not reach the Moon until June.
