A few hours ago, the Sentinel-3C, part of the GMES/Copernicus program, and the FLEX satellites were launched from the space center in French Guiana atop a Vega-C rocket. After approximately an hour, Sentinel-3C separated from the rocket’s final stage, the adapter known as Vespa. About 57 minutes later, FLEX also separated from Vespa. Their final orbit is sun-synchronous, meaning they will pass over a specific area of ​​Earth at the same local time, at an altitude of approximately 815 kilometers.

A little while ago, NASA’s Nancy Grace Roman Space Telescope was launched atop a SpaceX Falcon Heavy rocket from the Kennedy Space Center. After just over 31 minutes, it successfully separated from the rocket’s last stage and set course for the area known as L2 (Lagrange Point 2), where its scientific mission will begin.

Originally known as the Wide Field InfraRed Survey Telescope (WFIRST) and later named after astronomer Nancy Grace Roman, this space telescope had a complicated and unusual history. Various infrared astronomy projects seemed impossible to approve due to a lack of funding, but in 2012, the National Reconnaissance Office (NRO) donated two unused spy satellites to NASA, each equipped with a mirror the size of Hubble’s, which has a diameter of 2.4 meters. This allowed this project to get started.

A few hours ago, the Chinese Zhuque-3 Y2 rocket blasted off from the Dongfeng commercial area, carrying the Honghu-03 satellite. The second stage successfully reached orbit with payload separation, achieving a successful primary mission on this rocket’s second flight, the first to deploy a real satellite into orbit. A goal for LandSpace, the company that developed the rocket, was to land the first stage, which was successful on this second attempt.

It was the afternoon in the USA when SpaceX conducted a new flight test of its Super Heavy rocket and Starship prototypes, launched from its base in Boca Chica, Texas. This is the 13th test involving the entire system of Elon Musk’s company, which is supposed to revolutionize space travel with an unprecedented transport capacity and be totally reusable. They are advanced prototypes with the Super Heavy identified as Booster 20 and the Starship identified as Starship 40 or Ship40 or simply S40. It was the second test of the vehicles in their Block 3 version.

A few hours ago, the Long March 10B rocket performed its maiden flight, which started with its launch from the Wenchang launch site. The rocket’s first stage also performed a controlled landing on a sea platform, as part of the development of a reusable launch system. This is a significant achievement because it’s a rocket that will be used for China’s crewed Moon missions.
