A few hours ago a Soyuz rocket was launched from the Kourou base, in French Guiana. After about 23 minutes the Cosmo-SkyMed Second Generation satellite successfully separated from the rocket’s Fregat last stage. About 85 minutes after the launch, the CHEOPS space telescope successfully separated from the rocket’s Fregat last stage.
The COSMO-SkyMed Second Generation satellite is the first of a constellation of two satellites that aims to replace the first generation’s four satellites. It’s a system of radar satellites for the territory observation, the result of a collaboration between the Italian Space Agency and the Italian Ministry of Defense.
The purpose of ESA’s CHEOPS (Characterizing ExOPlanets Satellite) space telescope is to conduct follow-up study of exoplanets using the transit method, which means observing the ones that pass in front of their star.
A little while ago 60 satellites of the Starlink constellation were launched on a Falcon 9 rocket from Cape Canaveral. After about an hour they were successfully deployed into their orbit at an altitude of about 280 kilometers all together and then started slowly disperse. This is SpaceX’s second mission to put the Starlink constellation into orbit to provide a global Internet connection coverage.
A few hours ago the ICON (Interface Region Imaging Spectrograph) satellite was launched using a Pegasus XL rocket by Northrop Grumman brought to an altitude of about 11,900 meters by an L-1011 airplane, also by Northrop Grumman, modified for this purpose. After a little more than 11 minutes, ICON was brought into a low Earth orbit at an altitude of about 575 kilometers, where the solar panels regularly deployed and sent the first signals.
A few hours ago a Vega rocket was launched from the Kourou base, in French Guiana, to deploy the United Arab Emirates’ Falcon Eye 1 satellite. About two minutes after the launch, immediately after what was supposed to be the second stage’s ignition there was an anomaly that caused the mission’s failure. This is the first failure for the Vega rocket after 14 successes.
A few hours ago SpaceX launched its Falcon Heavy rocket from Cape Canaveral on a mission involving the launch of various satellites in low and medium Earth orbit. The most powerful rocket in business launched satellites on behalf of NASA, the US Air Force and other entities, incuding CubeSat-class nanosatellites built by students. The mission required four burns for the Falcon Heavy rocket’s upper stage to place them in the various orbits required. The mass of the payloads to be taken into orbit was relatively small – around 3,700 kg – but the second stage needed a lot of fuel to carry out all the maneuvers required in this mission, therefore the initial thrust of the Falcon Heavy was needed.
