Russia successfully launches Spektr-RG carrying two X-ray space telescopes
Russia today successfully used its Proton rocket to launch Spektr-RG, carrying two X-ray space telescopes.
Spektr-RG was first conceived in the 1990s, but got shelved then because Russia did not have the money to launch it. The project got revived in 2005 when the Germans came on to build one of the two telescopes.
“We had an ambitious plan for the project which didn’t correspond to the power of the country of that moment,” [lead scientist Mikhail] Pavlinsky told Spaceflight Now. “We decided to restart it with a smaller version.”
The Russian and German space agencies signed an agreement in 2009 to jointly develop the Spektr-RG mission, but the project faced additional schedule delays due to technical problems and a decision to switch the observatory from a Zenit launcher to a Proton rocket.
Designers also changed Spektr-RG’s observing location from an orbit around Earth to a looping trajectory around the L2 Lagrange point.
Spektr-RG is the largest Russian astronomy satellite to launch since the Spektr-R radio observatory in 2011. Spektr-R stopped responding to commands from the ground in January after exceeding its planned five-year mission lifetime, and Russian officials declared the mission over in April.
Spektr-RG’s planned mission is set for seven years.
The leaders in the 2019 launch race:
9 China
8 SpaceX
8 Russia
5 Europe (Arianespace)
The U.S. continues to lead China in the national rankings 14 to 9.
