Russia test-launched its Angara-A5 space rocket for the
first time from the Vostochny Cosmodrome in the Far East, successfully putting
a test load in low orbit as part of an effort to develop a new post-Soviet
launch vehicle.
Key takeaways:
●
The 42.7-metre Angara launch vehicle, capable of
carrying payloads bigger than 20 tonnes into orbit, is being developed to
replace Russia's Proton M as Russia's heavy-lift rocket.
