Hours after the launch, however, there was concern by ground controllers that the satellite and two others aboard the rocket had failed to reach their orbit. Attempts to establish radio contact with them were unsuccessful.
The Gurwin-1 satellite, developed and built with the help of Jewish immigrants from the former Soviet Union, was a sign of changing times and growing cooperation between the two once-hostile nations.
It was launched Tuesday from Plesetsk, 900 kilometers north of Moscow, by a Start booster rocket, an offshoot of technologies used to build SS-25 nuclear missiles.
A Russian-Mexican communications satellite and a Russian EKA-2 satellite also went up on the rocket.
The five-stage rocket roared into the overcast sky in a burst of fire, but after the fourth section separated, contact was lost.
Yossi Shartiel, a satellite project organizer in Israel, told Israeli army radio that controllers so far had lost contact with the craft. "We are worried," he said.
The 48-kilogram Gurwin-1 was built by Technion students, new immigrants and industry experts who donated time and hardware.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
