Spacewalkers install bird-tracking antenna

CAPE CANAVERAL, Fla.—Spacewalking cosmonauts set up an antenna for tracking birds on Earth and sent a series of tiny satellites flying from the International Space Station yesterday.

Russian Sergey Prokopyev used his gloved right hand to fling four research satellites into space.

The first mini satellite safely tumbled away as the space station soared 250 miles above Illinois.

More delay, cost for space telescope

CAPE CANAVERAL, Fla.—NASA's next-generation space telescope has been delayed yet again at a staggering cost of $1 million a day.

For the third time in less than a year, the space agency yesterday announced a lengthy postponement for the James Webb Space Telescope.

The observatory now will fly no earlier than 2021; until last fall, it was on the books for a 2018 launch.
