Moscow, Jan 12 (AP/UNB) — Russia's space agency says its specialists are attempting to fix problems that have blocked control of an orbiting radio telescope.
The Spektr-R satellite is continuing to transmit signals, but scientists have been unable to control the satellite since Friday.
The satellite was launched in 2011 and has exceeded its initially expected useful life of about three years. It is used to study radio sources within and outside Earth's galaxy.
An official from Russian space agency Roscosmos, Alexander Bloshenko, said Saturday that another attempt to establish control of the satellite will take place Sunday.

Cape Canaveral, Jan 10 (AP/UNB) — The Hubble Space Telescope's premier camera has shut down because of a hardware problem.
NASA said the camera stopped working Tuesday. Hubble's three other science instruments are still working fine, with celestial observations continuing.
This third incarnation of the wide field camera was installed by spacewalking astronauts in 2009. The camera has backup electronics that could be called into action, if necessary, according to NASA.
The camera has captured stunning images of stars, galaxies stretching far back in time and assisted in deep sky surveys. It's also studied objects in our own solar system, discovering some of the tiny moons around Pluto, as well as a 14th moon around Neptune. It takes pictures in both visible and ultraviolet light, as well as near infrared.
Orbiting 350 miles (560 kilometers) above Earth, Hubble was launched in 1990 and visited by space shuttle astronauts, for repairs and upgrades, five times.
Last fall, Hubble stopped working altogether for three weeks because of a pointing problem. This is the first time the camera has acted up like this, said Cheryl Gundy, a spokeswoman with the Space Telescope Science Institute in Baltimore, which handle science operations for the telescope.
"NASA is trying to pull together the team to try to diagnose the issue," Gundy said Wednesday.
"We would like to have Hubble back up and working as quickly as possible, and NASA is making that happen," even with the partial government shutdown, she added.
Washington, Jan 10 (AP/UNB) — Too often people die of an opioid overdose because no one's around to notice they're in trouble. Now scientists are creating a smartphone app that beams sound waves to measure breathing — and summon help if it stops.
The app is still experimental. But in a novel test, the "Second Chance" app detected early signs of overdose in the critical minutes after people injected heroin or other illegal drugs, researchers reported Wednesday.
One question is whether most drug users would pull out their phone and switch on an app before shooting up. The University of Washington research team contends it could offer a much-needed tool for people who haven't yet found addiction treatment.
"They're not trying to kill themselves — they're addicted to these drugs. They have an incentive to be safe," said Shyamnath Gollakota, an engineering and computer science associate professor whose lab turns regular cellphones into temporary sonar devices.
But an emergency room physician who regularly cares for overdose patients wonders how many people really would try such a device.
"This is an innovative way to attack the problem," said Dr. Zachary Dezman of the University of Maryland School of Medicine, who wasn't involved in the research.
Still, "I don't know if many folks who use substances are going to have the forethought to prepare," he added.
More than 47,000 people in the U.S. died of opioid overdoses in 2017. The drugs suppress breathing but a medicine called naloxone often can save victims — if it reaches them in time. Usually, that means someone has to witness the collapse. Dr. Jacob Sunshine, a University of Washington anesthesiologist, notes that people have died with a relative in the next room unaware they were in trouble.
The research team settled on cellphones as potential overdose monitors because just about everyone owns one. They designed an app that measures how someone's chest rises and falls to see if they're slipping into the slow, shallow breaths of an overdose or stop breathing completely.
How? The software converts the phone's built-in speaker and microphone to send out inaudible sound waves and record how they bounce back. Analyzing the signals shows specific breathing patterns.
It won't work inside a pocket, and people would have to stay within 3 feet. The researchers are in the process of making the app capable of dialing for help if a possible overdose is detected.
They put the experimental gadget to the test at North America's first supervised injection site in Vancouver, British Columbia, where people are allowed to bring in illegal drugs and inject themselves under medical supervision in case of overdose. Study participants agreed to have doctoral student Rajalakshmi Nandakumar place the app-running cellphone nearby during their regularly monitored visit.
The software correctly identified breathing problems that could signal an overdose — seven or fewer breaths a minute, or pauses in breathing — 90 percent of the time, the researchers found. Most were near-misses; two of the 94 study participants had to be resuscitated.
For a bigger test, the researchers next turned to people who don't abuse drugs but were about to receive anesthesia for elective surgery. Rendering someone unconscious for an operation mimics how an overdose shuts down breathing.
Measuring 30 seconds of slowed or absent breathing as those patients went under, the app correctly predicted 19 of 20 simulated overdoses, the researchers reported. The one missed case was a patient breathing slightly faster than the app's cutoff.
The findings were reported in the journal Science Translational Medicine. The researchers have patented the invention and plan to seek Food and Drug Administration approval.
