Russia Launches Long-Delayed Deep Space Radio Telescope

PARIS — Russia's long-delayed Spektr-R radio telescope successfully launched July 18 aboard a Zenit rocket from the Baikonur Cosmodrome in Kazakhstan, the country's Federal Space Agency said.
There was no immediate word on the operational status of the new radio observatory beyond the fact that it was placed into the planned elliptical orbit that peaks nearly 207,000 miles (330,000 kilometers) above the Earth, and reaches a low of about 621 miles (1,000 km).
Featuring a giant 30-foot (10-meter) wide antenna, the Spektr-R observatory is part of the international Radioastron astronomy project.
"The aim of the mission is to use the space telescope to conduct interferometer observations in conjunction with the global ground radio telescope network in order to obtain images, coordinates, motions and evolution of angular structure of different radio emitting objects in the universe," Federal Space Agency officials said in a statement. "Scientists also expect to obtain more information about pulsars and interstellar plasma, black holes and neutron stars in the Milky Way."
Scientists from more than 20 nations, including the United States, are participating in the project, either through contributions of on-board hardware or access to the terrestrial antennas that, working with Spektr-R, will permit interferometry measurements during the observatory's planned five years of operations.

In recent years, however, observers have begun to make headway. Some have extracted the spectra of light passing through the atmospheres of exoplanets as they cross the face of their parent stars — the equivalent of measuring the colour of the firefly's wings as it flits through the searchlight beam. Others have blocked the light of the parent star so that they can see exoplanets in distant orbits and record their spectra directly.
In the past two years, astronomers have begun to record spectra from a new generation of custom-built instruments such as the Gemini Planet Imager on the 8.1-metre Gemini South telescope at the summit of Cerro Pachon in Chile. Exoplanet spectroscopy will be a priority for several spacecraft and ground-based telescopes that are now in development.

i dont think that we can send a prob but what we can do i think is get a beam with a code inside it then send it out to a satellite booster that when it gets the beam it splits it to loads of other beams with each having a cod and then the satellite booster sends the millons of beams all over the galaxy at a very high rate so if something is out there it will uderstand the code and send it back .
