In a earlier speech to members of Parliament Thursday night, Mr. Gorbachev said that outer space was the ''common property of mankind'' and that ''what we need is Star Peace and not Star Wars.''

To this end, he called for creation of an international center to carry out research and development in space at the request of developing nations. He said he would welcome its establishment in India, which already has an extensive space program, with its own rockets and satellites.

As he has found repeatedly this week, Mr. Gorbachev's audience was highly receptive to his appeals. The Parliament members in the cavernous central hall of the 60-year-old building repeatedly applauded and pounded their desks in agreement.

Prime Minister Rajiv Gandhi had earlier repeated his own denunciations of ''Star Wars.'' On Tuesday, the day Mr. Gorbachev arrived, he hailed the Soviet leader as a ''crusader for peace.'' Many Public Ceremonies

Until Thursday, Mr. Gorbachev had confined his public remarks to generalities and had only indirectly referred to the United States. Instead, he has held long meetings with Mr. Gandhi and attended many public ceremonies, as has his wife, Raisa.

The meetings culminated in a series of agreements signed by the two leaders Thursday, including one calling for $1 billion in economic aid over the next several years for the construction of power plants and industrial modernization.

The new aid plan goes beyond a separate $700 million package signed after Mr. Gandhi visited the Soviet Union last year. Indian economists said the main advantage of the new package derived from its more favorable terms.
