All five astronauts and cosmo- nauts have trained extensively for every aspect of the joint ac- tivities - which, when they fi- nally reach space, may seem like just another simulation to them. The last of the joint experi- ments is one that can be per- formed only with two space- craft and is ideal for ASTP. Shortly after the two ships sep- arate, on the morning of July 19, Apollo will maneuver into a position blocking the sun from the view of Soyuz, in effect, creating a solar eclipse. THIS ALLOWS the Soyuz cos- monauts a perfect opportunity to take photographs of the solar corona - the thin circle of light surrounding the sun's disk - which is invisible to earth-bound astronomers. The pictures re- turned from this experiment may be the best corona shots ever acquired. After the artificial eclipse, Apollo and Soyuz will go their separate ways. Leonov and Ku- basov plan to remain in orbit for about two days, conducting a few experiments on their own, then return to earth near Bai- konur (unlike American space- craft, manned Soviet missions always return with a soft land- ing on solid ground, instead of the ocean. The descent is slowed by a single parachute and retro- rockets.) pace d Stafford, Slayton and Brand, on the other hand, have a more ambitious schedule and will stay up for five days after separa- tion. Many of their experiments are follow-ups to projects in the 1973-74 Skylab series. FOR EXAMPLE, one Apollo experiment will investigate the advantages of zero-gravity man- ufacturing. Scientists believe that the crystals used in elec- tronic devices can be made more perfect under weightless conditions, and that such crys- tals will greatly advance the technology associated with in- tegrated circuits. Finally, on July 24, the astro- nauts will eject the Service Mod- ule portion of the Apollo space- craft and return to the Pacific Ocean in what may be the last American "splashdown" ever - the next breed of spacecraft, the Space Shuttle, will land like an airplane, on wheels. Critics of the space program, who usually focus upon the econ- omic aspects of space flight, have latched onto a few other factors of the $254 million ASTP mission in their protest. Chief among them is Senator William Proxmire (D-Wis.), who fears for the astronauts' safety in light of past Soyuz re-entry fa- talities and docking problems. Proxmire claims the Central Intelligence Agency has deter- mined that the Soviet Union can- not handle two of their own spacecraft at once. Soyuz 18, carrying two cosmonauts, was launched into orbit in late May and will reportedly remain there throughout the joint mis- sion next week. etente THE SOVIETS, however, say two simultaneous flights will not overburden their facilities be- cause the vehicles will be handled from separate control centers. In an emergency, the Russians add, the spacecraft linked with Apollo will get their "priority" attention. American officials stress that the flight is much more than "a handshake in the sky," and jus- tify ASTP by its purely scientific experiments, numbering more than 20. The greatest benefits of ASTP, in fact, may come long after either vehicle returns to earth. Space officials in the United States, faced with ever-tighten- ing budgets as the public loses interest in NASA activities, hope the project will lead to joint ef- forts in long-term space sta- tions or, conceivably, an Amer- ican-Soviet flight to Mars near the end of the century. WHATEVER its results, ASTP has already served as a sym- bolic end to the fast-paced, ex- pensive "space race" which be- gan with a Sputnik satellite in 1957. Both countries seem eager to explore for the sake of sci- ence now, and they may well end up doing it together. Tomorrow: Profiles of the ASTP crew members On.

For her Ann Arbor concert debut next week, she'll sing se- lections from Broadway musicals and is featured with our Festival Chorus in excerpts from "Candide" by Leonard Bernstein, and "The King and I" by Richard Rodgers. Under Donald Bryant's direction, the Chorus of 100 singers presents a group of four American folk songs and four Negro spirituals, in special arrangements by Mr. Bryant. _IIVFksITY All tickets $3, general admission, unreserved seating; USICAL CIET0 at our Burton Tower office (ours listed below) or at the door; BURTON TOWER, Ann Arbor (Hill Aud. box office open at 7 p.m. preceding concert.)
