...liquid hydrogen is instantly converted to hydrogen gas, which then blasts out of a nozzle. The resulting thrust is two to three times as great as that generated in conventional rocket engines by the explosive mixture of hydrogen and oxygen. Much larger payloads could thus be lifted into orbit...

According to Harvey Tananbaum, associate director at CFA, the new telescope "will be able to take sharper pictures, detecting fainter, more distant sources." Also, AXAF will remain in orbit for 15 years, in contrast to current telescopes, which function for only a year...

The telescope has taken some surprisingly good shots, including images of a gas jet streaming from a newborn star and a huge storm on Saturn...
