The primary payload of the flight was the Atmospheric Laboratory for Applications and Science-2 (ATLAS-2), [5] :1 designed to collect data on the relationship between the Sun's energy output and Earth's middle atmosphere and how these factors affect the ozone layer. It included six instruments mounted on a Spacelab pallet in the cargo bay, with the seventh mounted on the wall of the bay in two Get Away Special (GAS) canisters. Atmospheric instruments included the Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment, the Millimeter Wave Atmospheric Sounder (MAS), and the Shuttle Solar Backscatter Ultraviolet (SSBUV/A) spectrometer (on the cargo bay wall). Solar science instruments were the solar spectrometry instrument SOLSPEC, [6] the Solar Ultraviolet Irradiance Monitor (SUSIM), and the Active Cavity Radiometer (ACR) and Solar Constant (SOLCON) experiments. [3]

ATLAS-2 is one element of NASA's Mission to Planet Earth program. All seven ATLAS-2 instruments first flew on ATLAS-1 during STS-45, and flew a third time in late 1994 on STS-66. [3]

On April 11, 1993, the crew used the remote manipulator arm (Canadarm) to deploy the Shuttle Point Autonomous Research Tool for Astronomy-201 (SPARTAN-201), a free-flying science instrument platform designed to study velocity and acceleration of the solar wind and observe the Sun's corona. Collected data was stored on tape for playback after return to Earth. SPARTAN-201 was retrieved on April 13, 1993. [3]

The crew also made numerous radio contacts to schools around the world using the Shuttle Amateur Radio Experiment (SAREX II), including brief radio contact with the Russian Mir space station, the first such contact between Space Shuttle and Mir using amateur radio equipment. [7] It was arguably the first time that the astronauts received amateur television video from the ham radio club station (W5RRR) at JSC. [3]

Other cargo bay payloads were the Solar Ultraviolet Experiment (SUVE), sponsored by Colorado Space Grant Consortium and located in a GetAway Special canister on the cargo bay wall. [3]

The middeck payloads were the Commercial Materials Dispersion Apparatus Instrumentation Technology Associates Experiment (CMIX), the Physiological and Anatomical Rodent Experiment (PARE), Space Tissue Loss (STL-1) experiment, the Cosmic Ray Effects and Activation Monitor (CREAM) experiment. the Hand-held, Earth-oriented, Real-time, Cooperative, User-friendly, Location-targeting and Environmental System (HERCULES), Radiation Monitoring Equipment (RME III), and an Air Force Maui Optical Site (AMOS) calibration test.

It was a highly publicized mission due to former Project Mercury astronaut and United States Senator John H. Glenn Jr.'s return to space for his second space flight. At age 77, Glenn became the oldest person to go into space, a record that remained unbroken for 23 years until 82-year-old Wally Funk flew on a suborbital flight on Blue Origin NS-16, launching on 20 July 2021, which in turn was broken by William Shatner at age 90 on 13 October 2021 and then by Ed Dwight on May 19 2024.

SOLAR was an ESA science observatory on the Columbus Laboratory, which is part of the International Space Station. SOLAR was launched with Columbus in February 2008 aboard STS-122. It was externally mounted to Columbus with the European Technology Exposure Facility (EuTEF). SOLAR has three main space science instruments: SOVIM, SOLSPEC and SOL-ACES.
