Unfavorable weather conditions at KSC delayed the landing on Tuesday June 30 and Wednesday June 31, 1993. Low clouds and the possibility of rain showers in the vicinity of the Shuttle landing facility prevented Endeavour's landing. Endeavour burned 330 lbs more hypergolic propellant during reentry prompting an increase in orbiter redline fuel reserves for all future missions. Landing occurred July 1, 1993, 8:52 a.m. EDT. On KSC Runway 33. Payload Weight down: 28,925lbs. Orbiter Landing Weight: 244,400 lbs.
During the course of the eight-day flight, the astronauts successfully conducted scores of biomedical and materials sciences experiments inside the pressurized Spacehab module. Two astronauts particpated in a spacewalk and the European Retrievable Carrier (EURECA) was retrieved by the crew and stowed inside Endeavour's payload bay. EURECA was deployed from the Shuttle Atlantis in the summer of 1992 and contains several experiments to study the longterm efects of exposure to microgravity.
An improperly installed electrical connector on Endeavour's Remote Manipulator System (RMS) arm (installed 180 degrees off its correct position) prevented Eureca from recharging its batteries with orbiter power. A flight rule was requiring antenna stowage was waived and EURECA was lowered into the payload bay without latching its antenna. Mission Specialists David Low and Jeff Wisoff safely secured EURECA's dual antennas against the science satellite during the spacewalk performed on Friday. David Low was mounted an foot restraint on the end of Endeavour's robotic arm while Mission Specialist Nancy Sherlock (who would later take the married name Nancy Currie) positioned the arm so Low could gently push the arms against EURECA's latch mechanisms. Payload controllers then drove the latches to secure each antenna. The five-hour , 50 minute spacewalk completed STS-57 mission's primary goal of retrieving the EURECA science satellite. Afterwards, Low and Wisoff completed maneuvers for an abbreviated extravehicular activity (EVA) Detailed Test Objective using the robot arm. Activities associated with each of the areas of investigation -- mass handling, mass fine alignment and high torque -- were completed with both EVA crewmen taking turns on the robot arm. Low and Wisoff wrapped up their spacewalk and returned to Endeavour's airlock shortly before 3 p.m. Central.
During the rest of the mission, the crew worked on experiments in the Spacehab module in the Shuttle's lower deck. These experiments included studying body posture, the spacecraft environment, crystal growth, metal alloys, wastewater recycling and the behavior of fluids. Among the experiments was an evaluation of maintenance equipment that may be used on Space Station Freedom. The diagnostic equipment portion of the Tools and Diagnostics System experiment was performed by Nancy Sherlock. Using electronics test instruments including an oscilloscope and electrical test meter, Sherlock conducted tests on a mock printed circuit board and communicated with ground controllers via computer messages on suggested repair procedures and their results.
In addition, Brian Duffy and Jeff Wisoff ran experiments in transferring fluids in weightlessness without creating bubbles in the fluid. The experiment, called the Fluid Acquisition and Resupply Experiment, or FARE, studied filters and processes that may lead to methods of refueling spacecraft in orbit and transfers water between two foot-diameter transparent tanks on Endeavour's middeck, engineers can evaluate how the fluids behave while the shuttle's steering jets are fired for small maneuvers. Janice Voss worked on the Liquid Encapsulated Melt Zone, or LEMZ, experiment which uses a process called floating zone crystal growth. The low-gravity conditions of space flight permit large crystals to be grown in space.
Ron Grabe, Brian Duffy and Janice Voss participated in the Neutral Body Position study. Flight surgeons have noted on previous flights that the body's basic posture changes while in microgravity. This postural change, sometimes called the "zero-g crouch," is in addition to the one- to two-inch lengthening of the spine during space missions. To better document this phenomenon over the duration of a space mission, still and video photography of crew members in a relaxed position are taken early and late in the mission. Researchers will include these findings in the specifications for design of future spacecraft to make work stations and living areas efficient and more comfortable for astronauts.
Nancy Sherlock stepped through the electronics procedures portion of the Human Factors Assessment this morning. She set up a work platform then hooked up a notebook computer and went through a simulated computer procedure for a space station propulsion system.
On 6/28/93, Nancy Sherlock performed an impromptu plumbing job on the Environmental Control Systems Flight Experiment, a study of wastewater purification equipment that may be used aboard future spacecraft. EFE uses a mixture of water and potassium idodide to simulate wastewater. The solution is pumped through a series of filters to purify it. During the flight, experimenters have seen a reduced flow of water through the device and opted to perform the maintenance procedure. Sherlock loosened a fitting on one water line inside the experiment, wrapped the loose fitting with an absorbent diaper, and, using a laptop computer onboard, turned a pump on the experiment into reverse for about 20 minutes in an attempt to flush out the clog. Sherlock then retightened the fitting and put the experiment back into normal operation for ground experimenters, who will now spend about an hour and a half watching it run to see if the clog has been cleared.
Manned six crew. Carried Spacehab 1; retrieved Eureca-1 spacecraft. Payloads: Spacehab 01, retrieval of European Retriev-able Carrier (EURECA) Satellite, Superfluid Helium On-Orbit Transfer (SHOOT), Consortium for Materials Development in Space Complex Autonomous Payload (CONCAP)-IV, Fluid Acquisition and Resupply Experiment (FARE), Shuttle Amateur Radio Experiment (SAREX) II, Air Force Maui Optical Site (AMOS), GAS bridge assembly with 12 getaway special payloads.
"I'll Be Home For Christmas" The mission was extended twice to wait for acceptable landing weather in Florida. On July 1st if the weather was acceptable it would land in Florida, otherwise it would be sent to California. So it wasn't a question of whether they would land that day but where. Of course after that many delays the crew may have wondered when they would finally make it home... Capcom Susan Helms played"I'll Be Home For Christmas". Given that it was July 1st they presumably did make it home in time.
