6:45 p.m. Skylab settles into 5oiar Inertial Orbit (ATMSolar Array pointing continually at the sun. )

7:45 p.m. Guidance controller in Houston reports apparentprobletos in some of the: gyros controlling space-craft.

9:15 p.m. William C. Schneider, Skylab Program Manager,announces "The launch of Skylab 2 has been re-cycled for 5 days to Sunday, May 20, because ofthe incidents Which occurred during the Skylab 1

' deployment. "10:00 p.m. News Conference, KSC Newsroom:

OWS Solar Arrays are not fully deployed (OWSSolar Arrays putting out some power, however}.Launch slipped to 11 a. m., EDT, Sunday, May 2with a 10 minute window. Will spend time untilthen "developing a flight plan that will maximizescientific return. "

Electrical power cut in half by OWS Solar Arraymalfunction. Decision made to connect powerfrom command and service modules (for as longas cryogenics will last) to OWS. This will meana reduced mission, perhaps 17 to 21 days, andreduced amount of experiments. Orders issuedto increase cryogenic load (at I_C). No deeisi,_mat this time concerning which experiments willbe eliminated. Plans for the other 2 Skylab missions are in state of flux. Still have a problemwith one gyro.

May 15, 1973

1:50 a.m. Decision made to change the attitude of the space:-craft. Skylab control reports that the workshopis absorbing solar energy and heating up insideas well as on the skin. The plan called for shift-ing the spacecraft 90 degrees so that the MDA

_Lz'0 a.m. Above maneuver reported completed.7:._,3 a.m. Skylab returned to Solar Inertial Attitude.9:20 a.m. Change of Shift Briefing from Johnson Space

Center. Neil Hutchinson announced tempera-tures on the OWS skin were about 180 degrees F.Temperatures inside about 100 degrees F.Changes in spacecraft attitude will continue tornaintain the lowest temperatures possible.

9:33 a.m. Astronauts departed skid strip for Houston fromKSC_

3:00 p.m. Status Briefing from Kmmedy Space Centerwith William C. Schneider, All centers work-ing on plans to perhaps construct and install a"thermal Shield" that will reflect the sun, thuscooling the workshop.

5:20 p.m. Currently the food appears to be all right, al-though some of the film may be fogged.A decision whether to launch on Sund_y will bemade Saturday afternoon.The doeto.rs at Johnsor_ Space Center reportedthat the high temperatures can be epected toruin about 50% of the 62 drugs and medications.Some of the sleep medications, injectables forsevere allergies or shock, and 0iso some of theointments are affected.

9:50 p.m. Change ,._iShift Briefing from Johnson SpaceCenter with Donald R. Puddy, Flight Director.Crew quarters of OWS pressurized to its cor-rect pressure for the mission: 5.0 p. s.i.Spacecraft stable in a standard attitude controlsystem configuration.

Although one gyro was lost, the spacecraft cannow maintain its stable attitude.Outside temperatures on the side facing the shnare about 295 degrees F and about 90 degrees Fon the opposite side. Temperatures insidehave stabilized at about ]20 d_


21/117

May id, 1973 continued8:30 p.m. Attitude changes necessary to lower temperatures

on Skylab appear successful. Temperature read-ings have been dropping steadily, varying between55 degrees F and 108 degrees F.

9:20 p.m. Change of Shift Briefing, Johnson Space Centerwith Don Puddy, Flight Director. Changes in thespacecraft's attitude have continued, varying thepitch of the vehicle.

Workshop producing 26,000 to 28,000 watts.Inside temperatures hovering a't 109-110 degreesF.

May 17, 19738:00 a.m. Temperatures had been stable M1 night and re-

mained stable at 110 degrees F inside the labora-tory.

!0:00 a.m. Sky!ab Status Briefing at Johnson Space Centerwith George B. Hardy, Skyiab Program Ullice,MSFC.

Flight controllers have stabilized Skylab at anangle of about 50 degrees to the sun's rays whichkeeps the side of the workshop away from directsunlight.

Skylab will continue to orbit in this positiGn untilthe astronauts dock with it. Maintaining thisattitude keeps temperatures as Iow as possible.Temperatures aboard the spacecraft droppedduring the. night from 109 degrees F to 90 degreesF.

11:00 a.m. Rusty Schweickart and Dr. Joseph Kerwin, bothat Marshall Space Flight Center, practiced EVAprocedures needed in order to install a sun screenover the OWS from outside: the commar_d module.


22/117

M:*5, 17, 19"13 continuedAt Johnson Space Center, Pete Conrad studiedstationkeeping and formation flying techniquesiti the CSM simulator.Also at Houston, Paul Weitz practiced proceduresfor erecting a san shad using a standup EVAtechnique. Astronauts Dave Scott and 1RonaIdEvans assisted.

1 30 p.m. Skylab Status Briefing at Johnscn Spac e Centerwith John Disher, Deputy Skylab Program Director,Headquarters.

Launch of Skyiab 2 delayed to May 25, 1973, at9:02 a. m., EDT.After reaching Skylab, Conrad rill make a fly-around inspection, noting any debris that wouldhazard an EVA.

.... _o,-, c,_on, he ,r,_l_ be _b_,. to u:se ashepherd's hook-like device to remove debrisand attempt to extend the OWS solar panel near-est him.

Based on his fly-around inspection flight, controllerswii1 decide the best way to install a sun shield.Two methods for installing a sun shieId have beendeveloped (a primary metilod and a backup). Thecrew wiIi carry both shields up to Skylab.One attempt calls for extending a sun shade mounton a T-shaped pole from the EVA station at the Aused for retrieving film.The second approach requires an EVA from thecommand module, with the CSM maneuvering alonthe outside of the workshop, while pulling a shieldover the laboratory.

3:30 p.m. Scientists and engineers at JSC determined thatSkylab's food is still safe to eat although testscontinue on possible changes in calories or taste.

4:00 p.m. Activities concentrated on developing two morethermal shields:

(1) A parasol using an automatic umbrella-like mechanism that will be pushed outthrough the scientific airlock and spreadout over the workshop.

(2) An inflatable life-raft type also deployed

The astronauts continued practicing methods ofdeploying other thermal shields already developedNo decision yet on which method will definitely bused.

A tool has been selected for trying to free onesolar panel that is partially extended.

6:00 p.m. Change of Shift Briefing at Johnson Space Center,Neff B. Hutchinson, Flight Director; George tIardDirector of Engineering Development and Integration, MSFC.Mission directors and the crew still evaluatingadvantages of various sun shields.

The crew will be furnished with one primary andat least one back-up method o[ installing a heatshield.


26/117

May 21, 197310:15 a.m. Reported during Change of Shift Briefing atJohnson Space Center.

Temperatures dropped in the coolant systemsthat supply a coolant to the EVA suits and to theairlock module.

Changing the angle of the spacecraft to the s_m has been necessary in order to keep that system

from freezing.Plans to deploy a "sail-like" sun shield from astand-up EVA out of the CSM has been eliminated.

Currently, the two preferred procedures entail:(1) Deploying an "umbrella-tjpe" shield

through the scientific airlock,

(2) Deploying a "sail-like" shield throughthe ATM h_.*rh_

1:00 p.m. The astronauts continue rehearsing deploymenttechniques and reviewing revised flight schedulc,._.

5:30 p.m. Change of Shift Briefing at Johnson Space Center,Milton Windler, Flight Director; Craig Staresinich,Electrical General Instrumentation and FlightSupport Systems Engineer for the Skylab Workshop.Temperatures inside the workshop have increasedto 125 - 129 F, as a result of maneuvering Skylatoward the sun. The changes in pitch were neceesa:'vto warm the airloek module coolant systems thatare in danger of freezing.Although changes in pitch have raised temperaturesin the food storage area, flight controllers will cothe workshop again (by another shift in attitude) bfore the heat damages any supplies.

11:00 a.m. Crew participates in an underwater EVA deploy-ing the twin-pole solar sheild.Johnson Space Center Press Conference, John D.Disher, Deputy Director of Skylab Program OfficeNt:SA Headquarters.Mission directors have decided that the astronautswill carry two sun_hades up to Skylab: the parasollike devic:e and the |.wLn-Do!e shield.Depending on weight the crew may also carry athird device as a second back-up proceddre.Extended on a pole through the scientific airloek,the 22 ft. by 24 ft. parasol device opens over theworkshop like an umbrella.The "twin-pole" shield is a nylon, mylar, andaluminum "sail" mounted on the end of an alurninuframe. An astronaut wil! extend the 50 ' A-shaDedframe along the length of the workshop so that thsail will cover the crew quarters.
