Apollo 11 Flight Plan
Commemorating the 30th Anniversary of the Apollo 11 Moon Landing
The flight plan for Apollo 11 was a minute-by-minute time line of activities for the mission crew--Neil Armstrong, Mike Collins, and Edwin "Buzz" Aldrin--and Mission Control in Houston. The flight was launched July 16, 1969. Touchdown on the moon took place, as scheduled, on July 20, 102 hours, 47 minutes, and 11 seconds after launch from Cape Kennedy. The astronauts spent 21 hours and 36 minutes on the moon, and returned to Earth on July 24.
The flight plan below describes tasks to be done 102 to 103 hours into the flight. Immediately after landing, Armstrong and Aldrin reviewed their lunar contact checklist and reached a decision on "stay/no stay." Armstrong then reported to Houston: "The Eagle has landed."
Flight plans, officially known as "flight data files," for Apollo 8 to Apollo 17, and other records related to the Apollo program, are in the custody of NARA's Southwest Region in Fort Worth, Texas. (NARA Record Group 255)
Flight Plan for the 102nd Hour of the Apollo 11 Mission (Moon landing 102 hours, 47 minutes, 11 seconds after launch)

How to read the flight plan:
This page is one of 185 pages in the plan. Each page represents one hour of the Apollo 11 flight. (We have added the colors as a key)
CSM = Command Service Module
CMP = Command Module Pilot
This column lists tasks for CMP Mike Collins
2nd column
3rd and 4th columns
LM = Lunar Module
CDR = Commander of the Mission
LMP = Lunar Module Pilot
These columns list tasks for CDR Neil Armstrong and LMP Buzz Aldrin
5th column
MCC-H = Mission Control Center-Houston.
This column lists tasks for Mission Control. Back to Top

Why would we offer our flagship $300 print for only $195?
Man's First Step on the Moon
by Norman Rockwell
Because we don't have to buy expensive four-color print advertisements for you to see just how beautiful this piece is--a 1/3-page ad in Smithsonian Air & Space magazine, in which we've advertised in the past, goes for about $5,000. And because we want to reward early subscribers to our new magazine.
This offer--and the few hundred prints left out of the 1000 edition--won't last long. So don't miss this tremendous investment opportunity!
Investment, you say? Yes! Many Rockwell prints have appreciated faster than Internet stocks. One Norman Rockwell print appreciated 40,000 fold from its initial offering price.
Man's First Step on the Moon was published under the watchful eye of Norman Rockwell's son, who now manages his father's estate. The original painting is owned by the Smithsonian. What a great way to commemorate the thirtieth anniversary of Apollo 11's great American adventure.

Look what the Hubble Telescope has spotted: "A Minuet of Galaxies." Released by NASA September 2, 1999. The Hubble continues to pay dividends. Thank goodness Shuttle astronauts were able to repair it after an unpromising debut. Below is the NASA press release.
This troupe of four galaxies, known as Hickson Compact Group 87 (HCG 87), is performing an intricate dance orchestrated by the mutual gravitational forces acting between them. The dance is a slow, graceful minuet, occurring over a time span of hundreds of millions of years. 
The Wide Field and Planetary Camera 2 on NASA's Hubble Space Telescope (HST) provides a striking improvement in resolution over previous ground-based imaging. In particular, this image reveals complex details in the dust lanes of the group's largest galaxy member (HCG 87a), which is actually disk-shaped, but tilted so that we see it nearly edge-on. Both 87a and its elliptically shaped nearest neighbor (87b) have active galactic nuclei which are believed to harbor black holes that are consuming gas. A third group member, the nearby spiral galaxy 87c, may be undergoing a burst of active star formation. Gas flows within galaxies can be intensified by the gravitational tidal forces between interacting galaxies. So interactions can provide fresh fuel for both active nuclei and starburst phenomena. These three galaxies are so close to each other that gravitational forces disrupt their structure and alter their evolution.
From the analysis of its spectra, the small spiral near the center of the group could either be a fourth member or perhaps an unrelated background object.
The HST image was made by combining images taken in four different color filters in order to create a three-color picture. Regions of active star formation are blue (hot stars) and also pinkish if hot hydrogen gas is present. The complex dark bands across the large edge-on disk galaxy are due to interstellar dust silhouetted against the galaxy's background starlight. A faint tidal bridge of stars can be seen between the edge-on and elliptical galaxies.
HCG 87 was selected for Hubble imaging by members of the public who visited the Hubble Heritage website (http://heritage.stsci.edu) during the month of May and registered their votes. The HST exposures of the winning target were then acquired in July 1999 by the Hubble Heritage Team and guest astronomers Sally Hunsberger (Lowell Observatory, Flagstaff, Arizona) and Jane Charlton (Pennsylvania State University).
