As we noted in a previous space history item, Surveyor-1 launched on May 30th. On this date, it became the first U.S. spacecraft to land on the Moon.

Surveyor 1’s first hour on the Moon was spent performing engineering tests. Photography sessions were then initiated throughout the remainder of the lunar day. The television system transmitted pictures of the spacecraft footpad and surrounding lunar terrain and surface materials. Some 10,338 photos were returned prior to nightfall on June 14.

Surveyor-1 and Mariner-9: to the Moon and Mars

Forty-five years ago today — May 30, 1966 — Surveyor-1 launched from Cape Canaveral on an Atlas-Centaur rocket.

Surveyor-1 was the first U.S. mission to make a soft landing on the Moon. The Surveyor program consisted of seven robotic lunar missions, designed to prove out capabilities and technologies for the Apollo lunar landings.

(As an aside: in my yet-unpubished novel, Walking on the Sea of Clouds, a team of colonists make their way south on an “ice run” and the main character takes a moment to reflect that only a slight detour would take them by the Surveyor landing site.)

In our other space history item for the day, 5 years later — on May 30, 1971 — the Mariner-9 mission to Mars launched, also on an Atlas-Centaur rocket from Cape Canaveral.

Taking advantage of favorable timing and a “direct ascent trajectory,” Mariner-9 sped past the Soviet Union’s Mars-2 and Mars-3 missions to arrive at Mars after only 167 days. On November 14, 1971, Mariner-9 become the first spacecraft in orbit around another planet.

Mars-3 Launches, to Follow Mars-2

Forty years ago today — May 28, 1971 — the USSR launched the Mars-3 probe.

With the identical Mars-2 mission already on its way, Mars-3 launched from the Baikonur Cosmodrome to follow it to the red planet. Once it arrived, on December 2, 1971, Mars-3 became the first craft to make a soft landing on the surface of Mars. However, perhaps because of a raging dust storm at the time of landing, it only operated for about 20 seconds before contact was lost.

Interestingly, the Mars-2 and Mars-3 missions were even more ambitious than just placing landers on the surface. Each lander also carried a small robot that was intended to “walk” on the Martian surface on a set of skis, taking radiation measurements along the way.

The Apollo Speech: 'Now it is time to take longer strides'

Fifty years ago today — May 25, 1961 — President John F. Kennedy spoke to Congress about several national priorities, and laid out the goal of what would become the Apollo program. He said, “Now it is time to take longer strides–time for a great new American enterprise–time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth.”


(President Kennedy speaking to Congress. Image from NASA’s history site.)

Speaking close on the heels of Yuri Gagarin’s orbital flight and Alan Shepard’s sub-orbital flight, Kennedy proposed an ambitious agenda in the final major section of his Special Message to the Congress on Urgent National Needs. With emphasis added, and a little commentary interspersed, here’s the text:

… if we are to win the battle that is now going on around the world between freedom and tyranny, the dramatic achievements in space which occurred in recent weeks should have made clear to us all, as did the Sputnik in 1957, the impact of this adventure on the minds of men everywhere, who are attempting to make a determination of which road they should take. Since early in my term, our efforts in space have been under review. With the advice of the Vice President, who is Chairman of the National Space Council, we have examined where we are strong and where we are not, where we may succeed and where we may not. Now it is time to take longer strides–time for a great new American enterprise–time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth.

The last sentence of that paragraph is speechwriting gold: a wonderful triplet that wraps up in the appropriately grand idea of the future of all mankind.

I believe we possess all the resources and talents necessary. But the facts of the matter are that we have never made the national decisions or marshalled the national resources required for such leadership. We have never specified long-range goals on an urgent time schedule, or managed our resources and our time so as to insure their fulfillment.

Recognizing the head start obtained by the Soviets with their large rocket engines, which gives them many months of leadtime, and recognizing the likelihood that they will exploit this lead for some time to come in still more impressive successes, we nevertheless are required to make new efforts on our own. For while we cannot guarantee that we shall one day be first, we can guarantee that any failure to make this effort will make us last. We take an additional risk by making it in full view of the world, but as shown by the feat of astronaut Shepard, this very risk enhances our stature when we are successful. But this is not merely a race. Space is open to us now; and our eagerness to share its meaning is not governed by the efforts of others. We go into space because whatever mankind must undertake, free men must fully share.

Another excellent phrase: “whatever mankind must undertake, free men must fully share.”

I therefore ask the Congress, above and beyond the increases I have earlier requested for space activities, to provide the funds which are needed to meet the following national goals:

First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations–explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon–if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.

Kennedy masterfully pulls the entire nation together into this grand enterprise. He will repeat the idea later, in a more direct way. First, some specifics …

Secondly, an additional 23 million dollars, together with 7 million dollars already available, will accelerate development of the Rover nuclear rocket. This gives promise of some day providing a means for even more exciting and ambitious exploration of space, perhaps beyond the moon, perhaps to the very end of the solar system itself.

Think how far out we might have space outposts if we had nuclear rockets. If you’re less optimistic, you might think about accidents with nuclear rockets; but still, nuclear propulsion would take us farther than chemical rockets ever will.

Third, an additional 50 million dollars will make the most of our present leadership, by accelerating the use of space satellites for world-wide communications.

Fourth, an additional 75 million dollars–of which 53 million dollars is for the Weather Bureau–will help give us at the earliest possible time a satellite system for world-wide weather observation.

Let it be clear–and this is a judgment which the Members of the Congress must finally make–let it be clear that I am asking the Congress and the country to accept a firm commitment to a new course of action, a course which will last for many years and carry very heavy costs: 531 million dollars in fiscal ’62–an estimated seven to nine billion dollars additional over the next five years. If we are to go only half way, or reduce our sights in the face of difficulty, in my judgment it would be better not to go at all.

No doubt, then as now, many people believed it would be better not to go at all. I, obviously, am not one of them. I like the way he lays it out as a challenge, though: in effect advising Congress to go “all in” long before poker became a popular spectator game.

Now this is a choice which this country must make, and I am confident that under the leadership of the Space Committees of the Congress, and the Appropriating Committees, that you will consider the matter carefully.

It is a most important decision that we make as a nation. But all of you have lived through the last four years and have seen the significance of space and the adventures in space, and no one can predict with certainty what the ultimate meaning will be of mastery of space.

I believe we should go to the moon. But I think every citizen of this country as well as the Members of the Congress should consider the matter carefully in making their judgment, to which we have given attention over many weeks and months, because it is a heavy burden, and there is no sense in agreeing or desiring that the United States take an affirmative position in outer space, unless we are prepared to do the work and bear the burdens to make it successful. If we are not, we should decide today and this year.

This decision demands a major national commitment of scientific and technical manpower, materiel and facilities, and the possibility of their diversion from other important activities where they are already thinly spread. It means a degree of dedication, organization and discipline which have not always characterized our research and development efforts. It means we cannot afford undue work stoppages, inflated costs of material or talent, wasteful interagency rivalries, or a high turnover of key personnel.

New objectives and new money cannot solve these problems. They could in fact, aggravate them further–unless every scientist, every engineer, every serviceman, every technician, contractor, and civil servant gives his personal pledge that this nation will move forward, with the full speed of freedom, in the exciting adventure of space.

Once again, Kennedy issues the call not only to Congress but to everyone who is likely to be involved in the effort. “This nation will move forward, with the full speed of freedom, in the exciting adventure of space.”

All in all, a brilliant speech — and the rest, as is so often said, is history.

The quest for the Moon had begun.

The Apollo Speech: Now It Is Time to Take Longer Strides

Fifty years ago today — May 25, 1961 — President John F. Kennedy spoke to the U.S. Congress and laid out the goal of the Apollo program.


(President Kennedy delivering the May 25th speech. Image from a NASA History Office web page.)

A year and a half later, at Rice University, Kennedy would make another important speech on the subject, but the May 1961 was the first. Fresh on the heels of Yuri Gagarin’s orbital flight and Alan Shepard’s suborbital flight, Kennedy said, “Now it is time to take longer strides–time for a great new American enterprise–time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth.”

Here’s the pertinent text of the Special Message to the Congress on Urgent National Needs, with emphasis added in a few places:

And the rest, as we have heard so often, is history: the quest for the Moon had begun.

Remembering ENDEAVOUR … plus, the First Martian Impact

While the Space Shuttle Endeavour is in orbit on its final flight, it seems fitting that we remember that 15 years ago today — May 19, 1996 — Endeavour launched from the Kennedy Space Center on another mission.


(The Inflatable Antenna Experiment, after deployment. NASA image.)

Mission STS-77 carried U.S. astronauts John H. Casper, Curtis L. Brown, Daniel W. Bursch, Mario Runco, Jr., and Andrew S. W. Thomas, and Canadian astronaut Marc Garneau. The astronauts conducted a variety of experiments, including deploying the free-flying Inflatable Antenna Experiment, which at its full size was as big as a tennis court.

Here’s wishing the best to the current crew of Endeavour as they carry out their mission to the International Space Station.

Also in today’s space history, 40 years ago the Mars-2 spacecraft launched from the Baikonur Cosmodrome. On its approach to Mars in November 1971, it released a lander that “entered the Martian atmosphere at roughly 6.0 km/s at a steeper angle than planned” and crashed: the first human-built article to reach the surface of Mars.

First U.K. Citizen in Space

Twenty years ago today — May 18, 1991 — the first British astronaut flew into orbit aboard a Soyuz launch vehicle.

Mission TM-12, crewed by cosmonauts Anatoli P. Artsebarsky and Sergei K. Krikalev and British astronaut Helen P. Sharman, launched from the Baikonur Cosmodrome en route to the Mir space station.

In addition to being the first Briton in space, Sharman was the first woman to visit Mir. She conducted biological experiments and contacted British schoolchildren via amateur radio during her week in space. She returned to earth with the crew of TM-11, the previous Mir occupants.

Satellite Radio Adds Roll to its Rock

Ten years ago today — May 8, 2001 — the Sea Launch team launched the XM-1 or “Roll” satellite from the Odyssey launch platform.


(XM-1 “Roll” launch from the Sea Launch platform. Image from www.sea-launch.com.)

In our “Satellite Radio in Space History” item, we noted the launch of XM-2, or “Rock” — so with this launch XM Radio officially had its Rock and Roll.

My time on the Pacific with Sea Launch came in the summer of 2002, and it’s still one of the coolest temporary duty assignments I ever had.

Freedom-7 — A Half-Century of U.S. Spaceflight

Fifty years ago today — May 5, 1961 — Alan B. Shepard, Jr., became the first U.S. astronaut launched into space.


(Freedom-7 launch. NASA image.)

Shepard had named his capsule Freedom-7, though the flight was also known as Mercury Redstone-3.* The mission had several objectives:

(1) familiarize man with a brief but complete space flight experience, including the lift-off, powered flight, weightless flight (approximately 5 minutes), re-entry, and landing phases of the flight;
(2) evaluate man’s ability to perform as a functional unit during space flight by demonstrating manual control of spacecraft attitude before, during, and after retrofire and by use of voice communications during flight;
(3) study man’s physiological reactions during space flight; and,
(4) recover the astronaut and spacecraft.

Shepard’s launch from the Eastern Space & Missile Center was only 23 days after Yuri Gagarin had become the first human in orbit. Shepard’s flight was suborbital, however, so the honor of being the first U.S. astronaut in orbit would eventually go to John Glenn.

A Space Platform for Laser Ranging

Thirty-five years ago today — May 4, 1976 — the LAGEOS-1 satellite launched on a Delta rocket from Vandenberg AFB.


(LAGEOS. NASA image.)

The Laser Geodynamics Satellite (LAGEOS) (also known as the Laser Geodetic Satellite) “was the first spacecraft dedicated exclusively to high-precision laser ranging and provided the first opportunity to acquire laser-ranging data that were not degraded by errors originating in the target satellite.”

The spacecraft itself was simple: a sphere covered with 426 “cube corner reflectors” or retroreflectors which return light directly to its source no matter the incident angle. According to this page, LAGEOS-1 also carried a small plaque designed by Carl Sagan:

The plaque is 4 inches by 7 inches (10 cm by 18 cm) stainless steel plate. The spacecraft carries two identical copies included in its interior. In its upper center it displays the simplest counting scheme, binary arithmetic. The numbers one to ten in binary notation are shown. At upper right is a schematic drawing of the Earth in orbit around the Sun, and an arrow indicating direction of motion. The arrowhead points to the right, the convention adopted for indicating the future. All arrows accompanying numbers are “arrows of time”. Under the Earth’s orbit is the binary number one, denoting the period of time used on the plaque — one revolution of the Earth, or one year. The remainder of the LAGEOS plaque consists of three maps of the Earth’s surface. The first map denotes the Earth 268 million years in the past. All the continents are shown together in one mass. The close fit of South America into West Africa was one of the first hints that continental drift actually occurs. The middle map represents the zero point in time for the other two maps. It displays the present configuration of the planets. The final map shows the Earth’s surface 8.4 million years from now — very roughly the estimated lifetime of the LAGEOS. Many important changes in the Earth’s surface are shown, including the drift of California out into the Pacific Ocean. Whoever comes upon the LAGEOS plaque needs only compare a current map of the Earth’s geography with that in the lower two maps to calculate roughly the difference between his time and ours.

Put it on your calendar: let’s meet up with LAGEOS-1 8 million years from now and see how accurate Sagan’s continental drift picture is.
