First Images of the Far Side

Fifty years ago today — October 4, 1959 — the first probe to return pictures of the far side (not the “dark side”) of the moon was launched. The Luna-3 flyby mission launched on a Vostok rocket from what is now the Baikonur Cosmodrome.

On the same day, the U.S. launched “Little Joe 6,” from Wallops Island, Virginia, to test the Mercury space capsule’s integrity and aerodynamics. The capsule reached 37 miles altitude and flew 79 miles downrange, and the mission was listed as “partially successful.”

The space race was on, a half century ago. Thinking about it makes me wonder if we have the national will to start running a space race again, with the Chinese and the Indians in the mix.

In the Old Days, Everyone Was a Rocket Scientist

Our first space history item is interesting, but not the main event: On October 1, 1949 — 60 years ago today — the Long Range Proving Ground was activated at Cape Canaveral, Florida. It became the Florida Missile Test Range, and eventually Patrick Air Force Base and the Kennedy Space Center.

But the event that elicited this post’s subject line happened 40 years ago today, in 1969, when the European satellite “ESRO-1B” was launched from Vandenberg AFB by a Scout rocket. The NASA press release for the launch is very interesting: it includes pages of background information that must have fed the interest and imagination of every would-be “steely-eyed missile man” in the general public.

I had to grab the press release from the Google cache because the NASA link was broken, and I’ll only copy a few paragraphs here:

September 28, 1969
RELEASE NO: 69-138
FOURTH ESRO SATELLITE TO BE LAUNCHED

A 176-pound satellite carrying eight experiments to study the polar ionosphere, the Northern Lights and related phenomena, is scheduled to be launched by a four-stage Scout rocket from the Western Test Range, Calif., no earlier than Oct. 1, 1969. Called ESRO-1B, the European designed and built satellite is the fourth in a cooperative program between the European Space Research Organization (ESRO) and the National Aeronautics and Space Administration (NASA). The program is carried out under terms of an agreement signed by the two organizations in December 1966, relating to providing ESRO with launching and associated services.

ESRO-1B is a duplicate or backup version of ESRO 1-Aurorae, a cooperative ESRO/NASA project, which was successfully launched into a highly elliptical near polar orbit by NASA on October 3, 1968, and is still operating. The same complement of eight experiments–a series of high-latitude particle detectors, auroral photometers, and Langrnuir probes–is being carried on board ESRO-1B. The experiments were provided by the Technical University of Denmark; Kiruna Geophysical Observatory, Sweden; the Radio and Space Research Station, Slough, England; the University of Oslo, Norway; the University of Bergen, Norway; the Norwegian Defense Research Establishment; and the University College, London, England.

The orbit planned for ESRO-1B is near-polar, inclined 86 degrees to the Equator, with an apogee of 435 kilometers (about 270 statute miles) and a perigee of 400 kilometers (about 248 statute miles). Orbit period will be 92 minutes. Scientific measurements made by the ESRO-1B will be concentrated over Northern Europe to enable correlation between ground-based polar ionosphere observations and measurements made simultaneously with sounding rockets launched from the ESRO launch site at Kiruna, Sweden.

Once injected into orbit, the ESRO-1B will be despun by means of a yo-yo system to about 1 RPM. Final stabilization will occur about 10 days after launch when the spacecraft locks onto the Earth’s magnetic field. This stabilization is achieved by means of a pair of magnets inside the satellite. To minimize oscillations, slender magnetic rods are also mounted inside the satellite.

And so on. On page 10 of the news release:

ESRO-IB FACT SHEET

Launch Window: 30-minute window which changes only slightly from day to day. The window opens at 3:29 p.m., (PDT), October 1, 1969.
Launch Site: Western Test Range, Lompoc, California, Pad SLC-5.
Launch Vehicle: Four-stage solid fuel Scout rocket.

Orbit:
Apogee: 435 km (about 270 statute miles)
Perigee: 400 km (about 248 statute miles)
Period: 92 minutes
Inclination: 86 degrees
Stabilization: Spacecraft is spin stabilized at about 148 rpm initially. Despun to one rpm by yo-yo mechanism and further despun by magnetic system which interacts with Earth’s magnetic field. Stabilization thereafter will be provided by a passive system consisting of two permanent magnets.

I find the inclusion of all the detail fascinating. But maybe that’s understandable, since I still am a would-be rocket scientist.

Space Radar Mission, 1994

Fifteen years ago today — September 30, 1994 — astronauts Michael A. Baker, Terrence W. Wilcutt, Thomas D. Jones, Steven L. Smith, Daniel W. Bursch, and Peter J. K. Wisoff launched from the Kennedy Space Center aboard Space Shuttle Endeavour on mission STS-68.


(STS-68 mission patch. NASA image.)

The mission carried the Space Radar Laboratory on its second flight, and imaged some of the same areas the SRL had imaged before.

Flying SRL during different seasons allowed comparison of changes between first and second flights. SRL-2 was activated on flight day one, and around-the-clock observations conducted by astronauts split into two teams. Besides repeating data takes over same locations as on first flight, unusual events also imaged, including erupting volcano in Russia and islands of Japan after earthquake there. Also tested was ability of SRL-2 imaging radars, Spaceborne Imaging Radar-C (SIR-C) and X-band Synthetic Aperture Radar (X-SAR), to discern difference between such human-induced phenomena as an oil spill in the ocean and naturally occurring film.

[BREAK, BREAK … BONUS SPACE HISTORY ITEM]

Normally I’d wait until next year to include this item, since I usually deal only in 5-year-multiple anniversaries, but this one is work-related.

I’ve been putting together aerospace history pages that focus on North Carolinians or people with connections to the state. It just so happens that four years ago today — September 30, 2005 — North Carolina astronaut William “Bill” McArthur launched on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, en route to taking command of International Space Station Expedition 12.

If you know any North Carolina teachers, direct them to the NC Aerospace Initiative’s Aerospace Education section, where we will link information on NC aerospace history that they can use in their classes.

A Space Anniversary for the Cold Warriors

Forty-five years ago today — September 24, 1964 — a Minuteman II intercontinental ballistic missile launched for the first time on a test flight from Cape Canaveral.

Hats off to all my missileer friends whose alert posture kept us safe during the Cold War and beyond — and deter nuclear aggression today. It was an honor to serve with you, even if my part was just to put together emergency action messages.

If you’re planning to visit South Dakota, you might consider adding the Minuteman Missile National Historical Site to your travel itinerary.

And 10 years ago today, in 1999, an Athena rocket launched the Ikonos-2 remote sensing satellite from Vandenberg AFB. Ikonos-2 was a non-military reconnaissance satellite, and the first of a “new generation” of high-resolution (1 meter) commercial imagers.

Apollo Test Launch, 45 Years Ago, and Lunar Mapping Today

Forty-five years ago today — September 18, 1964 — NASA launched a Saturn-1 booster from Cape Canaveral in mission SA-7, also known as Apollo “Boiler Plate 15.” The launch demonstrated the Launch Escape System (LES) for the first time.

Anything Apollo-related of course reminds me of the moon, but I’ll skip the shameless plug in favor of some exciting news about the current LRO mission:

After two months of checkout and calibration, NASA’s $504 million Lunar Reconnaissance Orbiter was maneuvered into a circular 31-mile-high mapping orbit Tuesday and scientists said Thursday the spacecraft’s instruments are delivering intriguing clues about the possible presence of water ice.

The exciting news and “intriguing clues” are indications that hydrogen deposits may exist not only in permanently-shadowed craters near the south pole, but elsewhere on the moon as well — perhaps buried under lunar soil. Whether they’re water, or ammonia, or methane, or something else is unclear, but there appears to be something there, and probably something useful. Read the whole Spaceflight Now report here.

50 Years Ago: World's First Lunar Probe

Fifty years ago today — September 12, 1959 — the Soviet Union launched the Luna-2 mission on a Vostok rocket from the Baikonur Cosmodrome. As noted, Luna-2 was the first probe to hit the moon: it impacted east of the Sea of Serenity (Mare Serenitatis).

One interesting element: Luna-2 carried a flag with the USSR’s hammer-and-sickle and a “September 1959” banner, making it the first mission to plant a flag on the moon.

Space History: Big Joe 1 and STS-64

Fifty years ago today — September 9, 1959 — the Mercury capsule test “Big Joe 1” launched from Cape Canaveral on an Atlas rocket. The booster operated nominally but its two outboard engines didn’t separate as planned, which left the payload 500 miles short of the predicted impact point; the overall test flight was still considered a success.

And fifteen years ago today, in 1994, Richard N. Richards, L. Blaine Hammond, Jr., Jerry M. Linenger, Susan J. Helms, Carl J. Meade, and Mark C. Lee launched from the Kennedy Space Center aboard Space Shuttle Discovery on mission STS-64.


(STS-64 mission patch, from NASA.)

The STS-64 mission was the first flight of the LIDAR (i.e., light detection and ranging, like radar but with lasers instead of radio) In-Space Technology Experiment, or “LITE.” Astronauts Lee and Meade accomplished the first untethered U.S. space walk in 10 years.

Space History: First Flight of Shuttle Discovery

Twenty-five years ago today — August 30, 1984 — the Space Shuttle Discovery launched from Kennedy Space Center on its maiden voyage.


(STS-41D launch. NASA image.)

Astronauts Henry W. Hartsfield, Jr., Michael L. Coats, Judith A. Resnik, Steven A. Hawley, Richard M. Mullane, and Charles D. Walker made up the crew of STS-41D, which was the first mission on which three separate satellites were deployed (SBS-D, Syncom IV-2, and Telstar 3-C).


(STS-41D mission patch. NASA image.)

The mission also carried an experimental solar wing with different types of solar cells that deployed to its full size (102 feet x 13 feet) several times to demonstrate large lightweight solar arrays — not unlike those currently on the International Space Station.

Nimbus-1 Weather Satellite: From Launch to STAR TREK

Forty-five years ago today — August 28, 1964 — the Nimbus-1 satellite, “the first in a series of second-generation meteorological research-and-development satellites,” launched from Vandenberg AFB on a Thor-Agena rocket.


(Nimbus Satellite Diagram, from www.ucsb.edu)

According to the National Space Science Data Center,

a short second-stage burn resulted in an unplanned eccentric orbit. Otherwise, the spacecraft and its experiments operated successfully until September 22, 1964. The solar paddles became locked in position, resulting in inadequate electrical power to continue operations.

Nevertheless, Nimbus-1 produced the first nighttime cloud-cover images from space and was followed by six more satellites in the Nimbus series.

So where does STAR TREK come in? According to Memory Alpha, a diagram of Nimbus-1 in its polar orbit was part of the data accessed by the Talosians when they scanned the Enterprise‘s data banks in the original pilot episode “The Cage.”

Science fact meets science fiction … I like it.

Three Nations, One Space Mission: AMPTE

Twenty-five years ago yesterday* — August 16, 1984 — a Delta rocket launched from Cape Canaveral carrying three different satellites known as the Active Magnetospheric Particle Tracer Explorers, or AMPTE. The three spacecraft were:

  • The U.S.-built Charge Composition Explorer
  • The Federal Republic of Germany’s Ion Release Module
  • And the mysteriously-named United Kingdom Satellite

One interesting feature of the mission were “active ion releases” by the German spacecraft:

two releases of clouds of lithium ions in the solar wind in front of the magnetosphere (September 11 and 20, 1984), barium “artificial comet” releases in the dawn and dusk magnetosheaths (December 27, 1984 and July 18, 1985), and two each releases of lithium and barium ions in the near magnetotail (March 21; April 11, 23; May 13, 1985)

to study the interactions between the cool injected material and the “hot, magnetized, rapidly flowing natural plasmas of the magnetosphere and solar wind.”

*Yes, I realize I’m late with this space history item. Sundays are busy days for me, and yesterday was busier than usual, so I didn’t get it done. If you’re curious about why Sundays are so busy for me, I refer you to this blog entry (and especially the associated free download).
