Five years ago yesterday — September 28, 2008 — a Falcon 1 rocket lifted off from Omelek island in the Kwajalein Atoll on its first successful demonstration flight.

Its payload, appropriately named Demosat, was a small pathfinder model made of aluminum that was also named “Ratsat.” The dummy spacecraft was bolted to the upper stage of the Falcon launcher, since it did not need to be placed in its own operational orbit.
This launch was the fourth attempt for SpaceX’s Falcon 1 vehicle, and the first one to successfully achieve orbit.
Twenty-five years ago today — September 19, 1988 — a Shavit rocket launched from Palmahim, Israel, in the Negev desert.

The Ofeq 1 (Horizon 1) spacecraft was a demonstration satellite and the first-ever launched by Israel from its own territory. Ofeq 1 operated until January 14, 1989, when it re-entered the atmosphere.
The successful launch “made Israel the eighth nation to launch a satellite on its own rocket.”
First, a little space history that I didn’t catch the first time around: 35 years ago this week, the Soviet Union sent two missions to Venus from the Baikonur Cosmodrome.
(Venera lander, or “descent craft.” Image from the National Space Science Data Center.)
The first of the two, Venera 11, consisted of a flyby platform and a lander (“descent craft”), and launched on September 9, 1978. The second, Venera 12, also consisted of a flyby platform and a lander, and launched on September 14th. Venera 12’s course got it to Venus four days ahead of Venera 11: the Venera 12 lander reached the surface of Venus on December 21, 1978, and the Venera 11 lander followed on Christmas day.
And to follow up on one of my earliest space history posts which noted the launch, 20 years ago today, of the Space Shuttle Discovery on mission STS-51: 5 years ago when I wrote that entry, I had no idea that a little over a year later I would meet one of the STS-51 astronauts, Frank L. Culbertson, Jr., at a NASA Industry-Education Forum. He was a very pleasant fellow, and well met.
Life can be weird and wonderful.
Five years ago today — September 6, 2008 — a Delta II rocket launched from Vandenberg AFB carrying a privately-owned remote sensing satellite.

Despite being privately owned and operated, one of GeoEye 1‘s main customers for its multi-spectral images is the Department of Defense. You can see a selection of GeoEye imagery in this gallery.
And on the same day that GeoEye 1 launched, the Chinese launched two environmental monitoring satellites, Huan Jing 1A and Huan Jing 1B, from the Taiyuan launch site on a Long March 2C rocket.
So, 5 years ago today was a good day for remote sensing!
I’m headed to Dragon Con in just a little while! But first …
Twenty-five years ago today — August 29, 1988 — a Soyuz rocket out of the Baikonur Cosmodrome carried the first Afghani citizen to fly in space.

The Soyuz TM-6 crew consisted of Russian cosmonauts Vladimir A. Lyakhov and Valeriy V. Polyakov, plus Afghani cosmonaut Abdul Ahad Mohmand. They spent a little over a week on the Mir space station before returning to earth.
In other space history, on this date 5 years ago another mission from the Baikonur Cosmodrome carried five German remote sensing satellites known as RapidEye-A through -E.
And speaking of remote sensing, congratulations to the Delta 4 launch team for successfully launching a National Reconnaissance Office satellite yesterday from my old stomping grounds, Vandenberg AFB!
The space history series is not dead yet! Here’s an item I missed the first go-round.
Ten years ago today — August 25, 2003 — a Delta 2 rocket launched from Cape Canaveral carrying the fourth of NASA’s “Great Observatories.”
(Artist’s conception of the Spitzer Space Telescope and the Earth’s orbital track. NASA image.)
Originally called the Space InfraRed Telescope Facility (SIRTF), it was renamed the Spitzer Space Telescope after astrophysicist Lyman Spitzer, Jr. (1914-1997), who “was the first person to propose the idea of placing a large telescope in space and was the driving force behind the development of the Hubble Space Telescope.”
The Spitzer orbiting observatory was the largest space-based infrared telescope yet launched. It trails behind the Earth in a heliocentric orbit.
More about the Spitzer mission is on this site.
I started my space history series of blog entries five years ago this month. I’ve never claimed that it was authoritative or museum-quality, or even particularly complete. But since I’ve concentrated on hitting events on their 5-year anniversaries, I’ve gotten to the point that I would be repeating entries.
(If you want museum-quality coverage of space history, you’re better off going to a museum. “Air and Space Museum” by Rob Crawley, on Flickr via Creative Commons.)
For instance, I posted about today’s anniversary of the Explorer 5 launch five years ago (although then I missed the event by one day). But I don’t see the point of repeating things I’ve already catalogued, so the nature of the series is going to have to change.
I plan to be more selective about entries from now on. I may pick out select incidents that are particularly important to me, or I may pick more contemporary items to highlight. I haven’t decided exactly how I want to proceed.
If you have any suggestions, I’d love to hear them! For instance, yesterday Guy Stewart suggested this story about Lunar Orbiter 1 taking the first picture of Earth from the Moon, which happened 47 years ago yesterday. Great story, Guy!
So, to sum up: Many thanks to everyone who has enjoyed the series, and let us know what you think we do from here on out!
Fifty-five years ago today — August. 17, 1958 — the U.S. made its first attempt at sending a spacecraft to the Moon.
(Pioneer 0. NASA image.)
Called alternately Pioneer 0 or Able 1, the satellite launched on a Thor-Able rocket out of Cape Canaveral. Not only was it the first attempt to reach the Moon, but it was “the first attempted lauch beyond Earth orbit by any country.”
Unfortunately, the first stage of the Thor exploded 77 seconds into the flight.
Failure was suspected to be due to a ruptured fuel or oxygen line or a faulty turbopump gearbox. Erratic telemetry signals were received from the payload and upper stages for 123 seconds after the explosion, and the upper stages were tracked to impact in the ocean.
Fifteen years ago today — August 13, 1998 — the Russians launched a crew to the Mir space station, and the U.S. launched a small science satellite.
(SCISAT-1. NASA image.)
Soyuz TM-28 launched from the Baikonur Cosmodrome with Gennadi I.Padalka, Sergei V.Avdeyev, and Yuri M.Baturin aboard. The trio docked with Mir two days later using manual controls because one of the two automatic systems had failed.
And on this date 10 years ago, the Canadian research satellite SCISAT 1 launched on a Pegasus XL rocket. The Pegasus was released over the Pacific Ocean from its L-1011 carrier plane, on a flight that originated out of Vandenberg AFB, and placed SCISAT in orbit to monitor atmospheric ozone and dust.
Thirty-five years ago today — August 12, 1978 — an Explorer-class spacecraft launched from Cape Canaveral on a Delta rocket.
(ISEE 3. NASA image.)
Originally named International Sun-Earth Explorer 3, the spacecraft was placed in a halo orbit around Lagrange point L-1 between the Earth and the Sun to study the magnetosphere. In 1982, after its L-1 observations, it was put through a series of maneuvers that took it through several encounters at the L-2 Lagrange point on the other side of Earth from the Sun.
After several passes through the Earth’s magnetotail, with gravity assists from lunar flybys in March, April, September and October of 1983, a final close lunar flyby (119.4 km above the moon’s surface) on December 22, 1983, ejected the spacecraft out of the Earth-Moon system and into a heliocentric orbit ahead of the Earth, on a trajectory intercepting that of Comet Giacobini-Zinner. At this time, the spacecraft was renamed International Cometary Explorer (ICE)…. [T]he spacecraft traversed the plasma tail of Comet Giacobini-Zinner on September 11, 1985, and made in situ measurements of particles, fields, and waves. It also transited between the Sun and Comet Halley in late March 1986, when other spacecraft (Giotto, Planet-A, MS-T5, VEGA) were also in the vicinity of Comet Halley on their early March comet rendezvous missions. ICE became the first spacecraft to directly investigate two comets.
In 1991, ICE was re-tasked for solar study. It operated until May 1997.
