Comments Off on Triple Play for Shuttle DISCOVERY

Twenty-five years ago today — June 17, 1985 — the Space Shuttle Discovery launched from the Kennedy Space Center on mission STS-51G. U.S. astronauts Daniel C. Brandenstein, John O. Creighton, Shannon W. Lucid, John M. Fabian, and Steven R. Nagel were joined by French astronaut Patrick Baudry and the first Arab astronaut, Sultan Al-Saud of Saudi Arabia.

The STS-51G crew’s “triple play” involved launching three separate communications satellites during this one mission. They deployed the Mexican satellite Morelos-A on the 17th, the aptly-named Arabsat-IB satellite on the 18th, and finally Telstar-3D on the 19th.

The crew also released the SPARTAN-1 (Shuttle Pointed Autonomous Research Tool for Astronomy) on the 20th. Its X-ray instruments made observations of the center of the Milky Way, as well as of the Perseus cluster of galaxies. The crew retrieved SPARTAN-1 from orbit on the 24th, just prior to their return to Earth.

Comments Off on Venera-9 and -10, Twin Missions to Venus

Thirty-five years ago today — June 8, 1975 — the Soviet Union launched the Venera-9 mission to Venus. Venera-9 was the first mission to successfully return an image of the surface of Venus; specifically, the rocky terrain in the immediate vicinity of the lander.


(Photographs of the surface of Venus: top, from Venera-9, and bottom from Venera-10. From http://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-venus.html.)

A Proton rocket out of the Baikonur Cosmodrome sent the Venera-9 probe on its way. Its sister ship Venera-10 launched six days later, on June 14th. Each carried an orbiter section and a lander.

The Venera-9 lander descended successfully to the surface on October 22, 1975, and operated for nearly an hour before the heat (485 degrees Celsius) and pressure (90 atmospheres) destroyed it. The Venera-10 lander followed its sister to the surface on October 25, 1975, and landed over 2000 km away from the Venera-9 landing site. Venera-10 operated for over an hour before it, too, succumbed to the harsh Venusian environment.

If only they had found the tropical paradise envisioned by classic science fiction writers, instead of fields of heat-blasted rocks, we might have developed more motivation to get out there and explore….

First U.S. Spacewalk: Ed White Steps Out of Gemini-IV

Comments Off on First U.S. Spacewalk: Ed White Steps Out of Gemini-IV

Forty-five years ago today — June 3, 1965 — astronauts James A. McDivitt and Edward H. White launched from Cape Canaveral on a Titan-II rocket.


(Ed White on the first U.S. spacewalk. NASA image.)

A little over four hours into the flight, Ed White stepped out of the Gemini-IV capsule for the first-ever extravehicular activity (EVA) by a U.S. astronaut. His EVA lasted about 20 minutes and met all the mission objectives, though he and McDivitt had some trouble getting the hatch closed when he got back in the spacecraft.

Some great high-resolution images of the EVA are available at http://nssdc.gsfc.nasa.gov/planetary/gemini_4_eva.html.

McDivitt and White stayed in orbit for four days. One interesting side note to the mission was a famous UFO sighting by McDivitt while White was sleeping, of an object shaped “like a beer can with an arm sticking out”; it is likely he saw the second stage of their Titan-II. The claim is disputed by UFO enthusiasts, but the 1981 article by James Oberg linked above asks,

Is any conclusion possible after so many years, when the supporting evidence has been trashed and the eyewitness testimony has become fossilized by countless repetitions? The principal leg of the [UFO enthusiasts’] endorsement — that there weren’t any candidate objects within 1,000 miles — has been demolished by the recognized presence of the beer can-shaped Titan-II stage. McDivitt, more than a decade after the fact, refused to believe he could have misidentified that object — but both his degraded eyesight [because of issues in the Gemini capsule] and different viewing angle at the time of the sighting eliminate any reliability from that claim — and years of UFO research have taught us the surprising lesson that pilots are, in truth, among the poorest observers of UFOs because of their instinctive pattern of perceiving visual stimuli primarily in terms of threats to their own vehicles.

As to that last bit, about pilots perceiving objects as threats until proven otherwise … that’s probably a good thing. And possibly a lesson we could apply to other endeavors.

Mapping the Universe … in X-Rays

Comments Off on Mapping the Universe … in X-Rays

Twenty years ago today — June 1, 1990 — the US-UK-German Roentgen Satellite (ROSAT) launched from Cape Canaveral on a Delta II.


(X-ray image of Comet Hyakutake, taken by ROSAT’s High Resolution Imager. NASA image.)

True to its namesake, ROSAT was an X-ray observatory, designed to last 18 months and to conduct both a full survey of the sky and detailed observations of points of interest. The mission far exceeded expectations, as the spacecraft operated into 1999. ROSAT not only discovered X-ray emissions from comets, as seen in the image above, but specifically observed emissions from the impact of Comet Shoemaker-Levy on Jupiter.

Comments Off on Another Apollo Boilerplate Mission

Forty-five years ago today — May 25, 1965 — NASA launched Apollo boilerplate mission BP-26 from Cape Canaveral. This mission, like the previous mission in February, carried a satellite experiment.


(Launch of Pegasus-2, 3:35 a.m. EDT, May 25, 1965. NASA image.)

The Pegasus 2, like its predecessor, had large wings that detected impacts from micrometeoroids. The boilerplate Apollo command and service module acted as a protective shroud over the Pegasus experiment during launch.

Infrared Space Surveillance, a Half Century Ago

Fifty years ago today — May 24, 1960 — the Midas-2 spacecraft launched from Cape Canaveral on an Atlas booster.


(The “launch cover” for Midas-2. Click to enlarge. Image from http://rammb.cira.colostate.edu/dev/hillger/military-wx.htm. Note the price of the postage.)

Midas-2 was the first satellite to carry an experimental IR surveillance payload into orbit. (The Midas-1 launch attempt in February 1960 failed because of a problem with the booster.)

The Air Force’s “Missile Defense Alarm System” proceeded through a series of launches to test gradually more powerful detectors, but did not produce workable missile warning satellite coverage. However, the technical lessons from Midas launches were applied to the Defense Support Program series of missile warning spacecraft: the very same DSP satellites that provide launch detection today.

Spektr: Demilitarized Space Station Zone

Comments Off on Spektr: Demilitarized Space Station Zone

Fifteen years ago today — May 20, 1995 — the Russian Spektr (“spectrum”) module launched from the Baikonur Cosmodrome on a Proton-K rocket.


(Mir space station, photographed from STS-81. The Spektr module is in the upper right, with the two straight and two angled solar arrays. NASA image.)

Spektr was originally designed as a military outpost for surveillance and anti-missile experiments. With the collapse of the Soviet Union, the module was grounded until U.S.-Russian cooperative missions began in the mid-90s. The Russians removed their military hardware, refurbished the module, and installed additional solar panels and several U.S. experiment packages, in what might be thought of as the space age equivalent of beating a sword into a plowshare.

Spektr was mated to the Mir space station and served as an experimental laboratory and crew quarters for U.S. astronauts until it was damaged by a Progress resupply ship in 1997. Mir residents closed off the damaged module and eventually succeeded in routing power cables from its solar arrays into the interior of the station. Because of an air leak that was never located, however, the Spektr module could not be occupied again.

ATLANTIS at the Space Station, a Decade Ago

Comments Off on ATLANTIS at the Space Station, a Decade Ago

Ten years ago today — May 19, 2000 — the Space Shuttle Atlantis launched from the Kennedy Space Center on mission STS-101.


(Launch of STS-101. NASA image.)

Astronauts James D. Halsell, Jr., Scott J. Horowitz, Mary Ellen Weber, Jeffrey N. Williams, James S. Voss, and Susan J. Helms, along with cosmonaut Yuri V. Usachev, carried the SPACEHAB module into orbit and took part in International Space Station Assembly Flight ISS-2A.2a. They installed new equipment, delivered a ton of supplies, and made repairs to the station.

And today, of course, Atlantis is taking part in another space station mission at this very moment: installing equipment, delivering supplies, and making repairs. Its current mission also happens to be the last scheduled mission for Atlantis.

We look forward to a successful conclusion and a graceful retirement for shuttle Atlantis.

Sputnik-4, the Controversial Manned Spaceflight Pathfinder

Comments Off on Sputnik-4, the Controversial Manned Spaceflight Pathfinder

Fifty years ago today — May 15, 1960 — the Soviet Union launched Sputnik-4 from the Baikonur Cosmodrome.

The mission was designed to test the systems for launching men into space, but sources conflict about the design and operational details. It is clear that Sputnik-4 was launched by a modified SS-6 ‘Sapwood’ intercontinental ballistic missile, the same rocket that would become known (if it wasn’t already) as the Vostok. But spacecraft details vary.

Sputnik-4’s mass is listed on the National Space Science Data Center page (above) as 1477 kg, but this fascinating page, complete with detailed illustration, lists its mass as over 4500 kg. Some sources say the spacecraft carried a pressurized cabin in which sat an instrumented mannequin, others that it only carried a mock-up of the manned cabin.

The sources agree that the orbiting spacecraft malfunctioned when its retro rockets fired while the vehicle was oriented incorrectly. Instead of descending into the Earth’s atmosphere, it was actually boosted into a higher orbit. The effect of the malfunction became the subject of some controversy, as the spacecraft did not re-enter the atmosphere where it was supposed to. It is said to have de-orbited in October 1965, but this Wikipedia page mentions that debris from the spacecraft impacted in Manitowoc, Wisconsin in September 1962.

But the biggest controversy about this launch is the theory that it contained a living person rather than a mannequin or mock-up. Radio calls were apparently overheard between the spacecraft and the ground that had the character of distress calls, but they were attributed to taped transmissions meant to test the communications equipment.

This final controversy also includes an unlikely witness: author Robert A. Heinlein, the science fiction Grand Master.

This Wikipedia page about the so-called ‘lost cosmonauts’ reminded me that Heinlein had been touring the Soviet Union in the same timeframe as this launch (and of Francis Gary Powers’s crash in his U-2). Of course I pulled my copy of Expanded Universe down off the shelf to find this tidbit in the article “‘Pravda’ Means ‘Truth'”:

I am sure of this: At noon on May 15 a group of Red Army cadets were unanimously positive that the rocket was manned. That pravda did not change until later that afternoon.

You must decide on your own, of course, if you believe the official version.

Comments Off on Challenger Launches with Spacelab, and a Titan-IV Farewell

Twenty-five years ago yesterday* — April 29, 1985 — the Space Shuttle Challenger lifted off from Kennedy Space Center on mission STS-51B.


(STS-51B launch. NASA image.)

Astronauts Robert F. Overmyer, Frederick D. Gregory, Don L. Lind, Norman E. Thagard, William E. Thornton, Lodewijk van den Berg and Taylor G. Wang launched the student-built Northern Utah Satellite (NUSAT-1) and spent a week in space with the European Space Agency’s Spacelab-3.

And on April 29, 2005 — 5 years ago yesterday — the last Titan-IV to be launched from Cape Canaveral Air Force Station blasted off with a classified National Reconnaissance Office satellite aboard. Titan rockets had been launching military and civil payloads for nearly five decades, and this launch left one final Titan-IV in the inventory, which launched from Vandenberg AFB in October 2005.
