A Brief History of the Congolese Space Program

In recent months, NASA has lamented the lack of minority students interested in majoring in science and engineering fields and has now partnered with the United Negro College Fund in order to encourage college-bound African-American students to consider a career in these under-represented disciplines. If astrobiology research seems like an insurmountable goal to some U.S. students, perhaps they’d be encouraged by the efforts of the dedicated group of workers and researchers that comprises the space program in the Democratic Republic of Congo. With limited resources and an even more limited cash supply, Congolese rocket enthusiasts have been launching Troposphere crafts with varying degrees of success since 2007.

The idea of actually attempting space travel from Congo didn’t originate there, but rather with a West German company called Orbital Transport und Raketn Aktiengesellschaft (OTRAG). Founded in Stuttgart in 1975, OTRAG had a corporate vision of “space trucking,” or a “throwaway” method of transporting communication and other peaceful satellites into orbit at bargain-basement prices. The company had one major hurdle to overcome, however—mainly the amended 1954 Treaty of Brussels, which prohibited the development and launching of missiles on German soil. OTRAG made an unusual (and controversial at the time) agreement with President Mobutu Sese Seko of the Republic of Zaire in 1978 for the 25-year rental of a plot of land approximately the size of Indiana to serve as “the private Cape Canaveral of Africa.” The location was chosen partially for its proximity to the equator, but the willingness of a national leader to agree to a long-term lease for a large parcel of land also played a major part in Zaire’s selection. OTRAG-1, consisting of four propulsion modules, a nose cone, and four fins, was launched from Zaire on May 18, 1977, and achieved an altitude of 12 miles before the four engines broke off and OTRAG-1 plummeted back to Earth.

The Iron Curtain Comes Down

Two years after OTRAG-1 launched, President Mobutu bowed to pressure from the Soviet Union (who’d gathered “intelligence” tracing OTRAG to World War II-era Nazi scientists and were convinced the company was a front for gathering military intelligence) and cut its ties with OTRAG.

The German company took their $150 million and moved to Libya for a time before going belly-up. Meanwhile, the space bug had bitten the country now known as the Democratic Republic of Congo. It bubbled under the surface for many years, particularly in the mind of Jean-Patrice Keka, who graduated from Kinshasa’s Institut Supérieur des Techniques Appliquées (ISTA) with a degree in engineering. Keka formed his own company, Développement Tous Azimuts (DTA), with an eye to eventually launching the first African satellite.

Small Company, Big Dreams

In 2005 DTA hired a small team of Congolese scientists and began a space program called “Troposphere.” Being a tiny, independent company, DTA couldn’t afford to pay the researchers a salary comparable to what they’d earn, say, teaching at a university, but the prospect of having their name attached to such a ground-breaking project lured Congo’s best and brightest. The company purchased some land in Menkao, a suburb of Kinshasa, and built a control center that included an automatic powering device, a telemetry system, a video monitoring system to control the rocket trajectory and a rocket launching pad. The purchase of the necessary technological components to equip the center put a serious strain on DTA’s limited finances, and as a result much of the Troposphere I rocket was built out of scrap material. The scheduled launch date of that craft was April 2007, but it was scratched due to “technical reasons.”

Try, Try Again

Despite the disappointment of Troposphere I, DTA persevered and successfully launched Troposphere II on July 10, 2007. The rocket reached an altitude of 1,014 meters (.63 miles) in 35 seconds. Troposphere III suffered the same fate as model number one, but Troposphere IV managed to fly 15 km (a little over nine miles) into the atmosphere in 47 seconds on July 10, 2008, hitting a top speed of Mach 2.7. The Minister of Higher Education, University and Scientific Research, was present at this launch and upon his recommendation, the Congolese government got involved with DTA’s space program and offered some financial support.

Rats!

Troposphere V was a two-stage rocket that launched on March 28, 2008. The $50,000 five-meter long craft was supposed to reach an altitude of 36 km (22 miles) in 95 seconds at Mach 3. This was also the first craft in the Congolese space program to have a passenger aboard—a rat that ultimately gave its life for science, since Troposphere V failed to launch vertically and crashed shortly after liftoff. Despite this latest setback, Jean-Patrice Keka and his team are hard at work on Troposphere VI. The Congolese government is also offering its support, as a full-fledged space program could result in unlimited employment opportunities in the form of companies needed to produce the necessary chemical, electronic and telecommunication components. Keka also envisions future involvement in the project on a Pan-African level, with students across the continent choosing to study the corollary scientific disciplines in order to work together to build a state-of-the art space center.

These Sparrows Have Been Singing the Same Songs for 1500 Years

Swamp sparrows are creatures of habit—so much so that they’ve been chirping out the same few tunes for more than 1500 years, Science magazine reports.

These findings, published in the journal Nature Communications, resulted from an analysis of the songs of 615 adult male swamp sparrows found in six different areas of the northeastern U.S. Researchers learned that young swamp sparrows pick up these songs from the adults around them and are able to mimic the notes with astounding accuracy.

Here’s what one of their songs sounds like:

“We were able to show that swamp sparrows very rarely make mistakes when they learn their songs, and they don't just learn songs at random; they pick up commoner songs rather than rarer songs,” Robert Lachlan, a biologist at London’s Queen Mary University and the study’s lead author, tells National Geographic.

Put differently, the birds don’t mimic every song their elders crank out. Instead, they memorize the ones they hear most often, and scientists say this form of “conformist bias” was previously thought to be a uniquely human behavior.

Using acoustic analysis software, researchers broke down each individual note of the sparrows’ songs—160 different syllables in total—and discovered that only 2 percent of sparrows deviated from the norm. They then used a statistical method to determine how the songs would have evolved over time. With recordings from 2009 and the 1970s, they were able to estimate that the oldest swamp sparrow songs date back 1537 years on average.

The swamp sparrow’s dedication to accuracy sets the species apart from other songbirds, according to researchers. “Among songbirds, it is clear that some species of birds learn precisely, such as swamp sparrows, while others rarely learn all parts of a demonstrator’s song precisely,” they write.

According to the Audubon Guide to North American Birds, swamp sparrows are similar to other sparrows, like the Lincoln’s sparrow, song sparrow, and chipping sparrow. They’re frequently found in marshes throughout the Northeast and Midwest, as well as much of Canada. They’re known for their piercing call notes and may respond to birders who make loud squeaking sounds in their habitat.
