Introducing Ethiopia’s just born Space research programme

High above the crowded streets of Addis Ababa, among fields where farmers lead oxen dragging wooden ploughs, sits Ethiopia’s space programme.              

Perched at the top of the 3200m-high Mount Entoto, two metal domes house telescopes, each a metre in diameter. In operation for only a few months, they have propelled Ethiopia into an elite club of African countries to have embarked on a space programme.

Its programme is aimed at giving the country a technological boost that will aid its already rapid development.

“Science is part of any development cycle,” says Abinet Ezra, spokesman for the Ethiopian Space Science Society. “Without science and technology nothing can be achieved.

“Our main priority is to inspire the young generation to be involved in science and technology.”

The society, funded by Ethiopian-Saudi business tycoon Mohammed Alamoudi, was set up in 2004 to promote astronomy. But its supporters have had a tough ride setting up the space programme.

For the past decade, a handful of enthusiasts - including Solomon Belay, director of the observatory and a professor of astrophysics - battled with the authorities to convince them that, in a country that is still one of the poorest in the world, where malnutrition is still a threat, the exploration of space is not a luxury. Ethiopian strongman Meles Zenawi, who died in 2012, considered them dreamers.

“People said we were crazy,” says Belay.

The R39-million space observatory is, above all, a symbol. The site at Entoto, often hidden by clouds during the rainy season and close to the lights of Addis Ababa, struggles to compete with the world’s major observatories, including the far larger Southern African Large Telescope in South Africa.

But Ethiopia has plans, including to build a far more powerful observatory in the northern mountains around Lalibela, far from city lights.

The government hopes to launch a national space agency - and to put an Ethiopian satellite in orbit within five years, for the monitoring of farmland and to boost communications.

“We are using space applications in everyday activities, for mobile phones, weather - space applications are fundamental,” says Kelali Adhana, the International Astronomical Union chief for East Africa, based in Ethiopia. “We cannot postpone it, otherwise we allow ourselves to live in poverty.”

At Ethiopia’s Institute of Technology, in the northern town of Mekelle, scientists plan to test the first Ethiopian rocket to go more than 30km, although that is still far from the 100km frontier beyond which the Earth’s atmosphere gives way to space proper.

Aboard the International Space Station this morning, Astronaut Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) successfully captured JAXA’s Kounotori 5 H-II Transfer Vehicle (HTV-5) at 6:28 a.m. EDT.

Yui commanded the station’s robotic arm, Canadarm2, to reach out and grapple the HTV-5, while NASA astronauts Kjell Lindgren provided assistance and Scott Kelly monitored HTV-5 systems. The HTV-5 launched aboard an H-IIB rocket at 7:50 a.m. Wednesday, Aug. 19, from the Tanegashima Space Center in southern Japan. Since then, the spacecraft has performed a series of engine burns to fine-tune its course for arrival at the station.

The HTV-5 is delivering more than 8,000 pounds of equipment, supplies and experiments in a pressurized cargo compartment. The unpressurized compartment will deliver the 1,400-pound CALorimetric Electron Telescope (CALET) investigation, an astrophysics mission that will search for signatures of dark matter and provide the highest energy direct measurements of the cosmic ray electron spectrum.

Below is a breathtaking image shared by Astronaut Scott Kelly of the HTV-5 and Canadarm2, which reached out and grappled the cargo spacecraft.

Space Launch System

Our Space Launch System (SLS) is an advanced launch vehicle for exploration beyond Earth’s orbit into deep space. SLS, the world’s most powerful rocket, will launch astronauts in our Orion spacecraft on missions to an asteroid and eventually to Mars!

A launch system required to carry humans faster and farther than ever before will need a powerful engine, aka the RS-25 engine. This engine makes a modern race car or jet engine look like a wind-up toy. With the ability to produce 512,000 pounds of trust, the RS-25 engine will produce 10% more thrust than the Saturn V rockets that launched astronauts on journeys to the moon!

Another consideration for using these engines for future spaceflight was that 16 of them already existed from the shuttle program. Using a high-performance engine that already existed gave us a considerable boost in developing its next rocket for space exploration.

Once ready, four RS-25 engines will power the core stage of our SLS into deep space and Mars.

Sea Level Rise

For thousands of years, sea level has remained relatively stable. But now, Earth’s seas are rising. Since the beginning of the 20th century, they have risen about eight inches, and more than two inches in the last 20 years alone!

As water warms, it expands and takes up more space. That means that when oceans warm, the sea level rises. This summer, we’ve been researching exactly how global warming has impacted Greenland’s ice sheet. Our ICESat-2 mission will use a laser to measure the height of the planet’s surface. Over time, we will be able to provide a record of elevation change, and estimate how much water has melted into the ocean from land ice change.

So how much ice are we actually losing? Great question, but the answer might shock you. In Greenland alone, 303 gigatons of ice was lost in 2014!

Since we know that ice is melting, we’re working to gain a better understanding of how much and how fast. We’re using everything from planes, probes and boats, to satellites and lasers to determine the impact of global warming on the Earth’s ice.

An Exo-What...?

Simply put, an exoplanet is a planet that orbits another star. That said, just because a planet orbits a star (like Earth) does not mean that it is automatically stable for life. The planet must be within the habitable zone, which is the area around a star in which water has the potential to be liquid…aka not so close that all the water would evaporate, and not too far away where all the water would freeze.

Recently, with the help of our Kepler spacecraft, scientists have discovered the most Earth-like exoplanet ever, Kepler-452b. Pretty cool! This chart shows 12 other exoplanet discoveries that are less than twice the size of Earth, and live in the habitable zone of their host star. Kepler-452b is special because all previous findings have orbited stars that are smaller and cooler than Earth’s.

You may be thinking, “Okay, so what? There’s an Earth-like planet that spins around a similar sized sun.” Well, Kepler-452b orbits its sun at nearly the same distance from its star as Earth does from our sun, which means that conditions on the plant could be similar to those here on Earth!

We can already guess your next question…”When are we going to Kepler-452b?!” Well, this planet is located in the constellation Cygnus which is 1,400 light-years away, so not anytime soon. However, our Kepler spacecraft continues to search for Earth-like exoplanets and gather important scientific information about them.

What’s Up for September?

Stargazing and looking up into the night sky is always a fun thing to do. This month, it will be especially exciting because there will be a total eclipse of a supermoon, plus the opportunity to see planets and the late-summer Milky Way!

What is a supermoon?

A supermoon is a new or full moon that occurs when it is at, or near its closest approach to Earth in a given orbit. There are usually 4 to 6 supermoons every year.

Observers can view the total eclipse on September 27, starting at 10:11 p.m. EDT until 11:23 p.m. This event will be visible in North and South America, as well as Europe and Africa. So make sure to mark your calendars!

This month, you will also be able to see the planets! Look for Mercury, Saturn, Pluto and Neptune in the evening sky. Uranus and Neptune at midnight, and Venus, Mars and Jupiter in the pre-dawn sky.

Finally, if you’re able to escape to a dark location, you might be able to see a great view of our Milky Way!

So, make sure to get outside this month and take a look at everything our night sky has to offer.

This is the most detailed map yet of our place in the universe

Say hello to Laniakea, our local galaxy supercluster.

The Laniakea Supercluster (Laniakea; also called Local Supercluster or Local SCl) is the galaxy supercluster that is home to the Milky Way, our galaxy, and therefore to the Solar System and the Earth.
