Historic NASA Asteroid Mission: Capsule Touches Down With Rock Sample From Bennu

September 25, 2023 

A NASA spacecraft carrying a sample of rock and dust from asteroid Bennu touched down safely in the Utah desert on Sunday, marking the end of a historic mission to study one of the most primitive objects in our solar system. The OSIRIS-REx spacecraft, which launched from Earth in 2016, arrived at Bennu in 2018 and spent two years orbiting and studying the asteroid. In October 2020, OSIRIS-REx extended a robotic arm and touched Bennu's surface for five seconds, collecting a sample of material.

The spacecraft then began a two-year journey back to Earth. On Sunday, September 25, 2023, OSIRIS-REx released a capsule containing the Bennu sample, which parachuted safely to the ground in the Utah Test and Training Range.The Bennu sample is the largest and most pristine asteroid sample ever returned to Earth. It will be studied by scientists around the world to learn more about the early history of our solar system and the potential for asteroids to harbor organic molecules or even life. OSIRIS-REx mission is a major milestone in space exploration and a testament to the ingenuity and dedication of NASA scientists and engineers. The following is a more detailed account of the mission and the science that it is expected to produce:



The OSIRIS-REx mission was designed to study asteroid Bennu and collect a sample of its surface material. Bennu is a near-Earth asteroid that is about 492 meters (1,614 feet) in diameter. It is thought to be a primitive asteroid, which means that it has not changed much since it formed billions of years ago. OSIRIS-REx launched from Earth in September 2016 and arrived at Bennu in December 2018. The spacecraft spent two years orbiting and studying Bennu. During this time, OSIRIS-REx mapped Bennu's surface, measured its temperature and gravity, and studied its composition.

In October 2020, OSIRIS-REx extended a robotic arm and touched Bennu's surface for five seconds, collecting a sample of material. The spacecraft then began a two-year journey back to Earth. On September 25, 2023, OSIRIS-REx released a capsule containing the Bennu sample, which parachuted safely to the ground in the Utah Test and Training Range.



Scientific Goals

The OSIRIS-REx mission has two main scientific goals:

  1. To study asteroid Bennu and learn more about its composition, formation, and evolution.
  2. To collect a sample of Bennu's surface material and return it to Earth for study.

Scientists are particularly interested in Bennu because it is a primitive asteroid. Primitive asteroids are thought to be the building blocks of the planets and moons in our solar system. By studying Bennu, scientists can learn more about the early history of our solar system and the formation of planets and moons.

The Bennu sample is also of great interest to scientists. It is the largest and most pristine asteroid sample ever returned to Earth. By studying the sample, scientists can learn more about the composition of asteroids and the potential for asteroids to harbor organic molecules or even life.

The OSIRIS-REx mission is a major milestone in space exploration. It is the first mission to return a sample of material from a primitive asteroid. The Bennu sample is expected to revolutionize our understanding of the early history of our solar system and the formation of planets and moons. The sample is also expected to shed light on the potential for asteroids to harbor organic molecules or even life. If organic molecules are found in the sample, it would suggest that asteroids could have played a role in the delivery of life to Earth. The OSIRIS-REx mission is a testament to the ingenuity and dedication of NASA scientists and engineers. It is a complex and ambitious mission that has the potential to change our understanding of the universe.

The OSIRIS-REx mission is a historic achievement that is sure to revolutionize our understanding of asteroids and the early history of our solar system. The Bennu sample is the most pristine asteroid sample ever returned to Earth, and it is expected to provide scientists with a wealth of new information. The OSIRIS-REx mission is also a testament to the ingenuity and dedication of NASA scientists and engineers. It is a complex and ambitious mission that has the potential to change our understanding of the universe.

Cameroon's Absentee President: The Challenges of Biya's Extended Rule

By Edwin -

Paul Biya, the President of Cameroon, has been in power since November 6, 1982, making him one of the longest-serving leaders in the world. At 92 years old, his continued candidacy for the 2025 presidential election raises significant concerns among the populace. His leadership has been characterized by a lack of visibility and engagement with the citizens, as he is often seen leaving the country rather than addressing domestic issues directly. Under Biya's administration, Cameroon faces numerous pressing challenges: Escalating Violence: The ongoing conflict in the North West and South West regions has not been effectively managed. The Anglophone crisis has led to widespread violence and instability, with many citizens feeling abandoned by their government.  President Biya as the leader has never visited these regions since the conflict started in 2016. Many have attributed these to his unwillingness to address the problems while others thinks his physical ability can not permit hi

Africa Awaits Mpox Vaccines Amidst Growing Outbreak

As the mpox outbreak continues to escalate across Africa, the continent is facing a critical shortage of vaccines necessary to combat the virus. The World Health Organization (WHO) has recently declared the situation a public health emergency of international concern, highlighting the urgency of the crisis. The Africa Centres for Disease Control and Prevention (Africa CDC) has estimated that while there are currently about 200,000 doses available, the continent requires at least 10 million doses to effectively manage the outbreak. The Democratic Republic of the Congo (DRC) has been particularly hard hit, reporting over 17,000 cases and more than 500 deaths this year alone. The DRC has called for international assistance, specifically requesting 3.5 million doses to address its immediate needs. Despite pledges from various countries, including the United States and Japan, the promised vaccines fall significantly short of what is required. Consequences of the Vaccine Shortage The lack of

Power Dynamics at Play: The Significance of the 2024 China-Africa Cooperation Summit

The 2024 Summit of the Forum on China-Africa Cooperation (FOCAC), scheduled to take place in Beijing from September 4 to 6, 2024, presents a significant opportunity for dialogue between Chinese and African leaders.  The summit will revolve around the theme of  "Joining Hands to Advance Modernization and Build a High-Level China-Africa Community with a Shared Future."  This theme underscores the commitment to enhancing cooperation and solidarity between China and Africa, focusing on mutual development and progress. However, it also raises important questions about the nature of this engagement and its implications for African nations and their citizens. One of the primary criticisms of inviting leaders from across Africa to such a summit in China is rooted in the perception of power dynamics and respect. For many Africans, attending a summit hosted by a foreign power—especially one as influential and economically powerful as China—can feel like an affront. It underscores the i
