Ellen Stofan, Former NASA Chief Scientist, on why space exploration is vital to humanity. Humans are about to return to the Moon, and are working on a mission to Mars. Former NASA chief scientist Ellen Stofan and current undersecretary for science and research at the Smithsonian explains why space exploration is so important for humanity.
Space is getting more crowded and more commercialized. This is leading to a growing risk of collisions between satellites and space junk, and means that new regulations on the use of space are urgently needed. Those are some of the conclusions of the World Economic Forum’s Global Risks Report 2022, which warns that if satellites fail, whether ...
1. Space will be a larger part of the global economy. By 2035, the space economy is set to reach $1.8 trillion, up from $630 billion in 2023 and averaging a growth rate of 9% per annum – a figure significantly above the growth rate of global GDP. Space-based and/or enabled technologies such communications; positioning, navigation and timing ...
The space sector is evolving rapidly, with new public- and private-sector actors propelling it towards commercial launch and space tourism, ever-larger constellations that provide connectivity and ever-more precise Earth observation, as well as partnerships for lunar exploration and beyond. As the domain undergoes this important transformation, the Global Future Council on Space will explore ...
“We travel together, passengers on a little space ship, dependent on its vulnerable reserve of air and soil; all committed for our safety to its security and peace; preserved from annihilation only by the care, the work, and I will say, the love we give our fragile craft.”
The space economy is booming. The term “space economy” covers the “goods and services produced in space for use in space, such as mining the moon or asteroids for material”, according to the Harvard Business Review. The OECD defines it as any activity that involves “exploring, researching, understanding, managing, and utilizing space”.
One study estimated that 1,000 space launches per year could create a layer of black carbon particles capable of causing the loss of 5% or more of Antarctic sea ice. As private commercial interest in space increases, a wider variety of governments are also likely to initiate launches. More than a dozen countries now have the ability to send ...
Mega-constellations in space pose a threat to climate. The present pace of growth is unsustainable. Over the past six decades, about 11,000 satellites have been launched, of which 7,000 remain in space. But that number could swell to the hundreds of thousands by the end of this decade as private companies like Elon Musk’s Starlink and Amazon ...
Human presence also creates orbital flotsam – such as cameras, pliers, an astronaut’s glove, a wrench, a spatula, even a tool bag lost during space walks. Some debris is created naturally from the impacts of micrometeoroids – dust-sized fragments of asteroids and comets. With limited lifetimes, operational satellites can become space debris.
Here are five ways space tech can help improve life on Earth. Benefits of space technologies for the SDGs. Image: UN. 1. Frontier technologies to tackle climate change. The arrival of frontier technologies such as Space 2.0 systems – along with other innovations including artificial intelligence (AI), 5G, the Internet of Things (IoT) and ...
