Watch as NASA celebrates 20 years of humans living on the International Space Station

Today marks the 20th anniversary of the first long-term mission to the International Space Station, known as Expedition 1. Ever since then, there have always been a handful of humans living and working in orbit on the ISS — a continuous presence of people in space.

Prior to that mission, most of NASA’s human spaceflight program revolved around launching relatively quick, weeks-long trips to orbit on the agency’s Space Shuttle. But in the mid-1990s, NASA began sending its astronauts to space for much longer trips to live on Russia’s old Mir space station. Once the US, Russia, and their international partners started piecing together the International Space Station, NASA started sending some of its astronauts to stay for months at a time beginning in 2000 — and there have been people on board ever since.

As part of Expedition 1, a crew of

Space station marking 20 years of people living in orbit

CAPE CANAVERAL, Fla. (AP) — The International Space Station was a cramped, humid, puny three rooms when the first crew moved in. Twenty years and 241 visitors later, the complex has a lookout tower, three toilets, six sleeping compartments and 12 rooms, depending on how you count.

Monday marks two decades of a steady stream of people living there.

Astronauts from 19 countries have floated through the space station hatches, including many repeat visitors who arrived on shuttles for short-term construction work, and several tourists who paid their own way.

The first crew — American Bill Shepherd and Russians Sergei Krikalev and Yuri Gidzenko — blasted off from Kazakhstan on Oct. 31, 2000. Two days later, they swung open the space station doors, clasping their hands in unity.

Shepherd, a former Navy SEAL who served as the station commander, likened it to living on a ship at sea. The three

Living near a White Dwarf

Recently, the first planet to orbit a white dwarf—the latter named WD 1856+534—was discovered through its transit in front of the tiny star once every 1.4 days. Remarkably, this giant planet, WD 1856b, is seven times bigger than the stellar remnant it transits. Most likely, there are rocky, Earth-size planets at similar distances from other white dwarfs—in which case they would possess a surface temperature similar to that of Earth. This hits us close to home.

In about a billion years, the sun will brighten up enough to boil away the oceans on Earth through a runaway greenhouse effect. In order to survive, our civilization will have to migrate outwards in the solar system. Seven billion years later, the core of the sun will shrink to its remnant, a white dwarf, carrying about half of the solar mass with the rest lost.

A white dwarf is a hot, dense, metallic

Isolating in dorm rooms, no socializing, and online classes. The British university students living through the pandemic

By now, British students should have been enjoying their first weeks of university and all the freedom and chaos the experience typically brings. Instead, they have been battling a far different reality.

Tara Kelly, 20, is in her final year at the University of Oxford, but says the city is far different from the Oxford she left last year.

With coronavirus cases rising, particularly in northern parts of England, many have been forced to self-isolate in student halls, unable to leave even to go food shopping. Under government guidance, updated at the end of last month, students in areas with additional restrictions aren’t even allowed to return to their family homes, in case that increases the risk of the COVID-19 infection spreading.

Why Global Citizens Should Care

Education is a basic human right. But many children still do not have the opportunity to learn, especially if they live in poverty or are girls. You can join us in taking action on this issue here

Children living in poverty face many barriers to accessing an education. Some are obvious — like not having a school to go to — while others are more subtle, like the teacher at the school not having had the training needed to help children learn effectively.

Increasing access to education can improve the overall health and longevity of a society, grow economies, and even combat climate change. Yet in many developing
