How SpaceX lowered costs and reduced barriers to space

How SpaceX lowered costs and reduced barriers to space

On March 2, SpaceX plans to launch its first test of an unmanned Dragon vehicle which is designed to carry humans into low Earth orbit and to the International Space Station. If the test is successful, later this year, SpaceX plans to launch American astronauts from United States soil for the first time since 2011.

Russian Cosmonaut says that the Hole in the ISS was Drilled From the Inside

Russian Cosmonaut says that the Hole in the ISS was Drilled From the Inside

Back in August, the crew of the International Space Station (ISS) was surprised to learn that a leak was responsible for a slight loss in air pressure aboard the station. After investigating, they learned that the cause was a small hole in the Russian Soyuz spacecraft that had docked with the ISS. While the hole was promptly sealed, the cause of it has remained a mystery ever since.

To Avoid Vision Problems in Space, Astronauts Will Need Some Kind of Artificial Gravity

To Avoid Vision Problems in Space, Astronauts Will Need Some Kind of Artificial Gravity

Ever since astronauts began going to space for extended periods of time, it has been known that long-term exposure to zero-gravity or microgravity comes with its share of health effects. These include muscle atrophy and loss of bone density, but also extend to other areas of the body leading to diminished organ function, circulation, and even genetic changes.

Space Station Experiment Reaches Ultracold Milestone

Space Station Experiment Reaches Ultracold Milestone

The International Space Station is officially home to the coolest experiment in space.

NASA's Cold Atom Laboratory (CAL) was installed in the station's U.S. science lab in late May and is now producing clouds of ultracold atoms known as Bose-Einstein condensates. These "BECs" reach temperatures just above absolute zero, the point at which atoms should theoretically stop moving entirely. This is the first time BECs have ever been produced in orbit.

NASA sent a twin to space to study nature versus nurture – and we’re starting to get results

NASA sent a twin to space to study nature versus nurture – and we’re starting to get results

NASA astronaut Scott Kelly recently spent one year in space, while his identical twin brother Mark (a former NASA astronaut himself) stayed on Earth. The mission was part of an important health experiment, looking at how being in space affects our bodies. While the data are still being studied carefully, NASA recently released some intriguing preliminary findings.

So you want to build a Death Star? Here’s how to get started

So you want to build a Death Star? Here’s how to get started

I’m very excited about seeing Rogue One: A Star Wars Story, which tells the tale summarised in the original Star Wars’ opening crawl. This is the story of how the rebels stole the plans to the original “Death Star” – a space station the size of a small moon with a weapon powerful enough to destroy a planet.

Stunning Fiery South Atlantic Sunset As Seen From The International Space Station

Stunning Fiery South Atlantic Sunset As Seen From The International Space Station

An astronaut aboard the International Space Station photographed a sunset that looks like a vast sheet of flame. With Earth’s surface already in darkness, the setting sun, the cloud masses, and the sideways viewing angle make a powerful image of the kind that astronauts use to commemorate their flights.

Factories in space: how extra-terrestrial industry could keep humans alive

Factories in space: how extra-terrestrial industry could keep humans alive

Science fiction truly turned into reality in October 1957 when Sputnik was launched – humankind’s first step beyond the Earth. Since then, progress has been rapid. A significant number of men and women have now travelled to space to explore it and do research.

Astronaut’s First Steps into BEAM Will Expand the Frontiers of Habitats for Space

Astronaut’s First Steps into BEAM Will Expand the Frontiers of Habitats for Space

On Monday, June 6, astronaut Jeff Williams will enter the first human-rated expandable module deployed in space, a technology demonstration to investigate the potential challenges and benefits of expandable habitats for deep space exploration and commercial low-Earth orbit applications.

NASA to Attach, Test First Expandable Habitat on International Space Station

NASA to Attach, Test First Expandable Habitat on International Space Station

The first human-rated expandable structure that may help inform the design of deep space habitats is set to be installed to the International Space Station Saturday, April 16. NASA Television coverage of the installation will begin at 5:30 a.m. EDT.

Astronaut’s return to Earth will prepare us for mission to Mars – here’s why

Astronaut’s return to Earth will prepare us for mission to Mars – here’s why

Would you like to spend a year gazing down from the International Space Station? Before you pack your bag, you should think about what actually might happen to you in microgravity, away from the protection of the atmosphere and magnetosphere. Thanks to two astronauts who’ve recently landed back on Earth, we’ll now be able to find out.

Five key findings from 15 years of the International Space Station

Five key findings from 15 years of the International Space Station

The International Space Station is the longest-running continuously inhabited human outpost in space – this year it celebrated its 15th anniversary. As the ISS orbits the Earth it is essentially in a state of free fall, counteracting the Earth’s gravity and providing an ideal platform for science in space.

Getting Into the Flow on the International Space Station

Getting Into the Flow on the International Space Station

Think about underground water and gas as they filter through porous materials like soil and rock beds. On Earth, gravity forces water and gas to separate as they flow through the ground, cleaning the water and storing it in underground pools. Gravity's role is significant in the process, both in nature with ground water and in chemical processes such as water reclamation reactors.
