"Right now, traditional habitat designs for Mars are like a turtle — carrying our homes with us on our backs — a reliable plan, but with huge energy costs."

After months of anticipation, SpaceX's new crew-worthy spacecraft, Crew Dragon, is finally prepped for its last major test before astronauts can begin using it for rides to the International Space Station. But finding the right weather conditions could be a roadblock this weekend.

NASA researchers are investigating the potential of mycelia — the mass of nutrient-absorbing, widely branching underground threads that make up much of a fungus's bulk — to help construct outposts on the moon and Mars.

The TESS space telescope has found its first Earth-sized planet with conditions that might be right for life orbiting a small star 100 light-years away

Nasa and SpaceX are set to destroy a rocket as part of an emergency test. The procedure, known as an "In-Flight Abort Test", will ensure that a new capsule meant for carrying astronauts would allow them to escape in the case of a disastrous launch. But it will also mean destroying one of SpaceX's Falcon 9 rockets to understand what would happen if one really exploded by accident.

As Buzz Aldrin approaches his 90th birthday, Rod Pyle chats to the Apollo 11 astronaut about his life, legacy, and humanity's future in space.

Both SpaceX and Boeing are part of NASA's Commercial Crew Program, which aims to bring astronaut launches back to US soil for the first time since the end of the space shuttle era in 2011. SpaceX already successfully sent an uncrewed Crew Dragon capsule to the ISS earlier this year. Boeing was hoping to match SpaceX's achievement, but a glitch caused Starliner to use up too much fuel. Instead of meeting up with the ISS, Starliner will attempt to come back to Earth early.

The suits that kept Nasa’s astronauts alive in the cold void of space were sewn, one painstaking stitch at a time, by a talented team of expert seamstresses.

2019 was the shot. 2020 is the chaser.

2019 was the shot. 2020 is the chaser. Four countries are sending robots to Mars, private companies will send humans into orbit, and we’re inching closer to seeing NASA return astronauts to the moon.

NASA is going to be sending something it calls a “robot hotel” to the International Space Station aboard the next commercial resupply mission, which is set to launch aboard a SpaceX Falcon 9 rocket this week. The robot hotel is more formally known as the “Robotic Tool Stowage̶…

"Transparency for the taxpayer."

Luckily, Voyager 2's instruments are in somewhat better shape than Voyager 1's, so scientists were able to observe the transition from the heliosphere, which is dominated by the sun, to the interstellar medium (ISM). 

They don't know why levels are spiking and dropping.

Government oversight officials issued a scathing report about delays in NASA's commercial crew program, warning that Boeing and SpaceX are facing "significant safety and technical challenges" with their spacecraft — which could leave NASA astronauts stranded on the ground next year.

NASA's Inspector General (IG) predicts that the US will have to spend $90 million per seat for flights on the CST-100 Starliner, a spacecraft currently being constructed by Boeing

Engineers plan to collect rocks on Mars and bring samples to Earth, in one of the most complex robot space projects envisaged. The scheme, being developed by Nasa and the European Space Agency (Esa), will involve robot rovers finding rocks that might contain evidence of past life.

Astronomers have spotted a huge stellar black hole in our galaxy, many times bigger than ever thought possible. Scientists thought that such black holes could only reach about 20 times the mass of the Sun. But the newly discovered object is 70 times great, astronomers from the Chinese Academy of Sciences say.

ASA recruits a diverse array of scientists to study our planet and our universe. But one female research assistant, based in Pasadena, California, has a rather unusual resume and bio.

Future Mars astronauts won't have to carry all their water from Earth.
