A recent NASA mission successfully demonstrated the performance of a non-toxic “green” propellant, creating opportunities for its use in a wide range of future spacecraft. NASA flew the Green Propellant Infusion Mission (GPIM) spacecraft as one of the payloads on the Space Test Program 2 mission that launched on a SpaceX Falcon Heavy in June 2019. The spacecraft’s mission ended when it reentered in October 2020 after a series of deorbiting maneuvers.

NASA engineers are planning a robotically constructed kilometre diameter radio telescope that will fit in a giant crater and study radio waves from the big bang.

"It's not everything we hoped it would be."

NASA declared the Mars digger dead Thursday after failing to burrow deep into the red planet to take its temperature.

This liquid fuel engine is a beast.

The US space agency (Nasa) is about to put its latest rover, Perseverance, on Mars. But we shouldn't forget that the existing robot, Curiosity, is still there and working well following its landing in equatorial Gale Crater back in 2012. Curiosity celebrates 3,000 Martian days, or Sols, on the surface of the Red Planet on Tuesday. The Mission Science Team has collected together a series of pictures that record some of the rover's major achievements.

The Big Bang theory is a cosmological model describing how our current, observable universe came to be. But there is still much to learn about the concept, particularly when it comes to what occurred in those early microseconds after the big bang itself. What happened in that split second when our universe appeared? NASA wants to find out. To do so, the space agency has designed a space telescope that will be able to probe the universe for evidence of those earliest moments.

When the 60-year-old Arecibo Observatory collapsed in 2020, the crash didn’t just take down one of the world's preeminent radio telescopes, it also dealt a massive blow to the future of radio astronomy. Arecibo may have been old, but it also had unique capabilities that made it ideal for studying things like gravitational waves, as well as mapping the surfaces of asteroids as they slip by Earth.

The National Aeronautics and Space Administration (NASA) says it has successfully grown its very own batch of radishes on the International Space Station (ISS). The successful project took place last month when researchers were able to grow six packs of radishes in space. This is great news for scientists attempting to produce vegetables and fruits in environments with low levels of gravity.

In 2017, NASA space probes detected a massive, human-made 'barrier' surrounding Earth.

After decades of nostalgia for the Apollo program, it’s time for NASA to send astronauts on a radical new adventure, worthy of America’s pioneering spirit

50 years after the first spacecraft touched down on our super hot neighbor (and promptly died), NASA has a plan for a tougher mechanical lander.

There was no clearer set of contrasts between how SpaceX and NASA approach launch vehicle development than the dueling tests the two performed in early December of Starship and Space Launch System, respectively. It was hard to miss the Dec. 9 test flight of SpaceX’s Starship SN8 prototype, the first time the vehicle flew more than a couple hundred meters off the pad. It soared into the Texas sky propelled by its three Raptor engines...

The US space agency (Nasa) has released an animation showing how its one-tonne Perseverance rover will land on Mars on 18 February. The robot is being sent to a crater called Jezero where it will search for evidence of past life. But to undertake this science, it must first touch down softly. The sequence of manoeuvres needed to land on Mars is often referred to as the "seven minutes of terror" - and with good reason.

Every monkey held by Nasa was put to death on a single day last year, documents obtained by the Guardian show, in a move that has enraged animal welfare campaigners. A total of 27 primates were euthanized by administrated drugs on 2 February last year at Nasa’s Ames research center in California’s Silicon Valley, it has emerged.

SpaceX Boca Chica is now transitioning towards the next launch campaign, with Starship SN9 expected to roll to the launch pad this week. There remains a slim chance SN9 will be ready to launch before the end of the year, repeating the flight profile that almost saw SN8 return in one piece.

A Texas-based company, ICON, wants to help NASA return to the Moon in 2024 by 3D printing a lunar base from moon dust.

NASA has selected three astronauts for a future SpaceX commercial crew mission to the International Space Station as it leaves open the possibility of exchanging seats with Russia. NASA and the European Space Agency jointly announced Dec. 14 they had assigned NASA astronauts Raja Chari and Tom Marshburn and ESA astronaut Matthias Maurer to the SpaceX Crew-3 mission. That commercial crew mission is scheduled for launch in the fall of 2021.

The US space agency NASA published a voluminous report on Monday outlining the scientific priorities for the Artemis III astronauts it intends to send to the Moon in 2024. One of the goals will be to bring back a total of 85 kilograms (187 pounds) of lunar samples, both from the surface and sub-surface, more than the average 64 kilograms brought back by Apollo mission members between 1969 and 1972.

On November 30, NASA announced the Orion spacecraft — which is expected to play a critical role in returning U.S. astronauts to the Moon for the first time in more than 50 years — may be experiencing a setback. According to a blog post from NASA, when engineers were powering up the spacecraft before pressurizing the crew module, they noticed an issue in the power and data unit.
