NASA and ESA finalize agreement to build Gateway deep space outpost


Scheduled to begin construction in cislunar orbit in 2024, the Gateway outpost is intended to act as a staging point for missions to the lunar surface, and deep space, and, ultimately, for the first crewed missions to Mars. One-sixth the size of the International Space Station (ISS), the Gateway will be assembled as modules launched into a Near Rectilinear Halo Orbit, where it will not revolve around the Earth or the Moon, but one of the Lagrange points where the gravitational fields of the Earth and Moon balance out.

NASA's Perseverance Rover Is Midway to Mars


NASA's Mars 2020 Perseverance rover mission has logged a lot of flight miles since being lofted skyward on July 30 – 146.3 million miles (235.4 million kilometers) to be exact. Turns out that is exactly the same distance it has to go before the spacecraft hits the Red Planet's atmosphere like a 11,900 mph (19,000 kph) freight train on Feb. 18, 2021.

NASA’s OSIRIS-REx Successfully Stows Sample of Asteroid Bennu


NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission has successfully stowed the spacecraft’s Sample Return Capsule (SRC) and its abundant sample of asteroid Bennu. On Wednesday, Oct. 28, the mission team sent commands to the spacecraft, instructing it to close the capsule – marking the end of one of the most challenging phases of the mission.

Chinese spacecraft set for Mars landing in May: state media


BEIJING (Reuters) - A Chinese spacecraft is expected to land on Mars in May, state-run media reported on Thursday, citing a space agency official.

The spacecraft, which left Earth in July, is set to land in Utopia Planitia, a plain in the northern hemisphere of Mars, the China News Service reported, citing Liu Tongjie, spokesman for the Mars mission.

Separate spacecraft launched by the United States and the United Arab Emirates this year are also en route to Mars, though only the U.S. one will attempt a landing.

Unusual molecule found in atmosphere on Saturn's moon Titan


Saturn's largest moon, Titan, is the only moon in our solar system that has a thick atmosphere. It's four times denser than Earth's. And now, scientists have discovered a molecule in it that has never been found in any other atmosphere

The particle is called cyclopropenylidene, or C3H2, and it's made of carbon and hydrogen. This simple carbon-based molecule could be a precursor that contributes to chemical reactions that may create complex compounds. And those compounds could be the basis for potential life on Titan.

We finally know what has been making fast radio bursts


Today, researchers are announcing they've solved one of the questions that has been nagging them over the past decade: what exactly produces the weird phenomena known as fast radio bursts (FRBs)? As their name implies, FRBs involve a sudden blast of radio-frequency radiation that lasts just a few microseconds. We didn't even know that FRBs existed until 2007 but have since cataloged hundreds of them; some come from sources that repeatedly emit them, while others seem to burst once and go silent.

CERN scientists design trap to transport antimatter between facilities


The BASE collaboration has now designed a new device, called BASE-STEP, that could help scientists move antimatter around to other facilities. The key to the system is what’s known as a Penning trap, which uses electric and magnetic fields to suspend antiprotons (the antimatter version of protons) away from the walls of the container. But there are atoms in air too of course, so the trap also stores them in a vacuum. BASE-STEP would be made with two Penning traps – one to receive and release antiprotons and a second one that acts as a storage reservoir.

Penning traps are already in use in antimatter facilities, with CERN previously showing they can store antiprotons for over 400 days – a huge improvement over the record of 16 minutes, set in 2011. But the real challenge for the team was to then make these devices portable.
