A mission for five years, ESAs ExoMars Trace Gas Orbiter recently captured a snapshot that is as interesting as it is intriguing. The image indeed displays three craters aligned from the smallest to the largest. A disturbing snapshot taken by the ExoMars Trace Gas Orbiter Developed by the European

Titan is one of the most intriguing places in the Solar System. NASA plans to send a mission there dubbed Dragonfly in the 2030s. It will be the first mission to explore the surface of this moon. The main objectives of this unique project were shared a few days ago. Our planet aside, Titan, Saturns

Based on data from the Osiris-Rex probe, NASA recently assessed the likelihood that the asteroid Bennu, which is on the podium of the US agencys Sentry risk table, may one day strike Earth. Seven months after landing on the asteroid Bennu to collect samples, the OSIRIS-REx probe began its return jo

Flying astronauts to the Moon requires a lot of fuel. To get there, SpaceXs Starship will need to be refueled in Earth orbit, before it can target our satellite. But how many tankers will be needed exactly? To send humans to the Moon, SpaceXs Starship will need to be refueled in space. Concretely,

Since 2012, the Curiosity rover has been surveying Gale Crater, which may have housed a large lake several billion years ago. In this formerly aqueous environment, the main objective of its mission was to probe the potential for habitability of the planet Mars. However, we could have been wrong. 9

Experiencing an emotional breakdown while aboard the ISS in 2018, American astronaut Serena Auñón-Chancellor allegedly drilled a hole in one of the modules Russians in order to return to Earth sooner, according to the public news service TASS. NASA denies these defamatory accusations. Throwback to

Jeff Bezos company Blue Origin has just taken its fight against NASAs manned lunar landing program to federal court. The complaint is part of a months-long crusade by the company to win some of the funds offered by the US agency. This new twist may, once again, delay the development of the Artemis p

According to a NASA-led team, Mars may harbor an underground microbial ecosystem capable of surviving on chemical activity fueled by radioactivity. The only condition would be that the water is present, which has not yet been proven. To find traces of past life on Mars, researchers have long looked

Based on data from the Cassini spacecraft, astrophysicists recently pinpointed the size of Saturns core by examining its influence on the large C ring of the planet. planet. The team determined that this core made up of a combination of ice, rock, hydrogen and helium was about fifty times more massi

Astronomers announce that they have identified a contingent of young stars accompanied by clouds of gas protruding from one of the spiral arms of the Milky Way. Spanning some 3,000 light-years, this is the first time such a structure has been identified in the Galaxy. Astronomers have a fairly roug

A Chinese team recently identified a location on the Tibetan Plateau capable of hosting one of the most powerful telescopes in the world. According to the authors of the study in question, the site meets all the key parameters of a world-class observatory. These days, the leading observatories are

A few months ago, a Chinese satellite broke into several pieces. In reality, according to an astrophysicist specializing in satellites, he encountered space debris. The expert thinks that the frequency of this type of incident will increase in the future, proportionally to the increase in the quanti

SpaceX is offering to use its Starship spacecraft to rapidly deploy its second-generation Starlink constellation. This approach could provide denser rural coverage while limiting the number of satellites in orbit. SpaceX officially plans to launch 12,000 Starlink satellites into low orbit (LEO). Ho

Landed on Mars in mid-May, the Zhurong rover has just completed its main mission of 90 sols. Still in very good condition, the vehicle will continue to explore its environment in order to learn more about the red planet. On May 15, around 4 a.m. (Beijing time), the Chinese Tianwen-1 probe dropped i

A team of astronomers announces that they have identified an asteroid orbiting the sun faster than any of its known relatives. Measuring only one kilometer in diameter, it was spotted from Chile about ten days ago. The fastest orbiting asteroid The rock, known as 2021 PH27, orbits our star every 11

The Japanese space agency (JAXA) is preparing for a major mission to bring back samples from the moon Phobos by 2029. In doing so, the scientists hope to find clues to the origins of the two Martian moons and Mars itself, and possibly even traces of past life. Japan targets Phobos JAXA recently con

Recent hacked emails testify to intensive lobbying by United Launch Alliance leaders to discredit SpaceX. These exchanges are essentially about so-called privileged relations between NASA, the Trump administration, Elon Musk and China. A few days ago, Jeff Bezos company Blue Origin took its fight a

Thanks to the InSight mission, NASA was able to determine the internal structure of Mars down to its core, highlighting several differences with our planet. This scientific breakthrough is reported in a trio of articles published in the journal Science . A first inner map The Earths mantle was firs

Are there extraterrestrial civilizations able to think and build technologies allowing interstellar travel? An international research project called Galileo, led by Professor Avi Loeb, intends to know. Led by a multi-institutional team of scientists and piloted by Harvard University, the Galileo pr

The Europa Clipper mission, which targets the Jovian system, was originally scheduled to launch aboard NASAs powerful SLS rocket in 2024. Agency officials finally opted for a commercial solution, as the SLS was no longer available for this type of mission. And it was (again) SpaceX that was chosen.
