In a letter to current NASA administrator Bill Nelson, Blue Origin founder Jeff Bezos said his company could give up more than two billion dollars in funding if NASA awarded it a manned lunar landing system contract. First, a little reminder of the situation The United States wants to establish a l

Based on data from the Hubble telescope, astronomers have discovered the first evidence of water vapor in the atmosphere of Ganymede, the largest moon of Jupiter. This water vapor forms when the ice on the moons surface changes from a solid solid state to a gas state. Ganymede, the largest moon of

NASA and its prime contractor Lockheed Martin are one step closer to launching their Lucy mission. The vessel has just completed the preliminary examination authorizing its expedition to the launch site, at Cape Canaveral (Florida). The objective of this mission will be to study several Trojan aster

The company Blue Origin, founded by Jeff Bezos, is currently looking into the development of a reusable, stainless steel New Glenn rocket second stage, an approach adopted by SpaceX for several years. The goal:to reduce the cost of access to space. Blue Origin recently distinguished itself with the

Astronomers are proposing a new tool dubbed SatHub to deal with the growing threat of mega-satellite constellations that could interfere with astronomical observations. Constellations of satellites are not new, but they have proliferated in recent years thanks to increasingly easy access to space.

Astronomers have discovered thousands of exoplanets, but few have been directly imaged as most end up drowning in the brightness of their planets. star. A University of Hawaii student recently isolated a planet far enough from its host to be seen directly. You will find it only 35 light years from E

Researchers suggest that the possible bodies of liquid water isolated under the surface of Mars a few months ago are actually layers of clay. Divided into several studies, this work has been published in the Geophysical Research Letters. Liquid water on Mars? Three years ago a team of researchers s

The United States Government Accountability Office (GAO) has just rejected Blue Origin and Dynetics protests filed over NASAs award of a single contract from lunar lander to SpaceX. A decision that Jeff Bezos, boss of Blue Origin, has a hard time digesting. The GAO supports SpaceX A few months ago,

Recently in the United States, a rapper publicly stated that he intended to buy a planet. Is it really possible? What the law says ? Is this just a publicity stunt? Complicated from a legal point of view With the many discoveries of exoplanets, the hope of finding life outside the Earth has never b

NASA and Boeing are preparing for the second test flight of the Starliner capsule which was unable to reach the ISS during its first test. If all goes as planned, a first manned mission could then be scheduled by the end of the year. Seven years ago, NASA contracted with SpaceX and Boeing to operat

Researchers recently shed light on a strange star moving at over 3 million km/h on a path leading it out of our Galaxy. How can such behavior be explained? A star that flies at full speed! About 2,000 light-years from Earth evolves a particular star. LP 40−365, its name, is one of a unique breed of

The Solar Orbiter and BepiColombo probes will perform flybys of Venus in a few days less than thirty hours apart in order to take advantage of a gravitational braking system . Travel in the Solar System is not in a straight line and is very energy intensive. To reach a planet, moon or asteroid whil

Next month, SpaceXs Inspiration4 mission will carry four passengers including its commander, American businessman Jared Isaacman. Recently, Elon Musk and Netflix announced an unprecedented partnership. The streaming platform intends to produce a series on the mission. A documentary mini-series A ne

Chinas meteoric rise in space science and exploration, as well as its new partnership with Russia should cause the United States to reconsider the absence of bilateral collaborations. The United States is still the world leader in space exploration, and by far. However, China is methodically advanc

The Russians are preparing to shoot a film on board the ISS and it will be a big first. The first details regarding the story of this film have recently been shared. There will be talk of a rescue operation. The Roscosmos space agency announced the news last May. A film crew will be sent to the Int

NASA and Boeing are working together to attempt a second test flight of the Starliner capsule, which was unable to reach the ISS during its first test. However, the launch window will not be open forever. Boeing has been working since 2014 on the development of its Starliner capsule as part of a co

Jeff Bezos is clearly not ready to let go of NASAs proposed manned lunar landing contract. Blue Origin has just released an infographic highlighting the extreme complexity of a mission involving SpaceXs Starship. A desperate… and hopeless manoeuvre? As you know, NASA has set its sights on SpaceX to

Virgin Galactic, the space tourism company run by Sir Richard Branson, is offering new tickets for sale to fly aboard its USS Unity suborbital plane. The cost of a few minutes of zero gravity for new customers will be much higher than before, and they may have to wait a while before they can enjoy i

When a system hosts one of the smallest rocky planets ever discovered, a planet dominated by oceans, and even the possibility of an Earth-like world evolving the habitable zone of its star, astronomers are taking note. You will find all this beautiful world just 35 light years from Earth. At the he

A few days ago, Virgin Galactic announced that its founder, the British billionaire Sir Richard Branson, would attempt to reach space on July 11 with his crew, i.e. nine days before Jeff Bezos, the founder of the company Blue Origin. But will they actually reach space? Virgin Galactic is set to lau
