Find out why the Dart mission will deflect an asteroid in Sky & Space 585

For the first time, a kamikaze probe will try to influence the trajectory of an asteroid. This life-size test is the first stone in a strategy to protect humanity. It should be discovered in the file of the new Sky & Space, on newsstands on September 16.

James Webb Telescope : the decryption of the first images

The long-awaited successor to Hubble lives up to its promises. He sees big and in high resolution. As proof: his first images of the distant universe. Breathtaking!

Case : Deflect an asteroid

For the first time, a kamikaze probe will try to influence the trajectory of an asteroid. This life-size test is the first stone in a strategy to protect humanity. A new step after the counting of celestial bodies that are potentially dangerous for the Earth.

Testing: A motorized 305mm Dobsonian for under €2,300

Access to a large diameter telescope is the dream of many amateurs, but many solutions are expensive. As such, Sky-Watcher’s Skyliner series stands out with a 305mm motorized aperture Dobsonian in particular.

Observation: On October 25, partial solar eclipse in France

Even partial solar eclipses are rare from France. October 25, 2022 will allow you to see our star darkened by up to 30%, provided you have an appropriate filter.

Selfie with Mercury

Bepi-Colombo, which will orbit Mercury in 2025, has come close to this planet for the second time. This overview allowed him not only to take a picture with her, but above all to exploit its gravity to adjust its orbit around the Sun.

Chinese trash on the moon?

When an object falls on the Moon, its dusty surface records it faithfully. A new pattern on the lunar surface therefore reveals a recent collision. What body is that? Certainly from the thruster of the Chinese Chang’e 5-T1 mission launched in 2014.

The Resurrection of Picsat

Silent since 2018, the French nanosatellite Picsat has returned to life. Having been struck dumb less than two months after its launch, we never thought we’d hear the exoplanet hunter again. Until radio amateurs pick up its signals, four years later.

handsome survivor

The white dwarf, which forms one of the members of the pair within which type Ia supernovae occur, is usually torn apart by the explosion. But not the one that survived supernova 2012Z. Worse: it shines even more! Because the explosion in 2012Z was only partial. Thus, instead of being ejected, radioactive material could fall back onto the star.

JWST opens an eye

Before observing with its scientific instruments (see p. 6), the James Webb Space Telescope observed the sky with its pointing camera. Result: a first image before its time, consisting of 72 photographs that make up a mosaic.

Heat stroke for SpaceX

The base of the Super Heavy launch vehicle, from SpaceX, caught fire on the launch pad. The starship’s thrusters, whose first orbital test is expected in 2022, ignited violently during statistical tests.

Vega C flies away

Successful start for Vega C! The European rocket, powered by powder engines, took off without incident under the skies of Kourou. Its first stage will act as a lateral thruster for Ariane 6, the future European heavy rocket.

Agreement on ISS

The International Space Station seems far from Earth and its conflicts. Witness the American and Russian space agencies: they will continue to send service flights there with mixed crews.

Samantha goes into the room

The epic continues for Italian astronaut Samantha Cristoforetti. Dressed in a Russian spacesuit, she worked outside the International Space Station for more than 7 hours. She thus became the first European to go into space.

And two for the Chinese station!

China’s space station is getting bigger. The Wentian module, launched by a Long March 5B rocket, docked with the Tianhe core module, which had already been in orbit for more than a year. A third module still needs to be added to the whole, so that the station is complete.

Delivery to Mars by drones

Change of plan for NASA. It is no longer the European SFR rover that will bring the samples collected on Mars by Perseverance to the platform from where they will return to Earth. Perseverance itself will take care of this, aided by two helicopters sent to Mars in 2028.

South Korea is aiming for the moon

South Korea’s Korea Pathfinder Lunar Orbiter (KPLO), also called Danuri, was launched from Cape Canaveral. It should reach the Moon in mid-December and orbit it for at least a year. The six experiments carried out by Danuri aim to answer scientific questions, but also to pave the way for future exploration missions.

The hunt for the Martian crater

About 94 million craters cover the Martian surface, but only one of them is the origin of the Black Beauty meteorite, discovered in Morocco in 2011. Thanks to careful investigative work, we now know which one it is. A history to discover on our website.

Ten candles for curiosity

Curiosity has been studying the Red Planet for ten years now. During the 30-kilometer journey so far, the rover has carried out tireless drilling and experiments to study the habitability of Mars in the past. At the same time, we don’t forget to delight ourselves with photographs that look straight out of a work of science fiction.

Ukrainian science resists

Forced into exile for some, condemned to stay for others, Ukrainian scientists have seen their working conditions completely turned upside down since the start of the war. But the resistance is organized.

Hi Thomas, this is ESA

While in orbit, astronauts are in daily communication with agents on Earth. At the European Space Agency, these privileged contacts are called “eurocom”. Alexandre Fréchette is one of them, and he tells us in this interview what his job consists of, which is crucial for the smooth running of a mission on the ISS.

Mars helicopters

It is therefore Perseverance itself that will bring its soil samples from Mars back to the platform, from where they will take off to Earth (see July 27). But if the rover fails within six years, two small helicopters must supplement it. Teddy Tzanetos, who leads their design, describes in an interview the characteristics of these new machines.
