HEFEI, April 24 (Xinhua) — Zhang Rongqiao, chief designer of China’s planetary exploration program and Tianwen-2 (Tianwen-2) mission Monday, said. China plans to launch the Tianwen-2 mission around 2025 to collect samples from near-Earth asteroids and explore comets, Zhang said at a press conference on China Space Day. which corresponds to April 24 that the main goal of the Tianwen-2 mission The mission is to send a probe to a near-Earth asteroid codenamed “2016HO3” (2016HO3) to collect samples from the asteroid. It will be China’s first collection of samples from interstellar space. if successful adding that a spacecraft will be sent to orbit and landing to collect samples on this asteroid. The spacecraft in the mission above are expected to continue exploring comets in the main asteroid belt between Mars and Jupiter. After completing the main mission

Can SpaceX’s Starship rocket be back just two months after the explosion?

« We’ll be ready once more in a month or two “. Of Elon Musk in the text, Saturday April 22, two days following the long-awaited launch of Starship, designed to be the most powerful rocket ever built. It was just a test that ended with an explosion; we build, we try, we fail and we learn and then we start once more, following the philosophy of SpaceX.

However, as the days pass, we realize that the company has really not gone far from disaster. Mainly in question: the launch pad, obviously not designed to withstand the shock of the simultaneous ignition of the 33 engines of the Starship monster. It is in poor condition, its foundations are bare, and it is hard to see how it might be repaired within two months.

Worse still: rubble was ejected hundreds of meters, even kilometers around. And that’s problematic, because SpaceX’s facility in Boca Chica, Texas borders a protected nature preserve. Obviously, she too was affected by this launch.

It remains to be seen what the FAA, the American aviation authority, which grants licenses for these flights, will say. She examines the consequences of this test and wants to make sure that everything is in line with the commitments made by SpaceX to protect the environment near the installations.

a supersonic black hole discovered by NASA thanks to the Hubble telescope

Thanks to the Hubble Space Telescope, NASA has discovered a “supermassive” black hole leaving behind a trail of stars. Never observed so far, this kind of black hole might not be alone in the universe.

A “supermassive” black hole is tearing through space at full speed and leaving behind a trail of stars 200,000 light-years long, according to an unprecedented discovery announced Thursday, April 6 by NASA.

This enormous monster, whose mass is equivalent to 20 million times that of our sun, is unleashed in the interstellar vacuum and strikes the clouds of gas that are in its path.

Given the outsized forces at play, this gas then turns into a trail of stars, which were spotted by NASA’s Hubble Space Telescope.

“We think we see a wake behind the black hole where the gas cools and can form stars,” Yale University scientist Pieter van Dokkum said in a statement. “What we see are the followingmath. Like the wake of a ship, we see the wake of the black hole.”

Interstellar threesome?

The researchers believe the gas is likely warmed by the collision with the black hole, then cools following it passes, giving rise to the stars seen in its path.

“The gas in front of it is hit by the supersonic impact, at very high speed, of the black hole”, according to Pieter van Dokkum.

Scientists believe that the celestial beast came from a colossal interstellar threesome. According to their theory, two galaxies probably merged around 50 million years ago, causing two supermassive black holes to orbit each other.

But a third galaxy, with its own black hole, would then have collided with this set. What create an unstable and chaotic trio, which ended up ejecting one of the black holes at a phenomenal speed. The monster spotted by Hubble might cover the distance between Earth and the Moon in just 14 minutes.

For us, poor humans, there is no risk of being swallowed by this huge celestial object, according to the researchers responsible for this discovery. All of this happened way out in space and a long time ago, when the universe was half its current age.

We see this phenomenon today because the light took such a long time to reach us.

Discovered by accident

This discovery was made by accident, according to Pieter van Dokkum. Using the Hubble telescope, the scientist “noted (…) a small trail” of stars, “quite amazing, very, very bright and very unusual”. “It was unlike anything we had seen before.”

Never observed before, this kind of black hole might not be alone in the universe, according to NASA.

The new Nancy Grace Roman telescope, due to launch this decade, should allow space to be observed much more widely. He might spot other star trails signaling the presence of one of these colossi.
