Another week passed with quite a bit of news about space exploration and astronomy. If you are not able to keep up with everything, the “summary” has arrived to make your life easier and keep you updated on what’s going on in the world of science. We tracked the successful landing of the Chinese Zhurong rover on Mars and its first photos, saw photos of the solar coronal mass ejection, and more!
Want to stay on top of everything? so let’s go!
The Chinese rover Zhurong has landed on Mars …
The week started with great news: The Chinese Tianwen-1 mission to the Red Planet has gone as planned. The country’s first spacecraft to reach Mars soil landed at a place called Utopia Planetia, the largest collision basin there. It took a few months for the team to decide the site, but in the end good landing conditions prevailed for the pit of selection.
The Zhurong rover will spend the next 90 days exploring the area’s surface to study soil formation, as well as looking for signs of frozen water. Meanwhile, the orbiter will remain in the planet’s orbit, serving as a relay for the probe data to Earth.
… and you’ve already taken your first photos!
While waiting to leave the comfortable protection of the landing module, the probe has already taken its first images on Mars, indicating that the instruments are working well. Photos show Zhurong on the landing gear, as he traveled to the Red Planet. These are the first images of the surface of Mars produced by a mission that has not been carried out by the United States.
The black and white image was captured by the Obstacle Avoidance Camera, which is located at the front of the rover, and shows the ramp in front of the vehicle through a wide-angle lens. The color image was taken by the navigation camera, which shows the solar panels and the vehicle’s antenna already deployed.
Coronal mass ejection from the Sun video
The Solar Orbiter probe was able to capture the first video images showing coronal mass ejection, which is essentially volcanic eruptions of particles from the solar atmosphere exploding and being ejected by the solar system. The pictures were taken while the probe was flying in February of this year.
At the time of taking the picture, the solar probe was “behind” the sun, meaning that the star was between our planet and the probe, when the instruments were connected for testing, because the probe had not yet reached its final destination. This means it was a coincidence that the sun was photographed when the tosses were taking place!
A daytime meteor in the sky of Bahia
On Monday morning, residents of some cities in Bahia were surprised by a luminous object across the sky in broad daylight, followed by a loud noise. It is rare for such an event to be so bright during the day, but even with the daytime sky and partly cloudy, the starting point could be seen.
Although somewhat frightening, the missile posed no threat to the population. Bolides are meteorites that take longer to burn as they enter Earth’s atmosphere, but shortly thereafter they burst and disintegrate.
Delayed launch of the James Webb Telescope again?
The long-awaited (and long-awaited) launch of the James Webb Space Telescope can be delayed again. The current date is still set as October 31, except that a report released by the Government Accountability Office (GAO) reveals the chance that the missile responsible for the launch will pose some problems in history.
In fact, there are already some anomalies in the Ariane 5 missile, and the launch missions it was due to have been “somewhat” postponed. Ago NASA James Webb’s launch date hasn’t changed yet, as there is still a chance to fix problems with the missile before October 31.
Neutron stars may be larger than previously thought
Neutron stars, the most dense visible objects in the universe, are often described as a sphere with a radius of only 10 kilometers, but new research indicates that they are slightly larger than that. The article is based on another study conducted over the past decade, measuring the neutron “skin” around the lead nucleus.
The researchers achieved the breakthrough by showing that the new measurement of the lead atom indicates that the neutron star has an average radius between 13.25 and 14.25 km. This does not change the fact that these little girls are super thick!
What is the best radio telescope for the far side of the moon?
NASA is choosing radio telescope designs designed to build on the far side of the moon that will become real. One such project is the Lunar Crater Radio Telescope (LCRT), which aims to convert a crater about 0.8 km in diameter into a large radio telescope, making use of the equivalent shape of a geological accident. The other is FARSIDE, which has a diameter of over 9 kilometers.
The idea of building a radio telescope on the far side of the moon has been around since the 1960s, but only now can robotic technology make this concept viable. The idea is that in this region of the Moon, the instrument would be so isolated from Earth’s light and radiation that it would be able to pick up the low-frequency radio waves remaining from the beginning of the universe. In other words: he will be able to uncover more mysteries about the events immediately after the Big Bang!
The former lieutenant says he has seen UFOs daily for nearly two years
Former Navy pilot Lieutenant Ryan Graves says that in 2014, the crew of his F / A-18F squadron began detecting unidentified atmospheric phenomena – also known as UFOs – hovering over restricted airspace near Virginia Beach. https://t.co/ExjTiMzkRM pic.twitter.com/ny6pG6ZvKB

That was something to talk about! Former US Navy Lieutenant Ryan Graves said he saw unidentified flying objects performing strange maneuvers every day for about two years. The maneuvers were alleged to have taken place in restricted airspace near Virginia Beach. Of course, UFOs are, as the acronym says, UFOs that are unrecognizable, not necessarily alien ships – and Graves knows that. He even commented that these things could pose a real threat if planes are from other countries.
There was still room for speculation of all kinds, as Graves was unable to define the beings’ technique. It is believed that it may be a surveillance program from a country like China or Russia. Luis Elizondo, another interviewee, says he has seen objects that appear to have very advanced technologies, capable of flying at 20,000 km / h and evading radars.
