Russia wants to send cosmonauts to China space station

The mission would be complicated.
Russia is evaluating options that would allow its cosmonauts to visit China’s new space station.

Astronomers Pedro Bernardinelli and Gary Bernstein discovered a space object recently that has an orbit around the sun and also stretches into the Oort cloud—they have named it 2014 UN271. The researchers made the discovery while studying archival images collected for the Dark Energy Survey over the years 2014 to 2018. Since its discovery, entities such as the MMPL forum, the Minor Planet Center and JPL Solar System Dynamics have been tracking the object and have found that it will make its closest approach to Earth in 2031.
Measurements of the object put it between the size of a very small planet and a comet—it is believed to have a diameter of 100 to 370 km. If it turns out to be on the larger end of that spectrum, it would mark the largest Oort cloud object discovered to date. But it is the path of the object that has drawn the attention of astronomers—its orbit is nearly perpendicular to the plane created by the nine inner planets and takes it deep into the solar system and into the Oort cloud. One trip around the sun has been calculated to take 612190 years. It is currently moving deeper into the solar system, which means astronomers will have an opportunity to observe it 10 years from now.
Sam Deen, an amateur astronomer posting on the MMPL forum described the find as “radically exceptional.” Study of 2014 UN271 as it draws closer will allow researchers to analyze an object that sometimes passes through the Oort cloud at distances as close as 10.9 AU from the sun—near the orbit of Saturn. As it draws nearer to the sun, it is likely to develop a comet-like tail as frozen material on its surface is vaporized. It is not clear just yet, however, how bright 2014 UN271 will appear in the night sky here on Earth—but it is likely that its brightness will fall somewhere between that of Pluto or its moon Charon; enough for amateurs and professionals alike to get a good view of it using strong telescopes.
The celestial body could come close enough to the Sun for us to launch a mission.
Astronomers discovered a new object in an eccentric orbit around the Sun, which could come as close as 11 AU to our star.
The luxury six-hour roundtrip flight will include plush reclining seats, anti-glare windows for photography, and livestream-capable WiFi.
O„ o!!!
Estimated to be between 100 to 370 kilometres in width, the object is bigger than the normal specification of a comet and is likely to be a dwarf planet.

Boeing finished loading hydrazine and nitrogen tetroxide maneuvering propellants over the weekend into the company’s second space-rated Starliner capsule at the Kennedy Space Center, days after stacking of its Atlas 5 launcher began a few miles away at Cape Canaveral Space Force Station.
The capsule is scheduled to launch July 30 at 2:53 p.m. EDT (1853 GMT) on a test flight to the space station. If all goes according to plan, it will clear the way for Boeing to carry astronauts to the station, possibly before the end of this year.
That will be welcome news to NASA, which has funded the Starliner spacecraft’s development through its a commercial crew program in a cost-sharing arrangement with Boeing. NASA’s commercial crew contracts with Boeing since 2010 are valued at more than $5 billion.
NASA and the European Space Agency recently announced the approval of three new missions to explore Venus.
How did this scorching planet evolve to be so different than its sister, Earth? 3 NASA and ESA missions are beginning the search for answers.
More than 90 years ago, astronomer Edwin Hubble observed the first hint of the rate at which the universe expands, called the Hubble constant.
Almost immediately, astronomers began arguing about the actual value of this constant, and over time, realized that there was a discrepancy in this number between early universe observations and late universe observations.
Early in the universe’s existence, light moved through plasma — there were no stars yet — and from oscillations similar to sound waves created by this, scientists deduced that the Hubble constant was about 67. This means the universe expands about 67 kilometers per second faster every 3.26 million light-years.
NASA successfully detects an earthquake aftershock using balloon-borne seismometers. This new balloon technology may be used to explore Venus’ deep interior from high in its atmosphere.
This guy is selling land on the Moon.
I didn’t know if it was a gimmick, a scam, or a real thing…so we had to track him down and tell you his story from the beginning!
