NASA's asteroid sampling mission Osiris-Rex arrives at the destination Benennu

The asteroid sampling mission launched in September 2016 after two years of sailing, Osiris-Rex finally arrived at the destination Benno. Osiris-Rex expects to spend a month carefully drawing Benzu's full surface site and then selecting a template sample by the scientist. Once this place is determined, Osiris-Rex will slowly approach Bennu, and when it is about to hit, use the high-pressure gas tank at the front of the arm to "spray" the surface and bubble the particles of the surface to the Collector at the front end of the arm. Finally, Osiris-Rex will store the samples and then set sail back to Earth in 2021. It is expected that in 2023, the samples will be placed in a special insulated cabin and returned to the ground's atmosphere.

In addition to Osiris-Rex, Japan's Jaaxa Hayabusa 2 Detector is also performing similar tasks on the aspirin revenues, but Haila's collection method is much more "violent," using a 2.5 kg copper rod straight. Rushing to the surface of Rivhu, after a pit of about 2 meters wide, blown up, Hayabusa goes down to collect the dust particles. Compared to Osiris-Rex, Hayabusa should be able to get deeper samples that are not affected by the cosmic environment. However, it is still difficult to collect samples and return to the ground. Both the first genesis and the first genus of Hiaubusa were failing, and the stardom mission to collect only the comet end was successful.

In other aerospace news, the Soyuz mission, which was previously different due to the bending of the sensor pins, finally successfully sent the three astronauts to the International Space Station, and avoided the dilemma that the space station might be "annoyed." On the other hand, SpaceX is scheduled to launch rockets again after a brief interval, this time for the NASA CRS-16 space station replenishment mission. If all goes well, it is expected that the local time will be around 2:30 in the morning, this time using a brand new subordinate rocket.
