Is there such as thing as too much asteroid?
Scientists and engineers for NASA’s OSIRIS-REx decided to perform an “early stow” of the sample from Asteroid Bennu collected by the spacecraft on October 20, because the collection container is full-to-overflowing, possibly jamming the collector head from sealing shut.

Out in the asteroid belt, 207 million miles (334 million km) from Earth, a little spacecraft briefly touched down on the surface of Asteroid Bennu today, attempting to collect samples of dust and rocks.
NASA’s OSIRIS-REx spacecraft (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) spent about 10 seconds on the ancient asteroid to collect samples, slated to come back to Earth in 2023. While mission scientists and engineers need to confirm that samples from the asteroid were collected, preliminary data show that every step of the procedure went as planned.

Today’s the day! The OSIRIS-REx spacecraft is going to reach out and boop asteroid Bennu! You can watch the broadcast here as the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission attempts to collect a sample of an asteroid on Tuesday, Oct. 20, at 6:12 pm EDT (5:12 pm CDT, 3:12 PDT).

NASA is about to achieve another first for their organization. In about three weeks time, on October 20th, the OSIRIS-REx spacecraft will descend to Bennu’s surface, briefly touch down, and collect a sample from the asteroid. The spacecraft will collect a minimum of 60 grams (2 oz.) of material for return to Earth.

Is it a new asteroid mini–moon or a human-made mini-moon? That’s the question about a small object approaching Earth, called 2020 SO. NASA’s Small Body Database predicts the object will captured by Earth’s gravity in October 2020 and temporarily be trapped in orbit.

In an expected move, the Japan Aerospace Exploration Agency (JAXA) has announced a mission extension for their Hayabusa2 spacecraft. Hayabusa2 will be sent to rendezvous with another asteroid in a few years time.
It’s target is 1998 KY26, a near-Earth object (NEO) less than a kilometer in diameter. But it’ll take a while and some maneuvering around other objects in the Solar System to reach its goal. JAXA says the spacecraft will arrive at the asteroid in July 2031.

Does it seem like science is catching up with science fiction? Sometimes it does. Especially when there’s an announcement like this one.
A Chinese company says that they’ll be launching an asteroid-mining robot by November.

Astronomers have painstakingly built models of the asteroid population, and those models predict that there will be ~1 km sized asteroids that orbit closer to the Sun than Venus does. The problem is, nobody’s been able to find one. Until now.
Astronomers working with the Zwicky Transient Facility say they’ve finally found one. But this one’s bigger, at about 2 km. If its existence can be confirmed, then asteroid population models may have to be updated.

As soon as the OSIRIS-REx spacecraft arrived at asteroid Bennu in December 2018, there was a big surprise. Scientists expected Bennu’s surface would consist of fine-grained material like a sandy beach. But take a look at that surface: Bennu is a jumbled mess.
Here’s a closer view:

This summer, the European Space Agency’s Near-Earth Object Coordination Centre (NEOCC) started posting “riddles” or challenges on their website. These riddles provide a look at how difficult it is for astronomers to find faint, near Earth objects (NEO). Try it for yourself by looking at the animation below:
