Mar 19, 2021 The asteroid, officially known by NASA as 231937, is smaller than the last notable one to closely approach Earth, but it will be three times closer, NASA said in a statement. NASA Analysis: Earth Is Safe From Asteroid Apophis for 100-Plus Years 2021-03-25. After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.

How do we spot near-Earth asteroids?

To start, survey telescopes scan the sky.

When multiple pictures of the same spot show a spec that's moving, computers automatically check it against a database of known objects.

If there's no match, it gets added to a list of objects to confirm.

And if it looks like it will pass very close to us, we give it top priority.

Then it's time to call in for reinforcement: More astronomers from NASA, other institutions and even the amateur community submit additional observations.

Each new data point helps refine the projected path.

And this asteroid is going to fly right on by.

All the info will be posted online so it can continue to be tracked and monitored.

Nice work planetary defense team! Keep watching the skies.

NASA's OSIRIS-REx asteroid probe will attempt to collect samples of asteroid Bennu today Tuesday (Oct. 20) and you can watch it live here.

OSIRIS-REx launched to asteroid Bennu in 2016 as NASA's first asteroid sample-return mission. The spacecraft arrived at Bennu in 2018 and is expected to return its samples to Earth in 2023. First, OSIRIS-REx must collect Bennu samples. That begins today with its first 'tag' maneuver.

NASA's webcast will begin at 5 p.m. EDT (2100 GMT) and cover OSIRIS-REx's sampling attempt at 6:13 p.m. EDT (2213 GMT). The webcast will end at 6:30 p.m. EDT (2230 GMT).

Starting at 1 p.m. EDT (1700 GMT), you can following OSIRIS-REx's approach to Bennu live with a real-time animation at the mission's website here.

From NASA:

Editor's Note: This advisory was updated on Monday, Oct. 19, to reflect programming changes for Monday, Nov. 19.

NASA will broadcast coverage of a first for the agency as its Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission attempts to collect a sample of asteroid Bennu on Tuesday, Oct. 20, at 6:12 p.m. EDT.

Live coverage of the spacecraft’s descent to the asteroid’s surface for its “Touch-And-Go,” or TAG, maneuver, which will be managed by Lockheed Martin Space near Denver, will begin at 5 p.m. on NASA Television and the agency’s website.

Beginning with an orbit departure maneuver around 1:50 p.m., the full sequence of the complicated engineering feat will be covered on @OSIRISREx, and media and the public can ask questions using the hashtag #ToBennuandBack.

In addition to the broadcast Tuesday, Oct. 20, briefings and social media activities will cover the mission and asteroid science on Monday, Oct. 19.

OSIRIS-REx, which is about the size of a 15-passenger van, is currently orbiting the asteroid Bennu 200 million miles from Earth. Bennu contains material from the early solar system and may contain the molecular precursors to life and Earth’s oceans. The asteroid is about as tall as the Empire State Building and could potentially threaten Earth late in the next century, with a 1‐in‐2,700 chance of impacting our planet during one of its close approaches. OSIRIS-REx is now ready to take a sample of this ancient relic of our solar system and bring its stories and secrets home to Earth.
