China has selected a Russian science payload to fly on an upcoming mission to sample a near-Earth asteroid and later visit a main-belt comet .
China is aiming to launch the ambitious mission around 2024. First, it will collect samples from the small near-Earth asteroid Kamo'oalewa. Then, the spacecraft will return to Earth to deliver the samples and use the planet's gravity to send the spacecraft toward the main asteroid belt to orbit the Comet 133P/Elst–Pizarro.

Spacecraft leaves mess after grabbing asteroid samples
CAPE CANAVERAL, Fla. – A NASA spacecraft left a mess at an asteroid when it grabbed a load of rubble last year for return to Earth, new pictures revealed Thursday.
The Osiris-Rex spacecraft made one final flyby of asteroid Bennu on April 7 to take photos of the disturbance left by October’s sample collection.
A depression is visible where Osiris-Rex penetrated the asteroid’s surface. Boulders were hurled by the pressurized nitrogen gas that was fired at the ground to churn up material for vacuuming, and by the spacecraft’s getaway thruster. One 1-ton boulder was flung an estimated 40 feet.
NASA: A spacecraft from asteroid to Earth ... shocking scene
To begin the journey to Earth, a spacecraft must be lifted from the asteroid. Before I knew it … Suddenly something happened there. Suddenly a commotion and confusion ensued. Not sure what actually happened there. The details of the incident that took place on April 7 last year were discovered by NASA scientists last Thursday with some photos.
This is what the scientists say … when the spacecraft crashed into the asteroid … it put a lot of pressure. Before the spacecraft lands … the nitrogen gas is released strongly to keep the area smooth. With that gas pressure … the rocks there will go to the sides like mud. After all this, the spacecraft landed well. Scientists say something happened when he climbed to a height of 40 feet during the resurrection. Can’t say what happened.
What is the likelihood of an asteroid to hitting Earth? | Space Facts
Asteroids hold a special place in the imaginations of people. These celestial bodies have been the subject of awe and fear, with images of ancient asteroids raining down on dinosaurs coming to mind. Modern instruments allow us to observe these space-faring objects, and we have even come up with sophisticated methods to predict when an asteroid to hit earth will happen.
One of the most dangerous asteroids is Apophis, a near-Earth object, which means its orbit puts it in Earth's proximity. For Apophis, its orbit puts it at just 1.3 times the distance between the Earth and sun. ADVERTISEMENT
How are asteroids, space weather and space debris detected before they hit Earth? | Space
To make matters worse, the proliferation of human-made satellites has created a space hazard of its own, as the loads of orbiting debris have the potential to destroy other satellites.
In the U.S., tackling these threats is the responsibility of several organizations: Both NASA and the U.S. Space Force tracks space debris; the National Oceanic and Atmospheric Administration monitor “space weather"; and NASA's Planetary Defense Coordination Office coordinates the search for potentially hazardous asteroids and other near-Earth objects (NEOs).
If you Want to Move an Asteroid, you Need the Right Kind of Nuclear Explosion - Universe Today
Using nuclear devices to deflect or disrupt an asteroid. Sounds a bit crazy, no? Maybe a little too Hollywood? And yet, detonating nukes in space may be necessary someday for the sake of planetary defense. In order for this method to be effective, scientists need to work out all the particulars in advance. That means knowing how much force will be necessary depending on the mass and trajectory of the asteroid.
Their research is described in a study, titled “Impact of neutron energy on asteroid deflection performance,” which was recently featured in the journal Acta Astronautica . The team behind it was led by Lansing Horan IV and colleagues from the Air Force Institute of Technology (AFIT), who conducted the research as part of a collaboration with the Weapons and Complex Integration Principal Directorate at the LLNL.
Passing Asteroid Lights Up South Florida Sky – CBS Miami
MIAMI (CBSMiami) – A fireball streaking across the sky Monday night was seen from Tampa to the northwest Bahamas.
CBS4 Chief Meteorologist Craig Setzer said it looks like it was a very close pass of asteroid 2021 GW4. He said it was likely passing about 9,000 miles above us and briefly struck the atmosphere while moving at 16,000 mph.
He added it literally passed inside the moon’s orbit which is about 252,000 miles away from Earth.

Space experts will come together this month to devise a plan for if an asteroid ever smashes into Earth, with experts warning it's not just the initial impact we need to prepare for but a series of human rights crises that could ensue.
The upcoming Planetary Defense Conference, which will be held in Vienna from April 26 - 30, will see space experts grapple with what to do should a foreign body ever actually come close enough to pose a danger to Earth.
Inverse Daily: A near-Earth asteroid and a raw imagining from the Late Pleistocene
Before we jump into four essential reads for your Friday morning, I wanted to firstly promote this powerful, compelling essay from Ben Ashwell that we just published.
It's called " It's time for men to start talking about male infertility. I'll go first ." I know I proudly say all our stories are must-reads, but this one especially falls into that category.
