On December 5th, 2020, the Japanese Aerospace Exploration Agency’s (JAXA) Hayabusa 2 mission sent a sample capsule home containing debris from the near-Earth asteroid (NEA) 162173 Ryugu. This was the culmination of the probe’s first six years in space, which launched in Dec. 2014 and rendezvoused with Ryugu in June 2018. While the probe sets its sights on its new targets, scientists will be busy analyzing the Ryugu sample.
One thing they noticed immediately after opening the shell on Monday (Dec. 21st) was the black sandy dust that lined the capsule’s outer shell. According to a statement issued by JAXA, the black sand is material taken from the surface of Ryugu. Considering what’s inside sample chamber A, it appears that the amount of material obtained by Hayabusa 2 is more substantial than previously thought.
In October of 2024, NASA will send astronauts to the Moon for the first time since the Apollo Era. After establishing orbit with their Orion spacecraft, a team of two astronauts (“the first woman and the next man”) will land in the Moon’s southern polar region. Over the course of a week, these astronauts will explore and investigate one of the region’s many permanently-shadowed craters.
As the first crewed lunar mission in over fifty years, this mission and those that follow will have a robust series of science objectives. These objectives were laid out in the Artemis III Science Definition Team Report, which was released to the public earlier this month. This report is a summary of the science plan prepared at the behest of NASA’s Science Mission Directorate (SMD) for the Artemis III mission.
For the first time in more than 40 years, a robotic spacecraft has blasted off from the Moon – and for the first time ever, it’s a Chinese spacecraft, carrying precious lunar samples back to Earth.
The ascent vehicle for the Chang’e-5 mission fired its engine and rose a region called Oceanus Procellarum at 1510 UTC (11:10 p.m. Beijing time) on December 3rd, the China National Space Administration’s China Lunar Exploration Project reported.
Imagery sent back from the Moon provided a view of the blastoff from ground zero. It was the first successful lunar launch since the Soviet Luna 24 probe took off during a sample return mission in 1976.
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).
The asteroid belt is a chaotic place. Things smash into each other, get thrown into completely different orbital planes, and are occasionally visited by small electronic spacecraft launched by humans. All three things seem to have happened to the asteroid Bennu, which is currently being orbited by OSIRIS-REx, a mission launched by NASA in 2016.
The most recently released results from the mission show that Bennu might have small pieces of Vesta on it. Given that Vesta is one of the biggest asteroid belt objects and Bennu is a near Earth asteroid millions of kilometers away from the asteroid belt, this hints at a pretty exciting past history for the asteroid currently being visited by NASA’s first asteroid sample return mission.
Every 26 months, the orbits of both Earth and Mars conspire to make travel between the two planets shorter. Launching in one of these windows means the travel time can be reduced to only six months. Our robotic missions to the Martian surface, and missions that place satellites in Martian orbit, launch during these windows.
But are there other alternatives to this mission architecture?
One group of researchers says that crewed missions to Mars shouldn’t go directly to their destination; they should slingshot past Venus first.
The date is finally set for OSIRIS-REx’s sampling maneuver. The spacecraft has been at asteroid Bennu since the end of December 2018. During that time, it’s found a few surprises, and mapped the surface in great detail.
Now, we can circle October 20th on our calendars, as the date OSIRIS-Rex will collect its sample.
NASA’s OSIRIS-REx spacecraft is getting ready for its big moment. OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is at asteroid Bennu, preparing to collect a sample of ancient rock. And collecting that sample means taking step after meticulous step.
In the near future, sample-return missions from Mars will finally be a reality. For decades, scientists have analyzed the composition of Martian rocks and soil by either sending rovers to the surface or by examining meteorites that came from Mars. But with missions like Perseverance, which are equipped with a sample cache instrument, it won’t be long before Martian rocks are brought back to Earth for study.
Similar to how the Apollo astronauts brought back Moon rocks, which revealed the existence of water on the Moon and its similarity to Earth, Martian rocks could reveal a great deal about the formation and evolution of the Red Planet. The question is, what rocks should be returned? This is the question that the international Mars Sample Return campaign is considering on the eve of Perseverance’s launch.
When the NASA spacecraft first arrived at asteroid Bennu over a year ago, the surface of the asteroid was much different than expected. Instead of a surface with large, smooth areas, nearly the entire surface is covered in boulders. That meant that NASA had to do a re-think of the sampling procedure.
