After a journey spanning over 96 kilometers, scientists now study fragments of an ancient
00:05
asteroid that could explain water's origin in our home planet.
00:10
V-Way's Arash Rabasadi has this story.
00:14
We begin this week with what could be the future for sustainable farming on Earth and
00:19
in space.
00:20
Paris and Los Angeles-based biotech company Interstellar Lab designed the BioPod.
00:26
The company's founder says BioPod allows farmers to localize the production of common
00:31
crops that would otherwise require global supply chains and therefore reduce greenhouse
00:36
gases that come with long journeys.
00:39
"Brewing vanilla, for instance, here, then this is when the BioPod makes a lot of sense.
00:44
And so it's reduced the CO2 impact of making the travel of the ingredients from one country
00:49
to the other.
00:50
We optimize the consumption of water.
00:53
So compared to traditional agriculture, it's like 99 percent of the water is recycled and
00:57
reused.
00:58
We take CO2 from the atmosphere to enrich the level of CO2 inside the bubble."
01:03
By stacking the units, Interstellar Lab says it can reduce the footprint for growers while
01:08
providing a more efficient space to grow crops in units that go up instead of out.
01:14
In collaboration with NASA, a space-based version of BioPod is scheduled for use on
01:18
the Moon by 2027.
01:21
The Reuters news agency reporting Interstellar Lab founder Barbara Balvisi will attend the
01:26
COP28 climate conference to raise interest and money for the project.
01:31
When commercial production begins, each unit will sell for $350,000.
01:37
In other news, the dust and fragments in these still images come from the 4.5 billion year
01:43
old asteroid Bennu.
01:46
NASA's OSIRIS-REx spacecraft collected the samples in October 2020.
01:51
After a journey of more than seven years, it landed at the Utah Test and Training Range
01:55
military facility.
01:57
Researchers say they found water trapped in the fragment, which may be a clue as to how
02:02
water came to Earth.
02:03
"When the Earth formed, it probably formed really, really hot and most of the water would
02:09
have evaporated.
02:10
So it could be that the Earth got its water because it was pummeled by asteroids like
02:15
Bennu that provided this water to the Earth's surface."
02:20
Russell added that Bennu is perhaps the most hazardous threat to Earth in our solar system,
02:25
so part of the research is to better understand its orbit and composition if scientists ever
02:31
had to find a way to deflect it.
02:33
Regardless, Russell says it will take months and years to unlock the many questions scientists
02:38
have about this ancient asteroid.
02:41
Finally this week, if you've ever had a rough day at the office, try losing your tool bag
02:46
in Earth's orbit outside the International Space Station.
02:50
That's what happened in early November when NASA astronauts Jasmine Mogbele and Laurel
02:55
O'Hara lost theirs.
02:57
The bag was visible with just binoculars and joined a long list of space junk orbiting
03:02
our planet.
