Japan's Hayabusa 2 probe has
0:03
successfully flown past an asteroid in a
0:06
test aimed at assessing whether a
0:09
spacecraft could one day be used to
0:11
alter the course of an asteroid
0:14
threatening Earth. It is the second
0:16
successful experiment of its kind
0:19
following NASA's DART mission in 2022,
0:22
our correspondents in Japan report.
0:29
>> Hayabusa 2 was traveling at around
0:31
18,000 km per hour when it passed within
0:35
800 m of the asteroid Toryfune.
0:37
According to the Japan Aerospace
0:39
Exploration Agency, JAXA, spacecraft
0:43
from other countries have previously
0:44
carried out similar flybys.
0:47
But they generally observe their targets
0:49
by telescope from distances of more than
0:52
100 km.
0:56
>> This technique requires the probe to
0:58
approach the asteroid with extremely
1:01
high precision. I believe it is
1:02
important to refine this kind of
1:04
technology so that it is ready when
1:06
needed.
1:11
>> Hayabusa 2 used its onboard camera to
1:14
photograph the asteroid Toryfune while
1:17
gathering data with a range of sensors
1:19
and automatically making decisions to
1:22
adjust its own flight path.
1:24
The flyby was designed to avoid any
1:27
collision.
1:30
>> To be honest, I never thought we would
1:32
be able to capture an image like this. I
1:35
am absolutely delighted. I would like to
1:37
thank the research team for all their
1:39
efforts.
1:41
>> In 2022, NASA successfully altered the
1:44
orbit of an asteroid by crashing its
1:46
DART spacecraft into it.
1:48
The latest Hayabusa 2 experiment has
1:51
added close-range observation
1:52
capabilities, which could help inform
1:55
future efforts to deflect asteroids from
1:57
their course.
1:59
Compared to approach missions, an
2:01
asteroid flyby happens in just an
2:03
instant, and the scientific data
2:05
collected is also limited. However, it
2:08
allows for experiments to design a
2:09
collision mission to deflect an asteroid
2:12
and protect the Earth.
