Welcome to Astronomy Daily for the 29th of May 2023. We've got some interesting things for you this afternoon
00:00:06
or this evening or this morning where you might be catching us. We're going to be talking about
00:00:12
NASA's interesting influences on our daily life, some interesting inventions and developments that they've dumped on us over the years
00:00:21
as well as something that China has been developing and has been flying over our heads for the last nine months.
00:00:27
Interesting and strange.
00:00:29
Yes indeed, I'm Ziohoes Steve Dunkley for this afternoon. Would you welcome
00:00:41
Halle our digital reporter? Hi Halle. Hi Steve. Did you find some interesting stories for us today?
00:00:47
Yes, let's get into it.
00:00:54
An asteroid that may host life's building blocks will get a visit from a United Arab Emirates spacecraft about a decade from now, if all goes according to plan.
00:01:03
In October 2021, the UAE announced that it plans to launch an ambitious mission to the asteroid belt in 2028.
00:01:12
That mission will visit seven different space rocks and even land on one of them, an asteroid called 269 Justisha.
00:01:21
Sheikh Muhammad bin Rashid Al-Makhtum bin Rashid Al-Makhtum, the vice president and prime minister of the UAE and the ruler of Dubai, said in a statement that we will never cease to look ahead.
00:01:33
We will never cease our efforts to develop a brighter future for our young generations.
00:01:38
The EMA spacecraft will be named after the Sheik. It will be called the MBR Explorer and will visit its first asteroid in 2030
00:01:47
and will follow an orbital path allowing it to pick up speed from several planets along the way.
00:01:52
It's common for spacecraft to get such a gravity assists from worlds like Venus or Mars to save on fuel
00:02:00
and to do side observations to test their instruments.
00:02:03
After passing by six asteroids, the mission aims to touch down upon Justisha in 2034 with a small lander that it deploy.
00:02:12
Justisha may have organic molecules on its surface, organics are the building blocks of the complex molecules that could form life in the right circumstances.
00:02:24
The Airbus-built Arab-Sat-Bad-8 telecommunications satellite has been successfully launched from Cape Canaveral of Florida.
00:02:32
Based on Airbus latest geostationary Eurostar Neo-Satellite, Bad-8 will provide connectivity for users across Europe, Middle East, Africa, and Central Asia.
00:02:45
The spacecraft is also equipped with a world first, Airbus Innovative Space Demonstrator Tiliot to provide space to ground optical communications at Gigabit speeds.
00:02:56
The Tiliot Demonstrator payload is designed to facilitate very high-capacity optical feeder link communications,
00:03:03
playing a crucial role in Airbus development of a new generation of optical communications technology in space.
00:03:11
Featuring increased payload capacity and more efficient power and thermal control systems,
00:03:16
Bad-8 will replace and increase Arab-Sat's capacity.
00:03:22
I was wondering when we were going to see some new lunar vehicles. Here we go, Steve.
00:03:27
NASA is seeking industry proposals for a next-generation LTV lunar terrain vehicle.
00:03:34
That will allow astronauts to go farther and conduct more science than ever before as they explore the South Polar Region of the Moon, during Artemis missions.
00:03:44
Artemis astronauts will drive to explore and sample more of the lunar surface using the LTV than they could on foot.
00:03:52
NASA will contract LTV as a service from industry rather than owning the rover.
00:03:58
Contracting services from industry partners allows NASA to leverage commercial innovation and provide the best value to US taxpayers,
00:04:06
while achieving its human spaceflight scientific and exploration goals.
00:04:12
We want to leverage industry's knowledge and innovation, combined with NASA's history of successfully operating rovers,
00:04:19
to make the best possible surface rover for our astronaut crews and scientific researchers,
00:04:24
said Laura Kerney, manager of NASA's Extr-Vhicular Activity and Human Surface Mobility Program at the agency's Johnson Space Center, in Houston.
00:04:35
The LTV will function like a cross between an Apollo-style lunar rover and a Mars-style uncrude rover.
00:04:42
It will support phases driven by astronauts and phases as an uncrude mobile science exploration platform,
00:04:49
similar to NASA's Curiosity and Perseverance Mars Rovers.
00:04:53
This will enable continued performance of science even when crews are not present on the lunar surface.
00:05:00
Artemis astronauts will use the LTV to traverse the lunar surface and transport scientific equipment,
00:05:06
extending the distances they can cover on each moonwalk.
00:05:10
And that's the short takes for today.
00:05:13
Have you got something interesting and weird to share Steve?
00:05:23
Yes, I did find a couple of interesting stories and this one involves the kinds of things that NASA
00:05:29
have developed over the years and brought into our lives.
00:05:32
I don't know why they're releasing this information.
00:05:34
At the moment, I think they're trying to play catch-up with all of the millionaires out there making such wonderful headlines.
00:05:40
Let's have a look at what they're saying.
00:05:41
Now, although basic water filters had been in existence since the 1950s,
00:05:47
it wasn't until NASA pumped resources into the research for the Apollo program.
00:05:53
In 1963, modern filtration systems began to emerge and NASA led research into this area as large quantities of water,
00:06:02
they say, would need to be kept uncontaminated for long periods of time.
00:06:07
I wonder what they were planning.
00:06:08
And they needed to keep them clean in extreme conditions.
00:06:12
NASA developed a system that worked by utilizing charcoal's ability to absorb
00:06:19
pollutants and particulate matter present within the water when specially treated.
00:06:24
And while technically, NASA didn't invent the integrated circuit, which is credited to electrical engineer Jack Kirby in 1958,
00:06:32
NASA did give us smaller and more advanced versions of it.
00:06:35
It's often said that NASA kickstarted the microchip-dare revolution by
00:06:40
buying more than 60% of America's integrated circuits throughout the 60s,
00:06:44
essentially causing the industry to go into a state of mass production while few other markets existed.
00:06:50
Now, these chips were destined for use as part of the navigation guidance computer systems aboard the Apollo
00:06:57
and the command and lunar modules.
00:06:59
Now, let's talk about one of our favorite subjects, Crash Helmets.
00:07:05
NASA's development of Temporphone, foam, a shock absorbing material designed for use in various
00:07:12
aircraft cushions, was also used in helmets and seats of Apollo spacecraft and helped to mitigate
00:07:18
the extreme forces the astronauts were subjected to. Temporphone was released to the public sphere in the early 1980s,
00:07:26
soon being picked up and utilized in medical equipment such as Temporphone mattresses and sports equipment,
00:07:33
such as football helmets and, of course, motorcycle helmets.
00:07:40
Now, one notable breakthrough was NASA's collaboration with a tool company, Black Endecker,
00:07:47
now who would have guessed it? Into a cordless zero impact wrench, a tool that could spin bolts
00:07:53
in zero gravity, presumably without spinning the astronaut in the other direction.
00:07:59
The research program developed a cordless tool or a variety of tools for a variety of purposes,
00:08:06
including a cordless rotary hammer drill that could be used for extracting rock from the moon surface.
00:08:13
These days, its tech is common and widespread with the many tools being cordless running from a recharge
00:08:19
of battery. Interestingly, it was directly from the research done by NASA in the 1960s that Black Endecker
00:08:26
developed a cordless dustbuster handheld vacuum cleaner now who hasn't owned one of those.
00:08:32
I just wonder whether or not yours worked any better than mine did.
00:08:36
Anyone with eye glasses will appreciate this little one. It's due to NASA's research
00:08:42
that space visors are now coated with diamond-like carbon coatings that are applied in thin films
00:08:51
to the outside of the visor and toughen it. An offshoot of this technology is available on RayBan
00:08:57
sunglasses, while Foster Grant historically bought the license to replicate early coatings to apply
00:09:03
to its entire range. And while smoke detectors had been invented by Francis Robbins Opton in 1890,
00:09:11
they were digestible until NASA invented a model with variable sensitivity in 1973.
00:09:18
The units were installed on Skylab to detect toxic vapors on board. I wonder if they were going off.
00:09:26
Well, Skylab was coming down. A couple more include a dimpled surface,
00:09:32
similar to that of a golf ball, on the shuttle's external fuel tank, allowing for a more
00:09:38
efficient lift to drag ratio in flight. So if we ever do see our flying cars,
00:09:42
maybe they should have a dimpled surface as well. Revamped multifunctional joysticks for lunar modules
00:09:51
and land aerovers allowed for greater control of the vehicles utilizing a simple control system
00:09:57
and who wouldn't want one of those. Now China has finally brought its mysterious space plane
00:10:04
back to Earth after a massive nine months in orbit. This is its second mission. Chinese
00:10:11
State News reported that the success of this mission is a significant breakthrough in our country's
00:10:17
research on reusable spacecraft technology. Unsurprisingly, the Chinese government has
00:10:23
remained quiet about the craft details of its design, its capabilities and performance.
00:10:29
Much actual information about the mysterious plate space plane is hazy.
00:10:33
Presently, there are experts who believe that the craft is much like the Boeing X-37B,
00:10:39
a US space plane that debuted in 2010. Kevin Polpeter, a research scientist at the Centre for
00:10:46
Naval Analysis said that the X-37B sparked concern within the Chinese government over the
00:10:52
craft's military potential. He said it's possible that this spurred the country space program,
00:10:58
which is tied to its military, to start developing its own version. In a similar vein to the Boeing
00:11:05
design, the Chinese space plane appears to be an unmanned vehicle and relatively small. It resembles a
00:11:12
twin-tailed space shuttle style craft, but the further details are difficult to discern. It
00:11:18
probably flew first in September 2020, making a short two-day stint into orbit, probably a test.
00:11:25
It's most recent mission began in August 2022 when it took off on a long march to air
00:11:33
rocket from northern China, the exact purpose of that mission remains unclear. According to
00:11:39
the Centre for Strategic and International Studies report, the craft released an object into orbit
00:11:45
sometime in October. The object apparently disappeared in January only to suddenly reappear on
00:11:52
satellite tracking radar in March. Experts believe that this could indicate that the plane has some
00:11:58
sort of satellite removal capability, such as a robotic arm. If that's the case, then the plane's
00:12:04
primary purpose might be to repair damaged satellites or remove orbital debris. However,
00:12:10
this does not rule out military capabilities, either for the Chinese space plane or for the
00:12:15
X-37B. Until more details come out, however, the best we can do is speculate.
00:12:21
