Hey brother does this month.
00:01
Feel long to you a little bit.
00:03
Yeah, that's because it is,
00:05
this year is officially leap year,
00:08
which I don't, I don't know what the hell that means
00:11
But we know someone who does Jose Hernandez,
00:16
an astronaut, an author.
00:18
And there was actually a movie on his life that came out
00:21
last year, a million miles away.
00:23
He is the father who inspired our very own show,
00:27
astronaut's daughter. He is actually overqualified to talk about the silly
00:32
topic. Welcome, Jose.
00:34
Good morning Jenny. How you doing?
00:36
Good, good. And yourself?
00:39
I'm doing very well.
00:40
Thank you. It's great to have you.
00:42
I wanted to ask,
00:43
can you explain why we have leap year?
00:46
Like we're 1/5 grader because I have like we're kids because I
00:50
have no idea. I've never known all my life.
00:52
So I wanna, I wanna know as you know,
00:55
when we go, when we go through what year we
01:00
orbit around the sun,
01:01
that's approximately the time it takes to go around the sun once
01:07
is one year. This is how we have our four seasons
01:10
correct? And and I say approximately because guess what
01:14
it takes a little longer than one year to
01:19
go around.,
01:20
one year has 365 days.
01:23
But if, if you,
01:25
mark where the earth starts going around and when it
01:28
comes back, it's actually,
01:31
365 days.
01:33
0.2422. So a little over a day,
01:39
almost a quarter of a day.
01:41
So this is why we,
01:43
we have to,,
01:44
make up that day.
01:46
If not, that error air is gonna propagate and pretty soon
01:50
instead of having summer in June,
01:53
we're gonna be having summer in December and we don't want that
01:56
So what, what do we do to fix it?
01:58
Well, since it's about a quarter of a date,
02:01
each year, every fourth year,
02:05
we add a day to the calendar in February,
02:09
February 29th, which is this year,
02:12
we have a February 29th and that's how we get rid of
02:16
that extra quarter day for those four revolutions around the sun,
02:22
those four years. So every four years,
02:25
we have a February 29th.
02:27
So it's yeah,
02:28
it's like all the change that left over,
02:30
it adds up to a day.
02:31
But why February? Because that's the shortest,
02:34
this month of the year.
02:35
So we say let's add it to the shortest month of the
02:38
year. And it's,
02:39
it's great if you're born on February 29th because then you only
02:43
have to celebrate your birthday every four years.
02:46
So, if you're a 40 year old,
02:48
you're really 10 years old.
02:49
It's like, it's like dog years.
02:50
Right? Like dog years.
02:53
my dad,
02:54
my dad gets mad too because he has to pay the rent
02:56
for his business. So he's like,
02:57
no, it's those menu Diaz,
02:59
or he told me?
03:00
No, I, where's my change at?
03:03
Yeah. Yeah. The,
03:04
the,,
03:05
landlords make a killing on a monthly basis on the month of
03:09
of February because it's only 28 days.
03:12
But you still have to pay a full month.
03:13
Exactly. We lose.
03:15
But,, ok,
03:16
so while we have you,
03:18
what are your thoughts on the Odysseus mission?
03:22
why does that mean for the next generation of astronauts
03:25
we haven't been to back to the moon,
03:27
whether it's a rover or anything.
03:30
And I'm talking about the US United States since 1972 in December
03:35
Apollo 17.,
03:37
and,, and just recently a few days ago,
03:41
we landed a,
03:43
a lunar lander by a company called Intuitive Machines in Houston.
03:49
This company made up of ex NASA engineers built this
03:54
lunar lander and they launched it on a SpaceX falcon nine
04:00
rocket to the moon.
04:01
it landed almost perfectly.
04:04
It actually, instead of it,
04:06
let sticking the landing,
04:08
it kind of tipped over a bit.
04:10
And,, and so it's,
04:12
I would call it 90% success.
04:15
It's only designed to operate for a week or two.
04:19
But it's interesting to note that it wasn't NASA who returned
04:24
the US back to the surface of the moon,
04:27
but rather a private company intuitive machine.
04:30
And now we're gonna do another mission with intuitive machines and
04:34
we're gonna have another bigger payload.
04:37
And then after that,
04:38
we're gonna send a full size data center and start generating
04:44
revenue by having customers in an ultra secure repository for digital data
04:50
in the event of any type of disaster recovery needs.
04:53
They may have my company,
04:55
Tierra Luna Engineering is pioneering that effort with our customer
05:00
which is Lone Star data holdings.
05:02
Wow, that's so interesting.
05:03
And like, again,
05:03
the science of it all just like it was so like 90%
05:06
there. But again,
05:07
this is like only the star,
05:09
like you said, and where can people find to keep
05:11
up with all your missions?
05:12
And like, again,
05:13
all your consulting efforts?
05:14
Because again, like this is so interesting.
05:16
I wanna dive in deeper,
05:17
but I know you're,
05:18
you're a busy man.
05:18
So if you wanna plug your socials,
05:20
that'd be great. I would go to Tierra Luna engineering.com.
05:25
You can see what we do at Tierra Luna engineering.com,
05:28
but I also have my own line of wines.
05:31
You know, I grew up as a migrant farm worker
05:33
and there's a saying you can take the kid out of the
05:35
farm but not the farm out of the kid.
05:37
And and so I when I left NASA came back
05:41
home here in the central valley of California,
05:44
I decided to invest in a vineyard.
05:47
I make my own line of work called under the label,
05:51
Tierra Luna Sellers. I make two reds,
05:54
a, a red blend,
05:56
a red Zinfandel and then I make a whites blanc and
06:00
youtube can order it,
06:01
it comes to your house.
06:02
It's direct to consumers.
06:04
So it's it's there for you from space to the win
06:09
Thank you so much.
06:10
It's full circle. It's coming.
06:12
I literally thank you so much,
06:16
Jose. We really appreciate you coming on and we hope
06:20
you have a great leap year.
06:24
No problem. Thank you very much.
06:25
OK. Talk soon.
06:28
Bye. That's crazy.
06:31
Engineer. Everything he owns a vineyard.
06:34
The man could do it all.
06:35
Let's enjoy his extra day sister.
06:37
What do you say?
06:37
II, I agree,
06:39
brother. But I kind of feel like I've been stolen it
06:41
a day too. Porque Trin,
06:44
trin Trin Uno. I still feel like I don't know but
06:47
anyhoo, I get it.
