    Remarkable footage of SLS launch from Everyday Astronaut. Been following these guys, they livestream a lot of the launches in the US. Just a bunch of guys, started out really small, but recently bought a retired NBC field reporting van to travel the country. Some of the high resolution footage is incredible.

    Watched the livestream. I would happily volunteer to be on the next trip. But that's just me.

    I did too! Late night for sure, but just had to watch it live. History in the making!

    One of those angles revealed what would happen very quickly if they have a slow gantry retract... not sure I would like to find out what happens if it hits the vehicle.

    It was 17 years from concept to first flight for the space shuttle, and that was just to test the orbiter on the back of a 747... It took another 5 to get it vertical for a launch.

    The little company that I've been working for this year has been involved with the Artemis project from the beginning. It's kind of neat to know some of their products are on the way to the moon

    Its almost comet time

    At the start of 2023 Earth will be visited by a newly discovered comet that may just be bright enough to be spotted with the naked eye.

    The comet, named C/2022 E3 (ZTF), is currently passing through the inner solar system. It will make its closest approach to the sun, or perihelion, on Jan. 12, and will then whip past Earth making its closest passage of our planet, its perigee, between Feb. 1 and Feb. 2.

    If the comet continues to brighten as it currently is, it could be visible in dark skies with the naked eye. This is difficult to predict for comets, but even if C/2022 E3 (ZTF) does fade it should still be visible with binoculars or a telescope for a number of days around its close approach.

    I found this quite amazing. https://space.com/dark-energy-camera-milky-way-survey

    Think of it as a portrait of the Milky Way where over 3 BILLION objects are individually recognizable. Think about that. One galaxy. Sure, we're alone out here.

    12:34 am Thursday try number 2 for the manned crew going to the ISS. First try went to the 2 minute mark before the scrub.....1,000's of people in town for the launch and its Daytona Bike Week this weekend.

    Relativity Space sets launch of world's 1st 3D-printed rocket for March 8
    We will be on the lagoon watching this history making launch.....
    The 3D-printed Terran 1 rocket from Relativity Space will fly from Florida's space coast, and will also mark the first natural liquid natural gas booster in space if all goes to plan. Should be a good show....

    Mars in 45 days, instead of 7 months?

    yuufd3048a3w.png

    As part of the NASA Innovative Advanced Concepts (NIAC) program for 2023, NASA selected a nuclear concept for Phase I development. This new class of bimodal nuclear propulsion system uses a "wave rotor topping cycle" and could reduce transit times to Mars to just 45 days.

    I hope they thought about brakes! Hehe...

    They should be more concerned about hitting objects at warp speed. A marble size object at 186,000 fps would take all the fun out of a trip to Mars

    well - given that the mass of that marble sized object would be infinite at the speed of light, yeah... it'd be a bit of a bother.

    PS You know NASA's Mars expedition's gonna sideswipe Elon's Tesla roadster on its way out. :#

    EDIT: I thought I was being (characteristically) absurd. Look where Elon's roadster was on 6 Feb 2023.

    At the end of March on the 27th we will watch a few planets align in the sky

    Twilight time
    Interestingly, our first two planets are studies in contrast. One is the smallest planet (Mercury) and the other is the largest (Jupiter).

    Once you have found a proper viewing site, and with binoculars in hand, wait until approximately 20 to 25 minutes after the sun has set. And your viewing time is going to be short. Both planets will set beyond the horizon only 25 to 30 minutes later.

    Both planets will be shining brilliantly, Mercury will glow at magnitude -1.4, which is just a trifle dimmer than Sirius, the brightest star in the sky. Jupiter will appear even more dazzling at magnitude -2.1, which is twice as bright as Mercury. But what will make a sighting problematic will be that both may be very difficult to see through the bright evening twilight.

    And that's where your binoculars come in.

    Your best chance to pick both planets up is initially to slowly sweep low along the western horizon with the binoculars; then after you hopefully have found them, seek them out with your naked eye. Mercury will be to the right of brighter Jupiter. On the evening of March 27, they will be separated by just 1.3 degrees (just over one-finger width at arm's length.)

    If you sight them, congratulate yourself. It is no mean feat to catch two planets positioned so close to the setting sun. Within just a day or two, Jupiter will disappear from view into the glare of the sun. Mercury, on the other hand, will be moving away from the sun's vicinity and will become a bit easier to see during the next couple of weeks.

    Evening Beacon
    In contrast to Mercury and Jupiter, the third planet on our list will be very easy to see: dazzling Venus, the so-called "Evening Star" (although "Evening Beacon might be a better term). It's the first planet to look for when the sun goes down. Venus is becoming increasingly prominent as it slowly gets higher in our western evening sky with each passing night. Right now, it's setting around 10:15 p.m. local daylight time. But two months from now, Venus will be noticeably higher in the west-northwest sky about an hour after sunset, and not setting until close to midnight.

    A planet racing away
    The fourth planet on our list is Mars. Several months ago, Mars shone brilliantly because it was relatively close to Earth; back on Nov. 30 it was 50.6 million miles away from us and appeared like a very bright fiery hued star, shining with a steady glow. A week later, like two racing cars going around on a track, we passed Mars in our respective orbits — Earth on the inside and Mars on the outside. And ever since then, we've left Mars far behind — in our side view mirror, preverbally speaking.

    On March 27, Mars will be 131.4 million miles (211.4 million km) from Earth — more than 2.5 times more distant than it was late last fall. It has correspondingly faded, appearing only 1/13th as bright compared to early in December. Yet it is still fairly conspicuous because it still ranks among the 21 brightest stars in terms of brightness.

    And you can make an instant identification of it, by simply looking up at our fifth celestial object of the evening, the moon. On this night, our natural satellite will resemble a fat crescent phase. And if you look off to the moon's upper left, that bright yellow-orange "star" will be Mars.

    Have a Life Saver!
    Now, use the binoculars again, and look just off to the left of Mars and you'll catch sight of M35, a star cluster in the constellation of Gemini the Twins. It ranked fifth among my list of personal deep-sky favorites in the wintertime sky. Long-time deep-sky columnist for Sky & Telescope, Walter Scott Houston wrote:(opens in new tab) "I feel that M35 is one of the greatest objects in the heavens. Observers with small telescopes will find it a superb object. The cluster appears as big as the moon and fills the eyepiece with a glitter of bright stars from center to edge. With 15x65 binoculars it was like a fat Life Savers candy, all white and glistening."

    Seventh planet from the sun
    Our fifth and final planet is the next-to-last out from the sun: Uranus.

    Barely visible to the unaided eye on very dark, clear nights, use Venus as a benchmark to find it. On Monday it will be just three degrees — roughly equal to one-third of the width of your clenched fist held at arm's length — to the upper left of that dazzling planet. Again, use your binoculars to scan this region of the sky. What you'll be looking for is a faint star, but the tipoff will be its pale greenish tint. That will be the third largest planet and next to the planet Neptune, the most distant planet from the sun.

    There you have it: five planets, a famous star cluster and the moon. Think you'll be able to sight all seven? As we've noted, a few will be easy but others will be more difficult. If skies are clear Monday evening, good luck and good hunting!
