    This is the submarine that was being reported a year or so ago.

    But looks like it would have been a separate mission to this one.

    You are right. I missed that one.

    There are plenty of mission that need doing. I wish NASA could do more in that direction instead of wasting money on unsustainable boondoggles like SLS. But Congress holds the purse string and let's dance NASA on them.

    It seems what's holding them back id designing an adequate boat trailer to transport the craft to the lake.

    Wow.

    SpaceX released a video of the recent Falcon Heavy mission. The fairing reenters the atmosphere and SpaceX wants to recover the halves because they are really very expensive. They are ~$3million for each half, so 6million for the fairing, worth some effort to recover them. Though it is really difficult, they want to avoid picking them out of the water, if possible so they try to catch them in a net. Filmed by a camera inside the fairing. They added thrusters so they can determine the exact angle of reentry so they don't break up. They added parachutes for a smooth glide coming down.






    An older video of a fairing reentering but without recovery attempt a while back. This camera was recovered by chance on a beach. Crazy to think they even added the camera with nearly no chance of ever getting it back. I am sure I have posted this video already before but think it is a nice addition

    I saw that Nasa successfully tested the abort system of Orion. Which they plan to take men and a woman onto the surface of the moon in 2024.


    NASA reached an important stepping stone to a crewed mission to the Moon today, with a successful demonstration of the Orion spacecraft’s launch abort system.

    I thought all this "scrap" was meant to burn up on re-entry?

    Those fairings are tough. They are also not as fast as the orbital debris that mostly burn up. Fortunately all fairings launched from the US drop into the sea and are not dangerous that way. They sometimes wash up at beaches. One time a camera inside the fairing was recovered this way and we got this video:




    But SpaceX wants to actively recover and reuse fairings. These hulls are painfully expensive. Around $6million for one SpaceX fairing. So they stablize them that they can reenter undamaged. They had to put a steel cover at the tip. Seems that gets quite hot.

    Watch the video of the first successfully recovered fairing few posts above. Quite SF, a must see.

    Enjoy yourselves while you can, the universe is coming to an end.

    or not.


    Astronomers have spotted a distant pair of titanic black holes headed for a collision.


    Each black hole's mass is more than 800 million times that of our sun. As the two gradually draw closer together in a death spiral, they will begin sending gravitational waves rippling through space-time. Those cosmic ripples will join the as-yet-undetected background noise of gravitational waves from other supermassive black holes.

    But if quantum effects at a distance are real, then on some level they have affected/are affecting us now, as they already collided a couple of billion years ago, even though the gravity waves have not yet arrived....

    For you space heads, and i don't know if you can access it but Channel 4 in the UK has a programme "Moon Launch Live" on tonight at 8pm UK time. It relives the Apollo 11 mission, i apparently stayed up all night to watch it at the time.

    That was great, thanks for sharing.

    Once the Boys understand Rocket stages and all that I'll share and explain what's happening in the clip.

    They are really getting into it now. They can name all the Planets in order, know where some of the names are derived from and the names of the Dwarf Planets ... I thought there was just Pluto.

    We just bought the Glow in the Dark planets, about the size of dinner plates and stuck them on their bedroom wall.

    They were a bit sad to see the dinosaur and Pirate stickers to go though

    India aborts Chandrayaan-2 Moon mission launch less than an hour before lift-off

    Space News thread-11310192-3x2-940x627-jpg
    The Chandrayaan-2 mission vehicle at a launch pad.


    With less than an hour before lift-off, India has aborted the launch of a spacecraft intended to land on the far side of the Moon.

    Key points:

    • The Chandrayaan-2's mission was to make a soft landing on the lunar south pole and send a rover to explore water deposits
    • The countdown abruptly stopped at T-56 minutes, 24 seconds due to a "technical snag"
    • The Indian space agency will announce a revised launch date soon


    The Chandrayaan-2 mission was called off when a "technical snag" was observed in the 640-tonne, 14-storey rocket launcher, Indian Space Research Organisation spokesman BR Guruprasad said.

    The countdown abruptly stopped at T-56 minutes, 24 seconds.

    Mr Guruprasad said the agency would announce a revised launch date soon.
    Chandrayaan, the word for "moon craft" in Sanskrit, was designed to make a soft landing on the lunar south pole and send a rover to explore water deposits confirmed by a previous Indian space mission.

    With nuclear-armed India poised to become the world's fifth-largest economy, the ardently nationalist Government of Prime Minister Narendra Modi is eager to show off the country's prowess in security and technology.


    Rest is Here

    The chinese space station Tiangong 2 was actively deorbited and dropped into the South Pacific. That area is frequently used for deorbiting because it is so wide and empty.

    There was video footage of the reentry. You can see the glow of the heating high atmosphere until the camera was destroyed.

    I saw that in Gravity. That Sandra Bullock was bloody lucky if you ask me.

    Marvellous pictures. Worth seeing for the camera work. But for anybody who knows even very little about space and orbits a painfully idiotic story line.

    What kind of records was it? I am reading here that the backup tapes of the live landing were lost:

    https://en.wikipedia.org/wiki/Apollo_11_missing_tapes

    The Apollo 11 missing tapes were those that were recorded from Apollo 11's slow-scan television (SSTV) telecast in its raw format on telemetry data tape at the time of the first Moon landing in 1969 and subsequently lost. The data tapes were recorded as a backup in case the live television broadcasts failed for any reason.

    To broadcast the SSTV transmission on standard television, NASA ground receiving stations performed real-time scan conversion to the NTSC television format. The moonwalk's converted video signal was broadcast live around the world on July 21, 1969 (2:56 UTC). At the time, the NTSC broadcast was recorded on many videotapes and kinescope films. Many of these low-quality recordings remain intact. As the real-time broadcast worked and was widely recorded, preservation of the backup video was not deemed a priority in the years immediately following the mission.[1] In the early 1980s, NASA's Landsat program was facing a severe data tape shortage and it is likely the tapes were erased and reused at this time.[2]

    A team of retired NASA employees and contractors tried to find the tapes in the early 2000s but was unable to do so. The search was sparked when several still photographs appeared in the late 1990s that showed the visually superior raw SSTV transmission on ground-station monitors. The research team conducted a multi-year investigation in the hopes of finding the most pristine and detailed video images of the moonwalk. If copies of the original SSTV format tapes were to be found, more modern digital technology could make a higher-quality conversion, yielding better images than those originally seen. The researchers concluded that the tapes containing the raw unprocessed Apollo 11 SSTV signal were erased and reused by NASA in the early 1980s, following standard procedure at the time.[3][1][4]

    Although the researchers never found the telemetry tapes, they did discover the best visual quality NTSC videotapes as well as Super 8 movie film taken of a video monitor in Australia, showing the SSTV transmission before it was converted. These visual elements were processed in 2009, as part of a NASA-approved restoration project of the first moonwalk. At a 2009 news conference in Washington, D.C., the research team released its findings regarding the tapes' disappearance. They also partially released newly enhanced footage obtained during the search. Lowry Digital completed the full moonwalk restoration project in late 2009.

    Asteroid 2019 OD to flyby Earth at 0.93 LD on July 24 - the largest of the year




    A newly discovered asteroid designated 2019 OD will flyby Earth at a distance of 0.93 LD / 0.00239 AU (357 538 km / 222 164 miles) on July 24, 2019. This is the 31st known asteroid to flyby Earth within 1 lunar distance since the start of the year and the largest.

    2019 DO is an Apollo-class asteroid first observed at ATLAS-HKO, Haleakala, Hawaii on July 21, three days before close approach.


    Its estimated diameter is between 52 and 102 m (170 - 334 feet), making it the largest <1LD asteroid of the year so far.


    The object will fly past us at a speed (relative to the Earth) of 19.17 km/s at 13:31 UTC

    The CRS-18 mission, resupply of the ISS is going to launch tomorrow.

    Falcon 9 static fire test complete — targeting July 24 launch from Pad 40 in Florida for Dragon’s eighteenth resupply mission to the @Space_Station


    This launch brings a very important piece of equipment. The second IDA docking adapter. One is already installed but for regular service of crew flights to the ISS by Boeing and SpaceX they need two adapters. One was lost on the failed CRS-7 launch.

    The IDA adapter packed in the Dragon trunk.

    Space News thread-ida-jpg

    The Falcon 9 booster has flown before. The Dragon capsule does its third flight. Dragon capsules are no longer produced. They need to reuse existing capsules. All available have flown twice already. All launches from now on will be third uses. Including CRS-18 there will be 3 more launches in this contract. After that there will be a new contract and the capsule type will be the one developed for Commercial Crew.
