    Jezero Crater
    Hope it's not a double post

    The Jezero Crater on Mars was named after the earthly village of Jezero, Bosnia.
    The International Astronomical Union named Jezero Crater, the site of an ancient Martian lake, in 2007. The 28-mile long crater is located on the western edge of Isidis Planitia, a giant impact basin just north of the Martian equator, according to NASA.

    A composite. Curiosity takes photos of itself from many angles and the pictures are assembled into what we get to see. Curiosity has no helicopter, that's new with Perseverance and has not flown yet.

    They could commit the same idiocy as NASA and build a station in lunar orbit, then pretend it helps building base on the surface later.

    This will be interesting once probably tested.

    Rare meteorite that fell on UK driveway may contain 'ingredients for life'


    (CNN)A fireball that lit up the sky over the United Kingdom and Northern Europe on February 28 was an extremely rare type of meteorite. Fragments of the space rock discovered on a driveway in the Cotswolds could provide answers to questions about the early history of the solar system and life on Earth.





    Almost 300 grams (10.6 ounces) of the meteorite have been collected from the small Gloucestershire town of Winchcombe by scientists, who said the rock was formed of carbonaceous chondrite. The substance is some of the most primitive and pristine material in the solar system and has been known to contain organic material and amino acids -- the ingredients for life.

    There are approximately 65,000 known meteorites on Earth, the museum said. Only 1,206 have been witnessed to fall, and of these, only 51 are carbonaceous chondrites.

    The space rock, the museum said, was similar to the sample recently returned to Earth from space by the Japanese Hayabusa2 mission, which returned about 5.4 grams of fragments from the asteroid Ryugu, according to the Japan Aerospace Exploration Agency.


    Meteorite that fell on UK driveway is 'extremely rare' and may contain 'ingredients for life' - CNN


    The Japs must be a bit pissed, they spend how much Yen and time to get 5.4 grams from the surface of an asteroid, then the Brits have 300 grams dropped on their doorway.


    The into video is short and interesting for those that don't know their comet from their meteor.


    Comet - Chunk of ice.
    Asteroid - chunk of rock or metal, orbiting the sun.
    Meteor - asteroid or part of an asteroid that enters our atmosphere and burns up.
    Meteorite - piece of said meteor that lands on the Earth.

    what's the deal with this?
    Did this piece just drop off?
    WTF, did they forget the locktight ?
    How many nuts would have to unwind for this to happen ?

    Well, great! Now I know more about this nice little drone. According to NASA's plans, Ingenuity will make its first flight in April. I would be very glad if it occurred earlier than scheduled. Ingenuity can easily become a founder of an absolutely new type of spacecraft to investigate planets. This helicopter will help scientists get the necessary experience, and, perhaps, we'll start sending similar missions to other planets. It would be good.

    Nice videos of a Falcon upper stage reentering and burning up in the high atmosphere. Usually SpaceX deorbits them over empty areas of the southern Pacific. But Starlink launches max out the capacity of Falcon launches with booster recovery and sometimes the remaining propellant is not enough for targeted deorbit. This one came down after 3 weeks. Good explanations in the video.

    The hunt is on to find the next generation of astronauts - and for the first time in over a decade, the UK could find a new man or woman to send into space.

    The European Space Agency is searching for four to six candidates ready to train for space travel, with applications opening on 31 March 2021.


    Dr Jackie Bell has dreamt of going into space.
    Among those hoping to make the cut is Dr Jackie Bell, a mathematician and physicist from North Liverpool.

    The 32 year old has been preparing for this moment almost all her life:

    It really is a kind of now or never moment for people who, just like myself, have been training for this.

    Dr Jackie Bell
    Opportunities to go to space are rare - the ESA has only recruited four times since 1978.

    Their last search launched the space career of astronaut Tim Peak, who travelled to the International Space Station in 2015.


    Tim Peake was the first British recruit through the ESA astronaut programme in 2009.
    Credit: ESA
    Tim Peake's career highlights:

    In Peake condition: Britain's next official astronaut prepares to blast off
    Watch the space walk 'etched on my memory forever'
    Tim Peake sends the Queen a message from space

    Stunning pictures from the International Space Station
    Tim Peak receives honours from the Queen at Windsor

    Dr Bell has been building up all the technical, language and physical skills she might need.
    The competition is likely to be fierce, with thousands expected to apply.

    Hopefuls like Jackie will have to prove they have the right skills to join the ESA's astronaut corps and complete the extensive training.

    As well as getting her pilot's license, Dr Bell has learnt Russian, and practised working under pressure:

    Dr Bell was the first person in her family to go to university - but had early inspiration by watching Red Dwarf with her dad and seeing Liverpudlian actor Craig Charles play the part of Dave Lister.

    She recalls "a Scouser on TV in space - that was a big moment you know, at the age of eight I thought that it could be very much real."


    Successful candidates will eventually be deployed to the International Space Station.
    Credit: ESA
    Since then, Jackie has developed a passion for communicating science, and earned a PhD in Theoretical Particle Physics.

    Now, she wants to be the first scouser in space for real.

    I'm going to be applying because I am serious about it. Traditionally people go through the RAF or the Army route. But hopefully with them looking for someone or some people a bit more diverse, I'll have what it takes.

    Dr Jackie Bell
    "You can only hope. And if not, I just want to encourage more people from Liverpool to apply as well - to try and get a Scouser in space would be the ultimate dream I think."


    Could this be your new view?

    It's an 18 month process before the next generation of astronauts are chosen.
    Shalom

    Some big numbers


    Nasa is building a spacecraft to reach an asteroid worth $10 quintillion


    Nasa has officially begun the final assembly of its Psyche spacecraft, which will explore an asteroid of the same name worth $10 quintillion.
    The space agency shared images and video of the craft being put together from itsJet Propulsion Laboratory in Southern California. The process should take a year before it is shipped to Cape Canaveral in Florida to launch, scheduled for August 2022.

    Space News thread-psyche-jpg


    Space News thread-rock-jpg



    The news follows the shipment of the Solar Electric Propulsion (SEP) Chassis to the laboratory, which is the key component of the spacecraft. The large structure – approximately the size of a van – features a two-meter-wide high-gain antenna, a massive frame that will hold scientific instruments, and red protective covers to safeguard delicate components.

    Assembly began on 16 March, when engineers examined the subsystems, the flight computer, the communications system, and the low-power distribution system to ensure they all worked in harmony. With the arrival of the chassis, the remaining hardware can be tested and installed.
    “Seeing this big spacecraft chassis arrive at JPL from Maxar is among the most thrilling of the milestones we’ve experienced on what has already been a 10-year journey,” said Arizona State University’s Lindy Elkins-Tanton, the principal investigator of the Psyche mission.

    “Building this complex, precision piece of engineering during the year of Covid is absolutely a triumph of human determination and excellence.”
    The assembly of the craft will not be easy, with scientists working against the clock to get it ready before launch date. “It’s exciting watching it all come together, and it’s the part of the project life cycle that I love the most,” said Psyche Project Manager Henry Stone of JPL.

    Space News thread-psyche-2-jpg



    “But it’s a really intense phase as well. It’s intricate choreography, and if one activity runs into a problem, it can impact the whole process. Staying on schedule at this phase of the mission is absolutely critical.”

    The Solar Electric Propulsion (SEP) Chassis, a main component of NASA’s Psyche spacecraft was delivered to JPL, where assembly, test, and launch operations are underway.

    Some aspects have been made easier, though: the SEP Chassis has most of the hardware components already integrated, such as the electrical, propulsion, thermal, and guidance and navigation system.

    This was handled by Maxar Technologies, which also gave the craft a superefficient propulsion system to push it through space – as well as two huge, five-panel solar panels to keep it running.


    “Delivering the SEP Chassis to NASA’s JPL is an incredible accomplishment for us at Maxar,” said Steven Scott, Maxar’s Psyche program manager.

    NASA is preparing a large cube sat for a deep space mission. Living cells will be exposed to deep space radiation to check, how they are affected in a 6 months mission. Yeast is quite similar to humans so valid data can be gained for long deep space missions with people.

    NASA’s BioSentinel Team Prepares CubeSat For Deep Space Flight | NASA


    Because human cells and yeast cells have many similar biological mechanisms, including for DNA damage and repair, BioSentinel’s experiments can help us better understand the radiation risks for long-duration deep space human exploration.
    BioSentinel will test new technology with the BioSensor payload, a kind of “living radiation detector.” At the heart of the BioSensor are the microfluidic cards that house yeast cells. As the cells get activated in space, they will sense and respond to the damage caused by space radiation. Here, a BioSentinel team member works on assembling a BioSensor payload, connecting thermal and optical units to a microfluidic card. During BioSentinel’s experiments, these components will warm the cards – and the yeast cells they house – and measure growth and activity in response to space radiation damage.
    Space News thread-acd20-0070-013-jpg


    Integration and test engineer Dan Rowan works on internal components of BioSentinel’s CubeSat in a clean room at Ames. These “spacecraft guts” include a radio, batteries, other spacecraft subsystems, and BioSentinel’s two instruments – the BioSensor payload and a radiation detection instrument. The latter measures and characterizes the radiation environment; its results will be compared to the BioSensor payload’s biological response.

    "A Russian-made Soyuz rocket has lifted off from a cosmodrome in the Kazakh desert. It will now carry its crew – two Russians and one American – to the International Space Station, orbiting more than 400km above the Earth.
    The manned capsule carrying the team is named after Yuri Gagarin, who made history on April 12, 1961, when he became the first person to orbit the Earth."

    Nothing unusual. Except:

    There is a video of the launch at the report page:

    Poekhali! Russian spaceship named after Yuri Gagarin blasts off almost sixty years after Soviet cosmonaut’s record-smashing flight — RT Russia & Former Soviet Union

    The video shows the rocket engines igniting, the exhaust appearing to the left and then the rocket accelerating upwards. There was no engulfing of the rocket in exhaust and the rocket exhaust once it lifted off was clear with bluish cones clearly visible.

    Why do some rocket launches appear quite explosive and this particular rocket launch so clean?

    Is it because the initial exhaust flow is channelled away better, the rocket is relatively small/light weight, the engines are designed differently or the type of fuel used?
    A tray full of GOLD is not worth a moment in time.
