Orion's view of the Moon and the Earth


Video oldindan ko‘rish uchun mavjud emas
Telegram'da ko‘rish
The final five-and-a-half minutes of images leading up to the DART spacecraft’s intentional collision with asteroid Dimorphos. The DART spacecraft streamed these images from its DRACO camera back to Earth in real time as it approached the asteroid. This replay movie is 10 times faster than reality, except for the last six images, which are shown at the same rate that the spacecraft returned them. Both Didymos and its moonlet Dimorphos are visible at the start of the movie. At the end, Dimorphos fills the field of view. The final image in the movie shows a patch of Dimorphos that is 51 feet 16 meters) across. DART’s impact occurred during transmission of the final image to Earth, resulting in a partial picture at the end of this movie. Didymos is roughly 2,500 feet (780 meters) in diameter; Dimorphos is about 525 feet (160 meters) in length.

Artemis I is scheduled to launch in 9 days!

During this flight, the uncrewed Orion spacecraft will launch on the most powerful rocket in the world and travel thousands of miles beyond the Moon, farther than any spacecraft built for humans has ever flown, over the course of about a three-week mission.

This is why the Earth Doesn't Orbit the Sun💥
Rather, the Earth and the Sun orbit a point between the Earth and the Sun. Barycentre is an Astronomical term for a point between two or more celestial bodies that orbit one another and it is the point about which the bodies orbit. In the Sun-Earth orbit case, the Barycentre is inside the sun's surface. So the Sun keeps wobbling around it, while Earth orbits the Barycentre. It is only for the Sun-Jupiter system, that the Barycentre is just outside the Sun's surface.

How do Barycentres help in finding Exoplanets?🪐
If a star has planets, the star orbits around a barycenter that is not at its very center. This causes the star to look like it’s wobbling. Exoplanets are very hard to see directly. They are hidden by the bright glare of the stars they orbit. Detecting a star's wobble is one way to find out if planets are orbiting it. By studying barycenters—and using several other techniques—astronomers have detected many planets around other stars!

NASA wants another moon lander for Artemis astronauts, not just SpaceX's Starship
The agency announced March 23 that it plans to support the development of a second privately built crewed lunar lander "as early as the 2026 or 2027 timeframe." The announcement comes after NASA (under budget constraints) pivoted its multiple-source landing contract to a single-source in favor of SpaceX, which multiple companies protested last year...Read More

Chinese lunar and Red Planet missions send new science back to Earth
China released new results from the moon and Red Planet at the Lunar and Planetary Science Conference (LPSC), held virtually and in Texas starting March 7. The Tianwen 1 Martian orbiter and rover mission and the lunar sample return mission Chang'e 5, produced results ranging from rock formation conditions to geological context of the landing area...Read More

OneWeb's internet satellites will launch on SpaceX instead of a Russian Soyuz
OneWeb announced March 21 a deal with SpaceX — a competitor in the satellite internet business — to get its spacecraft to low Earth orbit (LEO). This follows a tricky situation that occurred in the wake of Russia's ongoing invasion of Ukraine. OneWeb had been set to do a launch aboard a Russia-run Soyuz earlier this month, but that agreement fell apart and the Soyuz was rolled off the launch pad, along with the satellites...Read More

Did you Know?🚀
It is a common misconception that the SLS Core Stage and Space Shuttle External Tank are painted orange in color. But the orange color comes from insulation that covers the vehicle's liquid hydrogen and oxygen tanks. This is why the SLS Core Stage and Space shuttle's external fuel tank is orange. It is not painted.
In fact, in STS-1 and STS-2, external tanks were painted white to protect the insulating foam from ultraviolet light damage. It was later determined that the foam was not damaged by UV light, but merely changed color from a light tan to orange when exposed to sunlight.

Space Shuttle Enterprise
Enterprise, named after the fictional spacecraft "Enterprise" in Star Trek, was the first orbiter of NASA's Space Shuttle Program. Although, it never went to space, it was used to gather an enormous amount of data on controlling the space shuttle inside Earth's atmosphere. It didn't have heatshield and engines. Moreover, it played a major role in the development of upcoming space shuttles.

JWST's Thermal Protection System
JWST has an enormous sunshield made up of 5 layers of Kapton. The sunshield will allow the telescope to cool down to a temperature below 50 Kelvin (-370°F, or -223°C) by passively radiating its heat into space. The near-infrared instruments (NIRCam, NIRSpec, FGS/NIRISS) will work at about 39 K (-389°F, -234°C) through a passive cooling system. The mid-infrared instrument (MIRI) will work at a temperature of 7 K (-447°F, -266°C), using a helium refrigerator, or cryocooler system.

All these precautions against heat are taken as the telescope detects infrared light, which is basically heat and it's very sensitive. Therefore, the thermal protection system not only shields the sensors from the heat produced by the Sun, but as well as the heat emitted by its own systems.

This Day in 1982
40 years ago on this day, STS 3 lifted off from Kennedy Space Centre LC39A with Commander Jack R. Lousma Pilot C. Gordon Fullerton.The primary objectives of the flight were to continue testing the Remote Manipulator System (Canadarm), and to carry out extensive thermal testing of Columbia by exposing its tail, nose and top to the Sun for varying periods of time.

Quilite Advanced Flexible Reusable Surface Insulation (AFRSI)
These tiles were used to insulate the Space Shuttle from the high temperatures generated by the orbiter’s friction with the Earth’s atmosphere on re-entry. The black tiles on the lower portion of the Shuttle have to be able to withstand temperatures of more than 1260°C, but these particular tiles were used to protect areas where the temperatures experienced were less than 650°C. Silica was used because of its durability and resistance to extremely high temperatures.

The first VTVL rocket!
The DC-X, short for Delta Clipper Experimental, was an uncrewed prototype of a reusable single-stage-to-orbit launch vehicle built by McDonnell Douglas in cooperation with United States Department of Defense in the 80s. It was capable of performing propulsive landings like a Falcon 9 booster does today.
The project was later taken over by NASA and a more developed version called the DC-XA or Delta Clipper Experimental Advanced was born.

Did you know?🚀
Space Shuttle was originally meant to be a fully reusable vehicle consisting of 2 reusable stages. The concept vehicle was known as DC-3. It would have a jet engine powered lower stage which would fly back to a runway after separation. The upper stage could relaunch almost hours just after landing with little to no refurbishment. It was supposed to make a hundred flights in one year!

Unfortunately, due to budget cuts by Congress, NASA had to abandon the plan of DC-3 and go on with the Space Shuttle design we know today.
