I am one of the few African-American aerospace engineers who helped design the Apollo spaceships that took men to the Moon. My great-grandfather was a slave in Claiborne, Alabama, who used primitive tools to work the land. My father was born in Alabama before the Wright brothers made mankind’s first flight. He lived to see men walk on the Moon, twin robotic biology labs land on Mars, and a fleet of four space probes on their way to the stars. But many black people, like the late Reverend Ralph Abernathy, felt that the money used to make these amazing things happen would have been better spent on helping the poorest descendants of American slaves.

Beresheet (which means “Genesis” in Hebrew), Israel’s first Moon mission spacecraft has sent an amazing selfie with Earth in the background today.
In the photo, a plaque on the side of moon lander features the flag of Israel and phrases “Am Yisrael Chai” (which means roughly “The Jewish nation lives” or “the people of Israel are still alive”) and “small country, big dreams”.

American astronaut Anne McClain, who is a part of Expedition 58/59 to the International space station, shared the beautiful (and cute) photo below on her Twitter account, saying “Yes, buddy, that’s your Mother Earth. Isn’t she beautiful?”.

On March 3, 2019, at 10:51 UTC (05:51 EST), SpaceX Demo-1 Crew Dragon autonomously docked to the International Space Station’s Harmony module forward International Docking Adapter (IDA), becoming the first commercial crew spacecraft arrived at the International Space Station (ISS). Here’s the video of the docking process.

If we want to colonize Mars in the future, it would be better for us to terraform the planet, in order to make the colonization process safer and sustainable. But, terraforming Mars will be a real challenge for humanity.

Finnish 3D artist Kimi Talvitie has made some really impressive 3D models of SpaceX’s stainless steel Starhopper (the shorter test vehicle of Starship), Starship (previously known as the BFS – Big Fragging Spaceship) and Super Heavy booster (previously known as the BFR – Big Fragging Rocket) and published them on his Twitter account. They are amazing!

To able to reach the space, we need rockets. Rocket engines work by action and reaction (“To every action, there is always opposed an equal reaction” Notes 1) and push rockets forward simply by expelling their exhaust in the opposite direction at high speed and can, therefore, work in the vacuum of space. Space rockets are usually enormous in size, because the bigger the rocket is, the more thrust can produce its engine and can carry more weight into the orbit. Here are the 10 tallest rockets ever launched in the history of space exploration.

One of the most interesting photos in history: the entire Earth clearly reflects off the side of a… car!

This will go down as one of the greatest videos in history, and you must share it with everyone you know. It is one of the great achievements our species has ever done. SpaceX’s Falcon Heavy test flight was successful and the rocket’s upper stage, together with Elon Musk’s electric sports car Tesla and the dummy “Starman”, are on their way to Mars.
When Falcon Heavy lifted off, it became the most powerful operational rocket in the world by a factor of two. This rocket that may one day carry humans to the Moon or Mars! With the ability to lift into orbit nearly 64 metric tons (141,000 lb)-a mass greater than a 737 jetliner loaded with passengers, crew, luggage and fuel-Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost. Falcon Heavy draws upon the proven heritage and reliability of Falcon 9.

Tech Insider published a video titled “How NASA, SpaceX, and Blue Origin’s Monster Rockets Compare”. Still, the old Saturn V, which was used by NASA between 1967 and 1973 and took humans to the Moon, is the biggest and strongest rocket ever built. But new rockets are coming and that’s finally about the change. Here is the past and future monster rockets comparison:
