SpaceX’s 1st upgraded Dragon cargo ship docks itself at space station with science, goodies and new airlock

Posted by in categories: robotics/AI, science, space travel

Its SpaceX’s first-ever autonomous Dragon docking.


A SpaceX Dragon cargo ship arrived at the International Space Station today (Dec. 7) to deliver vital supplies for NASA and try something brand-new: park itself without the help of astronauts.

The private spaceflight company used a Falcon 9 rocket to launch CRS-21, the first flight to use the upgraded version of its Dragon cargo spacecraft, to the space station Sunday (Dec. 6) from NASA’s Kennedy Space Center in Florida. The vehicle autonomously docked with the orbiting laboratory today at 1:40 p.m. EST (1840 GMT), parking at the zenith, or space-facing, side of the station’s Harmony module.

US Space Force and NASA Looking to Privatize Nuclear Spacecraft Production

Posted by in categories: chemistry, Elon Musk, nuclear energy, space travel

LOS ANGELES, CA / ACCESSWIRE / December 7, 2020 / US Nuclear (OTCQB: UCLE) is the prime contractor to build MIFTI’s fusion generators, which could be used in the relatively near future to power the propulsion systems for space travel and provide plentiful, low-cost, clean energy for the earth and other planetary bases once our astronauts get to their destination, be it the moon, Mars, Saturn or beyond. Chemical powered rockets opened the door to space travel, but are still far too slow and heavy even to travel to distant planets within our solar system, let alone travel to other stars. Accordingly, NASA is now looking to nuclear powered rockets that can propel a space vessel at speeds close to the speed of light and thermonuclear power plants on the moon and Mars, as these are the next steps towards space exploration and colonization.

The US Energy Secretary, Dan Brouillette, recently said, “If we want to engage in outer space, or deep space as we call it, we have to rely upon nuclear fuels to get us there… that will allow us to get to Mars and back on ‘one tank of gas’.” This is made possible by the large energy density ratio which makes the fuel weight for chemical fuels ten million times higher than the fuel that powers the fusion drive. NASA is now relying on private companies to build spaceships: big companies like Boeing, but more and more on high-tech startups such as Elon Musk’s Space-X, Jeff Bezos’s Blue Origin, and Richard Branson’s Virgin Atlantic.

While nuclear fission has been considered as a basis for the next generation of rocket engines, the fuel used for fission is enriched uranium, which is scarce, costly, unstable, and hazardous. On the other hand, thermonuclear fusion uses a clean, low-cost isotope of hydrogen from ordinary seawater, and one gallon of this seawater extraction yields about the same amount of energy as 300 gallons of gasoline.

Blue Origin continues work on BE-7 lunar lander engine

Posted by in category: space travel

WASHINGTON — Blue Origin has achieved a new milestone in the development of the engine that will power the lunar lander it seeks to provide for NASA’s Artemis program.

The company announced Dec. 4 that it started a fourth series of hotfire tests of the thrust chamber for the BE-7 engine. That thrust chamber was fired for 20 seconds on a test stand at NASA’s Marshall Space Flight Center, where the company did previous tests of the engine.

“This thrust chamber test measured the ability to extract energy out of the hydrogen- and oxygen-cooled combustor segments that power the engine’s turbopumps, the key to achieving high engine performance,” said John Vilja, senior vice president of engines at Blue Origin, in a company statement.

Scientists invent technology that can extract oxygen and fuel from Mars’ salty water in huge step forward to colonising Red Planet

Posted by in categories: Elon Musk, robotics/AI, space travel

Space exploration company SpaceX’s founder and chief executive officer Elon Musk on Tuesday said he expected humans to land on Mars in six years. He also said that SpaceX plans to launch an unmanned spacecraft and land on Mars in two years, with a chance of the first human landing on Mars in four years instead of six.

United States’ space agency NASA’s Perseverance rover which was launched in July 2020 is scheduled to land at Jezero Crater on Mars on 18 February 2021. It will look at signs of ancient life and collect rock and soil samples for a possible return to Earth.

It is carrying instruments that will use high-temperature electrolysis but the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) will be producing oxygen only, from the carbon dioxide in the air.

SpaceX Will Launch Remote Controlled Racecars to Lunar Surface

Posted by in categories: education, space travel

The racecars themselves will be partially designed by six teams of high school kids from across the country, as New Atlas reports. The best two teams emerging from a series of challenges “will win a once-in-a-lifetime opportunity to build and race two vehicles on the Moon,” according to a February press release.

“Competitors will then race their rovers remotely, navigating through harsh terrain, racing around a sphere of cameras, which will capture every aspect,” the statement reads.

Moon Mark CTO Todd Wallach told New Atlas that teams will have “near real time visuals, telemetry and command and control” of the racecars.
